Hmm, often with these kind of blank-on-X-startup bugs it is because your video is getting sent to the wrong output device.
Unfortunately I can't tell from your logs which output devices you have, but usually you test this by adding something like this to xorg.conf: Section "Monitor" * Identifier "LVDS" Option "Ignore" "True" EndSection Usually you can see what output devices are available by running 'xrandr'; this also indicates which is turned on. You may be able to locate this info in your dmesg. Please try starting up in the failed configuration, then ssh in and collect the following: * `dmesg > dmesg.txt` * `sudo dmidecode > dmi.txt` * `DISPLAY=:0 xrandr --verbose > xrandr.txt` Then attach those three files. Also if you find that by switching off one of the outputs solves the issue, let us know that too and we may be able to put in a quirk for your hardware. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Incomplete -- [G35] blank screen after X startup with HDMI connected to a TV https://bugs.launchpad.net/bugs/392737 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
