glxinfo shows BadAlloc (insufficient resources for operation)

**nomadicsun** · August 10th, 2024

Hi folks,

I was trying to install gpu drivers following the steps in Prerequisites for Linux NICE DCV servers - NICE DCV (amazonaws.cn),

After installing the nvidia gpu driver (nvidia-driver-535) in my ubuntu 20.04 LTS server,

I tried to run the glxinfo which can be installed via 'apt install mesa-utils', but it shows as below,

Code:

root@dcvserver03:~/bin# glxinfo
name of display: :0
X Error of failed request:  BadAlloc (insufficient resources for operation)
  Major opcode of failed request:  151 (GLX)
  Minor opcode of failed request:  5 (X_GLXMakeCurrent)
  Serial number of failed request:  0
  Current serial number in output stream:  50

and the funny thing is, if i export DISPLAY=:1 and 'startx', then run glxinfo, it show as below,

Code:

root@dcvserver03:~/bin# export DISPLAY=:1
root@dcvserver03:~/bin# startx &
[1] 52270
root@dcvserver03:~/bin#
root@dcvserver03:~/bin# glxinfo |less
name of display: :1
display: :1  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
...

and for the display :0, it is the Xorg process started by gdm3.

and i tried to gdb glxinfo, and it exit at this line 460 in file mesa-demos-8.4.0/src/xdemos/glxinfo.c, if (glXMakeCurrent(dpy, win, ctx))

i am a newbie for the linux graphical programming, can anyone help to direct what's the possible reason? Thanks very much!

eh, i'd to know the reason why glxinfo show the error for DISPLAY :0.

I compiled the glxinfo command from source code which can be download from src/xdemos/glxinfo.c · main · Mesa / demos · GitLab, but still same error.
I guess it may related with the Xorg session which is started by gdm3 service, but don't know how to investigate further, can you advice? Thanks!
