Hello Again!

I found that the problem is related to the nvidia Separate X-Screen (X-Screen 0 and X-Screen 1) in nvidia driver setting ( it's what i use in my ubuntu 10.04 with gnome 2.3 and have no trouble) ! If i use Standard X-Screen 0 for my computer (Res:1600x900) and my TV Hdmi 42 (1920x1080), chrome and chromium minimize without any trouble, but if i use separate x-screen, the trouble appears only on Chrome family and not in other browsers (test with Firefox for the moment) . This config (Sep X-Screen) work's fine in gnome 2.3 in ubuntu 10.04 (I still use it today in Trial Boot, 1-Ubuntu 10.04 LTS, 2-Windows 7, 3-Ubuntu Test). Ubuntu test is for 14.04 LTS and MATE 1.8.1 and it's actualy the best choice and result for me after a number of tests with all ubuntu distribs (12.04,13.10 and 14.04 now)!

So, I am still waiting for your opinion on this bug !

Can you reproduce this issue with a stock Ubuntu 14.04 or 14.10, not MATE, but Unity?

Hello, Again !

First, I apologize for the few English mistakes,I'm French and I don't practice it a lot more now ! To Answer your question and and as I have already pointed in the first description, I've try it in Unity, no trouble appears, chrome and chromium operate normally in all function with Nvidia driver in Normal mode or in (Separate X-Screen, Although it does not work properly on unity, while it works fine on MATE!) and so i can't reproduce this bug in Unity, because chrome family work's fine in this desktop as other browsers ! I've test it in other desktop like XFCE, or Gnome Session Fallback in UBUNTU 12.04, and I have not found identical problem to this one !

Hope my comment will help you for your quest of a solution for this bug, not critical but annoying to use !

Best Regards !

I'm undecided as to whether or not this affects me, or is by design. Both the following machines are single-boot machines, running combined SSD+HDD on UEFI motherboards.

Machine 1:
Ubuntu 14.04.1 LTS default install from ISO. Unity purged, MATE installed from PPA (http://repo.mate-desktop.org/archive/1.8/ubuntu). Intel video (i915). Compiz installed + enabled. Dual monitors (one HDMI, one analog)

Machine 2:
Ubuntu 14.04.01 LTS upgraded from 12.04 ISO. Unity purged, MATE installed from PPA (1.6 originally, 1.8 now). NVidia GT 3800 (304), dual DVI monitors . Compiz installed + enabled.

With Firefox, full-screen on either monitor (F11), moving the mouse to the top of the screen displays the address bar/minimise/close icons.

With Chrome, full-screen on either monitor (F11), moving the mouse to the top of the screen displays a message about being in full-screen. It does not show the address bar/minimise/close button.

With chromium-browser, full-screen on either monitor (F11), moving the mouse to the top of the screen displays a message about being in full-screen. It does not show the address bar/minimise/close button.

(For completeness' sake)
With Opera, full-screen on either monitor (F11), moving the mouse to the top of the screen shows nothing. On initial keypress, a large notice saying "press sec to exit full-screen mode" id displayed. Controls to minimise from full-screen are not shown.

With Midori browser, full-screen on either monitor (F11), moving the mouse to the top of the screen shows nothing. The only way to exit full-screen is to press F11.

The actions are the same on both machines, despite the mix of drivers/video hardware/source install, which leads me to think this particular behaviour is by design for Chrome/chromium.

As a side note, I also tested "maximised" rather than full-screen. The minimise works as intended on both monitors. I've also never had any issues as described when using external monitors on my laptop (14.04 LTD upgraded from 13.04, dedicated NVIDIA card, external monitor via mini-VGA or HDMI) - I've used Chrome a lot on external HDMI displays driven by the NVIDIA card with no issues - and with no "minimise" icon, only the "exit full screen" notice.
