[K12OSN] "Can't display this video mode"

[Carl Keil]

Hi again folks,

Every once in a while, when popping open different full screen games 
(the user can't be specific, but one is Wesnoth) she gets a message that 
says "Can't display this video mode" on a white screen.  She has to 
reboot the terminal to resume.  I'm assuming this has something to do 
with the flat panel screen she's using.  It's the only terminal that 
does this and the only one with a dell LCD 17".  Here are the lines for 
that client from lts.conf.

#Amer TC500
[00:40:63:c9:54:49]   X_MODE_0 = 1280x1024
   X_HORZSYNC = "60-70"
   X_MOUSE_PROTOCOL = "IMPS/2"
   X_DEVICE_OPTION_01      = SWCursor
#   X_COLOR_DEPTH   =       24
   SMODULE_01      = soundcore
   SMODULE_01      = soundcore
   SMODULE_02      = es1370
#   SMODULE_02     = ac97_codec
#   SMODULE_03     = via82cxxx_audio
#   USE_NFS_SWAP       = y
#   SWAPFILE_SIZE      = 64m

Is there a way to give the monitor more flexibility to deal with 
fullscreen games that try to change the settings?

Thanks,
