• Switch keyborad layout hotkeys don't work on lockscreen

  - by svz

  I've recently upgraded to Ubuntu 13.10 which has a known bug that makes it impossible to change keyboard layout via Alt+Shift. I installed this patch which made it possible to switch layouts again. The problem I'm facing now is that it is still impossible to switch keyboard layout when I lock (Ctrl+Alt+L) system and press Alt+Shift. This way if I lock system with wrong layout enabled, I can't switch it to enter the password and unlock PC. I can still change layout by clicking on the layout indicator. I'll be thankful for suggestions on solving this.

• Can't access Ubuntu's shared folders from Windows 7

  - by endolith

  In Ubuntu Maverick, I've shared some folders using the Nautilus "Sharing Options" GUI. I can see them from Windows 7, but when I try to access them (from Windows) it asks for a username and password. No matter what I enter, it won't let me in. How do I configure this to share normally? Update: I've found that some of the shared folders let me in, but others don't. Of the ones that do, some of their subfolders do, others don't, etc. How can I investigate what's causing this?

• How do I install Java?

  - by Jay

  I am using Ubuntu 11.04 Natty Narwhal. I recently installed openjdk-jre6 because one of the websites I use requires java for me to log in. Unfortunately, even after installing openjdk-jre6, I am not able to use the website. In place of 2 text boxes where I am supposed to enter my username and password, it simply shows a message "click here to download plugin". I am using Firefox by the way. I even tried to install java by clicking on that message. But it says "Java Runtime Environment not available". And then gives me a button to install java manually. But I would rather install it from the repo's. Could someone please tell me, what I should do to get Firefox to take note of the openjdk-jre6 that I have already installed?

• CMS without templates

  - by Mark

  I am looking for a CMS where I can layout the page from scratch using HTML/PHP/CSS and simply enter code such as:- FOR EACH (listOfArticles) SORT mostRecent CATEGORY news LIMIT 5 <div class="articleTitle">{title}</div> <div class="arcielBody">{body}</div> END to get a list of the five most recent articles of a certain category in the relevant place. Does such a thing exist anymore? Unless my mind is playing tricks on me, the CMSs of five or ten years ago had this approach. I am thinking of MovableType and the now defunct CityDesk. It seems to me that CMSs these days have a 'templates first' approach. I.E. you must always choose a template before doing anything - which I find really painful. Learning how to design these structured templates also seems overly painful. So can anyone help me in my quest? Thank you, Mark

• Google Chrome would not exist fullscreen mode

  - by siberan

  I am running 64-bit Ubuntu 13.10, have latest stable google-chrome version 30.0.1599.114-1. Whenever I enter fullscreen mode by pressing F11, it would never exit this mode by pressing F11. Actually, I see it exit but then fullscreen mode is quickly restored. I searched for a solution, but nothing really helps. I even tried completely re-installing it with no luck. Any suggestions? Update: I tried completely removing ~/.config/google-chrome, it did not help. Update 2: I am running Cinnamon 2.0.6, maybe that would give some clues. Thanks, Nick.

• Rotating multiple points at once in 2D

  - by Deukalion

  I currently have an editor that creates shapes out of (X, Y) coordinates and then triangulate that to make up a shape of those points. What will I have to do to rotate all of those points simultaneously? Say I click the screen in my editor, it locates the point where I've clicked and if I move the mouse up or down from that point it calculates rotation on X and Y axis depending on new position relevant to first position, say I move up 10 on the Y axis it rotates that way and the same way for X. Or simply, somehow to enter rotation degree: 90, 180, 270, 360, for example. I use VertexPositionColor at the moment. What are the best algorithms or methods that I can look at to rotate multiple points in 2D at once? Also: Since this is an editor I do now want to rotate it on the Matrix, so if I want to rotate the whole shape 180 degree that's the new "position" of all the points, so that's the new rotation = 0 for example. Later on I probably will use World Matrix rotation for this, but not now.

• How to setup passwordless SSH access for root user

  - by Cerin

  I need to configure a machine so software installation can be automated remotely via SSH. Following the wiki, I was able to setup SSH keys so my user can access the machine without a password, but I still need to manually enter my password when I use sudo, which obviously an automated process shouldn't have to do. Although my /etc/ssh/sshd_config has PermitRootLogin yes, I can't seem to be able to login as root, presumably because it's not a "real" account with a separate password. How do I configure SSH keys, so a process can remotely login as root on Ubuntu?

• How do I unlock a user account?

  - by John Kotrla

  I've been to system settings and to User Accounts. My account is the only one on the system and I have previously been able to UnLock the screen so that I could set my account to login without password prompt. That didn't make any effect on the system. I still have to enter a password to log in, but now I can't unlock the User Accounts dialog to make any changes at all. What do I need to reset? note how the unlock box in the upper right hand corner isn't available for selection...

• Alsa version numbers not consistent

  - by user69245

  I've recently moved from 10.04 to 12.04 and have problems with crackles on audio when the screen changes (especially obvious in a Skype conversation with video). !!Kernel Information !!------------------ Kernel release: 3.2.0-26-generic-pae Operating System: GNU/Linux Architecture: i686 Processor: i686 SMP Enabled: Yes !!ALSA Version !!------------ Driver version: 1.0.24 Library version: 1.0.25 Utilities version: 1.0.25 Running through the SoundTroubleShooting procedures I got the above details at Step 3. Is the mismatch between the Driver version (1.0.24) and the Library and Utilities versions (1.0.25) the cause of my problem, or should I be looking elsewhere? In answers to the question "Will ALSA 1.0.25 version have time to enter 12.04?" I read that 1.0.25 would be part of the new kernel, but my kernel version appears to be newer than the original release.

• Instruct Ubuntu to boot TORAM from flash drive using unetbootin

  - by Goyuix

  I have used UNetbootin to create an installable / live bootable flash drive from Ubuntu 12.04. However that didn't preserve the normal Ubuntu boot menu which allows to me to enter advanced options. It has a custom menu that I can pick from predefined choices like "Install Ubuntu" and "Try Ubuntu without installing". What I would like is to be able to boot from the USB flash drive, but then be able to remove it from the computer once the desktop has loaded. The laptop I would like to use this on does not have a CD/DVD drive. What do I need to modify on the flash drive to add an option to "Try Ubuntu (RAM)" that passes the TORAM=yes parameter to the initrd options? Are their other things I need to touch/change as well? Bonus: I would guess the answer would also allow for other options like acpi=off as well, but if it is different I would appreciate having that answer too.

• ubuntu 12.04 nvidia breaks resolution

  - by Terje Kristiansen

  i am running ubuntu 12.04 64-bit and i have a nvidia Geforce GT 650m, it was running fine with 1920 x 1024, except a lot of tearing everytime i ran videos. I thought activating the nvidia driver maybe would fix this. When entering "nvidia X server setting" it says " you do not appear to be using nvidia X driver. Please edit your X configuration file ( just run "nvidia-xconfig" as root), and restart the X server. I did and then the computer reboots with a resolutioin of 640 x 480. How can i restore the previous settings, or preferably get it to show full resolution without tearing ? When i enter "nvidia X Server Settings" now it still says the same as above, " do not appear to be using nvidia X driver" when i go to "system settings, additional drivers" it says nvidia_current -- "This driver is activated but not currently in use" astr0

• How can I get a USB floppy drive to work?

  - by jfmessier

  I have a Toshiba USB floppy drive that I need to use under Ubuntu. When I connect it, and insert a floppy disk in it, I do not see anything mounted under Ubuntu 10.10. I was suspecting the hardware and/or the floppy disk to be defective, and so I tested the floppy disk as well as the floppy drive itself under Windows XP, and everything was just fine. I was able to find the following instructions: Add the following line to the /etc/modules file: floppy Enter the following shell commands: mkdir /media/floppy mount -t vfat /dev/sdc /media/floppy -o uid=1000 This will mount the floppy, but I would like this to happen automatically, so when I connect the drive to the USB port, it automatically mounts the floppy. How can I make this work? Or does Ubuntu only work with internal Floppy drives?

• How to disallow indexing but allow crawling?

  - by John Doe

  In the front page of my website, I have some previews to articles (with a small introduction to them) that link to the full articles. I want to disallow the front page to prevent duplicate content. But if I do this (in robots.txt), would it still be crawled? I mean, the full articles would be still reached by the crawler even though I disallowed the only page that links to them? I don't want the webcrawler not to access the page and enter the links in them, but I just don't want it to save the information (that will be repeated in the full articles).

• Interacting with IE using sendkeys from Excel

  - by Thomas Egan

  I'm trying to write an application which uses values from excel and then switches to a web application using sendkeys. The problem I am having is that I cannot used sendkeys ("{ENTER}") or sendkeys ("^o") as I don't have the access for that. I'm trying to automate a very trivial admin task. I've thought about using the mouse to interact with the links as well as pausing and waiting for the user to just hit return but so far have been unable to come up with a solution. Do you think there is anyway around this? I have some VBA knowledge (enough to get me this far) but not a great deal.

  - by user67966

  Well I have installed avast anti virus on Ubuntu 12.04. But after updating, it crashes! So I have made some tweaks like below: 1) I pressed press Ctrl+Alt+T and opened Terminal. When it opened, I ran the command below. sudo gedit /etc/init.d/rcS 2) typed my password and hit enter 3) when the text file opens add the line: sysctl -w kernel.shmmax=128000000 4) made sure the line you added is before: exec /etc/init.d/rc S 5) This is how it should look like: Code: #! /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 6) save it 7) 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.

• Mount and unmount errors when usb is connected in 12.10.

  - by Mysterio

  I just installed 12.10 and noticed some strange behaviour every time I connect a USB storage device. It reports I already have the device mounted by a different user but there is only one user account on this set up. Here is a picture of the dialogue: Also when I try to mount the inserted USB drive, I have to enter gain root privileges before the device will unmount successfully. Like this: . I can't copy/delete any file without root access either with the default file manager or third party file manager, Marlin. How do I resolve this rather frustrating experience? Thanks in advance.

• How do I keep track of modifications to a new server?

  - by eveo

  I purchased a server for the sole purpose of familiarizing myself with the CLI so I don't get royally screwed when I enter a real development environment. However, I have some questions. I've managed to SSH into my server, all is fine and dandy, installed LAMP too which went flawlessly. Now I'm wondering, the more changes I do, the more cluttered my server will become. Can I revert changes? I don't want to keep customizing things and installing things and just having a cluttered server overall. Where can I track changes to my system?

• Ubuntu 12.10 desktop/interface not showing on VirtualBox VM after login screen

  - by Jake

  I'm having some trouble with getting my Ubuntu to work on a VirtualBox VM. I made a clean installation of Ubuntu 12.10 on a VM without any errors. I arrive at the login screen, as soon as I press enter it does it's little loading thingy and then screen goes black, then this is all I get: http://i.imgur.com/zULUI.jpg I can access the terminal and pretty much all the other features through it, but I would like to have the GUI properly working. I've been looking around the web and looking at various fixes to similar problems, but can't seem to get it to work. I'm thinking this problem might have to do with the graphics? I'm running Windows 8 Pro as host, if that helps, might be some compatibility issues with VirtualBox in W8... Thanks in advance!

• Simple alternating text in Visual Basic 2008

  - by Josh Grate

  I have a simple completed program, but i would like to add one more feature to it but I'm not sure how. I have it set up to send a message automatically every 7 seconds when a text field is selected, repeating the message of course. What I would like for it to do is alternate between two separate messages, instead just repeating the one. I would like the new program to post at an interval of 12 seconds. Can you help me? Here is my coding. Public Class Form1 Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick SendKeys.Send(TextBox1.Text) SendKeys.Send("{ENTER}") End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Timer1.Enabled = True Timer1.Interval = (TextBox2.Text) End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Timer1.Enabled = False End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Timer1.Enabled = False End Sub End Class

• How to prevent a 404 Error when installing a subdomain using a wordpress multi-site installation

  - by Chris

  I have installed a multi-site instillation of WordPress onto my domain. I then added the necessary code to the wp-config.php file and .htaccess as instructed by WordPress. I also installed a plugin called Quick Page/Post Redirect Plugin which allowed me to place a 301 redirect onto the main domain as I only want to use the sub domain and not the main domain. Then I also added the following line of code to the wp-config.php file to redirect the main domain define( 'NOBLOGREDIRECT', 'URL Redirect Address' ); The site works fine with a redirect on the main domain and my subdomain runs fine when you type in subdomain.domain.com or http://subdomain.domain.com. However when I enter www.subdomain.domain.com or http://www.subdomain.domain.com the following error message is returned: Not Found The requested URL / was not found on this server. Apache/2.4.9 (Unix) Server at www.subdomain.domain.com Port 80 Any help with this would be much appreciated.

  I've been dual booting my system with Ubuntu 10.10 (Maverick Meerkat) and 11.04 (Natty Narwhal) but today after an update, I can't boot into 10.10, there's only option to boot into 11.04 and Grub also looks a bit different. Before this update, I used to see first option for 11.04 and an other option called /dev/sda1 for 10.10 but now there is a new option called Previous Linux Versions, but when I Enter into that menu, there is no option to boot into 10.10 all the options take me to 11.04 now it looks like this... And when I click on Previous Linux Versions...
