Re: [Linux-fbdev-devel] Linux fbcon.c

Thanks a lot for your fast answer!!!

	Would you mind sending me your code, cos at the moment my screen is
pretty much screwed up, but not rotated. 

I just tried to rotate the *s on putcs. last to first and mirrored every
byte. 
Result--> mixed up screen color and chars. 

As far as I figured, the *s holds a bunch of bytes for the video_mem. 

Regards Florian
