Hello, PTB community!

I have some issues with my setup. I have a Linux PC and I needed to reinstall everything due to a graphic cards issue (I don’t know what happened but the PC started refusing to turn on.). I have 2 monitors connected to the PC and I tried to configure X screens with `XOrgConfiguraionCreator` and then selected my config with `XOrgConfigurationSelector`. I had no error but when I restarted the PC, both monitors were active, and this error showed when I launched MATLAB:

```auto
com.jogamp.opengl.GLException: X11GLXDrawableFactory - Could not initialize shared resources for X11GraphicsDevice[type .x11, connection :0, unitID 0, handle 0x0, owner false, ResourceToolkitLock[obj 0x1e237daf, isOwner false, <18e1ad01, 7d19a277>[count 0, qsz 0, owner <NULL>]]]

	... 2 more

```

I couldn’t find a solution to this. This seems a bit advanced for me but I can do my best with some guidance.

I am using MATLAB R2022b on Ubuntu 22.04. I installed PTB as recommended on the website. I reconfigured MATLAB (`sudo dpkg-reconfigure matlab-support`) and I installed low-latency kernel as well.

Looking forward to your reply!

This is a Matlab bug on Linux + Intel graphics chips, often reported to Mathworks, never fixed by them. It doesn’t affect Psychtoolbox at all, just plotting in Matlab.

Diagnosis and ok solution see:

>
> Background: This is a bug in the Matlab OpenGL hardware accelerated graphics and plotting system of all Matlab versions on Linux. I reported the problem to our Mathworks contact in the past, but the problem wasn’t resolved so far for more than a year. The bug triggers specifically on Intel graphics chips (and the just released Intel “Arc” discrete graphics cards) with the modern Intel iris graphics driver, e.g., as used on Ubuntu 20.04-LTS and later and similar modern distributions. The bug doe…

**Update with a possibly better solution on recent Matlab:**

What also worked for me on Ubuntu 20.04.6-LTS, Intel graphics, Mesa 21.2.6, with Matlab R2023b is the following older approach at fixing it:

While Psychtoolbox works perfectly as expected, Matlab itself spews some error messages, and plot()ing is broken. Apparently the Mathworks graphics team is just as bad at most basic graphics compatibility testing now as it was 3 years ago when plotting with AMD was broken for a very similar reason - History repeating, sad… Anyway, h…

Thanks Mario! It helped with the OpenGL issue.  
I still have a problem with XOrgConf. Although I can create an config file and select it without any error message on matlab, it doesn’t apply it after logout/login - even after restart. It is a similar issue with this: [AMD graphics card - #2 by mariokleiner](https://psychtoolbox.discourse.group/t/amd-graphics-card/123/2)  
I ran `sudo dpkg-reconfigure matlab-support` on terminal and it changed only GCC library names. `uname -r` reports 6.5.0-14-generic. There is no PTB output about XOrgConf. Do you have further suggestions?

It works on any supported system, unless you screwed up or do/did something unsupported or your system is odd. In any case, this is a case for paid support if our standard tips and instructions don’t work.

Hi Mario, we might screw up our system but we couldn’t track it down. So, could you help us to dig up the issue and solve it?

Hi Cemre,

validated - Up to 30 minutes of support.

How was Psychtoolbox installed? If it was via NeuroDebian, did you run `PsychLinuxConfiguration` once after installation or update?

What is the output (in a terminal) of:

`ls -l /etc/X11/xorg.conf.d/` and of `ls -l /etc/X11/ | grep xorg`

What is the output of `XOrgConfSelector` if you retry?

</div>

I followed the instructions for installation via NeuroDebian. I run PsychLinuxConfiguration as well.

