Description Robert Peterson 2007-11-27 16:28:35 EST
Description of problem:
This may turn out to be the same as bug #399021.
I upgraded my laptop from F7 to F8.  X worked perfectly under F7,
but under F8, I just get a black screen (i.e. not backlight) and
the system becomes unresponsive.  I can't exit X.

If I boot at runlevel 3, then do startx, I get a screen that is
hosed, but the backlight is on.  I can see the "X" and move it
around with my mouse, but the top tenth of the screen is filled
with lots of blue and red blotches.  About a third of the way down
the screen, there's another very light streak of indiscernible
graphics.  I never get the gnome screen.
I can ssh into the system.  I tried killing X, but it didn't die.
It's stuck at 100% cpu utilization.

Version-Release number of selected component (if applicable):
Latest F8 updates.

How reproducible:

Steps to Reproduce:
1. Turn on my Sharp Actius MP30
2. Watch it go bye-bye.
Actual results:
Black screen, unresponsive

Expected results:
X should work normally.

Additional info:
My xorg.conf:

Comment 3 Robert Peterson 2007-11-27 17:05:19 EST
I added:

Option      "bustype" "pci"

to the Device section, but it had no effect.
Under the direction of David Airlie, I added:

Option      "dri" "false"

to the Device section and it works okay now.  So apparently the problem
is in dri.

It works okay with "bustype" "PCI" so apparently case matters.
It also works if I take out "bustype" "PCI" and "dri" "false"
(dri enabled) but add this:
Option      "AGPMode" "1"

Comment 7 Dave Airlie 2008-03-30 21:55:45 EDT
not much we can do about this, try the latest updates testing branch it defaults
to using a low AGP rate..

AGP is just plain badly implemented in a lot of hardware.
Comment 8 Robert Peterson 2008-03-30 22:44:07 EDT
Well, I've successfully circumvented the problem (as above) so I'm not
interested in pursuing this problem.  Feel free to close it "wontfix".
