1)I have installed ubuntu Server 9.0.4 edition on my Dell Studio 15 laptop with dual boot(with Windows Vista 64 bit) 2)It was working fine. Later i did apt-get ubuntu-desktop(not sure about the command-but it worked fine) 3)It was also working fine but it changed my boot screen, now i directly go to GNome Desktop rather than the shell prompt for login. 4)It was working fine but i wanted to set up my graphics card which is ATI Raedon 3400 -256 MB card. After that as and when i reboot-i get a garbled screen with out of sync colors. Please go thru the screen shot.The first screen is a snapshot when it reboots. 5) As i cannot enter anything-i tried "Ctrl+Alt+F7" to get terminal login. But i get the second screen. I tried recovering using server install CD but no success. Is the only way out is to reformat and re-install? Can somebody provide me kernel parameters and how to enter at GRUB boot loader so that i can go to the shell prompt and do the needfull Any help is highly appreciated. -- With best Regards: Ashutosh Sharma
