- Dell Inspiron 3551 Unresponsive Touchpad 4 answers
I've installed Ubuntu 15.10 on a new Dell Precision 5510 from a Live USB stick. I used the "Try without install" mode, and from there installed Ubuntu to the hard drive. During the install, the touchpad worked. However, in the newly installed system, the Synaptic touchpad isn't registering anything.
I've done a bit of digging, and I can confirm the following:
- The kernel sees the touchpad.
xinput listlists the touchpad.
evtestdoes see any events from the touch pad.
When I run
xinput list, I get the following:
Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ A4Tech USB Mouse id=11 [slave pointer (2)] ⎜ ↳ ELAN Touchscreen id=13 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=15 [slave pointer (2)] ⎜ ↳ DLL06E5:01 06CB:7A13 UNKNOWN id=17 [slave pointer (2)]
Now doing further digging, I've established that
id=17 are both trying to hog the touchpad, and as such, it's not working.
I can see that the touchpad is recognised in Settings > Mouse and Touchpad, and that options like disabling the touchpad, etc. are also present, and the touchpad is "enabled".
Is there any way to solve this? Can I just disable the
UNKNOWN touchpad? I'm not a linux expert, so might need pointers on basics. Any help is appreciated.
