• Swap Mouse Buttons on startup

  - by andy boot

  This one bugs me. I fashioned this handy script to swap the left and right mouse buttons over: [My mouse is a Razer] /usr/bin/xinput set-button-map `xinput list | grep 'Razer' | grep -o \=[0-9]* | grep -o [0-9]*$` 3 2 1 4 5 6 7 8 1 10 11 12 13 When I run this in a Terminal it works. When I go to Startup Application Preferences - Add and then literally paste the above into the command field as an 'Additional startup program' It does not run on startup. Why not? I'm using Ubuntu 11-10 but this also applied to the 10-10

• Copy Ubuntu distro with all settings from one computer to a different one

  - by theFisher86

  I'd like to copy my exact setup from my computer at work to my computer at home. I'm trying to figure out how to go about doing that. So far I've figured this much out. On the source computer run dpkg --get-selections > installed-software and backup the installed-software file Backup /etc/apt/sources.list Backup /usr/share/applications/ to save all my custom Quicklists Backup /etc/fstab to save all my network mounts Backup /usr/share/themes/ to save the customization I've done to my themes I'm also going to backup my entire HOME directory. Once I get to the destination computer I'm going to first do just a fresh install of 11.10 Then I'll copy over my HOME directory, /etc/apt/sources.list, /usr/share/appications, /etc/fstab and /usr/share/themes/ Then I'm going to run dpkg --set-selections < installed-software Followed by dselect That should install all of my apps for me. I'm wondering if there's a way/need to backup dconf and gconf settings from the source computer? I guess that's my ultimate question. I'd also like any notes on anything else that might need backed up as well before I undertake this project. I hope this post is legit, I figured other people would be interested in knowing this process and I don't see any other questions that seem to really document this on here. I'd also like to further this project and have each computer routinely backup all the necessary files so that both computer are basically identical at all times. That's stage 2 though...

• Is this fix for Avast Antivirus crashing safe to use?

  - by TmRn

  Well I have installed avast anti virus on Ubuntu 12.04. But after updating, it crashes! So I have made some tweaks like below: Press Ctrl+Alt+T to open the Terminal. When it opens, run the command below. sudo gedit /etc/init.d/rcS Type your password and hit Enter. When the text file opens, add the line: sysctl -w kernel.shmmax=128000000 Make sure the line you added is before: exec /etc/init.d/rc S This is what it should look like: #! /bin/sh # rcS # # Call all S??* scripts in /etc/rcS.d/ in numerical/alphabetical order # sysctl -w kernel.shmmax=128000000 exec /etc/init.d/rc S Save the file. Reboot. My question is: Did I do anything wrong? I mean as I have made some tweaks, will it lower the security of Avast down like viruses do? Please if you are a programmer check this if it contains bug or harmful intentions... Thanks.

• How can I reinstall GRUB Bootloader on MBR after installing Kubuntu?

  - by Agnes

  I installed Ubuntu, but then installed Kubuntu over it (formated Ubuntu Partition) because Ubuntu is not compatible with almost any hardware on my PC. Problem is I'm stuck with an old GRUB that says Ubuntu in the options because in my attempts to make it compatible with my hardware I got an old Grub with an image with an Earth that says Debian. How can I replace the GRUB with the one Kubuntu is supposed to install. I don't want to modify just the text, or the command to install on /sdaX, I want to actually re-write the MBR with the latest grub (reinstall the bootloader). Thanks.

• Blank desktop after login

  - by Alex

  Today my 14.04 updated itself not requiring a reboot. After a while I rebooted because of other reasons and then I was pleasantly surprised by a blank screen. I have tried everything I could think about including Reinstalled compiz, unity, ubuntu-desktop, xorg Reinstalled and then removed the nvidia driver So far nothing has worked. Except for one little thing: my cairo-dock is showing. And that's all. I tried with Unity doesn't load, no Launcher, no Dash appears, but none of the answers there helped me. I also tried removing my ~/.Xauthority file and it still doesn't work. Does anybody know what else I could try? UPDATE: sudo dpkg-reconfigure xserver-xorg sudo service lightdm stop sudo service lightdm start When I run that code and then login again the icons on the desktop are displayed but the menu and the launcher are still not there. Also, when I try to run an application from CTRL + ALT + F1 such as dconf reset -f /org/compiz/ it says Cannot autolaunch D-Bus without X11 $DISPLAY I can only run applications with export DISPLAY=:0

• How to remove "Search and launch"?

  - by user38489

  Is it possible to remove the "Search and launch" whateveritis from my "desktop"? I've actually tried both Desktop and Netbook modes, but it stays there in both of them. I'm not afraid of editing files in the ~/.kde dir, but I would be really disappointed if this is the only way to do it. [more details/rants] I was able to wipe out several things but I've ended up with a black window that's movable (Alt-click) but not removable. Beside being surprised by the performances, I find Kubuntu extremely unfriendly, and I can't find the logic behind the items of the interface. I've tried to search for documentation, but what I've found is not updated and doesn't include the Netbook interface.

• Install Ubuntu 12.04 on Drive "D"?

  - by Bill Jones

  I have a Dell Inspiron 531S that originally came loaded with Windows Vista. A couple years ago I purchased a copy of Windows 7, formatted the hard drive and installed the updated operating system. In the process I formatted the 10 GB recovery drive partition on drive D as it was no longer needed for Windows Vista. I would really like to install Ubuntu 12.04 LTS alongside Windows 7 using the empty 10 GB drive D:. I have two questions. (1) Can Ubuntu be installed on a separate partition, a drive removed from the boot sector on drive C:? (2) If so would Grub be installed in the boot sector and properly select Windows 7 on drive C: or Ubuntu 12.04 on drive D?

• Graphics hardware warning when updating to 14.04

  - by pacomet

  As I use Ubuntu at work I just update only LTS versions but now I'm not sure if I can/should. As my computer is now ten years old I would change if was mine but as it is owned by my employer I have to work with it. It's not a bad one, it runs fine (this was not true when still had Windows on it ;-). When updating to 14.04, it warns about possible bad/slow performance with Unity 3D so I stop updating as I am at work, not my own computer. As I understand from http://askubuntu.com/a/438958/25305 Nvidia Geforce FX 5500 graphics card is still supported in 14.04. Now, in 12.04, I have driver version 173 and unity 2d runs fine for me. output of /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce FX 5500/AGP/SSE2 OpenGL version string: 2.1.2 NVIDIA 173.14.39 Not software rendered: yes Not blacklisted: no GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no Should I update? Is it better to stay with 12.04? Thanks

• Printing Off Center or Images Offset After Upgrade to 14.04 LTS (Brother HL-2240)

  - by fortitude

  :) I have a very frustrating problem with my Brother HL-2240 under Ubuntu 14.04. Bear in mind this was working perfectly under Ubuntu 13.10. In Firefox, when I print a webpage, all of the images are off center and cut off, this is a big deal for my work. In Google Chrome, when I print a webpage, the page is off center, toward the right margin. In Opera, when I print a webpage, all of the white areas within the margins are black, using a lot of toner. PDF opened in document viewer, prints off center. Steps I have taken to troubleshoot: 1) Playing with the printer settings, resetting to defaults, etc. 2) Un-installing the Brother driver and re-installing (linux-brprinter-installer-2.0.0-1 from the Brother website), which works perfectly in Ubuntu 13.10. I see a similar, un-answered question, here. Hopefully this question provides some additional clarity to the matter. If anyone would like some additional detail because she or he is willing to help, please let me know. I can scan output from the printer to show you. Thank you.

• Partitioning a 128GB SSD and 500GB HDD

  - by Gladen

  So I have a 128GB SSD and 500GB HDD. I want to reïnstall my laptop and put Ubuntu 12.10 on this setup. I already looked around on the internet and came up with this partitioning schema: about 2GB of swap on the SSD (I got 4GB of RAM in my laptop) / using the rest of that space /home on the HDD So I was wondering, are there any better schemes or extra partitions that I should consider putting on a particular drive? Thanks in advance! :)

• External Full HD monitor and Virtual Desktop Size

  - by Stefan

  I have two FullHD monitors attached to my ATI graphics card [2]. The resolution of both of them is detected properly without any modifications to /etc/X11/xorg.conf. I can run both of them in clone mode. However, when I try to run them next to each other, I got the following error: The selected configuration for displays could not be applied. If tried to fix this according to [1]. My xorg.conf now looks like this: Section "Module" Load "glx" EndSection Section "Screen" Identifier "Default Screen" DefaultDepth 24 SubSection "Display" # The 1088 is the smallest multiple of 32 >= 1088 # see manpages Virtual 1920 1088 EndSubSection EndSection This does not seem to be parsed properly. After restarting X, I cannot set resolutions beyond 1600 or so any more. /var/log/Xorg.0.log gives: [ 15.676] (II) fglrx(0): Not using mode "1920x1080" (width too large for virtual size) [ 15.676] (II) fglrx(0): Not using mode "1680x1050" (width too large for virtual size) Are my modifications syntactically incorrect? According to the man page, it should be fine. Any ideas?

• Dual boot Win/7 and Ubuntu 12.04

  - by Brian

  So I've always wanted Ubuntu along with windows 7 and finally I went to try and make my computer that last night. (( I'll just skip the long story. )) I loaded Ubuntu from CD, Version 12.04 and it loaded fine and then I clicked the install icon. It asked me witch option I would like to proceed with, and I answered Ubuntu, in Windows 7. So it did everything rather quickly, and restarted itself; upon restarting itself it ejected the CD, and I thought everything was good to go. It brought me to the Option to either load Ubuntu or Windows, I was thinking to myself wow that was alot easier than I thought; Windows 7 Loads fine after it checked the HDD but when I go to load Ubuntu it brings me to the loading screen and then stays there for a long period time, finally moves on as if it was going to load into the regular dashboard, but loads into a dos looking thing. (( I'm sorry if I sound retarded explaining everything I'm not great with computers )) And at the very time it says something like installation failed. It also says it could not find a file or something like that. If you need me to go back and get the full message and put it up here I will. But if I put the CD in it loads fine. Thanks in advance for everyone that helps me solve this problem.

