I'm sitting here playing some OpenGL games, and thinking, isn't it rude of processes demanding the same amount of cpu, when I am here, wanting the smoothest possible OpenGL experience. So I am renicing. But my knowledge of the kernel is limited. So I was thinking, maybe some of you could inform me, which processes are involved in getting the graphics on-screen. I have already started making a renicing script. --- highpri=-20; lowpri=19; for pid in `pgrep ""`; do renice -n $lowpri -p $pid; done #ubuntu runs a lot of processes that can be put in the background. for pid in `pgrep "init"`; do renice -n $highpri -p $pid; done #probably good to have high priority? for pid in `pgrep "kthreadd"`; do renice -n $highpri -p $pid; done #does drivers or anything else create kernel threads that are involved in the graphics on-screen? for pid in `pgrep "ksoftirq"`; do renice -n $highpri -p $pid; done #surely these are? for pid in `pgrep "X"`; do renice -n $highpri -p $pid; done for pid in `pgrep "metacity"`; do renice -n $highpri -p $pid; done for pid in `pgrep "hd-audio0"`; do renice -n $highpri -p $pid; done -- Comments and information appreciated. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
