I was trying to get this drawing tablet working on Ubuntu 24.04 with X11 cloning a 4K display onto the drawing tablet (HD resolution so scaling the display down).
From what I was told on this forum, X11 didn’t handle scaling of windows to different resolutions well. I installed plasma-desktop-wayland to try that and still could not get the drawing tablet to clone the 4K display.
I did a clean install of Ubuntu 24.10 to get to a more current version of plasma-desktop-wayland and am now at version 6.1.5 and still cannot get the tablet to work.
The tablet works fine as a stand-alone additional display and the display is properly scaled.
However, I picked a 4K display as the target display in drawing tablet settings, and tried both Fit to Output and Fit Output in Tablet.
No matter what I do, the tablet never mirrors the 4K display, it still acts as an independent display.
I have the XP Pen drivers installed. If I click buttons on the tablet or on the pen, they are recognized by the XPPen driver.
However, when I drag the pen over the tablet screen, the cursor always tracks on my primary 4K display regardless what I pick as the target display.
Am I missing something or is what I’m trying to do just not possible?
I have this working now. I found that I could mirror my 4K monitor display on my drawing tablet by dragging the drawing tablet widget over top of the 4K monitor widget in the display configuration page and then setting scaling for the drawing tablet to 50%. I also have the area setting in the drawing tablet settings page set to fit output in tablet.
I found that I had to set the settings for XP-Pen-Pen in the same settings page to the display I was mirroring and set area to fit in tablet.
That got the tablet to mirror my display and the pen to control the cursor. Once I figured out some settings in the XPPen configuration utility, the pen was tracking properly across the entire screen area.
So this is solved I think.
