** Description changed: - Binary package hint: xorg + [Problem] + Running compiz with dual-head enabled on certain graphics cards does not work. Compiz either errors out and refuses to run, or else fails with a black screen. - I'm using a Lenovo S10-2 netbook (Intel GMA950 chipset, 1024x600 - internal resolution). When I connect a VGA display (Samsung SyncMaster - 757NF) and set it to span, both screens go black with only the mouse - cursor visible. + Compiz displays the desktop as a 3D texture. The maximum texture size + is determined by the hardware capabilities of the particular graphics + card. Some older or lower end cards have a limitation of 2048x2048, + which means if you set up a side-by-side arrangement, the sum of the + horizontal resolutions could exceed 2048. + + [Workarounds] + A. If monitors are rectangular, arrange them above/below instead of left/right + + B. Turn off compiz + + + [Original Report] + I'm using a Lenovo S10-2 netbook (Intel GMA950 chipset, 1024x600 internal resolution). When I connect a VGA display (Samsung SyncMaster 757NF) and set it to span, both screens go black with only the mouse cursor visible. The secondary display works fine if I set it to 832x624 or lower (but this is not really an acceptable option with the size of the display, etc) Using Ubuntu lucid with all updates. This bug was present in karmic as well.
