My screen resolution is 1600x900p normally. Without specific graphic drivers it 900p in GRUB and ttys, too. If i install fglrx as driver it is set to 640x480p when i start a tty, and the widescreen causes big "pulled" letters on my screen. Does Anyone know how to fix that?

This is because fglrx (the proprietary AMD Radeon device driver) does not support Kernel-Mode Setting (KMS).

In the GRUB (boot loader) configuration file located in /etc/default/grub there is a setting called GRUB_GFXMODE you can set it to GRUB_GFXMODE=1200x900. Then you need to run sudo update-grub2.

Run vbeinfo in GRUB to see which graphics modes your graphics card supports.
