[SOLVED] Intel Card, LM17, Compiz, HDMI problems
I use LM17, with mate, with compiz on a recent Clevo computer, with Intel i3 Haswell and a integrated Intel HD4000 chip.
The problem comes when I changes something in the « display » program : changing the screen resolution, in the options, or adding a new screen/projector.
What I get with the projector is a flickering, unresponding screen on both the screen and the projector.
What I get when changing the resolution (from 1600×900 to 1440×900) is this : http://lehollandaisvolant.net/img/7Capture.png (here I tried with "xrandr", but the problem is exactly the same. As you can see, the image is not resized but cut off. The screen is no longer responding, only the mouse pointer is.
However, when I click somewhere, I can launch programs (if I click on the right spot) but I don’t see them : the image remains the same.
To get things working, I have to kill X-server (killall x-session-manager) in a TTY (Ctrl+Alt+F2). The the sessions shuts down, and I can reopen a new one (Ctrl+Alt+F7/8) with the two displays working fine.
When I want to remove the projector/screen, the same happens : flickering, unresponding screens…
I suspect my computer to be a bit to recent (March 2014) for LM17. For the past years, I got 3 recent computers, with 3 intel chips and everytime I had weird bugs that were solved over the time.
However, I just want to be sure : does anyone else have a similar problem ? Does it affect only Intel chips ? Is it compiz ? Mate ?
Thanks for any help you may be able to give me.
