This only started after an update this week caused me to get a "could not start KDEinit" error message after "startx". I fixed that error by updating several libraries that had been automatically installed, but not automatically updated by the update I did wednesday (I typically only update libraries when requested by other applications I'm updating).
The system comes up normally, I just don't get DRI.
What other info can I provide to help troubleshoot?
