I recently Installed Matlab and it keeps giving me this permission error, even after running the following command.
sudo chown -R ${USER}:${USER} ~/.matlab
Cannot write to preference file "matlab.prf" in "/home/"username"/.matlab/R2010a".
Check file permissions.
Cannot write to preference file "matlab.prf" in "/home/"username"/.matlab/R2010a".
Check file permissions.

I installed Ubuntu 9.10 and my sound does not work. Whenever I go to the Sound page and the Hardware tab to try switching from HDMI to Analog Stereo Duplex, whenever I select it and close the sound page, it never saves the switch. Whenever I open it again, the audio is right back to HDMI again. I don't see any "Apply Change" button or anything

Firefox "preferences" has an option which say, "keep my history for at least --- days".This does not make sense. If I enter 10 days, it will keep my history for 10 days or 1000 days. If I ener 100 days, it will keep my history for 100 days or 1000 days.ame thing!!Shouldn't it say, "keep my history for no longer than --- days"?I just set mine to 14 days and I still have a month of history.

I am very new to linux. I just got the dual boot working a couple of days ago. Now I downloaded MATLAB (2009b) from my university website. It came in a zip file...well I have no clue how to install it. I looked at the instruction manual, it doesn't really explain much.

I have a computer with Windows and I am running a Matlab program remotely in a Linux server. That (matlab) program will use an executable file (.exe) to analize some data; and that data will be used as input to a program that I can only run in the linux server.I need to run an executable file (.exe) from matlab in a linux enviroment. Is this possible?

I am trying to install matlab R2011a student edition in Fedora 15, 64 bits system. This version of matlab do not support 64 bits linux out of the box, but can be installed by adding -glnx86 as an argumenof the installing script.
However after running the installation script I receive the following error message:
Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/mathworks_32316/java/jre/glnx86/jre/lib/i386/xawt/libmawt.so: libXext.so.6: cannot open shared object file: No such file or directory
It seems to be a problem with libXext.so.6, however, I do have libXext library installed in my computer. The name of the package I have installed is:
X.Org X11 libXext runtime library
libXext-1.2.0-2.fc15 (x86_64)

I tried to mex two C files under matlab but faild. The system warned stdc++ cannot be found. I need the mexa64 files urgently. if someone can mex the C files using his/her machine. My server runs Debian GNU/Linux and the Matlab version is 64-bit R2010b. So the extension for the generated file would be mexa64. I'm using hotmail with the same user name as in here.

My employer issues pdf files with everyones work schedules. I copy the content and save it as plain text in a file called unformatted (hope to be able to automate this step someday). Im working on a SED script that reduces unformatted to only display what I want to see and saves the result in a file Iïve named formatted. After that I have to manually copy formatted and save it with that days date as a filename e.g. 2011-02-25 or whatever day is scheduled in the pdf, for use on a mobile device (Nokia N900). I noticed that the date occurs on certain lines in the file so I added a line like:
sed -n 's/^Date: (201[1-9])/([0-1][0-9])/([0-3][0-9]).*/1-2-3/p' < unformatted >theDate
That creates a file theDate with the date in it that I wish to use as the filename for this particular instance. So I would like to skip the file formatted all together and have the sed- script write to a new file using the content of the Date as a filename, but how do I make that happen? And of course it would be more elegant if I could skip the intermediate theDate file as well.

I am have problems with: gedit, abiword, mv, cp, touch, and rename.The text file was created with 'gedit' and save out of frustration with the title of 'Unsaved Document 1'.I now wish to give it a name and save it.'gedit' and 'abiword' will not save it with the name "Annie Street Arts Collective Play List 5/11", they will save it as 'Unsaved Document 1'. gedit' has work flawlessly for me up until this incident.I've never run into this before, I don't know what to start looking for. What do I look for to fix what is broken?

I have my final project and that is. 3 laptops connected to each other using switch and each of it is running ubuntu. One of the laptops is used as a web server. I installed already the xampp but my problem is I don't know how to save file in htdocs. In addition, I have no idea how my website in webserver can be viewed by 2 other laptops. It's just an intranet no need to be viewed through internet.

I was trying to install Ubuntu on a USB stick. So I went to the ubuntu site and downloaded Ubuntu. Now I have the .iso file on my computer but if I click on it, it asks me to burn but I want to save it on a USB stick. I did that with Universal USB-Installer. It goes smooth but when its finished its not the .iso file thats in it but just some documents and stuff. How do I get the .iso ? (I want to use it with VirtualBox but you need the .iso for that...)

My wife works in administration and is always writing letters. Finally got her to use openoffice but she was very upset no one was able to read her letters. Did I miss a step? As new, did I get her to use the wrong program for her work? I am trying to transition the family toward linux but composing letters may be a setback. How do we save files viewable for any PC?

When I try to save a file that I have edited using gedit I get a error Could not save the file /etc/pwrstatd.conf.You do not have the permissions necessary to save the file. Please check that you typed the location correctly and try again.Is this something to do with not being logged on as root? If so how do I log on as Root or edit the file as a root user?

I mounted a remote directory using sshfs and I can't save files using gedit, while saving same file using vi works. Changin permission to o-r (640) allows gedit to save files OK. Is there a way to change sshfs connection to make gedit work without chmodding every file? (I use -o uid=`id -u` -o gid=`id -g`, so that remote files seem to be owned by me)
Code:
$ touch test.txt
[!] test.txt appears
$ vi test.txt
[!] :wq -> saves just FINE

I sometimes stick my neck out and provide somewhat detailed, and often risky, "Mr-fix-it" remedies for boot problems. Now, I know it's possible to amend each command with "whatever_command > whatever.txt" in which case it'll place the command output in a file in /home.
But if you're directing someone to run a lot of commands as I did here is it possible to save the output of all commands to a .txt file without amending each command?
Or is it already saved somewhere that I'm not yet aware of? I wouldn't be surprised if the latter were true, I just haven't yet found it

Is there a file manager that I can use for Ubuntu which has a "session restore" feature. Think of a sort of "save all these tabs" feature except applied to the file manager only.And for additional clarification: I run several desktops and each one has a file manager on it with several tabs of the file manager open. Each set of tabs are related to a topic I am working on.

I have one Ubuntu 10.04 machine that is configured this way.I want GDM to prompt the user to enter their username via a text field, and then a password, instead of displaying a list of users to choose from.One way to configure GDM's appearance is to run the following from a terminal: gksudo -u gdm dbus-launch gnome-appearance-properties.If I remember correctly, there is a different dialog to run than "gnome-appearance- properties" that allows changing whether GDM prompts for a username or displays a list. But I do not know what it is.

While browsing following page [url] I get a random window popped up on my box the link which pops up is of following page[url]
In case any one wants to see what I am trying to tell just open that page [url] and try to click on some menu button in navigation bar. You will see an advertisement "Play online games"
Now I would like to tell Firefox-->Edit-->Preferences-->Content-->Block Pop up windows there is a tick on that box.
Also as I open that page[url] I do see a message in firefox which says this page tried to open pop up windows which have been blocked. And inspite of this message I get to see that advertisement of "playing online games" It has been so frustrating and annoying to each time close that pop up.
My question is inspite of the option of blocking pop up windows enabled why do I get to see this advertisement. Can I some how stop this behavior. I use Lucid 64 bit and Firefox 3.6.10
