Has anyone succeeded in getting the Witcher 2 (Linux version) to work on Mint 18?

I've installed all the dependencies, the options/config dialog launches as expected, but whenever I try to launch the game it crashes... not giving off much info in the logs regarding the problem it's hitting. I'm quite comfortable with Linux but I'm still at a loss as to what I can try to get it running if it doesn't give me any pointers somehow.

I'll try to get the Windows version running in Wine in the meantime, but it feels a bit odd to do that when a Linux version is available...

Any help is appreciated.

Please, post the terminal output and the log file (it should be ~/.local/share/cdprojektred/witcher2/eon.txt).

Here is the content of the log file.

I can't reproduce the terminal output right now, but I remember it was only 4 lines long and only mentioned launching the automatic debug reporting tool. If you think it's very relevant and can help solve the issue I'll paste that as well tomorrow night.

Thanks!

Hello WinterSnowfall,

Could you provide your system report along with the game logs? It might help diagnosing the issue more precisely. You can generate it using the script present in the game installation directory.

If you are not comfortable posting that information here, you can also contact our support at: https://support.gog.com/

Thanks for the support! I've got no issues posting it here, no worries - this is a rig I use exclusively for gaming anyway.

Ok, here goes:
-> full debugger log dump
-> console output
-> system report

Since no significant ideas came to mind, I think I'll leave you in their hands. Good luck! ;-)

First of all, that's a sick machine you have there, congratulations!

Can you describe what exactly happens when the game crashes? Are you able to see intro or main menu, or is it like, no game window at all, just crash right away?

Are there any other files you could provide? Maybe the .dmp file?

Do other games work for you? (This is needed to confirm if your video card drivers are installed properly).

Also - was your game installation completed successfully? Do you have the latest version of the game? Are you sure you downloaded a complete installer? The md5sum of the file is: 3fff5123677a7be2023ecdb6af3b82b6

You can check it by running the following command:

$ md5sum gog_the_witcher_2_assassins_of_kings_enhanced_edition_2.2.0.8.sh

linuxvangog: First of all, that's a sick machine you have there, congratulations!
Hehehe, thanks! :D It's my first dedicated gaming rig and I sort of went full out when I bought it... it should be a good investment though.

linuxvangog: Can you describe what exactly happens when the game crashes? Are you able to see intro or main menu, or is it like, no game window at all, just crash right away?
No intro, no main menu, the screen goes black & fullscreen or windowed for a few seconds depending on how I configure the game resolution before starting it, like it's trying to load but then quits directly to the debugger/error reporter.

linuxvangog: Are there any other files you could provide? Maybe the .dmp file?
Yep, sure. Here's a freshly generated one, since it's created under /tmp.

linuxvangog: Do other games work for you? (This is needed to confirm if your video card drivers are installed properly).
I own quite a few games on GOG that pack Linux builds and I've had no problems whatsoever with them, they just worked (which proves gaming on Linux can be as simple as on other OSes!). For e.g.: SOMA, Divinity: Original Sin, Hollow Knight, Never Alone etc.

I even got The Witcher 3 working on the latest Wine build in staging... managed to get The Witcher 2 working in Wine as well by the way, but it does have some annoying little glitches - like rendering a black screen in cut-scenes if depth of field is enabled. But anyway, that's beside the point :).

Yes, the installation went well, no issues there. I've double checked, it's the latest version. Just checked the md5sum as well and it's a match.

No need to hold my hand, I know my way around these things :). The penguin is an old friend with few secrets by now.

I'd like to thank you again for spending time on this and I hope it helps someone else in the long run, but I've taken heed of GOG's clear message that gaming on Linux is not a priority and it pains me to say that I've bought and I'm going to install Windows 10 on my rig. It's probably the biggest concession I ever felt I had to do in order to get the full palette of games I'm interested in running properly, indirectly because of GOG's decisions as to Linux support as well. And before you ask, yes, most of the games I'm interested in playing have working Linux builds on other distribution channels.

