Swapped Monitors now I have no display

Today I was trying to configure my system to display on 3 monitors all using differing outputs: DVI, VGA, HDMI which were on my video card. It seems that the card can only render two monitors at a time. But the bigger problem now is that something went wrong... (No i don't know what happened) it will only render on one of those three monitors (DVI) after starting X and I have no idea why or how to make it load on the other two (even when only connected to one of them). When I try starting x on either just the HDMI monitor or the VGA monitor I simply get a blanks screen. I don't even know where to start. Any hints?
Also, this computer has loaded onto all of these monitors in the past, so it must be some configuration issue.
EDIT: This actually only seems to affect using the HDMI in conjunction with the DVI or VGA. I can run VGA and DVI together but cannot run either of them with HDMI or even HDMI by itself at this point...

if or when you have the right driver;
you have a monitor to look at it seems depending on your wm/de there should be a tool to turn them on maybe there just off and its after x so its a x config i would think.
try xrandr
xrandr --output VGA-1 --mode 1920x1080 --pos 0x0 --rotate normal --output HDMI-1 --mode 1920x1080 --pos 1920x0 --rotate normal --output DVI-1 --mode 1920x1080 --pos 3840x0 --rotate normal
thats from left to right. your output's may differ as well as resolutions and position depending on your setup. arandr is a good front end to xrandr its in gtk though so it will pull gtk and dependencies if you do not have it.
That would certainly make sense, the monitor only goes blank after the x has started... I'm using Awesome as my WM... Thanks for the tip!

  • I did the latest update on my iphone and now I have a displayed white usb cord with an arrow pointing to ITunes with the circle with the musical note inside.  I can't turn off the phone nor can I get beyond this display.  Phone goes to voice mail..no ring

    I installed the latest update to my iphone 4 and now all I have is a display of the white usb cord with arrow pointing to ITunes with a clue circle with the musical note in it displayed.  I can't access my phone at all.  I tried calling it and it says unavailable.  I don't know how to restore it...it says it is in recovery mode but when I try to recover, it says no iphone found.
    I have no idea how what to do to restore my phone.  It's fully charged.
    GRRRR

    Put the device in DFU mode (Google it) and restore.

  • Photoshop CS6 goes crazy on my second monitor now I have updated to Mavericks

    I've had a look around to see if anyone if having the same issues but haven't come across anything to help yet.
    When I updated to mavericks my java installation disappeared & so Dreamweaver wouldn't work. Now I've installed jdk-7u51-macosx-x64.dmg & it's working again.
    However now I'm seeing an issue with Photoshop CS6 when I drag it across to my second monitor- see image below
    The only way I've found to get rid of this weirdness is to drag the screen back to the primary screen and wait for it to settle. Dragging the screen in itself is really laggy & I can sometimes manage to get it to appear normally on my second screen if I wait a bit or wiggle it around. But this time I can't even get the window to appear on my screen at all. It's as if the programme isn't open any more. But if I select 'show windows' I can see it is still open & still flashing with the mess shown in the image below.
    Really quite frustrated with Apple about this, now I can't brag as much about how amazing macs are compared to PCs!!
    Help?!?

    The Mavericks Mac I'm writing on still has CS6 on it so I'll see if it happens to me when I'm near my desktop monitor.
    Well, I just tried moving the Photoshop CS6 window around between two monitors in Mavericks and didn't get the same problem, so I really don't know what the problem is. But you could try asking at the actual Photoshop user forum since they'll know better questions to ask than we would in this forum.

  • Connecting an external display and now I have 5 displays

    I have two Macbook Pros running OS X Mavericks. They are both connected to an external display. One works fine but the other one is not working correctly. When I try to connect to my external display I see 5 displays. When I deselect the Mirror Displays button I have to mess around with the order to find my Macbook display and my ViewSonic display so they can be side by side. What are these other virtual displays? And how do I disable them?

    According to this:
    http://docs.info.apple.com/article.html?artnum=86286
    you need to keep the laptop plugged into AC power when operating with the lid closed.

  • Have to display a dynamic table on specific height of JSP page

    I have large data.
    I have to show this data in dynamic table on jsp page.
    the JSP page is logically divided in different pages (as this page is used for printing on specified size of page)
    I can only display atmost 12 single rows on one page
    but some times text of one column of row become so large that rows expands vertically and occupies space of 2 or 3 rows (thats why now i have to display 8 or 9 rows on first page and then remaining on next )
    becoz of this i cant implement this check (only show 12 rows on a page).
    so what can i do to show specified height of table on one page and remaining move to next page.

    hi,

    The Problem is "iSTORE in India Doesn't Helping me in this issue".
    I would request APPLE please get this FIX as I am also your customer and now it is globalization.
    SO please find any way to get this fixed...

    Thanks
    APPLE user
    sonu.mas007

    They can provide some kind of way towards this solutions...
    eg:
    1) Accept my UK iPhone in India courier it to Purchased Place (Repaired it)
    2) Accept my UK iPhone in India Take some difference assign me India iPhone.
    3) Accept my UK iPhone in India give me any option to ugreade to iPhone 5 (Indian).
    4) Accept my UK iPhone in India give me some Receipt (Courier me My new iPhone from UK).
    5) Approve my VISA for going to UK again as it not easy for INDIAN to go there with some kind of this Reason.
    6) Give the Postal Address where we can send our APPLE to get only Service and they can send it back to us if it got reparied.
    As no one would like to go UK only to Purchase APPLE..
    There are some personal reason they have to go to Other countries for ... and If some one is FAN of APPLE like me would do the same mistake that I have done..
    7) If the APPLE wanted to serve their customer they would have get to the solutions with their excellent mind.
         As far as I am concern I am just the USER of my FAV APPLE but.. .. I guess this policy would not keep me as the SAME FAN of APPLE as I am now...
    If this is not going to get solved I guess I have to start with other BRAND Like SAMSUNG S4 where I can get everything in my STATE..
    But YEH it not a right was to have this BAD policy.
    I just dont know why they are not coming ip with great solution for this issue in this tecnology world.
    Any help to find other BEST Brand who has awesome services..
