Dear DRC / VGL forum,
VGL+TurboVNC has been a fantastic solution for me. Thank you for all of your continuing development efforts.
I have a nagging problem I'd like to debug, and hope you can help. First some info about my server:
- Ubuntu 16.04 LTS with LXDE
- NVIDIA Quadra k620 graphics
- latest VGL, TurboVNC and libjpeg
- also hosts an X2Go install
- has a physical monitor attached for occasional console use
- hosts 2-10 users at a time
When I boot the system, I can create a VNC session and run "vglrun glxgears" without any trouble. I can also log in at the monitor. But after some time / use, I eventually run into several problems:
- vglrun glxgears fails in my session with the output "[VGL] ERROR: OpenGL error 0x0502 [VGL] ERROR: in readPixels-- [VGL] 480: Could not Read Pixels"
- Other users report the error "Invalid MIT-MAGIC-COOKIE-1 key[VGL] ERROR: Could not open display :0."
- Windows in certain applications become invisible. For example, LX terminal windows show in the dock but when restored show no content. This is the case even though the LX terminal windows are not launched using vglrun. By contrast, third-party console windows continue to display properly.
After encountering one of the above errors, it seems the only way to fix it is to reboot the system, although this is often difficult with a number of users having open sessions. That has slowed down my troubleshooting.
I've run vglserver_config a number of times and read the documentation carefully, but this hasn't seemed to help. The fact that it works properly *at first* suggests to me that it's probably configured right but that some other process is mucking things up. I have a couple of ideas:
- Could logging on and then off using an attached monitor while sessions are open be causing problems (is VGL supposed to be strictly headless)?
- Could there be problems of interoperability with X2Go use on the same system?
- Could it be some kind of permissions problem? I did check that all users are in the vglusers group.
Any thoughts or suggestions would be very welcome! Below I've pasted my xorg file, as well as glxinfo output from displays 0 and 1 while the system is in its non-working state (the DISPLAY variable shows :1.0). The error messages in glxinfo for display 1 start to appear once the problems begin; before then it looks more like the info from display 0.
Thanks in advance for any help,
Jordan

VGL servers do not have to be headless, but logging in and logging out of the 3D X server could cause problems in the following ways:
1. In many cases, logging in at the server console causes the permissions on the framebuffer device to be reassigned to whichever account is logging in. vglserver_config is supposed to modify the system appropriately to ensure that members of the vglusers group or all local users (depending on which option you selected when running vglserver_config) retain permission to the framebuffer device, but perhaps this is not working on your system for some reason. The OpenGL 0x502 error could be caused by inappropriate access to the framebuffer device. If you can reproduce the error reliably, double check the framebuffer device permissions when it occurs. If they are somehow being set incorrectly, then I can investigate that.
2. When you log in and back out of the 3D X server, this will change the cookie that VGL uses to access the 3D X server (/etc/opt/VirtualGL/vgl_xauth_key). Since that cookie is normally merged into a user’s ~/.Xauthority file when vglrun is executed, it’s possible that logging in and back out of the 3D X server could cause 3D applications that are already running to lose access to the 3D X server. VGL makes a connection to the 3D X server only when it needs to— generally whenever the application makes a GLX call for the first time. It seems unlikely that you would be logging in to the 3D X server during the brief period between the application starting and VGL making the necessary connection to the 3D X server, but perhaps VGL is unable to make that connection while you are logged in. That is also something I can investigate.
As far as the LXDE problem, that sounds like more of a TurboVNC problem. The first thing I’d try to remedy that issue is to start the TurboVNC Server session with /opt/TurboVNC/bin/vncserver -composite. If that works, I’ll make a note of it in the TurboVNC Window Manager Compatibility Report. If not, I’ll have to investigate further.

Did you try my suggestions? Even if they worked, I need to know so I can document the issue.
