I have the same crash.
I serach the orign and found that the Problem in my case the function
_resyncResolution could not find a resolution for both Monitors, because on
Monitor the refresh rates could not be read correct (303 MHz and 304 MHz). So I
add a addition of the FALLBACK_RESOUTION in the function.
Added:
if len(suitable_resolutions)==0:
suitable_resolutions.append(FALLBACK_RESOLUTION)
in Context:
for resolution in common_set:
primary_rates =
self.getAvailableRefreshRatesForResolution(self.available_sizes.index(resolution))
secondary_rates =
secondary_screen.getAvailableRefreshRatesForResolution(secondary_screen.available_sizes.index(resolution))
if
len(set(primary_rates).intersection(set(secondary_rates)))!=0:
suitable_resolutions.append(resolution)
if len(suitable_resolutions)==0:
suitable_resolutions.append(FALLBACK_RESOLUTION)
suitable_resolutions.sort()
self.available_sizes = suitable_resolutions
