• Why do I have to add a PPA twice (once to add it to the list of repo, second time to fix a BAD GPG)

  - by Luis Alvarado

  I notice the following: I add a ppa using add-apt-repository, for example the wine ppa, mozilla security, nvidia drivers, etc.. When I go to the Update Manager and tell it to CHECK for updates it throws me a PPA error. To solve the error I add the same PPA again. Why do I have to add the PPA again (This also can be done by adding the received key alone with apt-key) but why does this problem happen anyway.

• Random touchpad and keyboard freezes on new 10.10 installation

  - by ancaleth

  My touchpad and keyboard freeze up on my newly installed Ubuntu 10.10. I was using Ubuntu 10.4 via wubi before on this Laptop where this problem never occurred. (I did not migrate wubi or upgrade to 10.10, it's a fresh start. 64-bit on Dell Studio, plenty of RAM, plenty of free space on partition etc.) I can't say there is a pattern yet, once it happened during the download of packages with the Update Manager, once it was just using Firefox, no other program running. I was forced to shut down manually. In between these crashes the laptop was booted once, updates were installed etc., firefox was used and there weren't any problems. Both crashes should be in the attached kern.log and I noticed there were some error problems before the last crash (at the end, obviously). It seems the wireless was experiencing problems. This wasn't noticed on the user end, since the touchpad + keyboard were already frozen. kern.log: http://paste.ubuntu.com/552617/ How can the freezes be fixed?

• Wow is very faster on GNOME Shell comparing to unity

  - by João Vinholi

  I have been trying to run WoW on ubuntu 12.04. When I run it on unity, the frame rate is very low and it is impossible to play. Although, when I launch it on gnome shell, for some reason, the frame rate gets very high and the playing experience is very comfortable. The problem is that I prefer running unity instead of gnome shell, but I like to play WoW too. Is there a way to run WoW on unity, with no lag?

• Gnome 3 freezes when switching workspaces

  - by Bill Cheatham

  I have found an odd problem with Gnome 3 on Ubuntu recently. Under certain circumstances, when switching between two workspaces the whole desktop and user interface will 'freeze' for anything up to 2 minutes; during this time I cannot click anything or interact using the keyboard. Often, the screen will show a 'half-completed' animation of the workspace swapper. This is on Ubuntu 12.04.1 running on a 2-year old Macbook Pro, and it only seems to occur when using an external monitor. This does not seem to be a processor or memory issue, and does not occur every time I switch workspaces. Is this a known problem? What can I do in the short or long term to fix it?

• Installing Broadcom Wireless Drivers

  I'm having serious problems installing the Broadcom drivers for Ubuntu. It worked perfectly on my previous version, but now, it is impossible. What are the steps to install Broadcom wireless drivers for a BCM43xx card?

• Is ubuntu-geoip (GeoClue) is used for tracking?

  - by tijybba

  I am happily learning Ubuntu more closely now. I came across the process ubuntu-geoip-provider in system monitor. Is is used for tracking or for gathering nearest server info, or for syncing time with Internet, or perhaps for all these things? I searched for it but not enough information came through. If it is tracking, what kind of info it is gathering, and why it is doing that? It is based here: /usr/lib/ubuntu-geoip I just wanted more detailed information for that. Also, can this be disabled? Is disabling recommended, or would doing so cause dependency-related (or other) problems?

• how to modify another user's .profile from the recovery console?

  - by Pinpin

  Pretty much everything is in the title, really! ;) I installed a few components to compile go programs, and the last step was to add the go directory to the path. Being a total ubuntu noob, I added the line PATH="Path/To/Folder", after the one that was already there. After the first reboot I can no longer log into ubuntu (the screen black-out for a while and then I'm back to the login screen, and the same chime greets me.) I've been able to boot in recovery mode, open the root's profile with vi, but I cant find my other user's profile, nor pretty much anything.. Any hint would be greatly appreciated! Pascal

• Windows gets progressively slower over time, why doesn't Ubuntu?

  - by William

  I, and many other previous Windows users notice that the computer seems to get progressively slower over time. I bought a leapfrog crammer only to find it installed process that sat there waiting for me to plug the crammer in so it could run the software. It took up three percent of the CPU twenty-four seven, seven day a week! This is one of the main reasons I left Windows. But, Ubuntu doesn't seem to slow down over time at all. Does Ubuntu allow programs to install background programs like the leapfrog crammer did to sit there like a leech and suck away at resources? Could someone explain why Windows tends to get slower over time, and is Ubuntu vulnrable to this too? Thanks for any help, this is puzzling me.

