• I cannot change the screen brightness

  - by user1793249

  here's my problem: Ever since I installed Ubuntu 12.10 on my computer I haven't been able to change the screen brightness, it was always set to the maximum. I did take a look at this post: Decrease Backlight Below Minimum And it helped me resolved the issue with the unbearable brightness, however one problem persists: I cannot change it through "Brightness & Lock" or the function buttons (F2 and F3), when I press the buttons, the animation shows up but nothing happens. I tried the following: http://www.refreshit.info/2012/08/solved-brightness-increase-and-decrease.html It did nothing... If it helps: I have an HP-dv6 6185la, it has an ATI Radeon 6770M HD card and an Intel HD Integrated Graphics Card It only detects the "Intel® Sandybridge Mobile" Thanks in advance.

• How to make Bumblebee work with HP Pavilion DV6T-7000 Quad Edition with Intel HD 4000 and Nvidia GeForce GT 650M 2GB?

  - by user69469

  I just recently bought a HP DV6T-7000 Quad Edition. It has an Intel HD 4000 and a Nvidia GeForce GT 650M 2GB with Optimus. I read that I could use bumblebee to make optimus work, so I installed it. I also installed bumblebee-nvidia and nvidia-current from the ubuntu-x-swat/x-updates ppa. I rebooted, but when I tried to run anything with optirun, the computer would wait ten seconds or so, then do a hard shutdown. I got no log messages from bumblebee, Xorg, or optirun, either. I have purged and reinstalled bumblebee, bumblebee-nvidia, and nvidia-current. I have also set the turned off power management in the bumblebee.conf file to no avail. I am out of ideas about this, and I need both options. Any ideas would be much appreciated.

• How to select which account is logged in at system startup, or none?

  - by hippietrail

  I'm helping out some friends with a tiny hospitality business where one desktop computer has some files used by the business in one account "hotel" but it's mostly used by guests for browsing the web in another account "guest". It's low security, we're not worried about hacking or anything. But we don't want people accidentally moving our files or anything either. But the system always boots into the "hotel" account without asking for a password, even though the account has a password. We want it to boot into the "guest" account. I know a bit about computers generally and Linux but not much about Ubuntu and the ever-changing graphical environment the Linuxes are going through these days. We've looked through the obvious settings/preferences/options and I've done some Googling. I know this should be obvious easy stuff but I can't find it. (We're running 10.04 LTS on a generic aging Intel box.)

• Best video recording & mixing software for Ubuntu

  - by ???? No

  I'm searching for a quality software for recording video streams and mixing 3 cameras' streams and photos. I need it also for online streaming on a website. It could be a commercial software, doesn't have to be open source or free. I just don't have a clue if there is something like this. Thanks in advance. P.S. It's for Ubuntu 12.04 P.S.S. Maybe my definition is not correct or full, so I have to add - I need the program for live broadcast and recording on the computer at the same time.

• reading parameters and files on browser, looking how to execute on server

  - by jbcolmenares

  I have a site done in Rails, which uses javascript to load files and generate forms for the user to input certain information. Those files and parameters are then to be used in a fortran code on the server. When the UI was on the server (using Qt), I would create a parameters file and execute the fortran code using threads so I wouldn't block the computer. Now that is web-based, I need to make the server and browser talk. What's the procedure for that? where should I start looking? I'm already using rails + javascript. I need that extra tool to do the talking, and no idea where to start.

• How to display time in the top panel?

  - by Mörre

  I thought I already had the time up there in the top bar, and it may have been so in previous Ubuntu versions (don't remember, my Ubuntu laptop is just one of three computers I use). Only that I just noticed - me being someone who never wears a watch, has the cellphone turned off 95% of the time and relying on the computer to tell the time - that there is no time being displayed anywhere, and I had expected it in the top bar on the Unity desktop. I searched around but found no obvious solution, but I'm sure someone immediately knows how I can get my time (back?) into the top bar?

