Ubuntu (grub) hangs on a black screen on vga monitor.

I am currently attempting to triple boot a mac mini 3.1 with Windows 7 and Ubuntu 10.04. Currently both Mac and Windows work properly. Refit is installed. When I select Ubuntu on a screen connected to the dvi port everything works fine, however when I unplug that screen and plug a vga screen into the miniport, the refit screen shows up but after selecting ubuntu the screen just goes black. This happens before grub even shows up which leads me to believe it is more of a mac issue than ubuntu.
Thanks in advance for any suggestions.

Hi
Did you try to install the OS using another disk or maybe you could boot the notebook using a Live CD like Linux Live CD or WinPE or PartBE?
Please check this because your issue could be related to faulty notebook part (maybe HDD) or to faulty Recovery disk.
Now its not possible to say what could cause this and therefore you should try booting using other disk.

    There is a problem on my mac mini. I install windows7 in my mac then i cancelled the installation did not finish..after that i saw the black screen on my monitor untill now the monitor is black..

    It maybe trying to boot from the incomplete install.
    Try starting your Mac while holding down the Option key, it should then list all the available boot drives including the Mac OS X one. Boot from the Mac one and then you can wipe the damaged PC one or set the Mac to stay booting in to OS X.

    Apple menu -> System Preferences -> Displays.
    System Preferences can also be found in the Hard drive -> Applications folder.
    Resetting the PRAM can help bring displays back to factory settings if you can't find what you need:

  • Qosmio G30 - black screen on external monitor

    Qosmio G30 (PQG32E) running Vista Home Premium, NVIDIA GeForce Go 7600 driver, 7.15.10.9813
    I cannot get a picture on an external monitor (tried two different monitors). Specifically:
    'Windows Mobility Center' will recognise that a monitor is connected
    'NVIDIA Control Panel - Change Display Configuration' will recognise the external monitor ('Select the displays you would like to use' shows 'Laptop Display + Sony SDM-HS73', which is the plugged-in ext monitor)
    but no matter what configuration I try, using Fn+F5 or Change Display Configuration, I cannot get anything but a (backlit) black screen on the external monitor.
    The monitor is receiving a video signal correctly: when turned off under a laptop-only Fn+F5 setting, it shows a 'no signal' warning, but when turned on again I just get black.
    I have tried changing resolution settings for the external monitor. They exactly match the monitor's native resolution. Still nothing.
    Tried 'Clone' mode and 'Dual View' mode.
    Tried various different orders of switching the laptop and monitor on, plugging and unplugging, etc.
    Have installed latest driver from this Toshiba site (as above). Have NOT tried installing any other driver from the NVIDIA site, since it warns to use Toshiba's - but is that worth a try?
    The laptop's own screen and all other aspects of video are fine.
    It has worked ok in the past (I think before I did the upgrade to Vista, when it was still on XP).
    Do I just wait for another driver update from Toshiba, and perhaps Vista SP1?
    I'm really hoping this is not a hardware issue, since the monitor is recognised etc....

    What port did you use?
    The external monitor (analog) port or the D-video out port?
    As far as I know if you have used the external monitor (analog) port then you should choose the Analog display in the nVidia -> current display
    Then you could use the button FN+F5 to switch between the both displays.

  • Boot camp installation attempt yields black screen, also phantom monitor

    Hey all,
    So... I went to install XP on my early 2008 MacBook Black. I've done it before, so I figured there wouldn't be any problems (I had previously removed it). Only, when I attempted to boot from the CD... it appeared to boot, and I heard the CD drive working, but all I got was a black screen. Not even a blinking cursor. I know the CD is fine as it works in virtual machines. I attempted to use my Vista disc on my MacBook just after this and got the same result: drive access sounds, but a black screen.
    Then I discovered another problem... my Mac has a phantom external display. I almost think that perhaps when I boot off a Windows CD, that perhaps it is trying to use a display which doesn't exist? I won't really be able to test it until I get home (I'm out at college) and can plug in my external display...
    I had an external display hooked up in a previous installation of OS X... I pulled over the settings from that previous installation via time machine after reinstalling. That would certainly explain the phantom display. What is not explained is why I can't get rid of it. I've been trashing the plists that other threads recommend, resetting the PRAM... nothing really works. Detect displays doesn't help either. I'm wondering just what I have to do to get my Mac to realize there is no external monitor. I've read numerous threads on this, all culminating in no avail. Any advice, anyone?

