I'm new to xubuntu (only because my laptop won't run any modern linux flavour).[pentium m] Randomly I would get a keyboard hang up - no warning. (when i say this, a couple of times the menu also did not work) The mouse still works and if I switch to another tty, the keyboard works fine. from here I can run an init 6 to reboot the system and all is well again.

I have noticed that it is more prone to happen when I use the keyboad shotcuts on my laptop, for instance fn+vol up or fn+vol down.

I have not installed proprietary ati drivers nor changed keymappings. updated or unupdated, it does the dame thing. (I have now installed 12 times)

attached is my hardinfo:

I had some issues on a similar Centrino M laptop a while ago:

  • total blackout when using the fn keys to dim the LCD panel
  • total lockup when using the fn keys to query the battery level.

It seemed to me that these functions were hardwired into the BIOS and only tested with Windows. The workaround at the time was to append the kernel command line with NOAPIC NOLAPIC, ymmv.
