I experience exactly the same symptoms here (extremely slow typing speed, Dolphin very slow...), though it does not seem to be restricted to okular. It periodically happens when several of the following applications are running (this is my typical working environment): Azureus/Vuze, Dolphin, Dropbox, Firefox (especially with flash or java applets and/or multiple tabs), Kile, Kontact, Okular, Skype. It also happens with Nepomuk switched off.
My machine: Dell XPS M1330 laptop Intel(R) Core(TM)2 Duo CPU T7250 @ 2.00GHz 4 GB RAM GeForce 8400M GS with proprietary NVIDIA drivers OS: openSuSE 11.4 (sorry, I didn't want to file a new bug there, in order to avoid duplication) KDE 4.6 I suspect the problem to have something to do with the NVIDIA drivers, because I tried the nouveau drivers recently and the problem disappeared there. However, because of the GPU overheating with the nouveau drivers I had to switch back to the NVIDIA drivers. It would be interesting to know whether the original poster uses the NVIDIA drivers as well. I'm sorry not being able to provide more details as for now, I'd be happy to receive testing instructions. However, I cannot retry the nouveau drivers because of the heat problem mentioned above. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to okular in Ubuntu. https://bugs.launchpad.net/bugs/607041 Title: Periodically just about everything slows down to a crawl To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/okular/+bug/607041/+subscriptions -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
