• What commands are needed to install Ubuntu Core?

  - by Oxwivi

  Ubuntu Core's wiki page page contains the instructions to install Ubuntu Core on a target media: Uncompress (do not unpack) rootfs Format target media: at least one partition should be ext2, ext3, or ext4 Unpack Ubuntu Core to ext{2,3,4} partition Install boot-loader Install Linux If the Linux kernel requires modules, add these to /lib/modules/$(uname -r) in the ext{2,3,4} file system Boot the target device Install any additional required software using apt-get But what are the specific commands to do the above? The things I'm specifically confused about are: Uncompressing and unpacking, what's the difference and how do I do them? What package should I install if I want the generic kernel provided in regular Ubuntu installation? I won't be installing any drivers or anything related to kernel other than what's provided in the repos, do I need to worry about manually adding kernel modules? PS I would like to request that all the commands used in the installation process be mentioned in the answer, for the benefit of ones who're completely unfamiliar and myself, should I ever forget.

• Ubuntu 11.04 and 10.04 hang with black screen while installing from USB disk

  - by Bill

  I've been trying to install Ubuntu 11.04 from a USB flash stick and each time I try to boot from the USB key one of two things happen: A) The screen that asks you what you would like to do (e.g. run Ubuntu from the USB key or install it) shows up and the countdown to the default option starts to count down but as soon as I either touch the keyboard (sometimes I press enter or the arrow keys to select an option) or the countdown gets to zero the screen just locks up and nothing happens no matter how long I wait. B) When I boot from the USB key the screen will flicker for a second and then go black with a flashing white underscore at the top left corner of the screen. Again it doesn't matter how long I wait, nothing happens and pressing keys doesn't do a thing. The very first time I tried to install it I got a terminal-like screen that said something about a directory called 'casper' having an error of some sort. I have tried installing from USB using both 11.04 and 10.10. I'm about to try 10.04. I have read tons of forum posts about this but so far I haven't seen anything in the solutions that apply to me. My intention is to dual boot Windows 7 and Ubuntu. I must keep Windows as I am required to use Visual Studio for one of my college courses. Right now I'm using Wubi but I really want a full install. I can't use LVPM because it doesn't work with the version of Wubi I used. So now I'm thinking my best bet is to try to get a clean install working. I'd also convert Wubi to a full install too but there's no solution as far as I've read. So could someone tell me a reason why this is happening or if there's something I can do to get around the problem? I'm using a Gateway LT2802u netbook with and Intel Atom N455 processor, 1GB RAM, Intel Graphics Media Accelerator 3150 graphics card, and a 250GB HDD. I don't have anything on my current Wubi install that I can't replace so keep in mind when answering that I don't care if I lose my current settings and files from Wubi. Thanks everyone! UPDATE I just answered my own question so in case anyone else is having this same problem using similar hardware, do the following: When I first tried installing 11.04 I used the recommended universal installer tool to create the USB live/installation disk. That caused the original problem. Note that I had already downloaded the 11.04 ISO and did not use the included downloader from the USB creator. After that failed I used the same USB creator but had it download 10.10 for me. It also failed with the same issue. I repeated this process with unetbootin as well for both versions. Finally, I downloaded the Ubuntu 10.04 ISO and used the recommended USB creator once again. There was an error while creating the USB live install so I reformatted the USB key as FAT32 and tried again. It created the USB key. I then booted from the USB flash drive and selected "Install Ubuntu" (exact wording was different). It worked! It took me through the process that you see shown in pictures on the Ubuntu website. I let it create the appropriate partitions for me and it simply worked. I did get a few errors while the system tried to restart after it installed. It hung on a terminal-like screen but I pressed ENTER and it restarted. I booted into Windows 7, it checked the disks as it sensed that I messed with a partition, then it booted into Windows normally. Now I'm going to uninstall Wubi and update my new full install of Ubuntu! I'm excited to get the benefits of a full install now. So in the end, hopefully someone can learn from what I did.

• Ubuntu One Sync for multiple folders, not just the Ubuntu One folder.

