I have a docker environment with VNC where I want to do simulations. the simulation environment runs fine but the graoh output was missing. So i tested glxgears and it seems that glxgears only works when running as sudo. If i run it as normal user the result is:
X Error of failed request: BadShmSeg (invalid shared segment parameter)
Major opcode of failed request: 130 (MIT-SHM)
Minor opcode of failed request: 3 (X_ShmPutImage)
Segment id in failed request: 0x1a00005
Serial number of failed request: 43
Current serial number in output stream: 44
I tried the following
- adding the user to the sudo and video group,
- running the docker with --ipc=host
- comparing the shared memory between the 2 users
- running the glxgears with LIBGL_ALWAYS_INDIRECT=1
- reinstall mesa-utils (was already latest)
- compared the env variables between sudo and normal user
- test glxinfo (runs without problem)
i can not run my simulation (ros2 + gazebo) in sudo. Does anyone have another idea what i could try?
result of ipcs -l
