• Switching windows behavior in Ubuntu

  - by Leonid

  Ubuntu supports a shortcut to switch windows Ctrl+Tab, but it allows you to move through apps in one direction only. Direction depends on whether initially Ctrl+Tab or Ctrl+Shift+Tab was pressed. Ctrl+Tab will move forwards, but pressing Shift while moving forward doesn't change the direction, it still goes forwards unlike Windows default behaviour. Ctrl+Shift+Tab will move backwards, but if Shift is released while moving backwards the menu will disappear. Is there a way to configure Ubuntu so that you could go backwards and forwards without running the menu twice?

• Dual monitor, with a low resolution projector

  - by user900978

  I need to show a presentaion to a conference tomorrow. Today I tryed my Ubuntu 10.04 with the projector. My notebook has a resolution of 1440x960, the projector seems to have a really lower resolution. However, thanks to nvidia-settings I configured my video card (a nvidia 9800), it works with other display, but not with the projector. I found the projector, configured as Twin-view, resolution Auto and pressed on Apply, then "Save to x Configuration". On projector is visualized just a quarter of my notebook display. I tryed also to reduce my resolution and to change the resolution of projector, but I obtained no better results. How can I Solve it? On windows all goes well, but I need Ubuntu for personal reasons. Thanks in advance

• Change players state and controls in-game

  - by Samurai Fox

  I'm using Unity 3D Let's say the player is an ice cube. You control it like a normal player. On press of a button, ice transforms (with animation) into water. You control it completely different than the ice cube. Another great example would be: Player is human being and has normal FPS controls. On press of a button human transforms into birds and now has completely different controls. Now, my question is, what would be easier and better: make one object with animation transition and to stay in that state of anim. until button is pressed again make two object: ice and water. Ice has an animation of turning into water. So replace ice (with animation) with water object And if anyone knows this one too: how to switch between 2 different types of player controls.

• How to modify Dreamweaver's SpryMenuBar.js to send a msgbox on what menu was clicked?

  - by Mike

  I have a simple HTML webpage made in Dreamweaver with a SpryMenuBar. When I click on a menu item, I want to send a pop up message box that says which menu item was clicked. (This is not really my objective but once I can learn to hook into the spry java script with a mouse click listener I can try to do what I am really after.) The problem is for some reason I can't seem to get started with this seemingly simple task. Does anybody know how to revise the SpryMenuBar.js to make a msgbox showing the item that was clicked? For example if I click a menu that say's 'Contact us', I wan't to throw a message box that says "You pressed, Contact us". Note: My final objective is to actually call another function that changes text in the center of my page, depending on what menu item was clicked.

• How to fix the copy/paste-pattern?

  - by Lenny222

  Where i work, people (consultants) feel pressed to release features as fast as possible. So instead of spending too much time on thinking about how to do things the right way or because they don't want to break anything, code gets copied from different modules and modified. It's not easy to prevent this, since the code base is open to the whole company. Lots of people work on this. Now that the mess is there already, what is the best way to remove those redundancies without breaking too much?

• Load balancing on Ubuntu Server

  - by SabreWolfy

  I have Ubuntu 10.04.4 server (32-bit) installed on a headless quad-core machine with 2GB RAM. I'm running a command-line analysis which is analyzing a large amount of data, but which does not require a large amount of RAM. The tool does not provide any multi-threading, so the CPU load is sitting at 1.00 (or sometimes just a little over). I ran top and pressed 1 to see the load on each of the cores and noticed that "Cpu1" is always running at 100%. I thought that the load would be distributed between the cores, rather than loading one core all the time. I'm sure I've seen this load-balancing behaviour before in Ubuntu or Debian Desktop versions. Why would the Server edition work differently? The analysis will likely take several hours to run, so loading one core at 100% for many hours while the other 3 remain idle is surely not the best approach?

• Google search does not show sub-pages from my website

  - by user5679

  My website appears in Google search, but only the first page. Of course I have sub-pages linked from the first page, but the sub-pages do not show in Google search. Not in Yahoo, not in Bing. What should I do? It has been three years that sub-pages do not show. (I tried searching site:mydomain.com and pressed 'repeat the search with the omitted results included' link) What would you suspect the reason? My website addresses were like xxx.php?yy=zzz etc, etc, so I changed it to /yy/zzz using mod_rewrite. I thought it might be (X)HTML standard violations, so now I changed it. I hope Google will soon have my entire website, but I am a little bit pessimistic. Do you have any thought?

• Is it possible to get dragging working on a Macbook multi-touch touch pad?

  - by lhahne

  I have a Macbook 5,1. That is to say that it is the only 13 inch aluminium Macbook as the later revisions were renamed Macbook Pro. Two-finger scrolling seems to work fine but dragging doesn't work. In OsX this works so that you point an object, click and keep your finger pressed on the touch pad while slide another finger to move the cursor. This causes weird and undefined behavior in Ubuntu as it seems the driver doesn't recognize this as dragging. Any ideas?

• How can I set up a keyboard shortcut so that Ctrl+Backspace = Del?

  - by Palantir

  As an old mac user, I am used to hitting Ctrl+Backspace, and the effect is the same as if I pressed Del. I have recently purchased an Asus N53SV laptop which has replaced my MacBook, but unfortunately this laptop has a very annoying keyboard layout, where the Del key is in a non standard position, and moreover it is TINY. Is it possible to get the Ctrl+Backspace combination to issue a Del and how would I do this? Using Kubuntu, but I believe this is to be done at X level, not at desktop, am I right? Thanks!

  I was trying to replace Zorin OS 8 with ubuntu 14.04 (32 bits). What I have tried: I took an empty pen drive and downloaded Ubuntu 14.04 iso file on to this pen drive.

I know I am "fundamentally" wrong in the manner how I am executing this installation process. If you could please provide me a stepwise instruction.

• Xfce Power Manager on Xubuntu 13.10 doesn't work

  - by kirokko

  The problem is that its actually works, but something works with Xfce Power Manager at the same time. For example, I set that if I pressed Suspend button (on my Lenovo B560 its Fn+F2 hotkey) then system ask me what to do. But when Log out window appears, system goes to suspend. Another example is closing the lid. I set it to lock the screen via Xfce Power Manager, but system still goes to suspend. I thought that it might be laptop-mode-tools, but it's not installed. Before 13.10 I had 13.04 and everything were fine.

• Alt/Shift key not released after switching keyboard layout

  - by szx

  Sometimes when I switch layout using either Alt+Shift or Ctrl+Shift the Alt key is not recognized as being released thus if I press e.g. F a File menu opens up. Last time that happend I lost all data I filled into a text form on a webpage because I pressed the Home key while typing and Firefox suddenly went to my home page! Moreoever, it still remains unreleased after hundreds of keypresses like if I'm holding it! Same goes for the Shift key. I would rather file a bug at Launchpad if I could but I have no clue what fucking package name should I type in the ubuntu-bug command! Have anyone else had this issue? Can you suggest a solution or maybe another place to report this bug?

• Ubuntu 13.10 upgrade error. Dropping to low graphics mode

  - by aero31aero

  I was updating from the terminal and it was complete. It asked me if I would like to reboot now. I accidentally pressed 't' instead of 'y' and then it just asked me to reboot manually. Then I rebooted using sudo shutdown now -r And on reboot, the system flashed the "low graphics mode" error screen and its stuck there. I have 13.10 live-USB with me. Is there any way I can get my system to boot normally? I'm not willing to do a fresh install as I had installed several other packages. Another question: is there any diff if I drop into terminal using Alt+Ctrl+F1 or if I use chroot from a live session?

• Flickering/Flashing screen problem related to keyboard

  - by LeandroCR

  This will seems quite bizarre but that's a huge problem for me, I'm facing it for a long time since Ubuntu 12.04. My Ubuntu/Linux Mint/Debian (Unity/Gnome) always starts flickering after using the computer for a while, I always thought this had something to do with the video board. I have an Vostro 3550 (Radeon 6xxx/Intel Onboard). First I realized that when I was navigating trough an website, when i selected with the mouse a combo, the combo closed it self automatically then the screen starts flickering. The i realized when i was trying to make the login in the terminal (crtl + alt + f1) a strange character appears, like: ^@ repeatedly. When i keep CRTL pressed the system never flickers! I have absolutely no problem using Windows. What can i do? There is no such thing as Keyboard driver on Dell Support. I would love to use Ubuntu only, but this is very annoying. Problem happens on Ubuntu 12.04, .10 and 13.04 Linux Mint 15 (Cinnamon) Debian Live with Gnome

• Why is my Workspace switcher view skewed

  - by Lee

  I have been using Workspace switcher in Ubuntu just fine but recently have encountered this problem. The windows in the switcher don't fill the screen. I must have pressed some combination of buttons somehow but can't find any information anywhere in regards to resizing them. As you can see in the screen shot it looks like a perspective view or something. http://i1115.photobucket.com/albums/k553/lmt337/Screenshotfrom2012-07-04103519.png I should also add I have a dual monitor setup and nvidia graphics. The switcher still works but the fact the screens dont fit my actual screens is driving me nuts. Thanks in advance for any help.

