           Summary: Regression since V6.0.3: Using NVIDA Optimus WINE
                    V8.02 - V8.16 unable to create windows.
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: winex11.drv
          Assignee: wine-bugs@winehq.org
          Reporter: gavron@wetwork.net
      Distribution: ---
REGRESSION: Everything works on WINE 6.0.3
Under WINE 8 (Stable and Devel) no app windows open.  Even winecfg will not
open.  After changing the display mode to 'intel' everything works.
After changing it back to 'nvidia' and no other changes this error repeats:
0188:err:winediag:nodrv_CreateWindow Application tried to create a window, but
no driver could be loaded.
0188:err:winediag:nodrv_CreateWindow L"The explorer process failed to start."
Method to reproduce:
$ sudo prime-select intel && reboot
--wait for reboot--
$ winecfg
--works just fine--
$ sudo prime-select nvidia && reboot
--wait for reboot--
$ winecfg
--fails with many of that same error above--
$ sudo prime-select intel && reboot
--wait for reboot--
$ winecfg
--works again... the only change being switching the display driver back and
forth--
