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).

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.

Only difference I see is that you have 7 users.
