Ubuntu Installation :: Flashing Screen On 11.04?
Apr 28, 2011
I've just downloaded and installed Ubuntu 11.04 (amd64) and every time I boot i get a flashing screen. I didn't have any problems at all with the LiveCD. The graphics card and my wireless adapter worked out of the box. But after the install it won't work. I can choose the OS in GRUB and then there's a purple screen. After that the screen starts flashing and I can hear the login sound.
I have tried using "nomodeset" but that didn't work either. There is no flashing, just a purple screen all the time. But it was possible to enter tty. I also tried booting the Recovery Mode but it just loads and then a pink flashing screen appears.
The graphics card is a XFX Radeon HD6870 1GB.

I just recently installed Ubuntu 10.04. Every time I boot it up the screen flashes, like going off, then on again. It won't stop doing that. I can see the screen for 1 sec then it goes black, and keeps repeating this.

Just installed Ubuntu 9.10 side by side with XP. When trying to run ubuntu from Grub the terminal screen opens but then starts to flash. This makes it difficult to type and login. When I do eventually login it just goes no further than a terminal prompt.If I use recovery mode the screen does not flash but still cannot get to the desktop

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 having this problem with Ubuntu 9.10, it has happened the three times I have tried to install it.
I have made a video showing the problem: [url]
After upgrading and rebooting, the flashing login screen appears and it is not possible to use the GDM.
I have tried to install KDM and it works, but when trying to load gnome I get the blinking bars again.
I have also tried this (and got the same problem); installing the Nvidia driver (manufacturer), installing the Nvidia driver (repositories) and installing no screen driver.
I think the problem is with GNOME, and not with the graphics card.
Now I have installed windows xp :-/, for the first time in a whole year, cause it is not possible for me to use Ubuntu 9.10 at all.

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
CPU

i am trying to instal kubuntu 9.10 on my desktop. i have an ati radeon hd 4600 with a hdmi cable going into the 22" lcd. The problem is i cant view the whole desktop, like i can only see a part of the corner, and all of the icons are massize. The search bar at the bottom comes to half my screen size, making installation impossible to see. Plus i can only use live cd mode using safe graphics mode. i am new to linux finding this quite confusing.

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.

became immediate to me is that the docks on the top and left sides of the screen lack icons.On top of that, when you hover over where I suppose icons should be, the black tooltip that comes up is labeled with a white rectangular block instead of telling me what the icon represents. It looks as if the applications function fine regardless of this phenomena; I can click on different parts on the dock and the icons' links still pull up the program with no issue.
Opening up Firefox, however, led to the screen flashing a colorful pixelated pattern that looks like what happens to an image when you take it into Photoshop and run it through a coarse mezzotint filter. It flashes occasionally while using Firefox, both around the window, on top of the window, and on the entire screen. I've also found that I can't run Firefox for more than five-ten minutes without the system freezing on me (mouse won't move, screen doesn't change).

After installing Ubuntu Server 10.04 LTS, I restarted my machine. I removed the disk, but now when it starts, it never gets to GRUB. Instead, it just takes me to a black screen with a blinking cursor. I can't type in anything and holding shift doesn't take me to GRUB.

Despite being warned from a friend of mine who works for Intel that the new version of Ubuntu 11.04 sucked? I upgraded from 10.10 which worked perfectly fine and did everything that I wanted it to except work with my COBY MP3 player which is what I hoped 11.04 would do. It all worked great until I rebooted. I previously had the main screen on the left where all of the menus are and the right screen was the 2nd monitor.
Once it rebooted it let me login and loaded the desktop but the main screen is now on the right with that stupid application bar going up the side, all of my folders, etc. are all there but NOTHING is clickable, even the icons up in the right corner where you logout, etc. will not do anything other than highlight that you have clicked on them, the hard drive light flickers for a few moments then nothing.
Also the left hand screen is completely blank unless I move the mouse cursor through it. If I just leave the computer sitting there eventually the screens go dark and the monitor lights start flashing like it is supposed to but if I wiggle the mouse the screens come back on and the mouse is there but there is no login prompt to let me log back in. Pardon my French but this OS is a piece of <bleep> and sucks just like I was told.

After an aptitude safe-update my laptop doesn't boot any more.
I recorded the following video of the boot process: [URL] ....
The disk is fine (I ran fsck), GRUB in OK. Could it be X?
I can boot in safe-mode and also have internet connection, so not everything is lost ...

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 cannot install Ubuntu 10.04, or even boot into the live CD. I'm not an expert, but I've used Ubuntu for several years, and I'm pretty sure I'm not doing anything stupid... Here's what happens when I boot with the Ubuntu 10.04 live CD: I get a purple screen with just an accessibility(?) symbol at the bottom (this lasts 15 seconds). The screen goes black, with a flashing cursor, then changes back to purple, this time with an Ubuntu logo, with 5 dots acting as a progress indicator (this lasts about 1 minute). The screen switches to standby. The CD drive continues to make noises for another minute or so, then stops.
I physically removed my graphics card (ATI Radeon HD 5770), and plugged the monitor straight into the VGA port on the motherboard. Now the CD boots up fine. I could try installing Ubuntu at this point, while my graphics card is unplugged, and then plug my graphics card back in, and see if it starts working then.

was trying to get rid of the ubuntu menu and try to change how the desktop looks. It's hard to explain but it was first the desktop you get when you first start up ubuntu on NetbookThen I somehow turned in into a desktop esque menu. With all the icons and stuff. Today my battery accidentally fell out as I moved it around and when I restarted my computer all went fine until the screen started flashing. On the upper right hand corner, was a transparent square with 2 arrows when it flashes. It still showed that I connected to my wireless and etc.

I tried to enable Compiz on my netbook, so I installed ccsm. Then when I enabled visual effects and restarted, my netbooks monitor starts flashing when I boot up. So I restarted in low graphics mode, uninstalled ccsm, and it's still flashing. Is there anything else I need to remove to get my netbooks monitor back to normal?b

Recently, whenever I restart my computer, I am automatically logged in and a rapid sequence of flashes repeats itself over and over. First a white screeen appears. Then my desktop background appears, dimmed and overlaid with the netbook-launcher's up and down arrows in the upper lefthand corner. Then my desktop background appears in full color, with my panel above it but no launcher. Rinse wash repeat. I assume it has something to do with Compiz. When escape to a tty and type "compiz --display :0--replace &" the loop ends and everything works. Any ideas how to avoid having to do this every time I restart

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.

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)

when I install them all goes well but when I get into the GUIs I can hardly press anything - major bug with mouse and it is really annoying. Secondly there is a big gap between the GUI and my screen's edge. Hmm, I think - it must be a problem with the GPU driver and that might be the thing also messing with the mouse clicks. I download the drivers provided by the Ubuntu community - all goes well and I restart - stuck at purple screen after the "moving dots" on boot. So I reinstall the whole OS and try with the drivers provided by NVIDIA - same thing. I try the same procedure with Kubuntu and no progress.

I've installed Ubuntu 10.10 Netbook to my sisters laptop (Dell Latitude C640) but there appears to be a problem with the screen going black then opening the primary window, then loading the sidebar and then going black again.
For example, I'll hover over the new bar on the left and it'll just disappear, the screen will go black then will suddenly come to life again and then disappear, go black and so on. It just cycles through that.

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
