Bug#693025: xmobar: unable to read CoreTemp and BatteryP is blank on ThinkPad

[Martin Kjær Jørgensen]

Package: xmobar
Version: 0.14-3
Severity: important

Dear Maintainer,
I'm using xmobar with XMonad. When using CoreTemp in .xmobarrc i get:
"Prelude.read: no parse" instead of the core temperature.
When using BatteryP I get " 0%" instead of the actual <left> value.

I've tried purge the xmobar package from apt/dpkg, and installed xmobar 0.15
from cabal-install. cabal-install required several ghc packages to be upgraded
and warned me that it could break the xmonad.contrib package. I installed it
anyway, as an ordinary user, installed the new xmobar 0.15 and the CoreTemp
error disappeared and the BatteryP showed correct <left> value.

The cabal-intall package upgrades somehow did break my xmonad,
which all of a sudden could not find any namespaces (import's) when i
tried recompile (mod+q).

Removing the .cabal and .ghc dir's fixed xmonad recompile problem.

Forgive my ignorance. I'm new to haskell and xmonad.

Can you please attach the output of `cat /sys/bus/platform/devices/coretemp.0/temp1_label'?

Can you also attach your xmobar config, so that I can have a look at the
template you're using?

Thanks,
Apollon

Ok, this is a known bug fixed upstream in 0.15. I'll see if I can backport the
fix, it should be a non-issue.

Most likely you need to use the -c parameter for BatteryP to point it to the
correct file under /sys/class/power/<BAT>/, see the manpage for details and
give it a try if you can. 0.15 does some autodiscovery and doesn't need the -c
flag anymore.
