Видимо, не повезло с экземпляром
Поставил nouveau, сравнил. Пока работало - успел оценить производительность - примерно в 3-4 раза ниже, чем nvidia. В частности, kairo, который у меня в полных настройках буквально летал на 2560х1440 (60 fps, vsync и всё такое), показал что-то порядка 10 fps в тех же условиях.
На двух разных видах драйверов я получаю квадратики с мусором на экране - чистой воды проблемы с памятью видяхи.
Зато nouveau более детальна в своём недовольстве (хотя так же виснет):
