The login screen uses the wrong resolution and it's in the wrong position as usual. I connected over VNC to login. Strangely now there is no split screen anymore (I checked and I'm using 3.2.0-drm-intel-fixes+) the screen is black and the resolution is 1024x768 (I can see from VNC) xrandr --output HDMI2 --mode 1024x768 --rate 60.0 (as expected no change since it's the actual res) xrandr --output HDMI2 --mode 1280x720 --rate 60.0 (the TV does something, but then goes back to black resolution is correct from VNC) xrandr --output HDMI2 --mode 1280x720 --rate 50.0 (the TV does something, but then goes back to black resolution is correct from VNC) xrandr --output HDMI2 --mode 800x600 --rate 60.3 (the TV does something, but then goes back to black resolution is correct from VNC) xrandr --output HDMI2 --mode 800x600 --rate 60.3 (the TV does something, but then goes back to black resolution is correct from VNC) xrandr --output HDMI2 --mode 720x480 --rate 59.9 (the TV does something, but then goes back to black resolution is correct from VNC) xrandr --output HDMI2 --mode 640x480 --rate 59.9 (the TV does something, but then goes back to black resolution is correct from VNC) xrandr --output HDMI2 --mode 640x480 --rate 60.0 (the TV does something, but then goes back to black resolution is correct from VNC) I didn't save any dump cause you requested one where HDMI was working and it never did. Any idea? My question is: why I don't even see the split screen anymore and just the black screen? So, just to test, I run with 3.0.0-15-generic-pae and indeed I can see the split screen again. Also, the login screen is 1024x768 (split) rather than 1280x720 (when I run 3.2.0-drm-intel-fixes+) In 3.0.0-15-generic-pae, I can see the split screen but xrandr -q reports way less combinations (1024x768 at 60.0, 800x600 at 60.3, 640x480 at 60). I tried all three and they all "work" in split screen w/o flickering. The TV goes never "black". > It just needs to be a HDMI-only configuration that works. So if I understand your request correctly, I don't have such situation with only HDMI. AGAIN, as soon as I connect the VGA cable the TV is not in split screen anymore and I can see just fine. But you already have this test from the previous time so I won't take any log. > > Test with the i915 driver (i.e. no nomodeset on the kernel cmdline), > if you want you can try both VGA cable only and VGA/HDMI but it > shouldn't matter. xrandr -q output shows only 55.4 and 60.0 for this > resolution, so I think it doesn't make sense to test anything else. TEST-12 ======== VGA and HDMI connected. TV set on VGA input. Reboot. The login screen is black. I connected over VNC to login (login screen is 1024x768) xrandr --output VGA1 --mode 1024x768 --rate 54.4 (nothing changes, as expected) xrandr --output VGA1 --mode 1024x768 --rate 60.0 bingo. I can see the screen with quite a bit of overscan top and bottom (exactly as I usually saw it over VGA from XP) I also tried the same test with only VGA cable connected and it works the same way. xrandr --output VGA1 --mode 800x600 --rate 60.3 also works like in windows, with overscan. I attached logs from 1024x768. So, to conclude, I think we achieved feature parity over VGA. It's just a matter of choosing the right refresh rate... Do you have any idea about the next step for HDMI? thank you, alfonso