On terminal:

```auto
user:~$ ls -l /etc/X11/xorg.conf.d/
total 4
-rw-rw-r-- 1 allg_admin allg_admin 931 Jän 17 11:27 90-ptbxorg.conf
user:~$ ls -l /etc/X11/ | grep xorg
drwxrwxr-x 2 allg_admin allg_admin 4096 Feb 7 11:49 xorg.conf.d
drwxr-xr-x 2 root root 4096 Jän 17 11:02 xorg.conf.d.old

```

On matlab:

```auto
>> XOrgConfSelector
You can choose from the following X11 configuration files:

1) 90-ptbconfig_1_xscreens_1_outputs_modesetting.conf
2) 90-ptbconfig_2_xscreens_2_outputs_modesetting.conf
3) 90-ptbconfig_single_xscreen_amdgpu.conf

Which one should i use? (Choose 0 for remove the current active file): 2

Copied the xorg.conf file into the X11 config folder under:
/etc/X11/xorg.conf.d/90-ptbxorg.conf

Troubleshooting tip in case of emergency:

In case something goes seriously wrong and you end up with a non-functioning GUI,
you can always press(*) 'CTRL+ALT+F3', which provides you with a text console. Then login
there, run octave or matlab from the text console and call XOrgConfSelector to remove
the troublesome config file. Or type this: rm /etc/X11/xorg.conf.d/90-ptbxorg.conf

(*)Apple computer users may need to press 'FN+CTRL+ALT+F3' instead of CTRL+ALT+F3

Now please logout and login again for the new configuration to take effect.

```

I was stuck on login screen when I tried logging in after logout. And I have two active monitors after restart. The stimulus monitor is still on and PTB uses two monitors as one screen.

Ok, so the access permissions and ownerships of the directory `/etc/X11/xorg.conf.d/` are wrong for some very weird reason (do you have some administrator administrating that machine who does weird stuff?), and would only allow the user “allg\_admin” to update the config file, ie. for your username “user” `XOrgConfSelector` would fail. It unfortunately fails silently though, as error reporting is insufficient in current PTB’s. I’ve improved it for the next upcoming PTB 3.0.19.8 release.

`PsychLinuxConfiguration` however, as of the current NeuroDebian releases (`PsychtoolboxVersion` reports 3.0.19.7.dfsg as version) , should be able to detect and fix permission/ownership issues by itself. Your user must also be added to the “psychtoolbox” Unix user group. If you type `id` in a terminal, the output should list “psychtoolbox” somewhere.

Can you rerun `PsychLinuxConfiguration` again? Then logout + login.

When it asks about adding users to the psychtoolbox user group, you should enter `user` as the name to add.

When it asks about “Should i create or configure a X11 config directory that is writable for you?” you should answer y for yes. After that, XOrgConfSelector should be able to write files. You could download the new future XOrgConfSelector from here, for improved error reporting:  
[https://raw.githubusercontent.com/kleinerm/Psychtoolbox-3/master/Psychtoolbox/PsychHardware/XOrgConfSelector.m](https://raw.githubusercontent.com/kleinerm/Psychtoolbox-3/master/Psychtoolbox/PsychHardware/XOrgConfSelector.m)

I guess your started off on that machine with an Intel graphics chip and then upgraded to an AMD gpu, and due to the silent failure XOrgConfSelector, there’s still an unsuitable file for the old Intel chip installed, leading to failure.

For reference, `ls -l /etc/X11 | grep xorg` should normally look similar to this - the word psychtoolbox and drwxrwsr-x being key:  
`drwxrwsr-x 2 root psychtoolbox 4096 Feb 2 17:28 xorg.conf.d`

`id` should contain the word psychtoolbox as well in its output.

Thanks Mario,

The lab was too busy, I could find a time slot today. You’re right, we started with an Intel graphic card and switched to an AMD, and it shows “Mesa Intel® HD Graphics 4400 (HSW GT2) / AMD® Radeon pro wx 320…” as graphic info, I didn’t noticed that before. Should I delete something or reinstall everything?

