• Starting a guest session from the login screen

  - by Odd-rationale

  I was wondering what is the best way to start the guest session from the login screen (GDM). Currently, I created a new user called 'ubuntu-guest' (has to be something other than 'guest'). Then added the following script to the Startup Applications. #!/bin/bash /usr/share/gdm/guest-session/guest-session-launch & /usr/bin/gnome-session-save --logout The problem with this method, is that when you log in as 'ubuntu-guest', you have to start up two gnome sessions: one for 'ubuntu-guest' and one for the actual guest account. Please let me know if you have any other better ideas. Thanks!

• Skype, green screen, no microphone

  - by EddyThe B

  I have issues with skype using my brand new System 76 Galago Ultrapro, running Ubuntu 13.04. I installed Skype through ubuntu software centre (after allowing Canonical partner stuff), but it won't work, the video is a green screen, and it won't connect to the microphone. The webcam works when using Cheese, and the microphone appears to work in general (it shows sound levels when I go to the Input tab under the Sound settings). I tried to fix the green screen issue using this command: $ echo -e '#!bin/bash n LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so /usr/bin/skype' | sudo tee /usr/local/bin/skype sudo chmod a+x /usr/local/bin/skype as suggested here: http://debianhelp.wordpress.com/2012/09/28/to-do-list-after-installing-ubuntu-13-04-aka-raring-ringtail-operating-system/ but no luck. Any ideas? I have also asked this question to the System 76 tech support folk.

• Lynx "Alert!: Unable to connect to remote host."

  - by Deepend

  I'm pretty new to Ubuntu server. I'm running Distributor ID: Ubuntu Description: Ubuntu 12.04.4 LTS Release: 12.04 I have installed Lynx via sudo apt-get install lynx everything installed fine but when I try to connect to a website it just seems to time out. When I run lynx google.com it goes to a blank screen with a blue line at the bottom. There is yellow text on the line which says "Making HTTP connection to google.com" but it just sits there. Eventually after 5 - 6 minutes it just goes back to the normal terminal window If I run the below on its own lynx I get the same blue line with the same text "Making HTTP connection to google.com" but after 30 seconds or so it briefly turns to a red line with "alert!: lynx unable to connect to remote host" written on it. I have installed lynx locally and it works fine. Does anyone have any ideas?

• How safe is GParted when resizing Linux and Windows partitions?

  - by Olivier Pons

  I want to resize my partitions: I have 3 partitions: Ubuntu 10.04 Windows Seven Ubuntu 11.10 It's booting with the boot installed by the Ubuntu 11.10 version. I want to expand (only expand) all the 3 partitions. My HD is 1,8 Tb so it's big and I have no possibility to save before expanding. So my question is: if you tell me GParted work 99,99 % of the time, I'm willing to take the risk. If you tell me GParted work 90 % of the time, I won't take that risk.

• Incorrect instructions on Upgrading to 12.10 from 12.04LTS

  - by Russ F

  https://wiki.ubuntu.com/QuantalQuetzal/TechnicalOverview/Beta1 reports incorrect instructions for upgrading from Ubuntu 12.04 LTS. The correct steps are: Alt+F2, Update Manager, choose settings, updates tab and set notify to "For any new version." Close the manager. Press Alt+F2, Terminal, then enter "sudo update-manager -d" (without the quotes)... Sorry to pester this list, but the Ubuntu wiki has no provisions for "Talk" or "Discussion" that do not require registration and a login. I feel like I should be able to point out a problem without signing in.

• Pulseaudio no sound card detected. Dummy output only

  - by Zach Smith

  I'm using 12.10 Quantal with Openbox and a .xinitrc script at login instead of a display manager. Its a relatively fresh install and I noticed when I opened pavucontrol the only output was a dummy one. I check around and it appears that my soundcard is physically installed but Pulseaudio isn't detecting it. I'm really unsure what I should do but any help getting my audio back would be appreciated. Edit: further info if its at all useful: dante@dante-ubuntu:~$ uname -a && aplay -l && cat /proc/asound/version && head -n 1 /proc/asound/card*/codec#* Linux dante-ubuntu 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:31:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux aplay: device_list:252: no soundcards found...

• how to get adobe flash fullscreen video fluid with an atom processor?

