Ok, results from git/torvalds/linux.git plus Peter's patch. The system boots in 1024x768 with the flickering problem. Then I manually try to switch to interlaced. I saw from Xorg.0.log (attached) the following two modelines so I tried both: #Modeline 1920x1080ix0.0 74.25 1920 2448 2492 2640 1080 1084 1094 1125 interlace +hsync +vsync (28.1 kHz) #Modeline 1920x1080ix0.0 74.25 1920 2008 2052 2200 1080 1084 1094 1125 interlace +hsync +vsync (33.8 kHz) xrandr --newmode "1920x1080i_01" 74.25 1920 2448 2492 2640 1080 1084 1094 1125 interlace +hsync +vsync xrandr --addmode HDMI2 "1920x1080i_01" xrandr --output HDMI2 --mode "1920x1080i_01" xrandr --newmode "1920x1080i_02" 74.25 1920 2008 2052 2200 1080 1084 1094 1125 interlace +hsync +vsync xrandr --addmode HDMI2 "1920x1080i_02" xrandr --output HDMI2 --mode "1920x1080i_02" in both cases the resolution change takes effect (I can see that cause I use VNC) but the screen goes blue. I also attached output dmesg with drm.debug=0xe any idea? thank you, alfonso On Thu, Jan 19, 2012 at 8:05 AM, Alfonso Fiore <alfonso.fiore at gmail.com> wrote: > On Wed, Jan 18, 2012 at 9:12 PM, Daniel Vetter <daniel at ffwll.ch> wrote: > >> Yep, that's correct.
