The Intro
I'm using my computer as a VDR/DVR using, shockingly -- VDR. But in order to record video reliably, you need to be able to write it at a good clip (5-10 MB/s preferably). I've been writing...

ah ha.. It turns out that the reason it had too many open files was on account of kpackagekitsmarticon.
I ran

sudo mv /usr/lib/kde4/libexec/kpackagekitsmarticon ...

+1 on htop. But your system monitor (or whatever the equivalent for Gnome might be) should also be able to sort by CPU. Whichever is the highest on the list is probably the issue. You can usually...

Hello everyone!
I'm having an issue with dbus-daemon using 100% cpu and I'd like to know if there's a way that I can generate good bug reports without needing to start graphical programs via...

Like he said, that's completely the point of having SSH.

But if you're worried about it, you can use SSH keys instead. They're pretty easy to make and somewhat tough to use if you're not used to...

I setup a Multiterminal/multiseat X, using one of the Community Documentation pages as a general roadmap. I was shocked to find that it actually worked, but there were some problems, most of which I...

I'm not thinking this directly relates to Ubuntu so I posted this in the Café..
It's a question about wiring cat5e/twisted pair and setting up a network in an extremely
confined space.

My house...

Oops! Sorry guys! I put the wrong specs up... (Goes to show I haven't actually seen the thing)

It has 16 cores on 4 processors, not 8 cores on 2 processors... Here's the /proc/cpuinfo:

Ha! I couldn't imagine trying to snowboard with a server - but it sounds like a good excuse to take a vacation to Europe!
It's not a rack mounted server unfortunately - actually, it's in a makeshift...

Actually the virtualization sounds cool - I think I might try that!
The games probably wouldn't work though - the server is in another state, so the internet link wouldn't be able to handle the...

A friend of mine just built a high performance server:
Dual- Quad-core Opteron CPU (/proc/cpuinfo available if necessary)
16 GB RAM (don't know what speed)
No special HD, just 120 GB (probably...

Looks like it's a QT3 program then.

Here's the code for qt3 (instead of qt4)


sudo apt-get install libqt3-headers

Sorry, I don't have much beyond that. That's always fixed it for me. "-p" helps if you're looking for options though.

It happens to me all the time, but I know the reason. I got a real cheap-o video card and it doesn't play videos or anything really well. Usually you can improve the jitter by sizing down the video,...

This is rather general but there could be several reasons for it. If you have read/written/deleted about 50k to 100k files, you might have worn out the disk. Otherwise, I would do a file system...

Also, as a general rule, you may want to try this


sudo apt-get build-dep SOME_PROGRAM

Where SOME_PROGRAM is the most similar program already available (maybe even another version of the same...

Chances are, this is what you need to build:

sudo apt-get install libqt4-dev

It's a perl regular expression (I think - I'm no perl programmer)

Most probably this is the syntax:

s/WHAT_TO_REPLACE/REPLACEMENT/g

BTW: I don't know if this is the case in perl, but you can...

Nevermind. I ran grub-install on the primary drive, adjusted the boot order, and now I can repair XFS without messing with GRUB (since now GRUB is elsewhere).
[SOLVED]

GRUB installed over my XFS drive (which had the whole disk).
It booted fine, and then I ran xfs_check, which segfaulted.
I'm not sure if it killed GRUB. How would I check (do I have to restart?)...

I'm afraid I don't know how to switch to the bcm43xx module..
I added bcm43xx to /etc/modules,
removed "blacklist bcm43xx" from /etc/modprobe.d/blacklist
added blacklists for b43, b43legacy and...

I'm not exactly sure what is wrong, but it looks like the wrong wep key was typed in.
Try looking at this:
sudo iwlist key
Don't post the output, but you should see your network key in there. If...

My laptop is regularly getting good signal strength (~70% most of the time) but gets terrible (~25% typical, ~75% occasionally) packet loss.
I thought interference would be a problem, as I am...

After df, try these two commands.. They may give a hint to the missing space:

sudo du -hs /var/log

du -h ~/.xsession-errors

I'm not an expert in corrupted files, but I imagine one of these would work:

dd if=/path/to/source of=/path/to/dest
or

rsync /path/to/source /path/to/dest
