Hi guys. I have got issue with rotation of screen on linaro lubuntu which is installed on cubieboard.
First of all I tried use XRandR, but it doesn't work. When I use something like xrandr -o left, I have "RandR extention missing" and I haven't been able to solve this issue.
Then we tried to change xorg params. When I add option "Rotate" in 99-sunxifb.conf which is in /usr/share/X11/xorg.conf.d/ directory with param "CW" the screen is rotated, but mouse coordinate map is not. I attach video with demonstration of this issue and you can watch it for more clearly understanding of my problem. Also, this situation with another parameters which are "CCW" and "UD" I think, this may be for two reasons. First is uncorrect xorg configuration, second is problems with video driver. When I tried to do similar actions in cubiean with VESA driver it works correctly, but I have another problems: First of all VESA doesn't support OpenGl. Second I realized from VESA source code it doesn't support rotation. So I haven't got any idea how that worked.
So, I see three ways to solve this issue. First. Fix XRandR Second. Correctly configure xorg, but I don't know how is. I tried to write my own configuration files, but never a one doesn't work correct and xorg -configure doesn't work. Third. Change something in the drivers, but I can't understand what is.
So, can you advise or suggest something?
Best wishes. Boris.
Dear Boris,
I guess you've got the wrong group for help; cubieboard is not a supported platform for the linaro gpgpu group.
In any case, you might need to check what are the supported rotated mechanisms in the kernel that you're using. hope this helps!
Best regards, ~Sumit.
