Segmentation Fault when trying to use mouse.record(button='F2')

[jtara1]

Linux j-pc 4.4.0-83-generic #106-Ubuntu SMP Mon Jun 26 17:54:43 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux python 3.5 mouse Version: 0.7.0

my code

import mouse
def run():
    start_stop_record = 'F2'
    print('Press {} to start or stop mouse recording'
          .format(start_stop_record))
    events = mouse.record(button=start_stop_record,)
run()

edit: I realize now that the button is a mouse button, so something like 'left' or 'right' would be valid. Core problem still exists though I believe.

Sorry, the Linux part has seen little love recently. I'm just finishing some major changes to keyboard and Linux crashes will be the next top priority.

Thank you for the report.

The problem seems to be that in build_display() "display" is passed as C int to XDefaultRootWindow(). On platforms where pointers don't fit to C int that just doesn't work.

Here is a patch to fix the problem:
