The original USB drive I used to install 12.04 was created on Lucid, and did not work well on my system. However, it did work on another laptop I have. (the initial load screen did not work and I still only saw the grey rectangle in the lower left corner, but the Ubuntu screen and afterwards worked fine.)
After installing on the second laptop I created a new USB drive from that system. (This was creating a boot USB drive using 12.04.) Then using that new USB drive I had a different experience. Upon booting the Dell 1720 with the new USB drive the initial boot screen came up and I continued to boot up as a LiveCD. The Ubuntu screen came up fine, and then the prompt came up asking if I wanted to Install or Try. I chose Try, and then the screen went into black and white stripes with a garbled mess. So the Try option did not work. Second try I selected "Install from the boot screen and the install process went fine. I now have a fully functional running 12.04 OS on the Dell 1720, even though the LiveCD option would only display garbled graphics. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/989372 Title: 12.04 usb drive boot graphic problems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/989372/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
