Description Fabian Deutsch 2013-02-07 13:20:52 UTC
Description of problem:
Currently X11 is required to run cogl/clutter applications.
[0] indicates that X11 can be circumvented by using the egl_kms driver, this is interesting because it would reduce the memory and diskspace footprint.
E.g. I see a usecase when Fedora is slimmed down to be appliance like but someone, like me, still wants to offer a nice user experience, thus Mx/Gtk+ apps.

IIUIC this also requires some additional (gallium?) drivers to be enabled in mesa.

I will investigate. There's some known issues with enabling EGL along side GL but I'll review and see the exact cases for this and whether it applies to this option. It would likely only be, at least initially, done on rawhide

Ah right. I wasn't aware of that.

That'd be cool! :)

I suppose that --enable-gallium-egl also needs to be added to mesa
[0] seems to contain all the switches to build the needed files.

Comment 3 Fedora End Of Life 2013-04-03 19:37:53 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

I've enabled the KMS / EGL support in cogl-1.15.10-3.fc20 and clutter-1.15.92-3.fc20 builds now that mutter-wayland is going to use this.

Nice!
