Ubuntu :: PC Freezes Up / Screen Greys Out
Sep 5, 2010
My Specs:
!0.04 Lucid running on:
Compaq Presario M2000 Notebook
Processor: AMD Turion 64
Graphics: ATI Radeon Xpress 200M
1GB Ram
I have had this happen only while using Firefox 3.6.8. This never happened with previous releases but they were using older versions of Firefox. That said I can't be 100% sure it's a FF issue but I think it is. I'll be online and suddenly the display will grey out, the CPU and will ramp up and I will loose control of the PC. Often it will return after a few seconds but not always. If control doesn't return I am usually screwed and can't even shut the system down. Initially I was thinking it was a Flash problem and both FF plugin Container and FF bin would be consuming vast ammounts of the CPU.
Now though I'm not so sure. I've tried deleting the FF profiles and starting again but this doesn't help either. A week ago I took the radical approach and completely deleted the partition and reinstalled a new version of 10.04.1 All was fine until a couple of days ago. But it started again. The screen greys out, everything freezes and I have no mouse/keyboard control. I tried to open terminal and no response. I try to shut down and my desktop icons dissapear, then the top/lower pane and I'm left with just the background and the cpu fan running full blast.
This last time I had terminal open with top running just in case. Problem stars again, greys out/freezes up etc and what I notice is Nautilus is using 99+% of the CPU. At the same time I loose my icons, panel toolbars etc. Now this is a fresh installation so what on earth's going on? It's happening on only one of my PC's The only other thing thats popped up is I've got an error message of "input/output error" a few times both in the Shell or again today struggling to get Terminal open or the pull down menu to restart the system. Hardware issue?

Sometimes after I enter my password after the screensaver has locked the screen, it will not take my password (even though entered correctly). It seems to lock up. After about 2 mins it says something about a time-out (wish I could do screencaps). Then it will reset and have a gray window the same size as the password input window but on the upper portion of the screen, and a password entry window as normal, but in the lower part of the screen. This time, it accepts the password and logs me in.This is a 2-part post.First, how to bypass having to wait for the timeout (for whatever is timing out).The second is to see if anyone knows an answer to the problem and a fix.After it freezes, hold CTRL-ALT and tap F1.This will taking you to a virtual terminal. Log in with your username and password. Then type:
Code:
$ pkill screensa
This will match gnome-screensaver and kill the program that is frozen. You then need to type
[code]....

I got a problem with ubuntu and it is when I try to play games everything works alright but suddenly I get a random freeze, my entire screen freezes and I have to reboot in most cases, sometimes it turns to normal after a while. I had this problem in 9.10 and I got nvidia GTX 275. I dualboot with windows.
It could be my fans that are not working as the computer temperature gets up to 43 C or something when I game, however I've not seen how hot it is when it freezes.
Oh and I use 10.04, had the same bug in 9.10

I've been using 10.04 for a while now with no problems but for some reason it started freezing on the splash screen, 2 of my keyboards lights start blinking and thats it, I've tried with recovery mode and no luck either. The thing is I don't remember doing anything wrong.

I've had Ubuntu for months but now it freezes at the login screen. I've written what I did when I last used Ubuntu in a post below. (like undo the xorg upgrades?)

When ever I choose suspend to shutdown the hard drive slows and the picture on the screen freezes. The mouse and kb are disabled and the cpu fan keeps running. My hardware in in my sig below I have turned off automaitic updates straight after installing from disc as the last time I had it switched on after a few updates I got repeated ata drive read errors and the pc would freeze for a while being unable to read from the hdd. I have run wd diagnostics on the drive and it works fine. To fix this problem I did a clean install after messing round for 3 days and achieving nothing. I have an arch partition that works fine as well although I have not attempted to get suspend working with it. ( hal error) I have read a few thread on the net and tried entering the swap disks uuid into grub.

I tried to install ubuntu 9.10 with the live cd, but my computer freezes on the welcome screen, where you select the language (for the second time).After that the ubuntu logo starts pulsing and after a while the welcome screen appears. At this point, my mouse and keyboard are frozen (though the laser is still working) and the only way is to turn my computer off. I can't even eject the cd rom.

I recently upgraded to the 9.10 version of Ubuntu. Now my screen freezes from time to time and I cannot click on anything. I must do a hard reboot by holding the power button of the PC. Is there a fix for this? Is there a way for me to go back to 9.4?

