I created a presentation and started editing it, and almost immediately everything started hanging. No mouse, no Ctrl-Alt-Fx for virtual consoles, system doesn't respond. After waiting for a few minutes, the system briefly jumped to the F1 virtual console I requested, but then I got a Unity login screen, so maybe X had crashed and restarted.
Ever since then the touchpad doesn't work. I tried rebooting, "synclient TouchpadOff=0" (it's set to 2 otherwise) and touchpad-inicator - which also has an effect on the TouchpadOff variable - but nothing helps. I tried to follow some X package installation advice, but the package cannot be installed due to errors. xinput lists the Touchpad:
⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ETPS/2 Elantech Touchpad id=14 [slave pointer (2)] ⎜ ↳ Logitech USB Optical Mouse id=10 [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)] ↳ Video Bus id=8 [slave keyboard (3)] ↳ Sleep Button id=9 [slave keyboard (3)] ↳ Lenovo EasyCamera id=11 [slave keyboard (3)] ↳ Ideapad extra buttons id=12 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
Anyone who went through this before? Should I completely reinstall the system?
