Use nbd, the Network Block Device, and then rate limit access to it using say trickle. sudo apt-get install nbd-client nbd-server trickle

Switch to X (the graphical interface that is frozen) usually by typing Alt+7 and then type Alt+SysRq+k . This will kill X and it will restart. This is kind of a "nasty" solution but without additional details and debugging is the best I can offer. -- or -- logged in on a virtual console (or remotely) type sudo service gdm restart

Sometimes it's just the X server that is frozen. Try to get a console by hitting CTRL-ALT-F1. If that won't do, try logging it your machine using SSH (install openssh-server package first). If you can't get a shell, reboot. Once you have a shell, check the system logs (/var/log/syslog, /var/log/messages, /var/log/Xorg.0.log and ~/.xsession-errors). Scroll ...

Your best bet is to back up your files and re-install. I'm not sure what's causing the problem, but the 3 separate boot loaders sounds definately wrong to me. I would also advise doing a full dual boot instead of a wubi install because: What is the performance? The performance is identical to a standard installation, except for hard-disk access ...

I had the same problem, and fixed it thus: If you go to the Ubuntu Software Centre and download the Pulse Audio Volume Control (or from a terminal type sudo apt-get install pavucontrol). Then just run it, and your microphone should show up there. If your microphone shows up but you're still not getting any sound, unlock the channels, and drop one of them ...

In 13.04, I found that /sys/class/backlight/toshiba breaks after suspend, but /sys/class/backlight/intel_backlight continues to function (echo $number > backlight after resume from suspend). Some great folks over at Arch have figured this one out. This does the trick: Source: ...

Hmmm... Strange, maybe you'd installed it two times, one through USC and other through a downloaded .deb package, if so it's needed to find the other AWN you installed and uninstall it. But probably, you didn't do that, so what to do? Try typing in the terminal: sudo apt-get install aptitude sudo aptitude purge avant-window-navigator sudo apt-get -f ...

Add this line to your /etc/modprobe.d/alsa-base.conf file: options snd-hda-intel model=dell-vostro enable=1 index=0

I know this might sound crazy, but go to the sound preferences, under input, and make sure the check mark for mute is unchecked, it is checked by default....

You might want to look into ~/.xsession-errors for relevant error messages.

Boot from Ubuntu install media. Select Try Ubuntu without installing. Open GParted (Partitioning tool). Create a partition for Ubuntu (size that fits your needs). Create a swap partition (size minimum matching RAM). On the desktop click Install Ubuntu. Choose Something else. Select the partition you created for Ubuntu before.

You could probably extend the timeout in your system. Open the gconf-editor using sudo gconf-editor and navigate to desktop -> gnome -> session. There you find a key idle_delay. You can change that value by double-clicking on it. Depending from how long you are typically inactive you change it. So if you usually don't have FTP activity for half an hour ...

Ok, I manage to solve it. I just installed the libido package and now the indicator-sound package installed with no errors. Maybe the system needed a reboot with the package uninstalled or something. If someone's having this problem, you can try: sudo apt-get remove libido-0.1-0 sudo apt-get remove indicator-sound Restart your computer (this is the part ...

Have a USB 1.1 hub? Or a slow SD card? They'll get you down to under 10mbps.

# echo 1 > /proc/sys/vm/drop_caches That'll slow you down :) It'll force you to read from disk, instead of taking advantage of the cached page. If you really wanted to get sophisticated you could do something like fake a read error every nth time using the scsi fault injection framework. http://scsifaultinjtst.sourceforge.net/

My ideas: Make sure you always keep at least one older and stable kernel version installed. That way, if a new kernel update causes the panic, you will still be able to restart your system with the old one. Write down as much information as you can regarding the error. Take a photo of the screen output with your mobile phone perhaps. Post these messages ...

Here is a good introductory video tutorial to Ubuntu. That youtube user has dozens of other tutorial videos as well. He's using an older version of Ubuntu, but most of the basics are the same, assuming you aren't using the newest version (11.04), which releases in a couple days (April 28, 2011). Version 11.04 uses the new Unity layout, which is pretty ...

There is a step-by-step troubleshooting guide on the wiki.

Try blacklisting the acer-wmi kernel module: sudo nano /etc/modprobe.d/blacklist.conf add blacklist acer_wmi as a new line at the bottom of this file. then reboot. edit: The acer-wmi kernel module enables you to control the following: the wireless LAN card radio inbuilt Bluetooth adapter inbuilt 3G card mail LED of your laptop brightness of the LCD ...

I would say not. It is quite normal for a Hard Disk to have some bad sectors, they can be caused by many reasons, and four is a small number. A Harddisk can have bad sectors when it comes right from the factory. Bad sectors are listed by the disk controller and are remapped, not used anymore. Modern Hard DIsks have spare sectors to replace the defective ...

Looks like the kernel is just spitting out weird errors, unless your computer has a real usb device that is plugged in internally (such as webcam) which is being ignored, I think it's safe to say that the errors are erroneous. Update: I found a computer which had the same issues, it was caused by a faulty usb port on the computer and it was confirmed to be ...

REISUB time!!! Just press ALT+Pet Sys and type slowly REISUB, one key at time. If it happens often you should probably investigate why is it happening. Ubuntu (and linux) is supposed to be rock-solid because it's usually rock-solid ;). This behaviour is anything but normal.

Have you tried just pressing Escape? Seems silly but I used to have something like this happen to me. Gnome would load up and a keyring unlock prompt would show. If I entered within a minute, fine. If I took too long the system would focus on something else (that I couldn't see) and the mouse or keyboard wouldn't let me move back to unlock it. One day I ...

Maybe you need to defragment your windows ntfs system. If the Ubuntu partition created by wubi as a file in windows' ntfs filesystem is very fragmented (it is a quite large file), then it would take a lot of movements by the disk head and hence slow down the boot time. Another issue to look for are timeouts that block other things. Networking used to be ...

If I recall an article I read once on lwn.net Once the computer is booted it keeps track of time by the clock frequency of the system as this is more accurate than the quartz in the cmos and saves an expensive and (relatively) slow BIOS call. There was a problem with virtual machines having their CPU time sliced that caused the problem. This person has a ...

While I'm not sure what is causing your system clock to drift so badly, you can install ntpd to keep your clock in hand - it continuously adjusts the system clock based on the calculated drift. sudo apt-get install ntp By default it syncs to ntp.ubuntu.com but you can edit /etc/ntp.conf if you want to change the NTP server. For more details see the NTP ...

Maybe your CMOS battery is getting empty (the battery on the motherboard itself). You can hit F1 (or DEL according to you motherboard) at the first seconds during pc starup to enter BIOS. in the BIOS you can check the hardware clock. Just let the computer run and check if the time stays correct (during this time you can't use your computer) If the ...