  - by bisi

  Hello, I may have misunderstood Ubuntu One as a service, but this is how I had pictured it. At home, I tagged a few folders with the "Sync to Ubuntu One" tick and it started uploading. Now back at work, on Win7, I installed Ubuntu One and thought I was going to be able to tick which of the backed-up folders I could download/sync to this machine. From what I gather after a little research is that whatever I would like to synchronize would need to be in the Ubuntu One folder? There is no way to do this outside of that? Thanks for confirming, or informing me whether this will be introduced in the future as an option? Thank you very much for your help on this! bisi

• ubuntu one syncronizing problems

  - by user72249

  I am a user of Ubuntu and Ubuntu One. First: I had a serious problem with ubuntu one. I have a windows and several Ubuntu machine and they all sync one account. My first problem is that i can't really delete files. Whenever I delete something Ubu One resync it, so it appears again in my folder. Furthermore, when i move something to another dir it synconize the new location and resync the old one, so i got doubled my files. I can't reorganize my files. So i tried to delete the duplicated files through the web dash, but i cant reorder and select multiple files by extension. For example i wanted to move all PDF to another location... Second: I can't configure in the ubuntu one app the loacation of the main One folder. For example i want my One folder to be on another partition than my HOME folder. It is a main problem in linux and windows also. I tried to move that folder in windows with the hardlink method. So i uninstalled the U1, then i created a folder link to another drive, than installed the U1. THEN i lost all my files in my U1. Lucky thing that i have a backup, but i thought U1 is a stable solution for me, and i planned to extend my space, but these bugs are major problems! It's worth to pay for it if it's working perfectly. I think it's more important than releasing a new version in every month.

• Ubuntu boots to totally blank after I installed some graphic card updates

  - by baboonWorksFine

  I am using Ubuntu 10.04 LTS, dual boot with win7 on ThinkPad T400, I followed Ubuntu update hints and installed some update for my ATI Radeon graphic card, but when I boot to Ubuntu(means I can still load GRUB), the tragedy happened, the screen goes to blank and no matter what key stroke, I can not get any responds, I try to go to text terminal, but impossible! However when I hit the power button, the computer would pop out the Ubuntu shutdown screen briefly and shut down. I figure out I should delete the updates package of my graphic card, but I don't even get a chance to go to text terminal, please help me!

• Ubuntu One downloads already existing files

  - by Islam Hassan

  I've uploaded some files to Ubuntu One from my home laptop and begin to download it on my work laptop. Then I've got a USB and copied these files directly through the USB driver. My problem now is that Ubuntu One still downloading these files although I've copied them to Ubuntu One folder. I need it to consider the already existing files as synced and don't download it again. And I need Ubuntu One for further use so I can't simply quit it. How could I mark the already existing files as synced ?

• How to reset settings when Unity won't finish booting?

  - by Emre

  I have a new 12.04 installation and I messed things up after trying to move /home to an NTFS partition, which I later learned was a bad idea. I removed references to the NTFS partition on fstab and created new users on the ext4 / partition. Now I can't get Unity to start up properly for any user. I get the GUI with only three Launch icons (none of which are clickable) and no bar at the top. The keyboard seems to the nonfunctional after I enter my credentials. The interesting thing is that I can boot when I go through recovery mode and select resume. I wonder whether I am creating the new users properly. What is the correct protocol for doing so in order to ensure that they can run Unity?

• Installed nvidia driver, activated it, and now Unity is gone. No bars, menus, nothing

  - by Noel

  I installed the nvidia driver (installed the ubuntu-x-swat ones, updated them, got the updates for them, installed bumblebee. I restarted everytime I did those steps, so no, i don't simply need to 'restart X'. I tried to run things using bumblebee, but bumblebee was like "can't access GPU driver". So I ran nvidia-settings, it said the drivers weren't in use, so I ran "sudo nvidia-xconfig", then restarted. Now, my login screen looks differently than it did before: it asks me if I want to load: "GNOME, GNOME - no effects, Cairo Dock - GNOME, System Default, or Ubuntu" when I log in, but WORST OF ALL: i no longer have any kind of GNOME/unity GUI. There are no title bars above any windows, no close/minimize/maximize buttons. The unity bar is gone, and will not show up when I call it. And the top status bar is also no longer there.

• How can I edit/create new launcher items in Unity by hand?

