gkrellm process starts automatically without me indicate. In auto-run system preferences kde is not configured to start automatically, set at the time but removed it and just beginning the process continues in the background.
Can’t remember on top of my head, there is a setting in kde to start the last session.
If you set it to start without using the last session (fresh) it will not start gkrellm. Sorry can’t help much I am using xfce.
