http://ubuntuforums.org – Greetings, I am having trouble seeing any desktop after clean install. I'm not an expert (more of a noob than anything), but I've tried doing my reading and work on this as best I could. I'm hoping someone out there can help. Thanks in advance. Big Picture: Monitor will show "splash screen" of whatever distro I choose (Xbuntu, Lubuntu or Ubuntu), but after the nice little spalsh it trys to display the login screen, but the monitor craps out. Whay am I using a monitor instead of the laptop screen? I have to use the monitor as the screem on the laptop is busted. Specs: (Hardware)
