            Bug ID: 56949
           Summary: Incorrect heuristic used in "winex11: Detect broken
                    NVIDIA RandR setups."
           Product: Wine
           Version: 9.9
          Hardware: aarch64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winex11.drv
          Assignee: wine-bugs(a)winehq.org

The commit
https://github.com/wine-mirror/wine/commit/8776e1c0e1597fec169d169888660deb5...
uses an incorrect assumption heuristic where a display with only one possible
resolution output must be using a bad driver version. this is an incorrect
heuristic as some displays (such as embedded display panels) only have one
supported resolution and cause wine to fallback to using RandR 1.0
unnecessarily.

This heuristic causes users of such devices (such as the Nintendo Switch with
its builtin screen) to incorrectly think that the driver is old or needs to be
replaced.

Example proper xrandr output from such a device:

xrandr --verbose
