Software :: Text Is Colored Pixels During Boot?

Sep 11, 2010

I recently upgraded to Ubuntu 10.4 and, although that installation seemed to work OK for awhile, I have recently encountered a strange problem. I have a dual-boot system with Win XP and two releases of Ubuntu, 10.4 and 9.10. I installed the latter recently only to be able to run some legacy software. I believe the problem occurred sometime around or after the installation of the 9.10 package. Note that the 10.4 install was a clean install on a newly formatted HD, and not a normal upgrade from 9.10, which I installed later separately. The Ubuntu installations are on their own HD. Win XP is installed on its own separate HD.

Here's the problem. I can boot OK up to and including the appearance of the Grub 2 menu, which displays fine. From the menu I can chose Ubuntu 9.10, Win XP or several kernels of 10.4. The 9.10 Ubuntu boots completely normally, as does Win XP--no problems or irregularities with either of those. When I select one of the 10.4 Ubuntu kernels, the strangeness begins, as follows:

1.) The menu disappears, there is a brief period of blank screen, and then a bizarre screen appears. It has a violet/magenta background. The word "Ubuntu" appears in large type, with a couple of lines of text below it. However, all of the type is unreadable. Instead of being normal characters, all the text characters are displayed as blocks of seemingly random multi-colored pixels! I can recognize that it is supposed to be text, but the letters are just a bunch of colored pixels. I can recognize the large Ubuntu word because of its shape. Also, the whole text display occurs twice on the screen, one on the left and one on the right. Both are displayed as colored pixels.

2.) The screen stays there, as if frozen, and does not continue with installation of the kernel. After some experimenting, I discovered that if I press Ctrl-Alt-Del (!), the installation continues as one would expect: I soon get the normal login screen, am able to login OK, and my desktop soon appears as usual.

3.) However, once in the desktop, if I try to invoke a console window by pressing Ctrl-Alt-F1-6, the console window appears, but the text on the screen is again rendered as little bunches of colored pixels, completely unreadable. I can, in fact, login at these screens, but the text remains colored pixels. I can escape back to a normal desktop by then pressing Ctrl-Alt-F7, and the desktop comes back completely normal. Interestingly, if I invoke a terminal from the main Applications/Accessories/Terminal menu, I get a normal terminal in a desktop window that is perfectly usable.

4.) If, from the boot menu, I choose the Ubuntu 9.10 choice, everything works fine and as expected, including the Ctrl-Alt-F1-6 console windows. This problem only occurs with the Ubuntu 10.4 menu options.

Since this problem only occurs with the Ubuntu 10.4 menu choices, my guess is that there is something askew in the display configuration of those specific choices. But, I've not discovered what to check for that configuration or how to correct it. I've checked out the /boot/grub/grub.cfg file, the /etc/grub.d number files, and /etc/default/grub, but can't find anything that seems to be the cause or the remedy.

Ubuntu :: Multi User Logout Freezes With Black Screen

Aug 26, 2010

I have Lucid setup for multi user. Whenever 2 users are logged in and one logs off, it freezes on a black screen. It looks like it logs off OK and is on its way to the main login screen but never gets there. I found some older posts describing this problem but no solution. I tried to post to that thread but got a message saying I was not permitted. I am new to Linux and am struggling to figure out how to problem solve issues in Ubuntu.

Then darkness without There is one way to start up and getting screen (which I'm using now).

Fedora Installation :: F15 Upgrade Black Screen

Jun 25, 2011

I upgraded my machine to F15. I was asked to reboot. From that point on, the system will not boot. I get to the blue screen with the 'egg', about 1/3 of the 'egg' turns white, then the screen goes black. No cursor, nothing.

I hit shift to get the Grub menu, tried booting my old kernel. Same result.

I tried burning a F15 live cd and booting that, but I get a desktop background with no mouse, no docks. It doesn't seem to respond to anything I do. I can boot it in the "basic graphics" mode, or whatever you call it, but I would rather not overwrite my entire hard drive with a fresh install.

I have seen references to some kind of recovery mode provided on the live cd that might repair my install without wiping my data, but I can't find it anywhere.

My hardware:
Dual core Atom D525
Intel NM10 chipset

Ubuntu Installation :: Stuck With Black Screen On Booting After 10.04 Upgrade / Fix It?

Apr 30, 2010

Yesterday I upgraded from 9.10 to 10.04 via Update Manager. But when the upgrade procedure was finished and I made a reboot, I only come to the Ubuntu logo appears for a second, then the screen turns completely black and nothing happens. I then have to reboot via the power button.

But I can get it working with so far no problem, by booting to the third option in the boot options list. In the list there are several options, something like this code...

Now the question is; what does this mean when there are several alternatives with the same name? What is the difference between alternative 1 and 3, other than 3 is working and 1 is not? Is there any problem running alternative 3 instead of 1, and if so how do I get it to boot from alternative 3 as standard?

If this is not the right way to do it, how can I figure out what the error is on alternative 1?

Ubuntu Installation :: Black Screen After Upgrade 10.10 To 11.04 Acer EMachines?

Apr 30, 2011

Got a black screen after upgrade from 10.10 to 11.04. My Computer is an Acer eMachines E527 [URL]

I) Just started Computer normally, using new Kernel and 11.04 then the screen became black as before. Waited until Harddisk (Light) wouldn't work too much and boot seemed to be over.

II) IN BLIND FLIGHT (without seeing anything, since screen is black):

1) opened the Terminal using Ctrl+Alt+F2
2) typed my "Username" (enter)
3) typed my "Password" (enter)
4) typed "sudo setpci -s 00:02.0 F4.B=30" (enter)
5) typed my "Password" (enter)

III) Now it is not really satisfactory to do this over and over again each time restarting my computer. Is there any way to use a batch or use the grub to setpci ? I'd like to install 11.04 with an USB Stick on a similar computer - how do I setpci there?

Ubuntu Installation :: Upgrade From A Live Disk - After Grub The Screen Is All Black

Oct 21, 2010

My ubuntu desktop died yesterday. I rebooted my computer in like 1 month and after grub, the screen is all black and it stays there... forever. So I decided to see if the problem persists or not when I completely upgrade my ubuntu to the latest version. So I downloaded the latest ubuntu iso from the site, burned it, and booted from CD and I see several selections to choose from the menu list. The second one was "Install Ubuntu". What I'm worried about is I don't know whether selecting 'Install Ubuntu' will erase all my previous data, or there will be an option to upgrade Ubuntu without erasing all the data. Is it safe to install from the live disk? Will my data be safe? Is there any way to upgrade my Ubuntu on the HD to the latest Ubuntu from a live disk?

Ubuntu Installation :: 9.1 - Can't Get To Boot - White Pixels At The Top Most Row Of The Screen

Feb 23, 2010

I recently downloaded Ubuntu 9.1 and burned it to a CD. However, I can't seem to get it to boot. I got to the main menu and selected to run it directly from CD, and the Ubuntu symbol showed up saying it was loading things, but then the screen went black and nothing happened even if I waited over 15 minutes. During this time the HDD light was flashing every second or two, and I could see about three white pixels at the top most row of the screen.

Ubuntu Installation :: Screen Chantges To Massive Amount Of Colored Static

May 15, 2010

ive been trying to install 10.4 as a fresh install from a LiveCD. I downloaded the 64 bit ISO (I use Win7x64 normally, my processer is a core2 duo 2.2ghz or something along those lines), booted it up, and it starts loading. after a while, the screen chantges to a massive amount of coloured static. I tried reburning the disc, but it made no difference. Im now redownloading the file and the 32bit version too. Is this a problem anyone else has had, and if it is, is there any way to solve it? I would really like to use the 64 bit version.

Fedora Installation :: 10 - Graphic Drivers - Screen Showed Only A Bunch Of Colored Vertical Lines

Feb 10, 2009

I recently downloaded and installed Fedora 11 Alpha. I then installed the Nvidia drivers for my Graphics card (GeForce 7800 GTX). I discovered that Fedora 11 is using a Beta version of Xorg and an incompatible ABI. So, my drivers would not work with Fedora 11 without me dowgrading the Xorg server. I decided to reinstall Fedora 10 instead.

I started the install, and when the installation loaded the generic video drivers, my screen showed only a bunch of colored vertical lines. Fedora 10 doesn't allow me to install in text mode.

Ubuntu :: Upgrade 10.10 Fail - Black Screen Gnome

Nov 2, 2010

Yesterday I attempt to use update-manager to do a distribution update. all was going good. i went to the kitchen to get a coffee and returned to a black screen with no cursor. the install couldnot have finished as it was still downloading updates i believe.

on reboot gnome did not respond so my last resort was to use kde for the time being. by running update-manager through kde I successfully updated to ubuntu 10.10. After completion of the update i restarted and gnome still had a non respinsive black screen on login.

Kde is still working fine.

Or at least how can I completely reinstall gnome.

Ubuntu :: 9.10 - Colored Screen With Strange Symbols

Feb 13, 2010

I'm using Kubuntu 9.10 and I have a problem with my screen. I use the nvidia driver downloaded from the website, installed manually as I always do. I wanted to update it, but when I press ctr-alt-F1 to go to the console to stop kdm, I cannot see the usual black screen, but only a very strange blinking screen with lines and colours, strange symbols like $ & %. This happens for every F1 until F6, then F7 luckily brings me again on the graphical desktop.

I tried to install the drivers from the "Hardware drivers" manager in Kubuntu, but nothing changed. I don't know if it's an issue related to the kernel or to the driver. But I don't know how to update it without F1 console, and however it's a serious issue because I cannot do anything in case of desktop failure. The kernel is the last officially released (I don't use the proposed repos), that is 2.6.31-19.

Ubuntu :: Screen Position A Few Pixels Off?

Oct 24, 2010

In 10.04 on a Shuttle the screen position is a few pixels off. I fix this with xvidtune for the session. I also get a new modeline. I build a new xorg.conf file (go virtual terminal, stop gdm, Xorg -configure, etc) and move it to /etc/X11. I introduce the modeline in the monitor section and reboot (I could do a service gdm stop...). Guess what, my screen is still a few pixels off. The documentation clearly states that if there is an Xorg.conf, it will be used. So what gives?

This problem has existed since the xorg.conf file was dropped. It is just plain silly that one has to engage in a geeky treasure hunt to correct a few pixels. This adjustment should be present in the System/Preferences/Montors. This is why Linux does not make it with ordinary users, making (superficially) simple things difficult.

Ubuntu :: 10.10: Menu Pixels Freeze On Screen?

Dec 7, 2010

Eee PC 1005HA : Ubuntu 10.10 Netbook Remix, using Desktop Edition at login screen, using Awn in place of Unity: No clue what's causing this. Menu pixels freeze, remain on top of windows. Cursor floats over, but interacts with the actual active window. Can't move it. This has happened several times now, but usually only lasts a few minutes. At the time of this post, these pixels have been frozen for at least 20 minutes. Relogging fixes the problem, but logging out and in again every time this happens isn't really an option.
