For other reasons, I completely re-installed 9.04 UNR, formatting the SSD to ext4. The problem is not occuring now.
Possibly a dupe of 239943 but I didn't monitor CPU usage when I had the problem so can not confirm. Sorry for the poor information. Fixed for me now. -- Slow Desktop Menu on UNR 9.04 https://bugs.launchpad.net/bugs/366562 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
