• Prevent gnome-shell's dash from listing Recent Items

  - by Vivek

  I am using gnome-shell in Ubuntu 11.10. I am getting annoyed when dash search lists Recent Items. I have tried many ways to prevent it like Deleting activity.sqlite and activity.sqlite-journal files under ~/.local/share/zeitgeist Adding all the possible entries in Activity Log Manager to prevent application logging Specifying time range in Activity Log Manager to forget my activities. But none of the methods are working. The recent items list is still populated. Is there any way to tell dash not to list Recent Items while searching, other than the above methods? Or is there any way to delete the recent items list?

• Why does tomcat-admin install require adding admin and manager to tomcat-users.xml manually?

  - by J G

  I installed tomcat6 on lucid using apt-get. All working. I installed tomcat-admin. Not working. I amended the /etc/tomcat6/tomcat-users.xml file to uncomment the users and roles (from the default) to be like the following: <role rolename="tomcat"/> <role rolename="role1"/> <user username="tomcat" password="password" roles="tomcat"/> <user username="both" password="password" roles="tomcat,role1"/> <user username="role1" password="password" roles="role1"/> This still didn't work. Then from the following page I added. <role rolename="manager"/> <user username="admin" password="secret" roles="manager"/> then it worked. Why doesn't this occur as part of the install? (Why isn't this in the Ubuntu Manual on Tomcat ?)

• Why can't I install 10.04 on a system that already has 8.04?

  - by Android Eve

  Ubuntu 10.04 is beautiful. I love it. I am dying to install it on my PC, alongside the existing Ubuntu 8.04 (from which I write this message right now). But... it won't let me! When I reach the partitioning stage (manual!) Ubuntu 10.04 sees my two HDDs as one RAID volume. It doesn't see all the partitions I already have in place in /dev/sda and /dev/sdb. Even Windows 7 doesn't behave like this... (yes, I actually managed to install Windows 7 64-bit in dual-boot configuration with Ubuntu 8.04 on this same system). Note: GParted on Ubuntu 10.04 (live CD) sees the partition intended for Ubuntu 10.04 (/dev/sda4) perfectly, but is unable to format it. Note: I also removed that partition trying to reformat it via GParted once 10.04 LiveCD is loaded. It didn't help. I believe that the problem lies in Ubuntu "deciding for me" that the HDDs should be "seen" as a RAID, hence any partition is seen by GParted as "busy" or "locked". Any idea how to solve this problem?

• Is it possible to save output from a command to a file after the command already has been executed?

  - by NES

  Does an elegant way exist to save the output of a command to a file after the command has been run, with the terminal window is open? I mean once the command has been executed in the terminal. The output is still there in terminal. Now i could copy & paste all the lines and save it to a file. But perhaps does a method exist to somehow write the output buffer of a terminal window to a file or even better the output of an already executed command?

• Evolution and thunderbird sharing same mail data?

  - by balki

  Hi, I have been using Evolution for a quite long and it has downloaded around 1.6GBs of mails from gmail. I want to try thunderbird but I dont want to re download everything again. Is that possible to have both clients sharing same data? I'll make sure I don't use both at the same time if that matters. I'll move to thunderbird fully if I'm happy with it. Problems I face with evolution is that I have to have the GUI running always if I want to get instant alerts and send mail immediately. Also it loads the messages slow and even after I move to the next mail, it slowly downloads all the linked images before moving on.

• Problem with Ubuntu and UEFI (Problem with any linux OS)

  - by K.T.Sumant

  I have purchased a new Sony Vaio laptop and it is said that the Windows in the recent laptops is installed in the UEFI mode. But all the Linux OS are installed in default in Legacy mode. When I reboot my laptop, Ubuntu is not being detected on boot. Only Windows is detected. To access Ubuntu, whenever I boot the system, I need to: (1) enter the boot menu, (2) change the mode to legacy, and (3) type a bit of scary commands in grub then Ubuntu successfully opens. This is a bit of problem for me. So I wanted to know the solution for this problem. So please kindly look over my problem as soon as possible.

• How do I modify these VPN connection settings for Xfce?

  - by Dave M G

  I have signed up for a VPN (Virtual Private Network) service, and I configured it for use on my computer that runs Gnome Classic with the following instructions: In Terminal, install openvpn packages with sudo apt-get install network-manager-openvpn. 1. Restart the network manager with sudo restart network-manager 2. Run sudo wget https://www.xxxxxxx.com/ovpnconfigure.zip 3. Extract the files from the zip with unzip ovpnconfigure.zip. 4. Move cert.crt to /etc/openvpn 5. Open the Network Manager on the menu bar. 6. Choose add and select the OpenVPN connection type, and click Create. 7. Enter Private Internet Access SSL for the Connection Name. 8. Enter xxxxxx.xxxxxxxx.com for the Gateway 9. Select Password and enter your login credentials. 10. Browse and select the CA Certificate we saved in Step 3. 11. Choose Advanced and enable LZO Compression. 12. Apply and exit. 13. Connect using the Network Manager. It worked, but now I want to set up access to the same VPN service on another machine that runs Mythbuntu, which uses Xfce as its desktop manager. So every point from 5 on doesn't apply. How can I modify the above instructions so that I can get my VPN service working with Xfce. As a further note, while I can access the Xfce desktop directly if I need to, it's more convenient for me to access it via the command line and SSH from on of my other computers. A command line process would be ideal. (I looked for this, and found instructions only for PPTP access, whereas I need OpenVPN.)

• I cannot remove/install software some dependency issue?

  - by Ryuzaki

  I'm having difficulty trying to install/uninstall applications in Ubuntu 12.04 LTS. I have this warning error that appears on my desktop in the form of a red icon with a line through it and it states: An error occurred, please run Package Manager from the right-click menu or apt-get in a terminal to see what is wrong. The error message was: 'Error: BrokenCount 0' — This usually means that your installed packages have unmet dependencies. I tried to repair automatically through ubuntu software center and I kept getting errors or it just didn't seem to work. Afterwards, I opened terminal and used sudo apt-get check command to see what the problem was and the results yielded: Reading package lists...

• Dependencies not met on 12.04?

  - by Mochan

  Now I'm very aware that there are many questions out there that are quite similar to what I'm experiencing, but I have looked through many and I have not found a suitable answer. You are welcome to suggest questions that are similar, but I doubt that it will help. Getting on to the issue at hand, whenever I do anything that involves installation, whether it be codecs for videos, new programs or whatever the latter, I always get the 'Dependencies not met' error. In addition, I also get this notification in the panel: When clicked, the menu says this: "An error occurred. Please run Package Manager from the right-click menu or run apt-get in a terminal to see what is wrong. The error message was: ' Error: Broken Count 0'. This usually means your installed packages have unmet dependencies." It gives me three items to click: Show Updates Install all updates Check for Updates And then finally: Show Notifications (with a tick) Preferences When I try 'Install all Updates' (also Check Updates Install) it says this: and also this: As well as 'Ubuntu has experienced an internal error' and 'Did this error occur when moving from one version of Ubuntu to another?' (I clicked NO, because it didn't). So I took it's advice and ran sudo apt-get install -f This is what results: Reading package lists... Done Building dependency tree Reading state information... Done Correcting dependencies... Done The following extra packages will be installed: libapt-pkg4.12:i386 The following packages will be upgraded: libapt-pkg4.12:i386 1 upgraded, 0 newly installed, 0 to remove and 87 not upgraded. 1 not fully installed or removed. Need to get 0 B/941 kB of archives. After this operation, 0 B of additional disk space will be used. Do you want to continue [Y/n]? Y E: Internal Error, No file name for libapt-pkg4.12 When running sudo apt-get update it's all fine, but running sudo apt-get install -f still results in the same thing. I really have no idea what to do... can anyone help me?

• external display in Ubuntu 13.04

  - by thuc2009

  I have had a look on series of similar topics but I could not find a right answer. Currently, I bought laptop Dell latitude E6530 and installed Ubuntu 13.04 (64 bit) alongside with Windows 7 (I could not get rid of it because of some special programs for work). Ubuntu worked well, however, it did not detect the external displays (Dell 23" and Dell 19") no matter I plugged them before or after booting. Edited: I connected my laptop to those external displays through a laptop dock. I went to Settings- Display, the displays were there, but when I enabled them, Ubuntu logged off automatically. No external display was detected. In addition, the laptop screen sometimes was detected as Dell 23" I got an advice from similar topic that nvidia driver should be updated to version 313 or 319. I upgraded driver and the unity launcher disappeared, main display resolution turned to 640*480 and none of external displays was detected. I tried to use additional drivers, but when I turned it on, it told me that there was no driver to be used. Could some one tell me what should I do ? Edited : options vmwgfx enable_fbdev=1

• How to reset Compiz/Unity to defaults?

  - by Stramato

  I tried to activate some compiz effect via ccsm (I think wobbly windows) and compiz crashed and froze up the screen. So I used the Control+Alt+Backspace keystroke to force logout. Then I logged back in. Unity wasn't there, just a (non-unity) panel at the top with file, edit, and the like. I was able to pull up a terminal and launch ccsm, only to find almost all settings wiped out. I turned everything back on that I thought should be on, but I don't know if I got everything. Also, now whenever I open up a non-maximized window, it opens up in the top left corner with the title bar behind the unity panel. So what I need is a list of everything that needs to be on in ccsm, and a way to get windows to NOT open in the corner, preferably without having to reset unity or compiz.

• 14.04 default locales

  - by Seán Ó Séaghdha

  After a new install of 14.04 I have quite a few extra locales/languages. Is this normal? I installed using English (GB) I think since en_AU isn't an option. At some point apt offered a list of unused files which I removed. Now when I open Language Support it warns me that "Language support is not installed completely" and offers to reinstall this list... kde-l10n-zhcn thunderbird-locale-en-gb thunderbird-locale-es libreoffice-l10n-en-gb libreoffice-help-es libreoffice-help-en-gb wspanish thunderbird-locale-zh-cn myspell-es ibus-sunpinyin mythes-en-au kde-l10n-es libreoffice-l10n-zh-cn fonts-arphic-uming ibus-table-wubi thunderbird-locale-es-es thunderbird-locale-zh-hans libreoffice-l10n-en-za thunderbird-locale-es-ar hunspell-en-ca libreoffice-l10n-es libreoffice-help-zh-cn kde-l10n-engb fonts-arphic-ukai So are Spanish and Chinese installed by default in all installations now? Why do I need Canadian English spellchecking installed?

• Can't get vnc to connect

  - by Thom

  I have a server and my laptop. I want to be able to start vnc server on the server and then connect from my laptop. Both are running ubuntu 11.10 64 bit desktop On my server, i installed x11vnc. I set it up with a password, no view only password. I ssh to the box and typed vncserver :42 Now on my laptop, I installed gtkvncviewer and ran it. It popped up a box. I entered the picard:42 (the name of the server in my /etc/hosts file) and the password. I tried with and without the user. It always disconnects immediately. Can anyone point out what I'm doing wrong? Is it because I'm not running a GUI session currently on picard? If so, how can I start the Xwindows session remotely to connect with vncserver?

• Upgrade to 11.10 caused rt2800usb module to be blacklisted

  - by Shevek

  I just upgraded from Kubuntu 11.04 to 11.10, and I noticed that after the upgrade my USB wireless card was no longer recognized. It turns out that the rt2800usb module had been added (automatically, I assume, unless previously the module had been loading despite being blacklisted) to /etc/modprobe.d/blacklist.conf. I re-enabled the wireless card by commenting out the blacklist line and adding rt2800usb to /etc/modules, but I was wondering if there was a reason for rt2800usb being added to the blacklist.
