Grub2 booting with dual monitors no display (flickering)

Just finished my first installation of Arch and run a Dell Latitude E6410 at work with a dock and a large external monitor hanging off the VGA port. When the machine boots up after initial Dell screen, I get mostly a black screen with some lines of colour on the display, eventually after the usual grub timeout I see that it starts booting. I've messed with the /etc/default/grub file and changed the GRUB_GFXMODE to something in the range of hwinfo --framebuffer with no luck (Im redoing the grub-mkconfig command after changes).
I've recently undocked the laptop and booted in a single screen and grub works perfectly, so there is obviously some issue with what display it should use or that its trying to span it across the whole range.
Can anyone share some advice on where I need to go from here?
Thanks

I've been doing some extra work to try and resolve this and I'm coming up with not many more ideas. If anyone can point me in the right direction log file of config file, that would be great too!

How to setup Cintiq 12wx along with dual monitors (3 displays total)

I’m considering purchasing a Wacom Cintiq 12wx. I currently run the latest LR and Photoshop CS5 with two NEC P221W monitors (which I keep color-calibrated) on Windows 7, set up with my desktop extended across both displays. They are both running at their native 1680 x 1050 resolution (and I want to keep them that way). My video card is a GeForce 8800 GT. Dell XPS 630i.
I want to run the 12wx (whose resolution is 1024 x 1280) in addition to the above setup. The best advice I can find so far on the web is to get another (cheaper) NVidia card to run it. Sounds right to me. My question (assuming this is the way to go): how should/can the Windows desktop/monitor setup be configured to handle this?
My desired Lightroom result is:
* grid/develop view of image on my main NEC
* image only on the second NEC (F11) – this is what I have so far
* editable view of the image on the Cintiq
My desired Photoshop result is:
* editable image view only (well, mostly) on my main NEC
* tool panels etc. on the second NEC (configured via Workspace) – this is what I have so far
* editable view of the image on the Cintiq
Has anyone done this, if so how? Also, I’m hoping I can color-calibrate the Cintiq as well as the two NECs, thoughts?
Thanks.

Thank you Grant for the quick response. Well, it seems I don't know what I'm doing.
So, Mac Pro doesn't have any video INPUTS just Outputs. CHECK.
That is correct I have a six-input-port-selector with one input (SWITCH C2G). CHECK.
What I want is to be able to toggle through the inputs from the HDMI Switch C2G. That way I can use all my devices (Mac Pro, Xbox, PS3, Cable Box) with these monitors.
Since the Switch C2G only has one OUTPUT Slot, I'm thinking I just need to connect the monitors to the Switch C2G Output slot by using a 2 to 1 HDMI Adapter, but wouldn't I lose the true potential of these monitors by not connecting them directly to the Mac Pro?
Currently, I have the monitors hooked up with Thunderbolt/Mini Display Adapters to the Mac. So I guess I would just have to run just one HDMI with Thunderbolt/Mini Display from the Mac to the Switch C2G, and connect the other devices to the Switch as well.
Jeez. Am I right?
What If I get an HDMI Switch with 2 Outputs instead of getting the 2 to 1 HDMI Adapter or perhaps a 4 to 2 Adapter. Heck. I'm not sure what to do here.
I would really appreciate anyones help.
Thank you.

Gnome Crashes on Login after messing with dual monitor settings

Gnome displays the sad monitor and has the error message "..something has gone wrong..~" and will force me to log out. I've only started to experience this after messing with dual monitor settings in nvidia. The dual setup(twinview) worked but once I rebooted, I couldn't get it going for awhile.
Here's my xorg.conf

Extra Notes: I have another desktop session with awesome installed(uninstalled now) and could log into that no problem. Awesome was giving me troubles so I uninstalled it. I have 2 gnome desktop sessions, my regular gnome session(the one that crashes), and the other with no window manager(never crashed on startup).
I installed awesome around the same time as configuring the dual monitor setup.
Thanks.

