wrong monitor edid data and xrandr won't help remove modes

Post#1 by Chuck » 22 Apr 2024, 12:21

Hello, using porteus 5.01 lxqt x86_64. Into monitor setting i have some video modes which it doesn't support and activating them means out of sync. That's a problem for me because i'm using wine for old games which lowers the resolution and chooses an unsupported resfresh rate (i could use virtual desktop but the window will be small). That's the output form xrandr:

Code: Select all

xrandr

DVI-I-1 disconnected (normal left inverted right x axis y axis)
HDMI-1 disconnected (normal left inverted right x axis y axis)
Minimum 320x200 but 320x180 is available? However I've tried to verify which video modes are unsupported and i would like to remove them but no way of doing it:

Code: Select all

xrandr --rmmode 1024x768_75.05
xrandr: cannot find mode "1024x768_75.05"

xrandr --delmode VGA-1 1024x768_75.05
xrandr: cannot find mode "1024x768_75.05"
What am i doing wrong? Is there a file where this modes are stored to just delete them? Maybe i could solve creating a xorg.conf file?
