• problems with studying algorithms

  - by rookie

  hello everyone, I'm currently studying computer science at the Institute, and I have some problems with course which is named Algorithms, I've just begun to study it, but I'm already feeling, that I'm going to fail it, my problem is that while understanding different algorithms on graphs I need to keep in my mind a lot of info, and usually I can't do it, I forget some points of the exercise or can't proceed to final result, I'm very desperate about it cause I like programming very much. Did somebody feel the same while studying in the University? thanks in advance for any help P.S. I began to program only two years ago, may it be the problem?

• Keyboard freezes when xorg crashes

  - by gsedej

  Situation is like that. Many times has happened that Xorg freezes and with it also keyboard. Quite some times because of some Compiz effects or Flash (fullscreen switch). Keyboard becomes totaly unresponsive, while mouse still works (I can move cursor, but can't click since desktop freezes) and music still plays and I can connect trough ssh. This is the only way I know I can try to solve problem - either by killing browser&flash or lastly restarting xorg server. This problem appears on more than one Ubuntu computer. My home dekstop with proprietery nvidia driver, on my work where I use noveau driever (opensource driver for geforce) and sometimes (but rarely) also on laptop with ATI graphics (using r300g driver which is really good!). Can someone explains why mouse still works while I can't input from keyboard? (I can't switch to virtual console or do R-E-I-S-U-B command) I have USB keyboard and USB mouse.

• Need multiple sound outputs to multiple speakers

  - by Usman Sajeel Haider

  How do I play 3 different music tracks at the same time on my computer, such that song1 is played in speaker1, song2 in speaker2... Is this possible programatically? What additional hardware will I need? Do I need 3 seperate sound cards? Given that the hardware is in place, how would I "route" the sound output for a particular song to a particular speaker. Alternatively, is there a special hardware that can handle multiple inputs and outputs? Appreciate your expert opinions.

• Falied installing ATI X.Org binary driver!! (ATI Radeon HD 5400)

  - by Naveen

  The open source driver worked well with the fresh installation of Ubuntu 12.04, but it drains my laptop battery faster. So I installed the proprietary driver from jockey-gtk. It gave me this error message at the end of the installation: Here is the jockey.log After restarting the computer, I lost all the compositing animations. Compiz visual effects don't work. There is a black boarder around Docky. Please somebody help me...! Thanks!

• External display suddenly not detected

  - by NChase

  I have a Lenovo IdeaPad U410 running Ubuntu Desktop 13.04. I have an external monitor that I connect to via HDMI, and it's worked flawlessly for six months. I plug in my laptop, it detects the display. The "change display" key built into the laptop works for switching between the two screens. Never any problems. This afternoon, when I reconnected my computer after taking it into another room for a bit, it didn't work. When I open up Display settings, it can't detect the display. I tried disconnecting/reconnecting everything multiple times. And most strangely, that same "change display" key now behaves like a Super key, opening the dash instead of toggling the display. Nothing at all changed between when I plugged it in this morning and when it stopped working a few hours later. I tried xrandr, that doesn't detect it either. Anyone have any ideas?

• How to make JWM work in Ubuntu 12.04?

  - by alba

  I have installed the JWM on Ubuntu 12.04 via the Software Centre, but it doesn't work. When I choose the JWM session from LightDM, it only shows a black screen. It worked when I had another computer with Ubuntu 11.10, where I had the same problem after the JWM installation. But once, by chance, I chose to start JWM from a Fluxbox session. And after that, i was able to start JWM also from LightDM. But this solution does not work for me on Ubuntu 12.04. JWM never starts.

• It's hard to judge your own product. Is there a name for this issue?

  - by Epicmaster

  I was just talking to my partner about how hard it is to personally judge how good your product is after a while because you use it so often. You literally spend hours on your computer doing nothing but work on this Consumer Facing application, and you start to feel a little fatigue of using it over and over and over, at least a hundred times a day. You get scared this fatigue may mean the product you are building may have the same effect on the users and might mean you are doing something wrong. Is there a name for this in product development? For the fact that as a designer+ programmer+everything else, your product might not suck as much as you think simply because you spend way too much time with it, or a variation of this?

• Is there animation software available for Ubuntu?

  - by Robert Low

  Is there commercial-grade computer animation software available for Ubuntu, similar to the professional software sold for the Windows operating system? This question goes out to those of you who may be using such software professionally. My daughter recently graduated from the Art Institute of Seattle, and needs to put together an animation portfolio in order to interest employers in the field. As you know, such software is usually provided by the employer and the costs are high - several thousand dollars. I suggested that she investigate Ubuntu as a possible way to acquire the tools she needs. But, since I have no idea what might be available, either as open source or proprietary animation software, I am reaching out to the Ubuntu community for help in the hope someone who is using such software can help her. Thank you for reading this post, and for any information you might have.

• Ubuntu - prettier bootloader

  - by Matthew

  I hate how when I turn on the computer it just (after the hp logo, which I hate having also), shows white text on a black background. I'm wondering if there's easy ways to customize this (I'm choosing between Windows 7 and two separate Ubuntu 10.10 installs). I've read a little about some complicated ways to do this, but is there not some simpler ways by installing a package on ubuntu or something? I don't want to hack a bunch of code together to get a simple effect. I'm hoping for actual images and having like the windows 7 logo and ubuntu logo to choose from. Ideas?

• Can I run Ubuntu Live from a USB flash-drive without destroying the data on it?

