Does anyone tried to setup the game on Linux ?

I tried on Ubuntu 10.04 and install worked fine through Wine AND PlayOnLinux (tried both) BUT when I tried to launch the game I've got only sounds and no image (black screen).

I've got an Ati HD 3870 with the proprietary driver activated.
Does anyone has an idea of why it isn't working ?
(In General I have troubles making games working on Ubuntu :()

I also have encountered this issue. The quickest way to get going is to launch the wine configuration tool, then click on the 'Graphics' tab, then select the 'Emulate a virtual desktop' option and then change the desktop size to 640 X 480. Then run the game.

If that works for you, then report back here and I will guide you on how to make a icon so only Caesar 3 runs in a Window.

Just for others who may be experiencing this issue. If you create a file named "Caesar 3.desktop" with the below, you should now be able to launch the game (Do not forget to update the bold section with your user name):

[Desktop Entry]
Name=Caesar 3
Exec=env WINEPREFIX="/home/YOUR USER NAME/.wine" wine explorer /desktop=Caesar3,1024x768 C:\\\\Program\\ Files\\\\GOG.com\\\\Caesar\\ 3\\\\C3.exe
Type=Application
StartupNotify=true
Path=/home/YOUR USER NAME/.wine/dosdevices/c:/Program Files/GOG.com/Caesar 3/
Icon=/home/YOUR USER NAME/.local/share/icons/7f3c_gfw_high.png

I had the same problem and this is how I solved it:
1. Run winecfg (for my Caesar3 WINEPREFIX) and set the following:
Applications -> Windows Version: Windows 98
Graphics -> Emulate a Virtual Desktop: 1024x768
Graphics -> Vertex Shader Support: None
Graphics -> Allow Pixel Shader: True (checked)

The rest is the default config.
I have 64bit Fedora with Wine 1.3.9

Thx for replying, I'll try it as soon as I've time to do it !

The problem is the game doesn't work when the resolution is not 1024x768.

Fix: Set your resolution to 1024x768 before running the game. I am sure the virtual desktop also works, but this allows you to run it in full screen.

If you are running the game for the first time, I think it may start in 800x600. Press F6 to correct it.
