Obviously you have never been in a terminal session before or you would have known what to do.
...And this is why Linux will never be a success on the desktop.
Linux doesn't work on your video card? You just need to allow it to boot to a terminal session (you do know how to use a command line, don't you?), fire up your copy of vi (you do know how to use vi, don't you?) and modify these configuration files (you do know where the configuration files are, don't you?) Don't know what to modify it to? Post on this random forum and, if you're in luck, user eLi86Hxor will explain it within 72 hours in terms that way over-estimates your level of Linux drivers knowledge. Be sure to copy the answer exactly, because this configuration file is very fussy about white space characters (you do know what white space characters are, don't you?) Then you need to re-compile the driver, of course. But you definitely know how to do that, don't you?
Easy, huh? Can't see why an average end-user would have a problem with any of this.
And if it still doesn't work, go back to the forum where a number of users will be happy to explain to you that the problem is with you, not Linux.
