    Ubuntu linux freezing on dell optiplex 740 small form factor desktop

    I'm not sure if this post is in the right area or not. I have a dell 740 optiplex small form factor desktop that I'd like to use with ubuntu linux. I have a 64 bit desktop so I'd like to use ubuntu linux version 14.04 64 bit from the download section. I'd like to run linux only off of a DVD and just learn it.

    The problem is that when I do this, ubuntu always freezes on me. When I boot off of the DVD, I click on try ubuntu, the ubuntu desktop appears and then my system just freezes right there. I can't move the mouse and the keyboard doesn't work. I can't eject the optical disk drive. The only option is to hold in the power button to turn the system off.

    How much RAM does your computer have? The LiveDvD's run directly in your computers Random Access Memory [RAM] and so if it doesn't have enough RAM I could see it failing to run or freezing etc...

    I looked at ram information in detail. I have 2 gigs of ram, but I can increase that to 8 gigs of ram. If I don't have enough ram to begin with, that would make sense. Are there any system requirements for running the live DVD?

    2 gig of ram is fine. Don't know about your video though.

    Have you tried nomodeset?

    I haven't tried nomodeset yet. I'll see what happens with that. My video is on board. I don't have an actual graphics card so whatever the dell desktop uses for video is what I have.

    I turned nomodeset on and that fixed the problem. Thank you so much.
