This needs to be re-opened on gnome-desktop3 as on Quantal the error message shown is no longer appropriate as unity-2d is not available. As well as changing the error message is it not the case that on Quantal the underlying problem can be solved by the use of llvmpipe? I keep asking this question but no-one has responded.
The existing message is "Requested size (%d, %d) exceeds 3D hardware limit (%d, %d).\n" "You must either rearrange the displays so that they fit within a (%d, % d) square\n" "or select the Ubuntu 2D session at login.")" -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-desktop3 in Ubuntu. https://bugs.launchpad.net/bugs/824099 Title: Max GL texture size can break multi-head Status in Compiz: New Status in Unity: Won't Fix Status in Unity Distro Priority: Fix Released Status in “compiz” package in Ubuntu: Invalid Status in “gnome-desktop3” package in Ubuntu: Fix Released Status in “unity” package in Ubuntu: Won't Fix Status in “compiz” source package in Oneiric: Won't Fix Status in “gnome-desktop3” source package in Oneiric: Fix Released Status in “unity” source package in Oneiric: Won't Fix Status in “compiz” source package in Precise: Won't Fix Status in “gnome-desktop3” source package in Precise: Fix Released Status in “unity” source package in Precise: Won't Fix Bug description: There's a longstanding issue (see the duplicate bug #555641) with Compiz and multi-monitor setups with any combined dimension larger than the maximum GL texture size. It used to be the case that this would simply crash compiz, but mesa now has code to fallback to software rendering for those cases. Unfortunately, this rendering is unacceptably slow (on the order of 10s of seconds per frame), particularly since the only hardware that will realistically hit this limit is netbook hardware with the associated anaemic CPU. It also appears to be broken in some cases (see bug #830949), although I can't reproduce that myself. The Compiz "Copy to Texture" plugin can break textures up into <= max texture size chunks, allowing hardware rendering to work with these large framebuffers. This is insufficient for Unity, though, which also needs a way to break up its FBOs. For Oneiric we should patch g-s-d's xrandr plugin to disallow setting a multi-monitor configuration with any dimension >= max texture size when Unity is running. Additionally, the display capplet should not allow a resolution to be explicitly set that will break Unity. For P this should be dropped in favour of enabling Compiz's "Copy to Texture" plugin and fixing Unity. String Freeze Exception Request: This patch adds a new failure mode and explanatory error message to gnome-desktop's randr handling. This new message is required to explain to the user why their multi-head setup request has been rejected, and what can be done about it. Original report: THIS IS A MASTER BUG OF FOUR DIFFERENT BUGS: [nVidia] https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/830955 [Intel N10] https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/830949 [Intel Arrandale, Mobile 4 Series] https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/830952 [ATI] https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/830953 Oneiric Alpha 3 installed on this system. Under testing, one test is to plug in an external monitor and ensure that external video functions properly. On this EeePC, it does not. (See photo attached to this bug). Once the external montior is plugged in, both the primary display and the external display are horribly garbled. The only thing that exists on the screen that's remotely readable is the panel at the top. The rest of the desktop area is just a mess.
