Ubuntu :: Screen Keeps Going Blank/flashing Blank?
May 17, 2010
When i use my computer (whether it's going online, typing, playing a flash game, or coding) I get these "Black Flashes" that are becoming longer and more frequent. A "Black Flash" is when my computer screen turns blank (but you can still see the backlight) and i have to press the NUMpad ENTER button, shake my mouse furiously, or click my mouse, which sometimes causes undesired actions, but gets me my screen back. sometimes the Black Flashes last a milisecond or 5 seconds or i have to hold the power button and restart because it won't come back on.
Specs:
Toshiba P205-S6337 Laptop
Ubuntu Karmic Koala
2.39 GB of RAM

Running 10.04 as the only OS on a HP desktop - been running fine for months. Did an update - probably hadn't done one for a couple of months - may be a red herring. The system appeared to crash while inactive. Trying to boot - I get the Ubuntu 10.04 screen for a short while then it goes to blank screen with a flashing cursor at the top - occasionally it will give me an error that /home is not ready - skip or manual fix. I have sda1 = ext4 root
sda2 = swap
sda3 = ext4 home
sdb1 = ntfs
I removed sdb1 from fstab as initially it was complaining about this drive not being ready. The error switched to complaining about /home. I am able to mount both of those filesystems with no problem manually. I ran mke3fs on /home (I forgot the -n parameter! but no problem as I have good backups) - same error - complains about /home not being available at boot even though I can always manually mount it from live cd or manual recovery. I can rebuild this system - and I may as it was upgraded from 9.10 - I may do a fresh 10.04, but I would like to fix the boot problem in case something like this happens again when I actually care about fixing it.I recreated the grub2 configs - I don't have the command to hand, something like: sudo update-grub --root-directory=/mnt/boot/grub /dev/sda

I've just installed ubuntu 9.10 from a live cd on to a 2nd HDD, with vista on the 1st. When I turn my PC on GRUB comes up and I can select ubuntu or vista, vista works but when I try to boot ubuntu the screen goes black with a small flashing underscore in the top left and then just goes completely black, nothing else happens after this. I've tried reinstalling from the live cd but when I go install nothing happens and the screen goes black again. When I was installing I changed the boot to something like scsi?
My PC's specs are:
Dell inspiron 531
HDD1: Ubuntu(300GB)
HDD2: Vista(1TB)
OS
Windows vista
Graphics card.
ATI radeon HD 4700 series

I recently installed Ubuntu 10.04 on my Aspire One netbook, but everytime while booting, I am stuck at a blank screen with a blinking cursor. I've tried reinstalling but to no help. I've also tried installing 9.10, which will boot, then upgrading to 10.04 which then produces the same problem.

I have a desktop with AMD Sempron 3000+, 1.2GB RAM, VIA S3G Unichrome Pro IGP, VIA SATA RAID controller based disks, PS/2 mouse and keyboard running Windows XP. Wanted to move to years ago favourite (linux based systems), I downloaded Ubuntu 10.04 for i386 and am trying to install both using CD as well as USB. After the Ubuntu start-up menu for installation, I select install Ubuntu option, turn off 'quiet' so that I can see what happens. The screen goes blank dark with a flashing cursor at the top.
In the kernel messages, the see that it has detected the processor, set the clock, assigned the PS/2 keyboard to input3 and then says:
[1.911624] isapnp: no plug and play device found
After this, the system hangs. Keyboard doesn't work.

I'm using "sudo rtcwake -m disk -s 5000" or whatever the seconds is for the time I need it. It doesn't help if I use mem. Anyone know what's up or know a better program?

Slack 13.0 X sometimes fails to start after boot about 50% of the time. linux says "starting X11 session" then I get a blank screen with a flashing cursor and absolutely nothing else. I can <ctrl>-<alt>-<F7> and get a text prompt, log in, and startx from a command prompt. After that, I can reboot once or twice and still get a graphic login, but will soon revert to the dumped condition. I have reinstalled X and KDE twice now as well as deleting my .kde folder. This condition started when I inadvertently ran out of disk space on my /home drive. Since then I have migrated /home to a larger drive and watch it's disk space very carefully.

