Description of problem:
I looked at someones 'fpaste --sysinfo' from f21 (xfce spin probably), and I noticed that part which use 'grep' to find 'drm' info from kernel log, returns nothing

"* DRM Information (failed: "grep drm /var/log/dmesg"):
     N/A"

because '/var/log/dmesg' doesn't exist, tested it on my system f21 (workstaion), with '--printonly', same result, but 'dmesg | grep drm' returns a lot of information. 

For this possible (NOT perfect) workaround is probably 'dmesg | grep drm' instead of 'grep drm /var/log/dmesg' (this is probably not perfect if kernel log is too long)
(Also tried  'journalctl -b -k | grep drm' but that looks like misses a lot of things which 'dmesg' shows)


Another related issues is probably on f21 but only workstation (or those which use gdm), '/var/log/Xorg.0.log' doesn't exist it is now in journal only. (I think most other desktop spins have '/var/log/Xorg.*.log' (possible to see it with 'journalctl -b -u gdm' (or maybe something better to filter xorg stuff only, without gdm)

So 
"* Xorg modules (grep LoadModule /var/log/Xorg.0.log | cut -d \" -f 2 | xargs):"
returns nothing, and this 
"* Xorg errors (failed: "grep '^\[.*(EE)' /var/log/Xorg.0.log"):" too
