I posted the same question to the Arch Linux forums (see here: https://bbs.archlinux.org/viewtopic.php?pid=1509943#p1509943, no response), but I have a problem where XMonad occasionally freezes and only the current window responds to keys and mouse clicks. I looked this up on the Xmonad FAQs, and apparently it's caused by a full pipe that I need to cat (https://wiki.haskell.org/Xmonad/Frequen … _frozen.21). However, this is a bit hard when the window that responds to keys is not a terminal. Is there a good fix for this? Also, if anyone knows what logs I should check for this problem in the future, that would be helpful as well.
