• Mic not working when vga connector removed

  - by yygyt

  I have a computer that should run continuously without any connection to a monitor. For developmental purposes I have been keeping the vga connection with the monitor and experienced no problem until now. When I start the machine removing the vga connection beforehand, external microphone does not work. At first I didn't know anywhere to look and see the problem, but after a google search I saw that there is a command as alsamixer I ssh the machine end type alsamixer when it is connected to the monitor, here is the result If I remove monitor connection and reboot again, and then type alsamixer, I see the error, $ alsamixer cannot open mixer: No such file or directory I suspect that this error is related to X somehow. I really don't know anything about what goes beyond. This machine needs to work without any connection to a monitor. I would deeply appreciate any suggestions.

• 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.

• cannot install ubuntu 12.04 using wubi

  - by vicky

  I recently installed windows 7 on my pc and I have been unsuccessfully trying to install ubuntu 12.04 on it. I used to have dual boot system before both with windows and linux. I changed my hard drive from ide to ahci (default option) burned the ubuntu cd properly (not the .iso file) using the ubuntu 12.04 distribution I downloaded from the official site, set boot priority to cd/dvd but.. Nothing. It tries to boot from the cd, doesn't manage and turn to boot from the hard drive. I also tried wubi. I opened it through windows, got the window that asks me to choose "demo and installation" or "more on ubuntu" (something like that), I choose the first option, reboot manually my computer and it keeps returning on windows mode and doesn't boot from the cd. What can I do? Thanks!

• Not your typical Permission Denied Question

  - by Todd

  I recently reinstalled Ubuntu 11.10 (64 Bit) on my computer. (My hard drive took a powder) Before, I could "mv" files around with the command. Now when I try I get the permission denied message. I also get the message about "man sudo" when I open my terminal. I am pretty sure I did not get that before. Can I add a user/administrator and change something in my orginal admin that I cannot change myself? I am getting really frustrated with this. I do not recall having the same problem before. I tried qksudo nautilus and it appears to run then it sits there with the cursor blinking but does not move.

• 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!

• How to access UbuntOne when it asks for default keyring which has never been set?

  - by obu-tim

  I am trying to set up UbuntuOne on a new computer and after I enter the email and password, it asks for the keyring 'default'. I don't know what it is and I never set it. Makes it difficult to enter so it seems to be a counterproductive security default. I understand that if autologin is set the keyring is called. I tried setting the main user to need a password but if I reboot it doesn't ask for the password so it sort of autoboots still. So How do I set the keyring default password? If I can't set it I can't install UbuntOne

• Safest way (i.e. HTTPS, POST, PGP) to send decryption keys through the web?

  - by theGreenCabbage

  I am in the final stages of development for my Revit plugin. This plugin is programmed in C#, and distributed via a DLL. One of the DLLs is an encrypted SQLite database (with proprietary data) that is in the form of a DLL. Currently, in development stages, the decryption key for the SQLite database is hardcoded in my main DLL (the program's DLL). For distribution, since DLLs are easily decompilable, I am in need of a new method to decrypt the DLL. My solution is to send our decryption keys from our servers securely to the host's computer. I was looking in POST, thinking it was more secure than GET, but upon research, it appears it's similarly insecure, only more "obscure" than GET. I also looked into HTTPS, but Hostgator requires extra money for HTTPS use. I am in need of some advice - are there any custom solutions I can do to implement this?

• Does Ubuntu 12.04 supports for B75 boards?

  - by rail02000

  I want to build a new computer with Intel G840 CPU and Gigabyte B75M-D3H motherboard and install Ubuntu (or Kubuntu) 12.04 64bit on it. However, I'm worried about whether the chip is too new and whether that Linux Kernel now has support for it. According to the article [Phoronix] Intel Core i7 3770K Ivy Bridge Linux Performance Review ,the Linux kernel is ready to work on the chip. Existing Intel Sandy Bridge motherboards/chipsets are compatible with Ivy Bridge processors, but earlier this month Intel launched the new Panther Point chipsets that are already compatible with Linux too: the B75, H77, Z75, Z77, HM75, HM76, UM77, and HM77. But I didn't find further information or cases about running Ubuntu on the chip. So,is it OK to run Ubuntu on the board? Do I need to upgrade the kernel to a newer version (3.4 or 3.5 etc.) to get the system more smoothly? Or should I choose boards with H61 chip? Thank for your response!

