main: Could not initialize canvas

[LukeleeTT]

When i use glmark2 on phoronix-test-suite, the error is "could not initialize canvas". And run "glmark2 -d", the error is "couldn't get GL visual config".
When i use glxinfo, the error is "couldn't find RGB GLX visual or fbconfig".
When i run "ps -Af | grep Xorg", print " root 808 783 0 10:23 pts/0 00:00:00 grep Xrog".

What should i do, please.

maybe you should excute "export DISPLAY=:0.0",

maybe you should excute "export DISPLAY=:0.0",

I try it , but the result also prints " Could not initialize canvas".

When i run "ps -Af | grep Xorg", print " root 808 783 0 10:23 pts/0 00:00:00 grep Xrog".

This indicates that Xorg isn't running (you get just your own grep command in the process list), or is the grep output incomplete? Are you running a Wayland compositor with xwayland perhaps: ps -Af | grep Xwayland?

If you are using a Wayland compositor you can also try glmark2-wayland.
