Disabling or preventing XFCE Sessions

Problem: XFCE keeps saving sessions. Even though I disable sessions XFCE still starts up with a session or even if I clear sessions XFCE still creates new ones.

System details:
Xubuntu 13.10
uname -a Linux Misaka 3.11.0-15-generic #25-Ubuntu SMP Thu Jan 30 17:22:01 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

I don't know what causes this and I'm sure smarter people have smarter solutions but this one worked for me: At first I thought it would solve its self so Got all my updates and I'm 'settled in' and I find out updates don't resolve the problem so here's how I did it: Delete everything in the .sessions folder then change the read/write permissions.

CLI:
cd ~
ls -al ~/.cache/ | grep sessions
cd ~/.cache/sessions/
rm *
cd ..
chmod 555 sessions/
ls -al ~/.cache/ | grep sessions



Warning, the "rm" command is both incredibly dangerous and a great way to fuck up your computer and it's probably irresponsible of me to even type it here; you may want to avoid using it. Not that I know this from experience, or anything...

Or do it with the GUI:

Perform the normal steps of session clearing:
Go to: Session and Startup
    XFCE Applications Menu->Settings Manager->Session and Startup
Click: "Session" tab
Click: "Clear Saved Sessions"

Close out of all that stuff and move on to the next part

Go to: Your Home Directory/Folder
    XFCE Applications Menu->Accessories->File Manager
    Click: the little house with your login name
Do: Show hidden files
    Click View
    Click "Show Hidden Files"
     or use the Ctrl+H keystroke.
Go to: .cache
Go to: sessions
Do:  Delete anything in there, you can leave thumbs, I did,
Go back to .cache
Right click: Sessions
Click Properties
Click Permissions
Do: change the access of Owner, Group, & Others to Read only

Close out of all that stuff and you're done

And so now, whatever it was that was causing sessions to be saved....can't....

Installing japanese Input

Oh, so...Yeah....Here is this. I made it a while ago but never linked it here. I suppose I should do that in the future.

This is me installing Japanese input support on ubuntu 9.04. The steps are pretty much the same for 10.04 and it seems to work for net-books as well.



Video is probably easier to follow if you pop it out, like it's hot; http://www.youtube.com/watch?v=BAA52SGzhL4


There is no sound because I always sound like a huge nerd over microphone

List apps. using an internet connection

Show apps that use internet connection at the moment

typing in lsof without any arguments is a terrible mess, however using some of the arguments in the link makes some pretty output

Go ahead and look at the manuals for lsof, ss, and netstat, then close them....They're all really long....Reading is for chumps.

What type of ram do I have?

Problem: I wanna look at RAM I may be able to buy but I don't know what memory type I already have and even though my computer is right next to me it is still to far for me to go to to open up and see what type of ram it takes.

System details:
Ubuntu 9.04
uname -a: Linux Moneque 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009 i686 GNU/Linux

Solution:
use lshw

tl;dr....sudo lshw


*nix Systems come with a bunch of ls things; lshw, lsusb, and lspci are a few that I know of. lshw will list everything your computer recognizes as part of it, though I donno if that's printers and the such as well. lsusb Will list the details of your usb bus bits. lspci Will list your pci devices, video cards and sound rcards, this includes pci-e.

to use lshw you can fire up a terminal and type

lshw

That will, at least on my system, probably cry about wanting to be super user.....

aggitan@Moneque:~$ lshw
WARNING: you should run this program as super-user.

       physical id: 0               

The information this displays is good enough for somethings, like if you want to know a bit about your processor and so on. However some details, like the memory type will be omitted.

To fix this we run it with sudo....

sudo lshw

and that should give us more details.....

aggitan@Moneque:~$ sudo lshw

Now, depending on your system you may get more information that can be displayed on your screen at any one time so you'll need/want to pipe the output to a file.

sudo lshw >> somefile

If the file doesn't exist it will be created and written to.

So as far as the memory problem goes we want the segment that starts with
*-memory, it will tell us: where the modules are, how big they are, and what type they are.

The important parts here are the descriptions, it looks like my system is rocking DDR2 and the modules I have are running at 800MHz. So I would want to look at getting more DDR2 RAM that operates at 800MHz
