My panel plugin says "No Data". I have attempted to reinstall it (both reinstalling the slackpkg and completely unininstalling/rebooting/reinstalling it) with no success. I require further guidance in the resolution of this issue. I power down my computer at the end of the day every day and turn off the power strip, if that matters.
Ask in the forums of your linux distribution then. This is for reporting specific bugs, not a community help forum. Installing 0.8.11 or 0.9.1 from the newer gtk3 branch might help. Closing resolved invalid.
