Ubuntu :: Start Over - System Crashes Or Hangs For A While Before Coming Back
Mar 1, 2011
I've been using Ubuntu for quite a while, several years, though several upgrades. Experimented with various things, uninstalled some and various other messy activities. Some things don't work as well as they used to. Sometimes my system crashes, or hangs for a while before coming back. I still get a KDE screen when I shut down, though I attempted to uninstal that desktop. I would like to start over, that is with as little trouble possible to reinstall from scratch. Have to save my user directories, also the directories for my LAMP applications.

If I leave my Macbook Pro 7,1 updating and come back to it a while later and I press a button to turn the screen saver off, it just has has a black screen a cursor in the corner and nothing else. It hasn't automatically rebooted, I know, because I dual boot and it would've booted into OS X. When this happens I can usually press ctrl+alt+F2 or something and I get a command line prompting me to login but if I try and type nothing appears at the login prompt. The only way I can recover from this is to hold down the power button to turn it off.

After opening my laptop again I am getting a message < waking up. Please wait > but then I get again a black screen.

I don't know what I did, but for some reason my fedora system hangs on the OS startup when I use my default kernel. I can still use my other kernel to startup the system though, so it's more of an inconvenience really, but any help fixing it would be appreciated.
The default kernel is Fedora (2.6.34.7-61.fc13.i686) when I start up using this kernel the system hangs(I think I using the right term here, but not sure) after these messages code...

So I just recently switched to Ubuntu because my computer's hard drive with windows died. When I bought a new hard drive, it was just easier to use Ubuntu. Anyway, I really like the operating system so far, and have had no problems except for one: When I close the screen on my laptop, the screen won't come back on when I open it. The buttons on my keyboard light up and everything like they should, but the screen stays black. I have tried doing Ctrl + Alt + F keys with no luck. I am very new to Ubuntu so please go slowly. I am using Ubuntu 10.10 on an HP Pavilion Dv4 laptop.

I recently installed 10.10 netbook remix on my Samsung N150 netbook alongside Windows 7 Starter. At the time of the first installation one of the forward buttons wasn't showing up so I was stuck and had to reboot and restart the installation. This happened after I had made the partition for Ubuntu so when I got back to that stage in installation there was already a partition made. I tried to delete the previous partition but it kept coming back so I made another partition for Ubuntu and installed it.
It was working fine apart from a problem with the right-click and dragging icons. Then I updated the grub and after restarting the machine my grub disappeared and I was left with a black screen with a blinking cursor. I reinstalled Ubuntu again using my external HD with new partitions (the same thing happened where the partitions kept coming back after trying to delete). Now my Windows won't load up and just goes straight to recovery. After I restored it the grub disappeared again.

Everytime I leave the computer for a few minutes the screen goes black (I think in suspended state) and when I move the mouse it asks me for the administrator password. How do I make it so it doesnt ask me for it after coming back from suspended state?

I upgraded my laptop from 10.10 to 11.04 yesterday. On the reboot part of the installation and on all subsequent boots, the loader gets as far as the initial Ubuntu splash screen before switching to verbose mode and dying in interesting ways.
If I boot using wireless, the display flashes six times, then sometimes hangs around before reporting: iwlagn 0000:08:00.0: Aggregation not enabled for tid 0 because load = 4 (this number can be anything from 0 to 10)
If I boot using a network connection, I get the same splash screen and six flashes before the system hands, usually at the message: Stopping userspace bootslash [OK]
I am not keen on reinstalling from CD except as a last resort as I have a number of files that I do not want wiped.

I have been having a problem with the computer I'm using were it keeps freezing (mouse works, however nothing else does). Usually to get out of it I have to use REISUB signal for a forced reboot. This only used to happen once in a while, but was still annoying. Tried a new video card, new motherboard... neither helped. Other Linux OS had the same issue, Windows XP works ok.Yesterday after running a full update it got worse (first since I installed OpenSuse 11.3 64 last weekend). It appears that Firefox will crash X completely. Rendering got slower and Compiz disabled (not a big deal). Opera also crashes and just by resizing a window or scrolling down on gedit also do the same. I found a few errors on my /var/log/messages log, looks like it's related to the driver that I'm using (noveau). I'm pretty good with Linux, but when it comes to X is the same as speaking another language to me! :-S
Code:
Aug 27 19:06:42 opensuse polkitd(authority=local): Registered Authentication Agent for session /org/freedesktop/ConsoleKit/Session3 (system bus name :1.72 [/usr/lib/polkit-gnome/polkit-gnome-

