• How to set an environment variable called CLIENTIP?

  - by eKek0

  I was trying to use the sentence Environment.SetEnvironmentVariable("CLIENTIP", <value>) but it didn't work. I used both an string variable and a constant to set the value. So, how can I do this to work?

• Getting touchpad to work in desktop ubuntu

  - by kamziro

  I bought a small touchpad to stick on top of the keyboard, and it works fine on the windows computer, but not on my ubuntu desktop. I mean, when I do "xinput list" it shows the following: ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ? PIXART USB OPTICAL MOUSE id=8 [slave pointer (2)] ? ? Logitech USB-PS/2 Optical Mouse id=11 [slave pointer (2)] ? ? Microsoft Wired Keyboard 600 id=13 [slave pointer (2)] ? ? Macintosh mouse button emulation id=14 [slave pointer (2)] ? ? Cirque Corporation 9925 AG Touchpad id=15 [slave pointer (2)] ? Virtual core keyboard id=3 [master keyboard (2)] ? Virtual core XTEST keyboard id=5 [slave keyboard (3)] ? Power Button id=6 [slave keyboard (3)] ? Power Button id=7 [slave keyboard (3)] ? No brand SP04-A1 id=9 [slave keyboard (3)] ? Elite Silicon USB Audio Device id=10 [slave keyboard (3)] ? Microsoft Wired Keyboard 600 id=12 [slave keyboard (3)] The Cirque Corporation touchpad (I'm assuming that's the component name) is the touchpad. Is there anything I'm missing?

• After upgrading to trusty, ALSA midi connection (aconnect) doesn't seem to work right

  - by SougonNaTakumi

  Previously in kubuntu 13.10 I was able to open vmpk or plug in a midi keyboard, and provided that TiMidity was running in server mode, I could run aconnect [keyboard port (129:0 for vmpk)] 14:0 aconnect 14:0 128:0 and I could play the keyboard and get sound. But now, a while after upgrading to trusty, I tried to do that, and didn't get any sound. TiMidity itself still plays files fine, but if I try to play them with aplaymidi, I still just get silence. Oddly, the midi files are clearly being read. When I ran (where 130:0 was vmpk's input port) aplaymidi -p 130:0 ~/path/to/midi.mid vmpk was highlighting notes on the piano as if it were playing the midi. One time I tried this, TiMidity (?) very briefly played a fraction of a second of the first chord of my song before everything went silent and vmpk just highlighted the first voice on the keyboard as usual. Now the weirdest part of this is that probably about 40% of the time, when I've played at least one note with either aplaymidi or vmpk, when I run aconnect -x I get a sudden burst of a note or chord from my speakers (that is, if I played one note, I get a note; if I played multiple sequential notes, they turn into a chord), as if the notes were being queued up but not being played and that somehow liberated them. I have no idea what's going on there. A little while ago I remember having a problem with Audacity playing wav files sped up and also locking up if I tried to pause it, which it stopped doing when I set the audio devices to the actual audio devices rather than pulse. But now when I checked again, it's doing the opposite: it won't play audio at all and/or acts weirdly if I don't set the audio devices to pulse, and either way will very occasionally randomly do the speeding up thing regardless. Oddly in the midst of what's looking like a pretty screwed up sound system, sound in VLC and Firefox has been working fine and if I play a wav file with aplay ~/path/to/sound.wav that works fine too. Any idea what I could do to figure out what's wrong with ALSA and/or fix it?

• How does font rendering actually work?

  - by Andrea

  I realize that I know essentially nothing about the way fonts get rendered in my computer. From what I can observe, font rendering is generally made in a consistent way throughout the system. For instance, the subpixel font hinting settings that I configure in my DE control panel have influence on text which appears on window borders, in my browser, in my text editor and so on. (I should observe that some Java applications show a noticeable difference, so I guess they are using a different font rendering mechanism). What I get from the above is that probably all applications that need font rendering make use of some OS (or DE)-wide library. On the other hand, browsers usually manage their own rendering through a rendering engine, that takes care of positioning various items - including text - according to specific flow rules. I am not sure how these two facts are compatible. I would assume that the browser would have to ask the OS to draw a glyph at a given position, but how can it manage the flow of text without knowing beforehand how much space the glyph will take? Are there separate calls to determine the glyph sizes, so that the browser can manage the flow as if characters were little boxes that are later filled in by the OS? (Although this does not take care of kerning). Or is the OS responsible for drawing a whole text area, including text flow? Does the OS return the rendered glyph as a bitmap and leaves it to the application to draw that on the screen?

• Facebook integration in Empathy doesn't work in 12.10

  - by skerit

  The new web apps feature is fun, I've set up everything as it should be, but Empathy still doesn't connect to Facebook. When I go to the "Online-accounts" dialog and open the Empathy options dialog in the Facebook tab this shows up: Identification is blank and can't be edited Alias is blank, but can be edited A notification saying "Go online to edit your personal data" is visible I've tried logging into Facebook using my email address AND my username, both with the same results.

• gnome-file-share-properties doesn't work

  - by Riccardo Magrini

  I've configured gnome-file-share-properties on all my Ubuntu's PC for sharing the directory Public to each other. I following some guide found on Internet for the configuration of it, all explain the same procedure but in my case I don't see any Public directory shared with the PC. Following this link http://library.gnome.org/users/gnome-user-share/stable/gnome-user-share-getting-started.html.en I'd see the directory Public plus the name of PC that shares its directory on Nautilus Places. In my case I don't see anything, therefore on the Network place see all the machines 'n if I try to click on one receive this: "DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)" note: I don't want to use Samba because I've all Ubuntu PC, and the firewall is disabled on all PC.

• Canon Multitasking printer: Scanner doesn't work, printer does

  - by Holger Böttcher

  Model: Canon Prixma MG2260 I have installed to ubuntu 14.04 Trusty Tahr. Now I have the problem by my multi function device. The printer works, but the scanner doesn't! I have downloaded the Linux software of Canon for the 2200 series. I have downloaded the software of the Internet site of Canon. 6 Zip folder 3 deb. and 3 rpm. Always 1 for computer, 1 for scanner, 1 for other Thinks. I can load them on my PC and unpacking, but they do not install themselves. Does any person know what I have to do about this?

• Which programming language suits a system that must work without user input

  - by Ruud

  I'm building a prototype of a device that will function much alike a digital photoframe. It will display images retrieved from the internet. The device must start up and run the photoframe. It will have no user interface. The device has a minimal ubuntu installation, but I could install Xorg or whatever needed. Question: I have trouble figuring out which programming language will be suitable. I've just started using Python to try out several things and I am able to download and display images. I guess that means Python can do what I'd like, but is it suitable as a language that will be run on boot without any user interference? Related questions: - How do I set up Linux to start that script automatically? - How to setup a second Python script as a server that runs in the background to retrieve images before they are displayed (Because I think I'll need threading of some sort?)

• Both Webmin & ISPConfig won't work on my Ubuntu Linode

  - by SERVE-U

  I followed the steps on this page to download and setup Webmin on my Linode Ubuntu server, however, when I try to visit https + my.ip.add.ress + :10000, the page just hangs and nothing loads. I already looked into my firewall settings. I uninstalled Webmin and installed ISPConfig and all its dependencies, and the same thing happens at https + my.ip.add.ress + :8080. This is my first time managing a server so there could be something I overlooked. But my server is a pretty vanilla Ubuntu 12.10 with LAMP stack installed exactly as per the instructions in Linode's documentation.

• Will Ubuntu 11.04 work on my old pc?

  - by M4tic

  It has an old SiS based graphics chip with 64mb memory, there were never 3D drivers for them. Ubuntu 10.10 doesn't even boot on it and my laptop, a Lenovo N200 with intel 9something graphics 128mb so I'm really worried. Broadband prices don;t come cheap in South Africa so the download has to be worth it. I can wait for the shipment but I've since orderd 10.10 and it hasn't come, so I don't know if I'm barred from using that service since I've been sent a disc every release.

