Hi all

Any update on this? I have hacked the way the modelines are probed and
now it works on my screens, but of course there is no warranty that it
will work with other screens :


I plan to complete this task in the next two weeks. Really sorry for the delay.

Thanks!

The pll does not seem to be reconfigured if I set the same resolution
again and again.

So I am trying to go between two faulty resolutions:

while true; do xrandr --output HDMI-1 --mode 1600x1000 --rate 60.01 ;
sleep 5; xrandr --output HDMI-1 --mode 1680x1050 --rate 59.97; sleep 5
; done

and after 10 minutes or so I havent seen anything on the screen
besides some blinks.

Thanks!
