Hi all,

I recently got my hands on a Gigabyte P34G laptop. (cant post links) its a powerful machine with top of the line hardware and nvidia graphics.

It has a lot of new hardware so my guess is that some parts might not be supported yet. After some good and LONG reading I figured out the UEFI+GPT stuff, so no need to bring it up in the thread below.

Mouse Issues - During the livecd (I booted into it several times before installig) I got the touchpad working intermittently. - After 3 restarts that it did not work I TABbed my way through the livecd. - After system was installed and I booted into it, no mouse. - next day, I got a usb mouse, it worked - at some pointed I noticed the touchpad was now working so I stopped using the usb-mouse - today, i booted and the touchpad was again not working. back to the usb mouse

Here the output of xinput

$ xinput 
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Logitech USB Optical Mouse                id=12   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Sleep Button                              id=8    [slave  keyboard (3)]
    ↳ Video Bus                                 id=9    [slave  keyboard (3)]
    ↳ Power Button                              id=10   [slave  keyboard (3)]
    ↳ HD WebCam                                 id=11   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=13   [slave  keyboard (3)]

If I open the mouse setting, the touchpad part is missing.

The outpur of the gdm log file related to mouse device:

# cat /var/log/gdm/\:0.log | grep mouse
(==) NOUVEAU(G0): Silken mouse enabled
(==) intel(0): Silken mouse enabled
(--) evdev: Logitech USB Optical Mouse: Found 3 mouse buttons
(II) evdev: Logitech USB Optical Mouse: Configuring as mouse
(II) config/udev: Adding input device Logitech USB Optical Mouse (/dev/input/mouse0)

So you can see the usb (logitech) mouse being detected, but not much info on the touchpad.

This happen on a Fedora 20 x64 installation.

UPDATE: got home. did nothing different. Turned on the laptop and... touchpad is working again.

$ xinput

⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Sleep Button                              id=8    [slave  keyboard (3)]
    ↳ Video Bus                                 id=9    [slave  keyboard (3)]
    ↳ Power Button                              id=10   [slave  keyboard (3)]
    ↳ HD WebCam                                 id=11   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=12   [slave  keyboard (3)]

I still have no clue what's going on.

You can find a kernel patch that should fix the issue here : https://bugzilla.kernel.org/show_bug.cgi?id=81331 However, it seems to be too hacky to be pushed in mainstream.

If you want a quick fix (but won't prevent the problem from happening again), it's easy, if you're on dual boot : boot once on Windows, then restart on Fedora.

Try to upgrade. If you already did try using the previous kernel.