• 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.

• Ubuntu Software Center is crashing while trying to install psychonauts

  - by GonzoDark

  I am having a problem installing Tim Schafers epic platform video game Psychonauts trough the Ubuntu Software Center. I have bought the game on http://www.humblebundle.com/ and I have used the new redeem option introduced in this bundle: "redeem your bundle on the Ubuntu Software Center." When I have downloaded approximately 2.1 GB of Psychonauts then Ubuntu Software Center starts to repeatedly crash and pop-up with a new crash report dialog every few seconds (before previous ones are closed and that will crash the computer after a few min, unless I stop the download). I also have a file-size bug, where Ubuntu Software Center tells me that I have downloaded 880,2 MB out of 133,3 MB I use the new Ubuntu 12.04 LTS and Ubuntu Software Center version 5.2.2.2 (©2009-2011 Canonical <--- That is also a bug, should be 2012 I guess) I hope someone can help me.

• Xubuntu and other Debian based distros slow

  - by William V

  I have a Compaq Presario SR1950NX desktop computer with the AMD64 3800+ processor and 1GB ram and it seems that Ubunutu, Xubuntu and Lubuntu are all laggy. Things seem to be slow such as clicking on menus and opening programs and the UI renders in peices. When using the browser the system slows down considerably. I ran the TOP command and I do notice that xorg hits 30 to 40 percent cpu when running the browsers. I have tried these distros on a spare P4 machine and it is even worse. As long as I don't have a several things open at one time I can manage to get around although sluggishly. I also notice that I can't get debian based distros to install in 64bit (crtc6 failure) only in 32bit. Can anyone tell me what is it that I might be doing wrong? I have an integrated Nvidia card and have tried several of the recommended drivers which sometimes result in no boot screen upon reboot. Thanks

• eth0 not working on startup

  - by user4106

  Hi to all, This might sound strange but, working with my Lubuntu 10.04 i've experienced troubles when connecting to my eth0 newtwork. After some googling, i've found out that by writting in the CLI the following command: mii-tool eth0 -F 10baseT-FD and activating the eth0 in the toolbar (by clicking "activate eth0") everything works just fine. Well, up to now, i did not have any problem, because every time i turned on the computer i had to do this, but it was very little effort.But now, i would like to use the machine as a file server, accesing it by ssh, without monitor or keyboard. So, i won't be able to make this actions, and can't do this at startup because mii-tool needs root permissions. So, the question is: Do you know what does that command do, and how can id make that change permanent? Or do you know any other solution for my problem? I hope i was clear! If not, tell me and i'll try to be as clearer as possible. Thanks in advance!

• Leapfrog Crammer won't mount as a USB flash drive

  - by William

  I can't seem to get the Leapfrog Crammer study and sound system to show up as a flash drive under ubuntu so I can transfer stuff to it. I don't want to install the leapfrog bloatware, can someone help me with this? Additional Information: When I plug my crammer into my computer it shows a 1 MB file system with a link to download the crammer software. I want to know how to access the rest of the crammer's file system so I can transfer music to it. The crammer does not show any other partitions in natulius. According to an article on the internet, the crammed is divided into three partitions: One with a link to install the crammer software, one with all content(music, flash cards, etc.) and one for firmware. I want to know how to access the one with the content so I can add music to the player. Can anyone help me with this? Thanks in advance.

• Cannot get grub menu to timeout (or go away)

  - by Eric

  I am running Ubuntu 12.04. I cannot for the life of me get the grub menu (with options) to go away. I would like it to auto-boot into the first option. I've edited /etc/default/grub so that it looks like the following: GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" After this, I ran sudo update-grub. Then I realized that I had grub 2, so I ran sudo update-grub2 (both make it look like they create the grub.cfg file successfully. I restart my computer and it goes back to the grub menu and just sits there until I make a choice. This is not desirable if the power goes out... :-) I also tried reinstalling grub using sudo grub-install /dev/sda - also unsuccessful

• Upgrade to Ubuntu 13.10 disabled track pad, brightness, sound on Lenovo Z570

  - by Vizir

  I just upgraded to Ubuntu 13.10 using Ubuntu's software update. It seemed to go all right, however after the system restarted and booted up Ubuntu 13.10, it began experiencing several problems. Some of them were due to expected conflicts with the updated OS, however right now I cannot figure out why certain hardware functions are now "broken" and how to fix them. As far as I can tell, these are the sound (permanently muted), mic (picks up no sound), brightness (set at maximum brightness regardless of using keyboard shortcuts or moving the screen brightness slider) and trackpad (mouse does not move, however plugged-in USB mouse does) This sounds to me like a driver issue, however I cannot figure out how to re-enable my drivers, re-install them, or whatever I have to do here. This did not happen durring my upgrades from 12.04 to 12.10, or 12.10 to 13.04, so I'm at a total loss as to why this happened this time around. My computer is a Lenovo Z570, dual-booting Ubuntu and Windows 7 from GRUB 2. Windows is working fine as far as I can tell.

• 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. Possible useful information: Using http://www.ubuntu.com/download/desktop/windows-installer Dual-booting with Windows

• Is it viable to become a contract programmer straight out of college?

  - by M G

  I have a Bachelor of Science in Computer Science and four months research experience designing and implementing a research project. I realize this is highly dependent on my skill set - which includes C, C++, Java, Python, and SQL. I feel I have an advantage in two ways: I am young and am not afraid to work overtime. I am willing to take lower pay to gather a client base/experience, and work nights/weekends to get a few projects under my belt. This may be cliche, but I feel that I can learn new technologies quicker than most. At the very least, I am not a slow study. With this being said, is it viable for me to become a contract programmer? Or do I need the 10+ year skill set that most contractors bring to the table?

• compiz problems - no effects work, despite the fact that they seem to be properly configured

  - by user97551

  I've looked through some posts about compiz and either haven't found the answer, or haven't understood what's been said. Could someone help me out? I installed ubuntu 12.04 through windows 7 (so I can dual boot) and installed compiz and set up the settings I want (hotcorners etc). For a while it seemed like it was going fine, but then I restarted the laptop, none of the compiz settings were working and the auto-launcher wasn't even coming up when I passed cursor over it. The computer is still usable, when I 'dash home' the auto-launcher appears, and I can tab through windows but yeh... the auto-launcher and hotcorners I set up through compiz aren't working at all. Any ideas? Oh, whilst I'm super grateful for any help I can get, I'd really appreciate it if you could keep any instructions as basic as possible. I'm a bit new at this... THANK YOU!

• 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!

• Logout or shutdown shows terminal

  - by N.N.

  When I logout or shutdown the terminal (the one I reach with Ctrl Alt + F7) is sometimes shown before the login screen appears or before the computer is shut off. Is there a way to stop this behavior? More explicitly. If I logout the terminal is sometimes shown for a second before the login screen appears. Also, sometimes when I shutdown (from within Unity or Gnome) the terminal is shown, sometimes for the whole shutdown process or just for a second or two. I've had this problem throughout 10.04, 10.10 and 11.04 and I've always used the standard Ubuntu variant. I've also noticed this happening on a fresh install of Natty on a friends netbook, so it's not local to my computers.

• Verb+Noun Parsers and Old School Visual Novels [duplicate]

  - by user38943

  This question already has an answer here: How should I parse user input in a text adventure game? 6 answers Hi I'm working on a simple old school visual novel engine in Lua. Basically I have most of the code set up besides one important feature. The Text Parser. Lets get into how words are generally structured. In the screenshot I input the command "my wish is for you to die" --How would a human understand this? my = noun/object wish = verb is = connective_equator similar to = for = connective_object (for all objects of ..) you = noun/object to = connective_action similar to do die = verb --the computer can then parse this and understand it like this (pseudo example) my = user you = get_current_label() you = "Lost Coatl" wish = user_command user_command = for all_objects of "Lost Coatl" do die() end execute user_command() What other ways do videogames use text parsers, what would be the simplest way for a newbie coder such as myself?

• About to graduage from good school without any progamming skills

  - by newprint

  Not sure if it is good place to ask this question, but found this section to be suitable. I am about to graduate from good school (in the US) with Computer Science degree, having good grades and high GPA. I have no freaking clue how to write a good program, how to properly test it... nada, zero. We were never been tough how to write software. Ye, sure the Comp. Architecture class is important, and I can tell you a lot about how MIPS processor works, and I can tell you about Binary Trees and Red-Black Trees and running time of operations in Big Oh, but it has nothing to do with programming in "real" life. For god sake, none of my classmates know how to use STLs or write templated code !!! To be honest, I found that many of my classes to be waste of time. What should I do ? How to step into real life and learn how to program ?

• 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.
