I'm running Ubuntu 9.10 otherwise flawlessly on a 2007 core 2 duo Macbook. Right now its set up to triple boot with OS X Snowleopard, Windows 7 Ultimate, as the other operating systems. I'm asking because I'm frequently having to force my system to power down after shutting down from Ubuntu, and I'm concerned that I could be corrupting files and damaging my hardware.
View 1 RepliesLast night I shut down my computer and left, since it goes automatically after I tell it to shut down. This morning, my computer was still on, with some shutdown messages like "Stopping MySQL server mysqld" and such.
The last line said "deactivating swap..." and didn't appear to be doing anything. code...
i'm having a problem shutingdown my ubuntu 9.10. When I shutdown, it hangs after "Deactivating swap". It doesn't say fail or ok, just hangs there. Keyboard is still working.

So my Ubuntu 9.10 install has been hanging on boot lately. At first I thought it was a problem with the 2.6.31-20 kernel, because that is the default boot option in GRUB2. It seemed things worked fine if I instead chose the 2.6.31-19 kernel, but I had that hang yesterday too.I also had 2.6.31-20 boot just fine yesterday. Once. Next time I tried it - system hang.
What I mean by "hang" is,I would see the GRUB OS selection screen (I have 2 versions of Windows and 2 versions of Ubuntu on this machine),select the first choice (Ubuntu with the 2.6.31-20 kernel),see the "pulsating white Ubuntu logo" briefly,then a bunch of scrolling text, then...blank screen.Then nothing.I let it sit for a few minutes to a few hours when it did this, but nothing further happened.Then yesterday, I decided to let it sit the whole time I was at work, approximately 9 hours.I came home to a screen with the white Ubuntu logo and the following error message:
Code:
One or more of the mounts listed in /etc/fstab cannot yet be mounted:
swap: waiting for UUID=3fba81a3-de14-4f56-9e7b-ace95d933a0e
/proc/bus/usb: waiting for none[code]....
So it looks like I have a disk partition that refuses to mount sometimes.Gparted for some reason wouldn't tell me the UUIDs of swap partitions.They also don't show up in /dev/disk/by-uuid. Using the bootinfo script, I found out that 3fba81a3-de14-4f56-9e7b-ace95d933a0e is the 4 GB swap partition associated with my Ubuntu 9.10 install.The disk that partition is on is rated "healthy" by Disk Utility, with only a few bad sectors. The HDD is about 7 years old, so it's in remarkably good shape.What could cause this swap partition to not mount during boot, and how do I fix it?
Does one need to Check the Swap filesystem, from time to time
View 4 Replies View RelatedI have Ubuntu 10.04 installed on my PC with 1GB of RAM and 3GB of Swap partition. But the machine gets hung or reboots itself when the usage is even marginally higher. This is the output of "free -m" for Swap:
Swap: 2908 11 2897
I have tried increasing the swappiness to 80, and this not made any difference. I believe the RAM is taking up all the load and none of the pages are going in to the swap. Hence the slow response and the frequent hung system. I know this is an old PC but Windows XP (installed on another HDD) runs way better on the same configuration.
I'm running 11.04 on my Dell SXPS 1645. Today I unplugged my laptop from AC power a few times and after about 10 minutes, Ubuntu would hang, not responding to anything. Frozen mouse, frozen keys. The ONLY thing I could do to get it out was to do a hard hardware restart by holding down the power button.
It happened twice on Skype (and I thought it was just the buggy 2.2 beta that was hanging my beautiful OS), once while installing a printer, and once while I was just futzin around on firefox.
When the pc is powered up it takes ages for the login screen to come up and after that it hangs then comes up with a power manager is not responding fault, when I get into the desktop it takes ages for the top bar to appear and I noticed that the wireless usb dongle takes ages to connect. USB hang at boot? I have recently installed a usb printer. Weirdly a reboot fixes the issue, it seems to be at times the very first boot up where the problem arises.

View 4 Replies View RelatedI have a HP Pavillion DV7 laptop running Ubuntu 10.04, and I am having some problems with Ubuntu handling a network connection. Every so often, I leave my computer in locked mode overnight to download something. But, when I do this, the network just deactivates early on [there is a symbol of a blank wireless symbol with a red "?" by it]. Both the wireless and wired network connections are deactivated, and I am using a wired connection. This also sometimes happens in suspend mode, too, but less often. I have to restart my computer before it will connect again, as logging out and back in again does not suffice.

Everything is fine (so far) except that the only way I can get the internet to work is to plug in a hard line, then activate the driver (it downloads), then search for the wireless router. Here's the issue:I don't understand why I have to plug in a hard line to activate the driver. Shouldn't it stay activated once I download and activate it?

I'd really prefer not to go down the ndiswrapper route.
Firstly, I can see the PCI card and the driver it is using :

I have downloaded a Linux driver from Realtek but it will not compile. I have the latest kernel-devel, headers, and gcc. I can post compiler errors if anybody would like. They're all apparently to do with missing parameters.
I have an existing Ubunto 9.10 install sitting on a 500 GB SATA drive that was sitting in my second SATA port. I'm trying to swap the internal HD out to a new system that has a 500 GB SATA drive with Windows 7 on it as the primary drive, in SATA port 0. When I configure BIOS to boot from my Ubuntu drive, I just get a flashing cursor on the screen and no Grub bootloader like I was before.
Does this mean Grub isn't on my Ubuntu drive? Should I install grub on both my Ubuntu drive's MBR AND my primary Windows 7 drive's MBR, or only one of the other. The instructions I've been reading don't specify which drive to reinstall Grub on and which drive I should boot from, so I'm confused. How do I get it so that Grub acknowledges my Windows 7 install on the primary drive?
Can it be done? I finally got antiX running a 64MB base memory machine, bit I neglected to add a swap.

