title: xmobar on debian SID

If you are using "xmonad":http://www.xmonad.org/ and "xmobar":http://code.haskell.org/~arossato/xmobar/ on "debian SID":http://www.debian.org/ on a laptop, and don't see any battery information, you may have test this "solution":http://5e6n1.wordpress.com/2009/03/30/xmobar-battery-plugin-using-sysfs-not-procfs/.
If this didn't solve your problem, try this patch on SysfsBatt.hs :
{% highlight haskell %}
52c52
< let path = sysfsPath ++ p ++ "/charge_full"
---
> let path = sysfsPath ++ p ++ "/energy_full"
62c62
< let path = sysfsPath ++ p ++ "/charge_now"
---
> let path = sysfsPath ++ p ++ "/energy_now"
74c74
< else showWithColors (printf "%.2f%%") stateInPercentage
---
> else showWithColors (printf "Batt: %.2f%%") stateInPercentage
{% endhighlight %}
Then as before:
{% highlight bash %}
runhaskell Setup.lhs configure --user
runhaskell Setup.lhs build
runhaskell Setup.lhs install --user
{% endhighlight %}
Battery information should be visible.
