Hi folks,

Is there a mailing list for tablet issues or tablet developers? I didn't 
see one. Indeed the mailing lists that aren't for developers seem to be 
for specific applications rather than the system itself. So, please 
forgive me if this is misplaced.

I've set up Gnome 3 from Debian unstable on a Panasonic Toughpad FZ-G1. 
This has /two/ sensor surfaces on the screen: a stylus that is or 
emulates a Wacom, and an eGalaxy Touch which is a multitouch finger 
touchscreen. Both are using evdev, the eGalaxy also has mtdev. Kernel is 
3.14 .

If anyone has tested this device with Gnome or indeed Linux, there isn't 
any web evidence. It works, with a few little issues that I am now 
running down.

The Wacom works correctly. The eGalaxy Touch mostly works, but something 
is different about the button events. On the screen keyboard, the 
buttons highlight when I touch them but they don't act as if they've 
been pressed. This also happens on all of the shell panel buttons. But 
finger-touch on a dock icon correctly launches the program.

In xev, button press and release events look identical between the two 
devices.

Nice to see that Gnome 3 is mostly usable on tablets. I can probably 
test multitouch when I get through this issue.

     Thanks

     Bruce
