Simple question: what parameters can be used to shutdown a computer running Linux/OSX in 30 seconds? I've always run Windows, where I would go shutdown -s -t 30 but the parameters are different. I've looked it up here but it will only let you shut a computer down at a specific time (like 8:00) rather than in a specific amount of seconds.
View 4 RepliesI am having a problem with my Fedora11, I am not sure wether it is software or hardware but this looks serious. My computer is running very slow and freezes up every few seconds. Every time I reboot I would get a kernel failure pop-up.
This is what the message says:
Kernel failure message 1:
Kernel failure message 2:

I am new to bash scripting (not programming in general).
I am writing a bash script that will run a Python script I have written.
I want to be able to do the following:
Pass parameters to the bash script via the cronjob (so I can have two cron jobs) one to be run with parameter 'foobar', and the other 'foo'
switch based on the parameter passed to the bash script (by switching, I mean an if/else based on the paramter passed to the bash script).
I have this problem on my workstation. The computer would effectively freeze for 2-5 seconds for no apparent reason, then continue as normal. While frozen the mouse would still be movable, but only on one of screens in my multi-screen setup. What can be the likely cause.
System:
CPU: i7-920
Memory: 12G of Patriot DDR3, 6 modules
OS: SLED 11, Suse Linux Enterprise Desktop, using Gnome
Main board: Asus P6T
Video: two Nvidia 9500GT connected to three displays
I am using memory at recommended settings of 8-8-8-1333. It has an XMP profile. Th CPU is a bit overclocked to 3.3 GHz, but my cooling more than allows for it. I ran the computer with all overclocks off and lower memory speed but the issue was still there.
Linux bash inline command to execute a program and limit the resource.As I know, to limit the resource I can use ulimit command.But, the problem is when I set the CPU time limit 1 second, and then I want to execute another program with CPU limit 2s, the ulimit command return an error like this: bash: ulimit: CPU time: cannot modify limit: Operation not permitted and absolutely my program killed in 1 second.So, How can I make the second program running with the CPU time limit 2 seconds?

sudo shutdown -h <time> or sudo reboot from the terminal I get a rather annoying beep sound. What's even more annoying is if I use the shutdown command to specify a time I get a beep every 10 minutes or so.
I've tried disabling the terminal beep in the terminal profile, disabling the beep in System/Preferences/Sound, adding "blacklist pcspkr" to /etc/modprobe.d/blacklist, and running gconf-editor from the terminal and setting /desktop/gnome/peripherals/keyboard/bell_mode to 'off' rather than 'on'.
About two weeks ago I installed ubuntu 9.10 desktop with a dualboot to my windows 7, which was already on there. everything went fine, but I couldn't configure my wireless to work, so after a few days I gave it a rest and basically forgot about; I just stuck with windows. anyways, yesterday night I installed a program called solidworks on my system. I woke up this morning, turned on my computer, and this is what happened-
it turns on for about 5 seconds, but when it hits "grub loading", after about half a second it restarts. it's basically an infinite loop, until i throw in a cd or hit f8, but I don't know what to do with either of those options, so I'm kind of stuck.
I'm posting this in the ubuntu forums because I have NO idea what's wrong with it, and no idea of where to start. I've got both installation disks, but I don't know what to do when I put them in. I've got an intel pentium 4 processor, and like i said, i've got a dualboot with windows 7 and ubuntu 9.10.
Almost every day, for around 15-20 seconds, my computer becomes unresponsive, while the hard disk makes a strange periodic sound (period ~2 seconds, half of it the sound suggests very intense disk activity, the other half - normal disk activity), and the hard disk LED stays on (not flashing, just on). I ran manually all scripts in the /etc/cron.* folders. Only the mlocate script seemed to cause higher than normal disk activity (but still low enough to not cause problems). I still disabled it, but the problem persists.
View 5 Replies View RelatedI recently installed Ubuntu on my spare comp.
It freezes after about 10 seconds after logging in. I don't know why this happens.
It's a Dell Dimensions 4100. Installation went fine. I did everything, didn't skip any checks. It finished normally.
And now my hopes of another working computer have gone down the drains.
At boot time, my computer hangs for 15 seconds before continuing. This is the message that I receive:Starting the hotplug events dispatcher: udevderror binding udev control socket 1...(warning).Waiting 15 seconds and trying to continue anyway...(warning).

I have openSUSE 11.4 KDE 64 bit. openSUSE is really great, but I hate the freeze when I startup my computer. Desktop appears but I cannot do anything. This takes approximately 20 to 30 seconds and than my plasmoid-networkmanager shows network is up. As from this moment freeze is over.
I already tried to switch off ipv6 and put nomodeset in grub, though this is not helping. Does anyone have any idea what this is and how I can solve this?

I'm trying to figure out what this process is that pops up when I run PHP Code:
top -i
every few seconds
PHP Code:
jbd2/sda1-8
The best info I've found so far says it might be something to do with ext4 journaling, but I've never seen this before. I'm running 2.6.33-rc5 if that might have something to do with it. Further the process hasn't been popping up for the last 10 minutes or so, but previously it was occuring every 2 or 3 seconds repeatedly for a minute or so.
So i just finally installed Debian Jessie OS, replacing Ubuntu. But now it is running extremely slow. It's not internet connection. The internet speed is running fine (Videos load quickly), but it's like the system freezes every 30 seconds or so. A video can be fully loaded but still stops and starts constantly. Just browsing the internet, or non-internet things do the same also. I switched back to Ubuntu to see if it was different on there, but Ubuntu is running fine.

View 7 Replies View RelatedI am trying to install 11.2 but it keeps freezing. I press install and the Linux kernal loads and afterwards I get a black screen and after 30 seconds the DVD player stops running. I have also tried to the online network install and the exact same thing happens. I also tried a DVD I have of 11.1 which I know is good since I have successfully installed it on other machines and the result is also the same. My computer currently has a dual boot of XP and Kubuntu 9.10.
I am returning to Suse after experimenting with Kubuntu but thought I would leave the Kubuntu on the machine (prefer Suse but Kubuntu installed very easily on my computer). Could the Kubuntu be causing this problem or is the difficulty something else? I have also tried the safe install and the other options to no success.
I am using latest kde version in latest opensuse. I am working with distro one and a half year now (of course I was doing updates all this period) The last twenty dates if I have a quite heavy session I can not log off (or shutdown the computer) I even tried from konsole qdbus org.kde.ksmserver /KSMServer logout 0 0 0
even that did not work (well right now I can not launch any new apps from kde, but I still work with the already running).
Sometimes when I shutdown Ubuntu 10.10 and try to turn on the desktop PC it fails. I then have to disconnect tower from the power source and plug it in after waiting a few minutes. This problem first started in Ubuntu 9.10. I have a hunch that it happens because I am shutting down with applications open.
I was told that this is a batter issue on my motherboard, but I've replaced it and still have issues.
