Problem with tablet pen cursor on dual monitor
Hello, I'm new to GIMP. I'm having the problem with pen cursor when i use dual-monitor.

Before I run GIMP everything work fine, The pen cursor can move in both monitors.
But when I run GIMP, It lock my pen area into only the main monitor, even if I close GIMP. So I need to restart my PC to use both monitor with my pen.

It seems to be fine locking pen cursor area in a single monitor, But GIMP cursor IS NOT CORRECT with pen cursor. They both should be the same, But they are not. As you can see in the photo.

I've tried changing the input mode for tablet to Screen and Window. But it still doesn't work.

Please help me, Thank you, Smile

PS.I'm running GIMP in Window 7 (32Bit), My tablet pen is Kanvus Life H85

RE: Problem with tablet pen cursor on dual monitor
Hmm...that is strange behavior. Maybe something to do with plug-in-play between gimp & your tablet or monitor selection.

For starters, check(ONLY CHECK/LOOK AT all below unless you know what you're doing) your settings for the monitor, what are your current settings at?:

"Control Panel > All Control Pannel Items > Display > Screen Resolution"
(to get there, right-click your desktop.)

Settings to check within gimp
1.
Brush dynamics (under toolbox settings of brush, whether it is on or off)
2.
Edit > Prefrences... > Display
3.
Edit > Prefrences... > Input Devices
-Expand (+) and look at "Input Controllers"

You have two columns "Available Controllers" & "Active Controllers"
1.Click your device under "Active controllers"
2. Click the wrench icon below to configure it/check settings.

Update us on your findings Smile

My main display's resolution is; 1366x768
And second display's resolution is; 1360x768

My GIMP Settings
1. Brush Dynamic; Pressure Opacity with default value, I didn't change anything.
2.Display; Monitor Resolution; Detect automatically (currently 96 x 96 ppi)
3.Active Controllers. I already plug-in the tablet, But it's not show here.
- Main Mouse Wheel - State; Enable - Dump event for this controller; Uncheck
- Main Keyboard - State; Enable - Dump event for this controller; Uncheck
Both are default event value, I didn't change anything too.

Ok, great! I think we're getting somewhere, in this case maybe gimp isn't detecting your tablet correctly across multiple monitors.

*Still, the below instructions are meant to troubleshoot/check, the bottom link might have a solution.

Posting attached image
below this post, click "New Reply" at the bottom right. Then along with your reply scroll to the Attachments section below:
-click "choose file" then click "Add Attachment" (do this process twice to attach the two below screenshots(highlighted in bllue) to your reply


This is so can see what your seeing (while tablet is plugged in/used in gimp),
can you post a screenshot of:
Edit > Input Devices... (this window)

and a screenshot of the window in:
Edit > Preferences > [+]Input Devices > Input controllers
(with both Available & Active columns visible)

=========

I found a similar problem online that also suggests looking into the "Input devices" in preferences.
Maybe you can find a solution from this if the above deosn't work.
Exceprt : "the tablet wants to span the whole aspect of the screen..."

RE: Problem with tablet pen cursor on dual monitor
Here are two windows you were talking about.

   

   

Well.. I still can't find the solution.

---------------- EDIT ------------------------

Well.. This is not only happen in GIMP, but also happened in Synfig too.

Or this could be the problem with OpenSource's shared pointer? Because Photoshop and Flash can work normally even if the cursor still work in the main monitor.

RE: Problem with tablet pen cursor on dual monitor
Ok great, sorry for the late reply, looking at the "configure input..." window I think this might work if you haven't tried it already. It does recognize your device there as it is displayed.

Now
2 things to try:
1.
Go back to that window with your tablet plugged in "Edit > Input Devices..."
- see the "mode: Screen[v] Curve X" ?
Click the pull down and try "window" , then click save. Does it work correctly now?

2. You may need to add the device, this window should should show the tablet on the left side
- Go to back to "Edit > Preferences > [+]Input Devices"

-on the right side of the window look for a "configure extended input devices..." click it
The window should look like this (maybe exactly): [Image: attachment.php?aid=2528]

Change the "mode:" to "window" then click save.
Check if the device was added in the "Available controllers" or "Active Controllers" in
Edit > Preferences > [+]Input Devices > Input controllers
If "Tablet, Porth:HID...." show's up in the "Available controllers" column, click it and click the green arrow >, to add it/activate it to the "Active column"

Thats all i have time for at the moment, I'll reply back to any of your next replies Sunday night. Good luck!

