i use suse linux 13.1.

i have an optimus system so nvidia (NVIDIA® GeForce® GT 620M) and intel graphic (intel 4000) card in my lenovo s430 laptop ( http://www.notebookcheck.net/Intel-Core-i5-3210M-Notebook-Processor.74458.0.html Core i5-3210M)

.

xrandr --listproviders

Providers: number : 2Provider 0: id: 0x92 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 7 associated providers: 0 name:IntelProvider 1: id: 0x62 cap: 0x7, Source Output, Sink Output, Source Offload crtcs: 2 outputs: 1 associated providers: 0 name:nouveau

ls /sys/class/drm/*/status | xargs -I {} -i bash -c "echo -n {}: ; cat {}"

/sys/class/drm/card0-DP-1/status:disconnected

 

/sys/class/drm/card0-DP-2/status:disconnected

 

/sys/class/drm/card0-HDMI-A-1/status:disconnected

 

/sys/class/drm/card0-HDMI-A-2/status:disconnected

 

/sys/class/drm/card0-LVDS-1/status:connected

 

/sys/class/drm/card0-VGA-1/status:disconnected

 

/sys/class/drm/card1-VGA-2/status:connected

so everything is connected to the intel card.

i have a hdmi port and a display port.

so i connected a monitor to my hdmi port (HDMI-A-1".

i also connected a monitor to my displayport (with a displayport to dvi cable)

ls /sys/class/drm/*/status | xargs -I {} -i bash -c "echo -n {}: ; cat {}"

/sys/class/drm/card0-VGA-1/status:connected

/sys/class/drm/card1-DP-1/status:disconnected

/sys/class/drm/card1-DP-2/status:disconnected

/sys/class/drm/card1-HDMI-A-1/status:connected

/sys/class/drm/card1-HDMI-A-2/status:connected

/sys/class/drm/card1-LVDS-1/status:connected

/sys/class/drm/card1-VGA-2/status:disconnected

so display port seem to be HDMI-A-2.

When i enable all my monitor (2 screen monitor + laptop screen), i can get a full resolution for the laptop screen but only 800x600 on others monitor.

my kernel drive it's 3.12.

I don't know if it's a limit driver or it's a physical limit?

Hi marc.collin,

When using triple display, the resolution in the configuration will be limited depending on the resolution you use in the main display.

You can check more information at the following link about this configuration:

http://www.intel.com/support/graphics/sb/CS-033714.htm http://www.intel.com/support/graphics/sb/CS-033714.htm

It is important to mention that the supported operating systems on Intel products are windows versions only so you may try the triple display configuration with Windows since we do not know if the kernel can be limiting the resolution.
