[SOLVED] xrandr Failed to get size of gamma for output and Configure crtc 0 failed

kiptroti · 04-10-2018, 11:13 PM

I am running Ubuntu with a pretty cheap monitor and a pretty cheap graphics card. Ever since I installed Linux (all other threads were errors after new drivers were installed) the resolution set by xrandr has been 1024x768 when the monitor is capable of 1920x1080. I tried the following steps to try to fix it, but they didn't work:

Code:

[~]$ cvt 1920 1080 60
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
[~]$ xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr: Failed to get size of gamma for output default
X Error of failed request:  BadName (named color or font does not exist)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  16 (RRCreateMode)
  Serial number of failed request:  19
  Current serial number in output stream:  19
[~]$ xrandr --addmode default 1920x1080_60.00
xrandr: Failed to get size of gamma for output default

Output of xrandr:

Code:

[~]$ xrandr                 
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1920 x 1080
default connected 1024x768+0+0 0mm x 0mm
   1024x768      76.00* 
   1920x1080_60.00  59.96  
   1920x1080_30.00  29.95

Trying to change the resolution:

Code:

[~]$ xrandr -s 1920x1080
Failed to change the screen configuration!

the errors (EE) in the Xorg.0.log are pretty clear.
now please post the output of:

Code:

lspci -k | grep -iEA5 'vga|display|3d'

Sorry for not replying, that was my first LQ post and I couldn't figure out how to get back to the thread I started. I resolved the problem myself by uninstalling Ubuntu and installing Manjaro instead.
