• Dell Inspiron7520 and ubntu 12.04 issues

  - by user91358

  I have a DELL Inspiron 7520 in the highest configuration: 3rd Generation Intel® Core™ i7-3612QM processor (6M Cache, up to 3.1 GHz) 15.6" Full High Definition (1080p) LED Display 8GB3 Dual Channel DDR3 SDRAM at 1600MHz 1TB 5400RPM SATA HDD + 32GB mSATA SSD w/Intel Smart Response Blu-ray Disc (BD) Combo (Reads BD and Writes to DVD/CD) AMD Radeon™ HD 7730M 2GB 6.09 lbs and I have installed Ubuntu 12.04 few days ago and I'm facing some issues: 1) sometimes the whole ntb freezes and I have to hold power button for 5 secs to shut it down. I think it is something with VGA and connected external monitor. I have read somewhere that it is already a reported bug, but what I am not sure about that it is doing sporadically. Sometimes it freezes right after I log in, sometime I ran few hours and then it freezes. I am using those proprietary drivers but I wasn't been able to install those with updates. 2) the next issue is the fan is quite noisy even when the ntb is almost Idle. (max 10% CPU usage). Can you recommend me some software which could do this power management to lower the noise? I have tried CPU frequency scaling indicator, but it seems that it has not any effects. 3) and issue no. 3: when I want to log out, restart or shutdown using the menu in upper right corner the upper and left trays disappear, but programs are still running and they won't close to complete log out or shutting down the OS. When I use the CLI command, it works fine. Thanks for any help you can provide.

• How to Reset Windows 7 to its default font for the whole system?

  - by Fellknight

  This might sound a little bit silly but please bear with me. Somehow I changed my default display font, the one that Windows uses for system dialog boxes, accept/cancel buttons, pretty much everything in the system (it even goes as far as to change how my the text in my web browser appears). Now everything that it's affected looks like under the effects of the bold button in office (very black and very thick words). This is an inconvenience for example on some mail accounts who use this effect to display unread messages. Is there any way to return it to its default state, non "bold" typography for the whole system?

• Latest (5 June 14) Updates t0 10.04 Causing Multiple Problems

  - by user291780

  Apologies, the questions are very short, but the bkg isn't. I rec'd a routine notification from the update mgr a few days ago (I believe, June 5th). I took a look and there was lots of linux stuff, headers, etc., nothing obviously unusual. I'd rec'd and updated w/a more extensive pkg set, kernel and all a few weeks ago, no problem. On June 6, I pushed the upgrade button on the June 5th batch, nothing usual, needed a reboot, which I did after a full power down, it came up fine. Gedit worked, the calculator worked, started up firefox, it came up, selected the BookMarks menu, and blam, it hesitated and then greyed out, when I tried to close it, got the "process not responding" msg. Undaunted, I tried to fire up Google Chrome....nothing on the screen or process bar. I fired up the system monitor and indeed there were some "sleeping" chrome processes "running". Powered down several times, but the same problems persist. Similar but worse story when I tried to fire up one of my virtual machines, VirtualBox came up fine, but when I tried to start one of my virtual machines I got a progress popup that I'd never seen before which showed that we were making no progress past 20%. Uninstalled Oracle VirtualBox, reinstalled the latest and greatest, same result. Also, unable to logout, or shutdown once the virtual machine exhibited this behavior. Powered down manually, end of story. Never saw such a bad result after an update. I'm running Ubuntu 10.04 LTS (Lucid Lynx) as I have been for a number of years. Please don't reply with why don't you run some other version of Ubuntu, that doesn't answer the questions below. Questions: Will their be a subsequent update that fixes this, and if so, when? If not, is there a way for me to get back to where I was before this disaster?

• Is there a way to change the permissions of a series of directories on Windows 7 without getting a dialog box when it can't change the rights?

  - by leeand00

  Is there some way to change the permissions recursively on a series of directories without getting a dialog box that pops up and tells me it can't change the permissions on a particular file? I keep getting this dialogs multiple times duing the process of changing permissions: An error occurred while applying security information to: C:\pagefile.sys The process cannot access the file because it is being used another process. Eventually I get so many of them that I start clicking the mouse or pressing the space bar so many times that I accidentally click the cancel button. Also it would be great if I could keep a log of which files it can't change permissions on. Is this possible in Windows 7? Does it have to be done from the command prompt or from powershell?

