Ubuntu :: Constant Crashing - Screen Will Go Black And Then It Will Start Flashing Like White Bars
Dec 20, 2010
My computer keeps having some kind of meltdown. i really cant explain it other than the screen will go black, and then it will start flashing like white bars, or different colored bars. this happens at such random times i cant exactly pinpoint what sets it off.
the only thing i may have a clue to is that in my update manager, there is one thing that is a distribution update that i cant check to have it installed or anything like that. its then "Gij" and its description is it is "the gnu java bytecode interpreter" i just dont know if i should just go back to an earlier form of ubuntu because these problems didnt start happening until i upgraded to the new ubuntu

I get past the count down. The bars run across the top. Then my lcd monitor announces it has no signal and goes to sleep. Had this problem with earlier versions of Ubuntu, particularly 8.04. Was fixed in 8.10.
get Fedora 11 up and running?

i thought i would give ubuntu 10.04 a try. So i downloaded the iso twice from two differant sources and burned to 2 diff dvd with diff burners and get the same problem. When i boot off of the disk i get the menu but whether i choose install are run live cd it just sits there for a sec are 2 then goes to black screen with flashing white bar in upper left hand corner and thats all it does. even tried my 9.10 disc which i know works. but it does the exact same. I have purchased a new video card since i last ran ubuntu and its the nvidia gtx 260 core 216. would that be whats causing my problems?

I have re-installed Fedora 3 times, each time, after a little while of use, when I am botting it up, it loads up, and before the login screen appears, the screen just goes black, and I end up with just a black screen and a white line in the top left corner flashing, thus resulting in me not being able to log in. The exact same has happened a number of time
Could it be something I had installed? Also, whilst using it, on the third install, a few times a message appeared telling me there was a kernel error, could this be linked to the problem? I was running Fedora in GNOME, but I had KDE installed too.

I have a fresh install of 11.04 on my ThinkPad, and it is crashing to a black & white text screen unpredictably. I was able to find the following in the syslog, which looks similar to what I see when it crashes:

this is my first time doing a custom partition, I tried to do it with only the assistance of reading as I go, but I don't believe I found enough information last night. What I am trying to do, is put openSUSE on 200gb out of 500gb space on my external hard drive, as well as on 50gb space out of 110gb on my internal hard drive. The remaining 60gb space on my internal drive is going to be for microsoft windows. The remaining 300gb space on my external drive will be storage space. It seems like what I want to do is achievable
What I want is to have my main openSUSE on the external drive (primary partition I think?), with the GRUB loader so that when the external drive is not plugged in, my little brother can use windows on my internal hard drive. I tried this last night, and when installation had finished, I rebooted my computer and the screen was just blank black with the flashing white line as if waiting for me to type, although it would not allow me to type when I tried. It would be great if someone could tell me the order in which to partition, including the terms primary partition, extended partition, and logical partition, as needed.. I don't want to permanently muck up this machine.

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?

I recently wiped and partitioned my hard drive on my Sony Vaio Z series laptop. I set up the NTFS partition for windows, the Ext-4 partition for Ubuntu 10.04 Netbook Remix, and a large NTFS partition for my all my media. I installed the netbook remix off of a flash drive, and I couldn't have asked for a smoother install. Everything went fine, and I proceeding to install google chrome and all the other little goodies. After that, I configured all my settings and ran the update manager to get everything just fine. After a reboot, I became frustrated and prevented maximus from running on start up because I did not want every windows I opened to be maximized. After a reboot, the screen would flash very brightly more than once per second. I could see the top bar with the processes and such as well as the correct background, but I cannot do anything because the screen will not stop flashing. I figured out I could stop it from flashing by pressing ctrl+alt+F7, but the screen just freezes where it is at and is still unusable. Desperate to start enjoying my Ubuntu Netbook Remix, I wiped the Ubuntu partition and reinstalled and did everything EXACTLY the same except instead of preventing maximus from opening, I used gconf-editor to change the setting to not maximize everything by default. Reboot, exact same problem.
I've searched everywhere for a solution, but I only find people with vague similarities or explanations. Could it possibly be a graphics problem? My laptop has 2 graphics cards in it - an Intel integrated one and an nVidia one. The nVidia one has a hardware issue so I just use the Intel one for now. It is also worth noting that I have installed Ubuntu 10.04 (desktop) on my machine before and I never had any such problem.
Also, I tried booting up in the "safe mode" equivalent, but I eventually encounter a black screen and I am forced to hold down the power button to shut it down.
(also, if it's worth anything, I know how to use windows well if there's any way I can change something in Ubuntu from my windows installation)

I prefer ubuntu (which I have been meaning to install for a while) but my netbook currently has linpus lite on it. (It's an acer aspire one). One night I left the netbook sitting open (forgot to close it), and when I went to use it the next day, when I started it up, the desktop did not show the normal icons in the background. It still showed the bar at the bottom with the connection icon, power icon, etc. as well as the "Internet" search bar in the top right corner.
But instead of the usual linpus desktop icons, there are just black and white horizontal bars, with some coloured dots in the black bars. I can still use the terminal to open firefox, and presumably other programs. It still connects to wifi signals, and the bottom bar looks normal and functional. I am posting this message right now with my netbook, and it doesn't seem to have lost any functionality. I would much rather just click on things most of the time instead of opening terminal for everything.

