I solved this on my machine by, Go to the System menu, then Administration and Hardware Drivers Select the latest version (recommended) nvidia driver. (bottom option) Let it download, select apply and restart. This should install a later version eg 195, which seems to resolve the problem. Hope this helps. Leona
