I've done dpkg -P --force-depends xserver-xorg, rm /etc/X11/xorg.conf*, apt-get install xserver-xorg to get a completely default xorg.conf. I am attaching this here. This performance is only very slightly worse than what I get if I install the proprietary ATI drivers from ATI's web site using their ati-driver-installer-8.27.10-x86.run script. I run apt-get upgrade today and have dapper-security and dapper-updates in my apt.conf, so I should be up to date with respect to recent packages. My xserver-xorg is 7.0.0-0ubuntu45. My xserver-xorg-driver-ati is 1:6.5.7.3-0ubuntu7.
My D810 has a 1280x800 display. lspci -v | grep ATI shows 0000:01:00.0 VGA compatible controller: ATI Technologies Inc M22 [Radeon Mobility M300] (prog-if 00 [VGA]) I can provide additional information as needed. Just to be sure I'm not imagining things, I'm going to boot off of my old breezy live CD to make sure that X11 really does perform as I remember there. -- regression: poor X11 performance on Dell Latitude D810 https://launchpad.net/bugs/56100 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
