Undefined VBlank interval on Ubuntu 20.04 with second display, Radeon 5100 card

stevevanhooser · September 30, 2021, 12:41pm

Hi all -

I am setting up a new machine that will be repeated 3x, and I’m having some sync trouble. We have priority support but I am asking in public in case it benefits anyone (hopefully it all benefits everyone).

My machine runs Ubuntu 20.04 (fully updated as of yesterday Ubuntu 20.04.3 LTS (GNU/Linux 5.11.0-37-generic x86_64)) and has a built-in Intel graphics board for the display that the operator uses, and a Radeon 5100 for the display that drives a CRT at 100 Hz refresh (connected through an HDMI adapter). The system is set up as a 2 screen system (with “ZaphodHeads”), where screen 0 is the monitor connected to the Intel board and screen 1 is the monitor connected to the Radeon 5100 board.

I have installed the current version of Psychtoolbox using the neurodebian package for Matlab. I have installed the matlab-support package and allowed it to rename the C++ libraries. I run Matlab R2021a Update 5 (9.10.0.1739362) 64-bit (glnxa64).

Symptoms: Psychtoolbox runs fine on a 60Hz LCD display connected to the Intel board (screen 0), but I have no VBL sync information on the Radeon-connected CRT. It appears to me that it is using the MESA driver rather than the proprietary driver (as it should). If I force Psychtoolbox to ignore the sync failures, it will draw the stimuli on the CRT just fine but of course there is terrible tearing.

Now, the debugging information. I’ll paste the report when I try to use the Radeon-connected monitor (which fails), the report when I use the Intel board (which succeeds on an LCD but I’d like to use the nice Radeon 5100 for my work), and my xorg.conf information and my custom xrandr setup, and some libGL errors that I don’t think are relevant but might be.

The debugging info is too long to fit into one message so I will post the rest in a reply.

One or more internal checks (see Warnings above) indicate that synchronization
of Psychtoolbox to the vertical retrace (VBL) is not working on your setup.

This will seriously impair proper stimulus presentation and stimulus presentation timing!
Please read ‘help SyncTrouble’ for information about how to solve or work-around the problem.
You can force Psychtoolbox to continue, despite the severe problems, by adding the command
Screen(‘Preference’, ‘SkipSyncTests’, 1); at the top of your script, if you really know what you are doing.

xrandr --screen 1 --newmode “800x600_100” 67.25 800 848 928 1056 600 603 607 639 -hsync +vsync
xrandr --screen 1 --addmode DisplayPort-3 800x600_100
xrandr --screen 1 --output DisplayPort-3 --mode 800x600_100

Random errors from terminal that is running Matlab:
These occur regardless of which screen I am using, either screen 0 (where it works) or screen 1 (where it doesn’t work). I’ve been ignoring them but I put them here in case they are diagnostic of anything.

libGL error: failed to create dri screen
libGL error: failed to load driver: i965
libGL error: failed to create dri screen
libGL error: failed to load driver: i965

Thanks all in advance!

Hi Steve,

i’d need two things from you:

A valid authentication token, generated from your license key via the PsychPaidSupportAndServices to bill this request on your license.
The ~/.local/share/xorg/Xorg.0.log X log file.

Thanks,

Thanks. The xorg.conf is a bit overcomplicated and suboptimal, and ZaphodHeads only makes sense if one wants to split up one physical graphics card (gpu) into multiple logical gpus for separate X-Screens. Otherwise it sometimes hurts. But the X log suggested it worked anyway, with OpenGL hw acceleration on Screen 1.

What is the output when running glxgears from a terminal on screen 1?

LIBGL_DEBUG=verbose glxgears -display :0.1 -info
maybe also for reference on the Intel:
LIBGL_DEBUG=verbose glxgears -display :0.0 -info

Does it work in octave if you sudo apt install octave-psychtoolbox-3?

