[arch-general] VTs are unusable (too dim) after X starts

[didier gaumet]

No progress here on the front with radeon driver in non framebuffer
mode, but I have succeeded with non framebuffered vesa and with
framebuffered radeonfb VTs:
Vesa driver does not exhibit the same problem but is not accelerated
and defaults on this PC to 1280x1024, which is a 5/4 format that does
not fit very well a 4/3 screen.
So for the present being, VTs are framebuffered (grub2 loads vbe and
radonfb, radeonfb is uncommented
in /etc/modprobe.d/framebuffer_blacklist.conf). X is not framebufferd
though: radeon module is still loaded too.
