Adding i8042.nopnp to the kernel command-line in grub fixed it for my mouse, on an HP Compaq DX2000 MT.
My PS/2 mouse (but not the PS/2 keyboard) had been broken since I rebooted for the first time after the upgrade to Hardy desktop, from Dapper. For newbies reading this and wanting to try it: 1-time fix: get a boot menu (you may have to press ESC at boot-time if yours doesn't let you choose what to boot). Press 'E' at the boot menu to edit the commands for the linux you want to boot (probably the default, or more recent version). Move the cursor to the kernel line that starts "/boot/vmlinuz-2.6..... root=......." or similar, and press E to edit it and go to the end of the line and add "i8042.nopnp" without the quotes, then press enter to accept and B to boot it). If this makes it work, a permanent solution is to edit /boot/grub/menu.lst as root (eg. Alt-F2 and type "sudo gedit /boot/grub/menu.lst", for instance), and add the same i8042.nopnp text after the "# kopt=root=..." line that looks a bit like the line I mention above; then run: sudo dpkg-reconfigure grub. -- PS/2 doesn't work after upgrading to feisty [i8042] https://bugs.launchpad.net/bugs/95785 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
