Hi,
Since a few days, to get my touchpad working “properly” (speed and natural scrolling) I have to log out/log in after every single reboot.
Right after a reboot, the touchpad is slow & without natural scrolling, but after logging out / logging in it’s as fast as I wanted with natural scrolling
Here’s the output of xinput
<lucas> ~ % ~> xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech Wireless Mouse id=10 [slave pointer (2)]
⎜ ↳ SYNA2393:00 06CB:7A13 Mouse id=12 [slave pointer (2)]
⎜ ↳ SYNA2393:00 06CB:7A13 Touchpad id=13 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=18 [slave pointer (2)]
After looking at input properties and more specifically the Natural scrolling property :
<lucas> ~ % ~> xinput list-props 13
Device 'SYNA2393:00 06CB:7A13 Touchpad':
Device Enabled (196): 1
Coordinate Transformation Matrix (198): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
...
libinput Natural Scrolling Enabled (333): 1
libinput Natural Scrolling Enabled Default (334): 0
...
and
<lucas> ~ % ~> xinput list-props 18
Device 'SynPS/2 Synaptics TouchPad':
Device Enabled (196): 1
Coordinate Transformation Matrix (198): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
...
libinput Natural Scrolling Enabled (333): 0
libinput Natural Scrolling Enabled Default (334): 0
...
I saw that SynPS/2 doesn’t have natural scrolling enabled and if I try to enable by default it I get this output (I get the same when I do it with the other one [id=13]):
<lucas> ~ % ~> sudo xinput set-prop 18 334 1
X Error of failed request: BadAccess (attempt to access private resource denied)
Major opcode of failed request: 131 (XInputExtension)
Minor opcode of failed request: 57 ()
Serial number of failed request: 20
Current serial number in output stream: 21
Though xinput set-prop 18 333 1 enable Natural scrolling for SynPS/2, the pointer is still slow until I log out / log in. I can changed any setting (in Settings > Input devices > Touchpad) and then apply, it won’t do anything (which is why I think of a second “profile”)
After a log out / log in after rebooting, I get other settings (the ones I set) and then any modification (acceleration, natural scrolling) takes affect right after applying
The only thing I do to get my settings back is logging out then logging (not rebooting)
This are my Xorg confs
<lucas> /etc/X11 % ~> ls
tigervnc xinit xorg.conf.d
<lucas> /etc/X11 % ~> ls xorg.conf.d
00-keyboard.conf 30-touchpad.conf

If anyone has an idea of how I can “delete” this “second” profile of touchpad, I’ll be very thankful. In the
meantime, i’ll stick to logging out and logging in
