Filed from caserun (https://tcms.engineering.redhat.com/run/274895/#caserun_11913516) Version-Release number of selected component (if applicable): RHEL-6.8-20160323.0 Steps to Reproduce: 1. Ensure the 'nomodeset' kernel parameters are not set in your bootloader configuration. 2. Ensure the file /etc/X11/xorg.conf does not exist, or is a valid file that uses the valid driver. 3. Shut your system down entirely, then start it up again, in console mode. When the boot prompt appears, hit a key to allow you to change the boot options. Hit the 'e' key on the default entry, select the kernel options line, hit 'e' again, and add simply a space and the number '3' to the end of the line. Then boot with that change. 1. The system will boot to the console. Log in as a normal user. 2. Start X: startx. Actual results: X does not start unless you have mesa-libEGL installed. mesa-libEGL is not installed by default on -Client and -Workstation variants. [ 20.825] ABI class: X.Org ANSI C Emulation, version 0.4 [ 20.825] (II) glamor: OpenGL accelerated X.org driver based. (EOF) Expected results: X should work properly. [ 21.268] ABI class: X.Org ANSI C Emulation, version 0.4 [ 21.268] (II) glamor: OpenGL accelerated X.org driver based. [ 21.417] (II) glamor: EGL version 1.4 (DRI2): [ 21.426] (II) RADEON(0): glamor detected, initialising EGL layer. (...) Perhaps xorg-x11-drv-ati should depend on mesa-libEGL?
This is really an xserver bug. We should require libEGL from whatever provides the glamor accel module, since we can't really do that from epoxy.
