fvwm would quit when there were no screens detected by RandR. However, this can be problematic with laptop screens which can be turned off. If fvwm receives an RandR event to rescan screens, that can therefore cause RandR to tell us there's no screens found. This is not true though since the number of *configured* screens from fvwm's perspective is still the same. In such cases then, fvwm should only quit when the number of configured screens is 0 *and* RandR hasn't detected any screens either. Problem reported by @farhaven (Gregor Best)

fvwm would quit when there were no screens detected by RandR. However,
this can be problematic with laptop screens which can be turned off.
If fvwm receives an RandR event to rescan screens, that can therefore
cause RandR to tell us there's no screens found. This is not true
though since the number of configured screens from fvwm's perspective
is still the same.
In such cases then, fvwm should only quit when the number of configured
screens is 0 and RandR hasn't detected any screens either.