I am running Ubuntu karmic with Gnome desktop
I rebooted it as a package (GRASS GIS) wouldn't open properly, the splash screeen appeared but it appears to freeze and does not get to the login screen. I have tried to boot in safe mode but pressing ESC at grub doesn't work and Ctrl+Alt+F1 also fails to invoke anything. I can connect remotely via ssh. I have tried to remove Gnome desktop so I can just go straight to commandline but it still brings up the splash screen, I removed desktop using sudo apt-get remove gnome-desktop it said it did.
So why did this happen, last night I logged in via ssh and x-win server started a screen and did some work, the x-win server I lost my internet connection so putty aborted, this morning I couldn't connect to the screen so I did screen -wipe then rebooted as another package kept exiting.
any help much appreciated, this has happened at a vital time during my PhD and I need ubuntu back asap! In the meanwhile I am working via ssh with a slow Internet connection so not ideal!

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

I have finally successfully triple-booted Snow Leopard, Windows XP, and Ubuntu 10 on an iMac but I have 1 problem: Whenever I am in Ubuntu and select "Restart," it goes to the splash screen and loads 2 of the dots and then freezes and hangs there forever. If I do "Shutdown," it works properly. Note: I am using rEFIt as the triple boot loader. GRUB installed on sda3 with Ubuntu.

Today I upgrade my Ubuntu 9.10 pc to the latest Ubuntu 10.04 LTS. The upgrade went perfectly with no errors. But when I login to my account Ubuntu loads but then the screen freezes and nohing happens. Then I am just left with a blank desktop with only the Ubuntu 10.04 background and no panels.

I upgraded a week or so ago to 10.04, and everything was working fine. Then suddenly a few days ago the computer froze at the splash screen on startup. Thinking it was just some sort of neurotic, temporary issue, I restart again, but no luck -- same problem.
In terms of what I changed before the problem happened, I don't recall changing any system settings. On possibility is my changing things to skip the login screen and go strait to my account, but I believe I had done that a few shutdown/restarts before.

I just updated my netbook remix 9.10 to 10.04 and every time I boot up it freezes as soon as the login screen pops up. Before this said screen pops up I have the ability to move the cursor around freely, and if I mash the life out of enter I can get it to select my username, but freezes before the password entry bar has the chance to come up under it.

Yesterday I upgraded from 9.10 to 10.04 (32 bit). Everything seemed to go well with no errors until the point where the system needed to restart at the end. After it restarted (and every power cycle since), it gets to the "ubuntu" screen with the moving cycle of square dots underneath, and stays there for ever. The screen resolution is absolutely goofed up, the word Ubuntu cannot be clearly read (looks like it is way overdriving the monitor). All letters seem to have like vertical bars on either side.
Below the Ubuntu and the dots, there appears to be two lines of completely illegible text (they just look like multicolored boxes about the size of characters.
I tried using the shift key to get to grub and try to boot into recovery mode--no luck. I tried using grub to boot to the previous kernel--no luck. It just sits there at the Ubuntu screen with this weird resolution/appearance.
I can boot from the Live CD and things work fine. I can see the file system, grub files etc. Any help debugging this would be most useful.

I downloaded the latest LTS last evening , placed it along side my Win 7 , things went well seemingly until I got the install done and restarted the pc. From the initial purple log in area, the second I curse to the place to put my pw the screen blinks off to the purple screen, devoid of the login section and freezes, taking my mouse control away and then it just sticks. I have restarted quite a few times with the same issue. Is there a known issue about Win7 and the latest LTS concerning the log in screen?
if so, what would I need to do to correct, do I need to jump backwards to an earlier version and wait for the issues to be corrected? Is that even possible?

I installed Ubuntu 10.10 on my laptop Lenovo T410 and I found a strange behaviour: sometime a part of the screen (small rectangle) freezes and there is no way to unfreeze it. The only way is to shutdown. I cannot use it to work Other colleagues of mine that installed the same Ubuntu version on the same laptop do not have any problem.

