Ubuntu :: Black Screen After Dual Monitor?

Mar 23, 2010

I have an Intel Corporation Mobile 945GM chipset. As I was playing around, trying to figure out how to get my dual monitor to work. The Mirror Screen was working fine, but then I uncheck the mirror screen option, both my laptop and my secondary monitor black out. I can only see the mouse, and it cans move on both screen.

Here is my xorg.conf:

Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0

OpenSUSE :: Dual Monitor - Nvidia Driver With X Screen - Shows A Black Screen

Feb 5, 2011

I have openSUSE 11.3 with an nvidia card connected with two monitors. In the past I used xinerama which was ok, but now I need to have two separate desktops, one on each screen. I set the nvidia driver with x screen, and now one screen works perfect and the other only shows a black screen. When I move the mouse over the black screen, the mouse pointer turns into an X, but moves correctly, which seems to me that the problem is that I need to set the second desktop to that screen. I looked on forums on how to do so, and no luck.

CentOS 5 Hardware :: Samsung 2343BWX Monitor - Dual Head Black Screen

Nov 30, 2009

I'm a newbie to installing LINUX (was an Oracle DBA for many years) and I am having trouble getting the dual head function to work with my Sony Vaio laptop. I just select a generic LCD with the screen resolution that I want, but when I startx, I briefly get the login window (terminal), then everything goes blank and I have to unplus the samsung monitor and reboot to be able to have a screen again. I have tried the fn + f keys and that doesn't help.

Here is the hardware:
Samsung Syncmaster 2343BWX
Sony Vaio VGN-FJ170
Intel Graphics Mobile 915GM/GMS/910 GML Express graphics controller

I would like to use this laptop as:
Audio streaming from internet (so far not working on my local NPR stations)
Hooked up to KVM switch - using the Samsun monitor and an adesso integrated keyboard
Wireless network (that is working - but it took some doing....)

What files and logs I need to post I will do so, but if what I want to do is just not possible or a big hassle, please just let me know, and I will load windows. Although I really wanted one LINUX box in my home office.

Fedora :: External Monitor Won't Work - Both Monitor And Laptop Screen Black

Aug 7, 2011

I am having problems getting my external monitor to work. When I plug in the monitor, both the laptop screen and the external monitor go black. When I unplug the monitor, the laptop screen works again.
When I startup with the external monitor plugged in, neither screen works or teh computer hangs or something.

I have had the external monitor going on a couple of occasions. I did manage to configure my monitors through System Settings > Display. I turned off the laptop monitor as I just want to use the external. But after rebooting, things didn't work.

I have a Thinkpad E420, Fedora 15

Ubuntu :: Crashing - No Reason Monitor Will Go Black Then On The Screen It Will Be At A Terminal Screen

Nov 30, 2010

I have Ubuntu 10.04 running kernel .26 installed on my Dell Dimension 2350 with 512mb of memory. The problem I have been having is, When I am using the computer mostly Internet stuff for no reason the monitor will go black then on the screen it will be at a terminal screen, kind of like when you start up the computer, I don't remember what is all on it but the last thing in the list was: checking battery state: OK after that the screen will flash in multiple colors and then it goes into a loop of just black screen than a colorful flash and back over to a black screen. the only way I can fix that is by holding down the power button. this will happen mostly on face-book on the games and just on the profile page, but it does happen just checking my gmail or play solitaire it does this around 4-8 times a day.

Ubuntu :: Black Screen - Works On VGA To Monitor But Not On VGA To TV?

Jul 2, 2009

I have this very frustrating problem... I'm trying to build a Linux-based HTPC (Home Theatre PC). I'm running Ubuntu 9.04 Jaunty as the operating system, and it works fine when I have it connected to my 17" Samsung monitor. However, when I connect the HTPC to the TV via VGA I get a black screen after "startx" (I can access the console through recovery mode though). Ubuntu is running gnome, so I guess it's a gnome related problem?

I would have thought it was a problem with the drivers to graphics card, but since it's working on my 17" monitor I've ruled that out. The TVs resolution is 1024x768. What can be causing this? Apperently there's some difference between my monitor and my TV (forgetting the fact that it is indeed a TV, not a monitor), but what? I've previously run Windows on the same hardware without problems, and thought I should give Linux a shot. It doesn't look good...

Ubuntu Installation :: Install To USB - Black Screen - Monitor Is On And Lit - Just Nothing On The Display

Nov 30, 2010

I did a LiveCD to USB install, following the directions I found at [url] When I went to reboot to the USB stick, all I get is a black Screen (monitor is on and lit, just nothing on the display) No cursor or command prompt. I've tried holding shift to bring up the GRUB menu, changing splash quiet to nomodeset, or just adding nomodeset after the splash quiet thing. I've even tried xforcevesa instead of nomodeset still black screen. Looking at the logs nothing is current as of the last time I tried to boot the computer, it's strictly what was written when I installed it to the stick. Other things I've checked/tried, Pressing CTRL+Alt+F1 at GRUB to get TTY, all I get is that blank screen. I've Checked etc/default/grub to ensure the timeout was higher then 0. The Install CD seems to be OK but I have (as it did another install successfully) but I haven't done any throughal checking of it (there was no check this disk on the first screen of the LiveCD) The USB sticks also seem to be ok (in windows though). Using the disk utility on the live CD I did check the file system on the USB stick, the "/" partition came up clean. Anybody have any other thoughts on this install, any thing else I can check?

Debian :: 8.1 Second Monitor Is Detected But Only Showing Black Screen

Jul 30, 2015

I've recently installed Debian v8.1 and installed Nvidia driver 340.46. In nvidia-settings I am able to enable my second monitor and enable it/set it's position..etc. My second monitor is not being detected in Debian Display and is 'on' but only showing a black screen. I've tried researching and implementing various 'fixes', but I'm not having any luck.

I'm running dual GTX 570's with a monitor plugged into one each (DVI). I noticed in my xorg.conf under Section "Screen" I have an option "MultiGPU" "Off"; would this be part of the issue?

I've tried:
- purging all nvidia drivers and re-installing
- installing different versions of nvidia drivers
- add nomodeset in grub

Ubuntu / Apple :: Screen On Display Entirely Black - External Monitor Never Becomes Active

Apr 3, 2011

Just did a fresh install of Natty B1 (previously had alpha 2).. I noticed this issue w/ A2, as well.. plugging in the exterminal monitor (via mini-displayport-to-vga connector) will do the following:

1) turn the screen on the laptop's display entirely black (but not turn it off).. i can move and see the mouse cursor.. but everything on the window appears to not rending or "painted" black..

2) external monitor never becomes active..

the only way to recover is to kill/restart X or reboot after disconnecting the extmon.. having extmon plugged in from boot produces the same results (and it doesn't seem to ever become active during boot up). sometimes this won't happen right away if i plug in the external monitor.. but opening the Monitors system prefs dialog will definitely cause (or detect displays) ,etc I waited to see if the issue would fix itself w/ the beta update, but it hasn't.. Any other 8,1 owners out there that can verify this issue? My (totally uninformed) guess is that it's due to differences in the display/gfx hardware and thunderbolt integration(?)

(I've seen a verification verifications of working-out-of-the-box.. but they were from 8,2 and 8,3 owners (which have discrete graphics cards))... If anyone's gotten this to work with some config stuff, I'd love to see that as well (since the wiki page for 8,1 says it works ootb). If someone could let me know where I should look to capture error output when the above issue occurs, that would be awesome.

Ubuntu Installation :: Black Screen After Updating / Like No Signal Is Coming To Monitor

Jul 13, 2011

I have just "finished" updating my Ubuntu 9.10. (somehow I knew that something is going to go wrong), and now my PC starts, works fine for a few seconds, then I get a black screen for a moment, and then my monitor starts acting like PC is off.Interestingly I think that otherwise everything is working just fine and that I just can't see anything due to the black screen (monitor is flashing like there is no signal coming from PC).

