I switched from suse to ubuntu when kde 4 became the default desktop on suse. I just did a SuSE 11.4 install from ubuntu 9.04. I have suse 11.3 running at home with no real problems. After installing 11.4 I noticed that KDE was a bit laggy. Slow to respond to mouse clicks and change of screen / desktop. Then it became slow to the point of total non-response to a mouse, keyboard or any other method of imput. After a couple of hard reboots I started up top to try and track things down. I have a quad core with 4 gig of ram and kernal 2.6.37.1-1.2 xorg 1.9.3 nvidia 260.19.44 firefox 4.0b12 vmware workstation 7.1.4 kde 4.6.0-6.6.2 All desktop effects are disabled. First of all... when I first start the machine xorg goes to over 25% and stays there. One core is pretty maxxed out. Nothing running at all in terms of programs I have started. Just a plain kde desktop. As near as I can tell it will keep one core close to max forever. Start firefox with about 4 tabs open and we are now over 80% and pegging up to 100% with two or three cores maxxed out. If I leave firefox alone it simply stays that high. Wave a mouse over firefox and it's now at 100% cpu on each core. Basically it seems as though any movement of a mouse over any program can peg a core to 100% in xorg. If I start vmware (which I need and use), merely starting it will result in two cores roaring to max. Actually running vmware and starting a virtual window (with xp in it) will result in all 4 cores being over 90% split between vmware and xorg and as long as I have a virtual machine running the cpu stays around 90% for every core. Even if nothing really is happening in the virtual machine. After all is said and done I am thinking the start of the problems is between xorg and kde. xorg being @ 25% cpu with only kde going leads me there. I just am not sure what I need to back off / install latest to resolve this problem. One thing for sure. The machine is unusable in its current condition. Having to hit the manual reset button because nothing happens on the monitor for 5 minutes is not good. Would I be better to simply go with 11.3 and kde 4.4 or so or Selectively uninstalling or use a different desktop. (ohhh for kde 3.5 :-) Realize that just to do my normal work, I need vmware, a browser, email, openoffice, postgres and apache going. Up until suse 11.4 this was easily possible. -- Dr. Roy F.
