Two or three times on a daily basis it just freezes and I do not know why. For example, I am doing some minor coding, surfing the web and just some regular stuff and suddenly, out of nowhere, it just freezes. I cannot force reboot, cannot shutdown, cannot run, cannot enter terminal, nothing. Totally helpless. Only physical reboot do the work. Never had this issue before.
View 9 RepliesIs there a command i can enter into the terminal or over an SSH session to make an Ubuntu system reboot a few hours later? Sometimes I want to reboot my server and it should take place in the middle of the night when I'm asleep.

The keyboard seems to be dead, no keys work, not allowing me to enter the password.
Succeeded in connecting to internet using my wll phone. I can now connect using 'wvdial' command in root terminal. But I want to connect through terminal. I tried 'sudo wvdial' command. Then I am asked for my password. But I cannot type my password there. When I type, nothing appears on the terminal window. Ofcourse there's no problem with my keyboard.
View 5 Replies View RelatedFurther 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.
Why my pc freezes upon reboot once in a while, especially after certain updates? It never happened under Vista. I'm with Ubuntu 10.10 since October, never used Linux before. I think it's a bug in Maverick but I'm too lazy in reading the very long sticky! What happens at those very few times is a normal reboot, but a few seconds after a gradual and then complete freezing, you would have time to click the firefox icon but it will never open. Fastest way to get out of trouble is to reboot forced or other if you can.Maverick then works fine as ever.Just embarrassing I have to undergo all this. Can this bug be solved in the near future? My PC is Intel 32 bits 2 core with 2 GHz and 320 GB and I have 4GB RAM but I think it has nothing to do with the hardware, it has more to do with the OS!
View 4 Replies View RelatedI 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 ?
I have a Toshiba Laptop Satellite L355-S7905 Intel Celeron Processor 585 @ 2.16 Ghz, Mobile Intel GL40 Express Chipset. 4GB of Memory, 160 GB HD. Tri-boot: Windows 7, Unbutu 10.04 and Fedora 12.
Here is what happened: I had a hard/forced shutdown while using Ubuntu 10.04. Some warning text flashed on the screen before it went blank and I could not read it. Now when I turn on my laptop it freezes on the Toshiba set up screen. I can not go to the F2 setup, I can not go to the F12 boot seqence and I can not use F8 safe mode. Also the ESC button had no effect.
I have tried turning it on with the Win 7 cd in the drive but nothing. The same when I put my Ubuntu 10.04 cd in the drive, nothing. My guess is that the forced shutdown messed up the bootfile/grub order. The harddrive runs for a few seconds then stops. Should I attack the problem from a Windows view point or a Ubuntu view point?
I've installed xUbuntu on a machine I will be using as a file server. Everything is fine except one thing. If the server suffers an improper shutdown such as a loss of power the next time the machine boots it gets to the GRUB2 boot menu and then waits for a keyboard input.As this machine runs headless with nothing connected other than a network cable and power lead and is tucked away under the stairs it's quite an inconvienience to go to the machine and plug in a keyboard so I can press enter.Is there some way I could force the machine to boot as normal without stopping at the menu ?

I've just installed F15 KDE Edition, and as the title tells, I need to keep pressing F2 and/or Enter to make the system go through the boot up process, otherwise it freezes as long as i keep it without my interference !! and then it takes relatively long time to start the GUI, and when I switch to the console (using ALT + CTRL + F3 for example) and try to write the login or the password, there seem to be some 'bouncing' effect, that if I'm to write the login 'root', I get something like 'rrooott' ... however, this doesn't happen in the GUI .....
I have a multiboot system, with Windows7 and Linux Mint (based on ubuntu 10.4) installed along side. While Windows7 doesn't have any problem with my hardware, Linux mint has also some issues that cause the performance of media players to degrade (sound and video tearing) and cause repeated freezes to some applications (a game actually, 'wesnoth') until I press a key or move the mouse.
I have AMD Athlon 7750 dual core 2.7 GHz system, with 3GB DDR2 800 Ram, and embedded ATI Radeon HD 3200 with about 512 shared memory.
one more thing, when I booted off the live image to run the install program, I booted into the video failsafe mode (not sure of the exact name, but I think you got it, no mode setting) and passed the option 'noapic', so I suppose this options are still passed whenever I boot mysystem, as I get the text version of the progress bar during startup, rather then the graphical fedora logo ( i.e no mode setting) ..
Ok, this just started happening with ubuntu 9.10.
When it first happened, I didnt know what to do so i accessed all my data, backed it up in a diff partition, reformated my drives and reinstalled a clean 9.10. But now, every now and then (i think its when i use frostwire and have other programs running) my ubuntu keeps freezing up, it becomes non-responsive to anything i do, so i have to do a hard shutdown, after which, when i reboot, it is not able to mount /home, so i run FSCK and it fixes it, but ive done this about 3 times now, its starting to get a bit annoying, i dont know if anyone else has this problem, or if its a known bug. Here are my specs:
Running: Ubuntu Karmic 9.10 64 bit
3 Sata HDD: 1 TB, 750 GB, 350 GB
4GB Ram
2 Nvidia 7900GS
with a Pentium core 2 duo @ 3.0GHz

View 9 Replies View RelatedI installed office 2000 CD using wine, I did this on Ubuntu net-book remix on a NC10 using a networked CD drive. So the installation went okay, I then came to using the software, word opened and promoted me for my product key, which I entered correctly the window disappeared for a second then repaired, I entered the key again but then this caused the whole program to shut down, I have tried repairing it , reinstalling it all apart from uninstalling and reinstalling it. Which I have tried and subsequently failed
Right I got it to work, so for any looking for the solutions simply go to /home/(username)/.wine/system.reg and change the user name and the organisation either delete it or enter something, I entered my user name but I left the organisation blank but I left the quote marks that were there. Save it and the product code thingy should not appear again.
i'm using Ubuntu in my office. I have to report two issues with network connectivity.1. Wireless doesn't work if come back after suspend/hibernate the computer. The work around I follow is,a. Turnoff the wifi and restart the computer. (It won't shutdown. have to do force using the power button)b. Reinstall the network-manager_0.8-0ubuntu3_amd64.deb and network-manager-gnome_0.8-0ubuntu3_amd64.debc. Restart the computer (Again it won't shutdown. Need force.)d. Now wifi will detect the networks and shutdown works fine hereafter.2. Sometimes the wired gets disconnect frequently (thrice in 2minutes). Physical connectivity is good and working well in Windows.

I have recently upgraded to the 10.04 Alpha and have been unable to reboot or shutdown. I know it's just an alpha and therefore problems are bound to exist, so I tried reinstalling from a live cd of Alpha 3. But I am still unable to reboot or shutdown.To clarify what happens, I click on shutdown or reboot, the pop-up appears, I click on the shutdown/reboot button and it seems to complete it. It says that processes have been killed and something has exited with 255. But my computer is still on. I am guessing that Ubuntu is shutting down, it's just not actually shutting my computer down or restarting it.
View 5 Replies View RelatedI have a remote server (Xubuntu 10.04) which suffered an electricity brownout yesterday. The server itself is backed with an ups, but it is connected to a external firewire disk, which is not, and this disk malfunctioned as a result of the brownout.
The problem: Now, any process trying to access the external disk freezes and ends up in eternal D state in the process list, including ls and umount. Even trying to ls a directory which contains a symbolic link to a file in that drive just causes ls to freeze. These processes cannot be killed even with SIGKILL, so I proceeded to reboot but...
None of the reboot commands work. Instead they just get added to the ever increasing list of D state processes. I tried (sudo) shutdown -r now, reboot -f now and finally plain shutdown -h now. Is there anything else to try other than ask somebody to actually go to the server and pull the plug (which is not at all trivial)? Some way to tell kernel not to worry about messing stuff up, and just reboot?
