  • Log & monitor mysql databases on servers

    - by user3215
    How MySQL databases logged and monitored on ubuntu servers in real time?. I checked /var/log/mysql.log and found it empty. EDIT 1: The log was not enabled in the mysql configuration file. Now it logs and I could see the logs in the file /var/log/mysql/mysql.log But this could not be sufficient to gather additional information about the database logs. Is there any other way or any popular open source tool?

  • Best hardware for a Ubuntu Computer?

    - by Dante Ashton
    Hey all. I'll be needing a new PC soon, but I've decided to build my own, so my question is...what's the best hardware for Ubuntu? Specifically, in terms of graphics cards; I'm looking for something that will run smoothly (for Compiz's effects and Unity) but will be quite modern (IE: have a HDMI output) The machine itself is just a generic computer, nothing special; I just want to future-proof it. I'm looking at quad-core chips and 3-4 gig of RAM. I want something that will play nice with Ubuntu; now, and in the future... I used to build machines years ago, but I've fallen behind (that was in the Windows 98 era...so yeah, quite a while ago!) My main problem is the graphics card; I'd prefer to stick with NVIDIA, but only a tiny amount of computers I've seen play nice with Nouveau.

  • dpkg unsatisfied dependencies, now apt-get wants to remove whole system

    - by Bruno Finger
    firstly, I'm sorry for my terminal output in portuguese, but I guess it is still understandable. I am using Ubuntu GNOME 14.04 and I tried to update the GNOME Online Accounts packages by downloading the following .deb files from packages.ubuntu.com for the Ubuntu 14.10 version: libgoa-backend-1.0-dev_3.12.4-1_amd64.deb libgoa-backend-1.0-1_3.12.4-1_amd64.deb libgoa-1.0-dev_3.12.4-1_amd64.deb libgoa-1.0-0b_3.12.4-1_amd64.deb gnome-online-accounts_3.12.4-1_amd64.deb gir1.2-goa-1.0_3.12.4-1_amd64.deb After downloading them in the same folder, I run the command sudo dpkg -i *.deb, but it didn't install the packages, instead it showed errors due to packages which them depend doesn't meet the required version (and Ubuntu have no way to install them since they are not in this version's repositories). So now every time I want to install anything through apt-get, Ubuntu tells me to run apt-get -f install to fix the errors.

  • mpirun -np N, what if N is larger than my core number?

    - by Daniel
    Say I have a 4-core workstation, what would linux (Ubuntu) do if I execute mpirun -np 9 XXX Q1. Will 9 run immediately together, or they will run 4 after 4? Q2. I suppose that using 9 is not good, because the remainder 1, it will make the computer confused, (I don't know is it going to be confused at all, or the "head" of the computer will decide which core among the 4 cores will be used?) Or it will be randomly picked. Who decide which one core to call? Q3. If I feel my cpu is not bad and my ram is okay and large enough, and my case is not very big. Is it a good idea in order to fully use my cpu and ram, that I do mpirun -np 8 XXX, or even mpirun -np 12 XXX. Q4. Who decides all of these effciency optimization, Ubuntu, or linux, or motherboard or cpu? Your enlightenment would be really appreciated.

  • Wacom Bamboo CTH460L issues

    - by Robert Smith
    I recently bought a Wacom Bamboo Pen & Touch CTH460L. I installed doctormo's PPA, however, the pen functionality didn't work and the touch was very glitchy (when I touched it, it immediately double clicked and began to drag elements in the screen). I tried to configure it using the wacom-utility package in the Synaptic Package Manager (version 1.21-1) but that didn't work either. Then I followed this post (#621, written by aaaalex), and after some problems trying to restart Ubuntu (graphics related problems), the pen works fine (it could be better, though) but the touch functionality doesn't work anymore. Currently I have installed xserver-xorg-input-wacom (1:0.10.11-0ubuntu7), wacom-dkms (0.8.10.2-1ubuntu1) and wacom-utility. The Wacom Utility only displays an "options" field under "Wacom BambooPT 2FG 4X5" but no other option to configure it. What is the correct way to get this tablet working on Ubuntu 10.04?. By the way, currently I can't start Ubuntu properly when the tablet is connected (in that case, Ubuntu start in low graphics mode). I need to connect it later. UPDATE: I uninstalled xserver -xorg-input-wacom, and wacom-utility because one of them prevented Ubuntu to start normally. I only re-installed wacom-dkms 0.8.10.2-1ubuntu1. The pen is working but no touch functionality. The side buttons don't work either. Thanks in advance.

  • How do I get a Canon MG, MP and MX series USB printer working?

    - by Old-linux-fan
    Printer MP6150 driver installed itself upon plugging in the printer. Printer is recognized (lsusb shows it) but does not mount.

  • Security considerations for a default install?

    - by cpedros
    So with an old burned install CD of Feisty Fawn I went through the process of completely formatting the Windows OS and installing Ubuntu on an old XP laptop. I then went through the online upgrade to 10.4 LTS, only installing the gnome desktop environment package in the process. My (admittedly very open) question is that in this state and online, what security considerations do I have to immediately make for the default install? I understand that a lot of this swings on my intended use of the server, but just sitting there online what risks is it exposed to (this obviously goes far beyond the realm of linux, but I am not sure how these risks are accommodated in the default install). For example, I believe there is a firewall installed with Ubuntu but by default it allows all traffic. Any other guidelines would be much appreciated. Thanks

  • Gnome Do does not autostart and save shortcuts

    - by Matt
    For some reason the autostart of Gnome-Do will not work in 11.10. I've installed Gnome-Do via the Ubuntu Software Center. Then I changed the shortcut to launch Gnome-Do and marked the option to autostart Gnome-Do within Gnome-Do. In order to verify the autostart, I checked whether it's also found in the autostart applications (which it was). However, upon every restart I have to start Gnome-Do manually via the unity launcher and change the shortcut again.

  • Create bootable USB install image from command line?

    - by j-g-faustus
    I'm trying to create a bootable USB image to install Ubuntu on a new computer. I have done this before following the "create USB drive" instructions for Ubuntu desktop, but I don't have an Ubuntu desktop available. How can I do the same using only the command line? Things I've tried: Create bootable USB on Mac OS X following the ubuntu.com "create USB drive" instructions for Mac: Doesn't boot. usb-creator: According to apt-cache search usb-creator and Wikipedia usb-creator only exists as a graphical tool. "Create manually" instructions at help.ubuntu.com: None of the files and directories described (e.g. casper, filesystem.manifest, menu.lst) exist in the ISO image, and I don't know what has replaced them. (At my disposal is Mac OS X and Ubuntu server; I have neither Ubuntu desktop nor Windows.)

  • Ubuntu, Gnome, PAM and ecryptfs

    - by Michel
    I would like to have a directory accessible to a couple of users, and not readable by maintenance types ... I can do what I want using ecryptfs and a password known only to the "couple of users" in question, who then can mount the directory and use as they see fit. I would love to be able to automate that process and unlock the directory at login - again, only for the "couple users" in question, without asking a password. Gnome-keyring is able to store passphrases/passwords encrypted; and, apparently, if I could get a key identity to ecryptfs, Gnome PAM modules would allow the key with that identity to be unlocked, and the directory could be mounted. Alas, I have found no way to go from point A (Gnome PAM keyring module) to point B (use the unlocked key in ecryptfs). Another use of the same mechanism would allow to build a "key escrow" mechanism, where keys to encrypted volumes are safekept with, e.g., HR; so that company information in encrypted directories can be recovered if you pass under the proverbial bus.

  • BASH Scripting: Check If running with sudo/superuser, if not, dont run, return error

    - by EvilPhoenix
    This is something I've been curious about. I make a lot of small bash scripts (.sh files) to do tasks that I routinely do. Some of those tasks require everything to be ran as superuser. I've been curious: Is it possible to, within the BASH script prior to everything being run, check if the script is being run as superuser, and if not, print a message saying You must be superuser to use this script, then subsequently terminate the script itself. The other side of that is I'd like to have the script run when the user is superuser, and not generate the error. Any ideas on coding (if statements, etc.) on how to execute the aforementioned?

  • Window borders missing - gtk-window-decorator segmentation fault

    - by Balakrshnan Ramakrishnan
    I have been using Ubuntu for about 1 year now and I got a problem just two days ago. Suddenly I started experiencing a problem with the window borders (title bar with close, maximize, and minimize buttons). The problem : The window borders disappear I run "gtk-window-decorator --replace" For like 20 seconds everything is back to normal But it again returns to the problem. I searched over the Internet and found that my problem is similar to what is specified in this bug report: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/814091 This bug report says that the "fix released". I updated everything using the Update Manager, but still the problem remains. Can anyone let me know whether the problem is fixed? If yes, can you please let me know how to do it? I have already tried normal replace/reset commands like unity --reset unity --replace compiz --replace The "window borders" plugin is on in CCSM (CompizConfig Settings Manager) and it points to "gtk-window-decorator". I use Ubuntu 11.10 on an Intel Core2Duo T6500 with AMD Mobility Radeon HD 4300 graphics card. If you need more information, please let me know.

  • Problems Dual Boot

    - by user104108
    A few months I decided to install Ubuntu 12.04 on my PC alongside with my Windows 7 partition. In order to do that and avoid any mistake, I followed the steps of these tutorial: http://www.linuxbsdos.com/2012/05/17/how-to-dual-boot-ubuntu-12-04-and-windows-7/2/ Everything was going well until I decided to update to the 12.10 realese. I don't know what happened, but after I updated my Ubuntu, it stoped working, it didn't even launched, when I turned on my pc and choose to run "Ubuntu 12.04" on the Grub Screen, a weird messaged appeared. Well, so I decided to install the Ubuntu 12.10 and forget about the 12.04 partition, no problem. I erased the partitions used for the Ubuntu 12.04 with EaseUS partition Manager. However, when I start my PC, there is still the option of "Ubuntu 12.04" to chose, is that bad? And what about now, can I use the Windows Installer of Ubuntu ( http://www.ubuntu.com/download/help/install-ubuntu-with-windows ) to install the Ubuntu 12.10 ? What should I do to have Ubuntu 12.10 and Windows 7 in dual boot again? Thanks; Thales.

  • Wecam not detected

    - by Richard
    after much research ang googling, my web cam is still not recognized. In the time of Ubuntu 11.04 it was working fine. I did a fresh install of 11.10 and not more web cam. All the cheese and camera monotor and V4L tests and all failes with "cannot connect to /dev/video0" or equivalent. The output of 'lsusb' shows the webcam Bus 001 Device 002: ID 05a9:2640 OmniVision Technologies, Inc. OV2640 Webcam What I noticed is that neither /dev/v4l nor /dev/video* exists. If I re-install the v4l package all the /dev/video* are created, but no /dev/v4l If I reboot the /dev/video* are NOT created. I think the trouble is that the device are not created at boot time. I have a DELL Inspiron 1525 and until this fresh install the web cam worked fine. Can somebody help ? Thanks a lot Richard

  • Flash 10.2 RC + Crystal HD for HW accelerated video on Ubuntu

    - by Gee
    I have a netbook with a N450 Atom and a BCM70012 aka Crystal HD card. On Windows 7 I can play HD flash video with very little CPU usage because of the RC of Flash 10.2. I did some reading and saw posts claiming that the Crystal HD card is finally supported by the newer Flash 10.2 RC in Ubuntu but I can't get it to work. I can confirm that flash 10.2 is loaded and used, and there's even a HW acceleration option that is enabled in the settings but performance is horrible. From what I read, the Crystal HD card is supposed to be enabled on 10.10 by default - I don't know if it is. I tried installing drivers for it in various ways but HD flash video is still a slideshow So does anyone have it working? If so, how'd you set it up?

