After doing
Code: Select all
InbvAcquireDisplayOwnership();
, how to get back from VGA mode to normal one? It must be possible because, when setting computer to sleep with media keys and waking it up, screen becomes normal again. What part of Windows handles computer sleep function?
I also saw function
Code: Select all
InbvSetDisplayOwnership
in ntoskrnl.exe, but it isn't exported. How do I call unexported Windows functions?

This is probably 2nd time I'm working with drivers, so maybe these links will help. I have no idea what to do.
