I can't run "/usr/bin/Xorg -keeptty -dumbSched" because of my "dualseat" configuration. I've done backtracing using second "seat" connected to the proper X server process with audacity... And I've discovered that I can use KDE and some other X applications on second Xorg server/display/"seat" without problems while the Xorg CPU usage is near 100% on first "seat". On the first seat work with X apps is almost unusable then (over few seconds to wait for click/window refresh etc.).
