VPixx setup (first try)
Checking VPixx functioning after connecting it to PC and CRT for first time
2023-10-05 notes
I connected the Datapixx and the CRT monitor to the grogu PC today (and to each other, of course). I also connected the IR emitter.
I had to make a link to make a Datapixx.mex file. I chose Datapixx_octave5.mex.
VPixx (3DPixx) system seems to be working: I can see ImagingStereoDemo(1,1) (which uses the Datapixx option).
However, the LCD glasses flicker strongly; very noticeably. I think this must be because the CRT monitor is still using its default setting: 75Hz. I set the resolution to be 1600×1200 using the Xubuntu settings.
I looked over the old VNLab notes about xrandr and edid, but I think what I really need is a copy of the boots PC's xorg.conf file. I think the only HDD that might have this is the one labeled “tarballs.” I'll have to check this later.
- Yes, the
/tarballsHDD contains a fileboots.tar.gz.
Let's copy this to grogu, unzip it, and hope it has an xorg.conf file.

xrandr command line
Was able to change the display mode (both resolution and refresh rate) by doing this from command line, after putting the modified xorg.conf file in place at /etc/xorg.conf. (However, I later determined that the presence of an xorg.conf file is not necessary for the xrandr commands to work.)
xrandr --newmode "800x600_120.00" 83.00 800 856 936 1072 600 603 607 646 -hsync +vsync xrandr --addmode DVI-D-0 800x600_120.00 xrandr --output DVI-D-0 --mode 800x600_120.00
I was able to get both 1280×768 and 800×600 resolutions. (I can't tell for sure what the refresh rates were.) These modes, and the refresh rates that I wanted to associate with them, were available on the pull down menu accessible from the “Settings → Display” menu.
PTB Sync errors
However, PTB gave me nothing but errors. Couldn't run ImagingStereoDemo, nor VBLSyncTest, nor GarboriumDemo.
I tried turning off the SkipSyncTest (or similar name) procedures, but this just made Octave hang even worse, so I turned them back on.
To get PTB to work, I had to change the name of both versions of xorg.conf.new that I had moved to /etc/ back to their original names, so that there wasn't any xorg.conf file present in /etc/. I tried moving both xorg.conf.new (the file that I had Xorg -configure generate automatically) and xorg.conf.new.1284x768_120.00 (the file that I edited from xorg.conf.new to include the new mode indicated in its file name); both caused errors.
xorg.conf.new.SIMPLIFIED file
I think for the next step I will try to reduce the xorg.conf.new file's contents until PTB works with it in place.
I made a copy of xorg.conf.new called xorg.conf.new.SIMPLIFIED. I removed (commented out) many sections, then saved, copied it to /etc/, and renamed it as xorg.conf, and finally rebooted.
Limited success
RESULT: VBLSyncTest ran! This means that there was something in the original xorg.conf.new file that was causing the errors, and not necessarily the display mode information.
Next, I need to try inserting the display mode information into the file. But first, because it's similar, I'm going to try setting the monitor using xrandr from the command line, with xorg.conf.new.SIMPLIFIED in place.
RESULT: Interesting. xrandr did change the resolution to 800×600. However, PTB gave nothing but Sync errors for VBLSyncTest and GarboriumDemo (it wouldn't display them); but PTB did at least show the splash screen, which I didn't see at all last Friday (today is Monday). Then I used the GUI “Settings” to change the display to 1280×1024 at 90Hz – a setting that apparently comes with the monitor or something, because I didn't specify it anywhere. PTB ran! GarboriumDemo just showed a solid white screen, but VBLSyncTest worked successfully. ImagingStereoDemo worked and the flicker was higher frequency and thus less noticeable than last week when I ran it at 75 or 85 Hz (whatever the default for 1600×1200 is). Semi-yay!
Next, I'm going to try using xrandr to set the resolution to 1284×768 and 120Hz, just to see if that works whereas 800×600 didn't. Not sure why it would succeed, but seems worth a try.
RESULTS: Same pattern of results as with 800×600 at 120Hz. I guess I'll have to try editing xorg.conf.new.SIMPLIFIED again, perhaps adding more things from the boots PC's xorg.conf file, which is the only model I have for one that worked.
Next: wait, change of plans! While looking through VPixx's example xorg.conf files, I read that there exits “Psychtoolbox XOrgConfCreator”! I'm going to try that.

PTB XOrgConfCreator.m
I got VBLSyncTest and ImagingStereoDemo(1,1) to work in 1284×768 at 120Hz!
I used PTB's XOrgConfCreator function to create an xorg.conf file. It created the file
.Psychtoolbox/XorgConfs/90-ptbconfig_single_xscreen_amdgpu.conf
and (I think?)
/etc/X11/xorg.conf.d/90-ptbxorg.conf
I tried running PTB with this in place; same problems as above.
Modified version of PTB-generated xorg.conf file
Then I made a modified version of the file:
~/lab/equipment/stereopsis/CRT/90-ptbconfig_single_xscreen_amdgpu_MODIFIED.conf
I copied this to /etc/X11/xorg.conf.d/., and appended a string to the other .conf file already there so that it wouldn't be recognized as a .conf file (which, I suspect, is what gets the file read during init.). The other file is now named 90-ptbxorg.conf.CHANGEME
Success!
Then I switched the display resolution using the GUI; it might have been to *1024*x768 instead of to *1284*x768, but it was definitely 120Hz (well, very close to that). And everything worked!
(However, NOTE: GarboriumDemo was strangely dark – low brightness.)
I just checked ~/lab/equipment/stereopsis/CRT/90-ptbconfig_single_xscreen_amdgpu_MODIFIED.conf; it does specify 1024, not 1284. I guess that was the problem – I had misread my boots PC example xorg.conf file as saying 1284?
GPU not producing frame sequential stereo
2023-10-12 notes
The LCD glasses have only been working for a brief time, and it turns out that PTB had been throwing errors while the stereo presentation was happening.
I am going to try to install a different driver for the graphics card. First, I am documenting the current state of the gpu's driver, and the PTB errors.

Installing new amdgpu driver from AMD website
Backing up root partition
Backing up up the root partition prior to installing a new amd gpu driver for the Radeon RX 580.
The output below includes (last two lines) the Sandisk USB-C drive that I will use to back up the root partition. I guess I must have made the 77G partition so that I could dd grogu's root partition onto it uncompressed. That actually seems inefficient, since it probably wouldn't take that long to compress the dd output into a .img.gz file that would be significantly smaller.
anthony@grogu:~$ df -h Filesystem Size Used Avail Use% Mounted on tmpfs 1.6G 2.0M 1.6G 1% /run /dev/nvme0n1p4 77G 20G 53G 28% / tmpfs 7.8G 0 7.8G 0% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock /dev/nvme0n1p5 290G 2.9G 273G 2% /home /dev/nvme0n1p1 496M 44M 453M 9% /boot/efi tmpfs 1.6G 104K 1.6G 1% /run/user/1000 /dev/sdb2 36G 24K 34G 1% /media/anthony/4f41a542-5fff-4140-b640-deddb7ebf068 /dev/sdb1 77G 24K 73G 1% /media/anthony/85617021-8551-4ce1-8e99-519ad5db3788
I will go ahead and just dump the partition uncompressed into the larger partition of the Sandisk USB-C drive. I just verified the the two partitions are exactly the same size by doing df without the -h flag.
Usually the “of” argument would be a file, but because the USB drive partition is exactly the same size as the input partition, it seems like there wouldn't be any room left for file information (name, etc.). So I could try making the partition itself, without a file, the “of”.
I'm concerned this could backfire, so I'm just going to compress the output into a file after all.
$ sudo bash -c 'dd if==/dev/nvme0n1p4 | gzip > /media/anthony/85617021-8551-4ce1-8e99-519ad5db3788/grogu_root.img.gz'
Result: process took 15 minutes (no rounding). Output file is 11GB.
Copied the output file (grogu_root.img.gz) to a new dir I just made on the 3 TB storage HDD that is currently mounted at media/anthony/data11.
$ sudo cp -p /media/anthony/85617021-8551-4ce1-8e99-519ad5db3788/grogu_root.img.gz /media/anthony/data11/grogu/.
Came to my senses! Renamed grogu_root.img.gz to grogu_root_2023-10-13.img.gz in both instances.

I don't think it's the problem.

and then made a symlink from that to Datapixx_octave5.mex.
In /usr/share/psychtoolbox-3/PsychBasic/,

Altered xorg.conf file
I tried running the WIC study script, ClusterCircle.m, to see how it might run on this system. It couldn't paint the dots green. I thought that maybe the depth in bits parameter that PTB set when I ran XOrgConfCreator.m might have messed with the gpu's ability to portray color correctly (at least in PTB?), so I generated a new xorg.conf using XOrgConfCreator and examined it. It was minimal, but it lacked the line specifying DefaultDepth 30. So, I commented that line out of the xorg.conf file that I'm currently using. Then I rebooted the system, and ClusterCircle.m ran fine, showing green dots when it should have.
While I was at it, I removed the copy of the xorg.conf file in the critical directory (/etc/X11/xorg.conf.d/ and replaced it with a link to the copy of the file in ~/lab/equipment/stereopsis/CRT. That latter directory is part of a git repo, so now I won't have to worry about version control for a separate copy.
The name of the file and the location of the link that actually matter for controlling the CRT:
/etc/X11/xorg.conf.d/90-ptbconfig_single_xscreen_amdgpu_MODIFIED.conf
Again, the above is now a link, no longer a file.

Summary of this week's work: Need to contact VPixx
I couldn't fix the PTB problems by installing the different driver.
My next plan is to contact VPixx about this, giving them information from the things I've copied and pasted above and on other pages.
Future Plans
- Try using PTB with MATLAB instead of Octave
- Try AMDGPU-PRO driver
Installing PTB in MATLAB
2023-10-16 notes
http://psychtoolbox.org/download#Linux
The instructions included adding NeuroDebian repository to apt sources list. I chose the option that included non-free software sources.
PTB Errors
VBLSyncTest Errors
Seems like it was nothing but errors :(
Here is the very end of the output. (I had escaped out of the demo only a second or so after it started.)
PTB-WARNING: Flip 212 for window 10 didn't use pageflipping for flip. Visual presentation timing and timestamps are likely unreliable! PTB-WARNING: Something is misconfigured on your system, otherwise pageflipping would have been used by the graphics driver for reliable timing. PTB-WARNING: However, if you see this message only sporadically, this might be caused by onscreen popup messages a la "You have new mail!" or PTB-WARNING: "New updates are ready to install" etc. Being low on free system memory can cause this as well, especially on integrated graphics chips. PTB-WARNING: Read the Linux specific section of 'help SyncTrouble' for some other common causes and fixes for this problem. INFO: PTB's Screen('Flip', 10) command seems to have missed the requested stimulus presentation deadline INFO: a total of 151 times out of a total of 152 flips during this session.
Whoa, the display even seems to have switched back from 1024×768@120Hz to 1600×1200@75Hz on its own accord after that last demo, too!
For MATLAB, have to kill VPixx background process that is often (always?) running in background before doing the following, in order to get stereo scrips to work:
$ ps aux | grep -i vpix [note the ps number] $ sudo kill [vpixx ps number]
>> isReady = Datapixx('Open')
will work
Fixed VBLSyncTest Errors
Turns out I think the problem was that I still had Octave open and running PTB. I think the Datapixx was being counted as open in Octave, and therefore couldn't be counted as open in MATLAB, somehow. This is based on the error message I kept getting for Datapixx('Open').
In any case, the VBLSyncTest errors went away after I closed Octave, and did Datapixx('Open') in MATLAB.
ImagingStereoDemo(1,1) and HolesCrowd_PTB_TEST errors
Got the same problems as I have been having with Octave. ImagingStereoDemo(1,1) worked nicely once, but not again after that.
Namely, kept getting this error with both scripts:
PTB-INFO: Your script requests use of frame-sequential stereo, but your graphics card PTB-INFO: and driver doesn't support this. I will now fully enable the imaging pipeline PTB-INFO: and use my own home-grown frame-sequential stereo implementation. Note that this PTB-INFO: may not be as robust and high-performance as using a graphics card with native PTB-INFO: frame-sequential stereo support. But let's see what i can do for you...
That is, PTB switches the stereo mode to mode 11.
CONCLUSION: I guess I'll move on to installing the AMDGPU-PRO driver now.
Installing AMDGPU-PRO driver
I find it a little confusing to find this driver. There doesn't seem to be a reference to download something called “amdgpu-pro” as a driver or package, but the AMD website https://www.amd.com/en/support/linux-drivers does talk about “AMD Radeon PRO graphics.” Also, an ArchLinux site (https://aur.archlinux.org/pkgbase/amdgpu-pro-installer) has a page for a package called “amdgpu-pro-installer,” but it's in a format (https:*.git) I'm not familiar with. The good page https://linuxconfig.org/amd-radeon-ubuntu-20-04-driver-installation, in its “Proprietary AMDGPU-PRO drivers” section, simply points to the AMD drivers download page.
Downloading .deb file from "Linux® Drivers for AMD Radeon™ PRO Graphics" official site
Under the encouraging heading “Pro Driver.”
File is
amdgpu-install_5.5.50503-1_all.deb
Then, from the AMD site's instructions:
$ cd ~/Downloads # For Ubuntu: $ sudo apt-get install ./amdgpu-install-VERSION.deb $ sudo apt-get update
After doing that, this script is available:
anthony@grogu:Downloads$ which amdgpu-install /usr/bin/amdgpu-install
Did this:
$ amdgpu-install --usecase=workstation -y --vulkan=pro --opencl=rocr,legacy
I accepted the License Agreement from the terminal.
Got this error message:
Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: amdgpu : Depends: amdgpu-lib (= 1:5.5.50503-1620033.22.04) but 1:5.7.50700-1646729.22.04 is to be installed E: Unable to correct problems, you have held broken packages.
Solution: Turns out I had a newer version of the amdgpu-install* package already in the ~/Downloads dir. (*5.7* instead of *5.5*), so I just repeated the process using that one. No more errors.
Going to reboot and try Octave and then MATLAB PTB again.

