Comment #7 on issue 515 by bmathiasen: XMonad freezes occasionally when using Gridselect (XMonadContrib) http://code.google.com/p/xmonad/issues/detail?id=515 Thanks for the elaborate response. Just to bring a status update: XMonad doesn't seem to freeze on Arch (hope i don't jinx it ;). Both systems have xmonad/+contrib installed through cabal and run identical xmonad.hs. Here's some output from 'X -version' on my two currently running systems, in case it makes any difference: Mint (debian) 'X -version': X.Org X Server 1.12.1.902 (1.12.2 RC 2) Release Date: 2012-05-19 X Protocol Version 11, Revision 0 Build Operating System: Linux 3.2.0-2-amd64 x86_64 Debian Current Operating System: Linux none 3.2.0-3-amd64 #1 SMP Thu Jun 28 09:07:26 UTC 2012 x86_64 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-3.2.0-3-amd64 root=UUID=6cdaef22-3035-4c99-af66-553e95dcd62e ro quiet Build Date: 20 May 2012 08:57:17AM xorg-server 2:1.12.1.902-1 (Cyril Brulebois <kibi@debian.org>) Current version of pixman: 0.26.0 Arch 'X -version': X.Org X Server 1.12.3.901 (1.12.4 RC 1) Release Date: 1012-08-03 X Protocol Version 11, Revision 0 Build Operating System: Linux 3.4.4-2-ARCH x86_64 Current Operating System: Linux bridgelinux 3.4.9-1-ARCH #1 SMP PREEMPT Wed Aug 15 18:59:31 CEST 2012 x86_64 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-linux root=/dev/sda1 ro quiet Build Date: 09 August 2012 10:04:44AM Current version of pixman: 0.26.2
