View Full Version : [ubuntu] Screen flashing every 1/2 second after selecting "Extra" graphics

Help! I am new to Ubuntu and Linux (2-ish weeks) and looked up my issue on the net but don't understand the solutions or even know if it is the same problem as mine. For the first 2 weeks that I had Ubuntu, it was set to default "simple" graphics, under System, but yesterday I was bored and set it to "Extra", which is the most fancy it can get. It was ok at first but when I shut it down and restarted, the screen was flashing every 1/2 second. Due to the flashing, I couldn't do anything but login and shut it off. I couldn't even access the "System" tab to undo what I think caused the problem.

I tried running it on Recovery and set it to "Failsafe graphics", which worked but I don't know how to undo what I did, without running it on recovery. Help! I miss my computer dearly!!

Also, I am not computer savvy so PLEASE explain the solution in teeny-tiny baby steps. In English and great detail.

Thank you!! :)