• Setting Default Ubuntu eth port

  - by No1_Melman

  Background: I have a desktop computer running Ubuntu 12.04. I have installed DRBL to handle DHCP server and Clonezilla Server. I have a network card in my desktop with 2 ports in it. These 2 ports are bonded together and are used by DRBL. There is a 3rd port integrated in the motherboard. I want to use this 3rd port for internet. DRBL knows that this is set for internet. Ubuntu Network-Manager has stopped recognising the connections (device not managed). It use to say that eth1 was default (first port in the network card) I want eth0 to be default as that is the Internet port. Question: How do I make network-manager see eth0 as the defualt port?

• How do I access an external drive mounted on a machine on my own network?

  - by avilella

  I've got one desktop computer Ubuntu 11.04 with an external USB drive mounted on it on the home WRT54L Linux network (192.168.0.2), and when I arrive at home with my laptop, I want to be able to mount the external USB drive from my Ubuntu 11.04 laptop (192.168.0.3) to the desktop, without having to unplug it from the desktop, that is accessing it. Is it possible to send a remote mount command to the desktop usb drive from my laptop? Ideally something that creates a local mountpoint I can just call locally from the programs installed in my laptop, like: username@laptop ~ ./myprograminlaptop /my/file/which/is/actually/on/the/desktop/file.txt

• Upgraded to Ubuntu 12.04--keyboard & mouse no longer work--system down!

  - by Mackey Morgan

  I upgraded from Ubuntu 11 to 12.04, today, and everything seemed to go smoothly up to, and including the reboot. However, I now find that my mouse and keyboard no longer function, so I cannot login or otherwise use my computer. I have read other posts on this topic, but most of the answers seem to require the use of a keyboard to implement the solution--and I can't use my keyboard! I downloaded a 12.04 LiveCD and tried booting from it, but I have the same issue with that--no keyboard! My systems is a Lenovo with an AMD64 dual processor, and my keyboard and mouse are USB attached and shared with two other Windows PCs via a KVM switch (so I no the keyboard and mouse work!). I would appreciate some hints about how to make this PC usable, again. Thanks!

• Keyboard activation bug

  - by Skydreamer

  I'm using Ubuntu's last version and there's still a little problem on my installation (already on previous versions). When I start the computer and reach the login screen, I have to wait about a minute to be able to begin to use my keyboard. That's not a real problem but that's kind of annoying. I've tried some things such as a lsusb via ssh and it worked and activated the keyboard without waiting. So I've tried to put it in the crontab (with @reboot) but it doesn't really work. Has someone got an idea how to solve this bug ? Thank you in advance.

• Strange sound distortion using headphones

  - by Luca

  When I use headphones, the sound comes out distorted. Voices sound as if they were far away, while instruments that should be in the background sound enhanced. When I play songs with the laptop's integrated speakers everything is alright, and the headphones work normally when plugged into another computer. I tried reloading ALSA and reinstalling some of the related packages, but nothing worked. I'm using Xubuntu 12.04 32-bit. Thanks to anyone who will suggest me how to solve this problem.

• Fujitsu B6220 laptop, sometimes my desktop freezes upon resume from standby

  - by user89756

  I installed Ubuntu 11.10 on my Fujitsu Lifebook B6220 laptop just before 12.04 was released. I can not remember if I had this issue with Ubuntu 11.10 as I updated the install to 12.04 about a week after 12.04 came out. My problem is that sometimes upon resume from standby my desktop is frozen. The keyboard, touch pad, and touchscreen work, but there is no response from the desktop. I can ctrl-alt-f2 and log in and then from there I just reboot the computer. This happens about 50% of the time when I resume from standby but I have not noticed a distinct pattern. I have thought about reinstalling 12.04, since I upgraded 11.10 to 12.04 instead of a fresh install. But I have customized my laptop a lot and I would prefer to avoid reinstalling it, I'm not even sure if that would fix it. Anyone have a idea what might be the problem? If I should submit this as a bug, could someone point me in the right direction please? Thanks, Matt

• Serverless Web Application

  - by Andrea Di Persio

  In my company we work on a software that produce reports in html format. My bosses love the fact that static html pages can be moved across computer simply by moving/copying a folder and no web server is involved, so the customer only need a browser. The problem is that they asking me to implement a lot of feature which is very hard to implement properly and in a clean way without an application server. Frames cross domain problem, the impossibility to work with GET and POST data, no URLs routing...is very hard to work with this limitations. Anyone had similiar experience and wants to share their tricks/suggestion ? Do I need to tell my boss 'there is no future without a web server'? Regards.

• How to Automatically run two commands after login?

  - by Covi

  I have these two commands that I need to manually run every time after login: autossh -M 2000 -N -f -q -D 127.0.0.1:7070 [email protected] and sudo mkdir /media/C sudo mount /dev/sda2 /media/C I'd like to make them automatically run every time I boot and login to my computer. I'm currently using 10.04LTS. BTW, I only vaguely know what init.d or runlevel mean. But I still prefer to know a command-line based way to achieve this, not a fancy GUI way. Also, the autossh will only succeed after Ubuntu automatically detect and connect to my network, so should we let it retry infinitely until successfully executed? Thank you!

• How to debug Android App Eclipse?

  - by user2534694

  Ok. So while this isnt a programming question. I wanted to know how do people debug apps? How do you view log cat, and where these exceptions are thrown etc? And do I need to run the app on the emulator to see all the stuff, or is there a way to view this after running the app on my phone(while not being connected to the computer) Links to plugins and tips would be really helpful, as im gonna start work on my next game, and while the first one works fine, had a lot of problems while debugging.

• Why is it good to split a program into multiple classes?

  - by user1276078

  I'm still a student in high school (entering 10th grade), and I have yet to take an actual computer course in school. Everything I've done so far is through books. Those books have taught me concepts such as inheritance, but how does splitting a program into multiple classes help? The books never told me. I'm asking this mainly because of a recent project. It's an arcade video game, sort of like a flash game as some people have said (although I have no idea what a flash game is). The thing is, it's only one class. It works perfectly fine (a little occasional lag however) with just one class. So, I'm just asking how splitting it into multiple classes would help it. This project was in JAVA and I am the only person working on it, for the record.

• category title and affect on SEO and ranking [closed]

  - by Mark

  We are working on a jobs and skills website (similiar to Skill Pages) and are deciding on the names of categories. Rather than having loads of categories and sub-categories like, for example, Builder, Electrician, Carpenter etc, we would like to have more general and easier on the eye category names. So for example we have House, Computer, Education, Art etc. So a builder would be in category House and a few others. Will this style negatively effect our SEO and ranking? And if so, should we abandon and go back to traditional categories and sub-categories?

• Ubuntu 12.04 won't boot at all for the first time

  - by user76280

  Using http://www.ubuntu.com/download/desktop/windows-installer So I tried installing Ubuntu for the first time today, and it installed all well, but then it froze at the 'Preparing to run Ubuntu for the first time...' screen. I then proceeded to restart my computer and load Ubuntu from the OS selection screen. My screen completely froze and the picture didn't even come up fully as if my video driver was not installed correctly. Are there any fixes to this problem? Would greatly appreciate it.

• Kernel Panic while Installing Ubuntu 12.10 from USB Drive

  - by user100889

  Good evening, I recently looked into installing Ubuntu alongside my Windows. I was able to mount the iso on a USB drive using Universal USB Installer. I verified it with the MD5sum utility and the hash is correct. When installing, I can get to the screen where I choose the boot order, select the USB drive, and then I get to a screen where Ubuntu seems to be 'loading' (purple background with Ubuntu logo and name in the middle). Then, all of a sudden, I get a "Kernel Panic - Not syncing: fatal exception in interrupt" error message. My specs : Intel Core 2 Duo CPU T5850 @ 2.16 GHz / 4 GB of ram / Packard Bell computer from 2007. / Windows 7 Ultimate x64 installed. What should I do now ? Thanks for your help.

• AMD Catalyst Beta Open Source Drivers

  - by FourZer0

  I'm a gamer with a pretty low-end computer, so I always update to the beta drivers to squeeze out every bit of performance I can get. I currently have 13.3 installed, but I want to install the 14.6 beta. I want to use the open source version, instead of downloading from AMD's website. How can I do that in the terminal? And please explain what the commands mean so I can do it on my own in the future. Thanks in advance!
