[Bug 439138] Re: [karmic] Xorg 100% CPU utilization -- only after first login
Ok this is by no means scientific and is far from technical but here are
some findings.
Only got a new machine yesterday and installed the latest on it. I
noticed that my new laptop was sluggish and unresponsive to the point of
being unusable. Launched top to see 100% Xorg load. Found this bug on
the top of a google search and tried the logout / login, switch VT's but
nothing seemed to work, then the windows training kicked in if in
trouble/doubt reboot :) It was then that I noticed that the install CD
was in the drive. I removed it and choose to boot from the HDD. I have
HDD encryption on the drive and I noticed the password prompt text was
tiny, had not been that small last time I started the machine, the text
on the pre-splash screen was also tiny. Logged in and opened xterm (saw
that desktop effects were on, had not seen this before either). top
showed Xorg load was 1 or 2 % launched firefox, Xorg load rose to ~9%.
Put the install cd back in rebooted, choose to boot from HDD, the HDD
encryption password text was larger, opened xterm, Xorg load is 21->24%
launch firefox and meltdown !! unresponsive !! when xterm finally shows
up again 100% Xorg load. I then noticed that I can't remove the cd from
the drive at all. As soon as I click restart and the screen goes black
"* Will restart now" message is shown I can eject the cd.
I am using an Intel ThinkPad T500 standard model with Centrino 2 (all
specs on line) if further hardware info is required.
This is reproducible 100% of the time.
