Ubuntu :: Computer Will Not Boot After Shutdown (Black Screen)
Sep 1, 2010
I have an 80GB HDD where I installed Windows XP first and then Ubuntu. The thing is that whenever I shut down my computer and then turn it back on (wether it's right away or a few hours later, or the next day), I get the GRUB screen where you have to choose Ubuntu, but after that just a completely black screen. I then have to force a shutdown, then turn it back on, and it works. Whenever I restart it works too, this seems to happen only after a shutdown.
Specs:
Dell Dimension 4600
P4 2.8 GHz procesor
2GB RAM
ATI Radeon x1650 video card
80GB HDD

I have been trying to fix this for some time, on and off, and have been unable to, I have also ben unable to find a solution in the forums.I have installed openSUSE11.2 GNOME on a laptop, the install went fine, and it runs great, except for two problems:When I start up the splash screen doesn't show (this isn't really important, and I am happy to watch as everything is loaded)When I shutdown/reboot the computer freezes and I have to use the power button to switch off.This doesn't happen every time I shutdown, but most of the time.The freeze happens at different points of shutdown, so I don't know where to find what is causing the problem.As I mentioned point 1 is not really important, although I would like to know why this is happening, but problem 2 is very important.

I was messing around with the screen orientation and thought it would be funny to orient it sideways. Big mistake The screen went black.I can force a shutdown, login and I get the same black screen. I tried hooking up an external monitor and the monitor showed no input so I'm guessing my laptop doesn't have that capability with Fedora.This is my main computer.

I had Ubuntu installed on my old laptop in dualboot with windows. This year i bought a new Sony Vaio VPCS12M9E preinstalled with windows 7 pro, but i liked the idea of having the opportunity of chosing between windows and ubuntu, so i downloaded ubuntu 10.10 and burned the ISO-image to a disc, and restarted my laptop just as i did when i installed it on my old laptop. The problem is that when i boot the disc after restarting the computer, the screen just turns black. What can i do to install Ubuntu?

I have recently installed 11.04 natty on Intel Core i3-2100 3.1 GHZ using its own graphic accelerator. When the screen is idle for a long time, more than 1 hour, I get a black screen with the mouse arrow but nothing else. the mouse moves the cursor and Ctl+Alt+F1 does work. How to fix this problem?

I had switched over from Windows to Ubuntu and got rid of windows completely but still had the recovery partition and deleted it. I then tried to add that space to another partition, "Media." For whatever reason it deleted the "Media" partition so I used TestDisk to restore it. I did something wrong and when I rebooted my computer it would not boot so I used my LiveCD to check whats wrong and it had deleted all of my partitions and Ubuntu was nowhere to be found. So I used TestDisk again to recover them, this time it was successful. when I start my computer it does not boot into Ubuntu it just shows a black screen with the white underscore ("_") flashing in the corner. I'm not sure but I don't think it is booting into the correct partition, I think it would be trying to boot the first partition, /dev/sda1, rather than /dev/sda3. If this is the problem how could I fix it? I got all the boot loader information, here it is:

When i use the shutdown-command in the terminal as root, it nearly works. It starts to shut down, and it looks like all programs and the kernels shuts down. I end up with a black screen, sometimes with the ubuntu-logo on, but it never powers off. I have to force it off by holding the power button. When i use the graphical interface to shut it down, it works perfectly. The poweroff-command works without problem too.
Here is the command i use:

I turned on my Acer laptop and during bootup it seemed normal. After it passed the blue Acer logo, all I could see is a black screen and a black cursor outlined in white in the shape of an X. Thinking it would be a one time thing, I turned it off again.it still was a black screen.

Have tried to install 10.04 from a cd sent to me by ubuntu. lts on an x-windows medion pc mt7 (med mt 345). Previously comp. was running windows xp pro. After pressing restart at end of install process I get nothing! Black screen, no mouse control , no keyboard control, nothing at all.
Have tried putting cd in again but get nothing, on pressing restart the cd was politely ejected. Have tried rebooting a few times but get no response. Everything is switched on. So now I cannot even get a terminal up, the only thing I am fairly certain about is that the computer is sending a signal to the screen as there is Not a "no signal" message.

I can't get Ubuntu to reinstall on my computer... I recently reformatted and re-installed windows and I think that might be the problem because I was running Ubuntu 64-bit before I reformatted... Now the problem I am getting is when I go to boot up Ubuntu to finish the install it loads on the purple screen with the Ubuntu logo then goes into a black screen with white letters. Its the screen that tells you to reboot and go into windows a run 'chkdsk /r' and reboot again, the problem is I have followed those directions 3 times and it didn't work, I don't think the operating system really knows what the problem is.

I recently installed Debian squeeze on one of my older pcs. I have had this computer for a long time with windows so I know there is no hardware issue. About half an hour after being turned on in Debian the computer goes to a black screen and the num lock caps lock and scroll lock keys flash.

