Bug Description
After upgrading to ubuntu 9.04 from 8.1, I noticed excessive cpu usage and sluggishness on my computer. I think there might be something going on when the remote desktop is enabled because when I disabled that feature, cpu usage went down considerably. Although remote desktop was enabled, I wasn't using it during the excessive cpu usage and it didn't show up in the different ways I was trying to find out what was hogging all my cpu. Even with it off, cpu usage is about 20% on each my 2 cores (was at 60-80% on both cores with remote desktop enabled), without much running other then firefox and totem at the moment (this is noticeably more then ubuntu 8.1). Let me know if there's any other information I can provide to help...
Thanks

I'm a Ubuntu user for the last 4 months and I'm just in love with linux (upgraded from windows vista), and don't understand why windows is still in business with linux and mac os around. I'm a new user and trying to learn everything as fast I can, but I have to say that you guys are awesome!!!

I am also seeing the same problem.
The machine is a laptop Thinkpad T61p.
When remote desktop is enable the cpu goes to 25-35% turn off the remote desktop drop the cpu normal level (1%-3%).
This did not cause a problem on 8.10.
The problem exists with both nvida 180 driver and free driver. It looks to be something in the remote desk top server. It
was spawning over and over. I could see the PID for the server task keep increasing but did not see anything in
syslog or messages.
This was a clean install of 9.04.
For now have turned off the remote desktop.
