--=-2ToGypo7kUfw+5KIUy1y Content-Type: text/plain Content-Transfer-Encoding: quoted-printable Hi all I've been using the intel xorg driver for quite some time now, and recently upgraded Xorg server/drm/intel driver to the most current available in ports. This has caused a significant performance regression when running without direct rendering enabled, which is required with this driver to achieve Virtual desktop with a dimension greater than 2048 pixels. Xorg now chews through 30-35% CPU whilst tailing a log file, where as before this used 3-4%. The effect is visibly noticeable (and doesn't just apply to fast moving text!) I have an HP laptop with a 1400x1050 LVDS panel, with a 1280x1024 TFT attached to the VGA port. My preferred setup is: xrandr --output LVDS --mode 1400x1050 --output VGA --mode 1280x1024 --left-= of LVDS What I am running now, the only way to get sane performance: xrandr --output LVDS --mode 1024x768 --output VGA --mode 1280x1024 --above = LVDS I've tried reverting back to an older driver, but it seems that changes to libdrm prevent that. I fear I may have to roll back drm, mesa, xorg-server et al just to use a different driver version. Any tips?
