Ask Ubuntu Asked by vajad57 on February 22, 2021
I have installed Ubuntu 20.10. I have a HP Elitebook 8570w with Nvidia Quadro k1000m graphics card.
I can’t select 1920 x 1080 resolution for my external screen
I have tried:
xrandr --newmode "1920x1080" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
xrandr --addmode VGA-1 1920x1080
xrandr --output VGA-1 --mode 1920x1080
But I get this error when I run the second command
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 47
Current serial number in output stream: 48
