I am trying to add a resolution of 800x600
xrandr --newmode "800x600_60.00" 38.25 800 832 912 1024 600 603 607 624 -hsync +vsync
xrandr --addmode default "800x600_60.00"
xrandr --output default --mode "800x600_60.00"
After that last command I receive:
Quotexrandr: Configure crtc 0 failed
Any idea about how to use that resolution?
Thx!
Update 1: change_display.sh returns "Unknown boot device". (solved)
Update 2: I can see the video output while booting (800x600 60Hz).
Update 3: How can I apply the same configuration used at boot time?
(solved adding params to bootargs)
