Twinview - No suitable resolutions Thread - CoreBreach

I just installed the demo. It runs fine, including racing.
However, I only get offered one resolution, which is stretched badly over two monitors, and hence is unplayable.
This would be due to me using NVidia TwinView.

In the General forum (https://www.indiedb.com/games/corebreach/forum/thread/feedback) 1ko also has this problem.
A possible solution was offered:

corecode wrote: standard-resolutions:
this really is LibSDL's fault for not reporting all supported resolutions properly - but i guess we need a workaround for it. for the time being you can try editing the config file by hand (~/.config/CoreBreach/.GNUstepDefaults.plist)

But I don't know what to write in the videoresolution string value. I tried 1600x1152 but this had no effect.

My suggestion would be to give us two boxes where we can type arbitrary X and Y values. That way nobody will have severe resolution issues that can't be easily solved. IMO a list of standard resolutions would be an inferior solution, although doing both would perhaps be the best way.

SPECS:
CoreBreach 1.1.5 Demo
Xubuntu 11.10 x64
GeForce 9600 GTS

hey there.

first off, like most linux games, CoreBreach uses SDL for creating a fullscreen window.
so, CoreBreach should work exactly as good/bad as any other SDL based games, if it works worse, its a bug and i'd like to fix it.

so, how do other SDL based games behave on your twin-view system?

>But I don't know what to write in the videoresolution string value. I tried 1600x1152 but this had no effect.

i've never heard of this resolution, so its not weird that it doesn't work. what IS the native resolution of the monitor in question? also, when trying this you really should start CoreBreach from the command line to see its output to see whats actually going on.

anyway, i don't think just putting the correct resolution there will help much (alone), because SDL seems to view both monitors combined like one, so just adjusting the resolution won't help much, we really want to force it to a single monitor.

research suggests that the current SDL version is really weak at multiple monitor support, but there seem to be some environment variables that could force it to run correctly on one display.
try running it with the variable SDL_VIDEO_FULLSCREEN_HEAD set, e.g.:
SDL_VIDEO_FULLSCREEN_HEAD=0 ./CoreBreach.sh
or
SDL_VIDEO_FULLSCREEN_HEAD=1 ./CoreBreach.sh

this should also make different resolutions available in the video preferences, if not maybe editing the config file with the correct resolution for the monitor helps..
other variables to try would be:
SDL_VIDEO_X11_XINERAMA
SDL_VIDEO_X11_XINERAMA_SCREEN
SDL_VIDEO_X11_XRANDR

if nothing helps i guess you can always set the game to windowed mode, force the resolution of your monitor in the config file and move the window so it exactly covers one monitor ;-)

Thanks for that.

SDL_VIDEO_FULLSCREEN_HEAD=0 ./CoreBreach.sh allows me to select 1600x1200 fullscreen, which is good enough. (My left monitor is currently 1600x1200).
I couldn't get the videoresolution value to do anything. 1600x1200 didn't work. (I was after 1600x1152 in windowed mode).

I still think the best solution would be to allow manual editing of the resolution values (perhaps after ticking an advanced button). That should always work in windowed mode. Not sure if SDL would accept it in fullscreen, though.
