Ticket #56: 1005-remove-fbbase.patch

File 1005-remove-fbbase.patch, 2.5 KB (added by Antoine Martin, 7 years ago)

dummy randr 1.2: patch 5 Get rid of dPtr->FBBase

  • src/dummy.h 

    The pointer to the screen's pixels is stored in the screen pixmap's
devPrivate.ptr field.  Just use that instead of storing it
redundantly.

In addition, don't leak the screen if the server was VT switched.
