Ubuntu :: Deleted Partition In Boot - Goes To A Black Screen With A Flashing Underscore

Dec 24, 2010

I deleted both the partition with archlinux and the swap in order expand the windows xp partition. I am now unable to boot, just as gparted warned me. When I turn my computer on, it just goes to a black screen with a flashing underscore.

I cannot type anything, but cntrl-alt-dlt does restart. I have been attempting to restore grub and/or windows's boot method for the last 24hrs. The main things I've tried were the instructions here and using super grub disk. However, I have not been successful. I am running an Ubuntu live disk. At the moment, I just want to be able to run windows, but do not have an xp disk because this laptop was issued from my old college.

Ubuntu :: 9.04 Upgrade Fails On Boot - Screen Flashes To Black

May 2, 2009

I have just finished updating my older box from 8.10 to 9.04 and installing a bunch of programs. I had shut it down several times between sessions but when I unplugged it and moved it, it fails. It goes fine through the BIOS and GRUB (I think) but then when there is a screen of text it flashes to black several times and then displays a screen that looks like static with "Ubuntu" barely visible in several places.

Ubuntu :: Partition - Doesn't Boot - Shows A Black Screen With The White Underscore ("_") Flashing In The Corner

Jun 29, 2011

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. The problem now however is that 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?

Ubuntu :: Only Black Screen With Underscore When Booting 10.04

Jan 11, 2011

I just installed Ubuntu 10.04.1 (desktop edition) on my netbook (NB200), the installation worked fine, but when i restart i get a black screen with a blinking underscore on the top left corner. I don't have any options as any key that i press is just printed on the screen. (This happened with every version that I tried so far, even the netbook remixes).

If I don't press anything for some minutes, Ubuntu is finally starting, but without showing the Ubuntu loading screen in the process, like it did when I tried it with the USB.

Ubuntu :: Goes To Black Screen With Underscore In The Upper Left Corner?

Aug 9, 2010

I have a Windows XP Dell laptop that completely froze the other day. I cannot start it up, and cannot even access safe mode -- it just goes to black screen with underscore in the upper left corner.

So, I did some searching and saw a recommendation to create a Ubuntu Live CD to run and access the info on the hard drive, at least. I have most of it backed up, but not the drivers and I know that will be a pain to redo. So, I am mostly hoping at this point to recover a little info off the drive before reinstalling the OS. Of course, if I could just fix it, that would be better...

I get an error message when I try to access the hard drive through Ubuntu that says it is in hibernation mode and I need to start windows and shut it down properly before Ubuntu can mount the drive. Since I can't get into Windows, this is impossible. It also said something about being able to mount it read-only.

Ubuntu :: Screen Loads And Then Flashes Black?

Aug 29, 2010

When I load Ubuntu, it goes to the desktop screen, shows my desktop picture, loads Pidgin which I have set to start on startup, loads Icons, and then the screen goes black. The mouse cursor shows up, I can move it around, and then it goes black again, and the mouse cursor shows up again. This repeats a few times until the cursor freezes. This started happening after I tried fixing a bug with new drivers for my Intel 845gl video card. The instructions I followed are these:

Code:
To use the available fix, run the following commands:
pt-add-repository ppa:glasen/855gm-fix
apt-add-repository ppa:brian-rogers/graphics-fixes
apt-add-repository ppa:glasen/intel-driver
aptitude update
aptitude install linux 855gm-fix-dkms
aptitude dist-upgrade
,taken from here.

I have tried some of the options in recovery mode from GRUB menu, none really work, except booting with default graphic configuration, or something similar like this.

Ubuntu :: Loading Vista From Grub Loader - Black Screen With A Flashing Underscore Character

Jun 29, 2010

I installed Vista on my Acer 64-bit laptop first, then installed Ubuntu 9.10 in a dual-boot configuration. And when I start up my computer, Windows Vista is an option in the Grub menu. But when I use the grub loader to load Vista all I see is a black screen, with a flashing underscore character (it looks a lot like a terminal screen, waiting for input). The screen just stays like this, too - I timed it once, and 13 minutes later it was the same.

