I installed Neverwinter Nights on this very machine while running 12.10, following the instructions here. Since upgrading to 13.04, nwn hangs when I run it. This is a strace log file generated by my modified startup script. I have to
kill nwn and
kill -9 nwmain because it never unloads. No window ever opens. If I'm reading the log correctly, it doesn't find some libraries and then segfaults and hangs.
I tried first with my unchanged installation created under 12.10, then reinstalled fresh from the DVD but with no change. I seem to be having exactly the same problem as in the "Neverwinter Nights does not run in 12.10" question on here (not enough rep to link), but that was never resolved either. Googling has yielded no similar reports for 13.04.
Of the libraries I've tried to manually verify the existence of, the only file I couldn't actually find is ld.so. manpages.ubuntu.com doesn't have an entry for it in 13.04, interestingly. Unfortunately I don't know enough about how libraries work under linux to know if this has any bearing on my problem or is maybe just another xorg.conf, which no longer exists in its original form in Ubuntu either.
I'm happy to provide any additional logs or information and I'm no stranger to the terminal.
