Description Bob Raitz 2009-02-04 21:10:20 UTC
Latest working kernel version:2.6.27.12
Earliest failing kernel version:2.6.28
Distribution: Gentoo
Hardware Environment: x86
Software Environment: GNU/Linux
Problem Description: After updating to GEM through portage while running 2.6.28.3, laptop with i830 video chip has video distortion with KDE-3.5.10. Machine also locks coming out of KDE. The machine still works as far as the network is concerned, ie ssh and nfs, but will not respond to mouse or keyboard. Pressing the power button trips acpid, which shuts off the machine.

Steps to reproduce: Boot with 2.6.28.3 kernel. Machine shows distortion in KDE-3.5.10, and locks coming out of it.
Comment 1 Bob Raitz 2009-02-04 21:18:11 UTC
The machine in question originally would not start KDE if it was running a 2.6.28 kernel. After GEM became available, upgrading to it allowed a machine with an io915 video chip to work with 2.6.28.3. While the machine in question will start a KDE session, the video is extremely distorted (pictures to follow). The video locks up coming out of KDE. Information on machine to follow.

Thanks.

Comment 13 Bob Raitz 2009-02-04 21:36:35 UTC
Just to make absolutely clear, without GEM, the machine in question will not start X. With GEM, I get the problem described here. I have another machine that, once upgraded to GEM, now runs 2.6.28.3 properly, but would not beforehand.

Any other info needed? Just ask.

Wow, that was fast. Thanks.
Comment 15 Daniel Moos 2009-02-14 15:43:15 UTC
Got similar errors with .28 here and the patches for .29-rc1 or -rc2 fixed them.
Comment 16 Bob Raitz 2009-02-14 23:33:29 UTC
I recently grabbed 2.6.29-rc3-zen1, and while I was able to get X to start, the initial KDE-3.5.x splash screen is all messed up. 

After that, I may or may not be able to exit X. If I dare to try to go for a second X run, X will start, but the WM (either KDE-3.5.10 or XFCE-4.4) will not start. The mouse moves, but even Skinny Elephants can't get it back. 

I can still access the machine via ssh and nfs, and I can shut it down with one press of the power button...thank the goddess for acpid. I guess you could say it's a step ahead, but I'd prefer something that can come out of and into X as I choose.
Comment 17 Bob Raitz 2009-02-23 22:26:59 UTC
The bug remains with .29 rc kernels. So, yes, this is still an active bug.
Comment 18 Bob Raitz 2009-03-03 14:54:48 UTC
Still remains.
Comment 19 Daniel Drake 2009-03-14 16:56:22 UTC
So is there any known working situation? What do you mean by "updating to GEM"?

Moving to mesa-7.2, and libdrm-2.4.5, which contain code for GEM. In other words, where it used to say "Failed to initialize TTM. Falling back to classic," it then said "Failed to intitialize GEM. Falling back to classic."

Known working situation, as in, does it work at all with 2.6.28.x. No, this machine will not work that way. The machine in question simply will not work properly under X with a .28 kernel. It is currently working with 2.6.27.19.

Comment 22 Bob Raitz 2009-04-02 18:53:39 UTC
The machine that was having this issue has died. Therefore, unless someone else wishes to champion this cause, I say let the bug die with the machine.
Comment 23 Jesse Barnes 2009-12-02 19:45:42 UTC
Sorry about that, but at least we have one less i830 machine to worry about :/
