  • Running a startup program in terminal as sudo

    - by Brandon
    I need to run a python script in a terminal, myscript.py at startup (on Lubunt). This script requires root. I've setup a .desktop file that runs the following command: lxterminal --command="python /home/d/Jarvis/alarm.py && /bin/bash" The terminal window opens at startup and runs the script, but then closes when the Python script returns an error (because it's not being run as root). When I change the Exec= to this... lxterminal --command="sudo python /home/d/Jarvis/alarm.py && /bin/bash" ... (prefixing command with 'sudo') which works. However, the terminal opens on startup and displays the [sudo] password for d: \ prompt, requiring me to input my password. I would like the execution of the python script at startup to be completely automatic with no user interaction. How can I accomplish this?

  • Ubuntu install and boot failure 11.10

    - by Robert Moody
    I installed Ubuntu 11.10 on my machine alongside Vista, and upgraded to 12.4. I decided I liked 11.10 better, so I tried to install that again as my only OS, except I increased the size of the swap file partition to 2 gigs. It boots up fine off the CD, but when I install, it gives me a non-specific error, and returns me to the desktop. When attempting to boot off the hard drive, I get a black screen with a blinking underscore that starts in the corner, drops a couple spaces, and stays there. I managed to install 9.04, and am currently using that. The computer is a little outdated, but was fired up for the very first time last week, so the hard drive is in new condition and the CD rom drive is fine too. Running a 3GHzX2 processor. I ran a memory test, which came back fine, and being new to the linux environment, I've been scratching my head for the last couple days. How can I fix this?

  • The Ubuntu Advantage Service right for my non-profit?

    - by Robert
    My small 5 computer office currently runs on Ubuntu. 2 of the desktops run Windows7 in Sun Virtualbox software, and are used for Quickbooks. I am going off to college, and I am looking for a paid tech support solution to replace my IT position. I have an approx $300/mth budget, and I am wiling to discuss higher rates. Everyone in the office is currently comfortable with regular desktop usage, but I am handling all of the software installation and updates. I was hoping to get a total support package for all of their tech related questions, but I cannot find any services which will support linux. Is the Ubuntu Advantage Service something which can take my place? They would mostly need network help, printer help, and an occasional software compatibly troubleshooting session. If this is not a solution, does anyone know of a tech support forum/hotline which would cover all of this? Thank you for reading.

  • Know a little of a lot or a lot of a little? [closed]

    - by Jeff V
    Possible Duplicate: Is it better to specialize in a single field I like, or expand into other fields to broaden my horizons? My buddy and I who have been programming for 13 years or so were talking this morning and a question that came up was is it better to know a little of a lot (i.e. web, desktop, VB.Net, C#, jQuery, PHP, Java etc.) or is it better to know a lot of a little (meaning expert in something). The context of this question is what makes someone a senior programmer? Is it someone that has been around the block a few times and has been in many different situations or one that is locked in to a specific technology that is super knowledgeable in that one technology? I see pro's and con's of both scenarios.. Just wondering what others thought.

  • HTG Explains: Should You Shut Down, Sleep, or Hibernate Your Laptop?

    - by Chris Hoffman
    Computers can sleep, hibernate, or shut down. Sleep allows you to quickly resume using your laptop at the cost of some electricity. Hibernate is like shutting down your computer, but you can still resume working where you left off. There’s no right answer in all situations. Some people leave their computers running 24/7, while others shut down computers the moment they step away. Each of these options has its advantages and disadvantages.

  • 12.04 64 bit: Keybord not responding for about 20 seconds at startup/beginning of session

    - by Danilo
    I am running Ubuntu 12.04 64bit. When I get at the login screen and try to type the password for my user, I cannot type anything for about 20 seconds. After that, the keyboard starts responding and everything works fine. Mouse is responding normally as well as all buttons of the login interface (time/calendar, session selection (Unity/Unity 2D), etc.). What could be the reason for this behavior? How can I solve this temporary freeze of the keyboard so that I can type my password immediately without having to wait each time? Thanks for your time. EDIT: I tried auto login, but the problem is still there: the Desktop loads but even there, if I try to type something in the dash or anywhere else, I must wait about 20 seconds before I can actually start typing. Can the issue be related to some keyboard modules that get loaded little bit "too late"?

  • Netbook partitioning scheme suggestions

    - by David B
    I got a new Asus EEE PC 1015PEM with 2GB RAM and a 250GB HD. After playing with the netbook edition a little, I would like to install the desktop edition I'm used to. In addition to ubunto partition(s), I would like to have one separate partition for data (documents, music, etc.), so I could try other OSs in the future without losing the data. What partition scheme would you recommend? I usually like to let the installation do it by itself, but when I try to that I can only use the entire disk, so I don't get the desired data partition. I wish there was a way to see the recommended default partitioning scheme, then just tweak it a bit to fit your needs (instead of building one from scratch). So, how would you recommend I partition my HD? Please be specific since I never manually partitioned before. Thanks!

  • Load balancing on Ubuntu Server

    - by SabreWolfy
    I have Ubuntu 10.04.4 server (32-bit) installed on a headless quad-core machine with 2GB RAM. I'm running a command-line analysis which is analyzing a large amount of data, but which does not require a large amount of RAM. The tool does not provide any multi-threading, so the CPU load is sitting at 1.00 (or sometimes just a little over). I ran top and pressed 1 to see the load on each of the cores and noticed that "Cpu1" is always running at 100%. I thought that the load would be distributed between the cores, rather than loading one core all the time. I'm sure I've seen this load-balancing behaviour before in Ubuntu or Debian Desktop versions. Why would the Server edition work differently? The analysis will likely take several hours to run, so loading one core at 100% for many hours while the other 3 remain idle is surely not the best approach?

  • Help building pygtk application

    - by umpirsky
    This is my application. It is created with quickly. I would like to package it for Ubuntu now. I tried to package it with uickly, but that failed. At first, I was trying to install it using setup.py. But it is only copied in python lib dir, no icon, no desktop file installed. Then I tried to follow this guide, but I ended up with package without icon and it was of bad quality, but most important of all, it does not use setup.py, and it was pretty complicated. I would like to automate packaging process Can someone point me in the right direction, some examples of existing apps that have automated packaging etc? Thanks in advance.

  • Display launcher over a GNOME panel (instead of under)

    - by Greg Treleaven
    I've set up my desktop so that I have a classic style gnome-panel at the bottom to show my active applications with a main menu button on the side. The problem is that the panel stretches across the whole width of the screen and over the launcher, making it difficult to access the icons at the bottom. I could untick the expand option in the panel's properties, but there's no way to resize it so it takes up the rest of the right part of the screen, which is what I want. And if enough applications are open it stretches all the way anyway. I don't want to auto-hide it either. What I'd like to do is make the launcher go over the top of the panel so I can fully access both the launcher and the panel at the same time. If it's possible, how do I do this?

  • Bring the Windows 8 'Start Menu' back!

    - by ihaynes
    I've been using the the Windows 8 RTM from MSDN for a week but the more of my normal software I load onto the machine the more awkward it becomes using the new 'Metro' (yes I know that name is now not used) 'Start' screen. Yes, you can oraganise your programs in groups, or you can add them to the Quick Launch bar, or you can create alphabetic folders on the desktop but sorry Microsoft, none of these are as logical as the alphabetic Start menu of previous Windows versions.Fortunately the good people at Stardock have a solution in 'Start8', which brings the Start Menu we know and love back to Windows 8. It's still in Beta and the current one runs out in October. I'm looking forward to the final release and like lots of other users, I'll be happy to pay for this.Lets hope Microsoft either reinstate the Start Menu in the first service pack or gives us a usable alternative. In the meantime, here's an excellent solution.http://www.stardock.com/products/start8/

  • Install a Mirror without downloading all packages from official repository

    - by Sam
    I first gonna explain the situation: I have a Laptop which is connected to a wifi connection, and a Desktop which can not be connected to Internet (the modem is too far from it), and i want to install some software on the last one. (The two PCs are running Ubuntu 12.04, and are connected with an Ethernet cable) I've already searched for a solution, but all I've found was the use of some softwares that should have been already installed on the "Internet-less PC". ( Keryx, APTonCD ... ) What I want to do is to create a mirror in my laptop which contain the packages i have in this one ( situated in /var/cache/apt/archive ) and i don't want to download all the packages from the official repository, I actually don't need them. Can someone tell me if it is possible to do that ? Thanks,

  • Ubuntu 12.04 wired ethernet not working and wireless not working, How do I fix it?

    - by Eloy
    I am new to ubuntu. I recently installed the latest ubuntu for desktop from http://www.ubuntu.com/download. I was very excited to start using ubuntu until I booted the computer and saw that i couldn't connect to the internet at all. I have spent hours trying to figure this out. I keep running into people suggesting installing drivers etc. I have tried about everything and nothing seems to work. I have the ethernet cable connected to the computer but it doesn't recognize it. I ran the following: lspci | grep -i eth and I get this 09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5752 Gigabit Ethernet PCI Express (rev 02) Any help would be much appreciated. I am kind of bummed I have spent all this time tyring to get the internet to work and haven't even gotten to use the power of ubuntu Update copied from comment: Changing the Ethernet cable to a different one fixed the problem.

  • Split screen and other issues on Ubuntu 11.10 with ATI graphics card

    - by garus
    Ever since updating my Ubuntu 11.04 to 11.10 I experience issues with graphics. The biggest is the "split screen" effect where my desktop is shifted to the right, resulting in having Unity bar in the middle of the screen. As shown here: http://i.imgur.com/I8nmZ.jpg This changes from boot to boot, sometimes it's on the left, sometimes in the middle. What I tried: Removing fglrx drivers completely Installing post-update version of them, but installation is broken ATM in the Ubuntu, so no go. No one is even trying to fix it (bug report https://bugs.launchpad.net/ubuntu/+source/nvidia-common/+bug/873058 and a couple of duplicates out there) Also using the open source "radeon" driver results in the same (I have a better successful boot ratio with this one, proprietary rarely lets me boot) Other artifacts are: serious screen tearing weird lines flickering in random places lagginess Did anyone experience that? My specs: Ubuntu 11.10 AMD Radeon HD 6950 1GB

  • How should I trouble-shoot a frozen startup screen?

    - by Brian Dant
    The Problem: I'm running 10.04, and it suddenly started freezing after it boots. I can move the mouse, but I can't select anything. When the problem first started, there were only two things on the screen: 1. Gnome-Do 2. "Unlock Login Keyring" dialog box What I have done thus far: Asked myself if the keyboard was plugged in :-) Yes, it is. Tried to use ALT+F2 or CTRL+ALT+F1 per the "What Should I Do When Ubuntu Freezes" question. (Neither were responsive) Tried to reboot using the REISUB method (which did reboot, but I still had the same problem upon restart) Gnome-Do was in the autostart folder, and I removed it by deleting ~/.config/autostart/gnome-do.desktop Deleted my password keyring per this blog post Tried to kill and restart X with ALT+SysReq+K (Screen went black but X didn't restart) Tried to hit the Esc button What my screen is currently showing: My screen currently shows the "Choose password for new keyring" dialog box.

  • How much does it cost to develop an Android application?

    - by raychenon
    Following the same iPhone question. How much can a development team charge for an Android app like the official Twitter Inc ? In general how much amount of time is devoted to build the likes of Google Goggles , Google Skymap, Gmail with server side applications included :) Now if you're a solo developer and proud to show your app. How much time have you spent so far ? What was your background GUI desktop in Java, C#, web developer, started from zero programming experience ? Disclaimer : I've developed Android apps ( 10 000 downloads) on my free time and one commercial to be published. Just to know the amount of efforts needed to catch up :)

  • Keyboard freezes when xorg crashes

    - by gsedej
    Situation is like that. Many times has happened that Xorg freezes and with it also keyboard. Quite some times because of some Compiz effects or Flash (fullscreen switch). Keyboard becomes totaly unresponsive, while mouse still works (I can move cursor, but can't click since desktop freezes) and music still plays and I can connect trough ssh. This is the only way I know I can try to solve problem - either by killing browser&flash or lastly restarting xorg server. This problem appears on more than one Ubuntu computer. My home dekstop with proprietery nvidia driver, on my work where I use noveau driever (opensource driver for geforce) and sometimes (but rarely) also on laptop with ATI graphics (using r300g driver which is really good!). Can someone explains why mouse still works while I can't input from keyboard? (I can't switch to virtual console or do R-E-I-S-U-B command) I have USB keyboard and USB mouse.

  • Sharing samba-folder with root access

    - by Industrial
    Hi everyone, I have a staging server in my network running Ubuntu server 10.10, being my main development area. As I need to access the files in the Apache root from other computers in the network, I have setup samba with the following settings: [www] comment = Apache root www path = /var/www writable = yes force user = root force group = root On the host computer, running Ubuntu 10.10 desktop, I am trying to mount the drive with a bash file looking like below: #!/bin/bash sudo mount -t cifs //192.168.1.5/www /media/www/ -o username=myusername,password=mypassword,rw,iocharset=utf8,file_mode=0777,dir_mode=0777 What happens is that I get mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) thrown in my face whilst trying to execute the mount. I've done exactly the same, with exactly the same smb.conf & mount-bash file on another computer in my network, but this just wont work. What am I doing wrong? I am running out of ideas.

  • Can't get vnc to connect

    - by Thom
    I have a server and my laptop. I want to be able to start vnc server on the server and then connect from my laptop. Both are running ubuntu 11.10 64 bit desktop On my server, i installed x11vnc. I set it up with a password, no view only password. I ssh to the box and typed vncserver :42 Now on my laptop, I installed gtkvncviewer and ran it. It popped up a box. I entered the picard:42 (the name of the server in my /etc/hosts file) and the password. I tried with and without the user. It always disconnects immediately. Can anyone point out what I'm doing wrong? Is it because I'm not running a GUI session currently on picard? If so, how can I start the Xwindows session remotely to connect with vncserver?

  • How to prevent WLAN connection from dropping permanently?

    - by Chris
    I have a desktop with a Fritz USB WLAN N stick and tried Ubuntu 12.04. Installation went fine and WLAN is working. However, connection drops permanent. Reconnecting manually fixes it but after a few minutes it drops again. It's connected to a Vodafone 802 box with WLAN N fix set. It seems that it works when I switch off N mode. But I need to test. Can someone confirm this issue or is there another solution? I have another machine with 12.04 (HP 625 laptop) running where connection is stable.
