Gzdoom blank screen when booted

I've had this for a little while now. When i boot gzdoom i get the typical "unsupported" display screen with a few moments of it being blank. This seemed to happen when i deleted my .ini file.

Is something wrong with my drivers? I have a Nvidia GT 240

Does it create a new ini? Does ZDoom work?

If so, use ZDoom to set the video mode to windowed and try again.

Yes a new ini file appears upon starting. Software renderer seems to boot just fine when alternating windowed mode as well.

I just did a fresh driver install and the problem still persists. The opengl renderer simply refuses to show up.

By any chance, do you have triple buffering switched on?

GZdoom doesn't work (for me anyway) when this is switched on.

Interestingly, it works for me with triple buffering, though it messes with the transitions (wipe, fade, &c.).

Must be a case-by-case then. It completely dies on my laptop.

No, settings are the exact same as yours however.

I got the opengl renderer to show up, but only in windowed mode. It goes blank and flashes black and grey upon switching to fullscreen.

Well i think i've finally got the solution to this problem. It seems my screen resolution was far too small when in fullscreen (something along the lines of vanilla doom's resolution) and it would not let me view it. I set my res to 1280x720 and that seemed to fix my problem. I'm still not sure where the core issue lies.

Just figured out the source of the problem. It's caused from Jodwin's C#4rp Doom launcher. Upon using gzdoom with it (and possibly a pwad) It causes the - and = screen adjustment keys to become unusable. THEN upon deleting the ini file after restarting the screen becomes blank. The method i posted above fixes this problem. I'm not sure if Gzdoom is at fault here or the launcher, but i will bring it to Jodwin's attention as well just to reassure.

Now that's weird. Why would it hijack the -= keys?

It doesn't. -= keys work just fine for me, and in fact the launcher goes into a frozen state whenever the game starts (this is done to ensure proper cleaning of temporarily extracted zips after game ends):

Code: Select all

(.net 2.0)

		private void RunThePort(string portPath, string commandLine)
		{
			this.Enabled = false;
			Process p = new Process();
			p.StartInfo.WorkingDirectory = Path.GetDirectoryName(portPath);
			p.StartInfo.FileName = portPath;
			p.StartInfo.Arguments = commandLine;
			p.Start();
			p.WaitForExit();
			this.Enabled = true;
		}

That's very strange. I'm assuming this a minority case im dealing with then.
