Hi,
I am trying to add a custom resolution to my laptop. I followed this which is the standard ‘cvt’, ‘xrandr --newmode’ and ‘xrandr --addmode’. I’ve successfully added the resolution, but when I try to apply it, using ‘xrandr --output’ or using the ‘Display Resolution’ app, my screen just goes blank/black. No custom resolutions seem to work. I have done a lot of searching to try solve this issue, but I am at a loss.
My laptop is a ‘HUAWEI MateBook D14’ (kpl-w0x), which has an ‘AMD Radeon RX Vega 8’.
This is the output of ‘xrandr --verbose’

When I try to set the output with ‘xrandr’ with ‘–verbose’ I get this
