I don't remember why I updated; possibly the problem I was having is 
gone anyway.
I'll try to go back to default version.

I've been using an HD4200 for several years: it's listed as "Works" on 
the AMD-GPU-Matrix page and I've been very happy with it.

AFAICT, HD4250 should be the same chip (RS880), just with a slightly 
higher clock and some dedicated RAM, so I thought it would work as well 
(and with the same configuration).
I understand the devil is in the details, though.

Sorry, I do not understand that question.
I'm using xf86-video-ati-18.1.0,1: is this the info you wanted?
I think I posted every info on my system; if it's something that's not 
there, where do I find it?

I'll try this too.
