I recently bought a Dell Latitude XT and am now trying to get LMDE running at its best. Amazingly, the ntrig touchscreen worked right out of the box, but there are still some things I couldn't solve.
Corrupted letters in Cinnamon/OpenGL:
The X1200 IGP works ok for most parts, but some Letters are rendered in dotted lines:
This effect can also be found in e.g. the Server Browser of Teeworlds.What I already did is updating to the latest xorg-radeon from debian unstable ->no change and setting the sometimes proposed EXAPixmaps="off" Option in xconf->a whole lot more screen corruption. Any hints what to try next would be really cool.
Touchinput not rotating with the image:
If I turn the screen orientation, the touchinput will still use the coordinates of "landscape" mode. I am now using this which works for one rotation:
https://github.com/wolneykien/xrandr-align
One turn to the right works fine, but when I turn the screen back to landscape, the height coordinates are chopped down to half of the screens hight. To logout and login resets them to normal. Maybe someone can propose a script which does the input reset without a logout?
No vertical scrolling on touchpad:
It seems to be a known issue that the touchpad is only recognized as a mouse and therefore scrolling doesn't work. I can live with that, but a hint how to solve that would be nice none the less.

Rotation is solved .
Sometimes it's best to script on your own(based on this). This works great for me. You can also add the other pens like an eraser the same way as the stylus, only the Touch inputs need coordinate transformation:
Now the last thing on this front would be setting the rotation key to do this(instead of trying to turn of the touchscreen and not succeeding).

Code: Select all

rotation="$(xrandr -q --verbose | grep 'connected' | egrep -o '\) (normal|left|inverted|right) \(' | egrep -o '(normal|left|inverted|right)')"
# Using current screen orientation proceed to rotate screen and input devices.

Hi there
I too have the same problem - found these to guide you, though it seems no one has a fix - and no one is inclined to fix this for an older piece of hardware.

In Fedora I enable fallback mode, and this is ok

Re: Fighting my Dell Latitude XT (ATI X1200 probs)
From what I can gather, fallback mode does not fix anything but refrains from using 3D rendering. That's the same as just going to MATE(which I've done for the time being).
All in all, I have to admit that for now Win8(RTM) is my favorite OS on this hardware. With 3D text not working, there is no touch friendly menu available for any flavour of Linux.

Re: Fighting my Dell Latitude XT (ATI X1200 probs)
With cinnamon 1.6 the corrupt letters are "fixed" since there is a 2D mode.
Re: Fighting my Dell Latitude XT (ATI X1200 probs)
Are there no proprietary drivers for the ati? You say everything worked out of the box....
Re: Fighting my Dell Latitude XT (ATI X1200 probs)
The last ones are from 2009 and require an enviroment which is equally outdatet.
