Description Forgotten User --EoyBps8f 2007-11-21 16:33:39 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.

Comment 1 Marcus Schaefer 2007-11-22 10:56:19 UTC

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.

Comment 3 Forgotten User --EoyBps8f 2007-11-22 11:15:47 UTC

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.

Yes. nvidia and intel are candidates for this. The only ones.

Why don't you want to have it enabled, if the driver is running stable with
it? The experienced user still can edit his xorg.conf.

Comment 5 Forgotten User --EoyBps8f 2007-11-22 11:56:42 UTC

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.

Comment 6 Stefan Dirsch 2007-11-22 12:14:43 UTC

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.
