My guess is that a necessary package is missing. Make sure that the
libxcb and libxcb-keysyms packages are installed.

Hello,
I am at my wits end.
I have a Debian 12 that is running VirtualGL as a server.
I have a debian 12 that is running VirtualGL as a client (Only
installed, not configured)
On the server:
I erased my xorg.conf and ran first : nvidia-xconfig
Then ran :
service gdm3 stop
/opt/VirtualGL/bin/vglserver_config option 1, Y to everthing.
service gdm3 start
And then just for safeteys sake I did a reboot.
SSH to server from client with -X
Tested according to documentation, section 6.2.1
Everything looks great.
Now....I want to test vglrun
$ vglrun xclock
[VGL] NOTICE: Automatically setting VGL_CLIENT environment variable to
[VGL] 100.101.0.58, the IP address of your SSH client.
[VGL] ERROR: VirtualGL attempted to load the real
[VGL] xcb_poll_for_event function and got the fake one instead.
[VGL] Something is terribly wrong. Aborting before chaos ensues.
And here I am stuck.
I've tried setting the full path to libGL.so in LD_PRELOAD, tried
setting the path with LD_LIBRARY_PATH.
Then out of desperation, tried using VGL_PRELOAD and VGL_LIBRARY_PATH.
Still the same error message.
Whatever I do, I still end up with the same error that it takes the
"fake" libGL.so.
Note that nvidia is using the follwing libGL.so:
$ ls -l /usr/lib/x86_64-linux-gnu/libGL.so
lrwxrwxrwx 1 root root 48 3 jan 2023
/usr/lib/x86_64-linux-gnu/libGL.so ->
/etc/alternatives/glx--libGL.so-x86_64-linux-gnu
$ ls -l /etc/alternatives/glx--libGL.so-x86_64-linux-gnu
lrwxrwxrwx 1 root root 48 3 jan 2023
/etc/alternatives/glx--libGL.so-x86_64-linux-gnu ->
/usr/lib/mesa-diverted/x86_64-linux-gnu/libGL.so
So can anyone give an idea what I should check next?