  - by Ike

  Will Unity allow making custom launcher icons from .desktop files or via menu editing system? (Right now the launcher doesn't give the option to "keep in launcher" on all programs. For some programs I use, I have to make custom launchers or .desktop files. For instance, daily blender builds are generally just folders with an executable. In basic gnome or kde, I can make a new menu entry with the menu editing system. Then, I can also add it to docky either from the menu or by dragging a .desktop file to it. Unity launcher doesn't support drag and drop, so thats not a bug or anything, but when i open a .desktop file, it has unpredictable results. Most time it will not have"keep in launcher". Sometime it will have a pinnable item without the .desktop's icon, and if i pin the item to the launcher, it will not call upon the program again after closing it. I've also gotten it to just work with a .desktop file for "celtx".

• Will Unity allow users to change the color/appearance of the top-Panel?

  - by Sam

  I'm very excited by the functional design principles and keyboard shortcuts that are being implemented for Unity. And function of use is more important to me than looks. However, after experiencing the aesthetic beauty of the display of the top panel in gnome-shell, I was wondering if users would be able to alter the color of Unity's top panel? IMHO it does not look as good as the gnome-shell implementation (or mac OS X/iPad). I think if an alternate color/appearance were chosen for the panel, it would make a big difference aesthetically. Is there a way to make it Black like gnome-shell? Or are the color choices limited to theme-designs as pointed out in this answer? For efficiency and clarity, the Panel should be better differentiated from application controls. The panel should be a different color because it has a "constant (always present) state," unlike application controls. For contrast and easy-recognition, I would like to make the Panel black (like gnome-shell) but make the application controls (e.g., those of Firefox) "Inverted"

• Ubuntu 13.10 - Black screen after login session

  - by AlexKibo88

  Yesterday, the system asked me if I wanted to upgrade to 13.10 from 13.04. Since that was the first time for me, I decided to proceed and ran the installation without worrying about it. After the system completed the upgrade, my PC was rebooted and the new version of Ubuntu signalled that the desktop would have run in low graphigs mode due to a graphical driver problem. I couldn't manage to fix the issue, so I continued with the low graphics mode... but nothing showed up. I wasn't even able to access one of the TTYs. So I ended up rebooting the system and accessing the recovery mode. I uninstalled all my ATI graphics drivers along with xorg-server and fglrx. After rebooting, I was able to access the login session of Ubuntu, but after confirming my credentials, the desktop wouldn't show up, but instead a black screen appeared with the following message: System program problem detected I couldn't figure out the problem and tried to restore/re-install all the graphics elements I knew. but nothing worked. The screen still remains black and won't show the icons nor the Unity bar. What would you advise me to do? Should I try launching a fresh install of the OS from the live CD? Thank you.

• Updates broke my themes/shell [Ubuntu 12.04 running Gnome 3 ]

