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.
