• Why is it taking so long to open the Ubuntu Help Center?

  - by Agmenor

  When I click on the Help Center Icon in the 'System' menu, it takes more than a minute to launch the program. More than a minute, for a text only program seeming like a website! All my other programs work fine, and I saw this problem also on other computers. Is there a reason for this? Will it be fixed? I think it is an important issue for beginners. As a response to Scaine, the result of the command software-center is the following: Traceback (most recent call last): File "/usr/share/software-center/update-software-center-agent", line 72, in <module> db = xapian.WritableDatabase(pathname, xapian.DB_CREATE_OR_OVERWRITE) File "/usr/lib/python2.6/dist-packages/xapian.py", line 3195, in __init__ _xapian.WritableDatabase_swiginit(self,_xapian.new_WritableDatabase(*args)) xapian.DatabaseLockError: Unable to acquire database write lock on /home/agmenor/.cache/software-center/software-center-agent.db.tmp: already locked 2011-01-11 19:57:24,495 - softwarecenter.app - INFO - software-center-agent finished with status 1

  - by John Baber

  I recently upgraded my desktop mac to Precise and now can't get past the Ubuntu 12.04 splash page. The splash freezes with [ 19.931097] b32-phy0 ERROR: Firmware file "b43/ucode16_mimo.fw" not found [ 19.9311126] b32-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all instructions on this website. written on it This is when I choose 3.2.0-generic from the grub menu. If I choose to load up older kernels, I still get the same thing. How can I make my computer finish booting again? I'm able to ssh into the machine and poke around, but the actual screen freezes at the splash.

• Copy and Paste problems in Visual Studio 2010

  tweetmeme_source = 'alpascual';After installing Visual Studio 2010 I started having problems with Copy and Paste. Trying to find out how many users are being affected by this bug. The use case to reproduce the bug, just using VS2010 for a few minutes and eventually doing Control C and Control V to copy lines of code does not work. Using the menu to do the copy and paste also wont work. Looks like a problem in the clipboard itself IMHO. The set up of my computer.

• How to distribute applications?

  - by Dr Deo

  I am new to Ubuntu development. As a learning experience, I have written a custom chat application using qt4 and I want to deploy it in some sort of setup file. Whats the easiest way of deploying an application viz a viz setting desktop icons. automatically requesting for administrator privileges to execute. inserting an entry into the startup menu. automatically compress my application and reduce download size. automatic startup for my application without user intervention I am familiar with using NSIS scripts on Windows, but I don't know where to begin on Ubuntu. I would preffer a solution similar to NSIS scripts.

• How to adjust DPI in 14.04

  - by jake

  I asked about fixing DPI in 12.04. The 14.04 release notes list "Support for High-DPI screens and desktop scaling." Post upgrade, it seems that nothing has changed. Similar symptoms from my previous post persist: The 1" square here is closer to 1/2" Despite the line xserver-command=X -dpi 170 in /etc/lightdm/lightdm.conf, xdpyinfo reports 96x96 dpi I did find that I was able to use the "Scale for menu and title bars" slider in System SettingsDisplays to fix title bar text size instead of setting org.gnome.desktop.interface text-scaling-factor as described here. The last post also mentions that in Gnome 3, DPI is hard coded to 96. Is this a limitation in 14.04? (I am somewhat ignorant to the distinction between Gnome and Unity) Can I do anything to properly set my DPI?

• System doesn't boot when ubuntu is installed on an SSD

  - by Caetano Nichnich Nunes

  I've recently discovered Ubuntu and decided to give it a try. I am using a Samsung Series 5 p530u3c-ad1 which comes with a 24gb SSD and a ~500gb HDD, My intention is to set the system files to the ssd and the rest to the HDD. The system works fine if I do a direct install using only the HDD, but if I try using the SSD for the system files the computer doesn't boot-up, I do not know if the SSD is being recognized by the computer, I think so because I could install Ubuntu on it, but it doesn't appear on the boot order or the boot menu. I read some posts and tried using boot-repair which pointed me not to forget to set my system to boot from my SSD, unfortunately I cannot because of the issues mentioned above. Thanks for your time.

• First time using Ubuntu, need help with drivers!

  - by Nick

  I have just successfully built my first computer last night. I went through the boot menu and got Ubuntu 12.10 installed properly and everything. My question is...now what? There has to be some sort of drivers I need to install right? I can't connect to wi-fi or anything of that sort. I have an ASUS motherboard, model number M4N98TD EVO , and an NVIDIA Geforce GTX 650 grpahics card. I guess my main question is, can someone run me through step by step what I need to do after I install Ubuntu?

• Ubuntu runs really slow on netbook

  - by Tim

  so I installed Ubuntu through Wubi in my netbook (Compaq Mini, 1.6 GHZ Atom, 1 GB RAM, 250 HDD, Windows 7 Starter) and decided to keep the original OS and run both... The thing is that, after I installed Ubuntu (really hyped: a couple of friends told me this OS was amazing, much faster and eaiser to use than Windows) and selecting it from the boot menu, I find that it runs really slow, sometimes freezing for a sec... For what I know, there must me be a partition in C:/ and a lot of HDD space for the Installation Size to make things faster, but I am sure I got those things right... Any help?? Also, why doesn't Wubi ask you for the DVD or bootable USB drive?? I'm just new in all this guys...

• How can I reduce the time taken to login by postponing/delaying some startup applications?

  - by koushik

  I have setup some applications to startup on each login (e.g., redshift-gtk, gtg) automatically but after adding these to startup applications (System -> Preferences -> Startup Applications) obviously the time taken to login has increased. Due to all this the time it takes for my panels, desktop etc to appear is too long - until which I am forced to wait. I don't need these apps to be available immediately, but it would be good if they startup eventually, meanwhile the ubuntu menu/panel is available for running other apps that I might need to. I tried using at command, with the intention of editing all startup applications to put the commands in the at queue, but this didn't work since the apps don't get the necessary environment variables (like DISPLAY). Is this what nice command is used for? Any other ideas how I can accomplish this? If possible, I would like to avoid editing the startup applications commands, since this would mean a lot of effort to replicate on other machines I use.

• How do I rename a mounted Truecrypt volume?

  - by invert

  When I mount the Truecrypt file on my USB drive it shows up as truecrypt1. The volume is FAT, using mtools to rename a volume label involves e2label /dev/sdbx, however truecrypt1 does not map to a physical partition. fdisk -l does not show the volume partition (only the physical USB device), and df -h lists the volume path as /dev/mapper/truecrypt1. Finally, using the Nautilus 'Rename' context action, gives the error: "Sorry, could not rename "truecrypt1" to "towel": Operation not supported by backend". Apparently this can be done in Win, but how can I rename this volume in Ubuntu? As Nicolas said, specifying the mount point names the partition the same. The truecrypt GUI does not remember the mount point I set, so I specify the mount points in a script which I placed in my main menu. #!/bin/bash gksudo truecrypt /media/usbdrive/encryptedfile /media/securedata/

• Synonyms for different languages in LibreOffice Writer? [closed]

  - by cipricus

  Possible Duplicate: How do I add English-UK thesaurus in LibreOffice? When setting a text for English US the context menu contains 'Synonyms' This is not the case for the other languages for which I have the spelling installed (English UK, French etc) Can I have the Synonyms option for UK English too, for example? Even that is a problem although there seems to be solutions around for it. Here, for example, (which is a link to here) but after testing it cannot see synonyms for uk. Also this which was reported as a solution is not working anymore it seems. What about other languages? (Please notice that this question is not just about English-UK. I have initially noticed that 'synonyms' where missing in relation to British, but I am asking about how to solve the issue in general or, when there is no general solution, how to solve it on a case-by-case basis. For the meta consequence of all this, involving the issue of it being a duplicate, see comments under here and this question.)

• Boot delay and mouse lag at login after Ubuntu 12.04 update

  - by Roshan George

  I am facing these weird problems after updating Ubuntu 12.04 with apt-get update && apt-get upgrade: It takes too much time to come to the Plymouth theme after selecting Ubuntu from the grub menu. Is it possible to correct this? On the login screen, before entering the password, whenever I move the mouse, it is kind of lagging/stuck. Only after entering the password and pressing Enter, it works normally. I think this may be because of the updated kernel. If so, is it possible to downgrade the kernel to the previous one ? If that is not the reason, what can be the problem?

• Skype on Ubuntu 12.04 x64 - anyone has it installed?

  - by Zevaka

  I am wondering if there's anyone here who managed to use skype @ 12.04. It used to work (ever since i first tried Ubuntu 10.04) flawlessly, but after upgrade to 12.04 just doesn't start. If I start skype from terminal, it just says "Segmentation fault (core dumped). I tried to remove skype and installed it from different locations: Skype website (did not install at all, "package error") From official Ubuntu repository (doesn't start at all, segmentation fault) From repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner" (doesn't start at all, segmentation fault) Interesting thing: even if I remove / purge skype from the system, it still shows up in Unity menu (of course doesn't start). Any help here? Thanks!

• navigation menus and SEO

  - by Rodolfo

  I've always have my doubts about navigation menus effect on SEO. You know, the vertical menus on the top that show in every page in the site linking to main sections and subsections. My issue is that if not done dynamically (i.e. after page is loaded or something), from a search engine's point of view it probably looks like a whole bunch of links in the beginning of the page, and links that probably have nothing to do with the page being analyzed, so it's probably not only confusing it, but also giving link 'juice' to the wrong pages or reducing its value. When I've asked SEO people about this, I usually get a "Google is smart, they'll recognize it as a menu and ignore it" response, but I'm not convinced (and the 'Google is smart' argument sounds almost like religion discussion to me). So does it affect SEO negatively or not? Are there any official posts on this topic?

• Question about JPanel "transition" for Java Swing

  - by user16778

  I want to make like a sort of main menu (in GUI). When the user clicks the start button, the screen transition into another "screen" (JPanel). This image will make it easier to understand. http://i.imgur.com/Cfdry.png Currently, I have a MainMenu extends JPanel and that gets added into a driver class with a JFrame. I can't figure how to switch to another class like Game extends JPanel. So when the user clicks the start button in MainMenu, I want it to somehow hide itself and the Game to show itself. Thanks.

• How do I change the Google Chrome offline icon?

  - by user1105047

  I am using some offline apps for google chrome and because of this an application indicator pops un in the gnome panel. My problem is that this indicator uses the google chrome default system tray icon and I think it looks ugly with my current theme so I would basically like to change the icon. I can't find the icons that google chrome is using for this purpose but I have no problem finding the other icons used by google chrome and changing them, like the 24x24 or 22x22 icons that you see in the gnome application menu (which by default looks like the application indicator for google chrome). It doens't seem like Google Chrome is taking the icon from e.g /usr/share/icons/ and I can't change the icon by changing the icon theme in like gconf-editor Is there anyway to see the preferences (like you can do with launchers) of the application indicators in the gnome-panel and then locate the indicator icon or change it in another way?

• How do I stop Banshee from putting a notification in the panel for every song?

  - by Dave M G

  As a playlist or internet radio station plays, a notification pops up in the top right corner every time the song changes. I can't find any way either within Banshee or settings in general to stop this. How do I stop Banshee from putting a notification in the panel for every song? Further, can I stop Banshee from outputting any notifications at all? Update: I tried going into Banshee ? Edit ? Preferences ? Extensions, and disabled the Sound Menu Integration, but this does not seem to stop notifications.

• How to reboot into Windows from Ubuntu?

  - by andrewsomething

  I'm looking for a way to reboot into Windows from Ubuntu on a 10.10/Vista dual boot system. The specific use case is that I would like to be able to ssh into my running Ubuntu instance and issue a command that will initiate a reboot directly into Windows. I found a promising blog post, but the script that it suggests isn't working: #!/bin/bash WINDOWS_ENTRY=`grep menuentry /boot/grub/grub.cfg | grep --line-number Windows` MENU_NUMBER=$(( `echo $WINDOWS_ENTRY | sed -e "s/:.*//"` - 1 )) sudo grub-reboot $MENU_NUMBER sudo reboot man grub-reboot isn't much help, but it seems to be leading me in the right direction: set the default boot entry for GRUB, for the next boot only WINDOWS_ENTRY=`grep menuentry /boot/grub/grub.cfg | grep --line-number Windows` MENU_NUMBER=$(( `echo $WINDOWS_ENTRY | sed -e "s/:.*//"` - 1 )) echo $MENU_NUMBER This returns the expected value, but on reboot the first menu entry is still highlighted. Any ideas why this isn't working or suggestions for other solutions?

• Can I toggle word-wrapping on/off quickly in Gedit?

  - by Ivan

  Depending on nature of the text, some times line wrapping is convenient, some times it is just confusing. And every time I need to switch this (pretty frequently) I have to do to View - Preferences - Enable text wrapping - Close - 4 clicks, not mentioning all the hand, eye and thought motion. Can this be done a quicker way? Most of text editors have this 2 clicks away (in a menu) at maximum, some have it on a toolbar or a hot key, but I couldn;t find any quick way in Gedit :-( Maybe there is a hot key I don't know?
