Red Hat Bugzilla – Bug 138616
Display config takes a long time to start up.

Description of problem: Go to Applications\System Settings\Display Wait :) How reproducible: 100% here. I'm using a fresh install of FC3 with the following hardware: IIyama LS902UTBK, Asus Radeon 9200SE.
Does kudzu -p -b ddc run as root also seem slow? It could be we're waiting for the probe data.
Right now both of them (kudzu and display config) take about 5 seconds, is this considered slow or normal ? The output from kudzu seems correct expect for this: mem: 16384 Does this mean kudzu thinks my graphics card only has 16MiB of RAM (it has 128) ?
OK looks as if ddc probing is slow on your h/w. Can you paste the output of the kudzu probe into the report.

Can you attach the output of 'strace -tt /usr/sbin/kudzu -p -b ddc'?
That file is 33MBs big, are you sure you want me to upload it ? For now, I'll upload a short version of it, since the majority of the original file contains the same message over and over again.

What does 'cat <whatever> | grep vm86 | wc -l' say?
[steven@max ~]$ cat strace.txt | grep vm86 | wc -l 233412
Realistically, this code is not going to change appreciably in the near future in a way that would speed this up. Hence, closing this report.
