|Summary||0007793: Unable to run KDE over XDMCP due to gnome 3D errors|
|Description||Centos 7 on the server with XDMCP enabled. Workstation running Centos 7 and attempting to start "Xnest :1 -query server" produces a black window and the server reports:|
<code>Oct 28 08:57:42 nx /usr/bin/dbus-launch: gnome-session-is-accelerated: No composite extension.
Oct 28 08:57:42 nx /usr/bin/dbus-launch: gnome-session-check-accelerated: Helper exited with code 256
Oct 28 08:57:42 nx /usr/bin/dbus-launch: ** (process:32693): WARNING **: software acceleration check failed: Child process exited with code 1</code>
The same failure occurs with the workstation booting into X as an xdmcp client. All our workstations are now failing due to this.
I could not find a way to get kdm to run without gnome on the server. I appreciate that the underlying bug is in the upstream gnome software but the fact that kde on centos 7 has a dependency on it is something centos may be able to resolve.
|Steps To Reproduce||Install Centos 7 - choose "KDE Plasma Workspaces" as the software group to install, configure XDMCP. On the client either boot into xdmcp or use Xnest.|
|Additional Information||This also happens with OpenSUSE 13.1 as the workstation OS.|
Other distros have the same problem.
