If any of them work correctly (instead > of the cut-in-half or tiny screen), that might be interesting to know. Hi, more tests with the drm-intel-fixes and no "nomoreset". I boot (as usual) just with HDMI cable. The PC boots in that weird way (I sent photos today) and then when I login the screen is split. Interestingly, trying to connect the same screen over VGA (while running and already connected over HDMI) makes X hang BUT it also changes the way X shows: full screen, no flicker (i.e. as it should). when I restart X (sudo restart lightdm) I have a FANTASTIC PERFECT SCREEN! :) :) $ xrandr -q Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192 VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 400mm x 300mm 1024x768 60.0* 800x600 60.3 56.2 848x480 60.0 640x480 59.9 HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) HDMI2 connected 1024x768+0+0 (normal left inverted right x axis y axis) 640mm x 360mm 1280x720 50.0 60.0 1024x768 60.0* 800x600 60.3 720x576 50.0 720x480 59.9 59.9 640x480 60.0 59.9 HDMI3 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) DP3 disconnected (normal left inverted right x axis y axis) 2nd test: I reboot again just with HDMI connected. LightDM still looking "weird" (like today's picture) and after login still split screen. When I plug the VGA cable (over DVI-I) the screen goes black (not blue). If I restart X the screen goes blue and then black and from VNC I can see it's still 1024x768 (so why black?). xrandr -q didn't change. if I turn the TV over the VGA signal I get a very weird full green image flickering very fast. 3rd test: I reboot again with both cables connected (VGA over DVI-I and HDMI). LightDM and X looks PERFECT! :) Both login screen and session looks just like they should. 4rd test: same as previous but I want to check if it will happen the same way. Yes, again, LightDM and X looks PERFECT! Interestingly, if on the TV I switch to VGA input I see a black screen... I attach the logs for this session, maybe you can figure out how to have this behavior without VGA cable plugged in! about testing different resolutions. If I test them from THIS situation (e.g. both cables connected from boot) I report the following: xrandr --output HDMI2 --mode 1280x720 ===> I get quite a bit overscan but the picture is stable xrandr --output HDMI2 --mode 1024x768 ===> fits like a glove. Not a pixel of overscan. Never had such a good fit over VGA with my laptop and XP. xrandr --output HDMI2 --mode 800x600 ===> this is quite hard to explain. The "real" screen is 1024x768 but I can only see 800x600 but X seems to know what's going on because it creates two sets of controls, one aligned at 800, one aligned at 1024. I guess the two screenshots will help you (one of the TV screen and then a screen grab). > Maybe also attach the raw edid, you can find it in /sys/class/drm/*/edid > for your TV. about my edid info: $ find /sys/ | grep edid /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-VGA-1/edid /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-1/edid /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-DP-1/edid /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-2/edid /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-3/edid /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-DP-2/edid /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-DP-3/edid Interestingly enough the EDID I get from VGA is 256 bytes while EDID from HDMI is 128 bytes... They are both in the logs. hope this helps you help me, alfonso -------------- next part -------------- A non-text attachment was scrubbed...
