Ok, here at home, I'm running kde. After the last update, last week, and reboot (and that was a *real* mess - some issue I'm not sure I've resolved yet, trying to boot off RAID 1), here's what's started happening: I run in runlevel 3, and have a startx in my .bash_profile. At some point, just about every day, suddenly the toolbar on the bottom vanishes, as does my desktop wallpaper, the background goes black, and dmesg is showing me: plasma-desktop[22021]: segfault at 11 ip 00000034820ffd02 sp 00007fffa6a0b000 error 4 in libplasma.so.3.0.0[3482000000+218000] over and over. I <ctrl-alt-bksp>, it kills X, and I startx again, and I'm good... well, unless it does it to me again. Happened several times last evening. Any ideas, folks? mark
