Ubuntu 10.04 up : xorg.conf - missing? generate one!

1. Re: /etc/X11/xorg.conf - missing?

   yes; xorg.conf in 10.04 is no longer the standard... you can generate one.. it will use it when it's there.
   
   
   here's how to do that;
   
   
   

   Code:

   Switch to a tty ( press ctrl+alt+f1 (f2,f3 etc)

   login with your username and password.
   
   stop gdm with
   

   Code:

   sudo service gdm stop

   then generate a xorg.conf with
   

   Code:

   sudo Xorg -configure

   this will create a xorg.conf.new in your home directory)
   move the auto-generated xorg.conf.new to /etc/X11/xorg.conf
   
   
   

   Code:

   sudo mv xorg.conf.new /etc/X11/xorg.conf

   Make changes you want to try
   

   Code:

   sudo nano /etc/X11/xorg.conf

   and start gdm again with
   
   

   Code:

   sudo service gdm start

   When your thread it solved: go to thread tools > Mark this thread as solved
   for SIS 771/671 use xcompmgr to have transparent terminals. just load it at startup.
   
   And then they asked: what's a pbkac error?

   Your welcome

selective backup using find, grep, cpio

I find this script helpful to make fast backup copy of my unix/linux system.
What made the script special (at least to me) is that it will run across on SCO Unix, SUN Solaris and LINUX os.

cd /
find . -depth -print | \
 grep -v "files/dirs to be skipped" | \
 cpio -ovBc > /dev/st0

cpio utility is quite versatile and easy to use. pls refer to cpio mans for features.

================================================

I have several PCs and notebooks and Android phones from which I do e-banking transactions.. such as paying bills, paying creditcard, buying things from ebay, transfer money to studying kids etc etc... Every transaction's receipt is important... to keep track of which is which money is involved... but they are on several devices! ( i dont want to use cloud's drive : not now as yet).


to find all non-pdf files and put them into a text file my-non-pdf :

# find /home -depth -print | grep -v ".pdf" > my-non-pdf
   


to find all     pdf files and put them into a text file mypdf :

# find /home -name "*.pdf" > mypdf


oohhhh sambung lain kali.... coz dinner is ready,  wife is waiting for me.. :)

You could do this through find command,

find /public_html -mindepth 1 -iname "*.pdf" -type f > output-file

Explanation:

/public_html     # Directory on which the find operation is going to takesplace.

-mindepth 1      # If mindepth is set to 1, it will search inside subdirectories also.

-iname "*.pdf"   # Name must end with .pdf.

-type f          # Only files.

A related problem:

Speeding up a Shell Script (find, grep and a for loop) Hi all, I'm having some trouble with a shell script that I have put together to search our web pages for links to PDFs. The first thing I did was: Code: ls -R | grep .pdf > /tmp/dave_pdfs.out Which generates a list of all of the PDFs on the server. For the sake of arguement, say it looks like this: file1.pdf file2.pdf file3.pdf file4.pdf I then put this info into an array in a shell script, and loop through the array, searching all .htm and .html files in the site for the value: Code: # The Array pdfs=("file1.pdf" "file2.pdf" "file3.pdf" "file4.pdf") # Just a counter that gets incremented for each iteration counter=1 # For every value in the array for value in ${pdfs[@]} do # Tell the user which file is being searched for, and how far along in the overall process we are. echo "Working on $value..." echo "($counter of ${#pdfs[*]})" # Add what is being searched for to the output file echo "$value is linked to from" >> /tmp/dave_locations.out # Find all .htm and .html files with the filename we are looking for in, and add it to the output file find . -name "*.htm*" -exec grep -l $value {} \; >> /tmp/dave_locations.out # Adding a space afterwards echo " " >> /tmp/dave_locations.out # Increment the counter. counter=`expr $counter + 1` done This does work. However, our site is huge (1491 PDFs, and a whole lot of .htm and .html pages). Each iteration through the loop takes around about 55 seconds. I've calculated that this shell script will take 6 days to complete. Does anyone please know of a better (and significantly faster) way of doing this? Any help would be greatly appreciated. I'm a bit of a unix newbie, and it took me hours just to get this far.

how to install etherape on Centos

Provides

• config(etherape) = 0.9.12-1.el6.rf
• etherape = 0.9.12-1.el6.rf
• etherape(x86-32) = 0.9.12-1.el6.rf

Download

Download etherape-0.9.12-1.el6.rf.i686.rpm for CentOS 6
from the Repoforge (RPMforge) repository.
------------------------------------------------------------

Using RepoForge

First download the appropriate rpmforge-release package for your distribution:

• EL 7: x86_64
• EL 6: i686, x86_64
• EL 5: i386, x86_64, ppc
• EL 4: i386, x86_64, ppc
• EL 3: i386, x86_64

Then you can use rpm or yum to install the downloaded package. The package installation will enable the RepoForge repo for subsequent use via yum.
More detailed instructions and recommendations are available on the CentOS wiki.
Hints:

• Use cat /etc/redhat-release to find which release of EL you are using
• Use uname -a to find your processor architecture
• Use rpm -ivh package-filename to install the rpmforge-release package (also works with URLs)
• You can use wget or curl to download the package using one of the above links if needed (for example on a server with no X Window)
• Then you can use yum to install the available packages from the RepoForge repo, e.g. yum install --enablerepo=rpmforge-extras`
• Afterward, you can disable accidental updates from the repo by setting enabled = 0 in the repo definition file in /etc/yum.repos.d/

How To Install VLC On CentOS 6/7

VLC media player (commonly known as VLC) is a portable, free and open-source, cross-platform media player and streaming media server written by the VideoLAN project. VLC media player supports many audio and video compression methods and file formats, including DVD-Video, video CD and streaming protocols. It is able to stream media over computer networks and to transcode multimedia files.

The default distribution of VLC includes a large number of free decoding and encoding libraries, avoiding the need for finding/calibrating proprietary plugins. Many of VLC’s codecs are provided by the libavcodec library from the FFmpeg project, but it uses mainly its own muxer and demuxers and its own protocols implementations. It also gained distinction as the first player to support playback of encrypted DVDs on Linux and OS X by using the libdvdcss DVD decryption library.

For EL7:

Install  EPEL   from   http://www.unixmen.com/install-epel-repository-centos-rhel-7/
rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm

For EL6:

rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
rpm -Uvh http://li.nux.ro/download/nux/dextop/el6/x86_64/nux-dextop-release-0-2.el6.nux.noarch.rpm

Now:

yum update
yum  install vlc

===============================================

I ve downloaded VLC on my CentOS 6. When I play a video by double clicking on finder, or using the vlc command in terminal, it shows a black screen. Sound works fine though. Do you have any idea what could cause this problem? 3 Answers

up vote 1   down vote	Actually I solved with options, not code. Tools --> preferences --> Video and uncheck Accelerated video output(Overlay). :D So simple;;

up vote 1 down vote	My VLC version is 2.0.5 just installed with CentOS6.4. My problem was no sound and or picture. To get sound I did as advised: Tools > Preferences > Video Uncheck Accelerated video output (Overlay). To get video: Tools > Preferences > Video Change video output to X11 video output (XCB).