Update.
The crashes are to be expected now. I'm circumventing the whole thing by logging into my other Gnome session without a window manager, logging out and then logging back into my regular Gnome with Metacity.
I've noticed the tty1 sessions(not sure what's it's called) is strange. Apparently my session runs on tty8 but when I try logging in, it'll crash me and tty7 gives me a blank screen with a blinking underscore. The other tty1s work regularly. Not sure if this has anything to do with it.
Is there a way to just reset the Gnome settings?

Unwanted keyboard shortcut with dual monitors

Problem:
I have a computer setup with dual monitors (desktop extended). When I have a window open, e.g., Microsoft Word 2007, after I type "1" on the keyboard, the Word Window and mouse relocate to the second monitor. When I type "2" the Word window and mouse relocate
to the main monitor. In the word document, 1 and 2 are typed in the document, but pushing the keys still move the window and mouse to the opposing monitor.
I checked the keyboard settings within Windows and found that sticky keys and such are not enabled. The keyboard has no such features to enable. I also checked the display setup in display properties and found nothing that would indicate such a setup. Google
searches return nothing related to my problem.
What I do know:
-The rest of the numbers on the keyboard work fine. Pressing 1 and 2 on the number pad at the far right of the keyboard do not transfer the active window to the second monitor. Those keys work fine.
-The type of window does not matter. Using notepad, word, excel, internet explorer, sticky notes; all of those windows would transfer to the opposing monitor when I push 1 and 2.
Setup:
Windows XP
Dual-Monitor
Wireless Keyboard and mouse

This pertains to StarTech DVI to USB adapters.
There's an icon in your system tray near the clock, either super utility or usb display device. Right click, and select multi display control panel.

There's a button to disable as long as you have the newer driver from their website. The old drivers had a bug that caused this button to not work

Interfacing with dual-monitor machine

Hello all--
I've got a G5 at home with dual monitors on which I run 3D animation software with lots of panels. I'd like to be able to control the G5 from work using a laptop (possibly also connected to an external monitor). Is it possible to display both screens of the desktop using ARDv3 on the laptop? Some users have mentioned they can do this but the size of the remote screens is unsatisfactory. So, again, can you visualize both screens well via the remote computer?
Thanks for any help you can offer.

you can view both screens at once but it will be scaled to fit on the screen you have... so what you see is dependent on the resolution of both client monitors and your admin computer's monitor.
you can also select to view a single monitor of the client computer.
i've never run ARD admin on a computer with 2 monitors so i'm not sure how it handles it but i'm guessing that you can view both monitors on both admin monitors.... it'll probably scale down or up dependent on resolution.

Run screensaver independently with dual monitors

I was wondering whether, when running OS X with dual monitors, it was possible to run the screensaver on one of the monitors (while still using the other)?

Nope. Can't do it.

Need to launch Organizer Twice to work with Dual Monitors

If I open a project or either Photoshop Elements 10 or PRE10 and then click on Organizer it loads, but sits in the taskbar below. If I hover over it the AERO Windows (Win 7) pops up showing it's loaded. But It will not maximize. This is when I had last used it on a second monitor so I can easily compare before and afters. However, if I right click on it and close it, then reopen it, it launches perfectly in the 2nd monitor. Does this every time. I ussually leave it open all the time now to avoid this but I don't know how sesitive the catalogs are if the system is rebooted for some reason.
I did no specific configuration for dual monitors, Just dragged it over there when I wanted to use it.
Thanks,
Joe..

Hi Joe,
This is a known issue with dual monitors and got to know that Organizer people are tracking it as a bug for now.
Hope this will be fixed soon.
Thanks

[SOLVED] openbox margins with dual monitors

Hi community,
I have stumbled to a nasty problem on my first incursion to dual monitors in openbox.
I'm using xrandr with this command (which works just fine BTW):
xrandr --output LVDS --mode 1280x800 --primary --output VGA-0 --mode 1280x1024_60.00 --gamma 1.0:1.4:0.85 --right-of LVDS
and have set a Virtual screen in xorg.conf of 2560 x 1024 pixels.
But, my laptop monitor only handles 1280x800, while my external LCD monitor has 1280x1024, so there is a virtual area under my laptop screen which i'm not using, but i dont really care about that.
The problem is that when I'm setting screen margins, so that maximized windows will respect the panels in the bottom (tint2), in rc.xml (or by obconf) the margins are applied to the virtual screen and only are practical on the external monitor wich has more pixel height.
I'm really missing some kind of per monitor margin settings in openbox, maybe there is and i haven't found it? It makes me wonder because openbox can maximize windows to a single monitor, even if the whole layout it's treated like a virtual screen, so it has some way of distinguishing between them.
I would appreciate any suggestions, thanks.

TL;DR - I'm not aware of any acceptable solution at the moment.
Basically, what you're having problems with, is the "dead area." It can really be quite a pain in the butt if window managers or other screen aware applications don't anticipate it properly. To my knowledge, Openbox doesn't support margins on a monitor-by-monitor basis. In reality, you shouldn't need to be setting margins anyway. Tint2 should be reporting itself as a taskbar, and Openbox should be respecting that.
I have dead area too, with multiple monitors, and Openbox respects both of the KDE taskbars I have running (one on each monitor). (I use KDE and simply replaced Kwin with Openbox.) This tells me that tint2 should be able to cooperate with Openbox. I remember trying tint2 a while ago, and didn't fine it adequate in a dual monitor environment (it was probably a year ago or so). tint2 would need to be setting the _NET_WM_STRUT_PARTIAL hint, and I'm not sure if it is (or if it's doing it properly). See http://standards.freedesktop.org/wm-spe … #id2507618
Also, I do know that the developer for Openbox recently got a dual monitor setup, and she's been adding additional support for dual monitors a little at a time. Hopefully with 3.5, there will be a lot more support. (Margin support for multiple monitors would be great, because it could be a good utility knife for applications that don't care about multi-monitors setups and don't set the proper hints.)
If you're capable of modifying tint2, my course of action would be to try something that works (like the KDE taskbars) and record the hints being set there. Then compare them with tint2 and try to mirror KDE's setup. (If you're a programming lacking experience with X and related nonsense, I'd be more than willing to offer what guidance I have.)
Also, I developed a panel myself (and got pretty far along) using the PyGTK toolkit... But I can't remember if I solved this problem or not. I'll try to check it out and get back to you. (I got as far as implementing a widget system that includes a task list, system tray, clock, menus... It just isn't polished very well. My original intention was for it to be a more robust PyPanel with dual monitor support.)

Visualise Spots with dual monitors

I'm finding some eratic behaviour when using Visualise Spots with dual monitors.
I have Development open on one window and the Loupe view open on the other. When I click on the Visualise Spots both windows show the visualisation. When I click the button off - both windows switch to normal view - most of the time.
Occasionally it will switch off in the Development view but stay on the Loupe view on the second monitor. It only goes away when I switch to another image.
Is anyone else seeing this behaviour?
Roy

I have found that's it's linked to zoom level.
I can't quite make out what's going on but the behaviour is very strange.

Lync 2013, text does not display in chat box. Windows 7 pc with dual monitors.

Has anyone experienced an issue with Lync 2013 where when someone sends a chat the text doesn't display in the chat box. Or on occasion when initiating a chat, the text typed in doesn't display? The person experiencing this
behavior has dual monitors and often times when she is working on a document - then goes to Lync and initiates a chat and types, the words do not display in the chat box. Her graphics drivers are current, (8.15.10.2869). At one point she was able to drag the
chat box over to the monitor on the left and then the text displayed. Since then she has received a brand new laptop, windows 7 and the Lync behavior continues but now her dragging the chat box to other monitor no longer resolve text display issue. Ideas?

Hi,
Did the issue happen if only use single monitor?
Please update to the latest version for Lync client 2013 and then test again.
Best Regards,

The real problem is that the display on HDMI3 just isn't "waking up". The power is on, but it just sits there in sleep mode.
Any help would be great. I might just be missing something simple. Thanks.
Edit: I just saw a short list of window managers near the bottom of the Arch Multihead page (https://wiki.archlinux.org/index.php/Mu … _xorg.conf). I don't see openbox on that list. Does that mean I'm SOL if I want to use openbox with multiple monitors? This page seems to imply that it should work fine with openbox http://magnatecha.com/dual-monitors-wit … nd-xrandr/.

