I never had this problem before, everything booted up fine but when i install the AMD radeon HD 6xxxm linux_x86_64 drivers i get the black screen after startx. (i unzipped it, then sh./filename, then installed it then restart laptop). Anybody know why? Ive done the changing grub to add i915.modeset=1 (before i installed the drivers) so it isn't that. Its never happened before. BT r3 im using

I have samsung chonos 7 AMD radeon HD 6750m

Thankyou for the help.
