I think I found the command to display my memory usage but I don't understand the difference between top and ps --user=root -f -u. The two output are completely different and apparently the processes using memory are root processes. How can I find out what they are excatly and if I can stop them from running? Any help would be appreciated thanks Meg Top Cpu(s): 4.3%us, 0.7%sy, 0.0%ni, 94.3%id, 0.0%wa, 0.0%hi, 0.7%si, 0.0%st Mem: 515712k total, 504592k used, 11120k free, 14980k buffers Swap: 1510068k total, 34744k used, 1475324k free, 203036k cached james@james-desktop:~$ ps --user=root -f -u Warning: bad ps syntax, perhaps a bogus '-'?

I have the desktop effects enables but compiz-real is only using 4.4% MEM and 0.2 or 0.3 CPU.
