KDE suddenly stopped working F17

[juanfgs]

All of a sudden kde started crashing at init, I just started systemsettings once (which crashed selecting appearance) and then some qt apps and every kde app refused to start (amarok, clementine, etc) segfaulting at the start.

Ksplash stops at the third icon, I can see that for a second appears the crash manager and then dissapears.

has anyone experienced this?

I already tried moviing the entire configuration folder, deleting cache files, rebooting, but it's strange I didn't do anything in the OS that could cause this.

Besides deleting ~/.kde (and maybe stuff in ~/.cache and ~/.local) you have to delete the settings it keeps in /var.

Also deleting ~/.kde is really bad, that will wipe out all your mail (kmail puts the email under ~/.kde/share/apps/kmail/mail ) among other things. Better is to move ~/.kde to ~/.kde.save and the recover things like email as needed

Solved, the culprit seems to be the Nvidia propietary driver (version .53), as yesterday (magically) it stopped recognizing the EDID data from my monitor, supporting only 1024x768, after updating to the latest (.59) which STILL didn't recognize the EDID data and fiddling with modelines and xorg.conf (which reminded me my old days with debian sarge and slackware).

Why are these things failing randomly is beyond me...

I'm also gettting random crashes during KDE startup,
My Nvidia version is 302.17 ,
do you know what Xorg settings fixed your problem?
