I have a Dell Latitude D410 that I bought used with Ubuntu installed on it. It worked fine for several months. I updated to 12.04. I wanted to read Nook books on it, so i tried to find the software to do so. I may have downloaded Wine onto the machine, but I don't remember. I discovered i could read my Nook books at the Barnes and Noble web site, so I did that a bit. The next day, when I started it, all I got was a black screen. Right clicking would produce a small box that allowed me to open a terminal window or a web browser, but nothing else. I decided to update to 14.04, which I think I did successfully, but now it's even worse. I can't even get the box to open a terminal window. Imma try installing 14.10 from a DVD, since I can get to the bios and change the boot order. I welcome any suggestions.
