I have a 7-hour wav file (recording of rain sounds), and I'd like to burn a CD from it.
How can I burn as much as it as will fit onto a standard audio cd so that it will play continuously for the 50mins or so that a CD usually plays for on my ancient CD player?
I'd prefer to be able to do this from the command line.
Normally I have caps lock to be a control key.
setxkbmap -option ctrl:nocaps
makes that happen, but I can't remember where I got it from or find any docs (man setxkbmap is singularly unhelpful )
Can anyone tell me the command to put it back to how it normally is, or at least point me at the docs that tell me what -option ctrl:nocaps actually does?
the xxdiff package seems to have gone missing in Raring Ringtail. Does anyone know what the problemis / how to get it back?
Sometimes my netbook (Dell Mini 10v with Broadcom bcm4322 wireless adapter, Ubuntu 12.04.2 LTS) gets into a state where it can see wireless connections but not connect to them.
Rebooting always fixes this, but is a pain in the neck.
Sometimes
sudo service network-manager restart
works too, but not always.
I suspect a problem somewhere in the network stack, probably driver-related, but I've no idea how to find out what it is, and the fault is too intermittent for blind debugging anyway.
Is there any way to force a reset of the entire network stack without having to do a full reboot?
Several different commands is fine. I can script.
Failing that, is there a detailed guide to working out what the problem actually is?
I've just installed 12.04.1 from scratch on my Mini 10v, and the touchpad is behaving a bit oddly.
It's got buttons integrated into the touchpad, and it looks as though a touch on a button is also being registered as a touch on the touchpad, causing all sorts of problems with clicking and dragging.
Is there a fix for this? I seem to remember on very old versions of ubuntu having to disable the lower part of the touchpad, but I don't think it's been an issue for some time.
I installed Ubuntu 12.04, and loathe the new interface so much I've switched to Xubuntu with sudo apt-get install xubuntu-desktop.
Very happy with that so far. But the typing break I always used to have set is part of gnome.
Is there an equivalent typing break app in xubuntu?
I need to configure my router remotely, and links etc won't work because the router config page uses javascript and refuses to run without it.
Obviously, shame on netgear for being this crap, but is there a text mode browser that will allow their abortion to run?
I'm sitting in a pub which promises wifi but in fact only seems to allow http and https over their standard ports, so no github, and no connecting to my home machine over ssh.
How can I bypass all this sort of stupidity for good?
I have a machine at home which I can leave running all the time. Both my laptop and my home machine are ubuntu boxes.
I'm thinking, http server on home machine, program on laptop catching all attempts to contact the network, encrypting them, and forwarding over http to the home machine, which then goes and does its thing over its clear internet connection, and sends the results back.
Then wherever I can get http over port 80 to home, I have proper access.
Is there an easy way to do it? Does that easy way have a simple page of documentation in the form of 'this is what you type on your laptop', 'this is what you type on your home machine'.
If not, what's the least hard way, and where are the clues?
So I'm trying to find all the mercurial repositories in my home directory
$ find ~ -name ".hg" -or -name ".git"
This works fine, but it finds a lot in the ~/.local/share/Trash subdirectory
How do I make it ignore these? Obviously there's grep -v, but it would be better not to search Trash at all.
Once upon a time, when I went to the battery icon on my netbook, I could get it to show me interesting graphs of the battery state, and how it had changed over time.
Nowadays, in this time of decay, all it will give me is a tooltip telling me how long I've got left, or how long to recharge.
Does anyone else remember the golden age of which I speak, or have any advice on how it might be regained?
my dell mini 10v running Ubuntu 10.10 runs ok for hours, but then will suddenly slow down drastically. Switching to a console shows lots of error messages, which also get into /var/log/syslog. These errors happen every couple of seconds. I'm figuring that the disk is failing, but is there anyway to be sure, and can laptop disks be replaced easily?

I've got /dev/sdb1 encrypted and mounted as /home.
The following line is in /etc/fstab:
/dev/sdb1 /home ext3 noauto,loop=/dev/loop6,encryption=AES128
and
#mount /home
works fine, but
#losetup -e encryption=AES128 /dev/loop0 /dev/sdb1
which I'm sure always used to work, gives:
ioctl: LOOP_SET_STATUS: No such file or directory, requested cipher or key length (128 bits) not supported by kernel
Does anyone know why? If the mechanism for aes encryption over loopback devices has been changed, how am I supposed to fsck such a drive?
