Hey to all,
maybe this Q&A is of common interrest:

A:
 setmon -x 1024x768_96s, and restarting X, should do the trick.

 The different vofs are in /usr/gfx/ucode/MGRAS/vof. 2RSS subdirectory
 for Max Impact. 6.2 for latest modes (including working 1600x1200),
 patch 1223 for max number of vofs in 5.3.

A:
 That's why I said setmon -x 1024x768_96s (note -x)
 and then restart the X server. You can't load a vof on-the-fly that needs
 reconfiguring the framebuffer, hence the error. The error tells you it can't
 find a vof for on-the-fly switching.

 1280x1024_76 and 1280x492_120 use the same framebuffer config.

 You can also add that on *Maximum* Impact, switching between vofs
 on-the-fly can work for more combinations, as the framebuffer is wider, hence
 Reto's post that a setmon -n worked for him.

 Using setmon -x and restarting X works for all Impact machines, though; that's
 why I got used to it.
