sax2: add checkbox to graphics-settings to enable/disable composite
Last modified: 2007-11-22 12:14:43 UTC
Since effects have become common there should be a way to enable/disable composite without having to edit the xorg.conf. Maybe one could combine the checkbox for 3D-accell with composite.
we already had Composite enabled but encountered severe problems with different drivers. If there is a problem with composite the server even didn't start so it doesn't make sense to have a switch in the GUI because you will not get to that point :) - According to this I will not add such a switch in the sax2 GUI - I will enable composite in our configuration if I get the ok from the Xorg maintainer
We'll enable Composite in the driver profiles, if we think it's stable. The same applies to EXA and AIGLX. This is a duplicate. *** This bug has been marked as a duplicate of bug 247374 ***
If I understood correctly composite would then be enabled automatically for certain drivers. How does the user then disable it, if one does not want to use it? The point that it would not make sense to have it in the GUI because the GUI would not start if composite fails it not valid. Just compare the current scenario and what would change if the checkbox was available. Current: User edits xorg.conf to enable composite -> it fails: user edits xorg.conf again. With checkbox: User enables composite in GUI -> it fails: user edits xorg.conf. So there is absolutely no change at all in case composite fails but a huge improvement if it works.

The experienced user still can edit his xorg.conf.
I run a Geforce4 and while compositing works, it is slower than without. Which is why I would want to disable it for this computer. Why would I want to disable 3D if it works? Yet there is a checkbox in sax2.
We don't plan to enable Composite for nv driver.:-) I think most users want to have 3D enabled by default. So the 3D Button (IIRC still disabled by default, not sure though) was more like pointing out, that we're not willing to support this scenario. If "3D" and "3D desktop effects" are possible with the driver (considered as stable) both should be enabled by default IMO. Enabling/disabling "3D desktop effects" should be a user configuration in the desktops (KDE/Gnome) IMO.
