My problem is a lot of cpu is being used, as in the top output below:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 935 polkitd 20 0 158908 109304 4264 R 26.91 10.71 36:30.79 polkitd 413 dbus 20 0 3296 1656 1152 S 18.61 0.162 23:01.50 dbus-daemon 12150 root 20 0 43884 7808 5764 S 14.62 0.765 0:58.76 NetworkManager
When I systemctl stop NetworkManager.service, top now gives:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 413 dbus 20 0 3296 1656 1152 S 3.986 0.162 23:24.18 dbus-daemon 935 polkitd 20 0 160756 111436 4264 S 1.993 10.92 37:04.13 polkitd
Firstly, is this cpu usage normal? At this stage, I assume it itsn't. I've read a few bug reports, but a lot of them are beyond my knowledge. I'm not aware of whether there is a problem with networkmanager (if it is abnormal) but the high cpu usage of dbus-daemon (and maybe polkitd) is something to do with a program (presumably networkmanager here) asking them to do lots of pointless stuff. (Sorry, that's not at all clear, but that's the best way I can understand it!)
I'm on an old ThinkpadX40, and currently using LXDE. I did note that something similar also occurred here: https://bbs.archlinux.org/viewtopic.php?id=118028
At this stage, I'm hoping there is something I can do to fix this, and any help would be appreciated. (If you need any diagnostic stuff, please let me know the commands to get it = ) ) Otherwise I'm contemplating moving to wicd or netcfg, which I assume will be lighter anyway, but may also solve the above pickles.
EDIT: I moved to wicd (surpisingly easy!), and all problems are fixed. Not a solution to the original problem, but I guess I can mark this as "solved" given I've found an alternative.