Ubuntu :: 10.04 - Black Screen At Dual Boot With Win7

Jun 13, 2010

I am relatively new to Ubuntu ; I started 6 months ago with 9.10 and it worked fine. Recently I bought from Ubuntu the 10.04 version in French. The installation (dual boot with W7) went well, I personalized the software and had the "brilliant" idea to execute the recommended updates. Restarting the computer I just saw for a couple of seconds the blip up left and then a black screen. Nothing else happened. Posts to the French Ubuntu forum yielded no solution, so I decided to reinstall 10.04 again. It worked well a couple of times, and then again I had the black screen and no boot. How can I delete the installed versions?

Ubuntu :: Computer / Monitor Resolution Mismatch - Huge Black Border On Screen?

Nov 14, 2010

on a 6-7 years old compaq laptop, connected to a brand new hp monitor i am having a mismatch with computer/monitor resolution.

before i had ubuntu 10.04 which could only run in x's safe graphics mode - allowing for full screen resolution but with handicapped graphics - for example videos fullscreen would be quirky and run with cpu at 100%, something which was no problem before 10.04.

then i tried ubuntu 10.10 and later lubuntu 10.10 (which had exactly the same problem); the monitor is running 1440x900 while the computer is rendering to only 1024x768 - leaving a huge black border on right and bottom of screen. the gfx is still crippled; videos fullscreen is quirky as before.

Debian Hardware :: Black Screen Connecting Monitor To Laptop Via Displayport

Apr 19, 2015

I have a laptop and an external monitor connected via displayport. I can configure both displays via settings with correct resolution and arrangement. However, this configuration is not sticking, and every time I shut down the laptop or close the lid I will need to fight with black screens and more to bring the same configuration again. Basically, it seems that the monitor is "stealing" the primary role to the laptop's native screen (I have it configured as secondary, but also being primary the configuration gets messed).

After many trial & errors, this is the routine I have found to make things work every time I boot / awake the system:

1. Boot. Laptop's display shows the booting sequence.
2. When the login screen should appear, laptop's display goes black, monitor shows background.
3. If I press F9 to increase brightness, the brightness icon appears in the monitor, but it is stuck at the minimum.
4. The only way to leave this point is by pressing F7 (project screen) and then F9 again to increase brightness. Then the laptop's screen does light up.

This is when I'm lucky. Sometimes the configuration goes mad and I get mirrored displays and different resolutions, without touching the settings myself. Also, if I unplug the displayport I run the risk of getting stuck with a black screen in the laptop, without any way of recovering the GUI other than rebooting (Ctrl Alt F2 will still show the command line screen).

My system is Debian 8 testing up to date, running in a Lenovo T430 with Intel components. I'm not sure the monitor is relevant here, but in any case it is an Eizo CS240.

Ubuntu Multimedia :: Black Screen On Laptop's External Monitor When Specifying Vesa Driver In Xorg

Jan 16, 2010

I have an Asus z9100 laptop with an Intel 855GM integrated graphics chip, which is running Karmic (the purpose of the laptop is to be a MythTV frontend so my understanding is that it needs to run 9.x in order to connect to the MythTV 0.22 backend - I have installed and configured this using the installable Mythbuntu package) and the laptop is subject to this bug which causes random freezes:

[URL]

So, following advice for similar freezes I've seen, I have added the following options to my grub menu.lst on the kernel line:

nolapic nomodeset

and I have edited xorg.conf so that it makes use of the vesa driver instead of the Intel driver. This results in no freezes and if I wanted to watch Myth on the laptop screen I'd be squared away. However, the laptop has a damaged screen so the point was always to output the signal to an external monitor via its VGA out.

