I experienced the problem after I finally did a major update. Maybe it
is a udev vs evdev thing.
I do not have this probem on MX (you know, the old Mepis / Antix related
distro).
Funny thing is I cannot find xsettings or something there.
If only I would know where to look I could compare :)
There is a EXEGNU LiveCD with Trinity, if I recall correctly it is
working well there.
xinput (find you mouse)
xinput list-props ID
and then use xinput set-prop to set relevant ones
xinput --set-prop ID 'libinput Accel Profile Enabled' 0, 1
will set unaccelerated profile which you probably want on high dpi mouse
and if it still too fast, play with 'libinput Accel Speed'. f.e -0.5 will
set it to half, etc
P.S. It is possible that you mouse DPI is not detected properly by driver
use
ls -l /dev/input/by-id/
to find you mouse, then
udevadm info /dev/input/eventX | grep MOUSE_DPI
if its not set, use mouse-dpi-tool to find actual dpi and
create /etc/udev/hwdb.d/71-mouse.hwdb with values from it
I don't know if I can just post a huge "thank you!" here so I'll just
elaborate then.
mouse-dpi-tool is not working, it does nothing and then after CTRL-C it
gives a segmentation fault.
I created /etc/udev/hwdb.d/71-mouse-local.hwdb but that does not help.
This is what is in it:
mouse:usb:v062Ap0252:*
MOUSE_DPI=2000
mouse:usb:*:name:Emerge Uni-retractable Laser Mouse:
MOUSE_DPI=2000
mouse:usb:v062Ap0252:*
MOUSE_DPI=2000
I don't know where to set the default DPI in /etc/udev/hwdb.d/70-mouse.hwdb
Somehow I think udev is not used for this but evdev is, but I may be
very wrong.
Thank you so much, I'll investigate this further later.
