[PLUG] Why does my computer seem to be running slow?
For some weeks I've been experiencing "slowness" with my Xubuntu box and with my Linux Mint box. I know I can run top to see what programs are using resources, but I don't really understand how to make use of that, since there are programs I don't recognize. Also, while typing this (on my Linux Mint box) all the entries for open windows disappeared from the panel, and I have two error message boxes. One says: "Show Desktop" has quit unexpectedly. If you reload a panel object, it will automatically be added back to the panel. And the other one says: "Window List" has quit unexpectedly If you reload a panel object, it will automatically be added back to the panel. Each error message has three buttons: [Delete] [Don't Reload] [Reload] Clicking [Reload] on the second box restored the entries on the panel. Clicking [Reload] on the first box didn't appear to do anything. What does all that mean? Meanwhile, top says I have a zombie. What do I do about that? top - 08:43:46 up 3 days, 22:55, 1 user, load average: 0.47, 0.73, 1.38 Tasks: 219 total, 2 running, 216 sleeping, 0 stopped, 1 zombie %Cpu(s): 4.4 us, 10.5 sy, 1.6 ni, 83.3 id, 0.0 wa, 0.0 hi, 0.2 si, 0.0 st MiB Mem : 7865.4 total, 1060.9 free, 3791.2 used, 3013.3 buff/cache MiB Swap: 2048.0 total, 1408.5 free, 639.5 used. 3359.7 avail Mem Sigh.
