Radeon 6450 installation problem
I'm trying to install an HIS Radeon 6450 graphics card into my 32 bit Ubuntu 12.04 Dell Inspiron 530 system and am having problems. Upon power-up, the system starts to boot, some text goes across the screen, a light purple background shows for a few seconds followed by garbled video. After a minute or so, the screen goes black and the monitor goes to sleep. I tried booting from an Ubuntu 12.04 live CD and the results were the same. Ctrl-alt-F1 doesn't get me to a console so I'm not sure what to do from here. I was able to get to a grub console through the boot menu but I'm not sure what to do from there either. Was wondering if video parameters need to be changed to be compatible with my monitor but not sure how to accomplish this from the grub console. To verify the live cd as good I tried booting an old windows machine with it and that worked fine.
Any help would be much appreciated.