  - by APNW

  I am running gnome-session 3.4.2.1. After the latest updates (listed below) my theme regressed to what looks like tango - not sure. Am unable to change it using Gnome-tweak tool or the display settings. I am also unable to change the wallpaper. Here's what it looks like: Synaptic: Chromium and this is the wallpaper page even though I have selected the wallpaper, it actually does not change. This same problem occurred on my personal computer, and one other computer I have, all running the same software/config. The interesting thing is that while Gnome 3 and Unity are affected, Cinnamon is not. What I've done so far: purged and re-installed both gnome 3 and Unity- no change noted. So, how do I fix this? Thanks Here's the installation log: Start-Date: 2013-11-07 12:01:28 Upgrade: chromium-browser-l10n:i386 (28.0.1500.71-0ubuntu1.12.04.1, 30.0.1599.114-0ubuntu0.12.04.3), libswscale2:i386 (0.8.6-0ubuntu0.12.04.1, 0.8.8-0ubuntu0.12.04.1), chromium-codecs-ffmpeg:i386 (28.0.1500.71-0ubuntu1.12.04.1, 30.0.1599.114-0ubuntu0.12.04.3), chromium-browser:i386 (28.0.1500.71-0ubuntu1.12.04.1, 30.0.1599.114-0ubuntu0.12.04.3), libpostproc52:i386 (0.8.6-0ubuntu0.12.04.1, 0.8.8-0ubuntu0.12.04.1), libavcodec-extra-53:i386 (0.8.6ubuntu0.12.04.1, 0.8.8ubuntu0.12.04.1), libavformat53:i386 (0.8.6-0ubuntu0.12.04.1, 0.8.8-0ubuntu0.12.04.1), libavutil-extra-51:i386 (0.8.6ubuntu0.12.04.1, 0.8.8ubuntu0.12.04.1) End-Date: 2013-11-07 12:02:00 Start-Date: 2013-11-07 17:32:55 Commandline: aptdaemon role='role-commit-packages' sender=':1.136' Install: libmusicbrainz5-0:i386 (5.0.1-2~precise2), udisks2:i386 (1.98.0-1~precise1), libclutter-gst-1.0-0:i386 (1.5.4-0ubuntu2), libudisks2-0:i386 (1.98.0-1~precise1), cinnamon-session-common:i386 (2.0.4-20131105043005-precise), librhythmbox-core6:i386 (2.97-1ubuntu1~precise1), gcr:i386 (3.4.1-3~precise1), libcluttergesture-0.0.2-0:i386 (0.0.2.1-2ubuntu3), libmx-1.0-2:i386 (1.4.3-0ubuntu1), guile-2.0-libs:i386 (2.0.5+1-1), libclutter-imcontext-0.1-0:i386 (0.1.4-2build1), libnatpmp1:i386 (20110808-3ubuntu1) Upgrade: gnome-keyring:i386 (3.2.2-2ubuntu4.1, 3.4.1-4ubuntu1~precise1), cinnamon:i386 (2.0.6-20131026040307-precise, 2.0.10-20131105040309-precise), gir1.2-muffin-3.0:i386 (2.0.3-20131023003029-precise, 2.0.3-20131105003012-precise), gir1.2-totem-1.0:i386 (3.0.1-0ubuntu21.1, 3.4.3-0ubuntu1~precise1), nemo:i386 (2.0.2-20131023010018-precise, 2.0.5-20131105010007-precise), aisleriot:i386 (3.2.3.2-0ubuntu1, 3.4.1-1~precise1), procps:i386 (3.2.8-11ubuntu6.2, 3.2.8-11ubuntu6.3), libcinnamon-desktop0:i386 (2.0.2-20131025011504-precise, 2.0.3-20131105011505-precise), libgck-1-0:i386 (3.2.2-2ubuntu4.1, 3.4.1-3~precise1), totem-plugins:i386 (3.0.1-0ubuntu21.1, 3.4.3-0ubuntu1~precise1), cinnamon-desktop-data:i386 (2.0.2-20131025011504-precise, 2.0.3-20131105011505-precise), rhythmbox:i386 (2.96-0ubuntu4.3, 2.97-1ubuntu1~precise1), libgcr-3-1:i386 (3.2.2-2ubuntu4.1, 3.4.1-3~precise1), seahorse:i386 (3.2.2-0ubuntu2.1, 3.4.1-2~precise1), muffin-common:i386 (2.0.3-20131023003029-precise, 2.0.3-20131105003012-precise), totem-common:i386 (3.0.1-0ubuntu21.1, 3.4.3-0ubuntu1~precise1), libtotem0:i386 (3.0.1-0ubuntu21.1, 3.4.3-0ubuntu1~precise1), rhythmbox-data:i386 (2.96-0ubuntu4.3, 2.97-1ubuntu1~precise1), gir1.2-cinnamondesktop-3.0:i386 (2.0.2-20131025011504-precise, 2.0.3-20131105011505-precise), cinnamon-session:i386 (2.0.1-20131021043004-precise, 2.0.4-20131105043005-precise), rhythmbox-mozilla:i386 (2.96-0ubuntu4.3, 2.97-1ubuntu1~precise1), rhythmbox-plugin-zeitgeist:i386 (2.96-0ubuntu4.3, 2.97-1ubuntu1~precise1), libmuffin0:i386 (2.0.3-20131023003029-precise, 2.0.3-20131105003012-precise), cjs:i386 (2.0.0-20131021020602-precise, 2.0.0-20131105020703-precise), rhythmbox-plugin-cdrecorder:i386 (2.96-0ubuntu4.3, 2.97-1ubuntu1~precise1), cinnamon-common:i386 (2.0.6-20131026040307-precise, 2.0.10-20131105040309-precise), gnome-disk-utility:i386 (3.0.2-2ubuntu7, 3.4.1-0ubuntu1~precise1), nemo-fileroller:i386 (2.0.0-20131021020004-precise, 2.0.0-20131105020003-precise), libnemo-extension1:i386 (2.0.2-20131023010018-precise, 2.0.5-20131105010007-precise), rhythmbox-plugins:i386 (2.96-0ubuntu4.3, 2.97-1ubuntu1~precise1), gimp:i386 (2.8.6-0precise1~ppa, 2.8.8-0precise0~ppa), cinnamon-settings-daemon:i386 (2.0.5-20131026004504-precise, 2.0.6-20131105004505-precise), libgimp2.0:i386 (2.8.6-0precise1~ppa, 2.8.8-0precise0~ppa), gir1.2-rb-3.0:i386 (2.96-0ubuntu4.3, 2.97-1ubuntu1~precise1), wpasupplicant:i386 (0.7.3-6ubuntu2.1, 0.7.3-6ubuntu2.2), libcjs0c:i386 (2.0.0-20131021020602-precise, 2.0.0-20131105020703-precise), nemo-data:i386 (2.0.2-20131023010018-precise, 2.0.5-20131105010007-precise), totem:i386 (3.0.1-0ubuntu21.1, 3.4.3-0ubuntu1~precise1), gimp-data:i386 (2.8.6-0precise1~ppa, 2.8.8-0precise0~ppa), transmission-common:i386 (2.51-0ubuntu1.3, 2.73-0ubuntu1~precise1), cinnamon-translations:i386 (2.0.1-20131021040407-precise, 2.0.1-20131105040807-precise), totem-mozilla:i386 (3.0.1-0ubuntu21.1, 3.4.3-0ubuntu1~precise1), rhythmbox-plugin-magnatune:i386 (2.96-0ubuntu4.3, 2.97-1ubuntu1~precise1), transmission-gtk:i386 (2.51-0ubuntu1.3, 2.73-0ubuntu1~precise1) End-Date: 2013-11-07 17:34:40

