here i will collect all information about what scripts or tools to use to get to a nice working overall experience...
currently i use the proprietary nvidia drivers. to get the newest version have a look at the graphics-drivers ppa a good read is this askubuntu answer.
for now i use ICC Brightness for me this works on the main screen only. for additional info have a look at issue #1 - screen brightness
copy config
sudo cp 99-touch_pen_input.conf /usr/share/X11/xorg.conf.d/
this setups the touchscreens to work on there own screen-area. and setups the pen input to be handled by the wacom / Graphic-Tablet driver. the IDs are submitted to the libwacom team. but it can take some time till it lands in the official packages... if you want to try directly copy the two files
- elan-29b6.tablet
- elan-29a1.tablet
to
/usr/share/libwacom/
as described in the wiki
$ echo -e "\n# setup firefox multitouch \nMOZ_USE_XINPUT2=1\n" >> ~/.profile
if enabled the content will not scroll with a mouse-wheel on 'not active' windows.. this is a known limitation/bug.
for KDE you don't need any fancy tools for the window screen management: it offers keyboard options to move the current window from one to the other screen. i have added the 'toggle screen' key to Window to next Screen this results in toggle if only the two screens are active - and moves the window through all screens if an 3 external screen is attached...
i don't know if gnome has similar things out of the box..
