Running Ubuntu Server 9.10.I have a couple of programs that I would like to start at boot, they will both run forever. I have created a cron job with @reboot and that will start a program, but if I have multiple programs in there it waits for the first to finish before starting the next.
How would I make sure cron is running every time my server is turned on? I want to make cron jobs, but I need to know that it is running when the server boots. Also, I used a program at some point that was terminal based and it showed be what programs ran when the server booted up. It allowed me to check a box and select which programs I could run at boot. If someone could tell me this program,
I'm booting ubuntu from my android phone via USB and it works great, the thing is anything i install or do while using ubuntu isnt saved the next time i boot from the usb unless its saved in my phones storage. I want to be able to keep booting ubuntu the same way but keep the programs i install there for the next time instead ohttp://mac.bigresource.com/add/add.phpf starting from scratch everytime.
How can I start multiple X servers by logging into same user and using same desktop environment like KDE or GNOME. Is this possible by editing .xauthority, .xinitrc etc files?
I have a problem with 'Starting File Manager' completeley filling my taskbar on startup.There could be 100 of them for all I know, as the taskbar ends up dividing into tiny slices for each.How do I find out what is causing this? Is there a log file I can check or some way to repair ubuntu off the Live CD?Recently installed some updates. Last night tried reinstalling Nautilus and Gnome (did that with commands from Ctrl Alt F1 ) but that has not helped.I'm running Ubuntu 10.04 LTS (64bit)Dell Inspiron 530I'm no Ubuntu / Linux expert, but I can try to find any info / logs required
I would like to ask if someone knows a command or a script on how to rename a multiple file in the directory starting at the end of the filename or at the .extension( i would like to remove the last 11 character before the extension) for exampleBelow is the result of my command ls inside the directoryQuote:
I'm wondering if it's possible to write some sort of script so I can have an icon on the desktop which opens a combination of programs I use together frequently.Specifically, I would like to have an icon called "keyboard practice" which does the following:
1) Open QJackCtrl and "click" on Start; 2) Open the Hexter softsynth and make the Jack connections between it and my speakers; 3) Make the Jack MIDI connection between my MIDI keyboard and Hexter.
I have matlab installed on a network (I am not the administrator) and we usually start the program by typing "matlab", then choosing one of the version options from the menu i.e. typing "n". So because of this, trying to run matlab programs or commands directly like this... matlab -r ProgramName
...does not work. I just get the menu as usual and everything else is ignored. I assume the admin has overridden the matlab command with their own custom script. So my question is can I start a specific version of the program by specifying the folder that the version is in? I thought it might be something like /opt/matlab/version -r programname
this might look foolish, but I am a bit of a linux noob. Let me know if I should just ask my administrator but I thought there might be something easy I am missing.
I use skype ALOT, and when skype is open and I'm in a call, no other program that uses a mic will function properly.
An mmo I play on-line has built in voIP, and the voIP only functions properly when skype is closed. (it does not work at all otherwise)
Just as a reference, if I try to use kRecord while skype is open it will give me an error saying that the sound card is busy, or something to that effect.
how should I go about sharing the mic between multiple programs?
Well I have been interested in programming for a while, and just found out about Linux and Unix. I started out with Java, but now I know I bunch: Flash, C++, C and others. I was working on a mac so I made a few flash games then started to work on iPhone games. I was board one day and I found out about Unix and I thought that would be something else to try.So in an attempt to learn about Unix I have been reading different articles about it, and have heard of using different languages in one program. The article I was reading didn't give any examples, and it assumed the reader has programmed Unix before.
So how do you write programs in multiple languages, which languages would you use, and why would you want to do that?
I'm using bioinformatics programs i run from console on my system or on the server and some of them don't have a option for use multiple cores/cpus.There's a way to force it? some programs have to run for days and use a single core...
I have 11.1 on a computer. I updated it yesterday. Now K3B, VLC, and XDVDShrink are all broken. Possibly other programs broken as well. VLC refuses to uninstall via Yast. These are high-priority programs for this computer. Multiple people use this computer for multimedia and there is not much to entertain ourselves with in our very cold climate. In other words, it is mandatory that K3B, VLC and XDVDShrink return to operational status.
Should I just upgrade to 11.3, try to fix the broken 11.1? I prefer using KDE3, not KDE4, but I can sacrifice.
I am curious of how to make a GUI interface that uses multiple programs and commands. I have found wxwidgets as the most likely candidate for making my own interface.Is this the best programming language for a beginner?
Normally when a program is open an entry is placed on the taskbar in order to easily find it, which is useful when a lot of programs are open. In Ubuntu 10.04, when I moved a program to the other monitor (I'm using 2 monitors) the taskbar entry also moves to the taskbar on that monitor.
Now I switched over to Ultimate Edition, which is Ubuntu 10.04 with a lot of stuff added to it. When I drag a program to the other monitor, the entry in the taskbar disappears, but it does not reappear in the taskbar of the other monitor. So now the only way for me to find a program on this monitor if its hidden behind other windows is to use alt-tab.
