Inconsistent drawing tablet support as a mouse input device #8026

Open ChildishhAlbino opened 1 year ago

ChildishhAlbino commented 1 year ago

Batocera used to support my Wacom Intuous BT as a valid input source for mouse input. Initially reported this an issue after Batocera V35 but closed due to belief it was a Retroarch issue.

I cannot get Retroarch to recognise this device in the Mouse Index option which I believed was a Retroarch issue. However, after some time installing older versions of Batocera - I've not been able to fix the issue and now think it's an issue with input on Batocera. I can however select my DS4 Touchpad as valid input for DS and 3DS games.

I do however get the cursor to move when using applications that show it - even the Retroarch overlay menu

When checking libinput devices - I get the below error message about my drawing tablet from any version of Batocera I've tried. V33 and newer.

[root@BATOCERA /userdata/system]# libinput list-devices
event19 - Wacom Intuos BT S Pad: libinput bug: missing tablet capabilities: pen resolution. Ignoring this device.

Wondering if installing something like input-wacom would resolve this issue for my specific tablet - but I wonder if there is a more generic solution for any drawing tablet that moves the mouse cursor.

On Windows - Retroarch just lists a Default option that reads any mouse input. Is something like that possible for Batocera?

i already got this bug (or a similar). it comes from libinput (or xorg, not sure) that is expected things from the devices while there are not true. (so here, probably a variable about the pen resolution). we can either remove that check if that makes sense or set the propriety via an udev rules i think. not sure i will work on it. but let's start. plug your device, and send a batocera-support file here (check in the wiki if needed)

Connected tablet via BT but i have the same issue regardless how it is plugged in.

here's the support file :D I've manually redacted my wifi network password - that's the only change made.

Just wanted to see if there's any support for this issue @nadenislamarre or somebody else?