I am not sure exactly what is going on, but my ASUS UL30a (X32a) keeps locking up until I press a key, then it seems to resume for a while.
At first I thought it was just the mouse, but I noticed that the screen stops refreshing also. Hitting the space key (or any other key) brings the systme back to life (until it happens again).
It is a fresh install of Ubuntu 10.10, not much seems to be going on in the top list (compiz 1%, xorg 0.5%)
I am looking for ways to try and diagnose the problem (if not fix it )

I was not able to install any version of Ubuntu. Everytime when the splash screen would appear, the computer would freeze and no hard drive activity would be present. The only way was to use the alternate install version of Ubuntu 10.10. Though, the splash screen problem persists. After the Ubuntu boot screen disappears, the splash screen appears with the coursor. About 3 seconds later it becomes unresponsive and the hard drive light stops showing activity. After reading a lot, I think it's my video card driver. I'm a complete newbie, so any commands need to be written out so I can just type in and cross my fingers. I can boot into the GRUB recovery mode. I log in and have a text based setup at this point.You know, I can type sudo commands and all that jazz. How can I fix my video? The graphics is not integrated. It's a 32mb nvidia TNT2 PRO.

i start up the computer, it loads, it arrives to a screen that says the laptops name, and a bar at the bottum. I can interact with this bar, it is blank and has a picture of a little man with a circle. Clicking on this does nothing, another says shutdown and reset, again clicking on it does nothing. I think the error occured when the computer got unplugged while updating.now before we get into all this GRUB and fancy stuff. I am completely new to linux. I installed this using a cd made from an iso image downloaded from the site. I did not use a windows loader. I don't even have windows anymore. I have all my personal information and data on here and would like it to be restored.I googled it and it says to go to recovery mode using GRUB, don't know how and don't know what grub is.:confus ed:

If I close my laptop lid for more than a few seconds, my screen will become completely unresponsive, aside from the cursor. Any idea what could be causing this?

I just upgraded to 11.04. When I rebooted, everything looked normal. When it asked for my login credentials, it froze. I've tried recovery mode during grub selection, but no luck. I want to try 11.04!

I did a fresh install of 11.04 a week ago and I had my screen saver set to run 'Floating Feet' after 15 minutes idle time. Twice I've left my computer, and returned, clicked the mouse, and found my computer frozen on the screen saver. I was able to recover once by hitting the power button, which brought up the shut down/restart options and normal desktop. It hasn't happened since I turned off the screen saver, so I'll just leave it that way until a solution arises.

I've been using Ubuntu 11.04 for some time now and I'm experiencing many severe bugs. One of this is very bothering and I still can't find a solution. I experienced many problems maybe related to this, but seems to have gone away by downgrading xserver-xorg-video-ati. Still anyway, when in dual screen, after some time, the screen completely freezes. The system is completely freezed, I can't even go to a shell, but I noticed it is possible to log in via ssh.
I've never had problems with ATI opensource drivers. Now I even noticed a logout problem anyway (which is known as far as I know). Is there anyone else experiencing the same? I found some others complaining about something similar, but not exactly the same and still no solution. Is it possible to somehow debug this when it happens? I have to note that I'm still using kernel version 2.6.35 because the new 2.6.38 is not booting at all. But I don't know whether this is the problem or not.

I set up a dual boot on my laptop a few days ago, between Windows XP and Ubuntu 9.10 (installed from Live CD). All the hardware is working fine.
Anyway, SOMEtimes, during the splash screen , the screen turns off (physically turns off) and the hard disk seems to stop. I cant do anything appart from force it to power down.
Yet sometimes, it boots up fine.
I want Ubuntu to work first time EVERY time.

I have 2 computers with Ubuntu 10.04, when I VNC to the computer I want to control I get the first frame but no subsequent frames. However I can still control the computers mouse and action on anything I want to but I need to be in the same room to see the screen I am VNC'ing to, this sort of defeats the point of VNC as I would like to be able to control the computer from any room in the house.

I installed 10.04 beta 2, but have all the updates to this point. Everything freezes randomly. I get a weird pattern across the screen and the mouse and keyboard stop working. From what i can tell, the hard drives just keep spinning at whatever speed they were spinning when the freeze occurred.
I haven't been able to reproduce it on purpose.
I was using an Nvidia 8400 GS and through some reading i thought it might be the nvidia drivers. I tried reinstalling the drivers and still froze randomly. I took out the video card but I realized I have an onboard nvidia chip (GeForce 6150SE nForce 430 rev a2). Drivers or not, it still freezes randomly.

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.
