Command line - now that's a good start!
Have you gotten used to any text editor? You may be aware of the eternal war between vi and emacs adepts. I never got used to either of them. I need something easy and simple like nano. But Mandrake doesn't supply that. Maybe they have pico, but I seem to remember it has neither.
Anyway, for the mouse thing check /etc/X11/XF86Config - it's rather long, but it should have a section on the mouse. See what it says there. I also suggest you do a Google search on your mouse, it could be something completely different.
/etc/localtime should be a link to /usr/share/zoneinfo/Europe/Amsterdam (in my case, you may live somewhere else) which you can check with
ls -l /etc/localtime
I also have a line in /etc/rc.conf that says CLOCK="local" but Mandrake may do things differently (check the Mandrake Control Center in GUI). It seems in Mandrake you need to have /etc/sysconfig/clock to say
UTC=false. This you can check with
cat /etc/sysconfig/clock. Have a look at