I use XFCE, and when I boot my computer I just run:
xrandr --output DVI-I-1 --auto --output DVI-I-2 --auto --left-of DVI-I-1
I'm assuming if you modify the names appropriately that it'll work too. I have had issues before trying to run dual monitors without taking both outputs off of a single video card (which is what I'm doing now). For example, I had a graphics card with one (VGA) output and a VGA output on my motherboard. But, connecting the graphics card disabled the on-board VGA. So it is possible (I'm not an expert here) that two displays coming off the motherboard may not work for hardware reasons.

New ATI 4870 - No Video with dual Monitors

I have just received my ATI 4870 and am having some very unique problems. I have a dual display setup (NEC 2690WUXi2, Apple LED CD) running as an extended desktop. I have 2 Intel SSD X25-M in raid 0 as my boot drive in bay 1 and 2 of my Mac Pro 2.26.
The ATI card will not supply video when booted from the SSDs if both monitors are hooked up. The video stops abruptly right after the NEC is fed a signal and both monitors go blank. If only the Minidisplayport is used I get video and can subsequently plug in the NEC to the DVI port for dual displays. If I boot from one of my outboard clones the system will give me video on both monitors. I am also able to boot successfully from a SATA clone in Bay 1.
The computer boots flawlessly with 2 monitors when using the stock GT120 video card - this is from any source SSDs, outboard, etc. I have a 'clean' install of OSX with no programs that also has the same problems - no video from the 4870 and works flawlessly with the stock GT120.
If both video cards are installed I have a flawless boot. The NEC is attached to the ATI card and the Apple LED is attached to the GT120. Everything works like a champ. My thoughts are that this may be some timing issue with the SSDs and the ATI card when used alone. I can't think of any other explanation. Does anyone have a suggestion if I want to use just the ATI card?

You're sig says you have a 2009 mac pro. If so, you shouldn't need the drivers anyway as your 10.5.6 preloaded should already be the "special" version.
The beta drivers link pretty much pertained only to 2006 to 2008 mac pros ordering the 4870. As their 10.5.6 was the "plain" version.
What might be a culprit is that apple is shipping updated versions of the 4870 (different device/revision IDs). The beta drivers were taken from pre-release builds of 10.5.7 sent to devs. Maybe the updated versions are not jiving with the beta drivers, and made in particular for 10.5.7.
Well if any consolation, 10.5.7 may be as close as this week.

T61 worked with Dual Monitors and now it does not

I'm having trouble getting two monitors to work. They used to work fine. There have been no changes to hardware. Now the DVI monitor is blank. The DVI monitor does work with other computers (I'm working through a KVM switch).
T61 running XP Pro
Docking station
Worked well in the past
Took laptop to a meeting and used VGA and Laptop displaying the same information (needed to fool around with a few things to get that to work (FN-F7, Presentation Director, not really sure what worked)
Came back to docking station and my second monitor does not work anymore.
Control Panel
Shows two monitors (1 Bright, 2 Grayed)
Can select and choose extend on the second monitor (1 Bright, 2 Bright)
Apply reverts to (1 Bright and 2 Grayed)
NVIDIA Control Panel\
Set up multiple displays show choice is Only use one display (Single)
Second monitor choice is grayed
Presentation Director
No option is shown for two monitors
Laptop and monitor choices exist
BIOS Display
Tried Internal and PCI options (no joy with either)
Display is set to VGA & DVI
Any suggestions??

