Broken X on hybrid graphics due to missing GL_OES_EGL_image OpenGL extension
Last modified: 2015-09-28 14:52:38 EDT
Description of problem:
Upgrade to the latest mesa version broke my X on a hybrid graphics setup (Intel+Radeon).
Starting the gdm service leaves me with a blank screen and a frozen system.
(Certainly because systemd is trying to bring up the failing gdm over and over again).
The relevant information from my X-logs is
No provider of glEGLImageTargetTexture2DOES found. Requires one of:
GL extension "GL_OES_EGL_image"
A plain startx with a twm-~/.xinitrc shows the very same behaviour (regarding the logs, the system is not frozen).
Renaming /usr/lib64/xorg/modules/libglamoregl.so makes by twm-~/.xinitrc-startx working again.
Version-Release number of selected component (if applicable):
mesa packages are at version devel.5.47e18a5 right now.
This upstream patch https://patchwork.freedesktop.org/patch/59719/ looks like it could fix that issue.
Please see possibly related/identical bug https://bugzilla.redhat.com/show_bug.cgi?id=1265625
If I were able to, I would upgrade this issue's severity to urgent.
Just checked that a 'fedpkg local' build with the previously mentioned patch from
manually added to the 'mesa.spec' fixes the issue.
It does: gdm and gnome-shell are up and running again.

hm, looks like it's already applied to latest build in f23 and f24.
Verified. That patch has also been applied in the upstream sources ('mesa-9932142.tar.xz') introduced by you in fedpkg commit 3851ec79.
-> No need for action here anymore.
Okay. Thanks for clarification.
