Public bug reported:
Binary package hint: linux-image-2.6.26-5-generic
With Intrepid Alpha 4, after ubuntu boots, display goes blank. I can see
the boot progress screen. However, when it switches to X, the display
goes blank. Ctrl+Alt+F1 does not show text-mode either. With X, the
display is blank, but there is some signal. However, in text mode (with
Ctrl+Alt+F1), the monitor says no signal.
This is on Lenovo Thinkcentre A59, which comes with intel Q35 integrated
graphics:

Monitor is a Lenovo ThinkVision 19" wide-screen with a native resolution
of 1440x900, connected through VGA output.
Finally, the workaround is to pass 'vga=771' to the kernel parameters.
In this case, everything works properly - the right resolution is chosen
and switching to text mode and back works as expected.
