Mac Radeon 7000 vs "Screen display mode"

Vincent Weylind · Post by **Vincent Weylind** » Fri Aug 24, 2007 12:00 am

As I read this forum, it seems I have a common problem yet I cannot fix it. When I try to log in, I get the "Unable to find requested screen display mode" message.
- I have searched the forum but there doesn’t seem to be any thread that matches my setup (I think):

Macintosh G4
OS Tiger 10.4.10 (all Apple updates made)
ATI Radeon 7000 PCI (ATI / AMD updates done)

I have tried
- different monitor resolutions and color depth
- different Options (Fullscreen / Window, Graphics quality, Color depth, Texture update, even Frame rate)
- to modify the .cfg file directly
- to both run the Illarion client from my computer and by clicking "Play Game" on the main page.

Any ideas or suggestions would be much appreciated.

Is the color depth of your desktop and the game identical?

And does the ATI driver supports OpenGL?

I have set the monitor color depth to "thousands" and "millions" and then tried the client using 16, 24 and 32 bit, just to have gone through all options.

I have tried setting the monitor to 1024x768 (Illarion window and fullsize), as well as higher monitor resolution (1280x960).

The Radeon 7000 supports OpenGL 1.3. I ran an OpenGL test application that confirms this for the system. Could it be that Illarion requires a later version? It is a 32 mb graphics card by the way.

The current version is 2.1

Is there any driver that supports the version 2.0 or later?

I see, that’s the problem then.

The driver installer supports later OpenGL versions, although the 7000’s hardware cannot go beyond 1.3. The next generation of ATI cards were capable of 1.4, and the ones after that is the 2.0-generation.

When I searched this forum, I couldn’t find any other OpenGL requirements than that it had to be supported. Only version 1.1 was being mentioned as I recall.

Anyway, thank you for the assistance. Illarion seems like a great game and I hope to be able to visit it in the future.

I played with the Illarion Client allready on ancient cards. So that can't be the real problem.

There should be a "error.log" in the folder you marked as client folder.
The content of this file maybe helps.

The error log only contains this text (over and over again):

VM: 1.5.0_07
OS: Mac OS X 10.4.10
Fatal error: Unable to find requested screen display mode.
Terminating client!

I added debugLevel=1 to the .cfg file, thinking it might add more details?

Use debugLevel=8

And try it.

I changed the line to:
debugLevel=8

When I started the Illarion client today, it downloaded again (an update?). As I try to log in, it quits with the same error message as before, but now the error log does not get updated at all. Should I try with some other debug number?

EDIT: I have now tried all numbers from 1-9 as debugLevel. Some generate the earlier error message, some leave the error log unchanged.

Try a update to a newer Version of Java. Maybe this helps.

As far as I can tell, I already have the latest Java update release from Apple (1.5.0_07, from february this year).

Thanks for not giving up so easily on my case though.
