David - and all others, I now found a (minor?) clue to my problem (signal 11 on screen activity if xserver in background and virtual console in foreground): When I disable font anti-aliasing under KDE the xserver does NOT crash! Any idea now? (I still believe it's an xfree86 problem!) Thomas -- Thomas Winischhofer Vienna/Austria Check it out: mailto:tw@webit.com *** http://www.webit.com/tw ICQ# 63288080
