xorg.conf
With the exception of NoAccel, this is the output of X -configure.
Also, I forgot to mention before, X -configure works and returns control to the console properly, but xorgcfg puts up garbage and there's no way to get control back.

Xorg.0.log from a running server with NoAccel
When the server is stopped, only two more lines are added about the keyboard and mouse modules being unloaded.

Xorg.0.log from a running (broken) server without NoAccel
This log is from a running server with garbage displayed on the screen.
Note that the server tries restarting itself several times (producing garbage each time), and this is the *last* log it produces. I haven't yet managed to get the first log it produces.
Also, I forgot to mention, I'm using Gentoo linux, and these are the gentoo packages.
Server works fine with Option "AccelMethod" "XAA" (I guess this is why I never had a problem with 2.1.*) Also, 2.5.1 hasn't fixed it (not that the changelog indicated it would). What's the kernel version? I've tested recent kernel 2.6.28-rc8 with other git masters of gfx components, it looks interrupt is stuck, so I have to disable DRI, otherwise exa works fine. 2.6.25.19 and 2.6.26.7, I think. I have both of them on my system, and I think I tested with both of them. When I get home tonight (~8 hours from now) I will retest with both and see if I can get a 2.6.27 to test with too. Is there a bug filed on what you said about "it looks interrupt is stuck, so I have to disable DRI" that I can read? https://bugzilla.novell.com/show_bug.cgi?id=445320 seems to be this I am now running kernel 2.6.27.10, and it also shows the problem. I also tried using EXA with EXANoComposite, but it was still broken. I will attach some new logs. Created attachment 21343 [details]
Xorg.0.log with XAA and a 2.6.27.10 kernel - everything works

Xorg.0.log with EXA and a 2.6.27.10 kernel - nothing but garbage on monitor

.config for 2.6.27.10 kernel
The xorg.conf is unmodified except switching between no acceleration, XAA, and EXA.
Is there any more information I can give to help this get resolved? I didn't see this mentioned, but adding: Option "DRI" "false" to the Device section fixes the issue for me. I have AccelMethod as EXA and NoAccel left as default. Moving windows is not choppy like when NoAccel is "true". Just noticed Comment #6 mentions disabling DRI. I'll leave this in simply because it shows the xorg.conf option. EXA is going away, according to http://intellinuxgraphics.org/2009Q1.html, so this doesn't matter. UXA doesn't have this problem, anyway. Making a guess that this resolves as wontfix? |
