 |
|
I can't get System Monitor to display the disk usage graph. However, when logged in X as root, it displays fine.
Does someone know where System Monitor fetches the information, and if setting a permission is required for users? |

I don't use Gnome, but I am guessing it gets its information from hal. Try adding your user to the 'haldaemon' group `gpasswd -a <user> haldaemon`

I made a mistake when I noticed I/O in the System Monitor applet as root. I was probably using a non-RAID device at that time, because the problem is that System Monitor doesn't pick up I/O from RAID (MD) devices. The problem lies in the gnome-base/libgtop package, which reads the wrong fields of the /sys/block/md*/stat files.
I submitted a patch upstream, but for anyone who stumbles upon this post looking for a temporary solution, here's my patch :