• Major problem with Nvidia drivers

  - by user38580

  Since I decided to use Ubuntu -yesterday- I've been struggling with the drivers. It isn't recognizing my optical disc drive nor my video card, a Nvidia 8500gt. For the matter, here's how I "successfully" installed the .run driver downloaded from Nvidia's website: The terminal wouldn't let me start the installation because the X server had to be shutdown, so I pressed Ctrl+Alt+F1 Then, I used: sudo service lightdm stop cd /(directory where the nvidiaupdate.run was) chmod +x nvidiaupdate.run sudo ./nvidiaupdate.run The installation began and got completed, but unfortunately it crashed Ubuntu's UI, invalidating the OS for me. All that would appear was a DOS-like screen with reports. I'm new to Linux, so I really would appreciate any help given. For now, I'm sticking to the additional drivers, but even with it Ubuntu doesn't show my video card in the informations of the system. Forgive my bad English.

• New Project Starting. Got Gas?

  - by merrillaldrich

  “Storage is just like gasoline,” said a fellow DBA at the office the other day. This DBA, Mike is his name, is one of the smartest people I know, so I pressed him, in my subtle and erudite way, to elaborate. “Um, whut?” I said. “Yeah. Now that everything is shared – VMs or consolidated SQL Servers and shared storage – if you want to do a big project, like, say, drive to Vegas, you better fill the car with gas. Drive back and forth to work every day? Gas. Same for storage.” This was a light-bulb-above-my-head...(read more)

• mouse and mousepad not working properly

  - by snake

  Ubuntu 12.04 LTS Samsung Q35 The mouse pad has stopped working, only the buttons work. The external mouse is also behaving very oddly, the mouse pointer works, but the button is not working properly, it has to be pressed many times or held down to select anything, and when anything that I select behaves as though the mouse is being clicked all the screen, settings will keep changing, the page will scroll, sliders will move up and down, tabs will toggle etc, so everything is unusable with the mouse, cannot even use the browser as it keeps scrolling the page up and down. I have tested the mouse on another computer, and it works fine. Please bear in mind that I am also a complete Linux novice, I installed Ubuntu on an old laptop for my kids, that is the limit of my experience.

• Webmatrix fails to connect PHP website to MySQL

  - by Roni

  I downloaded the latest versions of Webmatrix and MySQL. I downloaded a PHP-MySQL Connector: http://dev.mysql.com/downloads/connector/php-mysqlnd/ In the "Databases" Workspace I pressed "New Connection" button and choose "MySQL Connection" In the Dialog box I filled-in all connection details -- It looks like the database was added. But then when I double-click on the database, I get a short error message saying it cannot connect. I tried everything, searched the web... I'm sure it's a very simple question, so please whoever can help I'll be grateful. I think best solution for me would be if someone could please just give me a link to download of: Webmatrix,MySQL,Connector; and instructions on how to install and then how to connect. This would be the safest way to help me.

• 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

• Computer won't wake from hibernate

  - by Icoo

  So I have a pretty dumb problem...I accidentaly pressed Hibernate while trying to Restart...since then my computer wont boot into Ubuntu anymore (through normal mode or single user mode - rescue mode that is)...all I get is: mount: mounting /dev on /root/dev failed: No such file or directory mount: mounting /sys/ on root/sys failed: No such file or directory mount: mounting /proc on /root/proc failed: No such file or dirctory Target filesystem doesn't have requested /sbin/init. No init found. Try passing init= boot arg. BusyBox v1.15.3 (Ubuntu 1:1.15.3-1ubuntu5) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) Obviously I tried to fire up the Live CD and run fsck (or e2fsck) from there (or just try to do a Check of /dev/sdb1 my partition via gparted - which is basically the same thing). But it doesn't allow me...both gparted and fsck say that the device is busy (I can't even mount it in the LiveCD to rescue data)...umount /dev/sdb1 says its not mounted...any ideas?

• Acceleration Based Player Movement

  - by Mike Sawayda

  Ok, so I am making a first person shooter game and I am currently working on movement that looks and feels good. I want to incorporate acceleration based movement for the player so that he has to accelerate to max speed and decelerate to minimum speed. Acceleration will happen when you have the key pressed and deceleration will happen when you let go of that key. The problem is that there are some instances where you switch from moving forward to moving backward where no deceleration is needed because you could potentially be moving at double speed in the reverse if you did. Does anyone have a good implementation of how to accomplish acceleration based movement that works well?
