I've been having this issue with my cursor lately where my cursor is squished and has those colorful bars under it, and I can't seem to figure out what to do. I'm also not sure what would have caused my computer to suddenly start doing this.
Here is a picture I had to take with my phone, more on that later. //phone picture
I'm currently running Ubuntu 14.04 with the MATE desktop environment. My cursor did not do this when I installed MATE onto my computer, and even reverting back to earlier kernels and updates doesn't seem to fix it. I've had Ubuntu installed on my computer for almost a year now, and I've used Linux (primarily CentOS minimum and Ubuntu) for some time now.
My current computer is an older (approx 2-3 years) Lenovo G50-45 with 16gb ram, and AMD R5/A8 hardware.
I haven't changed any drivers, they are the same as when I installed Ubuntu.
What's most curious is that a screenshot (the one I posted of my desktop) shows the cursor to be normal when it's not.
-updating/upgrading and restarting
-autoremove (worth a try)
-sudo apt-get install --fix-broken
-trying older kernels from GRUB
-Ctrl+Alt+F1 then Ctrl+Alt+F7
-reverting back to an earlier state
-removing the desktop environment I use and re-installing
-removing all other desktop environments, and leaving just MATE
-resizing my desktop, changing my cursor and theme
I'm thinking at this point the only thing left to do is back up my stuff and re-install linux. I'm currently in college and busy so I'd rather not spend valuable hours starting over unless I had no other choice.
Are there any other things I may be overlooking?
