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. -- High cpu usage caused by Remote Desktop? https://bugs.launchpad.net/bugs/367087 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