When I attach the external monitor and boot with the setup as described, the external monitor is never detected. But I noticed that if I remove the "nolapic nomodeset" from the kernel boot line, it is detected. However, signal is only output to it during the earliest part of boot (when the Ubuntu logo is in the center of the screen before the full-screen graphic with the animated progress line), after which the external monitor goes black and all the display output goes to the laptop screen. The external monitor power button is still lit up green as if it has been detected and is receiving signal, but it's just a black screen.

get the signal out to the external monitor after the initial part of the boot process, using the vesa driver? Here is the current state of my xorg.conf:

Code:
Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection

Ubuntu :: Maverick (10.10) Dual Monitor- Desktop Bigger Than Screen?

Jan 20, 2011

Im running a wee Aspire One, 1024*600 with an external monitor 1024*768 (maverick desktop edition- 10.10) I have them set up independently, the external is to the right, and above my aspire. I have set this up in the monitors options. But it seems the desktop environment (although not the backgrounds) extend off to the right of my aspire (under the external) and to the left of my external- (above my aspire).

I know that it may be nit-picking, but it is a right pain when I 'loose' stuff on this phantom desktop space. For example- when i move my cursor into one of these spaces- and have to wiggle it about till it pops onto one of the screens. Also- i'd like my screensaver to pop up on both screens, and span them both- not just be repeated on both...

Ubuntu Installation :: Lucid (monitor Switches To Standby) - Screen Goes Black With A Flashing Cursor Then Changes Back To Purple

May 5, 2010

I cannot install Ubuntu 10.04, or even boot into the live CD. I'm not an expert, but I've used Ubuntu for several years, and I'm pretty sure I'm not doing anything stupid... Here's what happens when I boot with the Ubuntu 10.04 live CD: I get a purple screen with just an accessibility(?) symbol at the bottom (this lasts 15 seconds). The screen goes black, with a flashing cursor, then changes back to purple, this time with an Ubuntu logo, with 5 dots acting as a progress indicator (this lasts about 1 minute). The screen switches to standby. The CD drive continues to make noises for another minute or so, then stops.

I physically removed my graphics card (ATI Radeon HD 5770), and plugged the monitor straight into the VGA port on the motherboard. Now the CD boots up fine. I could try installing Ubuntu at this point, while my graphics card is unplugged, and then plug my graphics card back in, and see if it starts working then.

Ubuntu Installation :: Dual Boot With An I8xx Graphics Chip On 10.04 - Get Black Screen Of Death

May 26, 2010

I'm having no end of problems trying to get 10.04 onto my older Toshiba Satellite A50 laptop that I use as a spare laptop round the house. The laptop previously dual booted with XP and Xubuntu fine. I wanted to give Lubuntu a go to see if it's performance was better on this older hardware. When installing I got the black screen of death, and also got the same problem with the Xubuntu CD. Research pointed me in the way of this article: [URL] I was able to boot the Lubuntu Live CD using the instructions outlined in method A.

Once installed however I rebooted and Grub seemed to be knackered. Just sent me to a recovery console of which I had no idea what to do. As I could no longer boot into Windows either I reinstalled Xubuntu 9.10 and all was fine. I decided yesterday to give it another bash this time connecting to my wireless from the live cd hoping it would download an update to fix this problem. Nadda, Grub this time did show and I was able to boot into XP, but upon picking my Linux distro I now get an unrecognised device error with a long string of charachters and then it dumps be back into the grub menu, choosing the recovery mode version does the same thing.

Slackware :: Dual Screen - Disable The Second Monitor When X Is Not Running?

Sep 11, 2010

I would like to use my second monitor with my Slackware (Laptop) setup but they are different sizes/resolutions.

This is no problem with KDE but before X is started and when X ends there are big issues with the TTY0 console being distorted.

Is it possible to disable the second monitor when X is not running?

(Slackware64Current, ATI Mobility Radeon HD3200 card)

I essentially want the second monitor to activate ONLY in the event of an X Session and turn off when X halts.

