strange thing with the keyboard
I originally ran the 100 point calibration with varying success. I have been trying to run the 273 point calibration but kept running in to the reset the calibration message. It would not let me reset the calibration. I have now read about and tried unplugging the Keyboard, it will now let me run the 273 calibration! Very strange. There is also a problem with calibration retention. I do not seem to have the Wacom driver installed. I take it this is not installed as standard on the Pro 2?

Update: I did the 273 but with an intentional error in the central part of the screen. When the calibration was complete could verify that the calibration I had just done was in effect by observing the bad area in the centre. When I attached the keyboard the error disappeared and it reverted to a different calibration that I had miss -calibrated earlier in the bottom right hand corner.

The only alteration I have to this machine is renaming the registry key adding "User" before 'LinearityData'. I don't know if this registry change has any bearing on this scenario.

Wacom and 273 point calibration
Has anyone found a solution to using the Wacom Feel driver on the SP2 and using the 273 point calibration? I just tried it and the Wacom driver overrides the calibration. Btw, the 273 point calibration gives me a perfect pen accuracy. Thank you!

Hi,

I have also been looking in to this and came upon another thread (cannot post link unfortunately, google: can-you-help-solve-this-surface-pro-2-wacom-driver-mystery) with an update from Wacom. Basically, the Wacom calibration does indeed remove/overwrite the Windows calibration:-

"Its probably due to the fact that when the Wacom driver is installed we clear the 16 point calibration (the MS one that specifically accounts for corner & edge performance) and only allow the 4 point. The 16 point calibration interferes with Wintab accuracy across the whole screen, so we do sacrifice some corner accuracy. It does look like that is in our buglist as a feature enhancement (re-allowing 16 point or replacing the functionality, we do have a way to do it that will at least fix the edge performance in non-wintab applications, but we'd like to find a way to fix it for all use cases).

I'll get back to you once we have firmed up our schedule for our next release. 7.1.3-X should be out before the end of the year."


So hopefully this issue will be corrected when their next driver is released before the end of the year.

HTH.

Thanks,


Jason.

Thanks a bunch!
This calibration has worked wonders for me.

After removing the newest Wacom drivers, the calibration worked. Now I have to get used to writing normally again instead of a few mm off.

Originally, when I removed the drivers, my pen stopped working completely. A simple windows update fixed that.

I was wondering if people could help me. I ran the calibration and it worked great and then the right side of my screen got WAY off calibration wise. I reset and when I go and try to run the calibration program again it gives me an error and says Linerity calibration data is already presnt. Please use the "reset button" in the tablet pc settings control panel applet to remove the data.

However, I already did.

Also, is when I did my registry search, I did not find LinearityData, but I had already had a file called UserLineraityData. Is that ok?

Is there something I can do short of a reinstall of things?

THANKS A LOT!
I actually have a Lenovo ThinkPad Yoga, but it's working fine here aswell
Additionally for some more accurancy on the edges I added some coordinates
Code:
tabcal devicekind=pen lincal novalidate XGridPts=10,30,60,90,110,135,160,260,360,460,560,660,810,960,1110,1260,1360,1460,1560,1660,1760,1785,1810,1830,1860,1890,1910 YGridPts=10,30,60,85,110,135,160,250,400,540,680,830,920,945,970,995,1020,1050,1070
And by the way, if you're having trouble, that tabcal couldn't be found, try to open cmd.exe as an administrator

Greetz

Edit: for some reason, my overkill coordinates won't get accepted... maybe a little too much for the poor PC

Good news: I have found a solution to enable us to calibrate stylus with user-defined grid when Wacom feel driver has installed on your surface pro.
The trick is to edit the registry and no risk at all if you do it properly. Most of surface pro users experience LinearityData error when run the script:
tabcal lincal novalidate XGridPts=0,30,50,150,350,650,945,1240,1540,1740,18 40,1890,1919 YGridPts=0,30,50,150,350,630,830,1030,1050,1079.
Note that delete 'devicekind=pen' in the script(the script above is an example) does not solve the problem most of the time.

The solution is to delete the [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\H ID\VID_045E&PID_0799&MI_01&Col03\8&2d6be41e&3&0002 \Device Parameters], [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\TabletPC\LinearityData] and [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\TabletPC\UserLinearityData] using your registry editor.
Note that the id "VID_045E&PID_0799&MI_01&Col03\8&2d6be41e&3&00 02" of the first key's name could be different on your device. A search in registry for LinearityData is suffice to find it.

Then you are able to run the 'tabcal lincal novalidate XGridPts=0,30,50,150,350,650,945,1240,1540,1740,18 40,1890,1919 YGridPts=0,30,50,150,350,630,830,1030,1050,1079' script.
In this step, the values in [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\H ID\VID_045E&PID_0799&MI_01&Col03\8&2d6be41e&3&0002 \Device Parameters], [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\TabletPC\LinearityData] and [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\H ID\VID_045E&PID_0799&MI_01&Col03\8&2d6be41e&3&0002 \Device Parameters] are updated.
Bingo! You get the same accuracy in the corners as the one without Wacom driver.
To backup the linearityData, use the registry editor to export these three folders(the first one is the most important). You can recovery to this profile whenever you want. Is that nice?
Now you can also calibrate your pen using the default 4 points calibration tool in control panel. It will add a secondary correction, which is good in some cases. And the corner accuracy will not be jeopardized by this 4 points calibration.
Enjoy!

Doesn't work for me, after entering 'tabcal lincal novalidate XGridPts=0,30,50,150,350,650,945,1240,1540,1740,18 40,1890,1919 YGridPts=0,30,50,150,350,630,830,1030,1050,1079' I get a command-syntax error..

There is an extra space in "18 40". Delete the space, then I think it will work.

Okay, now everything is fine, kalibration is still there after rebooting several times. But I took the grid, mentioned in the first post. It gives me a better corner behaviour. Thanks for the fix!

I get way better accuracy with only wacom drivers and no 273.
