I just spent the last hour messing around with the graphics modes of this game to make it work properly on my laptop and though I'd share what I did to make it work properly.

First, I'm running Mint 17 on an old Dell Inspiron 1501 which is using an ATI express integrated graphics adapter. Getting Mint to run was a little tricky, the graphics don't work 'out of the box' - and changing any modes causes lines to display which renders the laptop inoperable.

That being said, I had to force the game to either run in a windowed mode or fullscreen at my currently only supported resolution of 1280x800.

GR uses the AGS engine, from what I've read GR only supports limited graphics modes to include:

320x200, 640x400, 960x600 and 1280x800

You can change the graphics modes via the acsetup.cfg file in the game directory (default is /opt/GOG GAMES/[gamename]

The game's original resolution is 320x200, so it supports scaling at that scale.

The line in the cfg file titled 'gfxfilter' can be adjusted as shown:

gfxfilter=StdScale2 -> 640x400
gfxfilter=StdScale3 -> 960x600
gfxfilter=StdScale4 -> 1280x800

In my case, I set the line to gfxfilter=StdScale4 -> 1280x800 in order for the game to run properly on my laptop.

I did some testing in windowed mode (setting it to a value of 1) so my laptop didn't 'line out' as I tried each scale setting.

So that is how I got the game to work on my laptop, hopefully this information will help others if they run into similar issues.

Yes! I am so happy! I have a 16:10 ratio screen (1920x1200) and I have set gfxfilter=StdScale4 which is also 16:10! It works perfectly!!!!
