Was 'drm' included in the --with-egl-platforms= parameter to Mesa's configure? yes, mesa is configured with "--with-egl-platforms=x11,drm" 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. The Debug output is : (II) [KMS] Kernel modesetting enabled. libEGL debug: Native platform type: drm (environment overwrite) libEGL debug: ignore EGL_DRIVERS_PATH for setuid/setgid binaries libEGL debug: EGL search path is /home/atitest/install/lib/egl libEGL debug: added /home/atitest/install/lib/egl/egl_gallium.so to module array libEGL debug: added egl_dri2 to module array libEGL debug: added egl_glx to module array 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?

Server aborting (In reply to comment #7) > 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. I think it is a regression issue. The issue is resolved with upgrading mesa to latest 9.3.0-devel(git-59157d1) and with glamor-0.5.0 (In reply to comment #9) > The issue is resolved with upgrading mesa to latest 9.3.0-devel(git-59157d1) > and with glamor-0.5.0 Looks like you were hitting this crash again in bug 69961. Was it upgrading Mesa or downgrading glamor which resolved it before? 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.
Xserver version is 1.12.99.905 and this is the backtrace:
