• Xmonad Xsession

  - by AntLord

  My user level: noob-ish, so please bear with me I'm running 12.04 LTS. I have installed and, to some extent, configured xmonad 0.10 The "automagically" created xsession for it works fine as it is, but when I login it won't run a startup script I've created and "call from" /usr/share/xsessions/xmonad.desktop, if that's right. I've read pretty much all I could find about .xinitrc and .xsession, I tried that and it somehow messed up the other "sessions", if I'm explaining myself correctly. Had to $unity --reset to have the "main session" working again. Anyway, my question is, how do I autostart xmobar and set a desktop background after login into xmonad's default Xsession? I tried this script, start-xmonad: #!/bin/bash # #I only used one of the following each time I tried, none worked #Also, do I really need the '&'? I know what they're for, but... nitrogen --restore & feh --bg-scale ~/Pictures/picture.png & #Then I want xmobar to start, again do I need the '&'? I know it's for it to run #in the background, but I tried removing the '&' and xmonad still launched xmobar & #Finally, the only thing that seems to work in this script exec xmonad Yes, I made sure I did chomd +x ~/start-xmonad The xmonad.desktop is [Desktop Entry] Name=XMonad Encoding=UTF-8 Comment=Lightweight tiling window manager Exec=/home/myusername/start-xmonad Icon=custom_xmonad_badge.png Type=XSession So, this didn't work, now I'm here. Please help :s thanks

• I don't know how to connect to the internet

  - by Michiel

  I'm having some trouble finding an answer to my problem. I have a dell desktop (studio hybrid) and i have windows vista on it. The internet on windows vista works great, no problem. But now i downloaded Ubuntu 11.10 and I'm having problems. I can't find how to connect to my wireless network, when i click the network icon, it shows a list of things but I can only click 'enable wireless network' or something like that and 'edit connections'. But in this list it also says ( in a grey collor and i can't click it ) : 'No wireless connection, device not ready (firmware missing)" Or something like that. Now i tried several things i read on the internet (using my vista OS cause i can't use ubuntu for the internet, which is really enoying). But none of them helped me. I would like someone to tell me what my problem is or what information I have to give you to get an answer. So tell me if i have to edit a connection, or tell me how i have to get the wireless connection to work and to repair the 'firmware missing problem'. I hope someone can/is willing to help me. Bye

• How can I add a custom item to the Sound Indicator (and make it clickable more than once)?

  - by con-f-use

  The original question One of the strength of Unity are the various standardized indicators. I want to customize the sound indicator with an additional menu entry that runs a small shell script. I'm not afraid of a little Python code and I hope someone can point me to the right subroutine in the right file. I suspect that will be fairly easy but all the indicators are just so bloated that I can't look through their code in a reasonable time. Any help is appreciated. I know it is possible as the marvelous Skype-Wrapper does it. Edit 2 - Now a dirty DBus hack The one click problem from one edit before has now turned into a DBus problem. Basically we have to tell the sound indicator that our bogus player has terminated now. A dirty hack navigates around that problem: #!/bin/bash # This is '/home/confus/bin/toggleSpeaker.sh' notify-send "Toggle Speaker" "$(date)" qdbus \ com.canonical.indicator.sound \ /org/ayatana/indicator/service \ org.ayatana.indicator.service.Shutdown exit 0 Help from the community is appreciated as I don't have experience any with DBus whatsoever. Edit 1 - Takkat found a solution but only clickable once? For some reason the solution proposed by Takkat has the drawback that the resulting entry in indicator sound can only be clicked once per session. If someone has a fix for, than please comment or answer, you will be upvoted. Here you can see the result: I strongly suspect the issue is related to the .desktop-file in /home/confus/.local/share/application/toggleSpeaker.desktop, which is this: [Desktop Entry] Type=Application Name=toggleSpeaker GenericName=Toggle Speaker Icon=gstreamer-properties Exec=/home/confus/bin/toggleSpeaker.sh Terminal=false And here is a minimal example of the script in /home/confus/bin/toggleSpeaker.sh for your consideration: #!/bin/bash # This is '/home/confus/bin/toggleSpeaker.sh' notify-send "Toggle Speaker" "$(date)" exit 0

• Slick2d Spritesheet showing whole image

  - by BotskoNet

  I'm trying to show a single subimage from a sprite sheet. Using slick2d SpriteSheet class, all it's doing is showing me the entire image, but scaled down to fit the cell dimensions. The image is 96x192 and should have cells of 32x32. The code: SpriteSheet spriteSheet = new SpriteSheet("images/"+file, 32, 32 ); System.out.println("Horiz Count: " + spriteSheet.getHorizontalCount()); System.out.println("Vert Count: " + spriteSheet.getVerticalCount()); System.out.println("Height: " + spriteSheet.getHeight()); System.out.println("Width: " + spriteSheet.getWidth()); System.out.println("Texture Width: " + spriteSheet.getTextureWidth()); System.out.println("Texture Height: " + spriteSheet.getTextureHeight()); Prints: Horiz Count: 3 Vert Count: 6 Height: 192 Width: 96 Texture Width: 0.75 Texture Height: 0.75 Not sure what the texture dimensions refer to, but the rest is entirely accurate. However, when I draw the icon, the entire sprite image shows scaled down to 32x32: Image image = spriteSheet.getSprite(1, 0); // a test image.bind(); GL11.glEnable(GL11.GL_BLEND); GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA); GL11.glBegin(GL11.GL_QUADS); GL11.glTexCoord2f(0,0); GL11.glVertex2f(x,y); GL11.glTexCoord2f(1,0); GL11.glVertex2f(x+image.getWidth(),y); GL11.glTexCoord2f(1,1); GL11.glVertex2f(x+image.getWidth(),y+image.getHeight()); GL11.glTexCoord2f(0,1); GL11.glVertex2f(x,y+image.getHeight()); GL11.glEnd(); GL11.glDisable(GL11.GL_BLEND);

• Huawei e303c data-card not working for Ubuntu 11.04?

  - by Umashankar

  Cheers to you. I got a problem in making a Mobile-BroadBand connection in Ubuntu 11.04, using 'Huawei e303c' usb data-card. I'm using Tata Docomo 3G sim-card (India, circle: Maharastra). My observations: 1.) I installed the device's driver 'Mobile-Partner For Linux'(which came up with the device). But it is not detecting my device. 2.) In Network Manager, Adding a Mobile-BroadBand connection is not able to detect the device (with or without the device's driver installed). 3.)I tried softwares like usb_modeswitch, gnomeppp, wvdial, sakis3G and followed their guidelines. These too didn't work. 4.) Without the driver, the system is able to identify the device (Mobile-Partner icon comes-up, that leads to driver setup files). But after installing the driver, nothing comes-up there. 5.) In all the above cases, when 'lsusb' cmd is fired, the prompt shows the connected data card (as 'DEVICE_ID:VENDOR_ID Huawei Technologies Ltd.,'). This is my problem. Give a solution to get my device connected. -Umash

• Connect to bluetooth device from command line

  - by Ilari Kajaste

  Background: I'm using my bluetooth headset as audio output. I managed to get it working by the long list of instructions on BluetoothHeadset community documentation, and I have automated the process of activating the headset as default audio output into a script, thanks to another question. However, since I use the bluetooth headset with both my phone and computer (and the headset doesn't support two input connections) in order for the phone not to "steal" the connection when handset is turned on, I force the headset into a discovery mode when connecting to the computer (phone gets to connect to it automatically). So even though the headset is paired ok and would in "normal" scenario autoconnect, I have to always use the little bluetooth icon in the notification area to actually connect to my device (see screenshot). What I want to avoid: This GUI for connecting to a known and paired bluetooth device: What I want instead: I'd want to make the bluetooth do exactly what the clicking the connect item in the GUI does, only by using command line. I want to use command line so I can make a single keypress shortcut for the action, and would't need to navigate the GUI every time I want to establish a connection to the device. The question: How can I attempt to connect to a specific, known and paired bluetooth device from command line? Further question: How do I tell if the connection was successful or not?