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.

So I'm in need of VM'ing a couple OS's to keep from repartitioning and dual booting my desktop. The first I'm trying to boot is a 64bit version of windows (have XP and 7 disc, trying XP for now) as I need to convert some of my work's ancient programs that still use DOS functions.
I choose Virtualbox over VMware just for the sake of VB being in the repos. Install and initial config went fine, but when I try to start (run) the VM the screen goes black, then the computer completely stops responding and needs a hard reboot. Pasting what I believe to be the error part in the log. If you need the entire log I can email or host it - too big for a post. Kernel Version - 2.6.32-trunk-amd64. Debian Sid

I've got two laptops running Ubuntu. Both have had Lucid installed from the live cd. I have upgraded one of them to Maverick. Both distributions are running great after they boot up, but I haven't experienced any faster boot times with either distibution. Both boot to Bios and then the screen goes black with a blinking cursor in upper left corner of the screen. The black screen remains for 30 to 45 seconds and then I get the Ubuntu splash screen for maybe 5 seconds, and then desktop. Why am I not seeing faster boot times? I realize 45 to 60 seconds is good compared to other os's, but I anticipated much faster boot times. Shut down on the other hand is quite fast at maybe 5 to 10 seconds. Does anyone else get this black screen on boot? Seems like wasted time cause I can't tell what's going on during the time there is a black screen. This is not a real big deal breaker, as I don't reboot very often, but I just wonder why bootup isn't faster.

Recently I installed vncserver (tigervnc) on my desktop. Ever since my computer refuses to shutdown normally. At shutdown the following message pops up: Quote: System policy prevents stopping the system when other users are logged in Then I have to enter the root password to shutdown. If I stop vncserver before, the computer shuts down normally.

I am using Ubuntu 10.04.1 and I run it 24 hours a day. Recently one morning I went to my laptop and opened the screen but the login screen wouldn't appear. Anytime the cursor appeared, HDD activity would go to 100%. I'm assuming this because the HDD light on my laptop was permanently on. So I made the dumb decision of just holding the power button down and turning it off. When I turned it back on, I noticed it came to a command prompt type screen listing "initramfs" at the bottom apparently wanting me to input a command. I did a lot of research and couldn't find much of anything that would help me. I read about GRUB, superblocks, fsck, e2fsck, etc.. . I tried all of those and nothing has worked so far. Any ideas? I did notice one thing. When I went into the actual install with the livecd, it told me the drive was /dev/sda5, but in Disk Utility on the livecd, it told me it was /dev/sda1

So, the problem is that _sometimes_ (I'd say around 5-10% of the time) when booting ubuntu, right after the splash screen (that pulsing white ubuntu logo on a black background), when normally GDM should pop in, I get a black screen and it stays like that and I have to reboot the machine. This is very annoying because I get this behaviour sometimes 3-4 times in a row... Also, sometimes (maybe half of the times when I get that black screen) the HDD LED on my laptop remains lit and the caps lock LED flashes. Right now I'm using a clean install of ubuntu 9.10, but I had the exact same problem with a 9.04 install and a 9.04 to 9.10 upgrade (so I had 9.04, I had the problem, I then upgraded to 9.10, the problem remained, and then I did a fresh install of 9.10 and the problem is still there).
My hardware is a Asus X51RL laptop, with a dual core CPU, 2GB Ram and a ATI X1100 video board. I also could paste a copy of any log you want me to, to help you identify the problem (but it would probably take some time for me to get that black screen, and also I hope that the logs remain saved after I do a hard reboot).

I'm going through this again. I posted this here as well as in the Mint forums because the architecture is very similar. What happens is that when I reboot, the screen goes black at the steps of the boot after about three seconds with each step. So I see the bios enumeration, then the screen goes black; I see the start up sequence with "Linux Mint" and the green/white dots beneath it, then the screen goes black; then finally, I hear (but don't see) the beep when the password login prompt shows. But if I get into the bios (dealing with the screen going black each time) and change it to "load default settings", then it reboots and works fine. Till the next time I boot.

I followed a tutorial to install XP across my entire HDD. I installed Ubuntu 10.10 "Alongside another OS". Ubuntu loads fine, but when trying to load XP, the boot screen shows up, but then the computer restarts and returns to the GRUB menu.
I saw some threads on this site and tried to type: sudo gedit /boot/grub/menu.lst
In the terminal. It returned a blank text document so I'm not sure if that information was outdated. I then typed: sudo fdisk -l
And got this:
Not sure what any of this means, but I sure hope someone else does. I would say forget XP, but it's hard to let go of some of the games and software I use. I appreciate any responses, thank you.
I tried to format the table as it appeared, but the forum corrected the extra spaces.