  - by Antoine Rodriguez

  My system has an atom N270 + intel i915 graphic card. Under Windows I can enjoy 720p bigbuckbunny youtube video fullscreen without any trouble. Under Ubuntu 12.04 I have laggy and choppy fullscreen video and choppy video when not fullscreen. I've seen that under ubuntu the cpu is almost always at 100% use. What I must do in order to have videos playing well under ubuntu ? I've already tried the following : Force flash gpu detection : (no result) : mkdir /etc/adobe echo "OverrideGPUValidation = 1" | sudo tee -a /etc/adobe/mms.cfg grub options (had results but not enough) : i915_enable_rc6=1 i915_enable_fbc=1 i915_lvds_downclock=1 pcie_aspm=force updated intel drivers (glasen ppa) Using chrome instead of firefox (had impact but not enough)

• Creating a spin from my installation

  - by LinuxPCplus

  Over the last 6 months or so I have tweaked & customized my Ubuntu installation until I have what I feel is a perfect Distro! Now I would like to turn it into a custom Ubuntu spin that can be run either as I live DVD/USB or installed to a users HDD. Is there an "easy" way to do this? I would want to use the standard Ubuntu installer but the distro would have it's own name, so I may need to customize the installer to reflect this.

• Graphics Driver problem, ATI Radeon HD 3200, small screen size and slows everything down.

  - by Arvind Jangid

  Regards. I am using a: 2009 Compaq Presario CQ40-415AU Notebook AMD Athlon X2 Dual core Processor 2.1 GHz 1024 MB L2 cache 3GB DDR2 RAM ATI Radeon + HD 3200 Graphics 256 MB, screen is 14 inch widescreen with resolution of 1280*800. I installed Ubuntu 12.04 LTS 32bit on my laptop. It works brilliantly until I installed graphics driver. When I installed the driver, the graphics became slow. Everything slowed down. Even the splash screen resolution changed to something like 640*480. I have liked Ubuntu since 9.10 and for the freedom it provides and its versatility, but graphics problem remains the same. I even installed Ubuntu on a 50 GB partition with 6 GB swap partition. My HDD is 320 GB. Please tell me what is wrong.

• Flash animations doesn't work

  - by sosen

  I have a following problem: I have Ubuntu 12.04 installed on my Athlon 1800+ + 1 GB RAM + Nvidia Geforce4 MMX 440 (pretty old configuration) and everything works just fine except Flash Player in my Web browser (tried Firefox and Chromium). Instead of movie/animation, I get blank space. I updated my system via update manager, checked the plugins (everything OK), installed and updated flash player one more time, installed Ubuntu restricted extras, tried Firefox's Flash Aid, even tried Youtube Html 5 (still the same result)... Please, help me! I enjoy working with Linux and Ubuntu is the first that works for me well (after Open Suse and Fedora) but I have no idea what is wrong now...

• Have I fixed my partition problem with os x 10.5.8? Are my GPT and MBR back to normal?

  - by David Schaap

  I'm new to linux and I have overstepped by abilities. I tried dual booting os x 10.5.8 with ubuntu 11.10 with rEFIt, but I been having problems with partitioning. Instead of enduring more headaches, I've made the decision to simply use ubuntu on VirtualBox. I've tried to return my HDD to normal, but I am looking for confirmation that my partitions are ok. Here is the report from partition inspector: *** Report for internal hard disk *** Current GPT partition table: # Start LBA End LBA Type 1 409640 233917359 Mac OS X HFS+ Current MBR partition table: # A Start LBA End LBA Type 1 1 234441647 ee EFI Protective MBR contents: Boot Code: GRUB Partition at LBA 409640: Boot Code: None File System: HFS Extended (HFS+) Listed in GPT as partition 1, type Mac OS X HFS+ Also, my HDD directory has a bunch of extra folders in them and they appear to be ubuntu related, although it is no longer installed. folders like bin, sbin, cores, var, user, and so on. Those folders aren't supposed to be there, right? Thanks in advance.

• Run virtualbox in other X session

  - by Valicek1

  I'm running ubuntu on my laptop (host). Inside ubuntu, there is running one instance of virtualbox. (where is installed MS Windows). My idea is to run virtualbox in separate X session (something like multiuser). If it is not clear, i'll try to explain... When I want to visit tty1, I'll press CTRL+ALT+F1. To return to my Unity desktop, I'm gona use CTRL+ALT+F7... And here comes what I need. After pressing CTRL+ALT+F8 show fullscreen virtualbox windows system, just to switch as ttys.. I am using Ubuntu 14.10. I have wasted hours by using google to find some solution, but my biggest prolem is I cannot name the problem.

• Will an Atheros AR928X work with WPA2?

  - by Tommy

  Basically I need only the answer to above question. Please think of that I am new to linux. For further explanation here is the full story: I have the following problem. My friends notebook (Vista) has got a trojan and refuses to work anymore. The Avira Rescue CD did not help either. So I tried an old (9.1) Ubuntu CD and backed up all the essential files. Since we have no Windows Install Disk we want to put Ubuntu on that notebook. But with the 9.1 version there is no WLAN. Systemtest tells me, that it finds an Atheros AR928X, but ifconfig does not show that and the network manager tells me there are no LAN/WLAN devices. So: does that work easier with the new Ubuntu version or is that network adapter a known troublemaker? And: if I get the adapter to work, will it work with the WPA2-network around here?