• This for array colllision function doesn't work with anything but first object in array

  - by Zee Bashew

  For some reason, this simple simple loop is totally broken. (characterSheet is my character Class, it's just a movieClip with some extra functionality) (hitBox, is basically a square movieclip) Anyway: every time hitBox make contact with a characterSheet in a different order than they were created: Nothing happens. The program only seems to be listening to collisions that are made with o2[0]. As soon as another hitBox is created, it pushes the last one out of o2[0] and the last one becomes totally useless. What's super weird is that I can hit characterSheets in any order I like.... public function collisions(o1:Array, o2:Array) { if((o1.lenght>=0)&&(o2.length>=0)){ for (var i = 0; i < o1.length; i++) { var ob1 = o1[i]; for (var f = 0; f < o1.length; f++) { var ob2 = o2[f]; if (ob1 is characterSheet) { if (ob2.hitTestObject(ob1)) { var right:Boolean = true; if (ob1.x < hitBox(ob2).origin.x) right = false; characterSheet(ob1).specialDamage(hitBox(ob2).damageType, hitBox(ob2).damage, right); }}}}}} Also it might be somewhat helpful to see the function for creating a new hitBox public function SpawnHitBox(targeted, following, atype, xoff, yoff, ... args) { var newHitBox = new hitBox(targeted, following, atype, xoff, yoff, args); badCollisionObjects.push(newHitBox); arraydictionary[newHitBox] = badCollisionObjects; addChild(newHitBox); }

• How do references work in R?

  - by djechlin

  I'm finding R confusing because it has such a different notion of reference than I am used to in languages like C, Java, Javascript... Ruby, Python, C++, well, pretty much any language I have ever programmed in ever. So one thing I've noticed is variable names are not irrelevant when passing them to something else. The reference can be part of the data. e.g. per this tutorial a <- factor(c("A","A","B","A","B","B","C","A","C")) results <- table(a) Leads to $a showing up as an attribute as $dimnames$a. We've also witnessed that calling a function like a <- foo(alpha=1, beta=2) can create attributes in a of names alpha and beta, or it can assign or otherwise compute on 1 and 2 to properties already existing. (Not that there's a computer science distinction here - it just doesn't really happen in something like Javascript, unless you want to emulate it by passing in the object and use key=value there.) Functions like names(...) return lvalues that will affect the input of them. And the one that most got me is this. x <- c(3, 5, 1, 10, 12, 6) y = x[x <= 5] x[y] <- 0 is different from x <- c(3, 5, 1, 10, 12, 6) x[x <= 5] <- 0 Color me confused. Is there a consistent theory for what's going on here?

• Sudo apt-get update -f does not work?

  - by BrianO09

  I am a bit of a noob with Linux. Several months ago I updated to Ubuntu 12.04, then stopped using Ubuntu for a while for a variety of reasons. Now I would like to go back to it, but I have a couple of problems. For one thing, the Software Center will simply not load. I click on the icon, the program comes up, but it never loads, and when I close it I get a "window not responding" message. While reading some threads to fix this issue, the common theme was that the main solution was to update by running: sudo apt-get install --reinstall software-center However, when I run that, I get the following (long): bcoleary@ubuntu:~$ sudo apt-get install --reinstall software-center [sudo] password for bcoleary: Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: kdelibs-bin : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkjsapi4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed kdelibs5-plugins : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkjsapi4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkntlm4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed kdoctools : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkcmutils4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkde3support4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkpty4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkdeclarative5 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkdewebkit5 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkdnssd4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkemoticons4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkfile4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkhtml5 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkjsapi4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkidletime4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkio5 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkjsembed4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkjsapi4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkmediaplayer4 : Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libknewstuff3-4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libknotifyconfig4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkparts4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkrosscore4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libktexteditor4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libnepomuk4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libnepomukquery4a : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libnepomukutils4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libplasma3 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libthreadweaver4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed E: Unmet dependencies.

• Can't get my Blue Snowflake Mic to work

• How to work with scenes in a 2D game

  - by Anearion

  I'm a java/android programmer, but I don't have any experience in game programming, I'm already reading proper books, like "Pro Android Games", but my concerns are more about the ideas behind game programming than the techniques themselves. I'm working on a 2D game, something like Cluedo to let you understand the genre. I would like to know how should I act with the "scenes", for example, a room with a desk, TV, windows and a lamp. I need to make some items tappable and others not. Is it common to use one image (invisible to the user) with every different item a different color, then call the getColor() method on the image? Or use one image as background, and separate images for all the items? If the latter, how can I set the positioning? and should I use imageView or imageButton? I'm sorry if those are really low quality questions, but as "outsider" ( I'm 23 and still finishing my university ) it's pretty hard learn alone.

