Running 32-bit 3D apps on 64-bit Debian NVIDIA systems
Because Intel on-board video isn't quite good enough at 3D and my somewhat old laptop with built-in NVIDIA chip wasn't doing all that well at X-Plane either, I bought an NVIDIA GT240 card. Mostly because it seemed to be a good performer without doubling the power consumption of my PC. Stuff wasn't working all that well though and I got pretty frustrated:
was all X-Plane could tell me. Google Earth also didn't work and seemed more like Google Black hole to me. Both are 32-bit apps. A 64-bit binary of Flightgear did work. Sigh.
After some poking I noticed the nvidia-glx package replaces /usr/lib{64,}/libGL* with its own versions, but didn't touch /usr/lib32. A-ha!
The fix: Get a 32-bit version of nvidia-glx, extract it somewhere (dpkg -X) and copy all the files in its usr/lib to /usr/lib32, overwriting the libGL symlink that is currently there.
Or, hmm, as I just found out: apt-get install nvidia-glx-ia32. I'm glad someone thought of it already.
Now X-Plane works perfectly (with maybe even ten times the frame rate I had with Intel on-board) and Google Earth can show me my house again.
Just blogging this since so far a Google search for any part of the error above didn't give useful results.
Now, I just have to find out if I can get a TV signal out of this thing somehow, since my TV was made long before HDMI was invented. :-/
