Issue 474 in xmonad: XMonad does not respond to keyboard input when there is a lot of I/O occuring in a terminal
Status: New Owner: ---- New issue 474 by cmcbr...@rjmetrics.com: XMonad does not respond to keyboard input when there is a lot of I/O occuring in a terminal http://code.google.com/p/xmonad/issues/detail?id=474 What steps will reproduce the problem? 1. cat /dev/urandom in a terminal emulator (I'm using 'terminator') 2. CPU usage is only around 20% however xmonad is completey unresponsive to mouse or keyboard input. It usually takes a while to gain control again. What is the expected output? What do you see instead? Xmonad would handle this gracefully. What version of the product are you using? On what operating system? Xmonad 0.10 and Debian Linux, kernel 2.36 liquorix Are you using an xmonad.hs? Please attach it and the output of "xmonad --recompile". Please provide any additional information below. Attachments: xmonad.hs 2.8 KB

That said: Terminator is mostly in Java, and Java's known to play badly with xmonad and non-reparenting window managers in general; the setWMName call works for some but not all JDKs, and there appear to still be some oddnesses around the latest JDKs with xmonad.

When I get a chance I'll try to reproduce this on a stock kernel.

That said; I've only got 2.6.38 and 39 kernels available. If I get a chance I'll try with terminator, and try a 2.6.36 zen (liquorix) kernel. I use pretty much default zen kernel settings, which AFAIK is what liquorix uses, although it also builds many modules. So I'm doubting the kernel is the problem. What sort of hardware are you testing on, cmcbr...?

I have 8gbs of ram. Quad-core intel Core(TM) i5 CPU@ 3.33GHz