• Network: Incoming connections work, outgoing fails

  - by anirvan

  i recently set up my own server at home to run Ubuntu 12.04 server ed. on booting up, i noticed that a message related to networking comes up, and the booting process pauses. the message read something like - waiting for network configuration and after a while - waiting another 60 seconds... on booting up, I realised that any command which requires a network connection was not working - ping, apt-get install, etc. on firing the ifup eth0 command, I get the error RTNETLINK answers: File exists. Failed to bring up eth0. I also realised, while searching the web for this problem, that this is probably one of the most common networking related issues - however, most of the questions are around setting up multiple IPs for the same machine. ifdown eth0 also fails, stating that eth0 is not configured. my /etc/network/interfaces file has a simple configuration for a static IP: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address xx.xx.xx.xx netmask xx.xx.xx.xx broadcast xx.xx.xx.xx gateway xx.xx.xx.xx dns-nameservers xx.xx.xx.xx The strangest part of this problem is that, while I can't connect to anything outside, I can ping to this particular server using the static IP configured in the interface file, and, i can even SSH into it! I'm really at ends here with this problem, and any guidance is much appreciated. Thanks!

• HP mini 5102 Ethernet does not work after suspend on Lubuntu 12.10

  - by Marcin

  Ethernet works fine after system is rebooted The onboard card is seen in 'lspci' as: 43:00.0 Ethernet controller: Marvell Technology Group Ltd. Yukon Optima 88E8059 [PCIe Gigabit Ethernet Controller with AVB] (rev 11) After system being suspended the sky2 driver loads but does not enable the NIC. I have noticed that it happens when PC is left suspended for longer period of time (few houres) Trying to reproduce it I have tried to load the sky2 driver with 'modprobe sky2'. Unfortunately typing 'ifconfig -a' for the onboard ethernet adapter does not list the driver once the sky2 driver is loaded. I have searched internet and I found some information about a bug in kernel. Hovewer it was reported in 2010 so I hope it has been fixed. Here it is http://lists.opensuse.org/opensuse-bugs/2010-02/msg01473.html

• Alsa doesn't work in vlc

  - by freebird

  Alsa Audio Output works fine from terminal, e.g. aplay /usr/share/sounds/alsa/Noise.wav. But I got to change from default to Alsa Audio Output in vlc. I found it in Tools Perfernces Audio Outputs. The issue is that when I change it to Alsa, I Loose all sound. When I leave the default I get an annoying Audio delay of about 200ms or 500ms. From what I have found you have to use Alsa Audio Outpu to fix that issue. Updated 6-26-2011 10:28pm To fix the Alsa Audio Output: sudo add-apt-repository ppa:ferramroberto/vlc sudo apt-get update sudo apt-get install vlc mozilla-plugin-vlc then, opened Update Manager, there were 2 updates for vlc there, I installed them and rebooted. Now alsa works fine and audio is in sync with video.

• Getting the Dell XPS 16 Synaptics touchpad to work after hibernation

  - by Aron Rotteveel

  I am currently experimenting with using Ubuntu as a my main OS instead of Windows 7. So far, pretty much everything is working fine, except for an issue that I am having with my touchpad. I have a Dell XPS 16 (1640) with a Synaptics touchpad. It works out of the box, but it seems that it stops working after returning from hibernation mode. This problem has also been addressed in an earlier bug, but judging from this bugreport, it should be fixed by now. I am running the 2.6.35-23-generic-pae kernel. Any ideas?

• dig @server doesn't work

  - by JustTrying

  I have Ubuntu 12.04 with BIND9, working just as a caching server (forwarding to 8.8.8.8). When I use, for example, dig +norecurse @l.root-servers.net www.uniroma1.it, I obtain the following output ; << DiG 9.8.1-P1 << +norecurse @l.root-servers.net www.uniroma1.it ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached Using Wireshark I discovered that the outgoing queries are correct, but there aren't any incoming answers. Why? P.S. Using simply dig www.uniroma1.it I obtain the correct answers.
