• Kernel panic when booting from USB

  - by maaartinus

  I downloaded ubuntu-11.04-desktop-amd64.iso and used Universal-USB-Installer-1.8.6.3.exe to format my USB stick und put the ISO on it. When I tried to install from it, I've got a kernel panic just like here, except for the version number (mine was 2.6.38-8-generic #42-ubuntu). My ISO image seems to work, as I installed it into a VMWare player without problems. Booting Linux from USB works surely too, as I did it some time ago with an older Ubuntu version. I can imagine things to try out, e.g., write the image again, try another version, pray, look for patches, etc. However, I'm looking for a time-efficient solution, something what most probably works. An advice of the sort "wait two weeks until it's surely fixed, then download again" is acceptable, I'm determined to switch to Linux, but it can wait a bit.

• Linux Programmer moving to Windows

  - by cytinus

  I am a fairly proficient Linux programmer. I have been coding in Linux for 4 years, for both personal reasons and for profit. During those 4 years I have not even owned a computer running the Windows operating system. I am looking to expand my horizons into Windows programming, but am finding myself overwhelmed with the lack of what I perceive to be standardization. I feel as though different compilers follow different conventions, and all of the worthwhile IDEs cost money. Whats worse is that so many of the Tutorials are just terrible. If anyone else has taken the switch from Linux to Windows programming, what was the most helpful. What are the most straightforward IDEs and tutorials for using the API. I am looking to do mainly C and C++ development, along with some x86. I have found MASM primarily suits my needs for the latter.

• Is there an easy way to (temporarily) disable the display timeout?

  - by Izzy

  In KDE 3.5 there was the powermanager plugin for the kicker panel, where one could easily switch between different profiles. So normally, I want the display to go to sleep after, say, 10 minutes of user inactivity. But when I watch a video, this should not happen. I know I could go via the KDE launcher, settings, powermanager, and change the setting. But this is too complicated for daily use. I also know there are those activities. But I don't want to change background etc., just the display timeout. Furthermore, when I tried this, many of the open apps simply crashed and got restarted. I simply don't like this approach. Preferably, it would be something to plug-in to the panel, which opens a menu to select the profile -- as it was with KDE 3.5. Is there a similar solution I missed?

• HTG Explains: What is DNS?

  - by Chris Hoffman

  Did you know you could be connected to facebook.com – and see facebook.com in your web browser’s address bar – while not actually being connected to Facebook’s real website? To understand why, you’ll need to know a bit about DNS. DNS underpins the world wide web we use every day. It works transparently in the background, converting human-readable website names into computer-readable numerical IP addresses.

• What is a light-weight "slideshow" script that could integrate w/ CMS?

  - by aslum

  I'm looking to reduce the footprint of my Strict html 4.01 front page. One possible way is to combine much of the "upcoming events" into a single small box, and have them automagically switch which one is displayed every few seconds. I'm sure there are a bunch of this kind of thing written already, and surely an open source one exists, but I haven't had much luck find one. I'd prefer javascript to jQuery as installing jQuery might not be an option, but if the best-fit script requires jQuery I'd certainly be willing to investigate that route. If it can display content from Wordpress that would be ideal.

• HP dv2700 series, Wifi not working in Ubuntu 12.10, Wifi Button always disabled

  - by Chicoscience

  I have a HP dv2745se laptop. I always had Ubuntu with the Native Windows Vista and Wifi worked fine. Suddenly my Ubuntu wouldn't load anymore, I tried fixing it for a week and eventually I formatted its partition and just installed Ubuntu 12.10 This laptop has a Wifi switch that works fine in Vista disabling / enabling the wireless connection. HP Wireless Assistant in Windows say Wireless is on. However, whenever I log in Ubuntu the Wifi button is always orange (disabled) and Wireless never works. I had this problem once when I had Ubuntu 12.04 and I fixed it by verifying in Windows that the Wireless Assistant showed the Wireless LAN in "On" mode. However, the same does not work now. I've seen some possible solutions that involve updating the firmware with apt-get. There comes my 2nd problem, my network adapter card is not working and thus I have no internet at all. Any suggestions? Thanks!

