Can I redirect the output of the speakers to my microphone? I don't want to turn on the speakers.
What I want to achieve is, say I'm doing a video chat and want the other person to listen to the sound. I'd like the sound from the speakers to be routed to the microphone. It'd be helpful while I'm using headphones.
I want to secure my Ubuntu PC from any threats (network/online to local/offline protection). What all can I do?
I'm using Intel i5-2430M processor which is a dual core processor, but the output of /proc/cpuinfo shows four cores. Why? Is is because of hyper-threading?
If yes, is there any way I can see the actual number of cores?
Also, how can I see the sizes of L1 and L2 caches?
Output of /proc/cpuinfo: http://pastebin.ubuntu.com/1206427/
When I try to use Screenleap it asks me to install Java. However, I have openjdk and icedtea already installed.
How can I make it work?
So, if there is some problem with my computer, be it hardware or software, what are the major log files and where are they located?
Also, is there a generic location where log files of the other packages might be located?
I want to know how linux kernel used in Ubuntu manages concurrent access to shared data?
I've been using Lubuntu Netbook for quite a few days (on Asus EeePC 1015PX), but recently I encountered a problem. I could not copy files to my root partition. I looked for the files that were eating up space, found some log files of huge size and deleted them.
It worked fine for few days, but now it again shows the root partition full.

I've heard that Lubuntu consumes less resources than Ubuntu. Is it because of the fact that Lubuntu uses different desktop environment and window manager?
If so, would it be equivalent to install lubuntu-desktop on top of Ubuntu rather than doing a fresh install?