• Rhythmbox - access Windows 7 Media Streaming

  I wish to be able to see and stream music to my Ubuntu 10.04 installation through Rhythmbox. I have enabled media streaming in Windows 7 and I can see Rhythmbox as an allowed device. I have installed the Coherence plugin for Rhythmbox. I can see my Windows 7 PC under the Shared folder in Rhythmbox, but I do not see any of my music. Is there a step along the way that I missed or something else that I have to enable?

• How can I limit CD drive speed while on the live CD to avoid drive noise?

  - by iugamarian

  I sometimes disconect my harddisks for the weeks while only using the internet and I use the Ubuntu Live CD. But every time it needs something while in live desktop it accelerates and makes a lot of noise, also the acceleration takes too long. I want lower drive speed than acceleration lags, because acceleration lags stop me completly exactly when I need something. How can I lower the CD drive speed, say to maximum 16x, without restarting? I can't restart because I only use the CD drive, no harddisks, no flash disks, no network disks. Edit: No USB drives. Setcd does not work for the live session.

  I have a problem with the MATLAB 2012 installation. After having installed it using alt+f2 and having used gksudo nautilus I have installed MATLAB in the correct folder which is: /usr/local/MATLAB/R2012a Then I inserted the license and the window told "activation complete" or something like that.

• HELP: I Broke Ubuntu By Uninstalling Compiz

  - by tSquirrel

  I'm still getting used to Linux, having come from Windows. I was receiving an error that "compiz" had crashed a few times so I figured I'd uninstall it. sudo apt-get remove compiz sudo apt-get install compiz I logged out then back in, after that, the GUI was totally gone and I have no idea how to get it back or what I need to do to restore the GUI to what it was before I killed poor Compiz. GUI was pretty much unmodified after a fresh install of 14.04 How can I fix it? I'm not even sure how to get to a terminal or anything. The login screen looks normal, but after logging in, it's a totally bare desktop with my backround and a few icons. No Dash, toolbar, etc. Hot Keys don't seem to work either (Super = Dash doesn't work, etc); although I did accidently open "Disk" UI. Not sure how. Please Help! Right now I'm working off my W7 dualboot.

• how to bind super+s to indicator applete complete? - gnome classic

  - by rrosa

  i use gnome classic, i'm not a mouse fan. when i get an email while i'm writing code, i i would super+s to get to the indicator-applet-complete and read it. also to write emails, or check unread instant messages. upgrading from 12.04 to 14.04 made super+s bind to applications menu rather than the indicator applet complete. i removed the binding from the applications using dconf-editor, navigating to: org-gnome-desktop-wm-keybindings and disabling (['disabled']) the panel-main-menu key. now, how do i bind super+s to the indicator applet complete? it seems to be some how binded, since if if press super+s and then move the cursor over the applet it'll open the drop down menus (and it won't if i hover without pressing super+s) but i don't want to have to use the mouse...

• Lost volume control OSD for Ubuntu

  - by Vultan

  I've been happily chugging along with Ubuntu 14.04 (love it), and something I must have done removed the on screen notification when I change the volume via keyboard buttons. When I change the volume via the keyboard, it works, I can hear the alert telling me I've done it, and the small volume indicator in the panel does show the change, but I used to see a pop up rounded rectangle in the top right of the screen that showed me clearer feedback when I changed volume via the keyboard. It's now gone. Can anyone offer any help in bringing it back?

• Dropbox install stuck at 99%, how do I fix it? (and any dpkg errors)

  - by John

  I tried to install Dropbox using How to install Dropbox?, or with apt-get install nautilus-dropbox. Dropbox loads until 99% and then hangs, causing the system to go to 100% cpu usage. If I reboot or close the terminal, I sometimes get dpkg errors which prevent me from using apt-get or Software Center to perform any package management functions. I would like to resolve all these and just get Dropbox working. How do I do that? Note: This question is possibly answered in two parts: The accepted answer tells you how to install Dropbox. But if you have dpkg errors, see this answer before you use answer 1 to install Dropbox.

• How to re-enable tray icons for applications in ubuntu 13.10?

  - by andraaska

  Unfortunately in new Ubuntu 13.10 there is no Tray Icon and Whiteliting is removed. The older solutions are not works for me, e.g.: No such schema 'com.canonical.Unity.Panel' message answered when I try to use the gsettings set com.canonical.Unity.Panel systray-whitelist "['all']" comand. How can I get tray icons back (for applications that put icon in tray like Truecrypt, Pidgin, Aqualung, gnome-system-monitor, gyache, and so many more...) in Unity ? The most annoying is that the user loses control over applications can not detect itself that it has no tray icon... (e.g.: gnome-system-monitor, truecrypt...) At least Aqalung send a message about unable to put icon on systray! Thanks

  I'm using a lubuntu desktop, distribution Ubuntu 13.10, i686. This is my problem: in the job list scheduled by cron a job hasn't effect, but in /var/log/syslog its execution is traced.
