Ok Daniel, I also tested drm-intel-fixes branch (to check if I could get 1024x768p without flickering) I followed your instructions: - First checkout Keith's kernel tree: - git clone git://git.kernel.org/pub/scm/linux/kernel/git/keithp/linux.git - Then checkout the drm-intel-fixes branch with - git checkout -t origin/drm-intel-fixes - Confirm with - git branch - that you're indeed on the -fixes branch. Then do whatever your distor - howto tells you to compile a kernel from sources. after reboot I see yet an other behavior. LightDM shows an odd resolution. Not flickering but oddly placed and definitely not usable. After login the screen goes black (interestingly, not blue like when I try 1920x1080i) I logged in with VNC and tried to switch to 1024x768p with xrandr: xrandr --newmode "1024x768_01" 65.00 1024 1048 1184 1344 768 771 777 806 -hsync -vsync xrandr --addmode HDMI2 "1024x768_01" xrandr --output HDMI2 --mode "1024x768_01" but nothing changes. Recap: original kernel: two half screens flickering latest drm-intel-fixes branch: black screen attached dmesg.output and Xorg.0.log thank you, alfonso -------------- next part -------------- A non-text attachment was scrubbed...
