HOW TO: Set up the HP TX2z and Dell XT & XT2 (N-trig digitizer) in Ubuntu

[wildschweini]

Great! I am glad to see that the swivel works with this version. Now we need to figure out what is happening with Ubuntiac's laptop.

I will have to say that it is strange that the left click does not work when touch is on. You wouldn't happen to know which N-trig firmware you are using in Windows?

thanks for the commands, Ayuthia, but the problem is to get the stylus pen fully running. it works after switching off the multitouch, but with enabled touch the stylus only turns the mouse arrow around and it seems that the left mouse click is kept all the time. i'm not able to solve this problem. running the program "xournal" turns the stylus' input working for a written text but nothing else. no clicks possible at all...

windows firmware is the newest available, i think. how to find out this?

Just to make sure that we are on the same page, the stylus will have the left-click on while the stylus is on the touchscreen. When it is hovering near the touchscreen, the left-click should be off but the cursor should still move. The button on the stylus should produce the right-click.

Another way to see what is happening is to use evtest. First you will need to know which /dev/input/event number the stylus is assigned. If you do not know this, you can install input-utils and then run:

sudo lsinput

and that will tell you what is assigned to the stylus. You will then need to go into a console (control-alt-F2 to go into console and control-alt-F7 to get back) because the wacom driver blocks information while X is running. Then you can run evtest:

sudo evtest /dev/input/event6

Replace event6 with the correct event number. Press control-c to exit the application.

Now, is this how the stylus is working or is the left-click on all the time even when hovering or is it doing something else?

Hi wildschweini,

Congratulations!


Touch on/off commands and touch toggle scripts are available at "5) Turning touch on and off" in the HOW TO. Since I think your using the evdev driver for touch you'd look in "b) evdev". But I'm hoping we'll be able to get everything working for you through Magick.

[Ubuntiac]

friendz, with Rafi's dell-wmi i tried to use the magick-rotation script and it works!!! .

Hey, if we can get wildschweini's working then we can try using the same stack on mine to see if it's the software or hardware/BIOS!

So wildschweini, I want to replicate your system as closely as possible on a spare partition. Would I be right in thinking you're using Ubuntu 10.10, 64 bit with nothing special other than the latest version of rafi's Dell-wmi with magick-rotation? Anything else I should know about? It would also be great to know what BIOS you're running. The XT says this under the big DELL logo when you first turn it on. It usually looks like A0 and then a number (ie mine is A03)

[Ayuthia]

windows firmware is the newest available, i think. how to find out this?

I want to say that the firmware might be listed in dmesg:

dmesg|grep -i ntrig

or

dmesg|grep -i 'n-trig'

In Windows, you should be able to go to the control panel and click on the N-trig stylus and touch. There should be an About tab or button that will provide the firmware version.

left click is ON already when hovering. no output for

$ sudo evtest /dev/input/event[#stylus]

interestingly, when switching back to X from console mode, the stylus isn't working even when i was in the 'touch off' mode before.

hey Ubuntiac. you're right, 10.10 64bit and nothing else the changed dell-wmi (and all recommended upgrades). the bios is A09...

@ Ayuthia:

$ dmesg

calls: Firmware 4.5.2.3.5 (1408 6540)

Ok. Can you provide the results of:

xinput list-props "N-Trig Pen stylus"

It will help us see how things are configured for the stylus.

They are exactly the same, whether the stylus isn't working in the first case.

[wildschweini]

i have to report on some problems that appeared after using magick-rotation for a while:

(1)
turning the lid to tablet mode for the first time works fine, even commands from the 'Advanced Setup'. but after turning back to laptop mode commands from the 'Advance Setup' like gconftool-2 --set /apps/panel/toplevels/top_panel_screen/size --type integer 24 don't work.

(2)
rotation to tablet for a second time (and all following) results in only rotating the screen but not the cursor. seems like

xsetwacom --set 'Device' bottomx/bottomy

or the

xinput set-prop 'Device' 'Evdev Axes Swap/Inversion'

don't work.

EDIT: this error appears only sometimes! there is no exact reason recognizable why.