Ubuntu Multimedia :: Dual Monitor Setup - Separate X Screen Option

Feb 18, 2010

I've played around with a second monitor, but so far I haven't found a satisfying solution. I am using a laptop with a GeForce 9600M GS graphics card. I have managed to set up twinview, but my monitors don't have the same height so I'd rather have something like the "seperate x screen" option. Or how I imagine that option would be like. After some problems with the nvidia configuration tool (I couldn't change the xorg.conf, until I read this: [URL] I now have two separate screens, but the second one is all empty, with black background and X-shaped mouse cursor.

There seems to be no window manager running, I can start programs there with -display :0.1 , but they don't get any frame decoration and, which is worse, no keyboard focus. I'd be fine with a fullscreen konsole there, so I don't really need a window manager, but I do need access from the keyboard. I'd prefer a setup that would allow me to easily (without editing xorg.conf) switch between using both monitors and using only one, because I don't always use the laptop at home.

Ubuntu :: External Monitor As A Main Screen In Dual-output Configuration?

Feb 19, 2010

I'm using dual-screen output with KDE 4.4 on my laptop. Is it possible to have the KDE panel on the external monitor if attached and back on the laptop's LCD panel as soon as the monitor is disconnected?

It seems that Plasma prefers the built-in LCD even if an external monitor is connected. I tried various settings with xrandr and also in the System Settings but none of them helped. The only way to move the KDE panel to the external screen is to disable the built-in LCD.

What I would basically like to do is to use the external monitor as primary in the office and the laptop LCD next to it as a second screen. When I'm traveling I'd like to use only the laptop LCD.

Is there also a nice way to switch between the screens? On the Internet I found a script for the "screen switch" key for IBM Thinkpad and modified it to work on my Dell. But it would be nice to have this also automatic: autodetect the monitor attachment/removal and perform a configured action. The KRandr doesn't seem to have such a feature. Is there anything I could use?

My system is: Kubuntu 9.10 with KDE 4.4 upgrade. Hardware: Dell Inspiron 1545 with Intel GM45 card.

Fedora :: Dual Monitor - Window Maximizes To Full Screen?

Feb 11, 2010

I just rebuilt my fedora box and I'm having some problems getting dual monitors to work. First, I can't reposition my secondary monitor to be on the left. It thinks it's on the right. I can use xrandr to fix this, but that is annoying. Is there no way to do this in the display properties? Second, maximizing a window makes it go across all screens. I unchecked this option in the display properties.I also unchecked the one for letting windows be in multiple monitors at once, but this still happens.

Ubuntu Multimedia :: Dual-monitor Mouse Position Jumps When Moving Off-screen

Nov 4, 2010

I have a dual-screen set-up with Ubuntu 10.10. I have an ATI Mobility Radeon HD 5650 video card. I use my lower-resolution laptop screen on the left and a larger monitor on the right. The monitor is also physically higher than the monitor. See attachment for a screenshot.I have correctly set up my displays so that if the mouse is in the middle of the screen it can move from one screen to the other without jumping. The jumping happens when moving off of one screen in an area where the other screen is not directly next to it (some people call this 'the void').

Example: (See the attachment for a visual example of this.) My mouse is in the external monitor (right monitor). As I move the mouse to the top-left of the monitor (position 1), I by mistake go a little too far and instead of hitting the Ubuntu applications menu, I ended up at the top-right of the laptop monitor (left monitor; position 2). I quickly realize my mistake and move the mouse back to the right monitor, but now the mouse is at the middle-left position (position 3).This same error occurs by moving the mouse on the laptop monitor (left monitor) passed the bottom-right position. This is a big problem when scrolling vertical scroll bars on the laptop monitor (left monitor).I am looking for a fix that if the mouse is at position 1 in the attachment and I move the mouse left, it stays at position 1 and does not go to position 2.
