I recently installed Ubuntu server x64; I then realized there was no window manager built in (in retrospect it makes sense, didn't think of it at the time).
I have been having recurring crash report messages (system remains functional though) mainly before a shutdown or on login. As in general in Linux I don't think it is something normal, I am thinking If I am doing something wrong or how I could investigate further.
I am wondering whether going for the x64 and/or Ubuntu server + kubuntu package might have left some problems behind.
From my past experience with another UNIX o/s (FreeBSD) I never had crash issues.
