Description tengel 2006-06-29 06:48:22 UTC
Description of problem:
Waking from suspend on a T43 Thinkpad (2687D3U) results in screen corruption.
The screen is black with horizontal white lines immediately, locked up. Have to
press power button to initiate a low-level complete shutdown to reboot.

Version-Release number of selected component (if applicable):
kernel-2.6.17-1.2139_FC5 i686

How reproducible:
Always with this kernel.

Steps to Reproduce:
1. install/boot to kernel-2.6.17-1.2139_FC5, runlevel 5
2. (F) menu -> Suspend
3. Press power button to wake laptop
Actual results:
Screen is a solid, slightly off-horizontal set of white lines on a black screen,
no visible pattern (image) it may have come from.

Expected results:
Normal resume from suspend screen as with previous kernels

Additional info:
- Previous kernel kernel-2.6.16-1.2133_FC5, and all other kernels from FC5 so
far, have worked just fine. Appears to be something new with this kernel.

- CTL+ALT+BKSP (and others) nonfunctional to try and resolve the problem; must
press the power button to initiate a lowlevel shutdown, which works correctly at

- all updates applied as of 2006-06-28 23:30 PST

Hardwaare modules are all stock from FC5 RPMs, nothing custom. ATI Radeon X300
video in native 1400x1050 mode. Very vanilla install, has been been A-OK prior
to this kernel - currently booted to kernel-2.6.16-1.2133_FC5 and operating as

Comment 1 Paul W. Frields 2006-06-30 14:32:38 UTC
This is very likely the same situation I had in #196547 (I have the *exact* same
ThinkPad T43, model and trimline).  I don't think DRI works yet with the Radeon
X300.  Try commenting out the following line in the "Module" section of your
/etc/X11/xorg.conf file:

  # Load "dri"

If that fixes your problem, you can close this bug as a DUPLICATE of #196547.

Comment 2 Paul W. Frields 2006-06-30 14:34:33 UTC
Sorry, I had no intention of closing this unilaterally and just mis-moused.  I'm
reopening so the reporter can test the fix.

Comment 3 tengel 2006-06-30 18:22:45 UTC
I'll close this as a duplicate, thanks for the link to the other bug. My caveat
to this (disabling dri) is that the system has been working perfectly for a long
time  - with every other kernel and dri enabled - until this newest kernel was

I still feel something has broken in the kernel in 2139, whether or not anyone
decides to investigate and fix.
