Hi,
The thing is that the problem is solved, at least in my computer.
I installed the proprietary drivers as a sudo-user.
And there should be edited file etc/pango/i486-slackware-linux/pango.modules by hand, which was empty. Only needed to copy the entries from / pango/x86_64-slackware-linux/pango.modules, and change the path to / usr / lib / pango.
Currently I am satisfied with this solution, it works.
It's a Salix64-14.1. And Multilib installed from Alien Bob.

Adobe-Reader loads much faster then previous on 14.0. It's improvement.
regards
