So here's one I've not encountered before; I installed Linux Mint 16 w/Cinnamon on my mother's laptop (a Dell Latitude D620, 3G RAM, 120g SSD). While it's awesome I was able to convince her to not use XP any more and switch to Linux, she's got this one weird issue where the cursor will get stuck on the wrong cursor.
Normally the cursor is the arrow, but as you all know, there are many alternate ones you see if you move something, resize a window, and so on. The thing is, it always falls back to the default cursor when done those things. On her laptop, the cursor seems to get stuck after a while, most often on the text-entry cursor (the one looks like an "I"). This makes it harder to use since it's not an arrow any more.
Now, if you log out, and log back in, the cursor is okay again... for a while. It always seems to get stuck after a time though. Does anyone have any idea of what could be causing that? Even if not, is there any way to write some sorta timed cron job to reset the cursors every couple of minutes or so?
