My apologies for the cross-post; I don't know which list is most appropriate for this topic.
I have a fair amount of UNIX experience but am new to GNU/Linux (I've been playing with the Knoppix live CD for a couple of weeks). Yesterday I installed Debian 3.1r2 ("Sarge") on my Windows PC. I installed the base OS just fine but am having trouble with X11 and KDE. For my original installation I chose the "desktop" task package installation (I don't remember the exact name) which installed GNOME and KDE. I then booted into GNOME with no problems (other than low screen resolution, 800x600). However, I wanted KDE, not GNOME , and spent several hours trying to disable GNOME before I gave up and reinstalled the base OS again with no additional packages. I then installed and configured kde-core, kdm, and x-windows-system-core (I want to start with a minimal environment and add to it). KDE didn't start automatically so (assuming that I missed something) I installed the entire kde package, which didn't solve the problem. I saw a note somewhere about starting X11 with "xstart"; I tried that and got an error (listed in /var/log/XFree86.0.log): Cannot open device /dev/input/mice It seems that X11 doesn't like my mouse (it's a PS/2 trackball). The mouse worked in Gnome yesterday (although it was auto-detected; not specifically selected) and works with Knoppix (using the same device: /dev/input/mice). I uninstalled all KDE packages and re-installed x-windows-system-core but the problem persists. My assumption is that I need to be able to see X11 processes running and/or be able to run "xstart" manually before proceeding with installing KDE again. Here are my questions: 1. How can I get X11 to work and verify that it's running correctly? 2. Once X11 is working, is there any reason why I can't install just kde-core and kdm to start with (as opposed to the full kde package)? Thanks. Steve Grace
