After the installation of Ubuntu 14.04 on my acer Aspire E 11 laptop the touchpad was working normally. Two days later I accepted the upgrades shown in the Software Updater, then it won't be recognized anymore. The touchpad seems to left click, but won't move or right click. The update installed the following:
linux-generic-lts-wily linux-headers-generic-lts-wily linux-signed-image-generic-lts-wily linux-image-generic-lts-wily linux-signed-generic-lts-wily
I tried uninstalling these Packages and installing older linux-headers versions, but after selecting them in the grub menu even the wireless mouse won't work. What can i do to make my touchpad work again? Here is some additional information:
- xinput gives:
⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Logitech USB Receiver id=10 [slave pointer (2)] ⎜ ↳ Logitech USB Receiver id=11 [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)] ↳ Power Button id=8 [slave keyboard (3)] ↳ Sleep Button id=9 [slave keyboard (3)] ↳ HD WebCam id=12 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)] ↳ Acer WMI hotkeys id=14 [slave keyboard (3)]
- The package
is installed. I can't install the package xserver-xorg-input-synaptics, as the system complains:
Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:
The following packages have unmet dependencies: xserver-xorg-input-synaptics : Depends: xorg-input-abi-20 Depends: xserver-xorg-core (>= 2:220.127.116.112) E: Unable to correct problems, you have held broken packages.
- I also tried
sudo modprobe -r psmouse && sudo modprobe psmouse proto=imps with the old or new kernel loaded, and still nothing.
- dconf-editor is unable to find the touchpad.
- Forcing a install of xserver-xorg-input-synaptics with aptitude forces a lot of stuff to be uninstalled, so that the whole system won't boot and I all get is a black screen. (I formatted the system since then. At the first time i installed ubuntu 14.04, i clicked the automatic download of updates, so from beginning on the touchpad wasn't working)
I don't want to upgrade to Ubuntu 15.10, because the computer will constantly completely freeze and I have to hard reset it.
Thank you for the help!
