I am having similar problems here
It seems to be linked to the Nvidia drivers and certain GL screen savers if i use the Fireworks 3D (GL) screen saver i get the lockups of the mouse cursor if i Ctrl+Tab to the next desktop all is ok again mouse everyting if it then go back to the desktop with Control Center open on it with the Fireworks 3D screensaver highlited it locks again until i can nudge the mouse a bit at a time to select another saver .
Runnig Nvidia FX5200 128Mb suse 9.2 KDE 3.3.2 the latest Nvidia drivers have also tried the previous driver still the same .
I believe it may be kernel related to the 2.6.8-24.10-default kernel i have not backdated to a previous kernel yet not had time anyone tried yet interested to see if it sorts it out .
Pete .
Well it's three of us so far. But, I'm afraid there's not much common to the three cases together. I have two *identcal* HP Compaq d530 computers here - one running suse9.1 (dual boot with winXP) and one running suse9.2 (fully updated to KDE 3.3.2 and kernel 2.6.8-24.10-default)...Only suse9.2 machine has the mentioned problems, even after I swapped mouses between the two (Laugh now, Bred!). So, Peter, No nVidia here, as you see. It's Intel 865G (i810). Also, the symptoms that I mentioned occur regardless of screen saver in use, being active or inactive. Further, my mouse cursor is not locked - it just disappears, while system stops responding to mouse events. System keeps responding to keyboard, my screen is refreshing as normal, no signs of anything taking too much CPU cycles or such. I also can connect to comp via ssh and all is fine. It's just my mouse that dies, making my desktop operation *very* uncomfortable. The only way that I found out of this is to kill the whole X thing (ctrl-alt-bkspace) and to log in again to KDE session. I don't need to shutdown/restart the OS like Gary. It's enough just to restart X. Another strange thing is that I can not log out of my session normally - if I go to "end session" screen (ctrl-alt-del) I can not do anything anymore, except ctrl-alt-backspace....(Another difference to Gary's case). I hope "there must be some kind of way out of here" (Dylan/Hendrix)... What are the processes that control/'respond to' the mouse? My perception of linux so far is that almost all problems can be solved "in vivo" with minimum disruption of the rest of the system. Just stopping and restarting certain process(es) helped me so many times...Hope this time too. Thanks for your answers, guys. It would be nice if more people contribute to this thread, TIA. cikasole
