  • How do I reset my display settings from the command line?

    - by Trevor
    I'm running 12.10 on a dell e5400 laptop and I used xrandr to get the dual monitors working that I connect through a laptop dock. I used xrandr again to switch back to the laptop display when I undocked. The problem is, after a restart, the laptop seems to want to come back up with the dual monitor configuration and the laptop screen stays blank. I can boot into single user mode but I'm not sure what to do from there to get the display settings reset. Any ideas? There's no xorg.conf file so I'm not sure where the settings are stored anymore. Thanks.

  • Itty bitty ITTIA DB for Java Embedded Device Development

    - by hinkmond
    Here's a nice 3rd party itty-bitty database, called ITTIA DB, for Java Embedded and Mobile development See: ITTIA DB for Java Embedded Here's a quote: Java applications on mobile devices and other embedded systems can now leverage the robust shared access and data distribution features of ITTIA DB SQL with a new JDBC (Java Database Connectivity) driver released this week. This driver provides significant value for Java developers targeting embedded platforms such as QNX and Linux. Plus, it can exchange data with an Oracle back-end database. That's good if that's what you have on the back-end. Hinkmond

  • Reboot only shuts down and doesn't actually boot again

    - by PherricOxide
    I'm running a fresh install of Ubuntu 12.04 Server on an abmx rack mount server. When I attempt to reboot with sudo shutdown -r now, the machine just shuts down and doesn't come back up without me manually pressing the power button. The output of last -x, runlevel (to lvl 2) 3.2.0-29-generic Wed Oct 31 14:32 - 14:37 (00:05) reboot system boot 3.2.0-29-generic Wed Oct 31 14:32 - 14:37 (00:05) shutdown system down 3.2.0-29-generic Wed Oct 31 14:30 - 14:32 (00:02) runlevel (to lvl 6) 3.2.0-29-generic Wed Oct 31 14:30 - 14:30 (00:00) This appears to show that the system rebooted, but it went dark (no power lights, BIOS, etc) and I had to go press the power button in order to make it boot back up. The machine does have some sort of Intel Boot Agent that usually appears before the BIOS, I'm wondering if it could be causing this. I'm not sure what information is useful for debugging this, but I put the output of lshw in http://pastebin.com/mBy72kTQ

  • Compiz Error After Emerald Install

    - by KoopaTroopa
    Salutations! So, once again, I fell to the allure of the window decorator emerald. Where, just like the first time around, (I know I know) upon attempting to back out of emerald to the safety of compiz I'm faced with a problem. Seemingly after several minutes or after opening Chrome any window that isn't maximised has it's borders removed (so there's no close, minimise and maximise etc buttons). I can get them breifly back if I reload compiz via fusion-icon. After a brief chat on IRC it appears compiz is crashing. Here's a pastebin log of me running compiz via terminal. http://pastebin.com/sK65v4Fi I forgot my two vows of 'Never bother using Windows applications via wine or a VM' and 'Thou shalt never not use compiz'. ***GTK-Window-Decorator log gtk-window-decorator (gtk-window-decorator:11027): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap", Segmentation fault ** also posted on ubuntuforums to widen my scope of help.

  • Desparately Need Help: After a mishap, a folder shows 0 files in it

    - by bobby
    I'm hoping some of you guys may be able to shed some light on this scenario: I had a odt document on which I was working from one of many files in a folder among many on an internal hard-drive. Some kind of glitch occured and the document crashed (this could have been some kind of power charge whilst another hard drive was being unmounted). As I looked into the folders surrounding the folder in which my odt document was stored, they start to show 0 files in them. I immediately switched off the PC and then re-started. Upon the re-start, the folders would show the 1,000s of files I've stored in them and then within 5 minutes, as I started to back them up, freeze, cut-off the process of transfer. When I tried to open anything on the internal hard-drive, be it an avi film, an mp3, a cbr or a word doc, they all showed blank or would work. Some folders had vastly less files showing. Eventually, things calmed down. I closed the PC, checked that the connections were in firmly, gave it a vacuum and restarted the PC. All the files eventually showed up and I started to back them up (which I'd brought a hard drive for anyway but been distracted and not done). All folders show except the one which contained the document I was working on at the time of the trouble. Strangely, it was one that should itself full on several occasions on restarts. It shows zero files now. Properties shows zero files and zero space taken by it. Yet when I drop a file into this folder by pasting it in, it disappears too. Opening the folder, there is nothing there. But if I paste that document again, the PC asks would I like to replace the existing file with the same name (that I can't see), when I click yes, the file appears. When I exit, the folder shows the 0 files in the folder. Going back into the folder, it has disappeared again. I'm hoping that someone can help give me tips to recover the files in the folder, it would be greatly, greatly appreciated. All other films, music, comics, documents show and are fine!

