xorg: Keyboard / mouse sometimes not detected/working

[^rooker]

[PROBLEM]
On a brand new Dell Vostro 1310, I'm experiencing a strange (and quite annoying) problem: Every now and then after a fresh reboot you can't login to the xserver, because keyboard and mouse don't work. After rebooting it usually works. hmpf.

[INVESTIGATION]
I haven't solved it yet, but it seems that others have the same problem: A Gentoo Wiki article about Dell Vostro notebooks mentions the following:

My solution was to add i8042.reset to the kernel parameters. The problem hasn't occurred since. This solution has also worked on a hp laptop with the same problem

This means that you just edit /boot/grub/menu.lst and search for a line like this:

Code: Select all

# kopt=root=UUID=... ro

and change it to:

Code: Select all

# kopt=root=UUID=... i8042.reset ro

Then run:

Code: Select all

sudo update-grub

I'm currently giving that a try. Let's see if it works!
