Installed with apt.
here's my terminal output...
I have NVIDIA video drivers installed too.

The log say there is an problem with your gpu driver.

[LinuxDonald]

Gpu driver problem.

[z0rti]

What GPU drivers are supported?
I'm using official nvidia-driver-450 package for ubuntu 20.04

$ glxinfo|grep version
GLX version: 1.4
OpenGL core profile version string: 4.6.0 NVIDIA 450.80.02
OpenGL core profile shading language version string: 4.60 NVIDIA
OpenGL version string: 4.6.0 NVIDIA 450.80.02
OpenGL shading language version string: 4.60 NVIDIA
OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 450.80.02
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20

(other games do work)

[LinuxDonald]

Than I don't know what's wrong. There is no active engine dev available.

[vidje]

So any fix for nvidia drivers 460.39?

[LinuxDonald]

Could you rebuild Fife with lastest changes and lastest changes of UH please?

[LinuxDonald]

@jmdejong have you maybe an idea whats broken? I have tested it now to same error.

[LinuxDonald]

@jakoch could you maybe take an look too please?

[jmdejong]

@LinuxDonald what did you do to get the same error? Just starting and playing UH does not give an error for me, but I don't have nvidia graphics.

Is this still specific for ubuntu 18.04 or does it affect other distros as well?

Any idea how to solve it?

[debagos]

Same problem on KDE Neon with proprietary Nvidia driver.

[LinuxDonald]

I think fife engine is broken...

[LinuxDonald]

Could you guys retest it with fifechan 0.1.5 and fife lastest git version and lastest unknown-horizons git version please

[hisoka999]

fifechan won't help, its a bug in the fifengine.

the root problem is the usage of "SDL_GetWindowSurface". this function should not be used with active "3d accelleration".

so if i'm right that would mean that the old code would need some fixing.

[LinuxDonald]

For me it starts under manjaro with nvidia without any problems again.

[coldtobi]

(For documentation: This might be in fife, fifengine/fifengine#1079)

[coldtobi]

German Debian Forums had thread about it [1], and there is a
Workaround documented:

The workaround is to run the application in a Xephyr environment
(package xserver-xephyr), which seems to be without hardware acceleration.

Example for how to use the workaround:

  Xephyr :99 -resizeable -screen 1400x1050 &
  DISPLAY=:99 unknown-horizons

[1] https://debianforum.de/forum/viewtopic.php?t=183160#p1292067

[jakoch]

Hmmm... No hardware accelerated renderers available. Ok, that means the initalization fails on fifengine side.

---

This might be caused by a wrong usage of SDL_ functions, specifically SDL_GetWindowSurface in Fifengine's RenderBackendOpenGL. Referencing: https://github.com/libsdl-org/SDL/blob/main/include/SDL_video.h#L1287

I think it would be better to make the current window the opengl context and then start swapping, before glew_init.
So just SDL_GL_MakeCurrent(handle, context) followed by SDL_GL_SetSwapInterval(1).
The upstream (fifengine) needs a bugfix.

[LinuxDonald]

@jakoch have you maybe the time to create an fix for it please?

[jakoch]

I haven't worked on fife for years. So i need to (re)setup my dev env with repo(s) and stuff first, before i could tackle this.

[armandorub]

I cannot start the game: Select tutorial, then shows me a sailboat on the screen and in a fraction of a second disappears and the program close!
I am in Ubuntu 22.04.1 LTS and i have dual graphic cards: Intel and Nvidia, this last one is GTX 1650.

[coldtobi]

This seems to be a differnt issue, as the one I described above does not even open up a window.
Can you start from a console and see if there is some output hinting towards the problem?

[armandorub]

Here it is:

same here:

[coldtobi]

@armandorub Oh, that looks familiar: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1014084, or on this repo #2956.

[armandorub]

So, I understand this is an open bug and I just need to wait until is solved.
Thank you for your attention.

[coldtobi]

Well, it is fixed here and in Debian unstable;
I'm not affiliated with Canonical/Ubuntu nor this project, (I was just updating the Debian package a few weeks ago.), so you'd need to address that issue with Canonical. However, Ubuntu 18.04 is "end of life", if I am not wrong, so it is unlikely that there will be a fix in this version of Ubuntu. You should consider updating to an supported version...

[coldtobi]

@jrgryph are sure this is fixed?

[armandorub]

So where is possible to download de fixed game?

[jrgryph]

woops

[coldtobi]

So where is possible to download de fixed game?

There are a few options:

• you can try the flatpak version: https://flathub.org/apps/details/org.unknown_horizons.UnknownHorizons
  (this version is too old to have the fix, however, as flatpaks bundle all dependencies this might actually working for you. I did not verify if it does.
• you can try to recompile the Debian package yourself.
  I recently write some instructions how to do that for another package, you can try this instruction I originally wrote
  for another package:

You can rebuild the package for Ubuntu in the Debian way:

Get the .dsc-file, for the version you want by browsing the source package page On that site, towards the bottom, there is a link pointing to the .dsc-file, for example for the latest version, at the time of me writing this, it is pointing to unknown-horizons_2019.1-5.dsc Copy that link.
In a terminal, best in an empty directory (for easier cleanup), you then can build the package:

NOTE: You will need to have "Backports" for Ubuntu 18.04 enable. Otherwise it won't find a recent enough version of "debhelper" and the build will fail. It might be that you need to install "debhelper" from backports (as the package needs version 13 or later) manually.

Disclaimer: I did not try to rebuild the package on Ubuntu. The below instructions might or might not work for you.

# install debian tools for building packages
sudo apt install build-essentials devscripts equivs
# get the debian sources and unpack them
dget -ux <the link you have copied above>
# enter the source directory
cd unknown-horizons-*
# generate a pseudo package to install the build dependencies and install it.
sudo mk-build-deps -i -r
# build the debian package
dpkg-buildpackge -uc -b
# install the created packages 
sudo debi 
# optional: cleanup
sudo apt remove  unknown-horizons-build-deps 
sudo apt-mark auto build-essentials devscripts equivs 

Downside if of course that you won't get updates automatically , but you can subscribe to https://tracker.debian.org/pkg/unknown-horizons to get notifications if something (like new uploads) happens to the Debian package :)

[armandorub]

Thank you very much! I am keeping your recommendations and I intend to follow them carefully.
