For some unknown reason Ksysguard suddenly doesn't seem to see any of my CPUs for the system usage graph. It still displays usage for individual processes and a total at the bottom of the screen, just nothing on the graph. If I open the properties for the graph and go to the "sensors" tab, there's nothing listed. Any idea how to fix this? Thanks!



Also, when taking the screenshot, I noticed that it's exactly the same for the network usage (nothing listed in properties window either). I am using a system monitor widget on my desktop and both of those (network and CPU) are working just fine. The network interfaces haven't changed names either...

Sounds like Ksysguard is having problems communicating with ksysguardd. When open, does ksysguard have a child process named "ksysguardd"?
