Can't start games

[qalimas]

When I try to start any 3d game, such as Savage or Neverwinter Nights, I get this error message:

keith@game-desktop:~/savage$ ./savage

Gdk-WARNING **: locale not supported by Xlib, locale set to C

Gdk-WARNING **: can not set locale modifiers
System_Init()
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 134 (XFree86-VidModeExtension)
Minor opcode of failed request: 10 (XF86VidModeSwitchToMode)
Value in failed request: 0x115
Serial number of failed request: 104
Current serial number in output stream: 106



Can anyone please help me? I have a presentation to do soon on gmaing on Ubuntu for my LUG, but I need gaming to work first (I just redid the system from a huge hdd crash, it worked fine before then, I swear :P) ](*,)

see if you can use a lower refresh rate, digging around trying to solve the same problem, and that seems to be a possible solution.
