Hi,

On Linux the save folder & files is on your home directory /.QuestofDungeons/ the folder is probably hidden because of the .before. Inside there's a config.ini file which can take several settings.

But as for the black screen, I tested on Ubuntu, it's usually my goto Linux OS because Steam stats also suggests it's the most common one. Might it be some drivers thing? On windows for example, even though it's a 2D game, any time someone shows me a black screen or some sort of corrupted rendering situation it's been most of the times drivers. If on a dual screen setup, does it help just having one connected? It's also possible the screen has a particular resolution that messes up things, or even High DPI, which is why sometimes window mode might work. The window handling is done by SDL2, which last time I updated the game I also updated to latest SDL2 version.

Hello and thanks for replying

When I launch the game, the hidden folder is indeed created, but no config file is created

The screen always goes dark with sounds still playing and I can hear the confirmation sound if I keep hitting enter

I'm also on Ubuntu 20.04 (I believe it's the normal one, not the LTS), and I only have one screen (laptop setup)

And the native screen resolution is 1366x768

Also, I tried the game again in a virtual machine also running Ubuntu 20.04, but the results were the same. In the virtual machine, I also tried updating sdl2 through the command given in the wiki (sudo apt-get install libsdl2-2.0), but the log said I was already in the most recent version

Btw, the game runs fine on Android and I haven't tested in Windows 10. Would it be possible to find and use such a config.ini file from one of these 2 versions in the Linux version to see if anything changes?

Hi, yes the same config file can be used. But here's a template you can use.

Save it under My games/QuestofDungeons as config.ini

You can change fullscreen and resolution there, among a couple other things.

EDIT: I messed something up. I thought 1 was false for fullscreen. But then I did a quick search after posting the reply since I was not sure, and turns out it was the opposite. Now with fullscreen=0, the game opens normally on my virtual machine. I'll also try with Win10 now

EDIT #2: Graphics still broken on the Win10 virtual machine after patching the fullscreen parameter. But at least I got it working on Linux and Android. Thank you very much for your help.

I tested the template config file in the virtual machine, but changing width to 800 and height to 600.

The game automatically closed, the native screen resolution of the virtual box got messed up and the text below is the log from the terminal:

ubuntu@ubunu2004:~/Downloads/QuestofDungeons_linux_2.0.4/Quest of Dungeons$ ./QuestofDungeons

X Error of failed request: BadValue (integer parameter out of range for operation)

Current serial number in output stream: 232

AL lib: ReleaseALC: 1 device not closed

I also tried the game in a Windows 10 virtual machine (both with and without the config.ini file), and the graphics were pretty broken. But at least in Windows I could alt-tab out of it

While on Linux I think OpenGL2 supports well on a Virtual Machine, I think a Windows 10 VM not so much, or at least I always had some issues on my systems, I have to use an actual installation, it seems that for the most part the Virtual machines focus on DirectX for Windows and OpenGL for Linux, and this game was made in linux.

The first ever version of QoD was OpenGL 1 which *should* work on windows Virtual machines but I had to upgrade to GL 2 after a couple years and that broke virtual machine. Try using that other version if you wanna give it a try at least, but warning it's really an old QoD version.
