Can't set a new resolution on Ubuntu 20.04
By Sarah Rodriguez •
Okay, I've been using my laptop connected with a external screen which is 2560x1080, try to add the new resolution and set up. But always return xrandr: Configure crtc 1 failed. Also checked my CPU max resolution on HDMI and it's 4096 x 2304@60Hz, don't know what else to do.
The commands I use was: xrandr --output HDMI-1 --crtc 1 --mode 2560x1080_60.00, xrandr --output HDMI-1 --crtc 2 --mode 2560x1080_60.00, xrandr --output HDMI-1 --mode 2560x1080_60.00 but always return failed.
Its weird cause it shows 2560x1080 in the GUI, but still don't set for the 2560x1080, always reverse.Resolutions options
Reset to default
