[Bug 429369] Re: [i945GM] No screen(s) found after updgrade to karmic alpha 5

[Geir Ove Myhr]

On a Karmic installation, you can add the option to
GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub (after quiet and
splash). If your system is upgraded from Jaunty, it still uses an older
Grub version and you need to edit /boot/grub/menu.lst.

Note that this is a workaround and not a fix, and that the UMS option is
likely to be removed in the future (hopefully only when bugs like this
have been fixed). It would be nice if you could add the ModeDebug option
described above and attach the resulting Xorg.0.log here, since that
will tell us how the monitor detection works with UMS. The problem seems
to be that with KMS the driver thinks that no monitors are attached. It
would be nice if you could also attach the output of dmesg for when you
boot with KMS (i.e. without the i915.modeset=0 option).
