First, I've enabled Option "ModeSwitchMethod" "new" in xorg.conf - restart
and nothings changed. Everything is as it was.

As in the instruction above I've edited /etc/default/grub with:
GRUB_GFXMODE=1024x768 (also tried 0x117)
sudo update-grub (also tried update-grub2)

After reboot, grub is still in 640x480. In grub comandline I use "vbeinfo"
and it says that 1024x768 is available (like other modes up to 1920x1440)
but it's using 640x480. Like my changes goes to hell.

The key to resolve this problem is to figure out what special "vga=791"
does, and to adopt it to grub2 or figure why X server is trying to use
1920x1440 by default (matrix is only 1024x768).
