  • Bash script not working as required with xbindkeys

    - by RanRag
    I made a simple bash script to display a notification whenever my capslock key is pressed. It works fine when I call it like bash capsnotify.sh. The problem now is when I bind my above script to capslock key using xbindkeys tool it doesn't work as required. It shows a notification caps ON when my caps is on but it doesn't show caps OFF notification when my caps is off instead it again shows the caps ON notification. capsnotify.sh #!/bin/bash value=$(xset -q | awk '/Caps/ {print $4}') if [ "$value" == "on" ] then notify-send "caps ON" elif [ "$value" == "off" ] then notify-send "caps OFF" fi .xbindkeysrc "bash /home/ranveer/capsnotify.sh" m:0x2 + c:66 So, the problem is after binding my caps lock key on both events(on/off) it shows caps ON notification.

  • Extended validation certificate not changing browser bar green in Firefox

    - by Max
    I'm having some problems with an Extended validation certificate on a site that isn't showing the green bar correctly in Firefox. Chrome and IE are working fine. When I load the page the bar appears for a few seconds and then disappears when the page has fully loaded. Someone mentioned it could be because of loading images over HTTPS, but I'm not sure how valid this case is. We have one image on the page that is loaded from another source over HTTPS, the rest of the images are stored in the file system on the server. FYI - its Windows Server 2008 and ASP.net UPDATE: Solved this problem - the style sheet was loading in a Google Font url using http, not https - changed it and now it's working.

  • Apache cannot find mysql database modules

    - by user809857
    I've created a simple django project and setup a mysql database. My simple project just creates an entry on the database. The project works fine when I use the built in development server provided by django (runserver) and it works well. But when I deployed the project on Apache and mod_Wsgi (Ubuntu server), django could not find 'books', which is in this case my table in the database. The mysql database that I use in runserver and apache are just the same. I also did rebuild the database using sqlall,validate and syncdb of django but still i get the error. What could be wrong with what I'm doing? Thanks

  • Kernel Panic: Not booting after upgrade from 10.04 to 12.04

    - by Jitesh
    I upgraded from 10.04 to 12.04LTS. Upgrade went fine, even restarted couple of times. Then the next day while booting into Ubuntu, after the grub, it gave the error Kernel panic : not syncing vfs unable to mount root fs on unknown block (0,0). I then booted into live CD and tried the following commands, based on other posts on this forum: sudo fdisk -l As the 8 was on /dev/sda1, sudo mount /dev/sda1 /mnt sudo mount --bind /dev /mnt/dev Now I got the message: mount: mount point /mnt/dev does not exist Then tried sudo mount --bind /proc /mnt/proc Again got the message: mount point point /mnt/proc does not exist. then tried sudo chroot /mnt Got message: chroot: failed to run comman '/bin/bash': No such file or directory Now have no clue what to do next. Unable to boot into Ubuntu. Please help. Jitesh

  • C or assembly code to find current cpu core speed

    - by honestann
    How can my application efficiently determine the following information peroidically while it executes: 1: current speed of each of the 8 CPU cores. 2: which core the code is currently executing on. My application is C and assembly-language, so any solution in either C or assembly-language is fine. This code needs to execute quickly, so creating, reading and processing a file generated by "cat /proc/cpuinfo" is much too slow. The cores slow-down and speed-up automatically, probably to keep CPU temperature under control. Therefore, a one-time measure is not sufficient for my purposes. My application already reads and subtracts the cpu cycle counter in assembly language to determine number of clock cycles, but my program cannot compute elapsed time in nanoseconds unless it knows the current clock frequency of the cpu cores (and which core the code is executing on). Thanks!

  • Hot to get XChat to trust CA certificate?

    - by Silvio
    I have created an SSL certificate authority including a sub-authority to issue certificates. I have copied the root certificate to /usr/share/ca-certificates/extra and added it to /etc/ca-certificates, then ran dpkg-reconfigure ca-certificates and update-ca-certificates. After it said "Adding debian:.pem done." I am now fairly convinced that Ubuntu knows about my CA. Now I issued a certificate for the ZNC irc bouncer from the subca, installed it onto znc, but XChat will not trust the certificate despite all the above. I also issued a certificate to use with apache2 and that one works fine after adding the root ca to chromium. Does someone know how I can get XChat to trust the certificate?

  • Multithreded UI desktop application issues

    - by igor
    I am involved into development a rich UI project: desktop windows application. Application uses asynchronous invocations and in its turn it should be ready to process external messages (events). The problem is clear: at first time it was built as a simple prototype and it was not stress tested and all was fine. Then application was grown: the number of calls to server and number of events from server are high and performance is low. What is more users noticed that sometimes performance is extremal low. Asynchronous invocations based on thread pool (BeginInvoke, EndInvoke), external events are going from WCF service (.NET 3.5). My goal is synchronization of all tasks and putting priorities to every executions in desktop application. My question is: is there any practice how to reach my goal: patterns, task priority list, others? What should I do at first, second and next times? Thanks

  • Unable to complete ubuntu installation

    - by Hugh Levinson
    I am not a computer expert and have no programming experience. I have downloaded Ubuntu 12.04 from the website using the Windows installer onto an admittedly old Toshiba Satellite Pro laptop. The download seemed to be fine. When I try to startup the laptop and select Ubuntu I get a long series of messages starting: "error: couldn't read file [0.7392640 Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0)" I have seen other entries on this messageboard with similar questions but to be honest, I can't follow the answers, which presume more knowledge than I have. I would be extremely grateful if anyone could suggest a solution.

  • Font rendering in Firefox is blurry

    - by Mehrdad
    A picture is worth a thousand words... so does anyone know how to fix this font blurriness in Firefox? (You'll need to right-click the picture below go to View Image to view it full-size; it's too small to see anything here.) Note: My other applications (and the Firefox non-client area, as you can see in the screen) are completely fine, so obviously going to System-Appearance and changing the font settings isn't fixing the situation. Edit: Not letting web pages to use their own fonts also doesn't help: See how the upper one is still sharper? Also, Firefox's own menu bar doesn't render the same way as the page content (menu bar below, page content above). They're both Segoe UI:

  • How to report a crash bug with nothing on screen

    - by winniemiel05
    I would like to report an installation bug, but I can't launch ubuntu-bug : On my tablet (LDLC Janus, an Intel based tablet without OS installed by default), I have a problem when I install Ubuntu 11.04 or 11.10. Once the installation is finished, when I reboot, there is ABSOLUTELY nothing on screen, but Ubuntu boot correctly anyway : I choosed auto-login mode and I can hear the login sound. Even if I Ctrl+Alt+F1 or F2... there is nothing. But the livecd works fine (even touch screen even if without multi touch). I tried to install 10.10 it works, but as soon as I upgrade the same problem occure. i installed Fedora 15 and then Fedora 16 (because of other problems) and no problems with them. I would like to report this bug on launchpad but I don't know how to do to give devs logs files and other useful files which could help debug. Thanks a lot for your answer, I would really prefer using my tablet with Ubuntu (I miss U1, USC, Unity)

    After some installing, tweaking, ... the IBus icon is missing at startup, although it's working fine: $ ps -ef | grep [i]bus quanta 1918 1890 0 09:54 ? 00:00:01 /usr/bin/ibus-daemon --xim quanta 1946 1918 0 09:54 ? 00:00:00 /usr/lib/i386-linux-gnu/ibus/ibus-gconf quanta 1948 1918 0 09:54 ? 00:00:00 /usr/bin/python /usr/share/ibus/ui/gtk/main.py quanta 1951 1 0 09:54 ? 00:00:00 /usr/lib/i386-linux-gnu/ibus/ibus-x11 --kill-daemon quanta 1987 1918 0 09:54 ? 00:00:00 /usr/lib/ibus-unikey/ibus-engine-unikey --ibus I can make it appear by restarting the ibus-daemon: $ ibus-daemon -x -r -d I also have tried to add the IBus to the System tray whitelist but nothing changes.

  • sqlite3 timestamp (current_timestamp) one hour off

    - by Eiriks
    I run a small crawler on a virtual ubuntu server, initiated by crontab hourly. Datetime is inserted by defaulting the date filed to TIMESTAMP DEFAULT CURRENT_TIMESTAMP. Table creation looks like this: CREATE TABLE links (page TEXT, link TEXT, date TIMESTAMP DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY(page,link)); The datetime gets stored fine, but it one hour off (one hour behind) Norwegian time (GMT +1). The server is located where-ever, I just need it to be on GMT+1. By typing datein the ssh session I get: Wed Dec 19 17:26:02 CET 2012 and that is correct (just now). So where does sqlite3 get it's time from? What must I do to set the time so that sqlite3 gets the time right?

  • How do I import service references to Unity3D?

    - by Timothy Williams
    I'm attempting access a service reference in Unity. I need two: the SOAP framework and a separate service called ContentVault. The respective service URL's are: SOAP: http://api.microsofttranslator.com/V2/Soap.svc ContentVault: http://ioun.wizards.com/ContentVault.svc Both services import fine in to Visual Studio. I've tried everything I can think of but they won't work with Unity. I just get various errors (changing depending on which solution I'm trying out). I've attempted using svcutil to export the services as external scripts, but all I got was a bunch of using errors. I've tried converting the code to work with .NET 2.0 to no avail, I've even tried making the services in to .DLL's to no success. How could get these services working with Unity?

  • kile does not get keyboard input, respond to Alt+F

    - by vishvAs vAsuki
    I use 11.10 with Unity. I use two kde apps a lot - kile and kate. Since the latest upgrade, I have observed two problems: a] I can never use Alt+F to select the file menu (works with other apps), yet when I press Alt, kile's menu comes up in the status bar. b] A few times every day, while using kile (haven't used kate as much recently), the keyboard stops responding (just in the 'editor' portion, rather than in structure-tree navigation). I cannot enter any text, but mouse works fine. I usually restart kile to continue working. One inconsistent way to reproduce it (multiple times today): I cut text from one open document using Ctrl-X switched to another document in the same kile window using Ctrl-Tab, then this happened. c] Sometimes, in kate, I can type in the editor but the keyboard won't work in the 'File open dialog'. How do I fix the above?

  • Loading sound in XNA without the Content Pipeline

    - by David Gouveia
    I'm working on a "Game Maker"-type of application for Windows where the user imports his own assets to be used in the game. I need to be able to load this content at runtime on the engine side. However I don't want the user to have to install anything more than the XNA runtime, so calling the content pipeline at runtime is out. For images I'm doing fine using Texture2D.FromStream. I've also noticed that XNA 4.0 added a FromStream method to the SoundEffect class but it only accepts PCM wave files. I'd like to support more than wave files though, at least MP3. Any recommendations? Perhaps some C# library that would do the decoding to PCM wave format.

  • alsHigh CPU load - Ubuntu 14.04

    - by watt
    I noticed that sometimes when browsing (with other processes in the background), I get very high CPU load for the browser process (over 100%) and the computer becomes really slow. I tried switching from Firefox (with just a few extensions) to Chromium, but same thing happens without me visiting graphics-intense sites, flash sites or anything like that. I also noticed python or node (when running "make") produce the same high CPU load from time to time so this is not necessarily browser-related. When I only have a browser open, it doesn't seem to happen and everything is fine in Windows 7. I switched from unity to gnome3 with no effect. Specs: lenovo w510 (4gb RAM, i7 q820 @ 1.73) + up to date Ubuntu 14.04 64bit. Printscreen: http://imgur.com/8MZJNKC Do you guys have any idea why this might happen? Please let me know if there's other info you need. Thanks!

  • Nautilus will not launch after update to 12.10

    - by dereksalerno
    I updated to Ubuntu 12.10 today from 12.04 using the graphical update tool. Everything seemed to be fine until I went to open Nautilus, and it would not open. Bizarrely, I am able to open a file that I happen to have on my desktop, but when I click on the launcher, it never opens. When I enter 'nautilus' in the terminal, I get this: (nautilus:8557): Gdk-CRITICAL **: gdk_x11_display_get_xdisplay: assertion `GDK_IS_DISPLAY (display)' failed zsh: segmentation fault (core dumped) nautilus I am not a total novice with ubuntu or linux, but all I can tell is that there is some problem with X. Can someone please point me in the right direction as far as fixing this? I really don't want to have to do a fresh install. Thank you very much.

  • 301 url rewrite loop

    - by anyvendetta
    I need to do a 301 rewrite to force all urls to become lowercase i put in htaccess (RewriteMap lc int:tolower in httpd.conf) RewriteCond %{REQUEST_URI} [A-Z] RewriteRule . ${lc:{REQUEST_URI}} [R=301,L] Everything works just fine except to urls with subcategories which in this case are: /category-1256-Product-page-example.html the numer 1256 refers to a "subcategory" So when i try to access /category-1256-Product-page-example.html gives me a loop error message I think another redirect rules are making the loop but dunno how to fix it because are just this urls rewrite rules that don't work with the above rewrite.

Any help or old thread vaguely addressing this issue is highly welcome.

  • Bootable USB drive won't run installation

    - by Edgar
    I am having issues installing 12.10 on a laptop from bootable USB Drive 4GB FAT32. Also I changed order on BIOS to boot from USB. But only I see is the black screen with SYSLINUX 4.06 EDD 4.06-pre7 Copyright (C) 1994-2012 H. Peter Anvin et al _ I tried to install 12.10 into my older laptop using the same bootable USB drive just to be sure, and it's all works fine! I have also trying different USB drives, but results were the same. So it looks like there is nothing wrong with my bootable USB drives. Something is wrong with my laptop, but I can't figure out what exactly, because it's very new and Windows7 boots and runs just great. I Googled but found nothing useful. My laptop is really a small one: Acer AOD270 Protcessor: Intel(R) Atom(TM) CPU N26OO 1.60 GHz RAM: 1 GB Windows 7 Starter 32 bit It has no CD drive Any help would be really appreciated please.

  • Script to only execute during first install of a package

    - by Jeroen
    I recently started packaging up some of my software and publishing it on Launchpad. The installation and removal works fine, but upgrading the package form one version to the next version is problematic. The problem is that there are some scripts that only need to run during the first installation of the package. These scripts populate the DB, create a user, etc. They are currently called in the package.postinst configure) section. However this results in them being called during an upgrade as well as shown in the diagram. Is there a way to include a maintainer script in a .deb package that only executes during the first installation of the package and not during an upgrade? Or what would be an elegant way to include some initial setup scripts in a .deb package?

  • How do I make music sync with iOS 5 in Ubuntu 11.10 work?

    - by Alex Cristian
    I've tried several tutorials on the internet but nothing works. This is not a duplicate, it is true that there are several of them about ios5 but not one of them asks specifically about music syncing or ubuntu oneiric ocelot... I'm just so angry at Apple because of this, my iPod classic syncs just fine with Banshee but my iPad 2 won't, because they suddenly decided to change how uploading music to their app works in ios5. I looked around and saw that an unstable libimobiledevice-1.1.2. was available, but I can't manage to install it! It's a nightmare, any help would be greatly appreciated.
