I have now found out that I seem to be a victim of this bug: [Bug 47007] HDMI monitor polling causing 100ms rendering stalls https://bugs.freedesktop.org/show_bug.cgi?id=47007 When I 'echo N >/sys/module/drm_kms_helper/parameters/poll' things get MUCH better! However, now the HDMI hotplug doesn't work anymore. My HW is a RS780 on Gigabyte GA-MA78GM-UD2H mainboard. As far as I understand the bug's audit trail, what I observe would indicate that the manufacturer didn't connect the hotplug pin properly. Is there anything else I can try to disable polling and still have HDMI hotplug? I really need that, because when my AVR is off, there is no EDID and thus I can't launch X. So whenever I turn the AVR on/off, my X session will follow. -- Regards greg _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