• What is the feature that imports URL information into facebook and google+?

  - by Michael

  What I am trying to do. I want to be able to import heading, short description and an image into my website, just using a link. I am using Joomla but can switch to any CMS, or try to build an extension myself. The problem is I dont know where to look for example code, or what to look for. To me it doesnt seem like too difficult a process. Also, the code must be out there, with a little tweaking I can probably use someone elses, but I dont even know what to search for.

• wrong SEO result for staging website

  - by OCD

  Hi, We have a domain with URL, lets say: http://www.xxxxstaging.com/abc.php?id=10 which is having a pretty good ranking for some keywords in google. However, this is our staging website and due to some historical reason, it was exposed to public. Now we have a production domain (the one we want to be publicly available), say: http://www.xxxxproduction.com/abc.php?id=10 which have exactly the same html output as xxxxstaging.com our question is, for the exactly same keyword search, it never appear in any page of google. Is it possible for us to "switch" the ranking in google, either tell the robot that they are indeed the same website, or tell google to change it for us? Thank you.

• Gnome 3 freezes when switching workspaces

  - by Bill Cheatham

  I have found an odd problem with Gnome 3 on Ubuntu recently. Under certain circumstances, when switching between two workspaces the whole desktop and user interface will 'freeze' for anything up to 2 minutes; during this time I cannot click anything or interact using the keyboard. Often, the screen will show a 'half-completed' animation of the workspace swapper. This is on Ubuntu 12.04.1 running on a 2-year old Macbook Pro, and it only seems to occur when using an external monitor. This does not seem to be a processor or memory issue, and does not occur every time I switch workspaces. Is this a known problem? What can I do in the short or long term to fix it?

• Can't install ATI proprietary drivers in 12.10. Unity is Missing

  - by EApubs

  I have a laptop with ATI Radeon 6770M HD Hybrid graphics card. In Ubuntu 12.04, I installed the fglrx driver through "additional drivers" and it worked. (I can even switch GPUs). But in the new Ubuntu 12.10, after installing, Unity won't load. Only the mouse and the wallpaper. If I initialize the settings sudo aticonfig --initial then after rebooting it gives a warning saying I'm in low graphics mode! How to fix this? PS : Earlier i used software source to install the drivers. But when using the terminal, I got this warning : update-alternatives: warning: forcing reinstallation of alternative /usr/lib/fglrx/ld.so.conf because link group x86_64-linux-gnu_gl_conf is broken Update : Filed a bug report in launchpad : https://bugs.launchpad.net/fglrx/+bug/1068661

• Bomb timer adventure game win32 c++ [on hold]

  - by user3491746

  I'm working on an adventure game in win32 and opengl for my 2nd year university project for class. I am pretty much finished my game but I'm stuck on the concept of how to program a timer which outputs hh : mm : ss -- but which countdown, not up. I've made a clock which counts up using vector matrices and the segxseg matrix algorithm but I cannot figure out how to make a clock (it can be simple even text using wsprintf) that counts down in that format. Can anyone possible give me an example or some literature that I can read on how to do this? Please dont suggest for me to use another environment, I've already been working here for 2 months on this game, and I'm pretty much done so i'm at no point to switch over. Can anyone show me how I can take a shot at this component of my project? Thanks a bunch! Anything that I can get is appreciated.

• LWJGL in Visual Studio (possible)?

  - by Suds

  I switched from XNA and C# to LWJGL and Java about 14 months ago. Inherently, this called for a switch in IDE. I started using eclipse because I have also done some basic Android development in the past. I soon switched to Netbeans - Eclipse is just too primitive. After using netbeans for about six months, I've started looking over the fence at Visual Studio 11, toying with Metro apps for windows 8. Now I want to know, is there any known way to use Visual Studio for LWJGL?

