Pynput crashes on openSUSE LEAP 15

[TheLastProject]

I believe this may be related to Wayland, although I have been told that LEAP 15 uses XWayland.

See Pext/Pext#168 for more info.

Any way I can help debug this?

Thank you for your report. Do you have more details, such as a stack trace? As a side note, pynput in not very useful under XWayland, as interactions seem to be limited to other applications running under XWayland.

The stack trace is in the linked issue, I'm pasting it here for completeness:

This error is not only for OpenSUSE. I'm having the same issue on a Ubuntu machine as well, I'm using virtualenv with the 1.6.8 version (based on the same stack-trace placed above)

EDIT 1: I was checking the limitations resource but I'm confused about the X Server and the $DISPLAY variable. By ps -e | grep X I got:

2367 tty1 00:00:00 Xwayland
6306 tty2 00:23:50 Xorg
17941 ? 00:00:05 VBoxXPCOMIPCD

My display variable is :0

EDIT 2: I just noticed about the Wayland incompatibility, this affects the GNOME3 directly, so the Ubuntu family can't use this package, am I right?

Thanks in advance.

Even im facing the same issue here (ubuntu 16) . Can anyone please suggest me to log long key press . Or any other module where i can log long key press . ? Thanks in advance

@TheLastProject, did you have a look at this post? This error could be caused by a bug in python-xlib, and is said to be solved by issuing xhost + in the terminal.

@davidlares, @mohammedyunus009, If your problem is running under Wayland, a possible solution would be to use the uinput backend. You will find more information here.

In any case, this appears to be a bug in a dependency with a known workaround, so I will close this issue.

Can confirm the issue on openSUSE and the xhost + fix do you know of a bugreport in python-xlib so I can look at getting the fix?