• Video game "Gish" will only launch from command line

  - by aberration

  Platform: Lubuntu 11.10 x64 Program: Gish When I try to launch Gish from the command line (/opt/gish/gi.sh), there are no problems. But when I try to launch it from the LXDE menu, it will not start. Contents of /usr/share/applications/gish.desktop: [Desktop Entry] Categories=Game;ActionGame;AdventureGame;ArcadeGame; Exec=/opt/gish/gi.sh Path=/opt/gish Icon=x-gish Terminal=false Type=Application Name=Gish I tried changing Terminal=false to Terminal=true to debug it, but then I just got a blank terminal, and the game didn't start. Edit: Here is some additional information, as requested by Eliah Kagan below: I tried editing /usr/share/applications/gish.desktop, as recommended, but it had no effect However, ~/.xsession-errors contained the following error: [: 8: x86_64: unexpected operator ./gish_32: error while loading shared libraries: libGL.so.1: wrong ELF class: ELFCLASS64 I think there's a problem with the /opt/gish/gi.sh shell script. This is its contents: cd /opt/gish/ MACHINE_TYPE=`uname -m` if [ ${MACHINE_TYPE} == 'x86_64' ]; then ./gish_64 else ./gish_32 fi I'm not too familiar with Bash, so hopefully someone else can point out the error. I have a 64-bit machine. I think that when the script is run from the command line, it's properly launching the 64-bit version (/opt/gish/gish_64), but when it's run from the LXDE menu, it's launching the 32-bit version (/opt/gish/gish_32), which is causing the libGL.so.1 error. However, this may be related to my libGL.so.1 problems with 2 other games.

• Ask the Readers: What Do You Have Set as Your Homepage?

  - by Mysticgeek

  When if comes to setting a homepage in your browser, it’s really based on personal preference. Today we want to know what you have set as your homepage in your favorite browser. Browser Homepage There are a lot of search sites that allow you to customize your homepage such as iGoogle, MSN, and Yahoo. Some people enjoy having a homepage set up as a dashboard of sorts. While others like simplicity and set it to Google or leave it blank. Not surprisingly in a small office or corporation you will see a lot of workstations set to MSN or the company SharePoint site. Unfortunately, a lot of free software tries to change you default homepage as well, like in this example when installing Windows Live Essentials. Make sure to avoid this by not rushing through software install wizards, and carefully opt out of such options. What is set as your homepage in your favorite web browser…both for work and at home?

• C# Cursor stuck on busy state

  - by Ben

  So I implemented a fixed time step loop for my C# game. All it does at the moment is make a square bounce around the screen. The problem I'm having is that when I execute the program, the window doesn't allow me to close the program and the cursor is stuck on the busy icon. I have to go into visual studio and stop the program manually. Here's the loop at the moment public void run() { int updates = 0; int frames = 0; double msPerTick = 1000.0 / 60.0; double threshhold = 0; long lastTime = getCurrentTime(); long lastTimer = getCurrentTime(); while (true) { long currTime = getCurrentTime(); threshhold += (currTime - lastTime) / msPerTick; lastTime = currTime; while (threshhold >= 1) { update(); updates++; threshhold -= 1; } this.Refresh(); frames++; if ((getCurrentTime() - lastTimer) >= 1000) { this.Text = updates + " updates and " + frames + " frames per second"; updates = 0; frames = 0; lastTimer += 1000; } } }

• How do I get an application to appear as a choice in update-alternatives?

  - by Jay

  I separately installed the Firefox Beta and Alpha channels, and have desktop configuration files pointing to them in ~/.local/share/applications. However, stable Firefox is being used as my default browser by the system. (Firefox Beta used to be used until I messed with the "Default Applications" in System Settings, where it is not listed.) I tried running sudo update-alternatives --config x-www-browser to manually change it, but it's only recognizing Chromium and Firefox (stable) and showing them as a choice. What can I do to get custom desktop configuration files in ~/.local/share/applications to be seen as default alternatives? I think I may have to fiddle with the desktop config files, or with mimeinfo.cache or mimeapps.list? Running Oneiric. Here is the content of the firefox-beta.desktop file I created: [Desktop Entry] Name=Firefox Beta Exec=firefox-beta -P Beta -no-remote Icon=firefox Terminal=false X-MultipleArgs=false Type=Application StartupNotify=true StartupWMClass=Firefox Categories=GNOME;GTK;Network;WebBrowser; Comment[en_US]=Firefox Beta Channel MimeType=text/html;text/xml;application/xhtml+xml;application/xml;application/vnd.mozilla.xul+xml;application/rss+xml;application/rdf+xml;image/gif;image/jpeg;image/png;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/ftp;x-scheme-handler/chrome;video/webm; Name[en_US]=Firefox Beta [NewWindow Shortcut Group] Name=Open a New Window Exec=firefox-beta -new-window about:blank TargetEnvironment=Unity

• Shutdown issue on persistent LiveUSB

  - by John K

  A) Downloaded Ubuntu to a Windows 7 temp directory from: http://www.ubuntu.com/download/ubuntu/download (Ubuntu 11.10 - Latest version / 32-bit). The output was a .iso file. B) Created a bootable USB stick using Universal USB Installer: http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/. Did not select "Persistent file". Result: Tried it in a Dell Latitude D630 Dell laptop: works every time, many startups and shutdowns. C) Repeated B) but with "Persistent file" set. Works once or twice, but then, just locks on the Ubuntu splash screen. E) Downloaded LiveUSB Install from http://live.learnfree.eu/download, which created a file on Windows 7 called live-usb-install-2.3.2.exe. F) Ran the above installer with "Persistent file" to a 4GB ScanDisk (formatted) thumb drive. Result: Worked pretty good for a while. Shutdown and rebooted several times. Changed items like creating a new directories - all worked. Then: Setup an Admin account with a password and no auto login. On next reboot, it required the password and logged in correctly. Tried to shutdown via the top left icon - Shutdown menu option. Key issue: Would not shutdown, but would always go back to the login prompt. Could successfully login. Finally, shutdown (which just put me back to the login window), and hard shutdown with the power switch. Result: On reboot, just locks on the Ubuntu splash screen. Questions (note, very new to Linux): Did I shutdown wrong (I mean prior to the hard power off)? Is the persistence option very unstable, or am I doing something else completely wrong?

• Is it possible to keep nm-applet running between invocations of WM startup?

  - by serverninja

  I am using nm-applet to interface with NetworkManager, running xmonad as a window manager. My X sessions (including nm-applet) are set up with a /usr/local/bin/xmonad.start script. My question is, how can I keep nm-applet running in the background as long as X is running, but not necessarily xmonad? As mentioned above, it is being started with xmonad (and dying with it when xmonad is restarted, etc). I am using gdm to manage my X sessions, and I'm running 10.10. Where's a good place to start nm-applet to suit my particular needs? I need to remove it from the control of xmonad, but don't know where to start it otherwise. Any help, tips, etc appreciated. Edit: problem seems to be with how I have integrated xmonad. I have the session script as a file in /usr/share/xsessions/xmonad.desktop with the following contents: [Desktop Entry] Encoding=UTF-8 Name=XMonad Comment=Lightweight tiling window manager Exec=/usr/local/bin/xmonad.start Icon=xmonad.png Type=XSession /usr/local/bin/xmonad.start contains the following: #!/bin/bash xrdb -merge ~/.Xresources xcompmgr -c & trayer --edge top --align right --SetDockType true --SetPartialStrut true --expand true --width 8 --heighttype pixel --height 18 --transparent true --alpha 0 --tint 0x000000 & gnome-settings-daemon & gnome-screensaver & if [ -x /usr/bin/nm-applet ] ; then nm-applet --sm-disable & fi /usr/bin/urxvtd -q -o -f & eval `ssh-agent` & if [ -x /usr/bin/gnome-power-manager ] ; then sleep 1 gnome-power-manager & fi /usr/bin/gnome-volume-control-applet & exec xmonad The question is how do I integrate xmonad, gdm, X, etc in such a manner to replicate the behavior I currently have except with nm-applet (and possibly other programs) running whether or not xmonad is?

• How can I assign actions to all my mouse buttons?

