00:02.0 VGA compatible controller : Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 09) 00:02.1 Display controller : Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a43] (rev 09)
With 2.6.32-573.26.1.el6.i686 my HDMI1 connected monitor works perfectly, and xrandr shows both VGA1 and HDMI1 connected.
With the -642 kernel, the HDMI1 screen goes blank as soon as the kernel loads.
If I connect a VGA monitor to the VGA port, I can see the system boot. The HDMI1 monitor remains blank.
After starting X, xrandr show HDMI1 disconnected.
Has anyone else seen this?
