I started to have a very strange problem after several months since I installed ubuntu 7.10 x64 from received official CD.
When I click "green running man" and then 'lock screen' it either does not locks at all or locks after several minutes. Sometimes everything turn out to be unclickable including keyboard, system seems to be hanging, but when I come back in the morning, I see locking window, so night is enough to lock my workstation
I do not see any other performance issues, my PC is quite new and both CPUs are not 100% busy.
I have not found that topic on the forum, probably my problem is new.
Have anyone had similar problem?
Thanks in advance