A function by name abc is called in many files. I want to copy all the lines with the function call to an output file.A simple grep on function name doesn't help me as the function call is spanning across multiple lines as follows:
abc(parameter1, parameter2, parameter3);
So I want to copy all the three lines (till semicolon) to the output file.The problem is because there are more than 200 calls for the same function and I cannot do it manually
Can't seem to open certain things. For example Synaptic Package manger. It just shows "starting" etc and then nothing. Same thing with partition edd root terminal.Terminal runs fine (and i can su root from there) as do other things such as firefox,em monitor,update manager add/remove applications. apt-get still works fine. Just want to mention i have 500 megs of ram. Any ideas? Are there logs dumped somewhere for this kind of thing? Synaptic package manager still runs using dpkg from the terminal.
I installed OS11.4 on my old laptop, Compaq Armada E500., 512MB RAM, ATI Rage Mobility. During installation I chose "minimal server" and added some development packages, lxde and a little more. I chose to start in runlevel 3 which is full networking without X. Still, when computer is booted it tries to start Xorg which doesn't work because of some problem w driver. The start-up seems to stop there, it never loads completely - seems most things in runlevel 3 are not started (see below) I can manually login on laptop and fix it - but never permanently, same thing again after reboot.
I have checked /etc/inittab & yast - both states default runlevel is 3. I have checked services to be started both directly, browsing directory /etc/rc.d/rc3.d/, and with YaST, it is very clear X should not load during boot. But, as said, it does.. I don't really care about the driver problem right now, I can fix that later when I have more time. So how do I stop X from getting started automatically?
More info, if needed: The installation also stopped with message on tty1 "Starting YaST2" and tty8 showing errors with graphics driver (mach64). The system seemed to be installed though, so I simply rebooted (issuing "reboot" from tty2).
[Code]....
I'm not completely sure where it stops, network is configured but keyboard is wrong and mysql & everything after is not started, so somewhere between S02network and S06kbd. I'm going to use it as a server for testing purposes so no X is actually needed - however I do want to have X & lxde installed just in case, my Internet connection at home is terribly slow so I need most things I might need in the future installed today.
We are working on a project to create a display wall of 8 monitors arranged as 2 high by 4 wide. Each monitor is connected to a single machine and all machines are networked with a master machine with its own, seperate monitor.
Our goal is to get the 8 machines to share a single desktop, with the master machine acting as the server. We have looked at using Xinerama or NMM, but we are unsure about how to get started configuring the multi-machine, multi-head display.
My ubuntu 10.04 has two monitors connected both being treated as individual desktops.But only one desktop is showing the wifi network icon in the notification area.Is it possible to have more than one wifi icon going at one time?
I often use the rpl command to make changes to multiple html files at once. For example:
rpl -R '<br />' '<br /><br />' mydirectory However, I haven't been able to figure out how to change multiple lines. For example, let's say I want to change all occurrences of :
I'm trying to connect one computer to two others in an ad-hoc infrastructure.
[computer 1] ---- [computer 2] ---- [computer 3]
computer 2 is running Linux and has a single NIC wlan0. I want to it to connect to both computer 1 and computer 3 so each computer can talk to the other. No switch is available so it needs to be an ad-hoc setup.
So essentially, I have 3 monitors and i'm attempting to run 2 different window managers/sessions at once split up on the monitors. It is intended to be like this:
Code: [GNOME/Compiz - Screen0] - Left Monitor[code]......
I'm starting to have A LOT of opened windows in my machine. Sometimes within a project, I have e-mail/task management/personal e-mail/twitter, and a lot of different opened applications/terminals in my Linux workstation.Sometimes it would be interesting to have different workspaces to projects instead of this configuration I have nowadays that are classes of work (bad name, I know, but I think you got the idea).I'm starting to think about using two monitors: one with Corporate Management, Work and Personal. The second monitor is only the development state: each workspace here is about a project being worked on instead of groups of works like before. A workspace may be implementing different classes for example.
My question is: I just want to change to a second monitor using the mouse. I want to still be able to change workspaces in the same monitor using keyboard shortcuts. The keyboard shortcuts wouldn't change monitors, just worskpaces on the same monitor. All the tutorials I read (like this one) only tells how to use multiple monitors but doesn't answer my question about keyboard shortcuts.Does Linux (Ubuntu 10.04 Lucid Lynx or Debian 5.0.5 Lenny) support this envisioned setup (Different workspaces in a way that keyboard workspace switching only works in the current monitor) ? If so, how?I haven't tested this setup, that's why I'm asking. In this question the user says it works exactly how I want it to behave, can someone else confirm it?
I have an old pentium 3 computer that has ~7 NICs installed. These NICs are attached to modems and other networking equipment. According to the linux ping page on computerhope.com, it seems that one could send a ping from a certain specified NIC. How would one go about this?
