Few days ago, I've been confronted to a curious enigma with my mouse. I explain:
When I booted my debian, once gnome was launched, the cursor didn't want to move (neither 'click' by the way). After several reboot and dpkg-reconfigure xfree86-xserver, I decided to try under XP: it worked!. So it wasn't a physical trouble with my hardware. Then I booted a Kanotix live CD (sort of knoppix...): mouse cursor didn't move here too. Then I booted ubuntu: mouse was working.
And suddenly, I saw a little appendix connected to my PC by an usb port: an usb key! At this moment, in a quarter of second, all becomes limpid:
- In the fstab of my debian, I mount /dev/sda1 on boot (even if no hardware is connected)
- Kanotix mounts every storage device it detects
- XP, well...
- and in the fstab of ubuntu I don't ask to mount /dev/sda1.
So I unplug the usb key and reboot debian: mouse cursor moves!
Well okay... but why?
Do you have an idea?.
