My mouse pointer started misbehaving after a big update, which followed the newest regular kernel update, a few days back - nothing buggy happened after the new kernel; but only after the subsequent update.
After a fresh boot, now the pointer is either invisible (but still able to fully operate, otherwise), or it is just a big X. However, as soon as I open an app, it will activate the pointer - and the rest of the session is normal.
I have done the easy stuff: tweaked Compiz, Appearances, and reset my default pointer in the system files, but no help; everything else is perfect, though but this single annoyance.
I was hoping someone knew of a fix; thanks!
