How big is your dual head? default virtual size maybe too small so you have to set it to size that your full desktop should be. see http://wiki.debian.org/XStrikeForce/HowToRandR12 for details > So it seems that at the moment, I can't have my cake (compiz) and eat it > too (on dual monitors). > KMS would auto adjust virtual desktop sizes when you add monitors to system. If you want KMS you could try mainline kernel builds from https://wiki.ubuntu.com/KernelTeam/MainlineBuilds -- [Lucid alpha2] ATI Mobility Radeon 9600 not displaying on LVDS https://bugs.launchpad.net/bugs/522394 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
