I can't seem to edit and save config files in the root system (eg: /etc/dhcp/dhcpd.config); it just says "permission denied" or the save option is blocked in the text editor.
I'm pretty sure I'm a root user, but how do I make sure? If I am a root user, how do I fix this?
It is denied permission because of the general system of how linux handles permission
Anything in the $HOME folder belongs to the user, whereas anything under / belongs to root. Any file created in an user accessible folder belongs to that user

@AmithKK Users may already have seen this dialog when installing software, could you include a smaller picture that shows the Run dialog as well? Multiple images are cheap ;) Also, I suggest to move the "easier" instructions to the top and leave the advanced material regarding su on the bottom.
@AmithKK - I would think about $DISPLAY = :0.0 and editors that save preference files on this one. You might find this a good reference superuser.com/questions/29/…

Hey moderators look at this question: askubuntu.com/questions/121678/…. The user blueXrider is abusing his rep power. He voted down my question! Look at the question. It is straightforward and it complies with askubuntu rules. So what have I done!? blueXrider you think you are great? huh!!
I'm no mod, but I thought the question might have been a little sketchy. Not worth a down-vote from me, but getting a multi-buntu disk working with an expanded on disk repo is a lot easier than working backwards from some other thing that was broken out of the box for you.
On the rep thing, a downvote loses two points. If someone things it's great and gets you upvoted back to zero you have a net gain of 8 points. It's just how the system works.
@Ravi yeah, if you go down that route, you already have to remaster a livecd and include it in that multicd thing that doesn't work for your (would be great if you can add how you created the image)
Still not happy with the answers on askubuntu.com/q/92379/6969, or am I asking too much? A simple answer that explains why permission is denied and instructions to use gksu/kdesudo. Perhaps newer versions of Ubuntu have an "edit as root" GUI option I don't know of?
cat is not an editor unless you consider concatenatign two files as editing... sed is an editor, useful for quick tasks like sed -i /etc/apt/sources.list 's,http://archive\.ubuntu,http://nl.archive.ubuntu,'
I heard that Unity is now more faster and it is nice on visual. KDE is also best and it has very nice visual effects too. But which is more productive??
my opinion, they're both better for different things. just go with what suits you. kde vs gnome vs unity vs.... is a zero sum argument. nobody walks away right
I would guess that it grabs them from whatever service. Googlechat for instance it pulls their google picture. You can set it to something else in gmail last time I checked....and on the rest of it I defer to @jrg
@wisemonkey I keep cleaning vents regularly, and the fan is dust-free as far as i can see.. And its a brand new machine.. ( well, probably 8 months old.. but i still call it new)
I am considering buying a Dell XPS 15 laptop. The laptop has a Nvidia 420m card which should work with Linux but I keep reading that the Nvidia Optimus technology isn't supported on Linux. I am not really interested in switching from Nvidia to Intel to save power but need to know that the Nvidia ...
on my hp, i have to manually set the fans to blow all the time b/c for some reason the nvidia card doesn't fire a temperature sensor and the fans don't kick up until they're too far behind to matter, but i don't have the optimus difficulties. just a regular card
You could try switcheroo to disable/switch your ATI card, but prepared for lockups. Also, a recent kernel is recommended, opensource drivers are mandatory ("radeon")
About the ugly dash, that sounds like you've a hybrid intel/ati setup? In that case your intel card is active by default and unless there is a hybrid graphics solution (or BIOS option), you won;t be able to use the ATI card. This is at least true for nvidia hybrids
Does it suspend? I.e. does it power off? Or does it lock up on resume?
The answers are good, but not perfect. The accepted answer suggests to use the terminal. New users haven't heard of it and may be scary about using the terminal
at the moment, I'd grant Scott the bounty as it's an easy answer, but a screenshot may finish it
+a short explanation (possibly linking to other answers) why permission is denied
It must be good enough such that future questions can be closed as an exact duplicate of it
... I think the accepted answer just needs a "invoke" gksu from the dash and a para about permission denied ... do you want me to add this to that answer?
Yes sure, please include a screenshot as a picture says more than hunderd words. As per Jorges suggestion, sudoedit may be better than sudo <editor here>
Add a note about being careful when editing files as privileged user, backups and why permission is denied (editing system config) and the answer contains everything I was looking for.
I noticed some apps in 12.04 started warning you if you ran them as root. I think I goofed and ran a web browser from a root terminal and noticed that one
it a good answer... but @pbr's answer is ok because @Matthew Wilson asks "I'm pretty sure I'm a root user, but how do I make sure? " this question has multiple sub-questions =D
please ... somebody can take a look a this... It's not that important but now It's personal =D http://askubuntu.com/questions/111129/trying-to-make-zeroradiant-work-on-lubuntu-11-10

I added that it's in the beging of runing scons target=radiant,q3map2 config=release ... never added that before becouse I didnt see it so I did this scons target=radiant,q3map2 config=release > error.log to save all there an then I found it...
I'm guessing it's the order of the arguments...you've got a dangling library out there. The only time I've seen that on purpose is when half of it is supposed to be linked in dynamically and some of it statically. Not the case here. Just my 2 cents
