What I was /trying/ to say was that while I've not found it necessary to 
change accel profiles here, kde sees and keeps all the other mouse accel 
related settings I've set in xorg.conf.d just fine.

Since I hadn't had reason to try a different accel profile, I didn't know 
whether it would work or not, tho in the absence of other information, 
given that other settings worked, I would have guessed it would.

But you're now specifically saying it doesn't, and that if you DO try to 
set accel profile 2, kde "warps" the mouse to the top-left corner every 
five seconds or so.

I'd definitely call that a bug, and were it me, I'd check kde bugzilla 
and file it as such, if I couldn't find one already filed that I could CC 
myself too and perhaps vote for.


But now that you've described the warp to top-left every five seconds 
problem, I know of one further setting that might be involved, that you 
can check first.  It's a remote possibility, but maybe, just maybe, your 
mouse is interacting with things and somehow triggering this, so it's 
worth checking just to be sure.

kde settings, common appearance and behavior, shortcuts and gestures, 
global keyboard shortcuts.

Select kwin as the kde component.

Find the "Move Mouse to Focus" ("focus" being the 0,0 coordinate, 
generally the top left corner, so "moving to focus" seems to be exactly 
the behavior you're seeing!) action, and see if there's a keyboard accel 
set for it.

If there's something set, try either deleting that setting, or setting it 
to something else.

If there's nothing set, just in case, try setting it to something strange 
that you're unlikely to trigger by accident.

Then hit apply and see if that affects your ability to set accel profile 
2 without the "warping".  You might try logging out and back in too, just 
in case it doesn't activate immediately.


I don't see why that /should/ change the behavior you've described, but 
it's what immediately came to mind when you described warping to top-left 
and it's worth a shot.  If it /does/ work, somehow setting profile 2 is 
triggering repeated activation of whatever keyboard shortcut "move to 
focus" was configured with before, thus explaining the behavior you saw 
(and why it'd only occur in kde, since those keyboard shortcut settings 
are kwin specific), but leaving us with the mystery of what exactly is 
triggering that keyboard shortcut every five seconds when you set accel 
profile 2, and why!