  - by Torben Gundtofte-Bruun

  I have a mouse with lots of buttons, but it's not a mainstream make like Logitech. For Windows, I have a driver that lets me assign actions like close-window (Ctrl+W) or next-tab (Ctrl+Tab), but I don't have a Linux driver. Since Linux is so flexible, I thought perhaps there is a general way to do this, regardless of brand? Update: Based on input from Cyrex, I installed and ran sudo apt-get install btnx which found several but not all mouse buttons. Found: left, right, wheel, wheelclick, thumb fwd, thumb back. Not found: wheel left, wheel right, thumb middle button. Vendor ID is 0x04d9, Model ID is 0xa015. Update 2: In SystemPrefsMouse there's a lightbulb icon for testing double-click speed. Every working button can turn the bulb on&off, but the missing buttons can't. It would seem that Ubuntu isn't aware of these buttons and thus doesn't register their clicks. I guess I need to hunt for a driver, though a mainstream mouse is probably the easier way.

• How to prevent window list "confusion" when detaching eclipse views?

  - by amotzg

  I'm detaching eclipse views to float on my other screen in order to get more coding space on the first screen. When doing that, the detached windows appear in ubuntu's window list applet with the eclipse icon but with no title. Then, when pushing the main eclipse button on the window list, one of the detached views will get to front but not the main eclipse window. When using Alt+tab I can also see the extra eclipse icons but choosing the correct one for the main window works and make it the active window while also showing all detached childs. Other applications behave as expected, e.g. gimp floating panels don't show on the windows list and this is also the case with SlickEdit, Firefox child windows all show on window list but gets the focus correctly, etc. I can see the the workspace switcher show my two screens but in 'Monitor preferences' I see my two screens as one big screen. I'm working with ubuntu 10.04.4 under a VMware Workstation 7.1.3 build-324285. 'uname -a' output: Linux ubuntu 2.6.32-40-generic #87-Ubuntu SMP Tue Mar 6 00:56:56 UTC 2012 x86_64 GNU/Linux The desktop screen shot with the problem, ununtu's version, and Monitor preferences. How can I solve it and make only the main window show in window list or at least get activated when pushing it's button on the window list?

• How to install Tor (Web Browser) in Ubuntu 12.10?

  - by Zignd

  I would like to install the Tor, but I'm having some problems. I know that someone will say "This question is a exactly duplication of How to install tor?", but it's not, because the another question can not be applied to Ubuntu 12.10 as the deb command is not available anymore. I did a research and even at the Tor's Official Website the available resource can not be applied to Ubuntu 12.10. I tried to use the deb command (as the above question says: deb http://deb.torproject.org/torproject.org <DISTRIBUTION> main) and the Terminal says deb: command not found and when I try to install it says E: Unable to locate package deb. I've also tried to use the ppa: ubun-tor, but it's not compatible with Quantal Quetzal, because it's too old. I've also tried to use sudo apt-get install tor, but browser icon don't shows up after installation and if you try to use the command tor in the Terminal I get the following error message: Nov 26 10:59:25.731 [notice] Tor v0.2.3.22-rc (git-4a0c70a817797420) running on Linux.

• "Missing Operating System" after installing Ubuntu 12.04 from a CD on a Macbook Pro

  - by Pierre

  I followed this guide to install Ubuntu 12.04 on my Macbook Pro 8,2 (late 2011): https://help.ubuntu.com/community/MactelSupportTeam/AppleIntelInstallation I used a CD. I synced the partition table on rEFIt, and it went fine. I do have an icon to boot on Linux, but when I launch it, after a few seconds I have "Missing Operating System" displayed, and that's all... How can I fix that? The only thing I see is, in the guide, it is mentioned this: On the last dialog of the installer, be sure to click the “Advanced” button and choose to install the boot loader (grub) to your root Ubuntu partition, for example /dev/sda3. This will be the only partition with the EXT4 file system. In Ubuntu 12.04 installation process, there is not such an option, but there is a dropdown menu to select where the grub bootloader should be installed. It was /dev/sda by default, but I selected my root Ubuntu partition (in my case, /dev/sda5). I got a warning message (but actually, it was the same warning message even when I selected /dev/sda), and I continued the installation... Thanks in advance for your help!

• Why doesn't unity show icons or panel after installing numix theme?

  - by Sid

  I'm a beginner to Ubuntu/Linux and I have a problem: Unity is not loading! When I choose Unity in the log-in screen, I get notifications and I can see the mouse, but that's it. I have Ubuntu 14.04 installed, along with Bumblebee/Primus. I had no issues whatsoever, until I decided to try the numix-theme and the numix icon pack. I added the PPA and installed it, but when I logged off and logged back on, nothing showed up. I panicked, and in tty1, I purged numix-* but that did not solve the issue. To get by day-to-day use, I installed gnome-flashback, and among those environments, only the metacity one works. (The compiz one does not.) I've tried installing the unity-tweak-tool to reset unit, installing dconf and doing: dconf reset -f /org/compiz/ but that didn't work either. One site even told me to delete /org/compiz/, but that did not resolve the issue. When I checked ccsm, the Unity plugin had a check to it. I also tried with Unity doesn't load, no Launcher, no Dash appears, but it gets stuck on "loading icons". Any help will be awesome!

• Fastest way to parse big json android

  - by jem88

  I've a doubt that doesn't let me sleep! :D I'm currently working with big json files, with many levels. I parse these object using the 'default' android way, so I read the response with a ByteArrayOutputStream, get a string and create a JSONObject from the string. All fine here. Now, I've to parse the content of the json to get the objects of my interest, and I really can't find a better way that parse it manually, like this: String status = jsonObject.getString("status"); Boolean isLogged = jsonObject.getBoolean("is_logged"); ArrayList<Genre> genresList = new ArrayList<Genre>(); // Get jsonObject with genres JSONObject jObjGenres = jsonObject.getJSONObject("genres"); // Instantiate an iterator on jsonObject keys Iterator<?> keys = jObjGenres.keys(); // Iterate on keys while( keys.hasNext() ) { String key = (String) keys.next(); JSONObject jObjGenre = jObjGenres.getJSONObject(key); // Create genre object Genre genre = new Genre( jObjGenre.getInt("id_genre"), jObjGenre.getString("string"), jObjGenre.getString("icon") ); genresList.add(genre); } // Get languages list JSONObject jObjLanguages = jsonObject.getJSONObject("languages"); Iterator jLangKey = jObjLanguages.keys(); List<Language> langList = new ArrayList<Language>(); while (jLangKey.hasNext()) { // Iterate on jlangKey obj String key = (String) jLangKey.next(); JSONObject jCurrentLang = (JSONObject) jObjLanguages.get(key); Language lang = new Language( jCurrentLang.getString("id_lang"), jCurrentLang.getString("name"), jCurrentLang.getString("code"), jCurrentLang.getString("active").equals("1") ); langList.add(lang); } I think this is really ugly, frustrating, timewaster, and fragile. I've seen parser like json-smart and Gson... but seems difficult to parse a json with many levels, and get the objects! But I guess that must be a better way... Any idea?

We need to try to extract them in Microsoft word which come with Windows 7 (not Microsoft office word). Looking to this article http://www.techrepublic.com/blog/itdojo/save-images-in-microsoft-word-documents-as-separate-files/135 This article is only useful when you have Microsoft word installed. Now if I don’t have Microsoft office then what ? No problem, here is a trick. when you open the doc file in Word  then select the image and right click on image and choose cut. open the Microsoft paint. paste them here. Without clicking anywhere click on crop icon on toolbar.   Now you got your image in the same size as you have in word file. Don’t worry about Image format. Microsoft paint have support for save them in PNG format.

• The battery indicator in Unity panel not showing up

  - by user61415

  I installed Ubuntu 12.04 with Wubi. Well after being completely dazzled with the amount of free content in the Software Centre, I decided to go deeper and start messing with settings. Well after changing the screen brightness the highest level I noticed that there wasn't an indicator for how much battery was left in my laptop. I looked up online on got 2 suggestions on how to fix: Right click on the Unity panel and add an indicator Set it to show in the power settings menu. Well I did both when I right click at the top menu nothing comes up and setting it to show does nothing either. Then I tried installing something in the Software Centre. I got something but when I activated it it said I had 0% power left even though I was charging and at %100 according the Light in the front of my laptop. So now I'm thinking that it doesn't even recognise my computer as a laptop which is weird because in the display settings it says my screen size is set to laptop. How can I install it? I don't know what version it is other then Ubuntu 12.04 and no matter what the icon does not appear with the

• Is there an idiot's guide to software licensing somewhere?

  - by Karpie

  Basically, my knowledge on the issue is zilch other than the fact that open-source and closed-source exists. I'm a web developer (not a designer in the slightest), so I look online for things like icons. I've always been a big fan of these icons, which have a Creative Commons Attribution 2.5 License. As far as I can see, this license says 'do whatever you want with them as long as you have a link back to me somewhere'. Is that assumption correct? Just today I found a new icon set, with a much more confusing license (found here), and to be quite honest I have no idea if I'm allowed to use them or not. At the moment I want to just use them for toy stuff that might never see the light of day, but then my source code is stored on Github, is it legal to store the icons there where they're publicly accessible? If I put them on my personal website that might have ads on it to make me five cents every now and then, is that legal? If I use them on a site that offers a free service to users, is that legal? If that site then starts making money (via things like paid subscriptions) or gets bought out by someone (highly unlikely but one day possible) is that legal? Is there some noob guide out there that explains all this stuff, because I would hate to start using this sort of stuff now only to have to change it all later. Even if I buy the icons, there's still licensing issues that I don't understand! :( And this sort of stuff keeps popping up more and more often...

• Strange resolution on Ubuntu 11.10

  - by FSchmidt

  I only just installed Ubuntu 11.10, so excuse me if this question is silly ;-) I have a Fujitsu Esprimo Mobile V655, nvidia 8200 graphics, and recently installed Ubuntu 11.10 using wubi. I had to modify booting commands to include nomodeset; otherwise Ubuntu would not boot. Now I did set my screen resolution to 1280 x 720, which is the correct resolution for this screen. Still, the display seems imperfect. The font sizes seem unnatural(too large / stretched) and text is quite blurry (especially in Firefox). Could it have something to do withe the nvidia graphics driver and/or the nomodeset parameter? How can I fix this? Update: I used jockey-gtk to update nvidia to the current version. This improved the resolution dramatically (no blurriness, fonts are good). It also means that I no loger need to include nomodesetin the boot commands. However, other problems were brought up by this. It seems that certain files cannot be accessed - icon (images) are missing, some task bars are completely unstyled (grey, block-form, win97 style). I also get this error message(roughly translated from German, so may be slightly different from actual) every time I reboot: Could not apply the stored configuration for the monitor: none of the chosen modi is compatible with the available modi. I have tried nvidia-xconfig, unity --reset , no improvements. Can anyone help, please?

• Restore Default Appearance in Ubuntu 12.04

  - by katya sehgal

  I'd like the original colour scheme, icon style of 12.04. I somehow lost the Ambiance theme (possible error or upgrade error). I re-installed 'light-themes' from the terminal and got it back. But the panel on the top that shows the options of sound, battery and wi-fi has changed and I can-not get the original setting back. In the windows, the close, minimize tools have shifted to the right instead of the original left side. I had installed MyUnity and Ubuntu Tweak but deleted them. As such, I want the original setting back. Kindly help me with the commands. I have searched for solutions; there are multiple and I need to be sure if I should follow the same. Kindly bear before marking duplicate. Discoveries *. [The appearance is gray and boxy as outlined here.] Not sure same problem. *. [Similar 'gray and boxy' article here] *. Desktop forgets theme.] *. I have also tried unity --reset command. It never completes. I gave it 20 minutes.

• Plugged in, not charging&ndash;Windows 7

  - by Kelly Jones

  Just a quick post on something I ran into lately with my Dell Precision M4500 laptop (monster laptop!).  I noticed the little icon in the system tray for the power options was stating that it was “plugged in, not charging”.  I don’t know why it was stating this, but I quickly found a fix for it on the net. I found the fix in this forum on CNET.  Here’s the fix: In order to correct problems with the battery's power management software, follow the steps below. 1. Click Start and type device in the search field, then select Device Manager . 2. Expand the Batteries category. 3. Under the Batteries category, right-click the Microsoft ACPI Compliant Control Method Battery listing, and select Uninstall . WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver. 4. On the Device Manager taskbar, click Scan for hardware changes . Alternately, select Action > Scan for hardware changes . Windows will scan your computer for hardware that doesn't have drivers installed, and will install the drivers needed to manage your battery's power. The notebook should now indicate that the battery is charging.   And it did work.
