I am trying to install Ubuntu 11.10 inside Windows. When I boot up, I click esc and it takes me to the menu to choose which option I want. I choose 'Demo Mode', just to see if it would come up - it did not. I replaced 'quiet splash', with 'nomodeset', then booted it. A bunch of text comes up on screen, then it goes black. About 15 seconds later, I can hear the login sound playing, but it is a completely black screen. I can press my volume buttons on my keyboard, and I can hear it making a sound when I turn it up.

If it is a brightness problem (which I don't think it is), I have no way to increase brightness from my keyboard, nor monitor.

I'm not sure what's wrong, but it's bugging me!

Any help would be greatly appreciated. Thanks

Take a look at this:… Maybe something's wrong with the X Server-GPU feeding data which can be solved efficiently by following the steps on the X/Troubleshooting/Blank screen Wiki, at Please inform if you succeed. Good luck! – Geppettvs D'Constanzo Mar 4 '12 at 18:02
I've previously tried all of those workarounds, and none seem to work. I can't get into a terminal because I cannot install Ubuntu. However I can edit the command line before I start 'demo mode'. Any other recommendations? – Mister Insano Mar 4 '12 at 18:26
It would be helpful if you provide the brand name and model of your system, if it is related to a Desktop equipment you can try removing the GPU. Otherwise: try connecting an external monitor to your laptop in order to see if the GPU is handling the output via the external devices first, this means that you can change the behavior in the BIOS. Add as much information of your equipment as you can provide. – Geppettvs D'Constanzo Mar 4 '12 at 18:44

I also have no way to add or remove anything considering I don't have it installed, and cannot install it. I run it inside Windows. I have a Ubuntu folder in my C:\ Drive. Otherwise all I can do is edit the command line of 'normal mode' 'non graphical mode' 'demo mode', and theres a couple more. I can also bring up the command prompt by clicking 'c' – Mister Insano Mar 4 '12 at 19:00
