I'm running 10.10 on a 5 year old laptop, and it's worked fine. A few days ago this problem started happening where I can't click on anything. I'll have to alt f4 out of the program then open the program up again. Then when I reopen the program I can't really click on things directly. For example I'll have to right click and leave that menu open, then go and left click my browser tab to close. Then eventually nothing is clickable and alt f4 doesn't work and I'll have to hard reset my computer.
I'm not familiar with the troubleshooting steps in Ubuntu. I didn't make use of partitions for my files, so I'd rather avoid having to reinstall everything. What kind of diagnostic programs can I use to find out the most likely problem?
I'm guessing that it's some kind of UI problem. Visual effects are turned off.
