The interactive bonus may interfere with fairness (the throughput bonus should actually help it for tasks with equal nice) so you could try setting max_ia_bonus to zero (and possibly increasing max_tpt_bonus). With "eb" mode this should still give good interactive response but expect interactive response to suffer a little in "pb" mode however renicing the X server to a negative value should help.
Peter PS There's a primitive GUI available for setting the scheduler parameters at <http://prdownloads.sourceforge.net/cpuse/gcpuctl_hydra-1.3.tar.gz?download> this is just a Python script with a Glade XML file (gcpuctl_hydra.glade) which needs to be in the same directory that you run the script from. -- Peter Williams pwil3058@bigpond.net.au
