Unable to get good resolution on monitor

Post by jagga13 » 2018/04/24 15:26:08


I have a CentOS 6.9 workstation with a NVIDIA video card and I would prefer not to use the NVIDIA provided driver for. So, I have the nouveau driver installed. However, with this setup my screen resolution is very low on a LG monitor. Here is what xrandr reports:

Code: Select all

$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
   1024x768      61.00* 
   800x600       61.00  
   640x480       60.00  
Also, my xorg.conf seems to be very limited:

Code: Select all

# cat /etc/X11/xorg.conf
Section "Device"
	Identifier "Videocard0"
	Driver "vesa"

Driver "vesa"
Why the vesa driver? That only allows you access to video modes that are supported by your BIOS. I'd try moving that xorg.conf out of the way as 98% of machines don't require one any more, it's all autodetected.

Is xorg-x11-drv-nouveau installed?