That output makes no sense, very mysterious. But it at least also fails for glxgears, so we can ignore Matlab/Octave/PTB problems.

As a general comment, life becomes much easier in terms of avoiding complexity and corner cases if you only use one graphics card - the AMD - for both X-Screens. That gpu should be plenty powerful enough to driver both your monitors without timing problems.

So simply disabling the intel gpu in the firmware settings of your machine and creating a simple xorg.conf via our XOrgConfCreator would be probably the most straightforward approach. Also, PTB can only deal with one gpu wrt. extra low-level diagnostics and tricks.

Maybe try this simplified xorg.conf and see where it gets us:

Section "ServerLayout"
  Identifier "Dualgpu"
  Screen 0 "Screen0" 0 0
  Screen 1 "Screen1" LeftOf "Screen0"
EndSection

Section "Device"
  Identifier "intel-gpu"
  Driver "modesetting"
  BusID "PCI:0:2:0"
EndSection

Section "Device"
  Identifier "amd-gpu"
  Driver "amdgpu"
  BusID "PCI:1:0:0"
EndSection

Section "Screen"
  Identifier "Screen0"
  Device "intel-gpu"
EndSection

Section "Screen"
  Identifier "Screen1"
  Device "amd-gpu"
EndSection

This would get rid of ZaphodHeads - not needed for dual-x-screen, dual-gpu.
It would switch the intel gpu to the more modern modesetting driver, which would in turn enable the modern iris OpenGL driver for Intel graphics, and the more modern DRI3, matching the modern DRI3 for the AMD gpu.

Obviously keep a backup of your old xorg.conf, in case i made a typo above.

Then logout/login and repeat the glxgears exercise, maybe run the Matlab test again, and send the new xorg log as well if it doesn’t work.

Edit: Fixed some quotation marks in the posted xorg.conf snippet, which could throw the machine a bit off. Damn quoting in the forum…

Thanks for the input Mario!

Mixed news / results.

My Dell BIOS does not have the ability to “turn off” the Intel graphics card. I can select which card is “primary”, and I tried selecting the ATI card as the primary. Still, I got the same behavior, with the xorg.conf that you suggested and a new one that only used the ATI Radeon card.

For this particular stimulus computer, I want to drive a CRT, and the Radeon is really overkill. The CRT is pretty small (800 x 600) and I only run it at 100 Hz. I tried an alternate strategy of just driving both monitors with the Intel card, and it seems to work fine, no glitches, no tearing, very precise frame timing.

I have two other “mirrors” of the setup that I want to use to drive Display++ monitors, and I think I need the Radeon to address that big space at high frame rates. For that I will consult Ian to see what his exact setup is. I know he does that.

Thanks!
Steve

stevevanhooser · October 1, 2021, 12:41pm

One last question: do you know how to disable the Intel in firmware in a way other than the bios? I tried Googling that, but all I could find were some people using nVidia cards and the respondents said “no, don’t do that, do this other thing instead” so I never learned how to do it.

You said you installed from NeuroDebian, right? If so, have you run PsychLinuxConfiguration once, to go through the Linux setup steps that our DownloadPsychtoolbox/UpdatePsychtoolbox would usually do, and then rebooted for extra measure?

What is the output of ls -l /dev/dri/ and of id in a terminal?

Simpler setup should certainly work. What happens without a xorg.conf file at all and only a monitor connected to the AMD and the machine rebooted?

And yet another thing to try would be:

echo $MESA_LOADER_DRIVER_OVERRIDE

MESA_LOADER_DRIVER_OVERRIDE=radeonsi LIBGL_DEBUG=verbose glxgears -display :0.1 -info

I digged through the source code a bit and the reason why software rendering is used on X-Screen 1 for the AMD is that the AMD radeonsi OpenGL driver does not get loaded, but instead the i965 driver for Intel graphics chips, which can’t drive the AMD gpu, so it falls back to the software llvmpipe renderer. The above override would try to enforce use of the radeonsi driver, instead of the auto-(mis)detected i965 driver.