So, I logged in as allg\_admin this time.

```auto
allg_admin@14-PF062:~$ ls -l /etc/X11/xorg.conf.d/
total 4
-rw-rw-r-- 1 allg_admin psychtoolbox 958 Feb 15 15:34 90-ptbxorg.conf
allg_admin@14-PF062:~$ ls -l /etc/X11/ | grep xorg
drwxrwsr-x 2 root psychtoolbox 4096 Feb 15 15:34 xorg.conf.d
drwxr-xr-x 2 root root 4096 Jän 17 11:02 xorg.conf.d.old
drwxrwsr-x 2 allg_admin psychtoolbox 4096 Feb 7 11:49 xorg.conf.d_old

```

Then, I downloaded the new version of XOrgConfSelector, and created a new X screen configuration, and selected it. I didn’t get any error message again. After login/logout, the monitor on which I selected to show matlab GNU is not detected anymore. I restarted the computer and it gets signal at the beginning and shows Dell logo. After login, it is completely dark and it says “no signal”. Also XOrgConfCreator detects only one monitor.

So this looks good now. Proper file and directory ownerships and permissions, new XOrgConfSelector not complaining. `PsychLinuxConfiguration` did the trick 🙂 .

You can delete the old xorg.conf.d folders inside /etc/X11, e.g., on a terminal:

`sudo rm -rf /etc/X11/xorg.conf.d*old`

That 2nd graphics card could be the reason, if it is still active an has not been disabled in the EFI firmware settings when installing the new AMD card. Are any display monitors still plugged into the output port of the Intel card? Or are all monitors plugged into the AMD?

On Linux, as the only operating system, you can effectively use two graphics cards for vision science if you really want and need it. If you have a hybrid graphics laptop, Linux might be even the only way to make it usable at all for vision science. And if you want two graphics cards just for regular desktop use without need for precisely controlled visual stimulation timing, it usually just works plug & play.

But if you want to use both graphics cards for visual stimulation, and you want precise visual stimulation timing and control, it requires extra manual setup. And if you want to use a multi-x-screen setup, you’ll have to create the xorg.conf files yourself, as XOrgConfCreator in general can not deal with it - too many weird variations of hardware out there - and will create potentially broken config files. The whole story and instructions in `help HybridGraphics`.

But if this is a regular desktop PC computer, I’d assume you probably would not want to use the old Intel gpu at all for typical bread and butter use cases, and the best course of action would be to simply disable the Intel or Onboard graphics in the EFI firmware settings and then start over with `XOrgConfCreator`.

1. To get your display back, login to a text console (e.g., CTRL+ALT+F3).

2. Make a backup of the XOrg log file and post it. E.g., for the user “username” that was logged in when things went south, the file `/home/username/.local/share/xorg/Xorg.0.log` would be the right one.

3. `rm /etc/X11/xorg.conf.d/90-ptbxorg.conf` or run `XOrgConfSelector` selecting 0 for removing the file - same thing. But **first make a backup of the file and post its content here**.

— Maybe post those files here first to double check? —

1. If you want to go AMD only, reboot the machine, check that things are working again, then reboot into the system EFI setup menu.

2. Somewhere in the many sub-menus there must be a setting that allows to disable the internal graphics (sometimes called iGPU). You’d want “discrete graphics only” or “external graphics” or “dGPU” or some wording like that. Save. Reboot.

3. Now you’d have an AMD only machine, with all monitors connected to the AMD, and XOrgConfCreator and XOrgConfSelector could do their jobs again in this simplified case.

Please respond quickly, technically the paid for support time has already been used up twice so we need to resolve this quickly or further payments would be needed.

That log output - and 90-ptb.xorg.conf generated based on it - looks like your first monitor for Screen 0 and the desktop GUI is plugged into the video output of the Intel onboard graphics chip instead of the AMD. As the XOrgConfCreator generated config file does not allow for use of the Intel chip, AMD only, your experimenter display would be dead.

So maybe simply plugging both monitors into the AMD, then running XOrgConfCreator again, might do the trick already. Or disabling the Intel chip in the EFI firmware settings as I said before.
