Not only did it not capture the random pixels, but the image wasn't even inverted! :-) What I've done is made an image that shows you what I see. Note, this is not the real image, it's just a simulation. The first is after doing the rotation, the second is trying to drag a window over the random pixels (I can't). This is with a VGA LCD monitor. I haven't tried our LVDS display yet, maybe they won't show on the LVDS display, because they seem just a little off-screen. >>In addition, if I try to use Ctrl-Alt-Fn to switch back to a text > screen, the screen goes black (no signal). > > [Cui, Hunk] I will try to reproduce this phenomenon in my platform. Thank you > for your reminder. Ok, I had a look, and this happens if I'm using fbcon, the kernel's framebuffer-based virtual console. If I add "vga=792 fbcon=rotate:2" to the kernel boot command line, I get a nice rotated fb console, but I can't see text when I switch away from X. If I have the normal text console, I can see text when I switch away from X. The most important thing for me is the rotated screen, which I now have, thank you. It's ok if we can't switch VTs, for the moment. If there's something more I can do to help find the problem, or you need more information, please let me know. Mitch.