  - by Lucian

  I already have a number of files on a flash drive (8 gb) that I would prefer to keep, but I would like to try Ubuntu even if merely for the aesthetics. I use Windows XP. I know that it's definitely possible to run Ubuntu from a bootable drive like my flash drive to try Ubuntu but I would much rather keep my files intact not only on my flash drive but also my hard drive, if that's possible. I also want to know if it's entirely possible that while running Ubuntu from the USB if I can switch back to Windows while my computer is still on. If I'm missing something, please let me know. I'm very grateful for any assistance in this matter.

• How to hide bind mounts in nautilus?

  - by Bazon

  Summary: How do I remove folders mounted via bind or bindfs in /etc/fstab from appearing as devices in nautilus left column, the "places" view? detailed: Hello, I mount various directories from my data partition via bind in /etc/fstab in my home directory, eg like this: #using bind: /mnt/sda5/bazon/Musik /home/Bazon/Musik none bind,user 0 0 #or using bindfs bindfs#/mnt/sda5/tobi/Downloads /home/tobi/Downloads fuse user 0 0 (Background: /dev/sda5 mounted to /mnt/sda5 is my old home partition, but I do not want to mount it as a home partition, as I always have at least 2 Linuxes on the computer ...) That works well, but since 12.10 every one of those items is listed in Nautilus in the left column under "Devices". (Where normally USB drives appear, etc.) This is a waste of space (as I have many of such mounts...) and so I would like to have these mounts hidden, just as it was before in 12.04. How can I do that? Thanks!

• Update drivers for TL-WN851ND

  - by Tony_GPR

  Today I bought a new PCI wireless card, TP-Link WN851ND, with Atheros AR9227 chipset. It has 2 antennas and is compatible with Wifi N so I thought it would improve the quality of the signal. But after install it on my computer the result is the opposite to expected. It doesn't connect to my network, while my old Wifi BG card connect without problems, I created an access point from my smartphone to try the card, and work, but is very slow loading pages. In Windows 7 works perfectly, so I think the problem is the driver. I have Ubuntu 12.04 LTS with kernel 3.2.0.31, is there a way to update the driver or I can apply a patch to improve the performance of the card? Otherwise, anyone know if there is a work in progress to improve compatibility with this chipset, or is it better to change the card and buy one with better driver compatibility. And finally, which wireless N compatible chipsets have good support under Linux/Ubuntu?

• What is the best tool to sync browser passwords and bookmarks?

  - by jgbelacqua

  Sadly, everything I've tried so far has been painful to manage between two computers, (even between different browsers on the same computer). So, right now I have different aggregations of bookmarks passwords in xmarks, delicious, google bookmarks, firefox sync, text files, and in figaro password manager (fpm2). I've also tried to use bindwood in the past. What I would like to do is merge all bookmarks and passwords into some solution that actually works either with tools available under Ubuntu, or with a browser-based tool (addon/plugin/extension) which works between between google-chrome/chromium, and firefox. It would be ideal if there was an ability to send and store passwords encrypted (if not on my own server). Whatever the method, I need the ability to have import from existing sources. (It doesn't have to be pretty, just repeatable.) It's possible that some things I've ruled out are now workable (e.g., xmarks broke for me at one point because I hit their bookmark limit for the server/account, and bindwood, firefox sync were firefox only).

• Where is the Accessibility mouse click lock?

  - by user10133

  I've been a user of Linux on the desktop off and on again over the years. I very nearly switched my primary computer to Ubuntu prior to the release of Windows 7. There were a few, but significant issues at the time that prevented wholesale adoption, mostly tethering with my phone and lousy VPN Client. One key component I could count on was the Accessibility features. I have recently installed Ubuntu 10.10 and am considering giving it another try, but it appears Ubuntu has taken a leap backwards in that it no longer has a click lock feature for the mouse. Basically I need the ability to press and hold the left button to trigger a locking of the button so I can move the mouse by way of a trackpoint with my prosthesis. I absolutely require this feature and it is a deal breaker if it won't work. I've tried the Dwell keys but this is a chaotic control at best. I've never been able to manage a drag of any kind.

• What route to take to become a systems developer?

  - by Ramin

  In the past I have done a lot of Java and Python coding. Mostly, I worked on web apps and some simple console or gui apps. I also have a formal education in computer science. What route should I take to become a systems developer? I always did like C++, but never had a chance to use it for anything. Would mastering C++ be one of the steps? If so what resources can you suggest? Also, I would like to know how much different is the work between plain old development and systems development. There seem to be a lot of overlapping between the two.

• WebLogic Application Server: free for developers!

  - by Bruno.Borges

  Great news! Oracle WebLogic Server is now free for developers! What does this mean for you? That you as a developer are permited to: "[...] deploy the programs only on your single developer desktop computer (of any type, including physical, virtual or remote virtual), to be used and accessed by only (1) named developer." But the most interesting part of the license change is this one: "You may continue to develop, test, prototype and demonstrate your application with the programs under this license after you have deployed the application for any internal data processing, commercial or production purposes" (Read the full license agreement here) If you want to take advantage of this licensing change and start developing Java EE applications with the #1 Application Server in the world, read now the previous post, How To Install WebLogic Zip on Linux!

• Picture lens doesn't find anything

  - by Han Cnx

  I get Facebook results, but nothing from my computer. If I open a terminal and use 'locate' then I can find stuff, but the picture lens is empty. Note that my picture files are on an NTFS partition. I have made a link named 'Pictures' in my home folder that points to the location where the picture files are. Again, this works with the 'locate' command and it also works for the Music lens, which is also a link in my home folder. It also (kinda) works for the Video lens, though it only wants to find videos I have opened, which seems not consistent with the other lenses. (and also not very useful this way)
