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
View 2 RepliesI 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'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.
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.

View 9 Replies View RelatedThe 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?

View 4 Replies View RelatedI recently learned that you can upgrade your version without downloading and burning a cd. So I upgraded from 10.04 to 11.04 and now can not use my computer. It will boot up display the log in screen and I can log in. But when it loads up as soon as I try and do anything the computer will completely freeze. I am not really sure what is going on. I do have a somewhat older machine but I have above the minimum requirements to run 11.04 so I was wondering if anyone else has had this problem. Also I can easily boot into the 10.04 cd so I would like to know the path to back up all my documents and photos just in case I need to reinstall the older os.

View 2 Replies View RelatedI noticed that after making my build in suse studio my system freezes immediately after GRUB ( Normal or Failsafe) boot splash screen. I also noticed that this happens only with the specified kernel below. I'm not sure when using Kernel 2.6.37, one had the same problem. I never used it. The original kernel 2.6.34 had no problems such as the one I have described. My systems has no further problems only that it takes several restarts to go past the "Freeze". Below is a list of my system specs:
openSUSE 11.3
Kernel-pae 2.6.38.2-4.1 from Kernel Stable.
GRUB 0.97-174.1 from openSUSE 11.4
Upstart 0.6.5-33.1
xorg-x11-server 7.6_1.9.3-142.1 from X11:xorg 11.3 repo.
The GRUB from openSUSE 11.4 has been very stable and non-problematic. I will be buying an Intel core i5-2500K in a few months that's why I need the latest kernel and XOrg-X11-server. What could be causing the freezing?
I'd like to install Fedora 14 64bit as a dual boot on an existing win 7 32bit system. When I boot with the Live CD, after selecting "boot" in the Fedora boot selection menu, I get a grey screen with a white cursor, and the system freezes. I checked the Live CD on my laptop and it worked perfectly.
My System:
MotherboardASUS P5Q DELUXE
CPUIntel Core 2 Duo E6750, 2,66 GHz, Sockel 775

I actually have it installed on two of my computers. One is an older Acer Aspire 3100 that dual-boots windows 7 and Ubuntu 11.04, and an Acer Aspire ONE that has Ubuntu 11.04 as main OS. Before Ubuntu, (even currently) I'm a MAC user, and i'm really liking Ubuntu. On my 3100 it works just fine except the screen flicker on wake, but a quick reboot will solve that.
On my Aspire ONE i've had to re-install ubuntu multiple times. (we're talking 5 or 6 in the last month) Sometimes, it'll boot up to absolutely nothing. One time I got a weird error message everytime it booted. The last install froze up a lot, and eventually would only start to boot into setup. I reinstalled Ubuntu, again and it worked until I shut it off. Boot back up, same thing. Threw me right into setup. I was able to get around it after 5 or so tries of rebooting, hitting ALT F11 and somehow got into ubuntu recovery, but loaded normally. I'm using it now and it's working great currently.
Specs on the ONE
1.5GB Ram
8GB SSD (could this be the culprit?)
ATOM (1.8 or 1.6) GHz Processor.
Halfway through this fiasco, I put windows XP on it and used it solid for 3 days without any of the mentioned above issues.
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've got a desktop 10.04 LTS installation working nicely, and leave it logged in processing things for me. I log in remotely and don't always leave the screen plugged into the computer. Trouble is when I reboot it without the screen plugged in it will sometimes boot to a command prompt.If I turn it off, plug in the screen and turn it on again I get into the GUI as normal. I can't see any settings to change this behavior - what am I missing?
View 1 Replies View RelatedSomething plagues my Ubuntu box since I upgraded to Ubuntu 10.10 - I end up with a blank screen while booting. I use an Asus F81SE Notebook, and Dual Boot with Windows XP. Everything worked fine with Ubuntu 10.04.
When I start my notebook after the upgrade to Ubuntu 10.10, I come to Grub, and when I select the latest kernel available, the hard disk LED blinks for a second, turns off ... and nothing happens any more. There is just a blinking text cursor.
As I upgraded from the previous Ubuntu version, there was an older kernel left (2.6.32-26-generic), which boots up fine.
I run 64 Bit on an Intel T4200 CPU. Booting the Live CD brings me to the purple screen with the open source logo at the bottom. I tried 32 Bit and 64 Bit versions of Ubuntu 10.10.
I don't seem to find similar problems on this forum. But does anyone know how to find the mistake?
I installed Lucid Lynx to a Gateway Solo Pro 9300(600 Mhz/224 M) and everything looked normal on the display with cursor,icons and abatross background. I rebooted and I have a blank screen with only a cursor showing. I don't think it is a video card problem because I had a normal display upon installation. Is there a way, on boot, to get into a diagnostic mode? what should I look for in the diagnostic mode?
View 4 Replies View RelatedI just set up a ubuntu 11.04 Desktop 32-bit installation on an older pc that I found in the basement. It was running xp before and had 2 hard drives so I left the xp install alone and installed ubuntu on the second hard drive. It all booted up and worked fine until I rebooted it for the 2nd or 3rd time, now after I select ubuntu from grub it just loads to a black screen. Even in recovery mode if flashes the text across the screen and then also goes to a black screen. Now what seemed really wierd is that the same thing occurs if I try to boot from the usb drive i used to install it the first time, but win xp boots fine.

