[Bug 555641] Re: MASTER: max texture size prevents compiz from running
** Description changed:
[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.
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.
Some example max texture limits:
Radeon Xpress 200M: 2048x2048
Radeon X1600/X1900: 4096 x 4096
Radeon HD 2400: 8192 x 8192
Radeon HD 2600/4670/4850/4870: 8192 x 8192
GeForce 7300/7600: 4096 x 4096
Quadro FX 4500: 4096 x 4096
GeForce 8600/880/9400/9600/120/130/285: 8192 x 8192
Quadro FX 4800: 8192 x 8192
+ i945: 2048 x 2048
GMA 950: 2048 x 2048
GMA X3100: 2048 x 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.
