Strange process -:0


When running w I get a strange process -:0
Code:
 17:53:47 up  1:25,  7 users,  load average: 1.31, 1.16, 1.22
USER     TTY        LOGIN@   IDLE   JCPU   PCPU WHAT
richard  :0        16:38   ?xdm?  12:07   0.03s -:0
What can this process be?
Why the ?xdm? for idle value?

Also since installing my new USB 2.0 controller I find that I'm having a bit higher load average. At least I think it has to do with that installation. If my mind doesnät play tricks with me I used to have well below 1.0

Is there a good way to pinpoint what is causing the high load?
I know there is more to it than the cpu load (I/O etc)

It's your login from X. You can check with "echo $DISPLAY"

That's quite a load average, are you running some programs?
Code:
markus@mrk-fujibox:~$ w
 19:44:24 up  1:22,  1 user,  load average: 0.09, 0.15, 0.11
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT
markus   :0       -                18:24   ?xdm?   5:05   0.01s -:0
What does top look like?

Nothin unusual shown in top, as far as I see.
The CPU isn't working on a high load, seems to me that it lies elsewhere, like in the I/O system or with kernel modules.
I know that I'm a bit low on memory (256MD DDR) for my AMD Athlon 1400 running Suse 9.0 with KDE (4 desktops).
Code:
top - 19:16:29 up  2:48,  7 users,  load average: 1.18, 1.13, 1.09

No disk swapping activity, other than when starting new programs.

Is there any way to see how much the individual open files/sockets etc use in terms of CPU power, I/O time, idle time?
Could this info be monitored using lsof?

Sorry, not a clue about checking single sockets.
For comparison I'm running debian unstable, 256 MB RAM, Celeron 1000, 2.6.9, KDE.

Code:
top - 20:32:02 up  2:10,  1 user,  load average: 0.44, 0.82, 0.77
Tasks:  60 total,   1 running,  58 sleeping,   0 stopped,   1 zombie
Cpu(s):  9.9% us,  3.0% sy,  0.0% ni, 86.8% id,  0.0% wa,  0.3% hi,  0.0% si
Mem:    255136k total,   252652k used,     2484k free,    17640k buffers
Swap:   811240k total,        0k used,   811240k free,    91000k cached
Only difference I see is that you have 7 users.
