Hello.

Bought JA2 Wildfire for Linux, running it on Ubuntu 19.10.
Install works fine. First start of the game works fine too.

However, subsequent starts of the game fail. Means, the screen flashes for a second and jumps back to the console or desktop.

I get this in the log:

DEBUG: calling wine WF6.exe ...
DEBUG: Search for Video Adapters
DEBUG: 1 displays was found
DEBUG: Resolution configured for eDP-1
wine: Unhandled page fault on read access to 0x00000004 at address 0x7f6c9446 (thread 0022), starting debugger...
fixme:win:EnumDisplayDevicesW ((null),0,0x33f588,0x00000000), stub!
X Error of failed request: BadWindow (invalid Window parameter)

Serial number of failed request: 140
Current serial number in output stream: 143

How to fix that error?

Thanks for helping!

"X Error of failed request: BadWindow (invalid Window parameter) "

Reduce resolution.
the game opens with a resolution 800*600
I changed from 1366*768 (16:9) to 1280 * 720 (16:9) and works

Well,

In case somebody else runs into this problem: The start script for Linux is faulty. If you start the game with wine WF6.exe it works. However, the next problem then is that you have to deal with a missing serial number for the game because it complains about that. You would also need to use wine regedit to add the appropriate entries:

[HKEY_CURRENT_USER\Software\ideal-games\ja2 wildfire]
"Registration"=hex:3c,2f,6f,22,a3,a0,50,22,58,8f,60,22,1e,2d,ad,20

Disappointing that GOG sells the game with a faulty start script.
