Ubuntu randomly switches off. I eventually found out that it happens when my system is over loading. If my memory goes up to 100% use or CPU, Ubuntu powers off. If there some software that I can download to prevent my system from using 100% of its power, so it doesn't power off?
View 1 RepliesI'm building up an old PC for a friend. The PCs hardware is quite old. I decided Xubuntu would be appropriate - works well! Currently the only issue I'm having with it is that it does not shut down correctly. The last message I receive is "System Halted!" which stays on screen while the rest of the system is unresponsive. Initially I thought this was an ACPI issue, I was told to add acpi=force and lapic to the boot options but unfortunately this has not fixed the error.I'm really stumped with this issue. By coincidence I have a similar motherboard (May even be the same mobo) in a different PC which had the same issue but insisted that ACPI needed to be forced because the BIOS was older than 2000 (1997).
Because I'm stumped, have some output from various commands I've ran.

I've just installed F15 graphical desktop on a brand new 64-bit box. When I use the Alt key in the User menu to display the shutdown options and click the "Power Off" option, the box shuts down, but then immediately restarts. Is that supposed to happen? How do I get the box to not restart after powering down? Kernel is 2.6.38.6-26.rc1.fc15.x86_64. The box also auto-restarts after root command shutdown -h now

View 3 Replies View RelatedI have been using ubuntu for 4 years now on my decent laptop with 2 Gb RAM, dual core centrino, etc etc. Yet, in all those years I have been using this superior OS, I still have to do hard shutdowns because some program runs wild. I have lately 2 scenarios where I have to interfere with the process:
1: amarok crashes and leaves the python script for the gnome shortcut keys running at 100% CPU. Or: thunderbird-bin keeps running after apparently clean close of Thunderbird. That's not really bothering me, I just kill both processes.
The bigger problem is scenario 2: 2: VLC starts eating all my RAM (for no reason), my SWAP starts filling and my computer becomes unusable for 10 minutes. Or: my matlab script is too big and eats up too much RAM -> same. Note: I have nothing against SWAP because at many other times it's very useful
These are stupid and annoying problems where there is an easy solution:
1) automatically kill the stupid process that runs at 100% CPU
2) automatically kill the stupid process that eats up all my RAM

View 3 Replies View RelatedI have a server that only runs durring the hours the house is asleep, to avoid bandwidth hogging. I know there are ways to prevent bandwidth hogging, but I figured I'd kill two birds with one stone. My other goal is also to reduce power and cooling costs. My two computers between them make a very nice space heater in the winter, in summer they make it sweltering in my room.I'm sure it would be trivial to get the sever to power itself off every morning, but is it possible to get it to power itself on at bedtime? If not, I do have Wake on Lan working, is there a windows program that would allow me to send a wake on lan signal every day and then shutdown windows

I have two problems related to color scheme. First, is there any way to prevent web browsers from using the system's default colors? I use a dark scheme, specifically Obsidian Coast in KDE and Industrial in GTK. This doesn't behave well on web pages in Firefox, Arora, and Konqueror. (Opera is fine.) Sometimes a site's stylesheet will specify a text field's text color to be black, but its background is not specified, so it defaults to black-on-dark-gray. I've also seen such a field's background color specified as white while the text color was not, so it ended up being light-gray-on-white. Is there any way to keep browsers from ruining web pages? Also, even if the stylesheet doesn't specify the colors, the dark text fields and buttons still stick out like a sore thumb on a warm or bright page.
My second problem is this: I have a saved session that brings up my applications every time I log in, but the GTK apps Pidgin and Evolution don't match the GTK color scheme until I quit and start them up again. Is there some way of fixing or working around this problem?
Does anyone know how to (permanently) get rid of this?
As you might have guessed, typing the root password and pressing OK has no effect.

View 1 Replies View RelatedSo I am basically just curious about this, but is there a way to prevent fork bombs from bringing the system to grinding halt in Ubuntu, without setting hard limits on the resources available to users? I read about fork bombs on Wikipedia, and being the masochist I am (and not having any unsaved work), I tried entering those 13 characters into terminal. Wow. I have never seen a computer freeze up so fast.What really peaked my curiosity is that the same fork bomb has almost no effect on the performance of Mac OSX (10.6). I know that one can limit the availability of resources to specific users. Is that essentially what Snow Leopard is doing?

View 1 Replies View RelatedI've recently had my file system irrecoverably corrupted after a hard lock-up. This has happened to me before, a couple weeks ago, and both times I've had to reinstall. I don't know what is causing the lock-ups (possibly the binary nvidia driver..), but I would like my file system to be intact or at least recoverable next time it happens.What is the "safest" way to mount things?
I'll be using ext3 with data=journal, but I've read that disk write caching combined with a kernel crash or power loss can still screw things up. Supposedly, mounting with barrier=1 helps some, but doesn't work with LVM? Would it be wise to turn off disk write caching completely? I understand there's a performance penalty, but if it helps keep the file system consistent in case of disaster.
I'm using Gnome and I'd like to still have the ability to reboot/shutdown from one particular account as well as root.

View 2 Replies View RelatedI installed Ubuntu to use ddrescue to clone my dying drive and keep the log.Now the question is:Does Ubuntu really try to repair a corrupt NTFS disk during boot?If so, how can I change this behaviour, including any disks attached to the system in future?I had a similar question for the live cd, I think it should be easier now, as we can configure the system.Btw am I the only one to think an 'auto repair' by default is no good without asking for permission? It's something I dislike on Windows. A corrupt structure is likely a hardware problem, and in this case a repair can terribly damage the file system.

I would like to ask if there is a way of preventing a file from being deleted, but still retaining the option of editing it.