Ubuntu Multimedia :: Screen Flashes Black Before Video Play Back With VLC (ATi)?

Aug 2, 2010

I'm experiencing a sudden black flash before video play back with VLC. The whole 3 screens just flash black and come back, and then the video plays fine in VLC. This doesn't happen with other media players, such as mPlayer and Totem.

I'm running an XFX Radeon 5450 (ATi) with the propriety 10.7 drivers. Running 3 17" (1280x1024) in "EyeFinity". I've had a look on the unofficial bug thingy for ati drivers for linux, and there is a bug back from 2008.[URL]...

Just wondering if anyone has any ideas, of tips to start looking to try and solve my little issue, I've spent hours and hours looking though xorg, syslog and other logs in /var/log/ and nothing seems to stand out.

Fedora Installation :: Grub / Try To Boot - Flashes A Quick Blue Screen & Restarts

Jun 26, 2011

I don't really have any Linux experience. But I wanted to try it out. Now I'm afraid I did not set this up properly. Grub gives me 3 options:

Fedora (2.6.38.8-32.fc15.x86_64)
Fedora (2.6.38.8-26.rc1.fc15.x86_64)
Other

When I select <Other> to boot into windows... it starts to try to boot... but then flashes a quick blue screen & restarts. I tried to boot into Window's normal mode, safe mode, and command line... all just restart fdisk -l gives the following:

OpenSUSE Install :: 'x11failsafe' Parameter - GUI Wouldn't Show Up - Ctrl+alt+f2 Yeilded A Black Screen With A Blinking Underscore

Oct 30, 2009

I ran into a problem the moment i installed 11.1. The GUI wouldn't show up (ctrl+alt+f2 yeilded a black screen with a blinking underscore). Failsafe worked fine, though.

So, i tried entering, one by one, every parameter that was entered in the failsafe boot options. Entering 'x11failsafe' gave me a flawless GUI. So, i opened the '/boot/grub/menu.lst' file and added this parameter in the 'showopts' of the normal mode, to make it permanent. Fine. Now, what exactly have i done?

Note- I use an NVidia 8000 series Graphic card. I'll post more details if you need them.

Ubuntu Installation :: Black Screen When Trying To Boot Pc

Jan 28, 2010

Last weekend, I upgraded my old PC and installed Ubuntu 9.10 on a brand new pc. It worked perfectly for 5 days. When I got home tonight, it wouldn't boot and got stuck on a black screen.

[Code]...

I really am a newby here but I think that the blkid command gives me my uuid. The uuid in the /dev/disk/by-uuid directory is in blue so I'm guessing that this is a symbolic link. And then, when I try to create a symbolic link with the ln command, it already exists... But the issue is that the UUID that is referenced in the error displayed is not the same as the UUID in my /dev/disk/by-uuid directory.

Ubuntu Installation :: Screen 'flashes' After Upgrade To Narwhal?

I have a Dell Inspiron 5150 which I first upgraded 'over-the-air' to Narwhal. This completed with no errors. After reboot, the screen momentarily displays some icons before reverting to the background - this loops round every few seconds.I've subsequently tried installing with the CD which runs through with no errors, but does the same thing when it's finished - blink... blink... blink...

Ubuntu Installation :: Black Screen After Second Boot With Updates

Jan 4, 2010

I have an alienware m17 with an Ati graphics card. I was able to log on and install all current updates as well as the card driver update where I was then prompted to restart. Upon doing so, I get the grub loading plus splash screen. My screen then goes blank followed by a noise in my laptop. I have tried nomodeset as well as taking out splash nothing has worked. Also, upon booting up I get lucky if I can get into Recovery mode.

