I did a lot se search and it all came down to newer versions of Linux
kernel using kernel mode setting (KMS) enabled for radeon driver.
Parabola uses newer Linux kernel versions too. In newer Linux kernel
versions radeon and KMS work together or graphics do not work as per
Parabola has diabled KMS bun gNewSense and Trisquel do not, I don't
know why. Even the Parabola dual-boot CD has KMS disabled. But story
does not end here. I am using Trisquel currently and I get nice X
environment but when I try to run my own WM, by using startx, it fails
with some error. It runs X only if X is already there (e.g. if some
display manager) i.ei it runs X automtically or not. So I am stuck
using automatic X sessions using lightdm and unable to use StumpWM :(
I am sure X will start failing once gNewSense or Trisouel start using
newer kernels in upcoming versions. Parabola is bleeding edge, so I
came across problem quite fast.
Only gNewSense work flawlessly for everything but its current version
is too much outdated for me. Here is some info:
