The problme has been described clearly there -- whenever you close the lid
(and my guess is that the system went to the suspended mode) and open it up
again, the screen was garbled to the extend that even using ctrl-alt-backspce
to kill the server won't help.  Ctrl-alt-F1 cannot get to alternative console
either.  The only way out is to power cycle the system.  (It's using the ATI
Radeon M7 with 32MB video ram.)

The /var/log/messages also shows:

I wonder if anybody has a solution to this?

Thanks in advance and have a good day.

Kevin,

Thank you very much for the workaround.  It does the trick:

1) Use CTRL-ALT-F1 to go to alternative console mode,
2) Close the lid and open it up again,
3) Use CTRL-ATL-F7 to return to the X window.

Now the question is why we don't have this problem running
Windows XP.  Is the problem with the Radeon M7 driver under
XFree86?  Or the problem is with BIOS?  If it's the later,
I might bug Dell for a fix.

Have a wonderful day.

Bruce


Sigh! This really needs to be a FAQ. IF only there was a fix. But
there is a (messy) workaround. But it's lots better than a reboot.

Russ Fink posted the following note before:

	Section Device
	  Identifier ATI|Rage Mobility M3 AGP 2x
	  BoardName Unknown
	  Driver r128
	  Option Display BIOS
	EndSection

The part that is the fix is the Option Display BIOS part.
This tells the X server to consult the BIOS and use whatever settings
it is using for the display.

I put the Option line in /etc/X11/XF86Config (Red Hat 8.0) and
the screen doesn't garble anymore when the lid is closed and
open again.  Hope this helps.