Ubuntu :: Installation Not Completed - Black Screen On Boot

Aug 30, 2010

I have an Acer Aspire One that runs Windows XP. I downloaded both the full Ubuntu (latest version but can't remember the number) and the Ubuntu for netbooks- each on a separate flash drive. I thought I had the netbook version in my Acer when I booted it up, but I saw it was booting the full Ubuntu version. Instead of allowing it to finish installing to run from the flash drive, I stupidly shut it down and removed the flash drive. Ever since then, when I try to boot my Acer, all I get is the black screen of death. I've tried the flashit.exe to flash the BIOS, but no luck. So, I'm guessing it's not a BIOS issue.

Ubuntu Installation :: FGLRX Black Screen At Boot?

Mar 1, 2011

I wouldnt be posting here because I like to solve my problems by myself but I just dont know what else to do. I want to go back to the ubuntu world and I tried Kubuntu. After Installing the Fglrx drivers after a fresh install (10.10 32 bits) through the restricted drivers it shows an ugly font ubuntu loading screen and after that the screen turns "off" (like if there was no signal, the "on/off" light flickers) and it stays like that, but I can use the Ctrl+alt+f1 console. Installing the drivers from ati webiste ends in the same result as before. Downloaded Ubunt 10.10 32 bit and installed it, same results. I have a Radeon HD 3300 integrated. I dont know what to do. The open source drivers works well, but there is no 1280x1024 resolution in the screen manage

Ubuntu :: Won't Boot - Died - Startx The Screen Flashes And Brings Me Back To A Failed To Open Devices Report

Mar 30, 2011

After tweeking some graphics settings, and replacing some hardware, ubuntu won't boot. Being left in the X session (CTRL + ALT + f7), it's what looks like a log:

[Code]....

^ and that's where it hangs. So I went into ctrl alt f1, and logged in with my user/pass, and did the command: startx the screen flashes, and brings me back to a failed to open devices report.

[Code]....

I tried re-installing GDM, but turns out that the PC isn't actually online, hence unable to install GDM after uninstallation. So I downloaded the gdm .deb, and tried to install it from a USB flash drive, but I get dependency errors. I'm at a loss here, I could really use some help, this is the PC that has all my data on it, 450 GB +, I'd love to not have to transfer that over to a new installation!

Debian Installation :: Black Screen On Boot?

Jan 8, 2011

after a couple of years using Debian derivatives, I decided to try debian 5. Seemed to install okay. Installed Mint afterwards (as debian didnt boot) and debian is visible in the boot menu. Upon selection of debian, I just get a black screen and the monitor gives the message "input not supported". I havent had any such problems with numerous distros over the 2 years.

Ubuntu Installation :: Grub Broken + Black Screen On Boot

Jun 15, 2010

PC specs: i7 920, Ati HD5870, 4GB ram Installing Ubuntu 10.04 from a USB stick. The stick is fine as I installed Ubuntu on my laptop with it no problem.

Problem #1: The grub boot manager is missing. The first time I installed Ubuntu it appeared as usual and let me choose between windows 7 and ubuntu. Due to the black screen issues I uninstalled Ubuntu. Since then, every time I've tried reinstalling it I don't get the grub boot manager, instead my PC goes straight to windows. I have formatted the partition I installed Ubuntu on, as well as installing it on another drive, to no effect.

Problem #2: After the Ubuntu splash screen, I'm greeted by a black screen. After a few seconds my monitor goes into standby. Ctrl+alt+f1 does nothing, and removing quiet and splash from the command line didn't help either. I hear I need to use vesa drivers but I have no idea how to go about this when I can't even get the OS to start in the first place.

Ubuntu Installation :: After I Boot Into Setup / It Stays At A Black Screen

Jun 16, 2010

Had Ubuntu installed, it worked fine but I had to format for a new partition (out of space) I program in Windows, I would consider myself a Windows geek, and would like to try out Linux. After I boot into setup, it stays at a black screen. It did that when I was installed Ubuntu, the first time. I don't know how exactly it ended up working, after a lot of different things I was able to get it to boot.
