Ubuntu :: 10.04 Crashing On Shutdown / What Causing This?
Oct 19, 2010
I had this problem in 10.04 and hoped it would go away in 10.10, but it did not. My computer crashes on shutdown. When the system is shutting down, the screen goes black (sometimes with a bunch of grey lines), and just hangs. I have waited for a long time but nothing happens. I have to shut it down manually, with file losses as a result. How should I go about fixing this? I have looked a bit in /var/log but do not know where to look for. Where can I find what is causing this?

I just installed Ubuntu 10.10 64bit. I installed VirtualBox ( AMD64 bit version) from here [URL] however whenever I went to run it, it would cause the system to log out (not shut down, just drop out) and return to the login screen. I thought this could be an issue with that version of VirtualBox so I uninstalled and and then installed the version through the Software Centre, however unfortunately it was causing the same problem. I thought this may be a VirtualBox specific issue, however the same thing is now happening since I installed skype (again only when I run Skype).
I understand the description I am giving is very vague, and as such my first question would be : how am I able to produce an error report (of such) that would better suffice in describing the problem? Obviously, if anyone has come across this problem, do they know how to fix it? Sorry, one last thing, and I'm not sure if this matters at all, but I'm running three monitors over two video cards using the Nvidia driver with Xinerema. I only bring this up, because a while back I was running 10.04 with two monitors in Twinview and had no problems.

i just wanted to check if its something silly ive overseen and if anyone else is having this problem...im running Ubuntu 10.04.2 LTS with latest version of squid 2.7.STABLE7-1ubuntu12.2. now when i shutdown or reboot the system, it says something along this lines of umount: /var is busy (check using lsof...). this is followed by text in red: [fail].when the system starts up again, i can see /var journal is recovering, so the /var partition was not cleanly unmounted during shutdown. obviously, there is a risk of filesystem corruption here. FYI, i have /var and other important mountpoints as separate partitions (LVM; ext4).
to confirm my suspicions of squid still running during shutdown, i checked /var/log/squid/cache.log and there is no indication that it received the signal to terminate. if i manually run "stop squid", then cache.log would show that squid has stopped successfully (or words to that effect).to confirm that /var is locked by squid during shutdown, ive added a script to run "lsof | grep var" before filesystems are unmounted. and voila! it indicates that various files used by squid in /var such as swap.state are still open. hence, the next system startup would result in /var recovering journal again.finally, i tried running "stop squid" before issuing the shutdown command and it successfully unmounts /var and i do not get /var recovering journal on the next system startup.

I have been looking for a lightweight bandwidth monitoring app and came across bmon. It does what I need. However it has an interesting way of exiting.
when it is running and you close it down it ask you 'Really quit (y/n)' and does not shut down. I am used to just right clicking on my desktop and selecting 'leave' when it comes to shutdown time.
A few times now the laptop hangs on shutdown if bmon is open. I guess it is due to the app asking if it should shutdown. Is there a way to disable the app asking or alternatively nuke it for sure with some script on shutdown.
I could search the relevant konsole running the app and go thru the steps to shut it down but sometimes I am in a hurry and it doesn't feel like the way to go anyhow?

I have installed a cluster computer with 10 nodes . The manufacturer is HP . All nodes and the master node have redhat enterprise linux installed in them . When I shutdown the nodes from the master terminal using "shutdown -h now" they get shutdown . But they dont get completely turned off . This issue bothers me when the power supply is given , all nodes boot up simultaneously generating a huge heat .
Thing to note : When we shutdown our PC they get completely turned off . When the power supply is given , a press on the Power On button is required to boot the system. But , why does it not happpen in the case of cluster? Is there any other way of completely turning off the nodes from the master terminal ?

Recently I installed vncserver (tigervnc) on my desktop. Ever since my computer refuses to shutdown normally. At shutdown the following message pops up: Quote: System policy prevents stopping the system when other users are logged in Then I have to enter the root password to shutdown. If I stop vncserver before, the computer shuts down normally.

Ubuntu will randomly pop up the shutdown menu and then shutdown.It seems to happen when im in firefox and typing and it has been difficult to replicate. I dont think it is a temp issue since watch sensors shows temmp of 40-50C. Someimtes it happens every minute someimtes i can go 10min without it happening.

