I am using slackware10, fvwm 2.5.12
By default my machine can only use 75 Hz under 1152x864, in order to use 85Hz I added such a line in xorg.conf:
Identifier "My Monitor"
HorizSync 30.0 - 85.0
VertRefresh 50.0 - 160.0
Modeline "1152x864_85.00" 119.65 1152 1224 1352 1552 864 865 868 907 -HSync +Vsync
It works well inside kde and gnome. Now I have compiled fvwm 2.5.12 and found that inside fvwm by default I am using 1152x864@75.00, I change it to 1152x864@85.00 by using the tool gnome-display-properties, and it works.

The problem is each time after restart fvwm, the setting will be changed back to 1152x864@75.00!!why cannot fvwn remember the setting before?? I do not want to set screen resolution every time.

Thanks

no one can help?
