Looks like it's trying to use the X11 EGL backend, which can't work in the X server. Was 'drm' included in the --with-egl-platforms= parameter to Mesa's configure?

--- Comment #4 from Michel Dänzer michel@daenzer.net --- How are you starting the X server? Does the shell which starts the X server contatin the environment variable EGL_PLATFORM=x11, or does it help if you set EGL_PLATFORM=drm?

Either way, please set the environment variable EGL_LOG_LEVEL=debug for starting the X server and attach its stderr output.

libEGL debug: Native platform type: drm (environment overwrite)

So you set EGL_PLATFORM=drm? Would be interesting to see the debugging output without that as well.

...

libEGL debug: dlopen(/home/atitest/install/lib/egl/egl_gallium.so) libEGL info: use DRM for display 0x1b741d0 libEGL debug: EGL user error 0x3001 (EGL_NOT_INITIALIZED) in eglInitialize(no usable display) libEGL info: use DRM for display 0x1b741d0 libEGL debug: EGL user error 0x3001 (EGL_NOT_INITIALIZED) in eglInitialize(no usable display) libEGL debug: EGL user error 0x3001 (EGL_NOT_INITIALIZED) in eglInitialize (EE) RADEON(0): eglInitialize() failed (EE) RADEON(0): glamor detected, failed to initialize EGL.

That's not the same crash anymore, but 'just' an EGL initialization failure. Does it get further if you set EGL_DRIVER=egl_dri2 as well?

The Debug output with EGL_DRIVER=egl_dri2

Yet another crash... Can you get a backtrace for this one with gdb? You'll need to do that from a remote shell, e.g. via ssh.

Looks like you were hitting this crash again in bug 69961. Was it upgrading Mesa or downgrading glamor which resolved it before?

--- Comment #11 from samit vats hysvats@gmail.com --- Sorry for the delay. I was under the impression that bug is closed. I think downgarding glamor resolved the issue that time but again segmentation fault is observed on startx when building glamor with git master with xv enabled by default.

I think downgarding glamor resolved the issue that time [...]

Does downgrading glamor still help? If yes, can you bisect which glamor change triggered the problem?