  • Unable to remove network proxy

    - by Rushil
    I'm on 11.10 I'd set up a network proxy a couple of days back from system settings .And afterwards I'd set my proxy method back to none. However, my proxy has not been removed. I know this because: a: 127.0.0.1 routes me to the index.html file in the base directory of the proxy server. b: I'm able to access my university internet after hours. I checked my /etc/environment and etc/apt/apt.conf file and both of them have no proxy details. I also tried resetting the proxy and then getting rid of it but that didn't work either.

  • "Best fit" to avoid reuse of object instances in a collection

    - by Simon
    Imagine I have a collection of object instances which represent activities for a user to undertake. Dependent on user attributes, I have to randomly select instances to present activities to the user. For some users, I need to present more activities to them than there are available activities in which case, I want to use the following algorithm. If all available activities have already been presented to the user, then re-select a "used" activity, selecting the earliest presented activity ordered by frequency of use. In other words, try to reduce repetition and where repetition is unavoidable, use the instances which have been repeated less often and were presented furthest back in time. Before I go on to code that algorithm, I wondered if there is some existing pattern I can re-use? [EDIT] "Furthest back in time" is not relevant as I will pass the algorithm an ordered collection of used instances where the first entry is the first presented.

  • Synaptics touchpad sensitivity. Issue?

    - by Dave
    Just installed 12.04 LTS and I experience some problems with my touchpad. Everytime I tap/double tap the touch the cursor is moving around (not static as should be) (for example if I want to close a window, I click on "x" button from touchpad, the cursor is moving and not always hit the "x" button). Touchpad buttons left click, right click are working well, but tap not. Did u guys experience the same problem? Is there something related to sensitivity? How to fix it? PS: on Ubuntu 11.10 didn't had this issue

  • Systray Icons missing after App Crash

    - by pr0ndigy
    After installing Alarm Clock (alarm-clock) from the Software Center, the program immediately crashed and made the icons in my systray disapear except for Power, Sound, Time/Date, and the Gear. I tried logging off, rebooting, removing the program, and nothing has brought my icons back. I know they are still running up there, because i got Skype setup to autostart and it had an icon up there running before i installed the Alarm Clock program. Is there anything i can do to get my icons back, or do i need to reinstall the OS? I'm running Ubuntu 14.04.1 btw...

  • Catalyst forgets monitor settings after reboot or log out in 12.10

    - by Mate Weisz
    I have a Samsung monitor connected to my ATI Radeon graphic card via HDMI. By default the screen has a black border around, but I can disable it in the Catalyst menu to get full screen. (There is a scalebar that I have to set to the highest value.) My problem is that every time I turn off and on my computer it changes back and I have to set it up again. It is really annoying. Is there any way to make this setting permanent? Notes: 1. I open Catalyst with admin rights. 2. When I open the Catalyst settings menu, it looks like that it keeps my settings, because the scalebar stays at the highest point, but still it doesn't scale up my screen until I move back and forth the scale bar to the same point

  • How can I get my wireless webcam to work?

    - by hellocatfood
    I recently bought this wireless webcam. I'm having trouble getting it to work on Ubuntu 11.04. I ran lsusb and got the folowing information about the device Bus 006 Device 003: ID 0416:a91a Winbond Electronics Corp. I did a Google serach for teh device ID and this website informs me that it matches the LogiLink Wireless Webcam (so Maplin probably just rebranded this!). What this website states is that this device should work, which it doesn't. The problem I'm facing is that I don't get any actual video being streamed or shown. The built in microphone works and, when running Cheese, when I press the camera button on the webcam itself the software recognises that the button is pressed. On that note, when running cheese from the terminal with this webcam attached I get the following error libv4l2: error getting pixformat: Invalid argument libv4l2: error setting pixformat: Input/output error Any help is appreciated

  • A bacon- (and module-) saving PowerShell incident

    - by AaronBertrand
    Earlier today I made a big goof. I opened a module in Notepad, intending to use it as the basis for a new module. I was in the process of using "File > Save As" when my phone rang just at the precise instant that, for some reason, made me click on "File > Save" by mistake. After hitting Ctrl+Z 30 times to try to get the old version of the module back, I remembered that Notepad has never had more than one level of Undo. Back when I was coding ASP by hand, I was very well aware of this, but I...(read more)

  • How do I get to the maintenace shell?