• Laser range finder, what language to use? Beginner advice

  - by DrOnline

  I hope this is the right place. I am a programming beginner, and I want to make a laser range finder, and I need advice about how to proceed etc. In a few weeks I will get a lot of dirt cheap 3-5V lasers and some cheap usb webcams. I will point the laser and webcam in parallel, and somehow use trigonometry and programming to determined distance. I have seen online that others made done it this way, I have purposefully not looked at the details too much because I want to develop it on my own, and learn, but I know the general outline. I have a general idea of how to proceed. The program loads in a picture from the webcam, and I dunno how images work really, but I imagine there is a format that is basically an array of RGB values.. is this right? I will load in the red values, and find the most red one. I know the height difference between the laser and the cam. I know the center dot in the image, I know the redmost dot. I'm sure there's some way to figure out some range there. TO THE POINT: 1) Is my reasoning sound thus far, especially in terms of image analysis? I don't need complete solutions, just general points 2) What I need to figure out, is what platform to use. I have an arduino... apparently, I've read it's too weak to process images. Read that online. I know some C I know some Python I have Matlab. Which is the best option? I do not need high sampling rates, I have not decided on whether it should be automated or whether I should make a GUI with a button to press for samples. I will keep it simple and expand I think. I also do not need it to be super accurate, I'm just having fun here. Advice!

• How can i lock images to a cell in excel 2010

  - by Jamie

  Ok, so i am using microsoft excel 2010 and have a set up currently where i have 2 views expanded and deflated using the Group or +/- function. My problem is that ui have images on the workbook too. The images are over the cells which are to be "hidden" when the - button is pressed and i would like the images to disappear with them. This is not curently happening instead they are moving to the next visible cell. I have included an example below incase i wasn't clear. I wish to hide Columns M:AU and the images are in various cells suchas N5 and O5. When i colapse (hide) the column range all of the images move to "AV5" the next row along that isn't hidden. This means the workbooks is looking messy when colapsed which is the oposite of what i was trying to do. Can anyone advise on a way around this?

• 12.04 LTS Apache2 writing files from webpage at runtime has no effect - possible read/write permissions?

  - by J Green

  I'm running 12.04LTS with Apache and Mono in VirtualBox, with the goal of hosting a web app (coded in ASP.NET and C#) on my local network. The scripts on the page are able to successfully read from text files in the same directory as my site (/var/www/mysite/) but do not seem to be able to write. I'm sure the code works, because it did with my testing in Visual Web Developer on Windows. I don't get any errors, but when I click the button on the loaded webpage, the text file in question does not change. I'm fairly new to Linux in general, so I'm not too familiar with how to set permissions properly, and it may be a permissions issue. Unfortunately, I have searched all over the internet and haven't found a solution that worked, but I've tried (perhaps incorrectly) changing the owner of the files in question to www-root, changing the mode to a+rw, but sadly to no avail. I have tried everything here but it doesn't work: Whats the simplest way to edit and add files to "/var/www"? I hope someone can help me out.

• Computer won't stay powered up

  - by Android

  I have just tried to turn my PC on this morning and it won't stay powered up. It will come on as normal for about 5 seconds, not quite long enough for the monitor to wake up. Then it will power off. After about 2 seconds it will start again, it will continue like this until I pull out the plug. Plugging it in again doesn't restart the cycle although pressing the power button does. I have tried to clear the cmos but beyond that I have no ideas. It was working perfectly when I put it in hibernate last night.

• Lost access to the unity interface how to fix? (ubuntu 11.10)

  - by Tal Galili

  o.k, this is embarrassing: I have installed Compiz Config Settings Manager and tried to fix it so that the transition time between changing tabs (using alt+tab) will be short. by accident I un-pressed V from something else, and it asked me about a conflict - I pressed the "x" button to close the window and as a result I stopped seeing the unity interface. That is - I can not see any buttons of the left side. I went to the terminal (ctrl+alt+F1) and ran ccsm As a result I got the following error: $ ccsm /usr/lib/python2.7/site-packages/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display warnings.warn(str(e), _gtk.Warning) Traceback (most recent call last): File "/usr/bin/ccsm", line 93, in <module> import ccm File "/usr/lib/python2.7/site-packages/ccm/__init__.py", line 1, in <module> from ccm.Conflicts import * File "/usr/lib/python2.7/site-packages/ccm/Conflicts.py", line 26, in <module> from ccm.Constants import * File "/usr/lib/python2.7/site-packages/ccm/Constants.py", line 29, in <module> CurrentScreenNum = gtk.gdk.display_get_default().get_default_screen().get_number() AttributeError: 'NoneType' object has no attribute 'get_default_screen' What should I do next?

