** Description changed: Binary package hint: xserver-xorg-video-intel Dell Latitude D820 in docking station with one DVI and one VGA monitor connected. Before I upgraded to Jaunty from Gutsy, setting virtual to greater than 2048x2048 would automatically disable DRI. After upgrading to Jaunty, performance both with and without DRI was terrible. Tried xorg-edgers PPA and unofficial mainline kernel which fixed performance issues. With xorg-edgers PPA and the unofficial mainline kernel (v2.6.30.3), and virtual set greater than 2048x2048, xorg would exit when started, saying that DRI could not be enabled. Upgraded to the v2.6.31-rc6 kernel. According to http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.31-rc6/CHANGES it contains the fix "drm/i915: Allow frame buffers up to 4096x4096 on 915/945 class hardware". With this kernel, xorg starts when virtual is set greater than 2048x2048, but second screen is not enabled. Running xrandr (with virtual set to either 3360x1050 or 4096x4096 in xorg.conf): xrandr --output LVDS --off # must be done separately xrandr --output TMDS-1 --mode 1680x1050 --output VGA --mode 1680x1050 --right-of TMDS-1 xrandr: screen cannot be larger than 2048x2048 (desired size 3360x1050) xrandr --fb 3360x1050 --output TMDS-1 --mode 1680x1050 --output VGA --mode 1680x1050 --right-of TMDS-1 xrandr: screen cannot be larger than 2048x2048 (desired size 3360x1050) I'm also explicitly disabling DRI and DRI2 in xorg.conf.