White Screen of Error
Got an all-white screen, and unable to do anything other than move mouse pointer, after logging back in (i.e. the login screen was normal, and I typed my password first).
Used ctrl-alt-F1 to get to a TTY terminal, then did
$ less .bash-history
to see the recent amdgpu-install command.
Tried redoing that a few times in different ways and rebooting again, no difference.
Now I'm going to try doing
amdgpu-uninstall
Looks scary, though, so I said no the first time, decided to look up more info.
Did
amdgpu-uninstall
Perhaps unsurprisingly, got zero graphics (black screen) when rebooted.
Did
$ amdgpu-install -y --usecase=graphics --accept-eula
Then
$ sudo apt update
(actually, I'd been doing that after every time I ran an amdgpu-install command above)
The AMD drivers site instructions calls this the “All-Open Variant”
Got same problems/errors as before trying to install pro version of driver. But at least I can see the screen again.
OK, last thing to try for today:
amdgpu-install -y --usecase=workstation --accept-eula, but after doing amdgpu-uninstall first
Got White Screen of Error again!
OK, for reals last thing to try for today:
Followed the advice from this page:
firmware updating advice commands
Didn't help :(

$ uname -a $ Linux grogu 6.2.0-34-generic #34~22.04.1-Ubuntu SMP PREEMPT-DYNAMIC Thu Sep 7 13:12:03 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
Did it.
Some error messages came up while it was running.
After rebooting, still White Screen.
Performing steps 2 through 4 from above, again.
Still White Screen.
Tried logging in to root shell via Rescue Mode. Then did startx from root command line. Did get XFCE desktop, but Octave wouldn't run. Also, couldn't set the 120Hz mode (absent) using xrandr, because xrandr couldn't find the DVI-D-0 display.
Rebooted and did amdgpu-uninstall -y as anthony.
Then did amdgpu-install -y –accept-eula, rebooted, as sanity check.
No more White Screen of Error, just like previous time(s?) when I did the uninstall/install the basic version of the driver (no options) before.
No more PRB graphics card error messages!
BUT THIS TIME, WHEN I RAN PTB, NO MORE ERROR MESSAGES ABOUT THE GRAPHICS CARD!!!
I can run ImagingStereoDemo(1,1) and HolesCrowd_PTB_TEST.m without getting the PTB messages about my graphics card not providing sequential frame stereo, anymore. However, I still have the same phenomenon/issue/problem as before: sometimes I will get less than a minute of good stereo, but then the glasses will stop working completely. No extra message output comes from PTB after compared to before the stoppage, as far as I can tell.

