Thanks for the sysinfo -- I've merged it and opened a pull request for libwacom to add a data file for this device.

As for the inverted pen pressure, since this device uses Wacom's alternate vendor ID (2d1f) the issue is going to be in one of the generic input drivers or caused by an incompatibility with the non-Wacom pen. To debug this, you'll need to install the "libinput-utils" and "hid-replay" packages from your package manager.

Please first use the following command to check how the userspace driver responds to changes in pressure. It should print out data whenever the pen is touching the device. Check to see if the "pressure" value increases/decreases with increasing/decreasing pressure. Press CTRL+C to stop the command.

$ sudo stdbuf -o0 libinput debug-events | awk '/pressure/'

If the pressure issue is present in the output of the previous command, use the following command to check how the kernel driver responds to changes in pressure. It will ask for a "device event number" -- type in the number associated with the "stylus" or "pen" device (e.g. I might see /dev/input/event24: Wacom Intuos Pro M Pen in the list, so I would type in 24). Like the last command, it should print out data whenever the pen is touching the device. Check to see if the values change as expected. Press CTRL+C to stop.

$ sudo stdbuf -o0 libinput record | awk '/PRESSURE/ { print $7 }'

If the pressure issue is still present, it may be an issue of your non-Wacom stylus not being compatible with your device. Try running the following command to dump the raw events sent by the hardware. It will ask you to choose a device: select the device with Wacom, pen, or stylus in its name. It should generate output whenever the pen is in proximity (if it doesn't, quit recording and try again with a different device number). Touch the pen down and then slowly increase and then decrease pressure. Remove the pen, and press CTRL+C to stop recording. You'll need to attach the generated /tmp/isdv4-2d1f-002c.txt file to this bug for review.

$ sudo hid-recorder | tee /tmp/isdv4-2d1f-002c.txt

heres the file isdv4-2d1f-002c.txt the pen does seam to have the inverted issue with every command. aslo is there something i can do to try and get the other pen(actually a Wacom pen) i have to work?

Hmm, yeah, its definitely inverted here as well. The status ("Sta") bits also appear to be incorrect; its showing the tip and side-switch to always be held down, even when (presumably) hovering and not pressing the switch.

is there something i can do to try and get the other pen(actually a Wacom pen) i have to work?

You can try running hid-recorder again and seeing if any events are generated in response to the Wacom pen. I have a hunch that nothing will happen though. Not all combinations of pen and sensor are compatible, even they're both from Wacom. The tech that lets the sensor wirelessly read pressure and other data has gone though several revisions and they can't always work with each other.

I believe this might be the "official" pen for the 5190. I see a lot of negative reviews, even from 5190 users though. Not sure why the pen would fail to work... An alternative might be the Noris digital pen from Staedtler. The 5190 and tablets based on the same tech is mentioned in its compatibility list, and the pen has much better reviews on Amazon.
