Display resolution issues.

[nrich588]

Hello everyone, I recently installed CentOS on a new machine I am using for a small test server, however I am running into issues with the display resolution.

Firstly, the only resolution available in the settings is 1024x768 (display is 1920x1080).

Second, when entering the xrandr command, this is the output I receive:

Code: Select all

[root@localhost ~]# xrandr

xrandr: Failed to get size of gamma for output default

Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768

default connected primary 1024x768+0+0 0mm x 0mm

  1024x768      76.00*

  1920x1080_60.00 (0x2b8) 173.000MHz -HSync +VSync

        h: width  1920 start 2048 end 2248 total 2576 skew    0 clock  67.16KHz

        v: height 1080 start 1083 end 1088 total 1120          clock  59.96Hz

Wasn't sure how to fix this, I don't think it is properly detecting my display (Display Port). I apologize if I am short on info, this is my first Linux venture.

Most likely you are missing a driver for your video card. What's the output from lspci -nn | grep -i vga ?

Sir I have same issue. I checked I don't miss any driver for my video card.
