Betty, Start by telling us about this computer (Brand, Model, CPU, memory, and video card or chip). It might also help to know HOW you tried to install 12.04. For example, did you use a LiveCD and if so, did it boot and work Live? Or did you maybe select Install from the opening menu thereby bypassing running it in Live mode. If you did manage to get to a command prompt, try lshw -short to get some of that information. Based on that kind of information, we have a better chance of helping. For example, if it is a Toshiba laptop, it is likely that using apci=off, noacpi, or nomodeset on the boot line will help On Sat, May 12, 2012 at 9:39 AM, betty wrote: > I tried to install 12.04lts on one of my computers and I can get the sign > in at the beginning, but after i sign in the screen goes to black, if i > click the mouse it goesto a reddish color then back to black.