Could you either point me to a backup tutorial or give me the quick overview of preserving stuff with Ubuntu?
Currently and for the last half an hour System Monitor reports 31% in use by programs 68% in use by cache
So my 1GB of ram is maxed out. Things are kind of slow but not crawling (though at times, simple things like scrolling are stalled)
But it reports Swap: 0% in use.
Seems confirmed by the following:

I just installed the latest version of opensuse and I just put the RAM and SWAP widget on. I can see the ram meter is working fine but the swap space is always 0. How do I activate the swap so it starts using that space?
View 9 Replies View Relatedwhy the operating system is not using swap.I am using Fedora Core 13, it did have 4GB of ram, all of the ram was used. performance was poor. I used free and top to check if it was swapping - according to both, swap was NOT used at all. Never the less, I upgraded to 8GB and performance improved a lot.However, once again, free and top state that ALL the ram is utilised, yet NONE of the swap is utilised.

I am using Kubuntu Amd64 Lucid on my desktop and I have allocated 08.03 GB partition for swap. But today I have noticed that system monitor is showing this as 09.90GB which is incorrect.
I tried deactivating the swap from KDE Partition manager. Even after deactivating swap it still shows the swap as 1.9 GB. So there is clearly 1.9 GB swap added to my system. I am not sure how. Attached screen shot clearly shows the system monitor issue. One possibility is, I have 4 GB (3.7 asper system) RAM comprising two units of 2 GB cards. Is this 1.9 GB read from one of these? I tried to boot the system from Kubuntu AMD64 live CD and then it showed only 8 GB as expected. So not sure whats causing this issue in my installation.
I have got 2 disks available and would like to create 3 main partitions: one for file system (maverick), one for home folder and one for linux swap.
I read many howtos and now I feel more confused!
I would like to obtain the more efficient solution in order of speed (performance): as far as I can understand (not so far) .. it seems that the best choice is:
Quote:
disk 1: [beginning] ubuntu | home | others [end]
disk 2: [beginning] swap | others [end]
My situation now is, according to guides I read before:
Quote:
disk 1: [beginning] ubuntu | others [end]
disk 2: [beginning] home | others | swap [end]
now .. before moving all my staff ..
I thought to have understood that ubuntu use swap only for hibernation / suspend activities, and therefore it's recommendable to put the system at the beginning of one disk, and the home folder at the beginning of a second disk in order to have quickly two disk reading / writing on the right position without moving too much and spend time.
But now I'm confused because it seems that ubuntu DOES use swap for normal activity (and so it's better to put it) at the beginning of a second disk.
I always saw my swap next to zero during my activities .. is ubuntu using swap like windows with pagefile.sys?
I have Mythbuntu 10.04 installed on an exclusive HTPC and working great... until tonight. After letting the system update some packages (161 packages if I remember right), I suddenly have an issue where the graphical system won't start. After researching I found three error messages that might be causing that.
1. At the start of splash screen I see "UUID=xxxxxxxCD7 not ready yet or not present" I checked in /etc/fstab and found that this is the swap partition. I don't remember seeing this before so this could be the culprit.
2. I'm not at the computer in question right now but I saw a Plymouth error about "mountall" and then the message "plymouth command failed". Not sure if this could be the main error.
3. after a while (usually ca. 1-2 min) I receive thousands of errors of the kind "out of memory"... "kill process XXXX" (process vary wildly e.g. dbus-daemon, mysql, etc)... "process killed"..."respawning"
After error 3, I'm not able to switch to graphical console (ctrl-alt-F7). If I was in the graphical console at this moment, I simply can't switch to the CLI console. I'm always afraid of updating my system since I've seen lots of things breaking afterwards (usually the proprietary graphic drivers) but this is really strange.
As mentioned in the other two posts, my debian freezes when I use swap. Sometimes only the window-borders dissapear. However, this is not endurable for me. The answer "this is normal" is unfortunatly not getting censored. Even linux must be able to take heavy load without crashing.

I've got a problem with hibernating my laptop. It manages to copy everything to swap memory, but when it finishes, it won't power off my laptop. I have to manually turn it off (by pressing the power button for a few seconds). If I restart, everything is still there, so the hibernating itself works, but not the powering off part. My laptop is an Asus notebook K52F with Ubuntu 11.04 and Gnome 3.
View 9 Replies View RelatedI am in the process of installing Ubuntu 10.04 LTS on a Compaq Presario 5900Z desktop, circa 1999.
Because of a change to some IDE/SCSI drivers during 2008, no Linux distribution from the fall/autumn of 2008 onward will install on this system using their standard images, every distro I've tried to install this way would report I/O errors. There was a bug report filed on this at Launchpad some time ago. Running the images as Live CD's would work, but the actual install would always fail.
I began this by installing Ubuntu 7.10, then upgrading it to 8.04 LTS. The next step is to upgrade to 10.04 LTS.
When booting up, there is a console message that briefly appears that the BIOS (being from 1999) fails the cutoff (2000) and to enable ACPI, acpi=force must be added to the boot parameters.
The issue is when powering the system off, it will not power off by itself. At one time, there had been a different distro installed on this same system alongside Windows XP and both systems correctly powered the system off when shutting down. Ubuntu keeps the system powered on and I would have to hold in the power button for up to 10 seconds, until it powers off.
I do not know if simply adding acpi=force to the boot parameters will fix this, but I also do not know where to place this. The other distro used on this system actually came with a GUI interface that would allow for something to be added to the parameters. I cannot find anything similar in Ubuntu.
So, my questions are:
1. Will adding acpi=force properly turn the PC off at shutdown?
2. If so, where can this be permanently added to the boot parameters?