RE: Problem with tablet pen cursor on dual monitor
Thank you, It's getting a bit better. Even if the cursor isn't work correctly, But it's more accurate than it use to be.

It has a problem when I draw around the rim of workarea on zooming like this. To prevent the problem I need to zoom to 100% or less.

   

Oh, The device still not display on the Availabe Controller.

My friend got a graphic tablet (Wacom) and work on dual monitor too, She doesn't has problem like this. I think the problem may relate to the device or the driver itself.

Thank you anyway. Big Grin

No problem, yeah Try zooming out a little more maybe 70% so you can see the pasteboard(the grey space outside of the workspace/drawing area) & see if that works.

I also have a waccom, it seems to be most compatible with that brand of tablets(Gimp) so you maybe right about the device compatibility. So you might want to try to get a waccom tablet.

One last questions/check you can do.

Do you have a laptop with a touchpad mouse you can disable? Do you have a usb mouse(wired or wireless/infrared) mouse plugged in?
-Try to temporarily disable the mouse if its a touchpad(there should be a button/gesture to turn it off) or if plugged in, unplug it / temprarily disable the usb mouse in wdoze Device manager if possible(will reduce wear&tear from unplugging and plugging)

*If you do the diasble the usb mouse via Device manager, don't have the tablet plugged in until after you disable the mouse (that way you won't accidentally disable the tablet)
-sometimes the mouse is linked with the tablet, but it doesn't hurt to try.

Good luck Smile

RE: Problem with tablet pen cursor on dual monitor
Sorry for a very late reply, I've been busy for a while.

- I'm not working on the laptop, So I don't have any touchpad or an external touchpad.
- Yes, I have a wired mouse plugged in.
- I have tried unplug the USB mouse and then plug in the tablet. But the problem is still the same.

I think I should buy a new graphic tablet, Haha.
Thank you for your help. Smile

RE: Problem with tablet pen cursor on dual monitor
Hi there!

I've been having the same problem. I have a Kanvus Artist 127, using GIMP 2.6 (2.8 didn't work that well with the pressure sensibility with my Tablet). I'm on a n old HP Pavillion laptop with res 1440x900, attached a Dell monitor at 1650x1050.

At first I thought it was the different res'es causing me to have the exact same problem (pen draws lines to the left of the pen (not the right as in your case)) but since you're having the same issues with the same res, I do wonder what this is. It wasn't always like this - I'm yet to try a restart, which might fix it. Because what happens is even if I unplug the tablet, close GIMP, then set my monitor to Main, plug in the tablet, open GIMP, GIMP seems to load in the laptop (secondary) window. (It loads the pencil tool window in the correct window, but loads the 'main frame' on my laptop. So what I think this is is GIMP doing something funky when interpreting the monitors. It only messes up the pencils and brushes anyway, I can still use the pen fine to resize windows, close them etc. (I've fiddled around with the tablet driver options in GIMP, no success.)

I fixed the problem by setting the Screen options on Windows (I'm on Windows 7, b y the way) to 'show desktop only on 2' (my Dell monitor). It now works perfectly - however I'm one screen short for references Dodgy

Hey mcoolwine,

Are you still having the issue?

If you haven't fixed it, I found another solution helping another user who had a similar problem on this forum. Its worth a try/look

- Read the first 3 or 4 posts here (this user has the same exact problem)

RE: Problem with tablet pen cursor on dual monitor
I just dumped two hours into this issue! I'm running Gimp 2.8, Win 7, with a cheapo Huion tablet. My workaround is as follows: move gimp to second monitor, set the tablet to be mapped only to the second monitor, and in gimp set the tablet mode to screen.

(in other words, fart around with the settings on your tablet/gimp until you find something that works!)

Setting the tablet to window in gimp gives the behavior the OP screencapped, and having the tablet mapped to only my laptop monitor makes gimp fail to register the bush on the screen.
