Hello
I had a few problem with this upstream kernel.
Somehow I could not boot anymore and often got at the bootup to error message :
Gnome display manager. Dispatcher service... tpacpi::kbd_backlight
I reinstalled gdm3 and after a reboot, i could boot the computer. The
boot took however very long and still got stucked for a while (but i
did't looked at the command line)
But the touchpad now works and i can use the right click (Y)
Thanks
If I manage to reproduce the booting bug, I'll publish a new bug with more
informations
** Description changed:
Hello, I have seen different report of user regarding the right click
not working when pressing on the bottom of the touchscreen.
I however have a completely different problem.
- The touchpad is not working at all.
+ The touchpad is not working at all.
I cannot scroll. (no matter the configuration, the number of fingers or the
place of my fingers)
I cannot do a right-click (no matter the configuration in tweeks)
And the pointer randomly jump somewhere in the screen when I try pressing
with two fingers.
I previously had ubuntu 14.04 LTS which was perfectly working. After the
upgrade to 18.04 LTS this bug directly affected me. I really cannot use
my computer at all without right click.
Thanks for the fixing of this bug.
Sincerely,
Thomas
