Public bug reported: Binary package hint: xserver-xorg-video-intel
When setting the virtual desktop size to greater than 2048 in either direction (necessary for multi monitor support using xrandr), the intel driver disables direct rendering, thus disabling desktop effects. See: http://www.thinkwiki.org/wiki/Installing_Ubuntu_6.06.1_on_a_ThinkPad_R60e#Intel_945GM_with_the_xorg_Intel_driver >From the article: It is a limitation of the Intel driver that frame buffer size cannot be changed once X has started. Therefore in order to hotplug a variety of screens this should be set the allow for the largest combination of display resolutions you plan to use. For the Intel 945 chip in the R60e a virtual size larger than 2048 will disable DRI. (If you do not need 3D graphics that is not important.) I am using Ubuntu 7.10 on a 2nd Gen MacBook. ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New -- intel xorg driver disables direct rendering for virtual display larger than 2048 https://bugs.launchpad.net/bugs/164049 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