• HP G42 Ubuntu live cd failure

  - by Jon

  Ok, I have tried every option under the sun. I have surfed through the internet for a good 3 hours straight and to no effect. I installed ubuntu on my HP G42 laptop, it worked fine, then when I tried installing the standard after installation updates my wifi failed. In my attempt to fix my wi-fi I rebooted my laptop, when I rebooted I was stuck on a black screen with nothing that I tried to fix it helping the situation. So I then tried to fix it by reinstalling Ubuntu. When I attempted to boot into the live ccd it failed leaving with the now familar black screen. After numerous attempts using instructions from live cd and instal failure blank screen... page and replacing my hard drive at a cost of $65 I am coming here for help. As for the actual DVD that I tried installing ubuntu from it was able to install ubuntu on a mac just fine after my issues on the HP. After installing the hard drive I loaded up windows just fine but I don't want windows I want ubuntu, can you please provide instructions on how to install ubuntu?

• How to reduce bubble-notification time in empathy?

  - by MCan

  empathy shows a bubble notification message on top right corner if a user comes online or goes offline (obviously we can change them from the preferences), but is there any way we can reduce the time for which the bubble notification remains on screen. By default it remains fro 3-4 seconds, is there any way we can change it to 1 or may be 2 seconds (I know the matter is of few seconds only but 4 seconds looks too long and I want to reduce it). Any help is welcome. Cheers.

• Stuck at boot, both with wubi and USB

  - by Christoffer

  I have tried installing Ubuntu 12.04 through USB and with wubi interface. Nothing works. With USB, I will enter the main menu, doesn't matter what i choose, "install ubuntu on a hard drive" or "boot into ubuntu from USB". When I click on one of those it will scan my drives or something, and when it gets to the USB it gets stuck. It just stays there.... With wubi, the install goes fine, but when trying to boot for the first time to ubuntu it says "completing ubuntu installation"... NOTHING more happens, that cursor only blinks there. How can I get Ubuntu to work??? I got: 1TB HDD, 256GB HDD, 80GB SSD. I'm trying to install Ubuntu on my 256 GB HDD....

• How do I remap the keyboard shortcut for Gnome Do?

  - by johnc

  I am giving Unity a chance to win me over in Natty, but I admit I am a heavy Gnome Do user and Unity has remapped the Super+Space keyboard shortcut to show the Unity Launcher. I am not yet convinced with the new Unity Launcher and would like to keep using Gnome Do, at least until such time as I am convinced that the Unity launcher is as frictionless as Gnome Do. Is it possible to remap it to Gnome Do?

• When running Minecraft with OpenJDK, my keyboard becomes unresponsive?

  - by Mochan

  I recently downloaded Minecraft with the .jar format and had it running on my computer not so long ago. Now that I'm using my desktop instead of laptop temporarily, I want it to run. On my laptop it was a tremendous hassle to get OpenJDK to even run the application without it going black and I don't have that problem on my desktop. However, when I run the application on desktop, my keyboard becomes unresponsive and doesn't type at all. This is a really big problem because I can't play the game as it requires keyboard interaction. It works as normal on my laptop though and it works perfectly. But now on the desktop it's completely useless. I don't know if there's like a keyboard driver I'm missing, but there shouldn't be because the keyboard runs flawlessly everywhere else. I'm using OpenJDK 6 because the 7 has the same 'black screen' I mentioned. So I need this to work within OpenJDK 6. Thanks so much in advance and I'll try to specify as many details as I can.

• How to make backlight work on Acer 5732z?

  - by Dude Random21

  I want to run 12.04 on my Acer Aspire 5732z. I know from research that these computers have issues with the backlight on Ubuntu. So I tried a couple of solutions: The sudo lightdm restart method. I get no change at all. The sudo setpci -s 00:02.0 F4.B=30 method. This so far has been the most effective. I first tried it in the F1 console, right away I get the screen back, problem is going back to the desktop it goes back to being black. So I tried it from a terminal window and it works as well but as soon as I unplug my external monitor the screen turns black again and doesn't come back. If I plug the monitor back in the screen stays black and the only thing I see is the mouse pointer. From here I go back into console (which I am able to see) and reboot from there. The sudo sed -i 's/GRUB_CMDLINE_LINUX=""/GRUB_CMDLINE_LINUX="acpi_osi=Linux"/g /etc/default/grub method. This one I got no instant change and after reboot still no change. I'm open to pretty much any suggestions you may have.

• Ubuntu 12.04 wallpaper problem when using two monitors

  - by jiomsa

  I am using two monitors, the main resolution is 1920x1080 and the secondary is 1440x900. Everything seems to work fine (with default drivers, fglrx crashes bad), besides windows opening in the wrong monitor (even when the main is set correctly), but now what I am trying to fix is the wallpaper problem, here's an image to explain it easier: http://i.imgur.com/msLRR.jpg It also happens with gradients. The secondary monitor is physically aligned like in the image, lower than the other, the wallpaper on the main screen seems to keep the size of the lower resolution, and then it start at the correct resolution the last part at right. Any way to fix this? I am using Ubuntu 12.04 with Gnome-Shell 3.4.1, the vga is a Radeon HD 6950 UPDATE I went to gnome-tweak-tool and disabled "Have file manager handle the desktop", now it looks ok on both monitors, but I can't have icons on my desktop, so I am still interested in solving it. UPDATE2 Disabling "Have file manager handle the desktop", in gnome-tweak-tool and then re-enabling it seems to work, but has to be done every time you turn on the PC.

• Can I use standard tools to get the full name of a process, when its name has embedded spaces?

  - by fred.bear

  I understand that it may be a rare situation for an executable to have spaces in it, but it could happen. An example may be the best explanation.. Using standard tools, I want to determine the location (on the file system) of the executable which owns(?) the current window... get the current window ID ...(xdotool getactivewindow ) use the ID to get the PID ...(wmctrl -p -l | sed ... ID .... use the PID to get the executable's name ... (ps -A ... here is where I run into problems ! Whith ps, when listing only the executable's name (-o ucmd), it truncates the name to 15 characters, so this rules out this option for any name which is longer. Widening the column (-o ucmd:99 ) makes no difference.. If pgrep is anything to go by, its matching is limited to 15 because of stat (see: info pgrep).. Listings in variants of "full" mode (eg -A w w) are not useful when the name concerned has spaces in it, because this name is separated from its args by another space!.. Also, in "full" mode, if the process was started by a link, the name of the link is shown, rather than the executable's name. Is there some way to do this (using standard tools)? ...or are spaces a show stopper here?

• Creating a user called 'root'

  - by pnp

  I am creating Virtual Machines using the ubuntu-vm-builder. The syntax goes something like this: ubuntu-vm-builder kvm precise \ --domain newvm \ --dest newvm \ --arch i386 \ --hostname hostnameformyvm \ --mem 256 \ --user john \ --pass doe \ --ip 192.168.0.12 \ --mask 255.255.255.0 \ --net 192.168.0.0 \ --bcast 192.168.0.255 \ --gw 192.168.0.1 \ --dns 192.168.0.1 \ --mirror http://archive.localubuntumirror.net/ubuntu \ --components main,universe \ --addpkg acpid \ --addpkg vim \ --addpkg openssh-server \ --addpkg avahi-daemon \ --libvirt qemu:///system ; I need to enable the 'root' user account after creating each of my VMs (and supply a password for it). I was just wondering whether I can take this short-cut of supplying the username (--user) as root in this command itself. If I supply username as root to create my VMs, am I creating/enabling the root user, or just creating a user named as root? p.s.: any better ways to achieve my task are also welcome. But I don't want to manually meddle with each VM after its creation

• GRUB not showing /dev/sda2 is Windows 7 Loader

  - by Ricardo

  A few days ago I accidentally deleted Ubuntu partition using GParted. I thought Windows 7 would start normally, but I got a "grub-rescue" screen instead. Then, I recreated a partition for Ubuntu (/dev/sda6) and reinstalled it. Ubuntu starts properly now; but GRUB shows me /dev/sda2 is Windows Recovery System (WRS), what is false, since /dev/sda1 is WRS and /dev/sda2 is Windows 7 Loader. I booted using Windows 7 disk and tried to correct this problem automatically and by bootrec.exe /fixboot and /fixmbr, and nothing is able to fix my problem. Yet, Windows (disk) says there is no OS in my computer. What should I do? Will I have to erase my hard disk to get Windows 7 back?

• How do I suppress the "New release '12.10' available" message?

Run 'do-release-upgrade' to upgrade to it. Last login: <redacted> $ But I don't intend to upgrade to 12.10, because Mythbuntu recommends using LTS releases only. How do I suppress the "New release '12.10' available" message? I don't want to be notified until the next LTS release is available. I've already gone to Update Manager Settings Updates and selected "Notify me of a new Ubuntu version: For long-term support versions", but that didn't get rid of this message.