    I tried resetting SMC too... still nothing. I almost think I should try booting from OS X's install CD, and see if the phantom monitor exists there... if it does, then I know there's a hardware problem of some kind. If it's not there, then I should reinstall OS X, and pull stuff over from Time Machine manually instead of automatically this time. I'm guessing that if I pull over user accounts automatically that it will recreate the problem. My only problem with doing stuff manually is that I'll have to jump through a few hoops to get my iTunes library back.

  • Black screen in source monitor

    I am trying to synch a good audio file with my .mov. But when I do exactly what is described here Automatically synchronize audio and video files in Adobe Premiere Pro CC based on audio waves - YouTube I just get a black screen in the source monitor. Why?? Shouldent I be seeing the good sound synched with the video file playing in the source monitor?  I am new to premiere so maybe I have a setting off? Please advise!
    [Please choose a short description for the thread title and only post the actual issue in the main body.]

    Okay, that answered my question. I didnt know the in and out points in the source monitor had to stretch the entire length of the clip when I merge them. But I have another question. As shown in the image, my show is already cut with different takes of the same performance with the reference camera audio. How do I synchronize the good audio for each clip in the timeline?
    When I laso around the first clip in the timeline and the audio (mono 001.wav) underneath it and select Synchronize it moves my clip down the timeline out of place. I want it to stay where it is...

  • Black screen on HD monitor when using DVI cable

    Hi there,
    I've recently purchased a Samsung P2270 monitor with the intention of playing HD content from my mac mini, however, it would appear that this isn't possible.
    Connecting it up with a 18pin DVI-D cable doesn't seem to yield anything on the screen. Wondering if it could be a faulty monitor, I tried the DVI-VGA cable instead and thankfully managed to get something on the screen.
    But being human, i'm still set on trying to get 1920x1080 resolution out of my mac mini!
    Checking the display tab within System Preference, it would appear that the maximum resolution option i have on my mac mini is 1280x800. However, I have an Intel GMA 950 graphics card on board, and it should be able to handle HD ie 1920x1080.
    I've got a grandfather of a mac mini - Intel core duo 1.83 GHz, purchased it in 2007. Running Mac OS 10.4.11 Tiger on it.
    Has anyone any experience hooking up a similar mac mini to a HD display with success? Is there any way around this problem? Or am i doomed to looking at black bars on either side of my display till i upgrade?
    I'd be grateful for any advice/suggestions

    Welcome to  Discussions!
    Looking at the specs of your monitor, I see that the connection is listed as a DVI-I connection. You should try a suitable cable before giving up.

