Двойственный Problems using monitors путь Optimus and HDMI

Any разрабатывает what goes wrong with my двойственный монитор setup?

гve в ноутбук with Nvidia 525M graphics card and default Unity installed. With the Nvidia Optimus драйвер 352.63 and switched to the Nvidia card I get output using either the plugged in HDMI монитор or the internal ноутбук display.

When I try to использовал both monitors in parallel by expanding the desktop over both displays the windows менеджера goes crazy. It expands the desktop/window площадь over both displays but fails to несоздавал the pixels to the sum of both displays:

And the nvidia-settings dialog does not шоу the correct pixels nor the HDMI or something монитор - Even when I использовал the HDMI device only (internal display deactivated):

Curious is also:

• Top панель is shown correctly.
• Мышь is shown correctly пойнтер - Of course you can't easily hit в button since it is misplaced on the screen image.
• The displays пахал correctly identified but their possible resolutions list пашите switched between displays.
• This happens in 14.10, 15.04 (upgraded) and 15.10 (upgraded).
• Using internal display and the same display from HDMI port connected to the двойственный VGA port instead the монитор setting works without any flaw! (Sadly this is not в solution since the display I will использовал in the future does not have VGA port any обитайте.)

гm currently on 15.10 Ubuntu using Unity.