Again, I'd like to emphasize I've not taken this step due to the issues I've been having with The Witcher 2, because it's actually the only problem I had with any of the GOG packed Linux builds - all the others I've tried worked flawlessly, and I've tried quite a few. The issue is that there aren't that many games with Linux builds in general and I don't have the time to spend tinkering in Wine to get Win builds working under Linux any more.

I'm not going to make a fuss about it any longer, it just saddens me things got in this state. In the long run someone in marketing is going to look at the statistics, see one less Linux gamer and decide gaming on Linux is still not worth investing in, though I'd switch back to Linux in a second if it got proper support... *sigh*.

So, the problem's solved, you could say, at least for me.

I am afraid I won't be able to help you any further with this one as I'm not the developer of this game and unable to address the .dmp file properly. I compared your run log with mine and I don't see anything unusual. I couldn't also find anything useful when researching similar bugs reported by users. I recommend contacting CDPR directly about the issue: http://en.cdprojektred.com/contact-support/

Of course, feel free to also contact our support if you have any other, non-technical questions about the product: https://support.gog.com/

Thank you for your honest and direct opinion. As a Linux user myself I understand it very well and I hope you will decide to support Linux gaming in the future.

No problem, thanks again for having a look over it in any case. I'd gladly open a ticked if I could continue investigating the issue, but I plan on rebuilding the rig soon so it's not really worth it any more.

Honest and direct opinion? Is that what you call my whining? :)

Anyway, I'll most likely also get a somewhat gaming-capable netbook soon to replace my aging laptop and I do plan to use Linux exclusively on it. With some light(er) gaming at least I'll also be keeping an eye on the Linux gaming world as well. Valar Penghulis!

I was thinking that you may want to try to run the game using another kernel. It's a shot in the dark, but sometimes it may help with unexplained issues.
I'm not familiar with Mint, but I think you can install another kernel. I use Arch and I have two kernels installed for security reasons: I can choose one of them at boot. According to your system report, you are using kernel v4.10.0-32: you could either try with the latest (v4.12) or an older major revision such as v4.8.

WinterSnowfall: I'll try to get the Windows version running in Wine in the meantime, but it feels a bit odd to do that when a Linux version is available...
Well, consider that the Linux version isn't native because it uses a wrapper known as eON.

That's not a bad idea actually - I haven't tried a different kernel. Thanks for the suggestion. It's too bad I no longer have anything to try it out on...

Oh, I see. Didn't know that, I was under the impression it was a source port... well then, perhaps the wrapper disliked something, who knows.
Huh, you uninstalled Linux entirely? If you were going to install the virus called Windows 10, wouldn't it be better to dual boot? That way you could use Linux for normal things, and games that run well, and Windows when games don't work.

For what it's worth, I've recently upgraded to Linux Mint 18.2 (from Mint 17.1), on kernel 4.8.something. Witcher 2 works flawlessly.

Sounds like you have a strange problem, so maybe a perfect storm of combinations mean it doesn't work?

Pangaea666: Huh, you uninstalled Linux entirely? If you were going to install the virus called Windows 10, wouldn't it be better to dual boot?
After 5 years of dual booting between Win7 and Mint, I've just given up on the concept. It's just too hard to maintain both OSes and switching around between them gives me a headache. Since this is exclusively a gaming rig I'm talking about, I'll just have to drink the poison... I mean, I may not like Windows 10, but now I am able to run The Witcher 3 @1080p on Ultra without breaking a sweat (well, ok, even in Wine it worked flawlessly on High, but now I can really show off :).

I'll install Linux on my new laptop/netbook when I get it. Only Linux.

It may have been a combination of ill factors between hardware and kernel, who knows. If I'd have spend a day or two to wack at it I'm sure I'd be able to get it running eventually. Now I'll slowly die of Windows intoxication... maybe if I quickly launch the games I want to play after I boot it I'll be able to survive somehow.