• Ubuntu slow on HP 2000 notebook with Apu e1-1200

  - by user169861

  I am using HP 2000 notebook which initially came with Windows 7 64bit. It has 4gb ram, AMD APU E1-1200 (1.4ghz) with Radeon 7310. With Windows it worked ok, so I decided to switch to Ubuntu. I installed 13.04 64bit at first, but responsiveness wasn't that good (opening windows, menus, Firefox, dash search) even if it was way better during the testing from live USB. I tried different kind of drivers for graphic card, 13.6beta, 13.4, fgrlx proprietary, upgraded kernel but the situation was the same. Then I tried installing 32bit version but the results were identical. After that I tried LTS version 12.04 and Xubuntu 13.04.. Responsiveness wasn't that different at all. Not sure what to do, and I wouldn't want to go back to Windows. This machine is not a beast, but it should be enough to deal with Unity or Xfce without troubles. Oh yes, I have insydeH20 BIOS with not so many options at my disposal. Thanks and best regards,

• Ubuntu 13.10 AMD/ATI proprietary driver slow boot time, lengthy login/logout delays

  - by NahsiN

  Ubuntu 13.10 is causing me major headaches with my AMD/ATI HD 5770 GPU. Below is a list of problems I am currently encountering. 1) The boot time is extended by at least 25s after installing catalyst 13.4. Using open source radeon drivers, my boot time till the login screen is ~10s. With catalyst 13.4 installed, the boot time increases to ~35s. This was not the case in Ubuntu 13.04, 12.10 or 12.04. I have done the driver installation manually (instructions from wiki.cchtml.com) and using software center and there is no difference. I have not tried the catalyst 13.8 beta driver. 2) After manual installation of catalyst 13.4, I get stuck at a black screen after logging in. I have to purge fglrx to resolve the problem. I tried sudo amdconfig --initial -f but it didn't help. 3) The delay between logging in and unity being displayed is ~10-15s for BOTH open source and proprietary drivers. During the delay, it's just a black screen. Whenever I logout, there is again a ~10-15s delay with the login screen appearing stuck before lightdm allows me to enter my password again. This is ridiculous! Yes, I could stick with open source radeon drivers but I would like to install Steam and play my Valve collection on the machine. Is anybody else encountering similar issues?

Sometime it will have a pinnable item without the .desktop's icon, and if i pin the item to the launcher, it will not call upon the program again after closing it. I've also gotten it to just work with a .desktop file for "celtx".

• Ubuntu always freezes on a friend's machine

  - by missingfaktor

  I am posting this on my friend's behalf. I installed Ubuntu 12.04 on my friend's computer but it continuously froze, no desktop effects worked, and it was frankly unusable. I thought this might be an issue with Unity and how it interacts with his hardware, so I tried several other desktop environments on his machine. These include KDE, Xfce, and GNOME. The problems persisted regardless of the desktop environment. I would like to note that he dual boots his system with Windows 7. Even there no desktop effects work but the system is reasonably stable. The following screenshots describe some of his system information (He is running Xfce at this time): 1: 2: Card information: intel corporation 82G33/G31 integrated graphics controller (rev02). What is the issue and how can it be solved? Please let me know if I should add any more information. Thank you.

• How to chroot Ubuntu+1?

  - by jrg

  What is the recommended way to use chroot from Ubuntu Stable (in my case 11.04) with Ubuntu+1 (11.10)? Linked (but probably separate) is "Is there anything special that I need to do in order to get Xorg working?" Reason I ask is because I'd like to test a few GTK3 programs without losing my current (stable) Ubuntu, or having to get my data synced. I thought about maybe running a SSH server from 11.10 and then using SSH's X forwarding, but that seems rather cumbersome.

• Ubuntu 11.10 UI changed suddenly?

  - by VeeKay

  10 64 bit on a Dell laptop that has 6GB RAM and 1GB graphic card. All of a sudden there were some sudden changes in UI which I am unable to understand why. The unity panel was initially glassy and transparent, now it looks all black in its background. Likewise the alt+tab graphics was working well until it got changed suddenly and now shows icons on pure white background. I've not tried to install any themes and I've not tried to tweak anything. Why did this UI changes occur? Could it be that it is unable to detect the graphic card or something? How can I fix this and how can I get back the original desktop back? Please help..

• How to get the Dash and HUD to appear. (and stop Unity spewing error messages.)

  - by Ubuntiac

  I just installed Ubuntu 12.04 on my wifes Dell Inspiron 1501, which uses an R300 ATI graphics chip. Neither the Dash or HUD appear when pushing the appropriate key. When I try unity --reset & in the terminal, I see that over and over it's spitting out: r300: CS space validation failed. (not enough memory?) Skipping rendering. This is just after starting Ubuntu with no apps open, so I find it hard to believe that just rendering the Dash / HUD is completely blowing out the VRAM. Any suggestions on getting this working? /usr/lib/nux/unity_support_test -p shows OpenGL vendor string: X.Org R300 Project OpenGL renderer string: Gallium 0.4 on ATI RS480 OpenGL version string: 2.1 Mesa 8.0.2 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes All sections say "YES"

• hotkeys do not work sometimes in ubuntu 12.04

  - by stepank

  I use Ubuntu 12.04 with Unity 2D and I've stumbled upon this issue: sometimes shortcut keys stop working in some windows. For instance, I have these windows opened usually: Google Chrome, Terminal, Skype, Pidgin. Sometimes everything is OK and shortcuts work no matter what window I hit them from, however, hotkeys hit from Skype (more often) or Pidgin (less often) do not work, but they still work from Terminal or Google Chrome. Moreover, not all hotkeys are affected, the problem holds only for locking the computer (Ctrl + Alt + L) and other custom shortcuts like executing some command or launching a program (I used zenity --entry with [Super | Ctrl] + [some letter: K, N, etc] for testing). Does anyone have a clue what is causing the problem and how to fix it?

• Large uploaded file won't display in Ubuntu One but is included in file usage

  - by user1488963

  On Ubuntu 10.04, I uploaded a single 711 MB. My total file usage in Ubuntu One went up to 877MB, which is about right, but the file doesn't show in Ubuntu One so I can't download or delete it. Either the file is there and I can't see it for some reason. Or the file is not there and the total file usage figure is wrong. Does anyone know what has happened? I have a free account but am well below my 5GB limit.
