Dual head Intel i7-2600S and DQ67SWB3
debian-user: I'm attempting to get a dual head setup working using an Intel i7-2600S processor, Intel DQ67SWB3 motherboard, and Debian GNU/Linux. (See end for console session.) The DVI (Blue) Analog port is configured as primary in CMOS setup, and connects via an Intel DVI/ VGA adapter (furnished with motherboard) to a Nokia 445XiPlus 21 CRT monitor. The DisplayPort port is configured as secondary in CMOS setup, and connects via a StarTech DP2VGA2 DP/ VGA adapter to a Nokia 445Xi 21 CRT monitor. My OS is Debian GNU/Linux 6.0.5 amd64 (Squeeze). My kernel is linux-image-3.2.0-0.bpo.2-amd64 from Debian Backports. My X.org server is xserver-xorg-video-intel from Debian Backports. I booted in recovery mode and ran Xorg -configure to create an xorg.conf.new file. I temporarily connected the 445Xi to the DVI port and used get-edit | parse-edid to obtain an xorg.conf Monitor section. get-edid doesn't work for the 445XiPlus, so I created an xorg.conf Monitor section using specifications and cvt. I edited the above three into /etc/X11/xorg.conf. When I start the computer: 1. POST displays on both monitors (clone mode). 2. GRUB and the first part of boot only display on the 445XiPlus (445Xi is dark). 3. The latter part of the boot and the logon screen displays on both monitors (clone mode). 4. Once I logon, gnome-display-properties detects both monitors as Unknown. I can change to span mode and set the 445XiPlus to 1600x1200 87 Hz, but only the default settings are available for the 445Xi (e.g. 1024x768 60 Hz maximum). When I swap the motherboard/ monitor connections (DVI - 445Xi, DP - 445XiPlus), swap the xorg.conf Screen/ Monitor settings, and move aside ~/.config/monitors.xml: 1. POST, GRUB, and the first part of the boot only display in the 445Xi (445XiPlus is dark). 2. The latter part of the boot and the logon screen displays in both monitors (clone mode). 3. Once I logon, gnome-display-properties detects the 445Xi as Nokia Display Products 19 and the 445XiPlus as Unknown. I can change to span mode and set the 445Xi to 1600x1200 75 Hz, but only the default settings are available for the 445XiPlus (e.g. 1024x768 60 Hz maximum). Plus, making more than one change can result in the the XiPlus going dark and staying that way. I've played with various permutations of CMOS settings, motherboard/ monitor connections, xorg.conf Monitor modeline settings, gnome-display-properties settings, etc., but the results were confused at best. Any suggestions?

Re: Dual head Intel i7-2600S and DQ67SWB3
Hello David, I am a bit confused about your actual aim: Do you want both screens in clone mode all the time, or in clone mode during boot and span mode within Gnome?

If your preferred mode of operation is not available here, you can try to add it using xrandr --newmode before then switching to it. The manual page on xrandr is quite good, I think. [ 457.588] (II) LoadModule: intel The intel graphics driver should support that :) I don’t think you need the xorg.conf file.

Thanks for the reply. :-) My goal is at least one monitor displaying during POST, GRUB, boot, and login, and then span mode 2 x 1600x1200 on the desktop. The Nokia 445Xi can do 75 Hz and the 445XiPlus can do 87 Hz at that resolution, but I would settle for 75 Hz on both monitors.

STFW I've posts about xrandr, but I'd prefer to get this working via CMOS settings, motherboard/ monitor connections, xorg.conf, and gnome-display-properties. I'll play with xrandr in any case.

Hello David, David Christensen dpchr...@holgerdanske.com wrote: My goal is at least one monitor displaying during POST, GRUB, boot, and login, I think you already achieved that? and then span mode 2 x 1600x1200 on the desktop. The Nokia 445Xi can do 75 Hz and the 445XiPlus can do 87 Hz at that resolution, but I would settle for 75 Hz on both monitors. That’s two calls to add the corresponding modes and two calls to set these modes for each of the monitors, in total four lines in an autostart script in your Gnome session. STFW I've posts about xrandr, but I'd prefer to get this working via CMOS settings, motherboard/ monitor connections, xorg.conf, and gnome-display-properties. I'll play with xrandr in any case. gnome-display-properties is mostly a front end to xrandr from what I can tell, but it also allows you to add new modes (though you obviously should make sure that your monitors support them). I think CMOS settings mostly apply to the BIOS, GRUB and maybe boot, but I have to admit I never really understood how the Linux kernel decides where to show its virtual terminals. Anyway, I fear I can’t really help you with CMOS and boot, and there are certainly people who are more knowledgeable about xorg.conf on this list. :) Best regards, Claudius -- Forgive and forget. -- Cervantes http://chubig.net telnet nightfall.org 4242 signature.asc Description: PGP signature