See? No mention of the graphics card not providing frame-sequential something something. From the PTB output messages, it sounds like everything should have gone well.
I finally commented out the offending “SkipSyncTests” line that was at the beginning of the HolesCrowd_PTB_TEST.m script; made no difference other than getting rid of that warning message, I think.
Conclusion about amdgpu drivers
I conclude that installing the OEM Kernel, which did reduce the number of “Firmware missing” type warnings that I saw during the subsequent update-initramfs command step, must have updated the firmware or the driver or something, to an extent that enabled the graphics card to produce frame-sequential stereo for PTB.
Just had decent success with generic DLP-Link glasses

There was an aliasing sort of dark line that wandered up and down during HolesCrowd, and something like dropped frames (frames without any stereo) during ImagingStereoDemo.
Next steps
Create a file based on the example in the 3DPixx manual booklet, try to run it.
Could also try installing “All Open” and “Workstation” use case versions of the amdgpu driver, now that I have installed the OEM kernel.
VPixx version of ImagingStereoDemo.m
2023-10-23 notes
Created VPixx git repo
This past weekend, created a private repo named “VPixx” on my github account (acate).
I filled it with the directory of scripts that I downloaded from the “MyVpixx” website; the directory named “psychtoolbox–datapixx_demo_OCTAVE”. That is, the VPixx directory/repo contains a subdir. named “psychtoolbox–datapixx_demo_OCTAVE” which contains a bunch of octave scripts.
I am going to clone this repo onto grogu in the lab.
Testing the VPixx version of ImagingStereoDemo.m
The script is
.../Vpixx/psychtoolbox--datapixx_demo_OCTAVE/DatapixxImagingStereoDemo.m
Strange behavior of the system.
I could see in stereo for a few seconds, and then the glasses/system stopped working, much like it always has up to this point.
However, unlike before, the stereo started off showing uncrossed disparity (concave in the demo) for which the absolute disparity shrank gradually until the disparity became crossed (convex) until the perceived depth was too great to perceive any more. Then the glasses/system quit working.
I couldn't get the demo to work again, because I kept getting “Datapixx is not open” type errors, and then more errors when I tried the “Datapixx('Open')” command. However, unlike before, those error messages were accompanied by the message “unable to connect to server”. I Googled that with the term Datapixx, and found that there is something called a “device server” (see https://vpixx.com/developer/VPixx_Software_Tool_Update_Guide_3R5.pdf p. 2) that has to be running, according to the page I saw. I'm not sure about whether this is completely necessary, but I followed the advice I saw and did:
sudo systemctl start vpixx-device-server
… and this allowed the command
Datapixx('Open')
to work again.
However, even though I was able to get DatapixxImagingStereoDemo to work again, it worked similarly to the first time, but with a flipped sign of disparity: it started off displaying a (fairly shallow) crossed disparity (convex) bump, which then shrank until the Gaussian region became more and more strongly uncrossed disparity, until the disparity became too large, and then the glasses/system quit working again.
OpenGL info
glxgears output
Do this on command line as a way of testing OpenGL:
glxgears [then] glxgears -info
Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 657 frames in 5.0 seconds = 131.242 FPS X connection to :0.0 broken (explicit kill or server shutdown).

Output is rather long, so follow this link to see it:
Next steps
- Try downloading the VPixx scripts, but the versions for MATLAB instead of for Octave. Then run the same demos.
- Finally email Vpixx.
Ran PsychLinuxConfiguration
2024-01-22
Ran it on octave command line (i.e. no gui), as sudo.
Not sure whether I had run it before.
Tried ImagingStereoDemo again
Mostly successful! Only qualified by the following error/warning messages.
I ran octave from the command line as a regular user.

Package update problem after rebooting on 2024-01-22
I tried sudo apt update and sudo apt upgrade, but still get:
