Odd video problem [affects Games, Skype, other, with both nVidia and AMD]...

Okay, since I switched to 13.04, I'm having a really strange issue - it looks like an environment parameter got changed and is now wrong and have no idea where to set it up. This affects both my desktop (running Kubuntu 13.04, and has an AMD Radion HD 6770 using the Closed AMD Catalyst driver), and my old notebook (same thing again, Kubuntu 13.04, but this has a GeForce 9600M GS video card using the closed nVidia drivers). For all my games (and for some applications such as Skype) on my desktop, I have to add LD_LIBRARY_PATH=/usr/lib32/fglrx/ (for 32-bit apps) or LD_LIBRARY_PATH=/usr/lib/fglrx/ (for 64 bit apps) else I either get weird graphics problems or crashes (usually Seg faults) because it's unable to locate the driver. Same thing with the notebook, except I have to specify LD_LIBRARY_PATH=/usr/lib32/nvidia-313-updates (for 32 bit apps) or LD_LIBRARY_PATH=/usr/lib/nvidia-313-updates/ (for 64- bit apps). I de-installed and reinstalled the drivers numerous times, no change. I'm a little frustrated at haveing to edit my K menu to add this to the command line of my applications that suddenly don't work, is there something else I can do to not have to edit the command lines for my menu items

Just tried the open source drivers on both machines - this issue is non-exisitant with those drivers. It's only when using the closed drivers.

Found a fix!!! And what *buntu is failing to do!

This even fixes Skype!!!!!!

Okay, in the direcotry /etc/ld.so.conf.d/ are two symlinked files:

i386-linux-gnu_GL.conf
x86_64-linux-gnu_GL.conf

The fix: open i386-linux-gnu_GL.conf with your favorite editor as root (I use midnight commander 'cause I'm old skool and manage my files like I did in my DOS days - Kate, VI, etc are all fine for this)

Ensure that the path for the 32-bit GL libraries are in there, and if it's not, add it:

So for AMD Catalyst drivers: /usr/lib32/fglrx
So for nVidia (313 series drivers at least): /usr/lib32/nvidia-313-updates

Save the file and then open x86_64-linux-gnu_GL.conf with your favorite editor (as root naturally).

Ensure that the path for the 64-bit GL libraries are in there, and if it's not, add it:

So for AMD Catalyst drivers: /usr/lib/fglrx
So for nVidia (313 series drivers at least): /usr/lib/nvidia-313-updates

Save the file, and then run ldconfig as root. All that done, all the problem solved.

Oh, just a quick note: nVidia users will have to update these file manually everytime the driver series changes (I can't find a way to add the bug to launch pad)...

AMD/ATi users may not, but if those directories ever change...
