• Ubuntu 12.04 Freezes w/ Ethernet Unplugged + Wireless Drops (Acer Aspire 5516)

  - by Grand Master T

  Ubuntu 12.04-12.10 32/64 freezes or won't boot if the Ethernet cable is unplugged and will not hold a wireless connection. Here is my scenario... Laptop: Acer Aspire 5516 Wireless card: Broadcom BCM4312 Ubuntu 12.04 32/64 Issues Unity 3d won't load without the Ethernet cable plugged in. If I let it load with Ethernet plugged in, it will freeze once I disconnect the cable. Unity 2d will load without the Ethernet cable plugged. In Unity 2d, wireless cannot hold a connection. I can connect to a Wireless network, but when I try to use it (i.e. open a browser), it disconnects. I can reconnect by disabling wireless (uncheck Enable Wireless), re-enable wireless, and reconnect. But, it will disconnect again once I start using it. Ubuntu 12.10 Issues Since 12.10 only gives me the option to load 3d (I assume), I experience the same thing as the first issue in 12.04. Attempted Solutions Enable networking/LAN in BIOS Set LAN first in boot priority in BIOS Remove STA wireless driver (bcmwl-kernel-source) and install b43 low power driver (firmware-b43-lpphy-installer). Remove default Network Manager and install Wicd. So far, I have had no luck with fixing this issue. Does anyone have any further suggestions?

• How to fix Fullscreen focus error in Unity?

  - by Vagrant232

  Recently, I've been experiencing an error with programs that have a fullscreen mode with low resolution (80xx600 and below) in Unity. The problem isn't valid in gnomeshell. Whenever I launch an application, unity would enlarge the screen more than it should be and would only show me the upper left corner of the screen (I only see a magnified quarter of the screen). At first I thought that it was an issue related to wine but I later found out that native applications (such as world of goo) are affected as well. Apps that taken on the full screen but have a larger resolution don't face such an issue. Is it possible to get this fixed manually? Or do I have to wait for updates?

• How do I reset the default icons from the desktop icons?

  - by Jens Reubsaet

  I know this question sounds cryptic, but what I mean is this: I set different icons for the 'home' and mounted volumes on the desktop, but I want to revert that action. How do I do that? I already tried to do it from the icon selection dialog by clicking revert, but no effect. How do I restore this? (the desktop icons are from the default GNOME Icon Theme but I have the Faience icon theme: these do not really match up). Thanks in advance! I'm running Ubuntu-GNOME 13.04 64-bit (GNOME 3.8.2) I set the icons by right clicking, clicking the icon and selecting it by the dialog.

• Always on VPN connection

  - by greg

  I have a working VPN connection. Works like a dream. What isn't working though, is the 'Connect Automatically' option in the Network Connections Manager Panel. It never connects automatically, not at boot, and not after disconnect. I'm not quite sure what that option is for. And I'll get disconnected from the VPN with no warning whatsoever. Is there a way to make sure my computer only connects to the internet through a VPN? So that if the VPN connection isn't established, my computer can't reach the internet. And is there a way to get ubuntu to attempt to reconnect to the VPN automatically if for some reason the connection drops?

• Setting to protect gnome-terminal from key logging

  - by yanychar

  Looks like it is easy to log keystrokes of all processes of the same user. A basic keylogger is 'xinput'. xinput test-xi2 The command generates log of all key-presses. Unfortunately, this includes passwords in gnome-terminal. Googling suggested that grabbing keyboard may prevent other windows from capturing key strokes. Is there a way to prevent XI2 logging in gnome-terminal? Or is there an X terminal that has this feature?

• Ubuntu Software Center (10.04LTS) Missing Packages

  - by Chris

  I recently downgraded from 11.10 to 10.04LTS for compatibility and support of specific development tools. The Ubuntu Software center is missing many packages that I had access to in 11.10, most notably LibreOffice. (Also development tools.) Is there a way to update software sources to find the missing packages? (Or are they incompatible with 10.04?) Synaptic does not have libre either. I feel like I am working with a gimped version of USC.

• Ubuntu/Windows XP - Joint systems

  - by Brian Buck

  I have a computer sectioned to run both Ubuntu 10.10 and Windows XP but as XP refuses to log in (If I select XP the log in starts with the Windows logo being shown on the screen for a few seconds before the screen goes blank and the page showing the option of selecting Windows or Ubuntu the re-appears), I would like to clear it completely from the system and just run Ubuntu. Can this be done, and if so, how do I proceed with doing it?

• Why doesn't Ubuntu nvidia-current support the later proprietary drivers for LTS releases?

  - by keepitsimpleengineer

  e.g. in my Lucid 10.04 LTS system I had to uninstall the ubuntu proprietary drivers and manually install drivers from nvidia.com for an upgraded video adapter to get the system to work. This does not seem to be in agreement with MS's policy or with the Ubuntu wiki "nvidia-graphics-drivers" versions published in Ubuntu… Precise (295.20-0ubuntu1): restricted/misc Lucid-updates (195.36.24-0ubuntu1~10.04.1): restricted/misc Oneiric (280.13-0ubuntu6): restricted/misc Natty (270.41.06-0ubuntu1): restricted/misc Maverick (260.19.06-0ubuntu1): restricted/misc Lucid (195.36.15-0ubuntu2): restricted/misc This list seems to be out of date, my maverick system has 295.20-0ubuntu1~maverick~xup1 installed.

• Overlay scrollbars disabled on upgrade - how to reenable?

  - by Aibara Iduas

  When I upgraded from Natty to Oneiric and then immediately to Precise, for some reason the overlay scrollbars stopped appearing. They were enabled and worked just fine in Natty, and are still enabled in theory. I've purged and reinstalled these packages: overlay-scrollbar, liboverlay-scrollbar-0.2-0, and liboverlay-scrollbar3-0.2-0. That did nothing. I also tried using both Ubuntu Tweak and Unsettings, but both showed that overlay scrollbars were turned on (and turning the settings off and back on again did nothing either). Any ideas how to get them back? Thanks!

• How to associate an icon with a shell script?

  - by Peter

  Environment: Ubuntu 11.10 I have a Java application as a jar file. I have created a batch file that contains the following line: java -jar ~/MyApp.jar When I execute this batch file, the Java application works as expected. To create a desktop link, I copied this batch file into my "Desktop" folder. This results in an icon appearing on the desktop. However, the icon shows "Java" on it. I would like to associate a different icon to this desktop link. Would appreciate it if someone can point me in the right direction.

• Additional Drivers error installing in Ubuntu 12.04 (wireless internet and software modem)

  - by gabiro

  I've already search for similar problems but they are so different from mine. these are the drivers http://db.tt/qFZlD5JD I'm having problem with this Additional Drivers once I click the Activate button it will start in downloading and installing but after that it will say Installation failed. Then the "Enable Wireless" will not be available. With the Software Modem issue is the same problem with the Broadcom. These drivers are working on Ubuntu 9 and 11 if I'm not mistaken. Only on 12.04 is not working. One more thing these drivers will enable the Huawei E165g E220. I've already tried other solution for the Huawei to activate but all didn't work. After a restart Enable wireless becomes okay, though. To all Ubuntu experts and masters please I'm begging for help. A million Thank You!.

• How do I enable or disable the global application menu?

  - by Michael Ekstrand

  I'm fairly excited for Unity, as it looks like a promising new direction for Ubuntu. However, I do have a concern - will it be possible to use Unity without the global menu? I have my window manager set to focus-follows-mouse/sloppy focus, and find the productivity gains to be immense. Sloppy focus is incompatible, however, with global menus, as it is possible for the focus to change while you move from window to menu. Will Unity support an option to use window menus while still using Unity?

• How to create shared home directories across multiple computers?

  - by Joe D

  I know there are ways to share a folder across computers making it easy to move files. But I was wondering how one would setup a single login which lets you access the same files regardless of which machine you login on? What I would like is something similar to something you would see in a college campus where students login on machines in the lab and see their files regardless of which machine they use. I know there are server involved here. I have a need to create this on a smaller scale where we have a few computers available (and one of these could act as the server if needed and host the files) that every one shares. Note, the specific install of software might be different on each computer but the login and OS are the same. Since some computers have additional capability that our group members will need to use at rotating schedules (software licenses or hardware components, etc.). I have not done this before, so I would appreciate detailed instructions if possible or a reference to a guide that describes this. Thanks in advance.

• error: you need to load kernel first

  - by Angelos318

  I made a clean install on my Sony Vaio laptop, of Ubuntu 11.10 and when the installation was ready, it prompted to remove the usb I was installing the distro from, and press enter to reboot. After this reboot the first thing I got was the following error: error: couldn't read file error: you need to load the kernel first Press any key to continue.. After that it throws me back to the Grub select screen: Ubuntu, with linux 3.0.0-14-generic-pae recovery mode previous linux versions (none since I made a clean install) memory test If i choose the first option it shows only a black screen and never loads anything. If i reboot the same thing happens. Could I repair this using boot-repair? Is there any other way? Note: I know nothing about linux code so i am a total noob on this one Update: boot-repair did not help Grub.cfg here: http://pastebin.com/GKLuDuhM Boot Info Script: http://pastebin.com/indARkKJ

• Why is Ubuntu One slow to sync in 11.10, either backup or any sub-folder contents?

  - by pst007x

  I have been trying to sync my documents folder of 1.4GB, it still hasn't worked and it has been syncing for a month. The top level syncs, files and folders in the Document folders, but contents of sub-folders just hang. (Gave up and stopped syncing this folder) However,I have tried using the backup facility in 11.10, to backup to Ubuntu One.... I upgraded my HDD space in Ubuntu One. It has been going now for 24hours-ish and only backed up what looks like a couple of percent. (By the way what an excellent idea to backup to Ubuntu One, if only we could get it to actually work! :-o) The odd thing is I can sync to drop box within hours, rather than months. This is bad, and has been an issue since Ubuntu One's release. I have reported this problem and there were promises in later releases this would be fixed, but it hasn't. Canonical cannot help either... I posted on several blogs, a lot of people have the same problem but no fixes. So do I use dropbox or another service, until it is sorted, as Ubuntu does not seem to see this as an issue, I think a fix will be a long time in coming. (However,I love the potential of Ubuntu One and the integration with the OS) Yes my internet speeds are fine, etc... :-) No firewall (sudo ufw status: STATUS: INACTIVE), No Proxy, etc NB: I have raised this as a separate question to others posted here, because my question relates to Ubuntu 11.10, though I have commented elsewhere for help. Plus my question also relates to deja-dup backup to Ubuntu One. Thanks

• Ubuntu 13.10 Security Key

  - by Toby J

  I was attempting to install Ubuntu 13.10 today and it came up with a screen asking for me to setup a security key. In the first place, I'm not sure what a security key is, but It said I would have to enter it everytime I booted Ubuntu so I assume it's the same thing as a logon password in Windows 8. Is there anyway I can bypass this step without setting up a security key or logon password? I hate these things and have always avoided them in Windows. I don't need them as there is never anyone but myself and my wife on our computers. We are retired, no children or nieces, nephews, friends, etc. who ever use our computer and we don't have any security information such as SS #, etc. on it. Also, I quit the installation at this point but I was not seeing any of the screen prompts as listed in the setup instructions on the Ubuntu website. Has the setup for Ubuntu 13.10 changed since these instructions were written? Thanks

• Error: kernel headers not found. (But they are in place)

  - by Guandalino

  I'm trying to install the Guest Additions in VirtualBox 4.04. Host OS is Ubuntu desktop 11.04 64bit, guest OS is Ubuntu server 11.10 64bit. $ sudo ./VBoxLinuxAdditions.run After some output this line is printed: The headers for the current running kernel were not found. But the headers are installed, at least accordingly to dpkg: $ dpkg --get-selections | grep linux-headers linux-headers-3.0.0-12 install linux-headers-3.0.0-12-server install linux-headers-server install The running kernel is: $ uname -a Linux foobar 3.0.0-12-server #20-Ubuntu SMP Fri Oct 7 16:36:30 UTC 2011 x86_64 x86_64 X86_64 GNU/Linux How do I fix things so that Guest Additions installer is able to find kernel headers? Update: added full output. The headers for the current running kernel were not found. If the module compilation fails then this could be the reason. Building the main Guest Additions module ...done. Building the shared folder support module ...fail! (Look at /var/log/vboxadd-install.log to find out what went wrong) Installing the Window System drivers ...fails! (Could not find the X.Org or XFree86 Window System). I don't care for fail #2, because that's a server and I don't need X server. But I need shared folder support. Some further detail: $ tail /val/log/vboxadd-install.log .......... cc1: some warnings being treated as errors make[2]: *** [/tmp/vbox.0/vfsmod.o] Error 1 make[1]: *** [_module_/tmp/vbox.0] Error 2 make: *** [vboxsf] Error 2

• 13.04 gnome problem with drag and drop and text selection

  - by Laurent BERNABE

  I have an ubuntu 13.04 gnome 64 bits, but since a few days I am facing serious problem for doing simple drag an drop : in nautilus, in eclipse, in the browser. Also I can't manage to select text areas with the mouse (the only way I found is to double click on the first word, then expand selection with shift and arrows keys). I noticed that often, after having started a drag n drop, it is cancelled though I did not release the left mouse ! It is as if for each simple mouse clic : two was done ! My graphic card is an ati radeon hd 4330, and I had installed the default purposed driver. I don't know if I should give you results from some terminal commands, as I don't know which could be useful. Thanks in advance.

• Switching from an Ubuntu derivative to original Ubuntu

  - by SteliosSk

  I installed Zorin 6 (based on Ubuntu 12.04), because I like all the whistles it has (plymouth screen,compiz effects,installed codecs, sound themes, etc.). I miss though the modern and futuristic unity environment (launcher, dash, HUD, indicators etc.). Is there a way to switch from Zorin to Ubuntu 12.04.1 LTS and keep all these effects? Or What additional software should I install in an Ubuntu clean install to add the effects Zorin has (plymouth, compiz effects, sounds, audio and video codecs etc.)

• udev rule group ownership not working

• Stuck on busybox after a fresh install

  - by user54841

  I installed 11.10 and was getting stuck on Busybox unless I type exit. After grabbing the latest updates it then didn't get stuck on busybox but instead on a black screen of nothingness. I've now reformatted and started again using the exit technique for the time being. I had a search here before posting and none of the answers gave much insight, other than it 'could be a gfx card driver issue'. I'm using new hardware that has no issues with Mint, Win7 or WinXp. BUT note, I'm not dual booting, its a complete fresh install formatting the entire drive. Any help is appreciated as I'd really like to get stuck into Ubuntu. Thanks in advance. -Luke
