I just noticed that changing the theme from Oxygen to Air or vice versa also seems to stop de freezes. I have to add that I'm using a Core2Quad and that before switching theme the CPU usage was at 25% which means one core completely used and after change it fell at less than 10%. I suspect you have something that is near an infinite loop somewhere. Since the RAM usage is stable, there is no memory usage issue along with it... Try to use the command line application "top" to check which applications are consuming the CPU, also check the memory and swap levels. Thanks I just did that. Xorg is being reported as using between 92 to 98% of the CPU. When I switch the theme (going from Air to Oxygen or vice versa), the XOrg usage returns to normal, meaning an 7 to 8% of CPU usage. kwin and other KDE apps are noted as using something between 2 to 20% CPU usage during those and kwin seems to use more that it should when an action occurs after it started to freeze but it says acceptable. Meaning that the process that uses too much is Xorg but since it was not doing that with RC2 I still suppose it's KDE related. Hope it helps a little. - Do you use Desktop Compositing (effects) ? - Do you use some special plasmoid on your Desktop (a non-default or non-official one). - How many applications do you launch on start ? - Do you use Desktop Compositing (effects) ? > Yes, I use pretty much the default KUbuntu configuration - Do you use some special plasmoid on your Desktop (a non-default or non-official one). > No, nothing that is not provided by default, on top of that I didn't activated much more that what was already. - How many applications do you launch on start ? > Let's see... 3 I think. That makes Firefox 3, Amarok 2 and Konsole. It can freeze with only those 3 started along with Instantbird. I obviously have with that the normal KDE applets and some services that runs but I didn't change anything about that between RC2 which was working fine and RC3 which is not... Whoops, sorry. Choosing the '>' character to mark my answers was definitely a bad idea... What happen if you disable compositing at the start ? Do you get to the same freeze/cpu-consuming situation ? Thanks I'll have to test that later. I'll let you know the results as soon as I have them. OK, I just tried to disable compositing, logout and login anew and then went to bed. When I returned this morning Xorg was another time taking a whole CPU and the UI was completely unresponsive. It was at least as bad as with compositing enabled. Ok. Bug fixed on the 4.3 official release as far as I can say. That's better. I would have hated to downgrade to 4.2. |
