Display and load issues in KDE 4.7.3 [Solved]

[troyvit]

Hi forum,

I just updated (via aptitude full-upgrade) to KDE 4.4 and since I have KDE has become unusable:

- I can open an application but:
- eventually giant blank squares start showing up in the middle of the program's window.
- whole panes in a program (like claws-mail) become blank. Resizing the window sometimes brings it back.
- menus become unresponsive.
- X load goes through the roof.
- examples of 2 programs that behave this way are claws-mail and firefox, but I also see similar behavior when I click the k menu or the launcher (alt-f2).

These problems only present themselves in KDE. Gnome is unaffected.

- Things I've done to try to fix it:
- turn off compositing.
- remove my .kde folder and restart X.
- turn of Sync to VBlank wherever I could find it in nvidia-settings.
- re-build my xorg file using nvidia-xconfig and restart X.
- choose a different KDE theme (Switched to Air from Oxygen).
- Log in using KDE Failsafe (that helps a little bit).

- Stats about my setup
- System76 Gazelle with an external Samsung monitor
- NVIDIA GeForce GTX 560M (that's what my xorg.conf file says anyway)
- uname -a: Linux munin 3.0.0-14-generic #23-Ubuntu SMP Mon Nov 21 20:28:43 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

Has anybody else had similar problems? Any ideas of workarounds?

Thanks!

Troy

Why are you staying at such an old version, Kubuntu is now at KDE4.7.4.

My bad that was a typo. I'm really running 4.7.3. My repos in Oneiric don't show 4.7.4 as being available.

To get 4.7.4, drop to a console (ctrl+alt+f1) and do:

sudo service kdm stop

(this shuts down kdm and X system)

sudo apt-add-repository ppa:kubuntu-ppa/ppa
sudo apt-get update
sudo apt-get dist-upgrade

sudo service kdm start

(to restart kdm and X)

I usually update my DE like this, I believe it's safer.

Thanks. I was missing that PPA. Once I installed it and upgraded all seems well again. I must've accidentally yanked that repo at some point.
