[Bug 1594214] Re: ETPS/2 Elantech Touchpad inconsistently detected (Gigabyte P57W laptop)
@pjf, thank you for reporting this and helping make Ubuntu better.
Please execute the following command only once, as it will automatically gather debugging information, in a terminal:
apport-collect 1594214
** Description changed:
- On my Gigabyte P57W laptop (and possibly others, see:
- https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1526393 ) my ETPS/2
- Elantech touchpad is inconsistently detected at boot. Sometimes it's
- there, sometimes it's not, and I'm not sure of the circumstances which
- cause it to be detected or not. I'm on a 4.4 kernel, but trying a
- mainline 4.6 kernel did not help.
+ On my Gigabyte P57W laptop the ETPS/2 Elantech touchpad is
+ inconsistently detected at boot. Trying mainline 4.6 kernel did not
+ help.
- Luckily, after trawling the internet (
- http://askubuntu.com/questions/636350/elantech-touchpad-not-detected-
- anymore-on-ubuntu-15 ) I found that adding `i8042.kbdreset=1` to
- `GRUB_CMDLINE_LINUX_DEFAULT` in /etc/default/grub resolves the problem.
+ WORKAROUND: Add kernel boot parameter:
+ i8042.kbdreset=1
- The device is id=17 on xinput below. I *would* be running `lspci`, but
- my hardware is new enough that causes my machine to hang sometimes, but
- that's another bug...
