• How will the launcher/button work on a touch panel?

  - by burli

  I'm not sure if Unity has a design problem. If the Launcher is hidden you can bring it to front by moving the mouse over the home button or hit the Super Key. So far, so good. But what is on Tablet Devices with touch panel? Intuitively I would "click" in the corner to show the launcher, but a click will open the Dash. How should that work on a touch device? Do I have to "drag" my finger into the corner? Will touch devices have a "menu button"? Will there be a gesture to show the launcher?

• Software Center doesn't ask for a password anymore

  - by Jeff

  So, out of the blue, software-center stopped asking me for a password. It just runs, and then turns grey. Works fine as root, or with sudo. While investigating, I found out about polkit (new to me), and looked at the policies, which seem fine. Looking under localauthority, however, showed that while the sub-directories (10-, 20-, 30-, 50-, 90-) are there, there aren't any files under those. Is that my problem? Should there be a file in the 50-local.d? Or am I still looking in the wrong place for my problem? I looked for similar questions and looked at the answers, but they don't really help any. One other thing, I'm not sure it's related but seemed to happen about the same time: The Dash Home only shows items for recent files and downloads. Nothing anywhere else anymore.

• Screen will not lock automatically 12.10

  - by swalker2001

  Since upgrading to 12.10 I cannot get my screen to lock automatically. I am using GDM at home and LightDM at work and neither will lock automatically. However, when I issue CTRL + ALT + L on either system, the screen will lock as it should. It is set to turn the display off after 5 minutes and lock screen when screen turns off. Require Password is set also. Display turns off after 5 minutes but no locking occurs. I am using Unity with Compiz on both systems. Not sure what other things might be involved.

• Windows: starting sqlplus in new window from cygwin bash

  - by katsumii

  When I start sqlplus, more often than not, I want it to start in new window,whether it be on Linux/Solaris GNOME or Windows.I seldom use GNOME so I never bothered to figure out how.On Windows, one can use Windows menu or Win+R "Run" dialog but I prefer usingbash. Because, this way, I can keep the history in ~/.bash_history file.There are 2 ways. Using cmd.exe or cygstart.For example, to start default sqlplus.exe to connect to default local instance. $ cmd /c "start sqlplus sys/oracle as sysdba" 2nd example. To start sqlplus in 2nd Oracle home and to connect to non-default local instance. $ ORACLE_SID=orcl cygstart /cygdrive/g/app/product/11.2.0.3/dbhome_1/BIN/sqlplus scott I hope this tip helps reducing your DBA time.

• How to install flareGet_1.0-1(beta)_deb_rpm.tar.gz?

  - by Suhail cholassery

  I have lot about Flareget download manager and I wanted to install it in my computer. I visted the website and dowloaded the the file flareGet_1.0-1(beta)_deb_rpm.tar.gz and saved it in the location /home/suhailcholassery/Download/flareGet_1.0-1(beta)_deb_rpm.tar.gz. The thing is that I am new to Ubuntu and don't know how to install it. I tried typing the following command in terminal as per the readme's instruction enclosed in file. yum install flareGet-1.0-1.i386.rpm, but the reply was the following: You need to be root to perform this command. And I don't know how that is to be done. Isn't there any simpler way for installing this package?

• Gigaom Article on Oracle, Freescale, and the push for Java on Internet of Things (IoT)

  - by hinkmond

  Here's an interesting article that came out during JavaOne which talks about the Oracle and Freescale partnership, where we are putting Java technology onto the Freescale i.MX6 based "one box" gateway. See: Oracle and Prosyst team up Here's a quote: When it comes to connected devices, there’s still plenty of debate over the right operating system, the correct protocols for sending data and even the basics of where processing will take place — on premise or in the cloud. This might seem esoteric, but if you’re waiting for your phone to unlock your front door, that round trip to the cloud or a fat OS isn’t going to win accolades if you’re waiting in the rain. With all of this in mind, Oracle and Freescale have teamed up to offer an appliance and a Java-based software stack for the internet of things. The first version of the "one box" will work in the connected smart home, but soon after that, Oracle and Freescale will develop later boxes for other industries ranging from healthcare, smart grid to manufacturing.

• Quick path jumping

  - by Sebastian P.

  I was just at a lecture, where I noticed the lecturer using a command (probably aliased) to jump to a specific folder. Example: ~/code$ j sciproj ~/projects/sciproj2011/$ This looked quite slick, so I started wondering: Is this a standard utility, and if so, what is the name? I have two theories as to how it works: It can both create, delete and jump to aliases directly from the command-line in the style of the example, without having to set up aliases in a configuration file or script or whatnot manually. It searches the home directory for a folder matching the name and jumps to it. The second option seems a bit slow, however, so the first would be preferred.

• How do I make Unity quit opening Firefox under the Shiretoko icon?

  - by Azendale

  I'm using Ubuntu 12.04, and whenever I open Firefox, whether it is from searching on the dash or clicking a 'quick-launch' launcher, it always opens yet another icon for the running instance that is a blank page and says Shiretoko. It will pulse the Firefox icon for a while (I'm guessing until a timeout or something). It's as if Unity no longer recognizes the Firefox process as Firefox and misidentifies it as Shiretoko. (I know Shiretoko was a testing version of Firefox a long time ago.) How do I set Unity straight? I imagine that it has something to do with me once using Shiretoko, but I believe that was even on a different installation, just the same home folder. Is there some place Unity caches this information that I can clear (or remove specific parts of)?

• Places Folders Open in Archive Manager

  - by PansophySR

  Am relatively new to Ubuntu. Currently running 10.10, which was an upgrade from 10.4, which was an upgrade from 9.10, which was a fresh install. Have never compressed anything in Ubuntu, but because I wanted to use the contents of a large folder on a Windows machine, I installed 7zip. Using Places, I navigated to the folder I wanted to compress, right-clicked, chose Compress, selected 7-zip and started the compression. This took many minutes to complete (the final 7z file is over 2.2 GB), but when I copied it to the windows machine, 7-zip handles it fine. However, now when I open Places, the Home Folder, User folder, Documents, Music, Pictures, Videos and Downloads all open the Archive Manager which gives an error message that it "Could not create the archive" because the "Archive type not supported." If I open Places/Computer choose the usr folder from places on the left and right-click/Properties on any of the folders, Music for instance, there is no place to change the "open with." Anyone know how to get this working again.

• Windows Not Sleeping All Night

  - by John Paul Cook

  Having a computer wake up when you don’t want it to wastes electricity and drains the battery on mobile devices. My desktop had been waking up at night, so I assumed it was some network traffic on my home network. I unchecked Allow this device to wake the computer on my network adapters . Figure 1. Network adapter Power Management tab. That didn’t solve the problem. I included the screen capture in Figure 1 because it could be part of the solution for someone else. To identify the root cause instead...(read more)

• Pidgin unable to connect to GTalk

  - by user42933

  I can't believe I'm raising this question after years, but after a fresh installation of Ubuntu 12.10, I'm unable to connect Pidgin to Google Talk. I use a Google Apps domain name, and the settings that I'm using are : Protocol : XMPP Username : **** Domain : ********.com Resource : Home In the advanced tab, Connection security : Require encryption. UNCHECK Allow plaintext auth over unencrypted steams Connect port : 5222 Connect sever : talk.google.com File transfer proxies : proxy.eu.jabber.org Bosh URL : (blank) In the proxy tab, No proxy. I had used these same settings on 12.04 and it had worked like a charm. Any help will be appreciated.

• Recovering user files with a Live CD

  - by user33617

  For some reason my bootup isn't working. I get an error akin to "Operating System Not Found". So I tried bootrepair, and that didn't work. So then I decided I would just save my personal files, wipe everything, and reinstall. Except when I go to the /home directory, my username folder isn't there, instead it goes to the Live CD's desktop and file folders. Is there some other error occurring? Is there a way to recover the files?

• Embeding a generic google search with autocomplete - not a custom site search

  - by picxelplay

  Most people's home page is google.com. My homepage is just a custom html page hosted on my computer. I do this because I am a web developer, and I have several projects that I work on a one time, so I like to have quick links to all of them. On that page I usually just have a Link to google.com for when I want to search. But below all of my quick links, I want to add a google search box (with Autocompletions). I first used a simple iframe to embed google.com into the page, but then my search results were confined to that iframe. I wanted to search for something, then my results would open in a new tab. I then came across this code snippet but it doesn't have Autocompletions: http://www.refactory.org/s/google_search/view/2 How can I add Autocompletions to this? Or is there a better way of doing it? Thanks in advance for any advice

• Inserting Data into a Microsoft SQL 2008 Database in ASP.NET 3.5

  In the previous article Creating an ASP.NET Dynamic Web Page using a MS SQL Server 2 8 Database GridView Display you learned how to create a dynamic web page that can let the user edit and delete database records directly using a web browser. It was demonstrated with a home renovation project where team leaders can update and delete project tasks online. However it does not include features that let users add or insert new records directly into the database using a web browser. This feature will be covered in this tutorial....

• Ubuntu boots into terminal

  - by DKuntz2

  When I turn on my computer (a CR-48), I keep loading tty1. I have tried xstart, and all I get is: Fatal server error: Could not create lock file in /tmp/.tX0-lock When I attempted to make the directory (both sudo and not), I received these two errors: sudo: Can't open /var/lib/sudo/don/tty2: Read-only file system (I've gotten other tty's for different virtual terminals) mkdir: cannot create directory '/tmp/tX0-lock': Read-only file system Before I got to the only terminal state, I had the computer moving a few files from a network server to the computer, I put it to sleep without stopping the transfers, and started the computer again away from my home network, and attempted to stop the transfers, the computer than restarted. Running sudo reboot puts me right back in the virtual terminal, and I can't get into any sort of x application.

• Has an open console any chance to give more strength to the indie game world ?

  - by jokoon

  I have heard about the GPX, but i don't really think the embedded market is mature enough in terms of performance, but what about the home console market ? I'm not talking about last-generation graphics, because that would be economically impossible, but what about an hardware as fast as a playstation 2/Xbox 1/Gamecube ? For games, the trick would be to ask some editors to recompile their best sellers for the new machine: those games being from the PSX age or even older console generations, I think this would have a very low cost job and they could still make some good profit, but I need to know if this is doable technically, considering the architecture which can be quite exotic. Do you think it would be a viable project to talk about to investors ?

• mount remotely mybook live network drive

  - by bob

  I have a mybook live western digital 1TB hard disk connected to fritzbox 7270 router in office. When I am in the office, I can mount this drive to ubuntu since I have added to the etc/fstab file: //192.168.178.30/user /home/user/DISK cifs auto,iocharset=utf8,user=user%password 0 0 Is there a similar, easy & safe way, to do the same when I am out of the office using the static IP of the fritzbox router? I have already added tcp port forwarding in the router for ports 8080 (to 80 of the disk) and 8443 (to 443 of the disk). Thank you in advance

• How do I reset the default icons from the desktop icons?

  - by Jens Reubsaet

  I know this question sounds cryptic, but what I mean is this: I set different icons for the 'home' and mounted volumes on the desktop, but I want to revert that action. How do I do that? I already tried to do it from the icon selection dialog by clicking revert, but no effect. How do I restore this? (the desktop icons are from the default GNOME Icon Theme but I have the Faience icon theme: these do not really match up). Thanks in advance! I'm running Ubuntu-GNOME 13.04 64-bit (GNOME 3.8.2) I set the icons by right clicking, clicking the icon and selecting it by the dialog.