  • Macbook Pro - Black screen and external monitor

    Hi there,
    I'm new here and it would be great if anybody could give me some advice about my Macbook Pro issue. First of all, I would like to thank all the contributors for your comments. I'll go to an Apple Store asap, but I'll really appreciate any of your comments so I'll know more about this issue and how to manage it.
    My device details are:
    Macbook Pro / 2.8 GHz Intel Core i7 / 4GB 1067 MHz DDR3 / Macintosh HD / Mac OS X 10.6.8
    NVIDIA GeForce GT 330M
    Other connected equipment:
    HP Monitor Pavilion 22xi (with an official Apple adapter - projector's plug)
    Wacom tablet Bamboo Fun (USB connection)
    I usually work with graphics software (Illustrator, Photoshop, etc.), since I bought my laptop (3-4 years ago) it has worked faultlessly. But I started to notice some problems about two weeks ago. The problem is basically always the same: After some hours of work, suddenly and randomly (it tends to happen when I click on a button) the screen turns off but the computer is still running (I can hear the fan and hard disk). As I said I use an external monitor, and it also turns off at the same time. That's why I thought it may not be a problem with the screen, it's probably related to the graphics card ?¿?
    The troubleshooting steps that I've tried are:
    After waiting several minutes and without any response, I have to restart my laptop. When it turns on a Panic Report message pops up. It says that a severe problem made me turn the laptop off suddenly (or something like that). The Panic Report says something about "kernel_task", I have no idea what it is, just in case it could help to clarify more (I've printed all these panic reports).
    I also have to mention that this laptop gets really hot on the left side, which I reckon it's a very common thing in these devices. I have to use a desktop electric fan to provide relief to both of us
    I've also disable the "Automatic graphics switching" tab in Energy Saver menu.
    Despite all of this, the screen and the external monitor are still turning off.
    Any idea?
    Thanks a lot,
    Clara

    I would suggest that you run AHT using Using Apple Hardware Test. You can either reboot the machine and press the D key, or use your second Grey disk. This would potentially show you any HW problems.
    Typically these older machines exhibit GPU issues. There is a third-party application called gfxCardStatus, that can provide some insight as well.
    This may or may not help if there are GPU issues - About NVRAM and PRAM (reset NVRAM/PRAM/SMC).
    It is possible to enable remote access (via SSH) and even if the screen is not working, the machine can be accessed remotely. Please see System Preferences -> Sharing.
    Can you run a test with both the lid of the MBP and the external monitor plugged in. Does your external monitor disconnect, but the internal one still show a screen?

  • Dual monitors on the ATI Radeon 9600 XT  black screen on 2nd monitor

    My guess is either a bad cable or bad adapter on the second monitor. Try switching the monitors and see if the problem follows the monitor.

    Aha, all is good.
    I went to Library/ColorSync/Profiles/Displays

    and deleted all SyncMaster.icc files. I did leave behind one SyncMaster file in the home/../Displays which had an old date and I new was ok.
    Rebooted, plugged in SyncMaster, and a new icc file was automatically created in the /Library/../Displays folder.
    My display works normally, now.

  • [solved] Black screen when booting installation

    The basic problem. I have a HD6870, my monitor is connected through DVI (& my second one through HDMI). No integrated graphics.
    After I try to boot the x64_86 version, the screen goes black after 'booting kernel'.
    Things I've tried:
    radeon.modeset=0 (gives drm:radeon_init [radeon]] *ERROR* no UMS suppot in radeon module)
    radeon.modeset=1 (black screen)
    nomodeset (drm:radeon_init [radeon]] *ERROR* no UMS suppot in radeon module)
    disconnected second screen (black screen)
    video=SVIDEO-1:d (black screen)
    i915.modeset=0 (I have no intel, but black screen)
    acpi=off (doesn't work either).
    It is driving me crazy. Can someone help me?
    EDIT:
    Solved by upgrading BIOS

    1 videocard

    Maybe linux does send output to a wrong monitor. Could you try booting with only 1 monitor connected ?
    I initially thought the same, tried with DVI, HDMI single and double monitor, but it didn't work.
    Lone_Wolf wrote:if still black screen with 1 monitor , try a different connection (your card has 4 it seems : hdmi, display port, dvi-d & dvi-i ).
    See above.
    EDIT 2: putting HD in AHCI mode makes just the screen black. Backlight stays on. In Knoppix and Ubuntu it makes the kernel hang at booting kernel _

  • Windows 2008 R2 Failover Cluster - Netapp FAS6280 Black Screen on Restart when in cluster IGROUP

