Two separate VIA video chipsets – completely different in every way, are not well supported with OpenChrome. One works…poorly. And the latter is a flat out fail regardless of how many times I recompile the latest video drivers.
For myself personally, I might find myself a bit more excited about the prospect of them joining the open source ranks if I believed that such an event would help the OpenChrome project to fix these on-going bugs. Sure, file a report…then watch it be either labeled fixed or dismissed. Forget it, skipping VIA is the real solution.
