There are two drivers in the linux kernel that use similar protocols (different bit masks): touchright and penmount. I'm gonna modify touchright. For now I'm going to call it "SMK" although the chip could be from another vendor.

Alright, got some success, but it's not really useful at the moment due to the fact that the cursor is bouncing around quite a bit and there is a middle horizontal and vertical area where the cursor goes opposite of the pen.

Is there an alternative to evtouch? Right now inputattach makes the TS appear as a mouse. Shouldn't it be dev/input/ts0 ? Calibration with evtouch doesn't work.

Where can I upload the .tgz with the patches?

Nevermind, somebody who shall remain unnamed blew the fuse to the TS chip, which caused the TS to behave erratically. Fixed and it's working like a charm now.

Calibration was a pain: the evtouch program seems to calibrate, but then doesn't write anything to the file. I did use it to find the min/max which I entered in xorg.conf, then added Option "x0" "3" and so on for y0, up to x8,y8. Beware that x0,y0 is lower left, x2,y2 lower right, and x8,y8 upper right. The parameter is by how many pixels to move the cursor to bring it under the pen. Positive X is to the right, Positive Y is down.

Yee gods that was a nice bit of work. Fair play for getting that one figured out.

Driver and modified inputattach available at:

https://sourceforge.net/project/show...roup_id=211001

After this gets merged in the kernel I will remove the project from SF.

Cheers

thank you very much for your work
i can't wait till the kernel merges the patch!

If you're familiar with patching the kernel and don't want to wait, you can download the driver from the link in the previous post.

Hi,

Thank you very much for writing the driver for the touchscreen. If you would like to have it merged please send a patch with "Signed-off-by: ..." line to dmitry.torokhov@gmail.com and I will take care of the rest.

Thanks.

Okay, so I've installed Linux again. I've used Ubuntu before, and now I've installed it on my newly acquired Toughbook 73 (great deal on ebay for $487 shipped). After googling and searching the Ubuntu forums I came across this thread. I'm glad to see a driver for the touchscreen, now my problem is I'm nowhere near knowing how to install it. Can someone point me in the right direction, or am I going to have to wait for it to be merged? I don't mind editing files newbies shouldn't edit, it's how we learn, this is a fresh install, if I botch something then I can always just install Ubuntu again.

i was wondering if finally the patch got merged in the kernel or still not..
and is it absolutely needed a kernel patch? can't we do with a driver only?
tnx

So, I'm basically a complete newbie to linux. I'm trying to install Ubuntu 9.04 on my CF73 and the touchscreen doesn't work. I understand that one of you made a driver that works for it? How do I go about installing it? Thanks

Bumping an old thread, but I pulled my CF73 out of storage since I have come back from Iraq and I would Like to know if anyone got the touchscreen working under Ubuntu?
