It looks like a log for running the installer for BG2, not for the actual game.

By the way, after installing Wine I noticed that there were some errors related to PulseAudio and sound didn't work sometimes (when other process used the sound device). Installing libasound2-plugins:i386 fixed that.

Since it even started (BG2), you should have 32 bit OpenGL already, otherwise it wouldn't even run at all. So I'm puzzled where the .so files of the driver went... Try running more demanding games like Deus Ex or Far Cry. You can even try Witcher 1 (TW1 requires a number of Wine tweaks to run, but PlayOnLinux can probably handle them). If OpenGL is missing, none of them would even start.

Check the error in the console for BG2 (i.e. run it from console with Wine). That can help identify what the crash is about during saving.

About DVDs - regular video DVDs are encrypted with so called Content Scramble System. Proprietary OSes ship DRM components to view them. Naturally Linux doesn't do anything like that. And since CSS DRM is already broken for a long time, there is a library (libdvdcss) which implements this very breaking and which many players on Linux can happily use. The only problem is that distros can't include this library in official repositories because of the insane DMCA lunacy. So that's why they are packaged in other community repos which are just ignoring this whole mess since they are located outside DMCA regulations.

Situation with Blurays is somewhat different (but I don't even have a drive for them, so I don't care). But if you are interested, here is a good overview: https://wiki.archlin...ndex.php/BluRay

You can also attempt to install the driver manually. sgfxi downloads it to: /usr/src/sgfxi-downloads/
Find the driver there (in my case it's: NVIDIA-Linux-x86_64-319.23.run)

Check the integrity of the file:

sh NVIDIA-Linux-x86_64-319.23.run --check
check sums and md5 sums are ok

run it with sudo (using your version, yours should be from previous series of drivers, which were the last for 7xxx cards):

sudo sh NVIDIA-Linux-x86_64-319.23.run

At some point there it should ask you if you want to install 32 bit OpenGL drivers, so say yes.

That GPG error is indicating that the multimedia repo is not official. It's known to Debian community, but it's up to you how to delegate trust. If you want to trust it implicitly, you can install this package from there to avoid warnings: deb-multimedia-keyring. From there you'll be probably interested in libdvdcss2 package, which allows watching video DVDs with various players like vlc and mplayer (it's DRM decryption library).

32 bit OpenGL drivers are needed for Wine to function, so this is important. I wonder if missing 32 bit libs can be something specific to the card that you use. For example Nvidia disabling 32 bit driver for that card for some reason?

In order not to guess, you can ask on Nvidia forum if your specific card has normal 32 bit support on 64 bit Linux (describe your setup). But try running something from Wine for a test anyway.

Will be there big ships sailing too? There are some in the screenshots.
