Surface Laptop 3 invalid product ID? #33

Closed Tim024 closed 3 years ago

Tim024 commented 3 years ago

Iptsd is not working out-of-the-box on my surface laptop-3

> sudo iptsd

Connected to device 045E:0984
ERROR: ../src/devices.c:286: Display size is 0!
: Invalid argument
ERROR: ../src/main.c:106: Failed to create uinput devices: Invalid argument

However, when I replace the device ID in /usr/share/ipts/surface-laptop3-13.conf (045E:0983) with the device ID thrown by the error (045E:0984), it works like a charm. Is it a typo or a different device?

StollD commented 3 years ago

It is probably a different device. I will add a file for the second device ID. In the meantime, if you dont want to edit the file under /usr you can also copy it to /etc/ipts.conf. That file has no check for the device ID and will always get loaded.

Didnt Microsoft release an Intel version of the SL3 with a 15" display? Do you maybe have that one?

Tim024 commented 3 years ago

Ah! Indeed after verification, I do have a 15" SL3 which explains the different ID.

This would be the correct configuration:

[Device]
Vendor = 0x045E
Product = 0x0984

[Config]
InvertX = false
InvertY = false

Width = 2496
Height = 1664

Thanks for the tip of using ipts.conf, I will do that in the meantime. Thanks a lot!