• Dell monitors keep blank after initial start

  - by offler

  We have Dell T1650 PCs with 2 nVidia graphic adapters / Windows 7 and 4 attached monitors. At initial start all screens are blank, the computer does not show anything. If powered off by pressing the hardware power button and then restarting all monitors show a picture. The Windows event log shows only the errors, that the machine was shut down unexpectedly. The last entry with blank screen seems to be that user specific dlls for every application are loaded. How can I find out the real problem?

• How do I make control-click in Opera open new tabs?

  - by user21952-is-a-great-name

  Update: As of version 11.50, control-click opens the new tab in background, as desired. Yay! In Opera, as opposed to all other modern browsers I know, control-click does not open a new tab. Moreover, I couldn't find any good way to configure this behavior. The best available option seems to be this. However, it's so hacky that it won't work on HTTPS sites unless you enable user javascript there, which doesn't seem like a good idea. There also seem to be other proposed solutions, but none of them seem to work. I'd like this because my laptop has no middle mouse-button, and I'm a creature of habit. Do people have any ideas (for the latest version, 10.50)? I'd like ctrl-click to open a background tab, but I can do with foreground. Thank you!

• Mouse will not click and drag

  - by C. Ross

  My mouse is currently having trouble with Click and Drag. It moves well, it clicks well (including double click); but it will not click and drag correctly. When dragging it just drops the highlighted area almost immediately after starting it. The operating system is Windows 7 x6, and the mouse is a Microsoft 5 Button laser wired model that's approximately 3 years old. The problem is relatively new, but has been happening consistently for several weeks through several reboots. Is there anything to try besides buying a new mouse?

• Enabling Office SharePoint Server Publishing Infrastructure Breaks Navigation

  - by swagers

  I'm migrating from WSS 3.0 to MOSS 2007, below are the steps I took to migrate. Backed up the content database of our WSS 3.0 site. Restored the database on our MOSS 2007 database server Create a new Web Application on our MOSS 2007 server and pointed the database to the newly restored database. Everything works correctly on the new server. I enabled Office SharePoint Server Publishing Infrastructure and navigations stops working correctly. Where it use to say Home it now says /. When I clicked on a link to any sub sites the top navigations reduces down to one button that says Error. Also any sub site navigation on the side bar reads Error. When I disable Office SharePoint Server Publishing Infrastructure everything goes back to the way it was.

• PC reboots instead of shutting down, no software problem. What could be the cause?

  - by DaVinci

  Hi, first of all: I'm not sure if superuser is the right site for my question and google didn't help. I have a pc here that prefers rebooting to shuting down. Everytime I try to shut the pc down it reboots, however it is possible to turn the pc off by pressing the power button. The problem is not windows-specific, the Ubuntu LiveCD does exactly the same that's why I said that it is no software problem. I checked wake on LAN, it is disabled and I also resetted the BIOS settings to factory default. That might not mean that it can't be a BIOS problem but I don't know what else to try here. I did not check any hardware yet but nothing exploded so far. I don't know what could have caused this behaviour as it is not my PC. The Mainboard is a ASUS P5Q-E P45.

• Why can't I open programs after watching youtube videos for a while?

  - by manjivsanotsu

  I have recently built a new PC, and it worked fine for a while (1-2 months of no problems whatsoever). However in the recent weeks I noticed that after I watched some youtube videos and closed everything, I can no longer do anything except move the mouse and expand the Startup Menu. If I click on any of the programs on the Start Menu or type a program on the Run text box, it won't open anything. I can't open taskmgr, or windows explorer, or even shut down the PC. I don't have anything else running when I'm watching videos except ZoneAlarm and Avast. The only workaround I can do when this happens is a forced shutdown (holding the power button of my PC), and restart if I wanted to do anything more. But this happens a lot - about 4-5 times a week so I'm worried it would fry up my hardware if I keep on doing this. OS: Windows 7 Other Installed Software: Open Office, Tropico 4 game, Adobe Photoshop Browser used: Google Chrome Hardware: CPU: i7 2600K RAM: 16 GB Motherboard: Asus P8Z68-V GEN3 Hard Drive: 120GB Corsair Force GT SSD Graphics: 2047MB GeForce GTX 560 Ti

