• Sound works for only one user at a time

  - by Patrick

  I've noticed that sound becomes unavailable to me when someone else is logged into my machine and playing music (or has facebook open) in the other account. I've had to ask them to unlock their account and turn it off so I can get sound in my own stuff. Even in sound preferences, the hardware itself disappears and output is "dummy sound". Is there a way to prevent this from happening? What would be really good is if I could turn down the volume (or mute entirely) all the sounds on all other accounts on a per-user basis from my sound preferences without affecting whatever setting they have - essentially saying whenever user A is logged in, all sounds from user B's account are muted and anything from user C's account is at 50% while I can still have my own at full volume.

• How to make bash script run with a latency (i.e. wait 1 sec at each iterations)?

  - by user2413

  I have this bash script; for (( i = 1 ; i <= 160 ; i++ )); do qsub myccomputations"${i}".pbs done Basically, I would prefer if there was a 1 second delay between each iteration. The reason is that at each iterations, it sends the program file mycomputation"${i}$.pbs to a core node for solving. Solving in this instance involves the use of pseudo random numbers. I suspect the RNG I use (R's) uses CPU time as seed because as things are now I get repeating pseudo random numbers (at the rate of approx 1 out of 100). So how to you ask bash to for (( i = 1 ; i <= 160 ; i++ )); do wait 1 sec qsub myccomputations"${i}".pbs done

• Dimming the backlight is irreversible on a Samsung Q210 notebook, what do I do?

  - by user27304

  I'm new to the community, although I have been using Ubuntu since 2010. I have a Samsung Q210 notebook; Specs: Intel® Core™2 Duo CPU P8400 @ 2.26GHz × 2 4 Gigs RAM Nvidia 9200m GS (although system information in Ubuntu doesn't know) 194 GB HD OS: Ubuntu 11.10 Kernel is 3.0.0-12-generic-pae Although Samsung seems to be infamous for problems with Ubuntu, after upgrading to Oneiric, finally the FN Brightness Buttons are recognized. The only problem is, after dimming the backlight for a fixed amount of steps (3 or 4, I dare not count now because that would mean rebooting because I can't see anything), the display goes completely dark and using the FN buttons to brighten the backlight does not work anymore (before reaching that threshold, going brighter after dimming works). Now what do I do? File a bug report? If not, what then? If yes, how? Not sure... guess I should ask here first.. thanks for answering in advance.

• Right-click acts too fast - No Fix Yet, Any Workaround?

  - by Aahan Krish

  When I click the right mouse button (anywhere, be it - desktop, browser, console, etc.), the right-click context menu pops up so quickly that the very *first* option in the menu gets clicked. This happens too often to take it easy. This issue has been brought up a couple of times on Ask Ubuntu, but with no fix whatsoever. This is a very low priority issue for the Ubuntu team, I believe? (How could they?!) Is there at least a workaround for the issue? Ubuntu is almost unusable for me as it is now. PS: I have a new mouse. So, please don't go about suggesting that I get a new one - - everything's working fine on Windows 7, so should be the case with ubuntu 11.10, which it is not.

• The /usr/bin/x11 folder

  - by WrecklessT

  Why does the /usr/bin/x11 folder hold another x11 folder and when you open that === x11 you get another x11 and then another and another??? I did it about 6 times and got frustrated so I have no idea how deep this goes but What is the purpose (or is it a glich?)? Is this eating disk space more than it should? (I was going to delete one or more but thought I better ask first before I end up !fucked ) and finally Is it just me and I am going crazy maybe the pills are wearing off or maybe they are kicking in.. I am not sure but an answer would help. I can see no reason why this should be happening at all.

  - by el10780

  I would like to ask if there is any good program for ubuntu 12.04 to organize a library of books.I have to mention that I have books written on my native language (Greek) and I have books written in other languages like English,French,etc....So basically I need an application which can fetch information from databases for Greek books.For example add a Greek (ISBN) book database source and when I type the ISBN of the book in the program to find the book from that database/es.Do you know if this is possible?I have already tried Tellico and GCstar but they were unable to find books with Greek ISBN.I tried to add a Greek book source but my wasn't successful.

• Any way to list similar commands?

  - by Septagram

  When you write the command name wrong, bash often does this: septi@norbert:~$ good No command 'good' found, did you mean: Command 'gold' from package 'binutils' (main) Command 'gmod' from package 'gmod' (universe) Command 'goo' from package 'goo' (universe) Command 'god' from package 'god' (universe) Command 'geod' from package 'proj-bin' (universe) Command 'gord' from package 'scotch' (universe) good: command not found Or sometimes it does this: septi@norbert:~$ nftp No command 'nftp' found, but there are 23 similar ones nftp: command not found Is there any way to ask bash to show these 23 similar commands for me? And, is there a way to show similar commands, including those that aren't yet installed, instead of running the application, ftp for example?

• How to interview a natural scientist for a dev position?

  - by Silas

  I already did some interviews for my company, mostly computer scientists for dev positions but also some testers and project managers. Now I have to fill a vacancy in our research group within the R&D department (side note: “research” means that we try to solve problems in our professional domain/market niche using software in research projects together with universities, other companies, research centres and end user organisations. It’s not computer science research; we’re not going to solve the P=NP problem). Now we invited a guy holding an MSc in chemistry (with a lot of physics in his CV, too), who never had any computer science lesson. I already talked with him about half an hour at a local university’s career days and there’s no doubt the guy is smart. Also his marks are excellent and he graduated with distinction. For his BSc he needed to teach himself programming in Mathematica and told me believably that he liked programming a lot. Also he solved some physical chemistry problem that I probably don’t understand using his own software, implemented in Mathematica, for his MSc thesis. It includes a GUI and a notable size of 8,000 LoC. He seems to be very attracted by what we’re doing in our research group and to be honest it’s quite difficult for an SME like us to get good people. I also am very interested in hiring him since he could assist me in writing project proposals, reports, doing presentations and so on. He would probably fit to our team, too. The only question left is: How can I check if he will get the programming skills he needs to do software implementation in our projects since this will be a significant part of the job? Of course I will ask him what it is, that is fascinating him about programming. I’ll also ask how he proceeded to write his natural science software and how he structured it. I’ll ask about how he managed to obtain the skills and information about software development he needed. But is there something more I could ask? Something more concrete perhaps? Should I ask him to explain his Mathematica solution? To be clear: I’m not looking for knowledge in a particular language or technology stack. We’re a .NET shop in product development but I want to have a free choice for our research projects. So I’m interested in the meta-competence being able to learn whatever is actually needed. I hope this question is answerable and not open-ended since I really like to know if there is a default way to check for the ability to get further programming skills on the job. If something is not clear to you please give me some comments and let me improve my question.

• How do you show the desktop in a blink in Ubuntu?

  - by e-satis

  We know you can either click on the show desktop icon or use CTRL+ALT+D to ask Ubuntu to show the desktop. Unfortunately, this does not always show the desktop in one action. Sometime, and this is true for at least the last 4 version of the OS, it brings up first to the front all the windows, THEN, with a second click, show you the desktop. This is very annoying, as when you show the desktop it generally to quickly click on a shortcut. To understand what I'm talking about, open 7 windows, minimize some, bring some to the front, maximize one, then show the desktop. Then do that on Windows. You'll see the difference.

• I'm getting a black screen right after Install Ubuntu option on GRUB menu. Any ideas?

  - by Silight

  I've formatted my USB and remade the live USB twice. I tried editing editing the commands (pressing the 'e' key while the command was highlighted on the GRUB menu) by 1. deleting quiet splash and replacing it with nomodeset 2. adding nomodeset right before quiet splash 3. deleting quiet splash and adding radeon.modeset=0 I saw another solution for a fix by editing GRUB but in command line 'sudo' 'nano' and 'update-grub' all show up as unknown commands. I'm brand new to Ubuntu, in case you couldn't tell. I would appreciate any help you could give me. I want to convince my brother that Ubuntu is a better option than iOS but I can't do that if I can't install it. If you need more information, please ask. I'm not dual booting. I want this to be a full install. Thanks.

• New file in ubuntu kernel ppa repository to install?

  - by Nikki Kononov

  Googling this question hasn't brought me to anything so I decided to ask here. Recently I noticed on kernel.org that kernel 3.7 finally considered to be a stable so I decided to upgrade, since I am on 3.7 RC7 but when I opened http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7.1-raring/ I noticed new file (actually 2 which seems to be identical) linux-headers-3.7.1-030701-omap_3.7.1-030701.201212171620_armhf.deb and linux-image-3.7.1-030701-omap_3.7.1-030701.201212171620_armhf.deb so my question is should I install those as well or continue installing only 4 files (e.g. 3 AMD64 image and headers + all headers)? Thank you.

• How do I get unity back?

  - by Siva

  I got the latest driver software for my old ATI Radeon 4600, and it had me restart. My screen was then just a big terminal! I could log in, but when I typed 'unity' into it as a command, it said something about DISPLAY not found; set it to :0 (zero). I don't know enough about Linux to deal with this. I am using a DSL live CD to ask this. I looked at similar questions suggested, even searched. If my question's a duplicate, I apologise, but I didn't understand what I saw there. T_T

• 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.

• How to connect to the internet via command line or graphical utility given I can't click at the top of the screen?

  - by Ben

  My Ubuntu 12.04 installation has an input problem resulting preventing me from clicking near the top of the screen. That is, there is an unclickable area, circa 60 pixels high and stretching all the way across the screen. I will ask about this in a later question. For now, I would just like to be able to connect to the internet, given this limitation. I am able to access the network connections application by hitting the super key and typing "network connections". There is a LAN and a wireless network available. The network icon in the bar at the top of the screen shows an empty wedge, which I suppose means that wireless is off. I've attached the cable for the Ethernet connection, but it does not seem to have connected automatically. How can I figure out what's going on? (I'll happily edit in the output of any relevant terminal commands.) Thank you.