I have just updated to 10.04 on my Dell Insperon 8200 laptop, and all seems well with Linux.My problem is that although it shows in Grub Windows XP will not load. I just get a blank screen with a flashing cursor.I have tried to grub-mkconfig and grub-update, both of which reported successful results.However on reboot I still get a blank screen for windows.This was not an issue with 9.04 and 9.10.so I don't think it is the machine.

I installed Win7 after Ubuntu (10.10). I attempted to reload grub so that I would be able to run them dual boot and now I can't load anything.
I followed the guide here: [url] and went threw it a couple of times now to make sure it wasn't user error.
I am using a live cd from 10.04 because it's the only one I have. Any chance that's why it isn't working properly? I wouldn't think so, but I assume that it's possible.
If that is the case; Any way to solve it without using the live cd? I cannot burn a new disk because I have to boot from disk to use my computer right now.
I just get a flashing cursor on a blank screen when I try to load.

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 am having the same problem, as soon as X tries to load my screen just goes blank. I have an ATI Radeon 9550. At first I tried switching between VGA and DVI as well but upon ruling that out, I switch to my on-board video card and that is working thus far, but I'm trying very hard to figure out a way to be able to switch back. Anyways I'll check back in later on if I have any new information I will post.

1. Installed Ubuntu 11.04 32 bit for my 64 bit laptop to run alongside windows 7.
2. Installation worked, but had problems booting - it booted sometimes from the grub menu other times didn't
3. Found no solutions for problem so deleted grub and removed the ubuntu OS from disk management.
Since that time I've been attempting to install the long term support (version 10.04) for a while and nothing's happening. The button to "install" or "try without install" leads me to the ubuntu logo screen with the dots flashing under then a blank screen. The memory stick's light doesn't flash either hence it's not working. I've tried the 32 bit and 64 bit version, downloaded from multiple sources and converted the iso using multiple programs.
I then tried the 11.04 version again in 64 bit but that didn't work so I tried what I did in the beginning, the 32 bit version and it works. It feels a bit like after the first install my laptop only wants to install the 32bit 11.04 version and is a bit racist (can i say that?) to the other versions so completely rejects them. Why?
Is there any chance if I try to use a cd to boot that version and it may work from there?
And if I can't run 10.04 for some weird reason technical or w.e, can someone reccommend me another REALLY good version for a beginner which is easy to install and doesn't have too many problems.

Is there a known problem with the Lubuntu 10.10 image here? I have downloaded it to two different computers, then burned the images to two different blank CD's (different brands) and neither loads. Both only get as far as the Lubuntu menu, once ENTER is pressed at that point to load the LiveCD, a blank screen eventually appears with a flashing cursor at the upper left of the screen, that's it. They were both burned using the slowest burn speeds available.

The day started as usual until I got the very bright idea to install Ubuntu. A new OS along side W7, that sounded great. I checked some guides on the Internet, it was all very straight forward. Install it and Grub will show you the OS:es when you boot up. I installed Ubuntu, rebooted. After the BIOS messages the screen goes blank and my screen on-button begins to blink, as if trying to find a signal, I press enter, it reboots instantly. After BIOS messages I get to a screen that says "GRUB error: uknown filesystem grub rescue>"
I've looked through everything here and nothing works. I've tried to fix the mbr-thingy using Windows Repair and even though it says "one partition was updated with new boot-thingy" when I reboot, I get into that very same grub rescue. I think my setup has something to do with it. I run RAID0 (2x360Gb hard drives), first having C: at 50Gb and then the rest as F: for programs and such. What I did was that I shrunk the F: part and then used that as partition for Ubuntu. Also please have a look at these screenshots, my partitiontables and such seems completely wacky to the raid: Where should the boot-loader go? I'm very, very new at this. I've had Ubuntu Netbook remix on my netbook for a time but still treat me as an utter beginner.

I fixed this issue on 10.04, but just recently (1 hour ago) upgraded to 10.10 and am having the same issue. Machine boots fine, but the screen is blank for most of the boot, and plymouth is up for about a half second before I get to the login screen.I've tried searching the threads, but for the life of me I can't find the solution and can't remember what I did to fix it on Lucid.

like any other Linux newb, I came to Ubuntu because my Windows crashed one time too many. And I chose Ubuntu because "it just works". But these past few days that hasn't been true. I'm posting this from a netbook with Ubuntu, and am having no problems whatsoever, but normally I use an Acer Aspire 5920G laptop. I'll include the specs as written on the sticker:
* Intel Core 2 Duo processor T5250 (1.5GHz etc)
* Up to 1024 MB Nvidia Geforce 8600M GS Turbocache
* 2 GB DDR2
Let me know if you need more details, and I'll add them later. Now, what happened was I clicked "hibernate" while leaving Firefox open. (I've done this hundreds of times, no problem) And when I went to turn it back on the next day there were weird graphical glitches in the loading screen, and it booted to the "tty1" prompt screen. I did a lot of googling and found quite a few posts about it, but the solutions either didn't work, or I didn't understand them. After trying several different suggestions from this forum and others, I managed to delete the graphics drivers. That enabled me to boot in low graphics mode, and naturally, I tried a whole bunch of things to make it work properly again. That only made it worse. Now it went straight from the loading screen to just blanking out and turning the display off. So, I tried new things. Over and over. The weird thing is even when I disconnected my harddrive and ran from a Live USB, the problem persisted. Could there be an issue with the graphics card itself? Anyway, after reconnecting the harddrive I tried to boot again. And it suddenly worked. Even HDMI to my bigger screen worked.

I have been running 10.04 quite successfully, when I upgraded to 10.10, I have a problem with the newer kernels. If I let it boot into the latest one 2.6.35-23, I get the Ubuntu 10.10 splash screen for a second then a blank screen, same with 2.6.35-22. I have to run with 32-25 to get it to load the gui.
I have an AMD Sempron 2800, 1.6GHz pc, but I'm not sure if it's running 64bit.

I've been running Ubuntu 10.10 very smoothly for a while now. Decided to upgrade to 11.04 - managed to corrupt the hard disk the first time by letting the laptop hibernate part of the way through but reinstalled from a live CD of 11.04 and it's now working except for this issue.
If I shut the screen on my laptop (or press the screen off button) either the screen won't come back on or it will but frozen (I can move the mouse but not click on anything etc.) In this state music continues to play (from spotify under wine) and if I press my hibernate shortcut (power button) the computer hibernates, only to wake into the same situation. I've got a Dell Latitude D520, upgraded to a bigger hard disk and more ram - the ubuntu partition has 50gb. Windows is working fine.
Edit: I noticed a sticky thread which includes something about a blank screen but I think this is a different issue?

My problem is that I can't log in to Ubuntu, as you've already seen in the title. Here's what's happening:
I turn on the computer. I see the GRUB. I press Enter. I see a blinking underscore (_) as if i was in a terminal. The underscore disappears and I can see my cursor, but nothing else. I can move the cursor, but that's all I can do.
I've seen some similar problem here on the forums, but he could log in, he just couldn't see the screen.roblem!

The PC boots up normally into Gnome desktop environment. When I hit ctl-alt-[F1-F6], -The screens blank out. One screen gets no video signal, as evidenced by a blinking power light The other screen is completely blank (not even a blinking cursor) If I hit ctl-alt-F7, I get the Gnome desktop back. I have been able to determine that even if the screen is blank, and appears completely dead, the system processes my keystrokes. For example, if I pretend that I am at the log-in screen and type <username> <enter>, then <password><enter>, then 'xinit -fg white -bg blue -- :1 vt8'<enter>, the PC switches to virtual terminal 8, and shows a shell window. From that point onwards, my keyboard entries show up in white-on-blue characters, and the behavior of this shell window is perfectly normal. I can log into another Linux box using ssh, start a Gnome / KDE / XFCE4 / LXDE session and work on the machine normally; or start another X-session and a desktop environment of my choice. My guess is, the console is invoked perfectly well; it is set to display black-on-black characters.
What I Am Looking For:Confirm if my guess about black-on-black console is valid.
Suggest how I could get a screen showing white characters on black (or indeed, any combination I could read)

I've recently installed the 64bit version of WUBI on ASUS K50IJ with windows 7. Everything went smooth however when I try to boot into ubuntu, it shows that all the drivers are loading, I can even see the desktop background image for a second and then the screen goes blank. It is still ON however nothing is showing on it.
Pressing "CTRL+ALT+DEL" reboot the system.
even get access to the console for further debugging?

Anyway one day I start my computer and instead of starting normally it comes up with a screen which says GNU GRUB version 1.97~beta at the top. I selected the option Ubuntu, Linux 2.6.31-19-generic as I figured this is what normally loads without being prompted in the grub menu, but after this I got the ubuntu logo for a few seconds then my screen goes blank. My laptop is a hp510.

I'm a newbie so apologies if there is a trivial answer to this.
I (maybe somewhat rashly) tried to connect my tv to my laptop (Dell Latitude D400) running Ubuntu 9.10.
I plugged in the cable, went to the System>Display menu, where it had detected the model and make of tv (Samsung 19" LCD) (I think the resolution was 1650 x 1050 or similar). I clicked the box to activate the second monitor with the "Virtual resolution" adjusted. It told me to log out then log back in.
I accordingly logged out but then couldn't log back in. It had evidently changed the resolution not only on the 2nd monitor but also on the laptop monitor. A box was visible on screen but completely illegible/unclear since the laptop monitor couldn't display that resolution.
After a few restarts and button pushes it is now restarting at a terminal (I enter my username/password at a command prompt on an otherwise blank screen rather than the graphical interface loading up).
Question: are there any commands that could change the resolution back to its original settings then restart the Ubuntu graphic interface? Some thing similar to the "load with last known good configuration settings" option in Windows maybe.

My ubuntu isn't starting up today. I can't remember anything unusual happening last night, not even a standard system update.
It presents me with the Grub loader, screen goes blank, and that's as much as I get. I have gone into a recovery mode through the grub loader, and that gives me a bit more info, but I don't know what to do with the information it is giving me.
It says: Gave up waiting for root device. common problems (etc) ALERT! /dev/disk/by-uuid/<long name> does not exist. Dropping to a shell.
It is right - the /dev/disk/.... does not exist. A different file with an equally long filename does exist

Last week I very eagerly downloaded Ubuntu 10.04 and burnt it to a CD. I just want to try out the new version using the Live-CD. I tried it on both my home desktop and my work notebook. I was able to get the initial screen where I can select the language and keyboard, etc.. But when I tried to start the program I ended up with a blank screen one both computers.
So I just thought, I will wait until they get these problems fixed then I will download and burn a new cd. Question, have their been fixes to the ISO file since it first was released that would fix these kind of problem? How does one know if the ISO file has been upgraded; is there something after the 10.04.01 or something like that?

So finally decided to upgrade the desktop (dual-booting with Windows 7 for games) from 9.10 (fresh install awhile ago, never did anything with it) to 10.04 - upgrade went fine, reboot, watch grub go by, and voila. Blank screen.
Things I tried in grub:
add 'xforcevesa'
add 'xforcevesa' & remove 'quiet splash'
add 'nomodeset' & remove 'quiet splash'
add 'nomodeset xforcevesa' & remove 'quiet splash'
[Code]...
I was hoping to test out Windows 7 in a VM, see how far I could get for GPU acceleration there - I'd much rather not run Windows on the bare iron for that machine, but if I can't get this fixed I have no option :-/