• How To Delete Your Skype Call and Chat History

  - by Gopinath

  Just like every other modern application, Skype also records all the communications we exchange using it. It records instant messages, calls, file transfers, SMS, etc. and makes it easy to view using the Conversation tab. If you ever feel like getting rid of these history information, then you need to delete them. Skype provides a single click option to clear all the history from you account, but the feature is buried deep under options menu.Really deep!. To clear history follow the menu Tools –> Options, switch to Privacy Settings tab available on the left side, click on Show advanced options button and finally hit the button Clear history. Ah! You are almost done. Just confirm a popup it displays on screen and your history is vanished from your account. Join us on Facebook to read all our stories right inside your Facebook news feed.

• Evoluent Vertical Mouse - Re-mapping Buttons?

  - by Paul

  I have the Evoluent Vertical Mouse at work and at home. One is wired, the other wireless. Ubuntu maps their buttons differently and it makes me crazy when I switch locations. I use 12.10, but same has applied to every Ubuntu version since 9.10. The wired mouse is as desired: top finger button is left-click, scroll wheel is middle click and scroll, middle finger button is a right-click. On the wireless version, bottom finger button is mapped to right-click and the middle finger button is center-click. I tried tinkering with these instructions, but wound up unable to boot to GUI... had to delete the .conf file to recover: http://denishaine.wordpress.com/2011/12/01/evoluent-mouse-with-ubuntu-11-04-and-11-10/ Help?

• How to add a command permanently to grub2

  - by tomodachi

  I have a fairly special setup, using Linux on a MacBook Laptop. to switch off my secondary graphics card in it I'm required to add these lines to my grub outb 0x728 1 outb 0x710 2 outb 0x740 2 outb 0x750 0 I do this by pressing 'e' for my selected grub menu option and adding the lines one by one . then finally booting . But as we know it's not permanent. I cant really figure out where i need to add it for grub to always append it to my Linux boot options. It's doesn't seem to belong in /etc/default/grub since here i can add stuff to the kernel boot line Honestly i'm afraid to fiddle to much with grub on my computer since getting it to triple boot Linux/Mac/Windows was a very delicate and timely matter. Does anyone have any idea of where to add it?

• Touchpad stopped working out of the blue

  - by KI4JGT

  So, I'm watching "The Walking Dead" and all of the sudden I lose control of my mouse through the touchpad. At first it was just for my user. I could reboot my system and switch to another user and use it just fine. I cannot explain the steps I took (I'm using the keyboard to manuver firefox right now) but it was something along the lines of: sudo modprobe -r psmouse && sudo modprobe psmouse proto=imps After this command, I regained control of my mouse but the computer didn't recognize it as a touchpad. I thought if I rebooted again, it may do the trick. So after I rebooted, the mouse went completely kaput. I cannot get the mouse to work at all now even though I've tried the command several times. I've tried different users and it's still the same.

• All tweak settings not saving?

  - by mawburn

  I am running Ubuntu GNOME 14.04. After the last 2 updates, all settings in the Tweak menu are no saving. It will also not switch to the Gnome Dark theme at all. This includes all Startup Application changes as well as any changes to Extension settings. I'm not sure if I need to include any sort of log records or anything like that, so if you need any more information please ask. I've noticed the default fonts seem to be different. I don't remember that being part of the theme settings. It's almost like I'm running in Safe Mode.

  I just installed an ubuntu on my pc(Dell Inspiration I560SR-358, with CPU E5700 3GHz, 4G memory, and NVIDIA GeForce G310). The pc becomes noisy before that it's quiet with a windows 7 on it.

I think that is the reason. //re-edit Everything gets ok after I restart the computer.But the fan is still running which makes it noisy, if i switch to windows 7, it becomes quiet again.
