- The problem could be with the combination of virtual resolution and modes
- you have selected. The actual virtual resolution used is
-
- max(mode X sizes) x max(mode Y sizes)
-
- So it is possible that all modes and the virtual size specified in Xconfig
- fit separately into 1MB, but that the final virtual size used is too large.
-
- Also, for the mono server, only 64KB is used, which means that the max
- virtual size is about 800x655.
