I've installed ubuntu 5.04, 5.10 and 6.06 beta on my pc many times already, and each time i install i will get error message "Failed to start the X server (your ghapical interface). It is likely that it is not set up correctly. Would you like to view the X server output to diagose the pronblem?" and when i answer YES, i got all the stuff that i don't know on the screen. my pc specification is: HDD 160G with 8partitions , AMD 3800+ x2 64bit, Radeon X700 PCI E 256MB, Gigabit A8N Sli Mother board.
