Description Porcupine of the Moon 2011-10-11 20:24:49 UTC

I have an odd behaviour of my dual-screen setup. I'm using Gnome 2.31.1. I did not edit/create a xorg.conf. Instead I'm just using gnome-display-properties.I have no separate graphics card. I'm using the integrated one of my Intel core i5 2500k CPU. That is Intel GMA with i915 driver. One Monitor is connected over DVI and the other over VGA. 

Everything is working fine except one problem:
After I put the PC in suspend or after I switch to a console with Ctrl+Alt+Fx only one monitor (VGA) is getting on again.
The DVI-monitor stays off. The only two methods for activating them again I found are restart of the xdm-init-script or open gnome-display-properties on the remaining monitor and switch the DVI-monitor in this window off and on again (it is not physically switched on and off, only via software). After this both are working normal again.
If I switch to the console sometimes only the VGA-monitor shows an image an the DVI-monitor is off. 

I could solve this problem by upgrading to the testing version x11-drivers/xf86-video-intel-2.16.0.

Reproducible: Always

Steps to Reproduce:
1.Suspend the PC.
2.Switch the PC on again.

or
1. Switch to a console (e.g. CTRL-Alt-F1)
Actual Results:  
The monitor connected to DVI is/stays off. The monitor connected to VGA is working normal.

Expected Results:  
The monitor connected to DVI should show an image.

Thank you for the report, but there is nothing to do for us in this case. xf86-video-intel-2.16.0 is planned to go stable after kernel 3.0 goes stable.
