Red Hat Bugzilla – Bug 401801
ATI mobility radeon black screen and hang
Last modified: 2008-03-30 22:44:07 EDT
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. xorg-x11-drv-ati-6.7.196-1.fc8 How reproducible: Always 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.

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"

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.
Well, I've successfully circumvented the problem (as above) so I'm not interested in pursuing this problem. Feel free to close it "wontfix".
