ts_calibrate with rotated display

roryhansen — Fri, 05 Apr 2013 15:53:09 GMT

We want to use our display in "portrait" mode. Our command in startx is:

Xfbdev -kb -screen 800x480@90 -mouse tslib,2,device=/dev/input/ts0 &

The display itself works fine, but ts_calibrate seems to ignore the rotate parameter, always running in "portrait" (non-rotated) mode. So therefore the touch screen doesn't work properly when @90 rotation is used. Without the rotate parameter, the touch screen work fine.

Any suggestions on how to get ts_calibrate working correctly with the display "rotated" on the i.MX28 EVM?

Thanks all!

Have you try to use the command "xrandr"?

1. export DISPLAY=:0.0

2. xrandr -q ( it will show out the screen information )

3. xrandr -o left ( it will rotate left )

4. xrandr -o right

No xrandr command with the MX28 linux kernel, don't see any way to build it in using ltib.

The screen rotation does happen with the "Xfbdev -kb -screen 800x480@90 -mouse tslib,2,device=/dev/input/ts0 &" in the startx script, but ts_calibrate doesn't seem to care that the screen has been rotated.

Would think this would be fairly easy.

AFAIK, 'xrandr' is part of X11 RandR extension so this binary should constructed when building X11, but I have not verified this.

The 'xrandr' library is there, which I assume is what "xfbdev" is using with the "@90" rotate parameter, but no actual 'xrandr' command (that I can see).

I also got what I believe is the latest, or at least newer, version of tslib, but still no difference.

It is X-Window and tslib usage. Maybe you can refer below link.
