Intel 915GM video mode switching leaves laptop with black screen with
both native and VESA drivers.
Old description:
The Intel driver bundled with Beta 2 works fine, if sluggishly and with
some graphical glitches (due probably more to the age of the chip), but
using a screen resolution besides the native 1024x768 leaves it with a
blank screen--usually seen when using programs in full screen. In an
effort to remedy this, I switched to the VESA driver with the keyboard
shortcut, and it left me with the same blank screen. Trying to invoke the
boot options menu leaves me with another blank screen. I can't get past
this.

Comment:
There is some confusion here. The shift-control-alt-escape does not switch
to the VESA driver. It just switches to a safe video mode (probably
1024x768 or 800x600 with 16bit or 256 colors? I could not find where this
is implemented in the code...).
The "failsafe graphics driver" option in the boot menu does switch to the
VESA driver, which is a completely different thing.
If you're having graphics glitches to start with, and both of the drivers
fail in some way, it sounds a bit worrying. Are you sure the hardware is
ok? Does it work with other OS?
For further investigation, please provide syslogs for the following
situations (make sure to delete the syslog from /system/var/log/syslog
between each test to have results for just oen boot in each):
- Booting with the failsafe graphics driver enabled
- Booting normally, then changing the video mode
