I'm posting this for my roommate who is the one that bought this but I do all the tech support for her. She got this because it supports Linux...or does it. While the game has a Linux installer it does not work. Install is fine but launching the game sees a few different random events happen. Going off memory the game will crash with erunloop never exiting. Some times you can kill that and relaunch and get the launcher which will launch, kinda. If you get the launcher you will get one of two outcomes. The game will launch and immediately crash citing connection to X was killed or the game will run up until you load saves or start a new game. Loading saves will hang the game with no recourse but to kill it and new game will just crash. It's like a branching choose your own adventure where all choices end and failure and you still don't get to play the game you paid for.

Every once in a while the X error will also throw in:
‎01/15/2023 | 01:16:13 AM ‎: CrashReporter.x86_64 failed to start due to the following dependancy problems:
Inconsistency detected by ld.so: dl-version.c: 204: _dl_check_map_versions: Assertion `needed != NULL' failed!

Reading up on that since it's not a dependency but rather a c built into an unnamed dependency (and is a "should never happen" scenario) I then tried strace to sus out some more info to no avail. The only thing I haven't done yet is LD_DEBUG but since she was so into the story and games I bailed and grabbed the stupid Win version to run in Wine...again that said reminder Win32 is the only stable ABI.

GOG needs to fix this BS and ensure and TELL the user if there are missing dependencies. Everything online says all you should need is lib32-gnutls lib32-libcurl-compat lib32-libcurl-gnutls lib32-sdl2_image lib32-sdl2 which are all installed.

I drive a 64-bit Gentoo linux desktop and I had to rebuild all of my libraries in both 64 and 32 bit versions to get the game to work. ISTR that I also needed to create a couple of soft links to 32-bit libs that weren't where the game expected them to be. Sorry, but I didn't keep accurate notes of everything I had to do. strace is your friend here.

My problem now, and I think it's the only remaining one, is that I can't get my XBOX 360 controller to be recognized by the game. See my post here for a description of the problem.

Hello
The problem isn't the availability of games. The problem is the complete fragmentation and confusion when it comes to graphics drivers. In the Linux world, there are proprietary and open source drivers for both AMD and Nvidia graphics cards, and those are included right in the kernel.

Probably a bit late but:

I run The Witcher 2 on Lutris. Meaning I installed GOG Galaxy on Lutris(it's a PITA if you want a working overlay. Need to insert dgVoodoo translation from dx9 to 11 and that might give you graphical artifacts and/or errors and what not.), run this on Wine-GE-Proton latest / dxvk latest.

IMO, don't bother with the Linux native version. It runs pretty servicable if not very well on this setup, again DX9 and DX12 games don't give me an Overlay(ony a default desktop mouse cursor) so no screenshots and likely achievement popups but I suspect they will still register. Can someone confirm this?

In any case, check this out: https://lutris.net/games/the-witcher-2-assassins-of-kings-enhanced-edition/

The only thing that bothers me right now, with the inclusion of achievements, is that I can't get the overlay to work (might not be implemented even on win?). So I don't know if it'll register completed achievements.

If you're experiencing issues with The Witcher 2 game on Linux, here are a few troubleshooting steps you can try to address the problem:

Update your system: Ensure that your Linux system is up to date with the latest software updates, including the graphics drivers. Outdated system components or drivers can cause compatibility issues with games.

Verify game files: If you installed The Witcher 2 through a platform like Steam, use the built-in file verification feature to check for any corrupted or missing game files. This process varies depending on the platform, but it typically involves right-clicking on the game in your library, selecting "Properties" or "Manage," and choosing the option to verify files.

Check system requirements: Make sure your Linux system meets the minimum system requirements for The Witcher 2. Check the game's official documentation or the store page where you purchased the game for the required specifications. If your system falls short of the requirements, you may experience performance issues or compatibility problems.

Graphics settings and drivers: Adjust the graphics settings within the game to lower the graphical demands. Try reducing the resolution, disabling anti-aliasing, or lowering other graphics options. Additionally, ensure that you have the latest graphics drivers installed for your specific GPU model.

Community patches or fixes: Search for community patches or fixes specific to The Witcher 2 on Linux. Online forums, game communities, or the official game website may have user-generated fixes or tweaks that address known issues on Linux. These patches may help resolve compatibility problems or performance issues.

Wine or Proton: If you're running The Witcher 2 using compatibility layers such as Wine or Proton, make sure you have the latest version installed. These compatibility layers allow running Windows games on Linux, but they may require specific configurations or adjustments to work correctly with each game.

Contact support: If none of the above steps resolve the issue, consider reaching out to the game's support team or the platform through which you purchased the game. They may have additional troubleshooting steps or specific recommendations for running the game on Linux.

Remember, compatibility issues with games on Linux can vary depending on the specific hardware, software configuration, and game version. It's also helpful to check online forums or communities dedicated to Linux gaming, as others may have encountered and found solutions to similar issues.

Useless info +1

This is a Microsoft forums-tier response.

I'm helping my roommate with a tech issue. She purchased a game that supposedly supports Linux, but we're encountering problems. The Linux installer seems fine, but launching the game triggers various errors. Sometimes it crashes with an 'erunloop never exiting' message. If we manage to get past that, the launcher might start but then fails. Either the game crashes immediately, citing a problem connecting to X, or it crashes when loading saves or starting a new game. Every path we take ends in failure, preventing us from playing the game.

Additionally, we've encountered this error: "01/15/2023 | 01:16:13 AM: CrashReporter.x86_64 failed to start due to dependency problems: Inconsistency detected by ld.so: dl-version.c: 204: _dl_check_map_versions: Assertion `needed != NULL' failed!" This seems to be a rare issue with a built-in C component of a dependency. I tried using strace to gather more information, but it didn't help. I haven't tried LD_DEBUG yet. Frustrated, I resorted to installing the Windows version of the game to run in Wine, as it's more stable.

I think GOG should address these issues and inform users about any missing dependencies. We've installed all the recommended libraries (lib32-gnutls, lib32-libcurl-compat, lib32-libcurl-gnutls, lib32-sdl2_image, lib32-sdl2), yet the problem persists.

It seems like you're experiencing issues with the achievements in the "Blood and Wine" DLC of "The Witcher 3" on GOG (Good Old Games). This situation is reminiscent of the early days of "The Witcher 3," where there were similar problems. You've completed the DLC but haven't received the achievement for arriving in Toussaint, and other achievements are either unlocking randomly or not at all. For example, the achievement for completing the wineries quest and getting a wine named after you hasn't been unlocked yet.

Despite these issues with the achievements,you still consider "The Witcher 3" along with its DLCs as the best game you've ever played. It's clear that your overall experience with the game is positive, even though these technical glitches with the achievements can be frustrating. It might be worth reaching out to GOG's support team to report these issues, as they could be related to bugs that need to be fixed in their system.

Most of those old EOn translated native ports are either broken, unstable or perform like a sack of fresh turd nowadays. I recently rebought this on GoG and tried the Linux version first. I had a save near the end of the game and it worked, but performace was jerky. When I started a new game, it crashed right after the opening cut scenes. Crashed again soon after on the next launch.

So I just sighed and downloaded the Windows installer archives and set it up through Wine with DXVK. (I use a wine-tkg 9.20 based build for my system wine... DXVK 2.4.1 current master). The launcher doesn't work correctly... while you can get into settings, the button to launch the game is defunct, so just run witcher2.exe directly.
