sddm on slackware64 14.2 radeon video chipset problem solved
 

Morning all!
I've had trouble with the sddm greeter bailing after I completed an upgrade from 14.1 to 14.2. At some point, I'd installed Alien Bob's build of sddm - and promptly forgotten about it. It was somewhat confusing when I couldn't find sddm in the slackware64-14.2 distro.

After the upgrade, I could run startx but could *not* successfully execute sddm. After a couple of hours of trying to build a new version of sddm I resorted to just running with Alien Bob's original build script and the 20140508git source. (The newer release of sddm would require several additional dependencies to be built - I'll do it one day but not at present.)

The upgrade also broke bibtex and biber which I use extensively. I replaced the packaged version of biblatex with the latest from CTAN, and V5.2 of biber. (A few perl modules and LaTeX packages were also required). All work as required.

Cheers, Spiro
