I installed LM 12 over a month ago, and it has been working fine. Came down this morning and found that the screen goes black after the bios screen and then an "input not supported" message bounces around the screen. Nothing else happens.
I tried to use shift to get into the grub menu, but it does not work. I tried a different monitor: the error message went to "frequency out of range", but nothing else was different.
I'm using LM 12 32 bit ; 2 gig of RAM with a Phenom2 Quad core processor and onboard Nividia graphics. I've been using Linux for a while but I'm not that great with system modification. I have a very limited amount of terminal experience, so be nice!
I work at home on this computer, so it's really important. Thanks for considering!
