Xorg.conf

exa is commented out in this version because it is my working version, however
it was uncommented when I took the screenshots.
Comment 4 Erik Andren 2006-04-09 20:37:09 UTC
Does disabling fastwrite and/or lowering the AGP speed resolve your problem. 
Also, please post your xorg.log

My Xorg.0.log

Also I commented out the agpfastwrite and agpmode for this run.
Comment 6 Michel Dänzer 2006-04-10 18:01:33 UTC
Does Option "ColorTiling" "off" make a difference?

Please try xf86-video-ati CVS ati-1-0-branch, for both bugs you reported.

Ping to the bug submitter!
Comment 8 Caleb Cushing 2006-04-21 16:45:09 UTC
apologies my LUG is doing the computer room for Penguicon 4.0, and that's this
weekend. I've been a bit busy I'll try to get to it (cvs) by monday. I've got
"ColorTiling" "off" that may be helping but exa isn't on.

This log shows XAA being used.

> This log shows XAA being used.

in my overwhelming ignorance... that tells me what? I should remove it? how do
I do that? I don't see anything about it in my xorg.conf (which I'm attaching
again in case I've changed something).
Comment 12 Michel Dänzer 2006-04-26 20:41:26 UTC
You have to enable EXA explicitly with Option "AccelMethod" "EXA".

that I knew. I take it EXA is replacing XAA. If X had started without it I would
have. unfortunately X wouldn't start. I think it may have been evdev that failed
to initialize. which is another place where I'm trying to iron out a bug. I'll
try dropping evdev and see if I can get X to run with EXA.

well everything looks ok except for the fact that X is consuming 50%+ processor
usage and causing sysem lag. It's also above noramal on memory consumption
attaching an xorg.0.log to see if the cause of this lag can be determined.
Comment 15 Michel Dänzer 2006-04-27 00:08:04 UTC
You're saying the corruption with EXA is fixed? If so, please resolve this entry
as FIXED. For other issues, please add to other entries or file new ones.
Comment 16 Caleb Cushing 2006-04-27 05:37:13 UTC
with a little experimentation to confirm the source of result's it seems setting
colortiling to off fixed it. exa consumes an exoborant amount of cpu on my
system rendering it nearly unusable, and definintely in a state where I wouldn't
leave it on.
