Hi folks,

I'm presently updating the WineHQ Wiki pages for BF2 & BF2142. I am trying to work out if there is way to fake a 800x600 monitor mode which BF2/BF2142 requires when starting up (without using a Wine Virtual Desktop).

For example at present my laptop has an AMD Radeon HD4650M GPU. I have a built-in TFT panel @1366x768 and an external monitor @1600x1200. Like so...
Code:
xrandr
Screen 0: minimum 320 x 200, current 2966 x 1200, maximum 8192 x 8192
VGA-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1366x768+0+432 (normal left inverted right x axis y axis) 0mm x 0mm
   1366x768       60.0*+
   1280x720       59.9 
   1152x768       59.8 
   1024x768       59.9 
   800x600        59.9 
   848x480        59.7 
   720x480        59.7 
   640x480        59.4 
HDMI-0 connected 1600x1200+1366+0 (normal left inverted right x axis y axis) 408mm x 306mm
   1600x1200      60.0*+
   1400x1050      59.9 
   1600x900       60.0 
   1280x1024      75.0     60.0 
   1440x900       84.8     75.0     59.9 
   1280x960       60.0 
   1366x768       60.0 
   1360x768       60.0 
   1280x800       84.9     74.9     59.9 
   1152x864       75.0 
   1280x768       84.8     74.9     60.0 
   1024x768       85.0     75.1     70.1     60.0 
   1024x576       60.0 
   800x600        85.1     72.2     75.0     60.3     56.2 
   848x480        60.0 
   640x480        85.0     75.0     72.8     60.0     59.9 
   720x400        85.0 
   640x400        85.1 
   640x350        85.1 


Wine is a bit dumb in multimonitor.

When running the game on the external display the game will start fine (internal display disabled). When I start on the built-in laptop monitor the game does not start (external display disabled). The debug trace states that the game requires a 800x600@85 xrandr mode.

Note I am disabling the displays in the KDE System Settings. The output of xrandr appears to be correct after I disable a display (the modes for the disabled display do not show up).

Currently I am not using a xorg.conf for my laptops video card as I am using radeon display driver. So my question is can one "fake" a display mode of 800x600 (@ a specified refresh rate) in xorg.conf or using xrandr that actually map to a supported mode (e.g. 1024x768@60Hz)? How would one do this?

Thanks
Bob

Code:
xrandr -s 800x600

will change your display to 800x600.

I've adjusted the inaccurate forum thread title. The original and updated BF2 (& BF2142) code is a bit broken and tries to modeset to 800x600 @85Hz. Many monitors don't support this.

The problem isn't how to set a monitor mode. The problem is that Wine tries to set the display mode to 800x600 @85Hz and fails if this mode is unavailable. My thought was can I fake a 60Hz 800x600 resolution mode (which 800x600 @85Hz maps to). But my feeble attempts haven't got very far... :roll:

Thanks
Bob

You must look if it is possible to configure/force wine to use 800x600@60 instead of 85. I have no clue here.

heh I played BF2 to death :) only recently stopped playing. It tries to do 800x600 @60HZ to initially start up, after that you can use any resolution in game, so make sure you have the option to support 800x600@60HZ either by using modeline in xorg.conf or whatever. I've never played it on wine though so good luck.