After being on the computer for awhile, it suddenly stops and goes to the purple screen like one would see when turning the computer on, only slightly distorted. after a few moments it switches to a black screen with a flashing _ but you can't type anything, and then it changes so it's blank, and these white bars start to flash on the screen. I just put 10.04 on my computer about two days ago, it's been doing it since. When I first tried to upgrade from 9.10 I encountered a huge error of some sort so I just put a brand new install onto the computer from CD.

i've installed 11.04 on an intel classmate nl1 netbook (atom n270, gma950 graphics, 1gb ram) but have a problem with flash when i visit a specific website. i don't have any other general problems with flash. e.g. videos works perfectly. the problem is a white box flashing on the flashplayer screen. i installed adobe flash 10.3.181.5 and have tried flashaid. if i select low quality in flashplayer then the problem is much less, but it doesn't go completely. i never had this problem before with windows xp when visiting this site on the same netbook.
i asked the website customer services and this was their reply! "no we have not tested the program on ubuntu personally i have never heard of it before. our it suggested downloading google chrome and using that as your internet browser as that is the recommended browser." changing the browser makes no difference. i tested firefox, seamonkey and chrome. could there be some driver issue with the graphics card?

I am having some issues with my screen resolution. I am not sure if it is a monitor or graphics card issue. I believe I have the ATI x300 card. I am gunning a dell dimension E510. My monitor is a MAG Innovision. The screen resolution keeps changing. I had this same issue with 11.3. Also, the screen looks fuzzy in certain places, especially white areas and bars at the tops and bottoms of pages. By fuzzy, I mean it will be a color that doesn't belong there and it will kind of look like static, in either a line, or a blob, or just the whole box. I recently had to disable all desktop effects because they would make the screen unusable.

Once I installed it I've been having a problem where the screen flashes black for a split second. i looked up the problem and found this:I navigated to the directory it said, but I don't have an "options" file. What should I do? Are there any other fixes for this? It's quite an irritating problem.

When I try and install Ubuntu 9.10 it gets to the flashing Ubuntu logo, then the screen just goes black. It then says: (initramfs) Unable to find a medium containing a live file system. I also tried the disk on a another computer and it worked fine, and I've installed Ubuntu 7.10 on this computer before without a problem.

I'm using debian for the first time and I recently downloaded the Debian Lenny 201 Live CD to test it on my old computer (I'm planning to use Debian 5.0.4). It has a Pentium III (550 MHz) processor, 192 MB RAM, 8 MB graphics memory, 20 GB HDD with a monitor supporting 1024x768 resolution. The problem is, after the booting is complete a blank flashing screen appears with a cross-shaped cursor in the middle. I continues and nothing happens. I tried with solutions like editing the entries with 'live xdriver=fbdev', 'live xdriver=none', and 'live vga=771'.

so I installed fedora 12 last night, everything was fine. Installed some things, moved music over, etc. (Dual booting with windows vista btw) So I install my graphics card driver, (ATI Radeon HD 3200) and I reboot. When I open the bootloader (I think thats what it is), It starts to boot, then just has a black screen with the flashing underscore. I can type and stuff but nothing happens.

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.

I have just recently installed Linux Lime along with windows 7 Home Premium. Before, there would be a menu asking me which operating system I would like to use. When I click linux it goes to linux and windows 7 goes to windows 7. Now when I click Linux, the black screen you get at the beginning shows a - (dash) constantly flashing on a black screen and won't boot to linux. This is normal as it does that for a second then boots. Now its stuck on that flashing dash on a black screen and won't boot.

I've installed Fedora 12 from usb to my laptop. But, on start up a b&w grub screen occurs. (I think there is where we chose the kernel for booting?)
When I start the the system from usb ordinary multi-boot screen comes and let me choose which operating system that i would like to start.
Do i have to start from usb all the time?

I'm a little new to ubuntu. I installed a video driver and after restarting I got as far as the login screen where I saw that the driver did not work: screen is mostly black with random bars of color. I was only able to restart in recovery mode mode. I tried the fix graphics option, which did not work and also some commands that I've seen posted in other threads. So far, still cannot delete the problematic driver or boot up normally successfully.

i've got a mythbuntu 10.10 box connected to my tv; sometimes i want to use it to watch internet tv. owever, when i try to resize videos to full-screen, sometimes black bars intermittently flash across the entire screen. this does not happen when the video is in a window or on the web page, only when going into full-screen mode. unfortunately, on some of these sites, even the "large" in-page video selection is still too small to be comfortably watched from the couch.
i'd suspect it's something with flash, but a similar thing happens when i'm using skype inside a windows xp on vmware. black bars flashing across when in "full-screen" but just fine when zoomed up inside a window. and i don't think vmware video output is flash-based. so it may be something else entirely.
also, this doesn't happen on all internet video - i've only had it happen on video from nbc.com and nfl.com (i haven't really had the opportunity or reason to try many other sites yet), and it was only a little noticeable from the nfl.com but nearly unwatchable from nbc. yet if i go to videos, i have no trouble getting any of their videos running full-screen.
i have an integrated geforce 8200 graphics, and i'm running the nvidia proprietary drivers version 256. i'm not running 260 since its vdpau capability is questionable, and i need that for mythtv. i have a 64-bit system.
does anyone have any ideas regarding this? the fact that i'm getting consistently good results from videos yet consistently bad ones from the tv networks makes me wonder if it's something i'm even going to be able to fix.

As the topic says. I'm having problem after problem, everytime I figure out a way to take a step forward, my PC has pre-emptively taken a step back.
I'm unable to boot to X or (recovery mode).
I did try booting to a LiveUSB in order to run update-grub, but then it occured I have no idea how to do this from a LiveUSB that will affect the internal HDD installation?
So I'm currently trying to reboot from Live USB, but that just seems to have locked up the PC on the white ubuntu logo. I'm afraid to hard reset it (been doing too much of that lately). How long should a Live USB take to shutdown? (been about 10 minutes so far ). It's not a persistent LiveUSB as far as I know, and I basically just booted to the desktop and then start the reboot cycle as soon as I realised I didn't know what I wanted to do .