I cannot locate shutdown log for Linux shutdown to check various activities carried out during shutdown. I can view Startup Log which is availble on console>Applications>System Tools>System Logs.
I have included Shutdown/Startup in dbora, so that Oracle 10gR2 Shutdown/Startup will be automated during OS Shutdown/Startup.
I want to check Shutdown log because Oracle Shutdown was not running, as from $ORACLE_HOME/shutdown.log contains no entries, where as startup log contains latest startup details.
That means here 2 issues are there. One, I want to locate OS Shutdown Log and the other being Why Oracle Shutdown not getting executed.

i recently switched from windows vista to ubuntu 10.04, so i am a complete noob at this stuff... i enabled the ufw a few days ago and ever since then my Internet connection has been pretty spotty. i connect to the wireless network fine, and there is nothing wrong with the actual Internet connection (other computers in the house are using it fine) it is very frustrating and i was wondering if there is a way to stop this, do i need to forward some ports, or do i really even need the firewall at all... i don't really do many things that would allow me to get hacked in the first place..

Is anyone else having trouble with frequent kernel panics whenever the Transmission bittorrent client is running? I get them after about 1-2 minutes of having transmission running, and need to do a hard reset. I didn't restart transmission this last time and it has been almost 10 minutes with no problems. I've been having problems left and right with KPs since around 8.04 but previously they were infrequent enough that it was still more convenient than using windows...Every 2 minutes is ridiculous though, if I can't fix it I'm going to need to get another torrent client!

I'm only relatively new to ubuntu and am having a problem with firefox. There was an update waiting for me this morning to install some dummy package and since I've done that firefox falls down whenever I try to go to a page that requires flash. The screen turns grey and nothing happens.
With my limited knowledge (and inability to use any page that requires flash) I've tried to remove and re-install flash but nothing I do seems to work

I recently upgraded to 10.04 and now netbeans is not working. It worked fine the first restart after i upgraded so i thought all was good. This morning i ran it and it said something about not being able to load some modules. Since then, i've tried uninstalling it, re-installing it, and numerous restarts, all to no avail. I'm gonna try downloading the package from their website and running it from a separate install and see if that helps, but after that, I'm out of ideas.
When i run it either from the terminal or by clicking on it, it shows the loading screen, then the loading screen dissapears, then nothing else happens. In the terminal, it waits about ten seconds after the screen dissapears and the program seems to exit, since the terminal begins accepting commands once again.

I'm running firefox 3.6.12 with the following add ons installed: Windows Media Player 10, Div X web player 1.4.0.233 and Flash 10.1 r102. Ubuntu is 32 bit as is the Flash plugin. Quicktime, VLC and iTunes application detector are installed but disabled. I get recurrent episodes whilst using firefox where the entire screen goes grey/black and after a minute or so the login screen appears and I have to enter my password get back to the desktop. I suspect that this is flash related as it normally occurs after watching a few minutes of video. Disabling flash reduces the frequency of the problem but does not eliminate it.

Running a clean install of Ubuntu 10.10 under VMWare Player on a Thinkpad with Win7. Have previously used Perl/TK for GUI apps to run under both Windows & Linux. Latest Activestate Perl (Windows) does not support Perl/Tk, recommends Tkx, so I wanted to see if Tkx would work under Ubuntu. Tried to install Tkx using cpan, got obscure failure indicating dependency problem. Found a recommendation to apt-get install tcl8.5-dev, and then cpan installed Tkx.
Note, perl 5.10.1 is installed in Maverick by default. apt-get upgrade says I have the latest perl, Tcl and TK. I installed Tkx version 1.09 (using cpan). Couldn't find any info on what perl / Tkx versions are compatible. Now Tkx is installed, but any attempt to run a script that uses Tkx causes a segmentation fault. apt-get installed pmtools to investigate. Even examining Tkx with pmtools can cause a seg fault, for example:
$ pmvers Tkx
Segmentation fault
Is Tkx known to work (or not work) under Ubuntu,version 10.10 or other versions? Any suggestions about what to try next?It's hard to find info about Perl Tkx because so many people put "Can u help, tkx in advance" or similar in postings about anything under the sun. I've read a lot of them.

i've noticed lately that when scrolling, the video "tears" and moves along with my scrolling on sites such as videos, when it should be fixed in position. note that it doesn't actually move perfectly and is flickery/cropped while scrolling. i have all the latest updates (10.10) and notice it in both chromium and firefox, so it's either the window manager or ati driver.

BlizzPlanet reports that people are seeing their nvidia graphics cards overheat when running the Windows 196.75 driver and playing 3D games. I have to wonder whether I fell afoul of this issue. A week ago I installed the 195.36 nVidia proprietary Linux driver on my Karmic Koala system, after adding the PPD nvidia-vdpau repository to my sources.list. I restarted so the new driver would take effect... and was surprised to see the graphics chip temperature soar to over 130 degrees Celsius. It fried itself. When I opened up the case, I checked the card's fan, and it spun freely, and I'd not heard any noise of the sort that accompanies a dying fan. I'm sticking with 190.53 for now. Has anyone else seen overheating difficulties with the 195.36 driver?

