HD4000 Graphics. Fine tuning on Multiple screens Pls.

business_kid · 03-20-2015, 02:34 PM

I am trying to set up xorg.conf.d for running Extended mode on my HD4000 graphics. I'm close, but not quite there. My setup is
Screen0: Main Screen 1600x900
Screen1: HDMI at 1920x1080 OR 1280x720
Screen2: The VGA Plug – Resolution?? (I have 1440x900 atm)
I can use screen 1 or screen 2 but not both. I am not trying to break records.

Xorg does start each screen at an appropriate resolution. But it sets a Virtual screen on the bigger one and ignores my left/right stuff. It's trying to clone them. I thought the HD4000 did some extended mode where 2 screen sizes were belted out? Has anyone got that singing?

Below is the pertinent parts of /etc/X11/xorg.conf that I've used the last couple of years. The CPU is an Intel i5-2400. Both of my screens are identical.

Perhaps something in my dual screen configuration will help some.

Yeah, thanks - I will borrow a line or two. Yours is well laid out. But for your set up, cloning screens will work. For mine, it won't. with 2 @ 1920x1080, you can set a Virtual Screen size. I can't.

My 1600x900 laptop screen is unlike anything I am plugging in.
HDMI gets monitor at 1920x1080 and a projector at 1280x720
VGA gets monitors at up to 1440x900.

So I can't set Virtual Screen size; that's the big issue. And I can't set modes. I am getting my biggest screen cloned, when I want the Extended thing with separate outputs. I don't even know if the HD4000 support that fully. Intel _SAY_ it does, but vlc keeps throwing errors about 'can't resize display'. when you run a movie. Mplayer does better.
