System: Compaq AlphaServer DS10 with redhat everything install. Problem: Permission on /var/tmp (drwxr-xr-x) on alpha redhat systems dont allow creating of temp/lock files by a non-root user. This causes XKEYBOARD keymap compiler (xkbcomp) to exit with write error and fall back to pre-keymap. Solution: Set permission to drwxrwxrt (sticky bit), as it is on i386 redhat.
This bug was caused by kdenetwork-1.1.2-2.alpha.rpm installation. It has nothing to do with X or filesystem rpm(s)
bug in kde packaging changed /var/tmp ownership, this was corrected.
