[Problem]
On Ubuntu Intrepid, Fedora Core 9, and OpenSUSE 11.1 Beta 2, all show a blank (black) screen on boot. For this hardware, the problem is seen on Hardy and Gutsy when using -intel; with -i810 it works properly. When the issue is seen, "(EE) intel(0): overrun on pipe B!" is written to the log as well.

[Original Report]
The LiveCD of Intrepid Ibex Beta get a blank (black) screen once it has entered into graphics mode. The same happens with the LiveCD of Hardy and Gutsy.

The computer still works, I can hear the start sound of GDM, and I can log in from GDM, but I just can't see anything on the screen.

With the Feisty's LiveCD the problem does not occur. By viewing the xorg.conf I noticed Feisty uses the i810 driver.

Changing the xorg.conf in Hardy and forcing the use of "i810" driver the problem does not occur. Using the drivers "intel" the problem reoccurs.

In Intrepid Ibex does not work even with the i810 driver.
