I feel like an utter beginner here, but how do I run the script?
I'm running Nobara linux and telling it to "execute" the file does nothing. Do I need to run it through the console somehow? And if so, how do I do that?

And is this still the best way to get DA:O running? (the preferred wine-script in Lutris asks for the hotfix file, which can no longer be downloaded from GoG as far as I can tell)

Edit:
Okay, I found how to run the script in Konsole, and used the -planb command since the install files from GoG have changed names considerably. The installer claims to have finished successfully, but the script in Konsole say:
Wine cannot find the ncurses library (libncurses.so.5).

As far as I can tell in my package manager, ncurses is installed. There are a number of packages related to it that aren't, but I can't for the life of me figure out which it is that I might need...

Running the game started just fine, with sound and graphics working. However, issued appeared quickly.
* Camera mouse control is way too fast, and seems to get stuck on a single horizontal direction no matter which way I move the mouse, until I move the camera vertically as well.
* Tabbing out to desktop and back caused all controls to stop functioning entirely. I could still mouseover UI elements, but nothing responded to any inputs.
* There seems to be no DLC installed, and tabbing out to desktop and back made all the controls stop functioning.

Edit 2:
Exiting and restarting the game seems to have sorted the control issues at least...

Edit 3:
The game claims it has no internet access (I clicked the button to log in to my Bioware account, even thoug the service is long since dead). Can that have something to do with the dlc not showing up?

Never mind the above. I got it to work in Lutris. I think I was just trying to use an outdated script, or the script for the non-Ultimate edition somehow.

You can safely use the Lutris "auto" installer, it also installs all necessary components, and you don't need to answer any questions. The only thing I needed to do was disabling the DXVK and VKD3D graphics in the Lutris runner options.

No luck here with that. Can't get it to work.
Script above unfortunately also is outdated and expects old files that no longer exist on GOG.
