I observed similar behavior using Ubuntu 6.10 AMD64 DVD ISO. During the DVD error check, there are several graphical problems:
1. The progress bars starts by doing a "Cylon Eye" scan (sweeps right, then back left) before it starts actually progressing to the right during the error check. I don't know if this is by-design due to some developer who was just trying to be "cute", or whether it's a code defect, but either way it's unintuitive to the user. 2. The progress bar contains graphical glitches (noisy/random pixels along the bottom-right edge). 3. The status text at the bottom of the screen appears in a very dark- grey color that is almost impossible to read; need brighter text. 4. (Not a graphical problem, and this may belong in a separate bug): The user can press CTL-ALT-F1 through CTL-ALT-F12 and switch virtual terminals while the error check is happening. Once that is done, I found no way to successfully switch back to the graphic screen (with the progress bar) that was initially presented. This is a horrible and unexpected user experience, especially for users with no prior Linux experience. I will come back and attach some digital camera shots of what I'm talking about. -- CD Error check progress bar goes forward then backwards https://launchpad.net/bugs/52026 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
