Thanks for the feedback, Andreas. That saves me some testing time. It looks like the security bug (https://urldefense.proofpoint.com/v2/url?u=https-3A__access.redhat.com_security_cve_cve-2D2018-2D14665&d=DwIDbA&c=gRgGjJ3BkIsb5y6s49QqsA&r=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A&m=VStRhNQ03emrmYLjFAIDre-xzZT0Ho_w1biFWTQSbtc&s=pGQ8kJ1ceFEdtE90n9wkzNyf0BcBKbllIvhnPdeLWjc&e=) needs physical access to the console to exploit. Fortunately that shouldn't be a problem in our environment, where the users are more interested in hacking neurons. I noticed in the Errata message for the xorg-x11-server update, it says "The SL Team added a fix for upstream bug 1650634". I'm wondering if this bug fix (https://urldefense.proofpoint.com/v2/url?u=https-3A__bugzilla.redhat.com_show-5Fbug.cgi-3Fid-3D1650634&d=DwIDbA&c=gRgGjJ3BkIsb5y6s49QqsA&r=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A&m=VStRhNQ03emrmYLjFAIDre-xzZT0Ho_w1biFWTQSbtc&s=vz7Ui2PF_YcxXFRgPhPceXRL1HuDpy8255vaqI-vmbE&e=) broke things for the Radeon drivers. Seems a more likely cause than the CVE fix for an argument handling issue. That fix was to support the SL 7.6 upgrade on nVidia hardware. I'll have to see if the 7.6 upgrade (now available) makes the problem go away for the radeon 3000. If not, I'll likely downgrade Xorg to 1.19 on our systems till I hear of a fix for this.
