Thanks, Simon.

It actually appears that the Qt dependency is an Ubuntu thing. I found 
an installation guide at AMD and the only graphics requirements are 
Xorg, XFree86-Mesa-libGL, XFree86-libs and fontconfig. Although this 
guided references Xorg-7.6, it looks like it's a bit dated in its 
referral to the XFree86 stuff. I don't know if anything is still name 
that--I'm working through the installation of Xorg now--but I suspect 
that the libraries are part of a standard BLFS install. I did see a *GL 
get installed last night when I was working.

As far as Qt-4 vs Qt-5 go, it was going to be a guess in spite of your 
remarks. I installed the proprietary driver for my chip when I first put 
Ubuntu on. That was at the beginning of Oct. At that time, it was 
"Catalyst*10.1beta2. Last night it was Catalyst*11.3beta9.4. AMD is 
doing a lot of work on it.

I'm belaboring this point in case any other LFS'ers get this chip. I'm 
really careful when it comes to recent AMD-Radeon graphics. Not knowing 
the incompatibility between Xorg and the recent chips, I burned up three 
laptops. Apparently, one of the lacks in those drivers is temperature 
sensing or fan management. So, I decided that until I could verify 
beyond a shadow of a doubt that an Xorg driver supported my chip, I was 
going to use the proprietary driver.

When I found out that the linux version of that driver was in "beta" 
development, I understood why Xorg was behind.
