This could be fixed by adding some lines to xorg.conf, but because we are trying to move away from manually editing the xorg.conf file, another way should be preferred. One way is to use xrandr (not quite the same as lxrandr) to set the external monitor resolution upon gdm startup.
In order to do this, edit the /etc/gdm/Init/Default file (a script run @ the start of gdm), and insert a line similar to the following: xrandr --output VGA --auto Where "VGA" is the output name of your external monitor (can be found by looking at the output of "xrandr -q"). For lazy people, attached is a patch file that inserts the appropriate line into the file. To apply it: sudo patch -d /etc/gdm/Init/ < gdm_init_patch.diff Mike ** Attachment added: "Sets the external monitor screen resolution with xrandr at gdm startup." http://launchpadlibrarian.net/19576910/gdm_init_patch.diff -- [Intrepid] Regression: wrong GDM resolution when using external display on i945 https://bugs.launchpad.net/bugs/281486 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
