Ubuntu :: System Freezes With Black Screen And Message
Sep 10, 2010
I'm using ubuntu 10.04 and it worked fine but recently I'm getting the following message -
(process:343) GLib_Warning** : getpwuid_r(): failed due to unknown user id(0).
This message comes with a black screen and then no key stroke works and everything totally freezes. then I've to force restart using power switch. This message appears when I'm using internet. I'm using pppoe broadband connection. Without internet it works fine. I'm getting the same prob in Linux Mint 9. I've googled for this problem and almost everywhere it is said that this message appears in booting time and after a few moments everything becomes quite ok but my problem doesn't match with them. I don't get this message in booting time. I get this message when I'm on internet.

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.

I have used Universal USB Installer to extract the xubuntu 10.10 iso and install onto a flash drive. I would like to try a live version of xubuntu that boots from a flash drive. When attempting to boot from the flash drive, the screen effectively freezes after displaying the syslinux / ebios copyright message, with a flashing cursor.
Does anyone know a possible cause or solution? Information that may be useful: I am using a 4GB flash drive, formatted as FAT32. I formatted once using the Universal USB Installer, but some files were left on the drive, so I have reformatted it using the option provided by the Windows interface, (and reinstalled xubuntu.)
When I opt to install onto USB with a 2GB persistence file using Universal USB Installer, the installation processes hangs with a dialogue saying there are 0 seconds left to copy, until the dialogue is forcefully shut (and installation appears to be successful). When I select no persistence file, the process does not hang. (I am faced with the same aforementioned problem at boot time, regardless.)
I have not checked the md5sum (though I have no reason to suspect it will fail.) I have downloaded a simple programme which checks a single md5sum against a single file, although I am unsure which file I should check against in the case of xubuntu, and if the md5sum.txt file represents a single md5sum.
I am using Windows Vista on an old Toshiba Satellite. I am new to using linux, and am very unfamiliar with the the setup and installation procedure.

I decided I wanted to give ubuntu a go by installing it on a 4GB USB drive.
I installed it using this guide url.
I booted up and it hung on the 'mounting file system', I left it for ages and eventually it goes to a black screen and prints out an error message, I can't type anything on my keyboard.

I installed Slackware 13.1 a little bit ago, played around with it, performed an upgrade with Slackpkg, messed around with some settings, and chose a new theme. I had set the runlevel to 4 and when I rebooted after choosing a new login theme the screen just went black at the point where the login prompt should have appeared. I couldn't even get into the CLI. Using a LiveCD, I set the run level to 3 again and was able to log in, but when I try to start X the screen goes black and freezes again, so I believe my new login theme is the culprit. Is there a way to change to the default login theme from the CLI?

Was running Server 8.04 with graphical desktop - no problems. Wanted to upgrade to 10.04, so ran sudo do-release-upgrade --proposed
Upgrade was successful (although so much stuff scrolled by, it's hard to tell if something errored along the way).
Server rebooted and a dark maroon screen said 10.4 is booting, ntp service started etc. and a scrolling series of dots.
Then got a sky blue patterned login screen, so I logged in. Screen then went black, with a movable mouse pointer.
If I do Alt-Tab a panel pops up saying ** NO WINDOWS **
Using Ctrl-Alt-F1 (iirc) got me a command prompt, so I logged in there and ran: startx
This gives me the message:
Fatal server error: Server is already active for display 0 If this server is no longer running, remove /tmp/.X0-lock and start again
So checked runlevel (who -r) and that was set to 2. Changed /etc/init/rc-sysinit.conf so RUNLEVEL=5
Rebooted, logged in again, still got black screen + mouse, and **NO WINDOWS**. Logged into terminal and runlevel=5.
Also tried running dpkg-reconfigure xserver-xorg but that returns immediately without anything apparently happening(?).
how I can get my KDE graphical environment back up ?

I have the normal OS choices menu (Windows XP or Unbuntu) but when I choose ubuntu I get an instant flash of an error message on a black screen so quick I cannot read the whole thing but I caught "error" and "format" and then the computer reboots. I have no problem getting into Windows.

Tried the DVD install for 10. Install went fine other than it take for freakin ever, but after an 1 hour install, the update wanted to install 1675 or so updates. I let those updates install. 5 hours later the updates were done. Rebooted and now it freezes at a blank screen right after the 3 scrolling bars. System is older AMD 3000+, 1 GIG RAM with NVidia 5700 video card.
I did try and search some. But the only thing I could find was something about editing my grub file for a scan=sync setting (the information was basically gibberish to me. No clue what it was talking about or how I would edit a file on a system that won't boot). I tried to recover mode off the live CD. It had some options that said you could type Linux command line arguments, but whenever it got to the sysimage it says Linux isn't a command.

The screen of my years-old HP laptop (running Natty) freezes and eventually turns black. Ctrl-Alt-F# works to switch to the terminals. My fan is even louder than usual. I spend some time fooling around with ps and kill and shut down some of the most resource-consuming processes, which quiets the fan a bit, but tty7 still shows a black screen except for my mouse pointer.
I finally decide to shut it down altogether, but then I think to myself, "Self, you've used the power switch to shut down before in this situation, but shouldn't there be a more proper way to do it in the terminal?" So I try shutdown, I have trouble with it, it proceeds to get hopelessly tangled up, and it looks like it's frozen up in mid-restart when I throw up my hands and decide to go for the old power-switch-for-five-seconds method after all. Now when I start the computer and select Ubuntu from GRUB, I get this:

F9 has been running great since it came out. I read that one should install F10 before F11 so I did install F10! Everything went great.
(1) Then I tried to install the F11 iso dvd. After the "anaconda started" message at the bottom of a blue screen, the screen went blank and occasionally the message would appear: "cannot display this mode 2:dvi-d". Thinking the monitor had gone into power save, I hit many keys and moved the mouse to no avail.
I gave up! BTW I had checked all media CDs for errors.
(2) then working under F10, a little message appeared from the lower right of the screen asking if I wanted to upgrade to F11.
I accepted and again "cannot display this mode 2:dvi-d" on a black screen after anaconda started on a blue screen. This time no ISO DVD F11. I've never seen such an error message in 11 years (off and on) of using Linux. HD Disk activity was showing on the disk activity light so I let it run all night and part of today. I hit a bunch of keys and moved the mouse and the blue screen returned saying all was done and restarting.
After restart, I seem to have F11 installed. I did a yum update and got some more F11 updates. On the grub screen, the only F11 kernel was the PAE kernel which I selected
and got:
Does F11 have any F11 kernels? BTW running >setup (hd0,0) under F10 grub ruined my XP prof OS on scsi 0 so I reloaded XP Prof from scratch.
Questions:
(1) what is this "cannot display this mode 2:dvi-d"?
(2) Now I cannot boot to Fedora 11 and all the advice on how to reinstall grub has failed failed. Did a rescue and chroot /mnt/sysimage and the fdisk -l
Now XP Prof seems to be on /dev/sdc and Fedora on /dev/sdd. What do I do? In the meantime I have retreated to Fedora 10.

if I reboot the computer, I get the grub menu and am able to choose between Win7 and Fc15. A couple of times during installation the screen flashed black and diplayed a message for a brief second. I can't read that fast but it says something like "DRM nouveau- unknown or unsupported chipset" and one more line that I can't catch. When this happens, I see the pre-login loading screen, the one that shows an icon of a hard drive, network, and so on as each resource is secured. I can log back in, but this starts a new session- it doesn't remember what I was doing. I had to redo the install and setup several times because of this.
I can log in and so on normally, but the black screen and message will appear at random, forcing me to start all over, which is really frustrating. what's going on? Is it the video card? How do I install a driver for it? Also, the hard drive in question has been through a lot. could it have a bad sector or something? Windows didn't even want to "see" it, that's why Fedora is installed on there.

I burnt the Ubuntu 9.10 ISO to CD and installed on a freshly nuked Dell 2350. It is pentium 4 at 1.8 MHZ with 512 RAM. Just a spare machine I have sitting there. Install went fine, restarted box, boot from hard drive. I get the little white Ubuntu symbol on a black screen and then a black screen with un-occupied white tool bars at top and bottom of screen and a functional mouse pointer, then nothing. It freezes there.
If I restart by holding the power switch in it occasionally shows multiple CPU overtemp messages and freezes with totally black screen. I can run the CD live and everything works like a champ. I'm going to like Ubuntu once I have this sorted out. If I boot from CD and choose the run from first hard drive option, everything loads and works fine. I was able to remove CD, update and save preferences, etc..
On one occasion, I was able to restart and boot from hard drive and it worked fine but usually it freezes at previously mentioned black screen with white bars top and bottom with mouse pointer. Please excuse my ignorance as I have very little knowledge of the inside workings of computers. I didn't even know about burning ISO's or changing boot orders until reading online. For what it's worth, the computer worked fine with no known hardware problems when it was running XP. It also is completely stock with no mods or added/replaced hardware.

I keep starting up the computer and I'm not able to get far (although it's not always at the same time) before my screen will go black, except it shows the mouse/cursor - but it's frozen, and then the caps-lock light starts blinking and I can't do anything or get it to recover. It ONLY occurs after I log in to wireless network. Using a wired connection, this problem never occurs.How do I stop this and diagnose this?I've tried, in the boot-startup to choose an older kernel version, but the same thing occurs! And this was working for months and now is not.

Don't know if this is a coincidence, but the other day we had a power cut and my laptop went off. When I tried to reboot it got to the ubuntu start up screen, but when it tries to get to the "desk top" screen it all goes blue and black flashes. I have XP and Vista on the same machine and these both start up ok

Every once in a while when I turn on my computer it freezes on the purple screen after the screen where you choose the operating system. When this happens the keyboard doesn't work and I have to hold the power button. Also I think this might be connected to the problem I had when I was running ubuntu from the live cd, which was freezing after choosing the option of "trying" the OS before installing. I'm using an HP Dv7-3112sa and am running the default 64bit ubuntu from the website.

I just got an update notice two hours ago and after updating I rebooted my machine to find that it no longer boots. The update was for 23 bug fixes for Nvidia drivers and Nvidia support software. I get a black screen with the message "serial8250: too much work for irq17" and a blinking cursor. How do I recover from this?

The system freezes after the screen saver. 'Blank screen' is used. I can't do anything, so I reboots the machine from another terminal. I am using CentOS 5.4 x86_64.

The system frequently freezes the screen. The mouse is still moveable but there is no reaction on any click. Keyboard does not work either (pushing Num-Lock does not toggle the Num-Lock light on the keyboard). However, Alt-Print-b works for a reboot. The only other way out is to turn of the computer.I had this effect some time ago where I thought it was a problem due to the NVIDIA graphics driver. Since then, I changed back to the standard VESA driver and thought the problem would be gone. Just a thought
I toggled through the log files in /var/log which had the file date/time of the crash but I could not find any hint.Which log files could I look as well to dig for the problem? Or any idea for such an effect?

I recently upgraded from Hardy to 9.10 Kubuntu. The install went smoothly, and when I boot up, the loading screen (the one with the progress bar) does its thing. Then I see the 'waiting' cursor (in Kubuntu, the two dots chasing each other around in a circle). I see this for about two to three seconds, then the entire thing freezes up and I can't do anything, including switching to a virtual console. How do I figure out my system's dying words so I can figure out what's going wrong? As a (sort of) aside, when I open files in /var/log for reading with cat <file> | less, I have to Page-Down a whole bunch to get to the most recent stuff. Is there a way to jump to the bottom, or read with something other than what I have been using?

I upgraded from 10.10 to 11.04 and after the upgrade
- the system boots,
- the grub menu appears,
- the splash screen comes up and then
- I have a black screen and that's it!
I saw, at the end of the installation process, that the driver for the nVidia video card was removed.

I was messing around with the screen orientation and thought it would be funny to orient it sideways. Big mistake The screen went black.I can force a shutdown, login and I get the same black screen. I tried hooking up an external monitor and the monitor showed no input so I'm guessing my laptop doesn't have that capability with Fedora.This is my main computer.

I love it but I have a problem that someone can hopefully help me troubleshoot. The system intermittently crashes, the screen freezes and nothing works except the mouse pointer which can be moved but not used. Is there a way for me to diagnose this

I did a system update earlier in the day, but I have a hard time thinking this is connected to it:
I shut down my computer and when I went to start it up, I got a black screen and a bunch of letters and numbers followed by:
Is there something I can do to get back to my desktop? Is there a way I can access my documents, at least?

I am running ubuntu 10.4, windows 7, and I had ubuntu 10.10 on a single hard drive. I upgrade the 10.10 system to 11.4 and now my grub menu which is on the 10.4 system shows two windows and two 11.4 installations.
How can I clean this up? Also I have tried to start with the grub 1.99 on the 11.4 system and all I get is a black screen at startup. I am happy with grub on 10.4 except for the extra lines.
