• USB Wifi that works with 12.04

  - by Colin Matheson

  I have done several hours of searching and I am still looking for a few USB wifi adaptors that run in 12.04 with no additional driver installations or other fiddling. I am looking to plug in the adaptor and have the laptop recognize and start connecting. We have 30 older laptops with flaky internal wifi cards so I thought that if I could find a $10-$20 USB adaptor that work reliably in 12.04 I could plug it in and solve all my connectivity problems for a few hundred dollars.

• "Pointers" with $ Syntax in /etc/environment

• VNC grey screen and start on boot 12.04

  - by Siriss

  I have 12.04 LTS installed and I am trying to get VNC to work. I want to be able to connect to existing sessions, and have it start on boot.

• gnome-shell, gnome 3, unity, cinnamon, mate confusion

  - by Bryan

  I am thinking about adding something besides unity into my ubuntu 12.04. My questions are this: -If I add cinnamon, mate, gnome2/3, could I still call it it Ubuntu, or would it be Mint? -Why not just add Mint instead of cinnamon, or mate, into Ubuntu? -Or is Mint just those at the core, and not the other way around? -I had terrible battery drain using Mint. Something was wrong with the kernel with my laptop type. If I add cinnamon, would I get that battery drain again? -And lastly, would I be able to get that awesome HUD if I add the other things? I realize these questions are a bit confusing, or at least they are for me.

• MAAS and Openstack Network

  - by user281985

  Trying to figure out the best way for openstack and MASS networks to co-exist. Assuming MAAS used 10.0.0.0/24 for provisioning of various openstack nodes, once openstack, with quantum, is deployed should 10.0.0.0 be used as management network, external network, both or discarded? Reason for the question being that I ran a deployment where openstack used 10.0.0.0 as its management network, MAAS dhcp and dns were active; however, I could only access VMs through namespace and was not able to utilize MAAS's dhcp to assign floating IP. (VMs network was through an internal bridge 10.10.10.10, and external bridge was using the same interface as MAAS.) Any thoughts or ideas are appreciated.

• Bazaar - pull the last revision only (and not the whole branch)

  - by Sandman4

  Shortly: How can I take the latest revision (only) from a remote bazaar repository and add it as a new revision to a local repository. Background: I have a development system and a production system. On a development system there's a bazaar repository having branch with lots of development revisions. Once in a while I want to incorporate the latest developments into production system. I want to do so by some sort of "pulling" (development system can not connect to production for security reasons, but production can initiate connection to development). On the production, I don't want the whole development revision history, only those revisions which actually go into production (normally it's the branch tip). Yet I want version control on the production system to keep track of what actually goes into production each time. bzr pull pulls the whole branch. bzr pull --revision=last:1 also pulls the whole branch, up to the specified revision. bzr merge --pull --revision=last:1 also pulls the whole branch. bzr merge --pull --revision=last:2..last:1 and bzr merge --pull --change=last:1 both pull only the new changes introduced in the latest revision, but not changes introduced in the older revisions. With lightweight checkout I have no track of revisions which are pulled into production - local working tree remains part of the remote repository The only way I see so far is importing the working tree using some rsync or scp and committing them to a local branch afterwards. Any better ideas ?

• Where to install boot loader on a Zenbook Prime?

  - by Christians

  I cannot figure out where to install the boot loader on my Zenbook UX31A Prime. I have installed Ubuntu many times on normal hard drives, but this is the first SSD and I am struggling. Installed Ubuntu 12.04 64-bit selecting "UEFI: general" boot entry. Installation type: Something Else Created partition /sda5 mount as /, /sda6 mount as /home, /sda7 mount as swap Selected /dev/sda for boot loader installation. Other options are /dev/sda, /dev/sda1/dev/sda3 Windows 7 (loader) ... Grub comes up with 6 entries Ubuntu - this runs great Linux 3.2.0-29-generic recovery mode: mode hangs with "fb: conflicting fb hw usae interdrnfb vs EFI VGA - removing generic adapter" memtest86:erro: unknown command `linux 16' memtest86 serial: unknown command `linux 16' Windows 7 (loader) (on /dev/sda3): invalid EFI file path Windows Recovery Environment (on /dev/sda8): unknown command drivemap, invalid EFI file path. My workaround for booting Windows 7 is hitting ESC during boot, windows boot manager comes up and * for booting into Windows 7 I select "WIndows Boot Manager (PO: SanDisk ....". * for booting into Ubuntu I select ubuntu (P0: SanDisk...) How can I boot into Windows from Grub?

• How to clean and add options to the Open With list of apps

  - by Luis Alvarado

  After installing several PPAs (Wine, PoL) and opening several files with other apps (Like changing from Totem to VLC) I discovered that the Open With option had 2 problems: Many items on the list are duplicated (As seen on the image for "A Wine Program") Sometimes the app I want to use to open is not shown there (For example, Virtualbox or VLC) So how can I edit this list to clean the duplicates and add missing apps from the list.

• My ASUS U32U with fresh Xubuntu install shows a black screen 50-80% of the startups

  - by Jona Ekenberg

  I have recently installed Ubuntu 12.10 with Xubuntu-package on my ASUS U32U notebook (Radeon HD 6320 GPU). The issue I have is that more often than not, after the GRUB-select screen I get a black screen, and three times total white lines (kind of) flashes very quickly (with maybe 5 seconds between each flash). I'm not even able to get to the login-screen (nor the Xubuntu loading screen). At first I thought it was simply me having installed something dumb or messed up some settings, but even after reformatting the partition and installing ubuntu again, the problem remains. Before I formatted it xfce4's window manager wouldn't start either, but it does now (when I am able to see anything). I can access the virual consoles (ctrl+alt+f1), but I can't see anything, but I've managed to shutdown the computer by using it (sudo shutdown -h now).

• Is there a way to group 2 or 3 gui windows so that they don't get lost behind other open windows?

  - by Gonzalo

  For instance floating panels and main window in Gimp are independent windows. If I change focus to a full window (e.g. Firefox by doing Alt-Shift) and go back to the main Gimp window I don't get back the floating panels also (I have to change to them as well in order to see them). It would be great if the 3 windows can be "tied" (or linked) together in order that they don't get lost behind other open windows when I change back to (make active window) any of them? I think this configuration (if it exists) should show itself more obviously in the gnome environment. This question seems to address the same problem but it doesn't seem to be accurately answered.

• No windows whatsoever after compiz reset

  - by Shashank Singh

  Currently using 12.04. This time I was trying to use the application switcher, and it asked me to resolve a few conflicts most of which were not easy to comprehend. So after some yes and no dialogue boxes leading me nowhere, I thought a reset should set things fine. However, after preferences-reset to default, I can't see any window!! NONE whatsoever except the log out one when I press ctrl+alt+del All I can see is the wallpaper and the mouse pointer. I cant even see the terminal or anything when I press alt+f2. I am posting this when I switch to ubuntu 2d (I cant make out the difference between the two, but this just works for now almost the same way)

• Icon zoom on gnome panel with mouseover?

  - by brent.with.a.mustache

  I'm actually quite surprised that I couldn't find any information regarding this question through simple google-ing; I would think that it was something of a no-brainer kind of question. I'm basically trying to figure out if there's any way to have the icons in the side panel/favorites bar magnify as you mouseover them, much like you'd see in any the popular launcher programs (i.e. rocket dock or apple's launcher)? I'm on a netbook with a rather limited amount of screen real estate to work with, so the icons depicting my "favorite applications" have been reduced to a permanent, unsatisfying handful of pixels. Again, it seems to me that this should be a fairly obvious feature to include in the options for the panel, so I'm hoping that there's an easy solution. Unfortunately, I haven't found any way to make this happen, so any help would be appreciated. Here's a screenshot :squint: http://i.imgur.com/OpMIF.jpg -- ubuntu 11.10; gnome 3; hp mini 110

• Ubuntu gone out of order - Wont install any packages. What do I do?

  - by Aborted

  Lately, I've been getting some strange behaviour from Ubuntu. First and the most important is that it wont install updates. It gives a package installation error and it simply wont work. Earlier I tried to install TeamViewer via the Software Center, but got the same package error. I also feel like the connection speed is going slower than it should - don't know if this one is relevant to this case. What's wrong with my installation? How do I fix these package installation errors?

• How to import a pdf in libreoffice? under ubuntu, all pages are blank

  - by Daniele

  I have some .pdf generated by a scanner, that I want to import in LibreOffice and do some small editing. The PDF has only one object per page, a page-size image. If I open it in LibreOffice under Ubuntu 12.10, it imports "successfully" but all pages are blank. I have the libreoffice-pdfimport package installed. That is true with both LibreOffice 3.6 (part of Ubuntu 12.10) and with 4.0.2, from libreoffice ppa. The same .pdf files open perfectly fine on both LibreOffice for Windows and LibreOffice for Mac (yes, I have three computers with all three OSes), but on Ubuntu 12.10, all pages are blank, so I can only conclude this is an issue with Ubuntu packaging, or something really weird prevents it from working under linux. How can I import these kinds of .pdf into LibreOffice for editing?

• Ubuntu 12.04 freezes on suspend hp folio 13

  - by Tom O'Brien

  I have ubuntu 12.04 running from a usb HDD on my hp folio 13. Everything is working, but at first the screen would only blacken when i closed the lid and didn't suspend. So, I followed this guide: https://github.com/deliciousrobots/ubuntu-hp-folio-13 after that, it sort of worked, but very unreliably. Now suspend doesn't even work and it always freeze. Usually the screen will turn black but I can still see my mouse. Sometimes my desktop background will show but the launcher wont be there or anything. Once I didn't have the menu bar on any windows or the top of the screen but the windows I had left open were still (sort of) responsive. Whats wrong? Help Thanks

• print jobs are held until the VirtualBox guest OS is reboot

  - by broiyan

  Here is the setup: VirtualBox 4.1.20 (which the Help window describes as 4.1.12_Ubuntu) Extension Pack 4.1.20 (for USB support) Windows 7 Home Premium as a guest operating system on VirtualBox Ubuntu 12.04 with dist-upgrade's to September 2012 as the host operating system. Fuji Xerox DocuPrint P205b, which I believe is a GDI printer, connected via USB. The problem is that often print jobs will sit in the print queue and nothing comes out of the printer. The printer status for the first item in the queue will be Printing even though nothing happens. Then upon rebooting Windows, the print jobs get printed, seemingly simultaneous to the rebooting process; that is as Windows reloads. One way to avoid this problem is to reboot Windows with the printer cable attached, and then submit the print jobs. The print jobs get printed in a timely manner. Perhaps VirtualBox has a problem with USB being plug-n-play and hot pluggable. It's not convenient to have the printer plugged in when Windows boots because: One, this is a laptop, and Two, I may be boot Windows for a purpose other than printing and not anticipate needing to print. Are there any recommendable fixes for this problem?

• Java 1.7 update 07 and Google Chrome

  - by Peter

  I've just updated Java from 1.6 to 1.7 via the Software Centre - removing the old Java 1.6 and selecting the new Java 1.7. Firefox works fine. But when I use Google Chrome to access a Java test website it says the Plugin is out of date. I click on run anyway and it says that it's running version 1.7. I've cleared Chrome's Cache and Plugin data and this hasn't changed anything. Anyway ideas? (Ps. It's Ubuntu 12.04 64 bit)
