No output on HDMI2 with Intel HD Graphics 3000

Hi! I'm having trouble getting dual screen to work with Intel HD Graphics 3000 on a Intel DH67BL motherboard.

The DVI output is connected to my monitor, while the HDMI is connected to my TV (Samsung UE32B6000). DVI output is working fine. Upon connecting the HDMI output to my TV, it is recognized by xrandr:

$ xrandr -q

   720x400        70.1  
DP2 disconnected (normal left inverted right x axis y axis)

I can also see the monitor in Gnome 3 Display settings. Now, when I switch my TV to the appropriate HDMI channel, it says the source is not connected.

More details:
- I've made sure the HDMI cable works;
- The HDMI output is enabled in the BIOS. The BIOS is also updated to the latest version;
- Enabled the screen in Gnome 3 display properties and set the correct resolution;
- I'm using the stock xf86-video-intel drivers with no additional Xorg config;
- I've tried adding the following to the '10-monitor.conf' file in /etc/X11/xorg.conf.d:

Section "Device"
        Identifier      "intelsnb"
        Driver          "intel"
        Option          "monitor-HDMI1" "DVI"
        Option          "monitor-HDMI2" "HDMI"
        Option          "RandRRotation" "on"
EndSection

Section "Monitor"
        Identifier      "DVI"
        Option           "PreferredMode" "1680x1050"
        Option           "LeftOf" "HDMI"
EndSection

Section "Monitor"
        Identifier      "HDMI"
        Option           "PreferredMode" "1680x1050"
        Option          "Rotate" "CCW"
EndSection

Section "Screen"
        Identifier      "Screen0"
        Monitor         "DVI"
        Device          "intelsnb"
        DefaultDepth    24
        SubSection "Display"

                Virtual 3360 1680
                EndSubSection
EndSection

Any ideas?

No solution for you, but if you have any luck, please post. I am going to be trying to get my 3000 graphics up in the next week or so, and am not finding much info.

Ok. I found out that the HDMI-output works when I only connect the TV to the PC. When I try to use the DVI and HDMI outputs simultaneously, the TV displays the "source not connected" error, while my monitor works fine.

Have you tried it already?

Any other suggestions?

I think the reason is that you have only 2 CRTCs (cathode ray tube controllers), i.e. at a given time you can only have 2 working monitors, although more are connected. Check the output of:

$ xrandr -q --verbose | grep CRTCs

Mine looks like this:

        CRTCs:      0 1
        CRTCs:      0 1
        CRTCs:      0 1
        CRTCs:      0 1

which means that I have only two CRTCs with numbers 0 and 1. There are 4 rows, since I have 4 outputs LVDS-1, VGA-1, DVI-D-1, and HDMI-1.

boomerang · 2011-10-29 22:41:50

I seem to have two CRTCs:

$ xrandr -q --verbose | grep CRTCs
	CRTCs:      0 1
	CRTCs:      0 1
	CRTCs:      0 1
	CRTCs:      0 1
	CRTCs:      0 1

So I can have two working monitors connected, in my case HDMI1 (monitor) and HDMI2 (TV). There are no other monitors connected:

$ xrandr -q --verbose | grep connected
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 connected 1920x1080+0+0 (0x46) normal (normal left inverted right x axis y axis) 509mm x 286mm
DP1 disconnected (normal left inverted right x axis y axis)
HDMI2 connected 1920x1080+0+0 (0x46) normal (normal left inverted right x axis y axis) 160mm x 90mm
DP2 disconnected (normal left inverted right x axis y axis)

I had HDMI connected and either a vga or DVI, but the vga or DVI display "shuddered" the entire time it was connected, so I pulled it. Now I get an initial boot with HDMI, then I get a black screen unless I use acpi=off in the GRUB_CMDLINE_LINUX_DEFAULT= entry of Grub2. I had to use that to fix the same problem with DVI earlier.
Edit:
While this worked with the DVI output, with HDMI I am now getting these errors:

WARNING: Error inserting i2c_algo_bit (/lib/modules/3.0-ARCH/kernel/drivers/i2c/algos/i2c-algo-bit.ko.gz): No such device
WARNING: Error inserting intel_agp (/lib/modules/3.0-ARCH/kernel/drivers/char/agp/intel-agp.ko.gz): No such device

which occur when I try to start x, or if I modprobe i915

I've found a possibly related bug at the freedesktop.org bug tracker.

However, I can't reproduce the following part:

It is possible to get both screens working (under Ubuntu Oneiric), by turning
off the Dell monitor using the Displays control panel, then cancelling the
change when the control panel asks if the display is correctly set. Upon
reverting to the "previous settings", the Dell display is correctly
initialised, and both screens can be used.

On intellinuxgraphics.org it is suggested to provide the 'intel_reg_dumper' output in bug reports. I don't know if it's useful, but I've uploaded the output here.

Is it normal to have the DVI output labelled as HDMI? On all my systems I'm sure they were labelled DVI-0 and the like.

Possibly the HDMI and DVI outputs are sharing the same controller? Does outputting both at the same time work in windows?

I don't know if this is normal. In the bug report I've mentioned before the outputs are also labelled as HDMI-1 and HDMI-2.

I didn't test it in Windows. However the intellinuxgraphics website suggests there is dual head support for the intel driver. In this example dual head is configured for LVDS and VGA, not for DVI and HDMI.

[edit]
I've found this on the intel site:

Support for HDMI, DisplayPort*, eDP and DVI 2: High Definition Multimedia Interface (HDMI) delivers uncompressed HD video and uncompressed multi-channel audio in a single cable, supporting all HD formats including 720p, 1080i and 1080p. Dual independent display expands the viewable workspace to two monitors.

Apparently it isn't possible to use the DVI and HDMI outputs simultaneously. I've found this message on the bit-tech forums:

[...] but you have to connect one monitor with VGA and the other with HDMI/DVI - cant have two 'digital' connections unfortunately. I use the integrated HD 3000 graphics and it runs them fine with no hiccups [...]

If this helps at all, I am using HDMI and DVI output on Intel HD 3000 graphics. It is working. Briefly, my setup is an ASUS P8Z68-M Pro with onboard HDMI, displayport and DVI. i7 2600K. Kubuntu 11.10. Samsung 1920x1200 monitor in portrait and a Dell 1680x1050 landscape. I have desktop effects working in KDE. My Samsung is a DVI only monitor connected with a DVI/HDMI adapter to the HDMI port. xrandr reports that the monitors are HDMI1 and HDMI3. I am not using an xorg.conf and I am just using the monitor settings in KDE to set the default resolutions, orientation and 'leftof'. The system is stable and a couple of quick font anti-aliasing tweaks and I have a really nice looking setup.

This required no special config other than the settings in KDE as mentioned. I will be messing with my xorg.conf because the KDM login looks horrible (all messed up) because the settings aren't getting made by KDE yet at that point. So the default config seems to be going with 1440 which is a supported res on the dell (primary display) and then it tries that on the samsung as well where it is not a supported resolution. Once I login and KDE starts, everything gets set correctly and looks great. If you have other questions, let me know.

I've seen some conflicting information about this chipset and dual digital displays. Some say it's a driver issue and some say it's a physical incompatibility, but at the moment it looks like connecting one via VGA and the other via HDMI would be the simplest option for now.
