graphic hardware vs graphic software

[tom_d]

lspci -nn | grep VGA
tells me the correct card

glxinfo | grep vendor
tells me "Error: unable to open display"

what's the cli command to tell me what driver it's trying to use?

Re: graphic hardware vs graphic software

Maybe:

grep "driver" /var/log/Xorg.0.log

Looking errors:

grep "EE" /var/log/Xorg.0.log

warnings:

grep "WW" /var/log/Xorg.0.log

The "Xorg.0.log" is a log file for the X Windowing Server.