    Hello everyone,
    I've been working on this issue for a month now and have tickets open with Netapp and Microsoft.  We have not been able to resolve the issue as of yet and since I'm losing all my hair I thought I should post it...
    Scenario:
    Two Windows 2008 R2 Enterprise SP Fail-Over Clusters (C1 & C2)
    Two Netapp FAS6280 Filers for SAN storage
    8 DELL R815 servers w/ 2x QLE2562 8GB FC HBAs all paths used (9.1.9.47 - newer did not resolve)
    Netapp DSM 4.0 & SnapManager 6.4.2 (we also tried 1 rev newer, 1 rev older without luck)
    C1 has 2 nodes & C2 has 4 nodes.
    We are trying to add new nodes into the clusters.  We were originally on EMC Clariion arrays and have been migrated to the netapp.  Prior to moving we had 3 nodes in C2 and added node 4.
    Now we want to add 2 more nodes, one to each cluster.  We were able to configure the OS and get everything installed and matching the other nodes.  we can assign HBAs to a test IGROUP and assign a lun, format it use it restart all is well and normal. 
    As soon as we change the HBAs to the IGROUP for C1 or C2's LUNs the servers don't want to restart properly.  They hang at a black screen.  The little green windows start splash screen runs the bar at the bottom.  it then is supposed to fade
    out and come back with the grey screen saying starting windows but that doesn't always happen.  Sometimes it can take 4 hours to restart, or the machine will not come back onine at all.  The pre-existing nodes *do not* experience this issue. 
    They restart in 5-10 minutes without issue.
    We know drivers are part of the issue, but the maddening part is that it all works fine until we try to add the HBAs to the existing cluster storage group.  We have a suggestion to create separate IGROUPs for each cluster node and add all luns to the
    separate igroups.  We configured this on one node and it still restarts long.  We plan to modify the other nodes during our maintenance window and try again.
    On the other cluster we were able to successfully complete the validate wizard and join.  everything fails over and works except the server does not come up upon restart.  If I unplug the HBAs it will come up fine, then I can plug them in and the
    cluster functions.
    Does anyone have any other ideas for us to try?  Currently support for both netapp and Microsoft appear stumped.  Sunday is our Window and we plan to try reconfiguring but I'm losing optimism...
    Thanks for any feedback/ideas!
    -Ryan

    Thanks everyone who looked at this and offered feedback.
    The issue appears to be resolved after the configuration change suggested by Netapp support. 
    The originally recommended configuration for our storage migration was similar to how I've seen storage groups configured on EMC arrays in the past.  1 storage group / igroup with all hbas/initiators for each host in the WFC/SQL cluster added to this
    group.  that group then gets all LUNs assigned to it. 
    The change in configuration that was recommended is to have 1 storage group / igroup for each host and put all initiators/hbas for each host in their own separate group.  Then assign the all LUNs to each of the individual host igroups. 
    There is a lack of documentation on this, but it appears to work.  We had 1 hit for separate igroups but had to go through a couple of support techs to get one to confirm this.
    After applying this configuration in our change window today the issue is resolved.  we were able to fail all resources onto the new node and restart it without issue.  The question remaining for us is why the old systems continued to work while
    the new nodes did not.  The old nodes were originally migrated off an EMC and the version of ONTapp at that time was 8.1.2 and they worked fine.
    We had upgraded to 8.1.3 to resolve an issue with flash cache and it seems like machines that we tried to attach to this igroup after that time did not work.  all drivers software etc the same.  We are wondering if this is somehow related and have
    asked about it.
    I wanted to update this thread, and perhaps it can save someone else some trouble down the line.

  • Adobe AIR apps open to black screen in iOS 8

    Adobe AIR for iOS apps I published using Flash Professional CS6 no longer run properly on iOS 8. They worked fine in iOS 7.
    After opening, they just hang at a black screen (likely the launch screen - I didn't make an image for it).
    Is this a known issue? Are there any solutions?

    I've found an answer- the apps were published using the AIR 3.4 SDK, which I guess iOS 8 doesn't support.
    Republished one with the newest AIR 15 SDK and it works properly.
    Guess I'll have to republish everything.
