I have a very weird issue here. At work I have a machine that runs ubuntu 10.04.1 and whenever I do a "shutdown -h now" the system shutsdown for a few seconds and the comes back up again.
The system itself is a HP DC7900 SFF machine. It was the network setup along with wild flying magic packages that caused this.
I am unable to shutdown the ubuntu system properly. As i click the logout button, the desktop icons and taskbar and everything disappears and only i can see the wall paper... Then i hav to do a hard shutdown by pressing the power button...
View 2 Replies View RelatedI have an mysql innodb ~ 20gigs. Normally shutting down mysql (service mysql stop) takes a few seconds. When I reboot Ubuntu with the reboot or shutdown command it just reboots it super fast without mysql logging (/usr/sbin/mysqld: Shutdown complete) Also during this shutdown the following is failed: umount2: device or resource busy /data: device is busy.
mysql is setup to read from /data . Why is ubuntu not waiting for mysql to properly shutdown before unmounting the filesystem and rebooting?
I just installed apt-get hibernate and when my computer shuts down, it will go to a recovery menu. I have to end up killing the machine.
Also when I try to hibernate the machine this error msg will appear: hibernate:Warning: Tuxonice binary signature file not found.
How should I rectify this error?
I'm sure there's an underlying hardware problem for this... but I figured I'd start here as I do not know the specific hardware issue.
I'm in Ubuntu 9.10 (Ubuntu Studio actually) and my computer will not shut down properly. I get the splash, then a black screen, then something like #terminating processes, #closing connections, #blah blah blah, #will now halt(or will now restart if rebooting)
I have noticed my server do not shutdown properly sometimes.It should do it with this command in a cron with root session /sbin/shutdown -h now
View 3 Replies View RelatedThe startup and shutdown displays are a series of vertical black and white lines, and the text displayed on them appears as more or less white blobs. Otherwise, the displays when 11.04 is running are fine, but this startup looks so naff it would be nice to change it so that the diplays can be read. I would hate to demonstrate Ubuntu to someone and have to explain such a display.
View 7 Replies View RelatedI have an user space application that performs file I/O operations, when a SIGKILL is captured, some routines are done first to ensure that all I/O operations are completed before rebooting the application or system. My question is, this won't work if the power button is pressed or the power supply is disconnected, so there can be incomplete I/O operation or corrupted data written into the file, so is there a way to prevent data corruption or at least complete any ongoing operation when this scenario happens? Assuming there is at most 1 second before the power really went out, can I/O be still completed?' I'm running the application on a busybox 2.6.14 kernel on an embedded system board.

Now we have Jessie as stable, yet LXDE doesn't shutdown properly:
On the same computers, Wheezy LXDE shut down very fast
I installed Jessie from the netinstall image.
On a 2007 computer, it's like the old days with a Pentium II running some version of Puppy Linux or Slitaz. The system shuts down after a while but the computer remains on.
On a 2013 laptop, I added the line init=/bin/systemd in the Grub default file as advised on the old thread above. The laptop shuts down after a while, the system first, then the hard disk goes to sleep, then all the leds are off.
If I run the magic command, the computer shutdowns in a breeze, perhaps even quicker than good old Wheezy:
Code: Select all# systemctl poweroff
Now, is this still a systemd bug? Doesn't look like it since the systemctl command works. Is it an LXDE bug? Looks like it in a way - if the LXDE shutdown button enabled the systemctl poweroff command, I suppose the button would work?
Is there a way to make the LXDE shutdown button run the systemctl poweroff command?
I'm glad Wheezy is still with us because I wouldn't install Jessie for newbies — they'd think shutdown (through clicking on a button) is even worse than in Windows.
When i use the shutdown-command in the terminal as root, it nearly works. It starts to shut down, and it looks like all programs and the kernels shuts down. I end up with a black screen, sometimes with the ubuntu-logo on, but it never powers off. I have to force it off by holding the power button. When i use the graphical interface to shut it down, it works perfectly. The poweroff-command works without problem too.
Here is the command i use:

I installed Mythbuntu 9.04 about 9 months to a year ago and (for the most part) I haven't had any problems with mythwelcome, automatic shutdown or the system clock. The "for the most part" relates to the fact that the clock on mythbuntu has always been 4 minutes fast. Then, just last week, the system started acting up - for some reason the system clock changed to 8-10 minutes fast (6 minutes faster than it was previously). To fix this problem, I have tried manually setting the "time and date" setting, and I have also tried setting the "time and date" setting to sync with an internet server. Lastly, I tried changing the system time through the motherboard bios. In each situation, mythwelcome would initially start up with the correct time. Then, several seconds later, the time shown in mythwelcome would change to being 4 minutes fast (as I described above). The time would also be 4 minutes fast when I enter the frontend.
I was willing to live with this, but the weird part is that when I start the system now (assuming I don't have any programs scheduled to record), mythwelcome boots up fine and I see the indication that "MythTV is idel and will shutdown in XXX seconds". Then, it flashes to "MythTV is idle" - like it used to; except now, it doesn't flash back to the countdown for shutting down mythtv. One time when I started the system when I was adjusting the time as mentioned above, I noticed that mythwelcome went to the "MythTV is idle" around the same time it changed the clock to 4 minutes fast - I think there is definitely a correlation here.
I checked out all the settings and nothing else has been changed that would otherwise affect MythTV from shutting itself down. The other interesting part is that I can get the shutdown countdown back if I go to "Utilities / Setup", "Setup", and "Mythbuntu". In the popup screen I choose "MythTV Configuration" and select "Launch MythTV Setup". I get a popup box that says that the mythbackend must be closed (as expected). Then I immediately exit mythtv-setup and the system runs "mythfilldatabase". I exit the Mythbuntu Control Centre and exit the frontend. When I get back to mythwelcome, the shutdown countdown comes back.
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 ?
when my pc boots and shuts down my monitor goes into 'input out of range' mode for a bit between the gui and the text only phases of boot/shutdown.is there a way to fix this? or where to start troubleshooting?also, when it shuts down it hangs after coming back to the text only part

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.

I did a live upgrade from 11.3 KDE and observe a following issue.When I press the shutdown button on the laptop it initiates the shutdown and shuts down fine but after a significant delay of time (something like 30 seconds). When I click the shutdown button in KDE it initiates the shutdown instantly. This was not the case in 11.3 where the shutdown worked the same regardless of the method that triggered it

Further to this LQ thread which Tinkster solved by suggesting the last command (thanks Tinkster) I have been exploring last -x reboot and have found that the reported duration is incorrect for the last reboot and shutdown when a old wtmp file is used. Not having a record for the following shutdown, last assumes that the system has been up until the current time and similarly for the shutdown.
The output comes in time order, latest first, each line showing the time of the reboot and the uptime from then to shutdown. Using last -x reboot shutdown to show the shutdown time, here's an illustration
Code:
shutdown system down 2.6.29.6-smp Sun Mar 7 15:35 - 03:02 (11:27)
reboot system boot 2.6.29.6-smp Sun Mar 7 09:35 (05:59)
09:35 until 15:35 is 05:59.
When the uptime exceeds 24 hours it is shown as (<days>+<hours:minutes) like this
Code:
shutdown system down 2.6.29.6-smp Sun Feb 21 12:39 - 13:20 (00:40)
reboot system boot 2.6.29.6-smp Sat Feb 20 09:39 (1+02:59)
09:39 until 12:39 the next day is 1 day 02:59.
The time in parentheses at the end of the shutdown lines is normally the time until the next shutdown.
So far so good. The incorrect output is for the last reboot and shutdown of an old wtmp file. Here's the output of last /var/log/wtmp -x reboot shutdown; last -f /var/log/wtmp.1 -x reboot shutdown
Code:
[snip]
reboot system boot 2.6.29.6-smp Fri Mar 12 07:42 (01:54)
shutdown system down 2.6.29.6-smp Fri Mar 12 01:31 - 09:37 (08:05)
wtmp begins Thu Mar 11 08:25:26 2010
[snip]
reboot system boot 2.6.29.6-smp Wed Mar 10 14:12 (15+01:42)
shutdown system down 2.6.29.6-smp Wed Mar 10 12:41 - 15:54 (15+03:13)
[snip]
The boot started at "Wed Mar 10 14:12" which had an actual uptime of 1 day 11:20 is reported as 15 days 03:13 which is the time from then until the last -f /var/log/wtmp.1 -x reboot shutdown command was issued. The time from shutdown to shutdown is similarly affected.
I'm new to Ubuntu and have spent several days trying to make a few simple alterations to my Myth 9.10 installation. My biggest task was to get the MCE "power" and "start" buttons working, which they now are - sort of.
The problem is with the shutdown command that the power button activates seems to be different to the shutdown command from the taskbar shutdown menu i.e. when I switch off the computer with the remote it restarts with the "recovery" menu as it wasn't shutdown properly. Same thing happens with the shutdown command from a terminal window. Shutting off from the desktop menu is fine.
can anyone tell me the difference between "sudo shutdown now" and "sudo shutdown 0"
i know that "sudo shutdown 0" will shutdown the system in 0 seconds. but when i run sudo shutdown now my system goes into the maintenance mode?? what is maintenance mode??

View 5 Replies View RelatedDue to some prior issues which I believe to be self inflicted I decided to wipe my system and start fresh. My fresh install appeared to do the trick for a day or two but after running the update manager recently I found myself in trouble. When starting up I receive the message Kernel panic - not syncing: Attempted to kill init! Nothing seems to jog the computer from this black screen except shutting off the power. I've read through some threads of people having similar issues but can't quite figure out what I need to do. I have a Nvidia graphics card which has popped up as a potential problem, too, but not sure if it is my problem or not.
Here is a little history that may or may not be relevant. I'll try to make it brief. My original install was Ubuntu 9.10 Karmic Koala which always worked great. I upgraded to 10.04 Lucid Lynx (through update manager) when it was available and it too worked great until I tried installing a program one day forgetting that I had the update manager running already running as well. The computer didn't seem to like this and never worked well after, thus, leading me to wipe and start fresh. What's odd to me is that I had made a CD for 10.04 from the Ubuntu website as well as the one I had for 9.10 but I could never get it to work when I needed help. I always have to revert back to the Karmic disc when I want boot help. If I put the 10.04 disc in whatever issue I'm having surfaces just the same. Is this because I didn't originally install from that disc?
here is the promised boot script. FYI, I ran it today 2/16/11. I guess the date is incorrect because I'm running the system from the CD.

I have a Lenovo W500 ThinkPad. It is running XP on first partition, then Ubuntu. I've tried both 10.10, 11.04 beta 2, and now 11.04 release.With the release I just installed, it seemed OK till reboot-after-install, at which point nothing came up. I rebooted several times and just got errors and kernel panics in the ATI video driver. I also saw a lot of these messages:"udevd[80]: worker [XXX] did not accept message -1 (Connection refused), kill it" URL...
I had download updates on, I'm trying again with a clean install without updates. (Although, I said don't download while installing, and it says it is downloading language packs...?)Now, I also had issues with 10.10, where it would intermittently boot and fail to get video, I'd just be at a tty, and have to reboot and try again. I found it usually got video if I had just booted Windows (XP Pro SP3) beforehand, and not otherwise So what's going on there? Something up with the actual video card? I want to run Gnome anyways, is there a way I can specify that during the install?At any rate, if I can't get 11.04 working properly, I'll have to run 10.10, which I didn't want to do. I'm starting from scratch and wish to start from 11.04 if at all possible.
So yesterday I upgraded to 11.04 from 10.10 and now when I enter Ubuntu only my background image appears. No files, programs, or anything. It worked right after it rebooted to finish the upgrade but when I turned my computer on this morning I got nothing but background.
