I have been using Ubuntu 12.04 for a couple of months now with no problems. Then one day I restarted my computer, and it would not detect the monitor. If I force it to restart a few times, it finally gets me to a grub screen where I can only boot in recovery mode, and then it only displays in a v. low resolution. I don't have multiple monitors. I'm using a ViewSonic VP2330wb, and have an Intel graphics driver, which I have updated and it still doesn't fix the problem. I have been using the same monitor since I got the computer, and this has never been a problem.
I would really love to fix this without having to reinstall.
Thanks.
