I was using Ubuntu 11.04 32bit OS and in that I was facing a problem from today morning. My mouse freezes after 15 to 20 minutes of every login session. After that I upgraded the OS to Ubuntu 12.04.1 - 32bit OS and facing the same problem. Only my computer's mouse freezes and I'm able to navigate and work around without any problem using my PS2 keyboard attached. The only thing is mouse is not working after 15 to 20 minutes.
I tried almost all the solutions given in askubuntu and none of them helped me. I tried the following questions:
- Mouse Freezes On XOrg Load
- Mouse freezes after 20 minutes of use
- How to deal with a frozen screen?
- After login, mouse not working!
None of these questions helped me. I have tried changing my mouse and connected it to different USB ports. Nothing worked. I'm using a desktop PC with Intel motherboard, Core-i3 processor, Zebronics USB mouse and Zippys PS2 keyboard. How this issue can be resolved.
