I seem unable to configure mouse pointer acceleration.
The mouse pointer
moves way too fast, beyond usability. Acceleration is set to 1.0 in TCC.
Sometimes I can change that setting, reset to 1.0, and the mouse pointer
behaves but often not.
Pretty much renders the desktop unusable.
Ideas?
Problem resolved.
I remembered a similar mouse issue reported two months ago:
https://mail.trinitydesktop.org/mailman3/hyperkitty/list/users@trinitydeskt…
With that issue the root cause was libinput. Using evdev resolved that
problem.
The current system with the fast mouse speed was updated recently from
Slackware 14.2 to 15.0. Those previous evdev adjustments were not
migrated to this system. I had forgotten about them until this afternoon
when I was looking into a different paper cut on a different DE. The
mouse configuration did not support several common options. That is when
I remembered the previous issue and solution.
At that point I wondered if this new issue had the same root cause. Yes
indeed.
I never reported back on that first problem but the solution was
renaming two files:
cd /usr/share/X11/xorg.conf.d
mv 40-libinput.conf 40-libinput.conf.bak
mv 91-keyboard-layout-libinput.conf 91-keyboard-layout-libinput.conf.bak
There are related solutions such as creating xorg.conf.d files that
provide the same outcome.
Although this solution helps resolves both problems there remains the
fact that these mouse problems appear only in TDE.
