The DE (KDE4) is severely lagging and experiencing seconds' delays in reaction to mouse/kbd events. So using the desktop is practically impossible. In `top`, the Xorg process consumes up to 100% CPU. When I switch to VESA driver, there is no DE performance problem (rendering and reactions almost instant, CPU usage by Xorg about 6-10%). I have exactly the same software versions installed on another PC but with nvidia hardware and x11/nvidia-driver, and everything works there fine, too. So I assume the problem is somewhere around drivers (either xf86-video-intel, or Mesa layer, or the i1915kms module). My system is: FreeBSD 9.1-PRERELEASE (GENERIC) #0 r240286: Mon Sep 10 14:27:33 MSK 2012 the latest Xorg from the xorg-dev trunk (xorg-server 1.12.4, xf86-video-intel-2.20.4) WITH_KMS=true WITH_NEW_XORG=true -- Best wishes, Yuri K. Shatroff