I'm having a problem with the oci8 module in PHP. I have been running this server for over a year with this configuration and never had an issue... I had been away since last Thursday, and suddenly this started happening this morning. I'm the only one who has server access, which has me baffled.
I've narrowed it down to the oci8 module because:
* I created a PHP script that does nothing except call oci_login(), which seg faults.
* Any web page that uses the oci functions fails... it asks you to download the PHP file, which is empty (likely because the oci_login call done before anything in PHP is printed).

I got a new X201 which is running Ubuntu 10.04. While at home, everything is fine, at work, I encounter some issues with wireless. the signal cuts in and out repeatedly.Here's the output of ping. I set it to ping a server every 90 seconds, 10 times. So this is a snapshot of 15 minutes of network activity...
Code:
PING (REDACTED) bytes of data.
64 bytes from (REDACTED): icmp_seq=1 ttl=252 time=1.50 ms
64 bytes from (REDACTED): icmp_seq=2 ttl=252 time=2.13 ms
64 bytes from (REDACTED): icmp_seq=3 ttl=252 time=1.38 ms
[code]....
Also I tried this (from a 2 year old thread which was most relevant solution I could find):
Code:
Changing AVAHI_DAEMON_DETECT_LOCAL=1 to AVAHI_DAEMON_DETECT_LOCAL=0 in /etc/default/avahi-daemon has got rid of the irritating pop-up. Basically, every 5 minutes or so, for a solid 60 seconds or so I get no signal. I've tried updating the kernel, and doing apt-get remove avant-daemon, but still have problems.

I'd been using karmic for ages with no probs. I did a fresh install of lucid when it came out and installed compiz and cairo-dock. Rather annoyingly my computer started to completely freeze. I couldn't get a shell up, I couldn't ssh from another machine and the sysrq keys didn't work (the fan picked up speed almost immediately). The freezing didn't seem to follow any pattern and wasn't happening when accessing the dock. I decided to disable compiz (and cairo-dock) to see if this helped. It did! I reintroduced compiz with no problems, but as soon as I introduced cairo-dock, I started to get the same problem.
I've not been able to find anything in the general logs to give any clues. ubuntu lucid

I have an intermittent and very irritating problem. I have a desktop PC with Ubuntu Lucid installed that I use primarily for watching films using VLC. Every so often (seemingly at random) around half way through the film the whole thing locks up - the video freezes, the audio skips (like a stuck record) and the system is unresponsive - the only cure is a full restart with the power button. Im at a loss as to how to try and diagnose this issue. Is there a log somewhere that might have the info after I reboot?
Usefull info on the system:
- AMD processor - 64 capable but running 32 as I wanted to avoid issues.
- grpahics is via an NVIDIA Geforce FX5500 (PCI interface NOT AGP)
- Restricted NVIDIA drivers installed and working
- Also useful to note that this problem occured when using an AGP ATI Radeon 9200 (using the standard open source drivers of course). In fact the problem was worse with the ATI - the frequency of lock ups is less with the new set up.

I'm running Ubuntu 11.04 and I'm really new to linux. My problem is that whenever I try to browse a site I notice the website loads very slowly because it takes a long time to do lookups. I installed Ubuntu with an onboard NIC and later switched to a PCI NIC (Dlink DGE-530T). Although I disabled the onboard NIC in the BIOS, it doesn't help. Could this conflict in configuration be a problem? My download rates are fine, its just lookups that take really long ( upto ~ 10 seconds). I know the PCI network card is fine because when I jump to Windows 7, lookups are normal again (~ 300ms). At first I thought about installing the sk98lin drivers for the PCI NIC but I saw a couple of places where people have mentioned that the skge driver that comes along with the kernel is better.
I have tried a system wide as well as Firefox disable of IPv6. Here is my /etc/udev/rules.d/70-persistent-net.rules
Code:
# PCI device 0x1186:0x4b01 (skge)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:24:01:14:eb:39", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x10de:0x0373 (forcedeth)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:8c:3e:19:ed", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
The interface I want to use according to the listing above is the one with the MAC - 00:24:01:14:eb:39.
I tried removing one of the entries in the file above and rebooting but it still didn't work. Here is a look at my /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.10
gateway 192.168.1.1
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