  • Installing Canon LBP6000 in Ubuntu 12.04

    - by MMA
    This is really frustrating. I am trying to install LBP6000 in Ubuntu 12.04 without any success. (Well, I had success about a week back when I first bought the printer and finally printed pages after a struggle of several hours. Then today it suddenly stopped working and I uninstalled everything and started from scratch. Now, I seem to have lost the way.) My steps Downloaded the latest Canon driver from Canon site. File Linux_CAPT_PrinterDriver_V240_uk_EN.tar.gz Got the radu script (I am allowed only two hyperlinks, so can not put the link here. You can Google radu Canon) Changed the /etc/modprobe.d/blacklist-cups-usblp.conf file as instructed in, Official Documentation. (See the section Ubuntu 12.04 Install). Now this file looks like, # cups talks to the raw USB devices, so we need to blacklist usblp to avoid # grabbing them # blacklist usblp Rebooted my machine Changed the port in radu script to 59787 as instructed in the link at step 3. (Again see the section Ubuntu 12.04 Install, or see the comment at How to Install Canon LBP Printers in Ubuntu. Also put the latest deb files from step 1 in the appropriate directory of this script. Ran the radu script. A printer, LBP6000 got added. Not two printers, one to be disabled, as appeared in the message on the terminal after running the script. sudo /etc/init.d/ccpd status shows, Canon Printer Daemon for CUPS: ccpd: 3142 3139 Results The printer does not print. Printer state (from System Setting-Printing, or at cups http interface localhost:631/printers/LBP6000) goes from Idle to Processing, a job appears in print queue, and then the job disappears and the printer state goes back to Idle. The actual printer does not even blink. Diagnostics (got help from the link in step 3, Troubleshooting) captstatusui -P LBP6000 shows communication error lsmod | grep usblp did not show anything. After running, sudo modprobe usblp, shows usblp 17885 0 However, ls -l /dev/usb/lp0 gives, ls: cannot access /dev/usb/lp0: No such file or directory /var/ccpd did not exist, created, sudo mkdir /var/ccpd sudo mkfifo /var/ccpd/fifo0 sudo chown -R lp:lp /var/ccpd Any suggestion will be appreciated. Do not know what to do.

  • MySQL fails to start after upgrade to 12.04?

    - by radek
    I'm a newbie on MySQL ground so bear with me. I've just finished upgrading 11.10 to 12.04. Everything seemed to work without any hiccups and all my software and settings are working fine. Apart from MySQL. When I try: sudo start mysql I receive an error: start: Job failed to start Where can I possibly diagnose what the problem is? And (hopefully) - how to sort it out? (I disabled automatic start following advice here if that is of some importance) Update 1: Both outputs of: cat /var/log/mysql.err cat /var/log/mysql.log are empty. Output of dmesg | grep mysql: [ 1401.785141] type=1400 audit(1335619832.181:25): apparmor="STATUS" operation="profile_replace" name="/usr/sbin/mysqld" pid=16165 comm="apparmor_parser" [ 1401.791089] init: Failed to spawn mysql main process: unable to execute: No such file or directory Update 2: As indicated by AWinter below - it seemed that MySQL disappeared automagically after upgrade and had to be reinstalled.

  • How to remove keyboard icon from keyboard layout indicator (to leave just the language abbr. alone)?

    - by Ivan
    I'd like to remove a keyboard icon, so replacing "[###] USA" as keyboard layout indicator to just "En", an English or American flag, or "USA" at least. How can I achieve this? UPDATE: When I've clicked to remove e-mail icon from the bar, keyboard language indication has disappeared also, and now I only see that useless keyboard icon, and don't see what language is selected now :-( I use Ubuntu 10.10.
