  • T420 Triple Head with Optimus

    - by Rolo
    I see that this is possible on a T520 apparently (Triple-head on a Lenovo T520), but I can't see anyone claiming it's possible on a T420. I'm running 12.04 and have Bumbleebee installed and working fine but I can't get the display port monitor to display anything. The power light flicks on, but things only render on my VGA output monitor, and Ubuntu's display settings don't detect the third monitor. I'm not concerned with power management, ie, am happy to leave set on discrete graphics in the BIOS if that helps. Is this possible? Thanks.

  • Setup suspend-on-lid-close/Fn+F4 outside of KDE/Gnome?

    - by maxschlepzig
    On current Ubuntu (10.04) suspend-on-lid/Fn+F4 only works if some powermanagement-applet of KDE/gnome is running. But what about suspend-to-lid if you are working on the console or using a non-bloated window-manager? What is the current mechanism to configure suspend-on-lid system wide? What of hald/udev/acpid/foo-kit/random-thing is the right place to hook this feature in? What is the up-to-date command to suspend from the command line/script? echo -n mem > /sys/power/state pm-suspend pmi or something else? Btw, if it matters, I want to configure it on some Thinkpads.

  • broadcom 43225 wireless on acer laptop is disabled

    - by Robbie
    I have a acer aspire 5820T with a broadcom 43225 wireless card. I previously used ubuntu 10.10 and the wireless worked straight away, but when I updated to 11.04 the wireless stopped working. I have managed to get the wireless hardware to switch on for a couple of seconds before turning off (When you turn the wireless on using the manual switch the wireless light stays on for a couple of seconds and in the drop down connections menu the information under wireless networks changes from 'device not ready' to 'Disconnected' but shows no wireless networks despite there being one). So far I have tried installing an additional driver, and also disabling the additional driver and installing b43-fwcutter and firmware b43 installer. There may have been other things that I've found in searches that i've tried but unfortunately I can't remember them. Any help would be appreciated.

  • thunderbird-bin causing CPU (core) lockup (12.04, 64bit, up-to-date)

    - by david6
    I have experienced 2-3 unexplained lockup over last 10 days. Today, I had a random lockup (no mouse, keyboard response, 100% CPU). But, when I finally switched (Ctrl-Alt-F1) to command line (it took several minutes) it told me that thunderbird-bin had locked a CPU. I ran this to resolve: pidof thunderbird-bin sudo kill #### However, after saving other work, I tried restarting Thunderbird. It went to 90%+ CPU, and within 20 seconds it locked again. Once I have more detail I will raise a bug (on Ubuntu Forums). Does anyone have any other suggestions, advice?

  • Can't mount external hard drive

    - by tezza
    i have a problem accessing the data on my external hard drive. I recently did a fresh install but mistakenly left my external hard drive plugged in. When I tried to access the data on the external HDD, it says "no files" but recognizes that there is 290 GiB of data on it. The HDD is 350GB big. I checked the drive with Disk Utility and it showed that the hard drive had a bootable flag. So, in the edit partition, I unchecked this bootablity. Now it won't mount in Ubuntu and now my XP can't recognize it at all, whereas I could access the data on the XP machine before. In disk utility, it doesn't give me the option to check the bootable box in again and I can't access the data on XP either. Any ideas on how to fix it?

  • Update to Grub2.x broke Xubuntu 12.04 client in VirtualBox

    - by mikodo
    I have VirtualBox-4.1 installed in Ubuntu 10.04 with a .vdi running Xubuntu 12.04. Recently, a Grub update for Xubuntu 12.04 to Grub2.x, broke it with the following explanation: error: ELF header smaller than expected grub rescue _ Is there an easy fix for this? I could reinstall, but I tweaked Xubuntu 12.04 to my liking, and don't want to re-install a new .vdi. Unfortunately, I didn't make a snapshot of it. Google results, have been over my head. Thanks.

  • About partition sizes

    - by Lassi
    I am going to install Ubuntu on a new computer, but I'm not quite sure how big each partition should be. If I create only root, home and swap partitions, on what partition will programs be installed? Will they go to /home or to root? Basically does it make sense for instance to have following partitions: / - 6GB /home - 80GB /swap - 4GB Is 6GB large enough for my root partition? Also are these 3 partitions a good choice, or is there a better configuration? I have at the moment 3 operating systems installed, and I do make changes quite often.

    - by gotqn
    Possible Duplicate: Screenshot of active window doesn’t work I am using Ubuntu 12.04 and I am searching for a program that will let me to do screenshot of my menus too. Also, it will be very useful if I am able to "cut" only part of the new screenshot and save it as a new image.

This happens to with applications launchers menus in the left navigation panel. On windows I am using Gadwin Pro. Is there any alternative on Linux?

  • Creating a new DHCP lease databse

    - by Stee1bear
    I have Ubuntu Server set up as my DCHP server. We have had it install for a few year and our dchp.lease file contain over 4000 entries. I am wanting to clean it up and basically start a new lease file to get current list (@1500 entries). I have read the walk through on how to make a new lease file and get it started, which leads me to this question. Will the dhcp server try to give each unit new IP address or will it build the new database with the IP addresses that the the units report to it?

  • How do I make Unity quit opening Firefox under the Shiretoko icon?

    - by Azendale
    I'm using Ubuntu 12.04, and whenever I open Firefox, whether it is from searching on the dash or clicking a 'quick-launch' launcher, it always opens yet another icon for the running instance that is a blank page and says Shiretoko. It will pulse the Firefox icon for a while (I'm guessing until a timeout or something). It's as if Unity no longer recognizes the Firefox process as Firefox and misidentifies it as Shiretoko. (I know Shiretoko was a testing version of Firefox a long time ago.) How do I set Unity straight? I imagine that it has something to do with me once using Shiretoko, but I believe that was even on a different installation, just the same home folder. Is there some place Unity caches this information that I can clear (or remove specific parts of)?

  • How to get rid of bookmarks in synced Chromium

    - by Lambda Dusk
    I'm using three Ubuntu systems in an irregular pattern, and since I use Chrome/Chromium anyway and have a Google account, I decided to make my life a bit easier and sync them. Now I am having a problem: When I want to remove bookmarks from my lists, they not only come back when I switch the machine, they double. By now, I have up to ten identical bookmarks in the list and I spend a lot of time scrolling over them. Is there any way to remove them permanently? EDIT: Apps, too.

  • How Can I Upgrade to 11.10 from the Command Line?

    - by nmagerko
    I am trying to upgrade my 11.04 Ubuntu operating system to 11.10, as the current system is not the most recent. However, I cannot use the GUI to upgrade - as from past experience I have learned this - because my graphics hardware only works on 10.04 to 11.04 (non-inclusive) and from 11.10+. So once I can get to 11.10, I should be just fine. Because of this, I need to find a way to upgrade the OS from the command line. Can this be done? Thanks for any and all help.

  • Logitech K260 keyboard responds very, very slow

    - by Pierre
    I bought a Logitech K260 wireless keyboard/mouse combination and connected it to my Ubuntu 12.04 workstation. The mouse seems to work fine for now, it is quick and is working quite smoothly. The keyboard however is very, very slow. It takes about two to three seconds for a character to appear after being typed. What might be the problem? I have found even a review of someone who states that he's gaming with this keyboard, which I am not planning to do, for me it will serve as a writing keyboard only as soon as it works properly. Who might be able to help?

  • How to change the default desktop environment?

    - by Kshitiz Sharma
    I wanted to try out different desktop environments so I installed XFCE, KDE, GNOME, etc on top of Unity in Ubuntu 12.04 After a while I decided that I didn't like those other DEs and would stick to Unity. So I changed my default DE to Unity by configuring gdm. > sudo dpkg-reconfigure gdm Now I am able to choose my DE at login time and all of DEs are working properly. But the strange thing is that my boot up screen says 'lubuntu', my login screen is KDE, and my desktop is Unity. How and why is this happening? Why didn't my gdm configuration have any effect? Does login and boot up screen need to be configured separately from the DE? There are other similar questions here but they are not the same as this one. I do not want to remove the other enviroments I'm quite happy with having a list of DEs to select from. I want to know how to set proper defaults.

  • Energy saving with two batteries (Gigabyte S1080 and similar)

    - by user37155
    my today question is: how do I manage a tablet (Gigabyte 1080) with an additional battery in Ubuntu ? The control bar shows two separate batteries but starts to suck all the energy from the secundary battery, not leaving any power in it and ruining it (if I don't remove it earlier), and then starts with the primary battery. Here you find a description of the secundary battery: http://www.gigabyte.com/products/product-page.aspx?pid=3837#kf Do you have some solutions for a more confortable use of te device, with windows-like drivers maybe ? Is there a graphical tool to manage two batteries in Linux, in order not to ruin them, and possibly to save energy with them ? Many thanks and greetings, Francesco

  • Is it possible to power down my external via the eject button?

    - by beanaroo
    I'm trying to convert from Windows 7 to Ubuntu 12.10 with Gnome 3.6. Using the notification area's eject icon, I notice the partition is unmounted but the drive is still powered and spinning... I understand the latter can be taken care of by means of udisks --detach /dev/sdb I really don't want to have to run a command everytime I eject. Windows does the whole process when ejecting a medium via the systray. Is there a way I could add in the command to the eject button? Is there an appropriate place I could file a feature request? Little things like this are making it hard for me to swap back over to Linux. Thanks for the support!

  • Reduce boot time between grub menu and login screen

    - by Sudheer
    I use Ubuntu 14.04 LTS version which used to boot fast at beginning but not i loads very slow. I searched for this but can't find suitable answers. so i want to reduce my boot time which is now around 1min 12sec (boot chart) overall but i noticed its taking a longtime after grub menu and before login screen. A Blank screen appears after grub waiting... then login screen appears. I want to know a way to reduce that blank screen time(or if possible remove) and get login screen as fast as possible. I already removed several of my startup applications. Getting desktop after log-in is fast. I don't want to remove unity and install light desktop envinorments like Xfce and Lxde. Here is my boot-chart image Thanks in advance

  • Unity-2D ALT F1,F2 custom configuration

    - by LGB
    I have been using Ubuntu since the first public version (I used Debian before). I always have had the policy to change between 8 workspaces with ALT F1...F8. I know this is not a "standard" or so, but I prefer this. It worked well with Unity (Unity-2D, I mean) too, after some configuration. But currently the odd thing happened that after a system restart this is not the case anymore, I am totally lost what could happened. Now ALT F3...F8 works, but not ALT-F1...F2, which just focuses launcher/dash, which is not the thing I want. I know this is the standard meaning of these key combinations (AFAIK) but defining my own key combinations worked before and now it stopped working ... If someone have any idea how to restore my custom configured meaning for ALT F1...F2 too, please share with me. Thanks!

  • Window controls missing; Cannot maximise or minimize applications

    - by omg_scout
    Ubuntu 12.10 32 bits, fresh installation. How can I make Unity maximize or minimize a window? I see no button,option, anything, do I miss something big? Quick googling did not give me a piece of answer, too: On first screen, I have a terminal window. Only clue about maximizing it I found was pressing F11 which made it fullscreen, hiding left bar as well. I would prefer it to take whole free space instead of whole screen. How can I do that? On second screen, I have an opera browser which takes bigger part of the screen but I can't make it take whole screen. Restarting opera did not work. How do I minimize/maximize apps? Also, in case I would like to see the desktop, only solution I found was closing everything Help guys. I kind of like new GUI, but I can't have simplest tasks done there, I feel like I miss something big there.

  • LibreOffice Spell Checker doesn't work?

    - by Michael
    I was a little surprised to discover that in LibreOffice (3.5.4.2), the spell check doesn't actually work. I was surprised since spell checkers have been around since....80's? Not a difficult thing. I am running Ubuntu 12.04, on a relatively new install. I haven't done anything to my dictionaries or language files. Under toolsoptionslanguages writing aids, I have the option selected to check as I type and to use the English dictionaries. However, I get no errors when I type spelling mistakes on purpose, and when I run the checker it just says the spell check has completed and closes the window. Is this a bug with Libre? or have I done something wrong?
