Hello!
I use IceWM and in startup script there is
xset m 0 0
for mouse.
When the system is loaded, mouse speed is just what I need. And I have APC Line-R 1200.
I can't recall when the problem started but when my APC Line-R switches modes and clicks (it clicks every time when switches), ~20% of the times mouse speed sets way higher than "xset m 0 0". So it becomes uncomfortable to work. I have to do
xset m 0 0
in urxvt everytime to get it back. It didn't happen when I was using Gnome2 though (several months ago).
Sometimes when APC clicks and I move a cursor this moment - it might freeze for ~0.5 sec. And then speed changes.
Does anybody know - what kind of problem this is?

No idea but I'm sure xset 'forgot' its settings for me in the past and I don't have a voltage regulator.
If you're using evdev edit the "evdev pointer catchall" in /etc/X11/xorg.conf.d/10-evdev.conf adding the two options at the bottom:
Section "InputClass"
Identifier "evdev pointer catchall"
MatchIsPointer "on"
MatchDevicePath "/dev/input/event*"
Driver "evdev"
Option "AccelerationProfile" "-1"
Option "AccelerationScheme" "none"
EndSection
These options basically do the same thing as xset m 0 0. Maybe it'll help.

Thanks man. I chaged these options and will see during the day how this is going...

It sounds like your power regulator is not switching smoothly. A voltage drop might be occurring when the power supply switches taps and this glitch is being propagated through the PC's hardware.
Have you checked dmesg for USB and mouse dropouts and reconnections? I'm assuming you have a USB mouse.

[ 3791.989645] usb 2-1: new full speed USB device number 3 using uhci_hcd
Looks like my mouse really gets disconnected because of the APC.

That's right. High-speed USB mouse.
smudge, your advice works. Speed now keeps its value after those reconnections. But I'm very disappointed in my Line-R 1200...

I remembered after posting the above that xset was losing it's settings because my old mouse developed a loose connection so was disconnecting and reconnecting just as yours is. So it might be the mouse not the Line-R.
Just waggle & twist your mouse about and see if you get lots of messages in dmesg

I tried to but as I expected - this doesn't make disconnections because disconnections registered in dmesg happen only when Line-R switches. I observe speed changed only right after APC clicks.