• How to switch users without entering password, part II

  - by torbengb

  I've got Ubuntu 9.10 with a user account for my wife, and one for myself. "Wake-from-screensaver" should result in "choose user" without having to enter any password. I know how to do that in Windows, but I'm not good with Linux (yet). Part of this was answered in this question which helped me get past the login screen without passwords (after booting, and after choosing "switch user"), but once the screensaver kicks in and I wake it up again, the system does not present the "choose user" screen. Instead, it either turns off the screensaver and presents the desktop of the most recent user, or (if the screensaver is set to lock the screen) prompt for the user's password (which can be handily surpassed by clicking the "switch user" button and choosing the same user again). So, the login ("choose user") screen has been dealt with. How do I make the (any) screensaver return to the login screen at wake, rather than to the current user's desktop? Windows can do this, I'm sure Linux can too - but how?

• Issue with Banshee

  - by Jordan March

  I went to install Banshee using Ubuntu tweak's App button. I clicked the stable ppa, and installed. When it was done, i tried to launch it, it shows up for a split second then closes. So I though it might be having issues with Rhythmbox's associations or something. So I uninstalled Rhythmbox. But same issue. So I try to uninstall Banshee, and it won't, it fails. I thought, well maybe if I tried installing it from the terminal, adding the ppa first (sudo add-apt-repository ppa:banshee-team/ppa) updating apt-get, then sudo apt-get install banshee. But it fails. So now I can't run it, uninstall it, re install it.. or anything. I'm new to linux so I don't know how to go about rebuilding the files. But if anyone has seen this issue before, or has any idea on how to fix this, I would really appreciate the help. Thanks guys

• How do I copy files in Jolicloud from one drive to another

  - by Jason

  I'm running Jolicloud 1.2 from a USB stick. I clicked the "run but don't install option" at the start up menu and then i created an account. It says I am logged in as guest mode. How can I copy files from my original c:\ which is listed in the file manager to my usb stick. There's no button and drag and drop doesn't work is there a way to get into terminal? Is it perhaps restricted because I am a "guest"?

• Bacula configuration for clients that are turned on and off randomly

  - by Rastloser

  I'm evaluating Bacula as a centralized backup tool for a small network where users will turn machines on and off unpredictably. Some of the headless Linux boxes I need to back up are intended to be turned off by pressing the on/off-button on the case, without any way of telling the user to wait for a backup job to finish. So, we don't know when backup jobs may run (anacron might help with this, right?) and we don't know whether they'll be allowed to finish. Is Bacula a reasonable choice for such an environment?

• How to manage a lot of Action Listeners for multiple buttons

  - by Wumbo4Dayz

  I have this Tic Tac Toe game and I thought of this really cool way to draw out the grid of 9 little boxes. I was thinking of putting buttons in each of those boxes. How should I give each button (9 buttons in total) an ActionListener that draws either an X or O? Should they each have their own, or should I do some sort of code that detects turns in this? Could I even do a JButton Array and do some for loops to put 9 buttons. So many possibilities, but which one is the most proper? Code so far: import javax.swing.*; import java.awt.event.*; import java.awt.*; public class Board extends JPanel implements ActionListener{ public Board(){ Timer timer = new Timer(25,this); timer.start(); } @Override protected void paintComponent(Graphics g){ for(int y = 0; y < 3; y++){ for(int x = 0; x < 3; x++){ g.drawRect(x*64, y*64, 64, 64); } } } public void actionPerformed(ActionEvent e){ repaint(); } }

• From the Coalface - 3 - Work as hard as you can to be as lazy as you can!

  - by TATWORTH

  The saga of the Change Log A recent conversation reminded me of the need for change logs within a database, to record when various change scripts were run. Creating such the required table is simple. A typical table for this consists of: Id - identity Integer primary key ChangeFileName - NVARCHAR(128) to hold the name of the file run. DateAdded - DateTime non-null with default value of getutcdate() Purpose - NVARCHAR(128) Rerunnable - Bit non-null default 0. By good design of the table only two data values normally need to be supplied. Two stored procedures, one for inserting data and one to list in reverse sequence the log complete the database essentials. The complete implementation can be found in the CommonData solution at http://CommonData.CodePlex.Com By including a call the add Change Log stored procedure, each script can log its name and purpose for posterity. The scripts that were applied to say the UAT system and their sequence of application can be readily identified for running on the Live system. Formatting XML XML is often produced as one continous string with no embedded CR/LF. To get it into human readable form, open it in visual studio, swap to another tab and back and click the format document button. The XML will then be nicely formatted!