I have "successfully" installed both LinuxMint 9 "Isadora" and Ubuntu 10.04 on it, and found I have the same problem with each. That is, I am able to:
1. startup to the live CD
2. format the hd to be all Linux
3. startup the computer from the HD into Linux
Then, I get these problems, in both distributions
4. Monitor hangs on the desktop background for an immensely long time (maybe 30 minutes?) with no cursor or menu bar or status bar or anything
5. Eventually, I get a desktop that I would expect and I have an option to do things like update, customize etc. however at this point, the cursor is invisibile. I am able to navigate and get around by guessing (menubar elements highlight when being hovered over)
6. After about a half an hour in an operable mode (I have tested network connections, played videos and music from external HD media stores, you name it.) the monitor will mysteriously crash.
Clarification:
#4: nothing I do while the dekstop background is featureless, meaning any key on the keyboard or any normal key combination, including all the F keys, ctrl-F keys, ctrl-alt-delete or ctrl-alt-escape or alt-opt-delete or alt-option-escape etc. Nothing does anything. It is utterly unresponsive.
#6 What I mean by "mysteriously crash"? the monitor goes black and then the top half starts displaying what looks like a super-zoomed in bar code. The only way out of this is to force the computer to restart.
Since this happens in both the linux distributions, I'm at a loss to figure what's causing it.
I am using a Compaq FS7600 17 inch CRT monitor with this Dell Dimension 2400.

After I updated the Ubuntu on my Lenovo S10 netbook from 10.04 to 10.10 Firefox crashes when I try to open it. I tried uninstalling it and installing it again (with the add / remove software function) so I thought I would have a "plug-in free" Firefox - but it still crashes. At the moment I am using Chromium - but I want Firefox back - so what do I do ?

I am experiencing frequent crashes for my browsers (FireFox, Opera, Konquerer). It doesn't seem to be related to the amount of tabs I have open, sometimes it will crash on 1 tab, and sometimes it is fine to have 20 tabs up. In addition to this, some flash videos hang after 3 secs.
PC spec:
OS: SuSE 11.2 (x86_64)
GUI : XFCE (KDE 4.0 back up)

I did an adjustment or two, and then it has been just been hanging up using 100% CPU when it is loaded. When an application uses it to save a document, it does not hang.I created a Templates folder and assigned it with the user-dirs.I then changed the view of that particular directory from LIST to ICONS.And then it started to hang up.Somehow I was able to change the view back to LIST, but it still hangs up.

I'm within Firefox and start playing ..... movies Firefox crashes. Thats not the worst of it however; the process locks up the whole system and I have to reboot. I attempt the kill it with now luck. Killing the PPID doesn't help because it got to 1. I even looked a pstree to kill parent processes without any luck. I'm like WTF. Firefox crushes with the "ZL" in the line when running the ps command also. I'm going to uninstall Adobe flash and reinstall it to see if that helps at all. This is the only time I have every had this type of issue.

A USB hard drive is used as backup drive.
When it is not plugged in, the system boots without any issues.
When it is plugged in, this hangs to the point I have to unplug the CPU.

I'm running F 13 and today's updates included updates to Xorg, so I logged out and back in to let them take effect. Ever since then, Firefox has been repeatedly crashing, especially on certain sites. I managed to get the crash reporting tool to report it to Bugzilla, but when I try to go back to add the bug report to this post, Firefox crashes, every single time. Has anybody else found this? If somebody can get to bugzilla.redhat.com and find the report (The email address I use there is joe@zeff.us if it helps.) I'd appreciate having it added as a response to this, so that others can find it and,

My computer works well, but when I try to shut it down or take a re-start it hangs.I need to use the power button to shut it completely down. The thing is, or I think it is, it tries to terminate "bluetooth", problem is I dont have BT on this computer. Is this the reason ? It shows " - Terminating bluetooth" on the shut-down screen. And another thing, sometimes the launch-bar dont auto-hide when my computer has been on for � while. I need to log out and in before it hides?

I am using Ubuntu 11.04 and it hangs as soon as I start to enter my password on the login screen. The way I am currently booting up is using failsafeX which is leading to no sound on my laptop.
I tried deleting .gconf/.gconfd/.gnome2_private/.gnome2 folders and it didn't help
This is the output to the lshw command: [URL]
I put this up since I have no sound on my system in ubuntu ( no effects mode ) and now even on Windows there is no sound (strange)
I also tried deleting the /config/autostart/* files and it didn't help.

I am getting mad about 10.10. Nothing is working as it should work!
Sound... Ok, system sounds is working. Amarok is working. But it doesn't work in VLC, flash, etc. GNOME: works, but only starts working, when sound is changed.
(No idea, but KCMInit always crashes at start (segm fault)).
What I supposed to do?

I have installed mythbuntu 10.04. It worked well for a few days. Now my frontend does not start or crashes just after booting. You can see the frontend background for a few seconds but the menu does not load. After that, the mythtv window disappears and you can see the ubuntu desktop. Here are the last few lines from the log file:
