Linux Driver 1.3.5-35, input on wrong screen

I have been testing the 1.3.5-35 linux driver for some weeks now.  Overall it is working well. I just want to report two issues.

Device: PID_520A Pen Display 24
Driver: 1.3.5-35
System: Ubuntu 25.20.x86_64 6.17.0-22-generic

I am using Wayland and Gnome 49.

1. Scaling: The driver tool does not scale along with all the other apps. Thus on a high dpi screen the app is tiny. This is not a huge issue, but would be nice if it scaled correctly. I have two screens, on DP-1 I have an LG 1440p wide format monitor and on HDMI-1 I have the Pen Display. The pen display scaling is set to 1.5x in Gnome Settings so that both screens operate at a logical 1440p making it easy to use side by side. On the PenDisplay the XenceLabs driver app is tiny - as if ignoring the scaling - but crisp/sharp. Meanwhile moving it over to the LG monitor it stays at the same small size(!) and is additionally badly rendered - it is scaled down. Interestingly I cannot show this in a screenshot, because the screenshot captures it at full size - the way it really looks on my monitor is how the screenshot looks at 66% scale. This makes me think that the 1.5x scaling on the Pen Display is being applied as a 66% scaling on the LG instead.

Anyway, that is not a big issue for me. The next issue is far more annoying.

2. Ever single time I start up as well as every single time my monitor wakes up from sleep, the XenceLabs Driver treats the LG Monitor as the Display selected in "Device Settings / Display Controls / Cursor Placement". This means that any pen input to the Xence gets mapped instead to the LG monitor "Display 2(52110,0 6880x2880)" and I have to manually select the Pen Display "Display 1(0,0 5120x2880)".

Things to note:
- Nothing I do seems to change the default selection to Display 1, it always resets.
- The resolutions according to Gnome Display Settings are: 3840x2160 for the pen display with a scaling of 150% to make it behave like 2560x1440, and 3440x1440 for the LG at 100%. The LG is set as the "Primary Display" according to Gnome. 
- The resolutions reported in the Driver tool (5120x2880 and 6880x2880) are the doubles of the correctly scaled display resolutions.... so clearly something is off in the calculations here.

But bottom line: the driver works well enough and the pen input works well enough. Though I have not done any serious art/pen work recently - when I do I can provide better feedback - so for now I am only commenting on regular desktop use with occasional pen input for signatures for example.


thanks for the driver!

Thanks for posting that detailed review. I'm sharing it with the driver team.