What is completely mysterious is why the wrong driver got chosen by OpenGL clients like glxgears or PTB, when the X-Server itself correctly detected that it should use radeonsi for Screen 1.

It is almost as if something or someone else already set MESA_LOADER_DRIVER_OVERRIDE to the utterly wrong value i965 somewhere and that is screwing things up. But that doesn’t happen on any default Ubuntu installation.

Thing is, my MBP 2017 has an almost identical hardware setup, and almost identical software setup, and dual-gpu works fine, so something must be really weirdly misconfigured in some strange way.

Our workstations only have the WX5100 GPUs, so I don’t have any worries of which GPU to use where. The major problem with the Display++ is it needs a dual-link-DVI adapter. We connect screen-0 to displayport-1 of the AMD GPU and the Display++ to screen-1 — we use displayport-3 outputting to a Displayport splitter[1] (so we can see a copy of the stimulus in in the operator room), and the output of the splitter goes to a mini-displayport>dual-link-DVI adapter to the Display++ — one caveat of using a Displayport splitter is that the Display++ needs to be the SECOND output of the splitter, otherwise our mirror display (which is a 144Hz gaming monitor that can also do 120Hz) is the one that gets priority and causes all sorts of problems when setting up the x-windows. We use a pretty basic xorg.conf made by PTB’s XOrgConfCreator, with 30bit output OFF, VRR OFF, modesetting OFF[2] and DRI/3 ON

[1] it was quite hard to find DP splitters that do simple mirroring, most of them we found seem to create a more advanced extended display. But working in China, we contacted the factory directly and the customised ours to only mirror…
[2] modesetting, whatever it is, is recommended but I had multiple problems getting it to work, and the performance is fine without it so leave it disabled.

Oh, no! MESA_LOADER_DRIVER_OVERRIDE was set in my .profile to i965. I had tried that initially (in my .profile and in ptb3-matlab) but it didn’t seem to take in my profile. However, when I use GETENV in Matlab, it is there. Argh! !!!

We have already taken the Radeon board out of that computer, so I don’t yet know if it would work with the two boards. We will take a look at that computer’s “twin”, which will drive a Display++, and I’ll let you know.

Thanks Mario!

Thanks Ian. I don’t have to split the display for the Display++ so hopefully it will work in a straightforward way.

Thanks!

Maybe, to save people like me from themselves, PTB-INFO in verbose (10) mode should also print out all of the environment variables.

That was almost certainly the reason. It was the only thing off and mysterious, and definitely the cause of the failures you observed.

I’d recommend switching to the xorg.conf i posted. It is much simpler and uses the modesetting-ddx video driver instead of the older intel-ddx video driver, which itself enables some performance optimizations, and the new iris OpenGL driver for higher performance, new features, and a modern OpenGL 4.6 instead of an older version from the 3.x series.

Btw., if your lab can afford it, i’d appreciate if you could buy some more priority support licenses and send the authentication tokens, so we can bill this to you. In total this took me at least 222 minutes of work time to resolve, whereas a single license grants 60 minutes of support, so as it stands, we would have lost over 400 Euros due to doing “overtime” on this. 3 more licenses would get us back into the plus.

We will probably have to make drastic changes to our support offerings soon. As it stands, the community membership program doesn’t work out at all, as most labs choose to free-ride instead of support us – you are one of the few exceptions who did the right thing early on, one of the first takers as far as i can see. And whenever some lab actually requests priority support, it almost always takes way more than 60 minutes, so the whole program loses us money at the current price point, instead of helping us.

Thanks,

Yes, we will buy some more licenses. I plan to have one “at the ready” in general.

Maybe shareware? If your lab uses it, pay $x per year? Maybe people don’t do that either. We have done that a couple of times. It’s invaluable software for us.

Best
Steve