View 7 Replies View RelatedAbout 1/2 - 3/4 of the times I boot my PC to 10.04 RC, It quickly goes into a white screen at the beginning and then just hangs there. I updated from 9.1 and it did this, then I fresh installed and had same issue, including when I tried to boot of the 10.04RC boot CD (before 10.04 was even installed). There is nothing listed under sys/admin/hardware. In all cases, I have to hold power button, and keep rebooting...eventually, it will boot normally.

View 8 Replies View RelatedSo I've been using Ubuntu for about a month now. Everything is great and all but today when I booted into Ubuntu everything was going well--the splash screen appeared and the dots were doing their thing and all--but then there was just a blank screen. Some people have had this problem after a fresh install of Lucid, but its been working for a while so I don't get why it isn't working... I didn't do anything to the system except run some updates before I turned off the computer.

View 1 Replies View RelatedI am a complete Linux newbie and I tried installing the latest release candidate (10.04) as a dual boot with Windows XP. The install seemed to go fine and it said it needed to reboot to finish the install. It rebooted and then displayed a series of errors on a DOS-like screen (which I wish I wrote down). When I realized that it was definitely hung, I then held the power button to shut it off. After that, all it does is boot to up to a blank/black screen with a cursor.The box is old and I was actually going to throw it away, but I figured this was a good opportunity to give Linux a try. At this point, I'm willing to go to either Windows or Ubuntu... I don't really care which. I actually just want to recover some files on the box
View 7 Replies View RelatedI'm using Ubuntu 10.04 64-bit, which is installed to a second hard drive on my desktop. Earlier this afternoon, there were two 10 second power outages in my neighborhood. The first caused the system to restart with no effect, but after the second outage Ubuntu no longer boots properly. The problem is this: When I boot, I get to the grub screen. I have tried choosing four different options (the most recent kernel, a slightly older kernel, and the recovery mode of each). For each, kernel begins loading, but at a certain point the input to the monitor dries up, and after a few seconds the monitor enters standby mode. When I boot into recovery mood, the last message I see before the screen goes blank includes "udev starting version 151" followed by three lines that read "assuming [something that I can't read before the screen goes blank]." The computer itself remains on, but I have no way of knowing exactly what it is doing.
There seems to be no hardware damage as I can boat into Vista, and I can also boot into 10.04 from a USB. I've used fsck to check the partitions on my hard drive and the test came up clean for all of them. Since I only installed 10.04 a week ago, I could just copy the handful of useful files I have to my external drive and re-install, but I'd like to get some experience troubleshooting this problem. My first assumption is some kind of problem with the video drivers or GUI.
after spending more than 48 hours watching the install bar creep along, it has finally finished! but when i boot up my ibook it gos to a black screen and nothing happens.
