[xmonad] Starting Audacity under Xmonad triggers end of user session

[Josiah Schwab]

Hello,

I am using xmonad on Arch Linux on a ThinkPad X1 Carbon (Gen 4).

Over the past few months, I have occasionally had issues where my X
session suddenly ends and I am dumped back into my display manager.

There is no relevant information in /var/log/Xorg.0.log.old, simply the
line

    [ 4566.334] (II) Server terminated successfully (0). Closing log file

The only relevant lines I see in the journal are:

    Jan 17 08:26:55 monolith lightdm[31036]: pam_unix(lightdm:session): session closed for user jschwab
    Jan 17 08:26:55 monolith org.a11y.atspi.Registry[31192]: XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
    Jan 17 08:26:55 monolith org.a11y.atspi.Registry[31192]:       after 885 requests (885 known processed) with 0 events remaining.


I finally found a 100% reproducible case, which is to launch the program
audacity.  I confirmed that this issue occurs using the example xmonad
configuration shipped with the Arch Linux package
(/usr/share/x86_64-linux-ghc-8.0.1/xmonad-0.12/man/xmonad.hs).

I suspect that xmonad is at least a contributing factor, because I
installed another window manager (openbox) and confirmed that the
problem does not occur there.

I also confirmed that the issue occurs with the xmonad-git and
xmonad-contrib-git packages, which track master on GitHub, so this
hasn't been fixed since 0.12.

Does anyone have any suggestions on how to track down the source of this
problem?

Josiah
