Build-19 crashes on startup on Ubuntu / OpenGL detection problem.

[Tuukka Ryyppö]

This happened right after having added the PPA sources, updating the sources and installing widelands with sudo apt install widelands.

The game flashes a presumably 800x600 px window, but refuses to start, with the following error:

Just earlier the same day, build-18, which I had gotten from the default Ubuntu repositories, was running just fine. The OS installation should be new. I just bought the computer yesterday at a city bureau that readies city workers' old work laptops for sale and always installs fresh Ubuntu installations on them. All that I had done

Could you please provide the used graphics card and driver?

I am not familiar with Ubuntu anymore but something like this may work:

lspci -nnk | grep -i VGA -A2

If you have package mesa-utils installed:

glxinfo | grep 'OpenGL version string'

Hello, and welcome to Launchpad :)

>build-18, which I had gotten from the default Ubuntu repositories, was running just fine

Older versions (like build 18) used to have a software renderer as fall-back if opengl didn't work. You may have only used this briefly before upgrading, but do you remember whether build18 was using opengl or not?

Also, could you try running `glxgears`? This is a small sample opengl program so we can see whether the issue is general or limited to Widelands.

please also report output of glxinfo.

For comparison i attache the output of glxinfo from my Laptop, also Intel driven graphics.

On first view this seems suspicious:
> Video memory: 192MB

On my machine this is:
Video memory: 1536MB

Launchpad makes trouble with the attachment, i will upload it later

[Tuukka Ryyppö (dakkus)]

I now downloaded the build-18 package for reference (and data for build-18) and unpacked the deb. Got it from packages.ubuntu.com and it's the package for my Ubuntu version. After copying a font file around, I was able to run build-18 under my home dir. So:

The starting menu views and presumably the whole game works. Build-19 of course still doesn't work, so this is only for reference.

This is the output of build-18 before I quit the game:

glxinfo only reports Mesa. AFAIK this is a software only renderer for OpenGL. It seems likely that SDL ignores this, as it will not provide hardware accelerated graphics (which are now required for b19).

In b18, in the options menu you can enable OpenGL. I bet that it won't start then either.

It seems like you are missing OpenGL drivers for your graphics card, or they are not properly configured. I do not know how to go about this though :/.

[Venatrix (elisabeth)]

What I’m more concerned about is the OpenGL version. It’s said to be:

> OpenGL version string: 1.4 Mesa 11.2.0

I get this on my machine:

> OpenGL version string: 3.0 Mesa 11.2.0

So, if I had to guess I’d say it’s not Mesa which is not working properly but the card itself which is not able to support OpenGL 3.0+. Could that be?

[Hans Joachim Desserud (hjd)]

Came across this issue again since bug 1701966 was just reported.

Since this was initially filed, a newer version of Mesa has become available in Ubuntu 16.04. (https://launchpad.net/ubuntu/+source/mesa) I don't know whether this will affect much in practice, but doesn't hurt to try. Could you check that you have all updates installed and retry Widelands? If still doesn't work (or even if it does), could you attach the updated glxinfo output?

Hi,

  just installed build19 in Xubuntu 18.04.01 and I got the same error:

Installed packages:

* widelands/bionic-updates,now 1:19+repack-4ubuntu0.18.04.1 i386;
* widelands-data/bionic-updates,now 1:19+repack-4ubuntu0.18.04.1 all

This is the output from glxinfo command:

glxinfo | grep Open

And this, from lscpi command:

This is the kernel version:

The program glxgears works fine.

Thanks.

I guess the reason that we can't detect anything is that we'd need something like "OpenGL shading language version string: 1.20", which isn't reported by your graphics driver. 1.20 is our minimum supported version for the shading language.

This is what the output looks for me on a working Intel card on Ubuntu:
