I have a mac book pro and I need to test ubuntu under virtual machine.
I have downloaded both xubuntu 13.10 64bit both ubuntu 12.04 64bit
I have downloaded Virtual box, created a new machine (with all default settings) and set the .iso file downloaded from the website (no dmg transformation, just plain .iso download) and.. ubuntu is crashing during the installation just after time zone setting and xubuntu crashes just before the installation..
I am on a Ubuntu 12.04 32bit. I have installed Cuda driver and toolkit, and now I want to remove them.
I have installed manually so they does not appear in synaptic/apt.
I have removed the driver from "Additional Driver". Well, they are inactive but still in the list. How to completely remove them?
Then, I have the toolkit in /usr/local/cuda, how to remove it completely and safely? I don't think that rm -r /usr/local/cuda is the right way..
some advice
I need a bash script for flattening a directory with same names, and get an ordered output after a conversion.
input folder structure:
/in1/file1.wav
/in1/file2.wav
/in1/file3.wav
/in2/file1.wav
/in2/file2.wav
/in2/file3.wav
/in2/file4.wav
/in3/file1.wav
/in3/file2.wav
and I need an output directory like this:
/out/file0001.mp3
/out/file0002.mp3
/out/file0003.mp3
/out/file0004.mp3
/out/file0005.mp3
/out/file0006.mp3
/out/file0007.mp3
/out/file0008.mp3
/out/file0009.mp3
where /out/file004.mp3 is the mp3 conversion of /in2/file1.wav
I've done some trials with find -exec but I can't get it to work
(don't worry about conversion, I just use ffmpeg -i fileinput fileoutput.mp3)
I'm not an experienced programmer but i'd like to become one, one day : )
I've seen a video in which a programmer is using a Vim session with 2 windows (and I know how to do, with :vsplit) and another horizontal window in which he has the terminal.
I don't know how to achieve this last horizontal window for the terminal. Can anyone here give me advice?
I'm working on a computationally heavy code that - for now - crashes a lot, but I'm still working on it :) When it crashes, I can't close the GUI window; I have to open a shell and kill -9 the process.
It is a Java process and it is easy to find:
nkint@zefiro:~$ ps aux | grep java
nkint 2705 16.6 1.0 460928 43680 ? Sl 12:23 0:08 /usr/lib/jvm/java-6-sun-1.6.0.26/bin/java -Djava.library.path=something something
nkint 2809 0.0 0.0 4012 776 pts/0 S+ 12:24 0:00 grep --color=auto java
nkint@zefiro:~$ kill -9 2705
Now it is easy but quite a mechanical task. So normally i wait for about 7-8 processes to crash, and then kill -9 each of them.
I want to do this in an automatic way. I think that it should be easy to pipe some commands to take the id of the (n-1) results of ps aux | grep java and kill it but I don't have any idea where to start.
Can anyone give me any hints?
I have a directory like this:

randomized_quad1080.png
randomized_quad1095.png
randomized_quad1110.png
randomized_quad1125.png
randomized_quad1140.png
and I want to rename the first files adding 0 in front of number, like:

But I don't know how. Some help?
I'm on Ubuntu 10.10, and I've just upgraded opencv to 2.4.2.
The problem is that each time I open a new shell and try to compile and run, it compiles but doesn't run due to the following error:
./a.out: error while loading shared libraries: libopencv_calib3d.so.2.4: cannot open shared object file: No such file or directory
As far as I can see, this file is located in /usr/local/lib/!
I can get it to run by running the following beforehand:
export LD_LIBRARY_PATH=/usr/local/lib
How can I fix this issue?
i've tried to download XAMPP, untar it in /opt/lampp and launch
sudo ./lamp start
but i get this output:
Starting XAMPP for Linux 1.7.7...
XAMPP: Another web server daemon is already running.
XAMPP: Starting MySQL...
XAMPP: Couldn't start MySQL!
XAMPP: XAMPP-ProFTPD is already running.
XAMPP for Linux started.
so i opened synaptic and i have installed mysql server.
now i have 2 problems, if i restart my ubuntu 10.10:
every time i restart my ubuntu i have to retype
sudo /etc/init.d/mysql stop
if after stop mysql daemon i relaunch lampp i get same message: XAMPP: Couldn't start MySQL!
/var/log/mysql.err and /var/log/mysql.log are empty..
I've read a lot of discussion about a new Ubuntu configuration tool: gconf is replaced by dconf.
Why is this change being made? Why is there so much debate about it? Is it too difficult to create a gconf2dconf migration tool?
I'm on Ubuntu 10.10, and I've just joined the Linux world coming from OS X.
I'm learning about runlevels and the rc directory in /etc/, and everywhere (manuals, tutorials, etc) I'm reading about inittab. But I can't find it in my Ubuntu installation. Why? Does Ubuntu follow the runlevel model? How are rc and levels loaded without inittab?
i'm on ubuntustudio and i want to format my hd and try kubuntu (install in my acer notebook, no partion, no double operating system problem, only istall it) i've downloaded iso file ( kubuntu-10.10-desktop-i386.iso ), insert usb pen drive, then: system > administration > startup disk creator erased usb pen content, and "make startup disk" finally, reboot computer with pen inside usb port
normal boot didn't start (as expected) but only black screen with this signal:
SYSLINUX 4.03 2010-10-22 EDD Copyright (c) 1994-2010, H. Peter Anvin et al
unknown keyword in configuration file
boot:
i've tried different usb pen stick and different iso files (ubuntu, kubuntu, netbook edition).. always same problem (sometimes only the first line without "unknow keyword in conf file" error)
some advice?? sorry for my bad english
