KDE4 - Plasma lock up

view full story

http://forums.opensuse.org – I've been experiencing a strange problem with Plasma locking up. Running system monitor it shows the KDE4 process using 20% CPU time, and Plasma around 10-15%. This seems way too much since on my six year old Laptop the cpu load of both processes is barely noticeable. My Laptop is an old single core 3000+ AMD Athlon 64, while my Desktop has a Quad core Xeon 2.33Ghz chip, so the fact that the KDE4/Plasma system load is many times higher than on the Laptop, indicates something is wrong. I'm not sure what else to look for troubleshooting wise, any suggestions? *Actually, thinking about it, the KDE4 process is timing out one CPU core, which indicates to me something is really not right.