The docking station is a type 2504. I have both the VGA and the DVI port hooked up to identical flat screen monitors. I have no intention of messing with that because the setup is working successfully via a KVM switch. Both ports and both monitors are working. However, there is a problem with swithching modes with the Lenovo laptop. The problem does not exist with any other computer working through the KVM switch.
Please note that:
this Laptop on this docking station, at my home, with all wiring and monitors unchanged, has worked for a long time.
I took the laptop off the docking station, went to a meeting, hooked up to a projector, and successfully configured the laptop such that the laptop screen and the projector were displaying the same screen at the meeting.
Then, I brought the laptop back to the same old docking station at my home and tried to regain use of my dual monitors unsuccessfully.
Using Control Panel display, and all sorts of combinations of NVIDIA Control Panel, the 2nd monitor would not be consistently detected by NVIDIA Control Panel. During these attempts, on a few occasions, I had an option to Set Up Multiple Displays in NVIDIA Control Panel; but there was no success in choosing this option. Returning to NVIDIA Control Panel / Displays would not present Set Up Multiple Displays as a valid option (not present or greyed - can't remember). I even went through permutations with the laptop screen open and closed, warm boots, cold boots, searchign for new hardware, etc. Nothing was successful.
Although changing the display within Windows Control Panel / Display was an option, any attempt to extend or replicate the dispay on the second monitor would fail and Windows Control Panel / Display would go back to the single monitor configuration was not successful and effectively ignored by both Windows Control Panel / Display and NVIDIA Control Panel.
You may note the use of past tense. I simply gave up and went to doing productive work on one monitor. After a few weeks, I went back to NVIDIA Control Panel and the second monitor was detected. I was able to Display / Set-up Multiple Displays via NVIDIA Control Panel. Subseaquently, I was able to use Windows Control Panel Display to enable and configure the second monitor and both monitors started working again (without having made any changes to wiring etc).
I don't believe there is any difference in how I used NVIDIA Control Panel on this successful attempt than in any of the earlier failed attempts. There seems to be some sort of a problem with getting the Lenovo to recognize that the second monitor is really there. Please addess this part of the problem as I expect to repeat the process in an upcoming meeting with this laptop.
Thank you for your attention.

Using this xorg.conf file, only my NEC LCD analog monitor could display KDE while the Samsung digital can't.
Any suggestions?

Thanks for your help guys, I'm halfway there.
The second monitor shows the KDE desktop, but it isn't exactly what I expected. Right now, both monitors display at 1024x768 (each) or 2048x768 (total). The larger monitor stretches and distorts the display of 1024x768 to its natural resolution at 1440x900 and it isn't what I wanted. Other than that, the dual desktop setup behaves what I expected to.

Anyone have an idea?
EDIT: Oh snaps. I just did a pacman -Syu and it upgraded Arch Linux to 0.8 and the 2nd monitor stopped working.

Mac Mini Won't Boot with VGA Monitor Connected

I have a new Mac Mini connected to an older VGA monitor using the Apple brand VGA adapter. The mini is fully up to date and runs perfectly when booted. However, if I reboot the mini with the VGA monitor connected, it fails to boot. I just hear the faint chime sound every other second. There is no output to the monitor and the only way I can get it to boot is to disconnect the monitor and then power cycle the mini. I can reconnect the monitor just seconds after powering back on and it finishes booting properly.
Anyone else experience this? It is very frustrating. I've also tested with an HDMI connected monitor (without the VGA adapter) and it boots just fine and the display works properly.
Thanks!

Okay, I'm back with good news: I have found two remedies for the problem which will hopefully solve it for you as well.
Given that the issue only occurs when certain monitors are connected, I concluded that the root of it must be a bug in the Mac's firmware related to DDC (Display Data Channel) handling, and that the most promising way to address it should be to just disable the DDC.
Workaround #1: If your monitor has BNC connectors, use a VGA to BNC cable.
In this configuration the DDC pins are not connected to the monitor at all. This did indeed fix the problem - my Mac mini booted without a problem with the monitor connected. However, I was not completely satisfied with this solution, because VGA to BNC cables are usually quite heavy and inflexible, and do no go together well with Apple's MDP to VGA adapter and the Mini Displayport/Thunderbolt port which has no locking mechanism.
Workaround #2: Remove pin 12 of the VGA plug.
Pin 12 of the VGA plug connects the serial data line of the DDC. Pulling out this pin with a pair of needle nose pliers will effectively disable DDC. I hesitated to do this to my cable (a direct MDP to VGA cable which eliminates the need for a separate adapter dangling from the Mac) and therefore bought a tiny VGA male to female adapter (also called port saver, e.g. Delock 65250) to perform the surgery on that. This has done the trick and my Mac mini has started up fine ever since.
Of course, without DDC the Mac won't know the model name and capabilities of the attached monitor and thus offer some resolution and frequency settings which the monitor may not support, but that's a small drawback compared to having to pull out the monitor cable everytime you turn on or restart your Mac.
