I had the same problem when trying to load openSUSE 11.1 KDE LiveCD on my son’s desktop computer.
The CD would load up just fine on my computer, but on his it would stop at a GUI login screen showing the “Linux” user as an available option.
It didn’t matter which graphics mode we booted it with - XVGA, SVGA, VGA, VESA, etc. - it allways stopped at the same user login screen.
Then I tried booting up in plain text mode, and it worked!
Well, to be fair, you don’t get a Linux KDE desktop, but when prompted to login, it now accepts “root” as a user with no password required.
This is certainly not the purpose of a “LiveCD”, but it worked for me to start the “Live Installation”… simply start the “yast” configuration tool, go to “Miscelaneous”, then select “Live Installation”…
I was able to successfully install openSUSE 11.1 on my son’s desktop computer, and after rebooting, I had a fully working GUI KDE desktop at full resolution.
As to why the “LiveCD” load is not working, when you boot the CD in plain text mode you get a clear warning requiring at least 1GB of RAM to work, since the “LiveCD” version uses an in-memory disk to mount itself and install the “Live” desktop.
My computer has 4GB RAM, so it loaded up fine. My son’s computer has only 512MB RAM, so it failed to load the GUI desktop in “Live” mode. It worked fine after installing the OS onto his hard drive, though, as mentioned above.
I hope this helps other users having the same problem.
