Making it easier to click icons in X
If you want to double-click on icons to launch something in X you may find it annoying to get it to work right. In LXDE you can simply set it up so that you only need to single click instead of double.From LXDE launch the file manager (sorry these pix are grayscale, still figuring out how to screenshot the framebuffer!)
Right-click on a touchscreen
Obviously if you have a touchscreen, it cannot tell what finger you are pressing with. This means that all 'clicks' are left clicks. But if you want a right-click, you can do it.
Just add the following lines into your InputClass of /etc/X11/xorg.conf.d/99-calibration.conf after the calibration section
Option "EmulateThirdButton" "1"
Option "EmulateThirdButtonTimeout" "750"
Option "EmulateThirdButtonMoveThreshold" "30"
So for example your file will look like:
Section "InputClass"
Identifier "calibration"
MatchProduct "stmpe-ts"
Option "Calibration" "3800 120 200 3900"
Option "SwapAxes" "1"
Option "EmulateThirdButton" "1"
Option "EmulateThirdButtonTimeout" "750"
Option "EmulateThirdButtonMoveThreshold" "30"
EndSection
This makes a right mouse click emulated when holding down the stylus for 750 ms.
