Status: New Owner: ---- New issue 516 by hpsMo...@gmail.com: XMonad and xmobar wake up too often and are consuming more battery power http://code.google.com/p/xmonad/issues/detail?id=516 What steps will reproduce the problem? 1. Start XMonad and/or xmobar 2. Check their wakeup frequency with powertop 3. What is the expected output? What do you see instead? About half year ago when I used XMonad for the first time the wakeup frequency was only 10 times per second, sometimes even less. Now it often gets to 100, especially in idle state. What version of the product are you using? On what operating system? Debian wheezy. XMonad 0.10-4+b2 from debian official repo. Are you using an xmonad.hs? Please attach it and the output of "xmonad --recompile". This issue is reproducible on my laptop with any configuration, including the default empty configuration. Please provide any additional information below. When there's an active X program running (like the chromium browser I'm typing in now), wakeup freq of both xmonad and xmobar are likely to drop to about 40/sec. But as keyboard and mouse become idle the freq rises up again.