    - by Narida
    I'm asking this because initially, my problem was this (power failure during installation, so I typed the following instructions in the maintenance shell: sudo mount -o remount,rw / sudo dpkg --configure a sudo mount -o remount,ro / sudo sync sudo reboot The first three lines worked, afterwards, my computer (a Dell Inspiron 530) got stalled for several hours, so I unplugged it. When I turned it on, the log in screen appeared, and after I try to write my password, it leads me back to the log screen. I must note that when I typed the first three lines during the maintenance shell mode, it said that the errors which were encountered during processing were: initscripts bluez gnome-bluetooth So, what do I have to do in order to get back to the maintenance shell so I can type code again? And, what code do I have to write in order to restore my computer? Thank you for your attention.

  • Photo and Video backup [closed]

    - by MyNameIsTooCommon
    Apologies if this is the wrong forum. Please move if necessary I want to back up all my photos and videos online. Some videos are HD and up to 2GB in size. Does anyone know of any good sites? Flcker and Picasca seem the obvious ones but there seem to be limits on size. I have also heard bad things about the Picasca UI. I basically want to remove most of the photos from my laptop HD and then sync with web when I want to download them. Viewing via mobile is not a big thing for me. I just want somewhere save to back up stuff. Thanks

  • Capture a Query Executed By An Application Or User Against a SQL Server Database in Less Than a Minute

    - by Compudicted
    At times a Database Administrator, or even a developer is required to wear a spy’s hat. This necessity oftentimes is dictated by a need to take a glimpse into a black-box application for reasons varying from a performance issue to an unauthorized access to data or resources, or as in my most recent case, a closed source custom application that was abandoned by a deserted contractor without source code. It may not be news or unknown to most IT people that SQL Server has always provided means of back-door access to everything connecting to its database. This indispensible tool is SQL Server Profiler. This “gem” is always quietly sitting in the Start – Programs – SQL Server <product version> – Performance Tools folder (yes, it is for performance analysis mostly, but not limited to) ready to help you! So, to the action, let’s start it up. Once ready click on the File – New Trace button, or using Ctrl-N with your keyboard. The standard connection dialog you have seen in SSMS comes up where you connect the standard way: One side note here, you will be able to connect only if your account belongs to the sysadmin or alter trace fixed server role. Upon a successful connection you must be able to see this initial dialog: At this stage I will give a hint: you will have a wide variety of predefined templates: But to shorten your time to results you would need to opt for using the TSQL_Grouped template. Now you need to set it up. In some cases, you will know the principal’s login name (account) that needs to be monitored in advance, and in some (like in mine), you will not. But it is VERY helpful to monitor just a particular account to minimize the amount of results returned. So if you know it you can already go to the Event Section tab, then click the Column Filters button which would bring a dialog below where you key in the account being monitored without any mask (or whildcard):  If you do not know the principal name then you will need to poke around and look around for things like a config file where (typically!) the connection string is fully exposed. That was the case in my situation, an application had an app.config (XML) file with the connection string in it not encrypted: This made my endeavor very easy. So after I entered the account to monitor I clicked on Run button and also started my black-box application. Voilà, in a under a minute of time I had the SQL statement captured:

  • Backing up VPS and Database Servers for website

    - by TravisK
    I currently have an "un-managed" (no help from hosting company) windows vps server. I am working on a good backup solution to return my site back online within a few hours. I am pretty comfortable backing up and restoring my database, however what is a good solution for backing up my VPS for easy recovery? Should I just use windows backup and create an image? I'm open to suggestions. Additionally, has anyone had to restore an entire VPS before? Is it reasonable to have it back up and running in a few hours?

  • 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 can I always show the close, minimise and maximise buttons on their windows and keep global menus?

    - by sup
    First, this is not a duplicate of How can I always show the close, minimise & maximise buttons into their own windows? - I would like to preserve global menus. Is there a way to only always show the close, minimise and maximise buttons on every application? The use case is as follows: I have a maximized application in the background, over it is a not-maximized application that has got focus. I want to close the maximized application. I move the pointer to upper left corner. The buttons do not show, since the background application does not have focus. I have to go back, click on it and then go back to the corner to close it. I do that several times a day :-( .

  • I have Ubuntu 11.10 and for no apparent reason my sidebar suddenly will not hide, how can I reverse this?

    - by cathy
    I have Ubuntu 11.10 and for no apparent reason my sidebar suddenly will not hide, I did not go into system settings or anything like that. I googled this, but everything I found had me downloading something to be able to fix it. However, as it changed without me downloading anything, I'm hoping it's possible to change it back without downloading anything. I read somewhere that I should go into "System setting", "appearance", "behaviour" and change it to "auto-hide", but I did not have a "behaviour" tab in "appearance". I would normally be able to just deal with it, but it is preventing me from being able to click the "back" button when I am in a browser. Does anyone