• Battery management doesn't recognize removal of power supply

  - by Jason

  I have a Lenovo Y460p running Ubuntu 12.04 (64-bit). The battery does charge normally, but unplugging the power supply only very briefly shows the correct battery indicator. After about 1 second, it reverts to the charging indicator. If the power supply is connected the power statistics show: "Supply Yes" "Online Yes" If it is not connected it shows: "Supply Yes" "Online No" My problem is almost exactly like the one in this post: Ubuntu 11.10 power management does not recognize removal of power supply The only exception is that my system does not dual-boot with Windows. This is Ubuntu only. The computer in the other post is a Lenovo as well; not sure if that has anything to do with it. Any help would be greatly appreciated. Thanks.

• How to unhide an application?

  - by blacklaptop

  I hope you can help me. I have installed ubuntu 12.04 using wubi, my issue is i installed iptux using ubuntu software center, it worked fine, i decided that i wanted it to be hidden at start up, so i changed its setting in preferences. i assumed that if i needed to use it i could go to internet menu and select it. But after restarting i found that after i click on iptux under Internet nothing happens, but i click it after that then a small window shows Fatal Error!! Failed to bind the TCP/UDP port(2425)! Address already in use. I have tried uninstalling using ubuntu software center and reinstalling it but it still had the same problem. I thought it maybe because some files were not uninstalled by USC, so i installed synaptic and uninstalled iptux (complete uninstallation) and then reinstalled it and the same situation occurs. I was hoping someone could inform me how i could unhide iptux. Thank You

• Out Of disk, but still boots

  - by LinuxPCplus

  I have a HP Compaq nx6310 notebook wth 4gb memory & a new 250gb hdd. After installing Ubuntu 12.04, i got an "out of disk" error & was unable to boot. I rebooted in live, instaled & ran Boot Repair then rebooted. Grub menu loaded fine, followed by "out of disk.....press any key to continue". I pressed a key & Ubuntu booted, a bit slow but still booted. So here are my questions: 1- Since Ubuntu DOES boot, should I just leave it alone? 2- If I need to fix this, HOW do I do it? 3- What causes this error? $wolf@lpc-1:~$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 230G 9.1G 209G 5% / udev 1.6G 12K 1.6G 1% /dev tmpfs 655M 868K 654M 1% /run none 5.0M 0 5.0M 0% /run/lock none 1.6G 260K 1.6G 1% /run/shm wolf@lpc-1:~$

• Samsung NP305U1A laptop won't resume from suspension

  - by Oskar Pålsson

  I just bought a Samsung NP305U1A laptop and installed Ubuntu Desktop 12.04 LTS on it. Whenever I suspend the computer and try to wake it back up, the monitor only shows a black screen and the only thing I can do is a hard reset. Kernel: 3.2.0-24-generic Graphic: Radeon HD 6320 Anybody know what to do? UPDATE I did some some research and remebered that I installed the "ATI/AMD proprietary FGLRX graphics driver" from the "Additional drivers" software bundled in Ubuntu. I also tried to install the "ATI/AMD proprietary FGLRX graphics driver (post-release updates)" but whenever I do, it gives me an error and I can't continue So I decided to make a clean install of Ubuntu 12.04 again and when i tried the suspension out-of-the-box, it did work. But since I can't install the drivers I need, HD video is choppy like hell. So perhaps the suspension bug was fixed in the post-release updates of the driver, but sadly I cannot install them, and I don't know why.

• GNOME lock screen (screensaver) is missing music controls

  - by oleg

  I have a custom Ubuntu 12.10 configuration (started out as a minimal installation of Ubuntu 12.04 with a number of other packages such as Gnome Shell selectively installed via apt-get and then upgraded to 12.10). (Almost) everything works just fine. However, the lock screen (Gnome screensaver) does not expose a UI to control music playback. Whenever I have Rhythmbox running in the background I cannot pause music playback without unlocking the screen. Obviously some package(s) or configuration bits are not present but I am not able to figure out what needs to be added or done in order to enable playback control in the lock screen. Any idea what I might be missing? Ideally I would not like to install Ubuntu desktop only to get music controls in the Gnome lock screen.

• Just updated, after reboot my computer won't start up again

  - by Alex

  I have a macbook that I use on occasion which dual boots Ubuntu and OSX (It has rEFIt installed). I turned it on for the first time in a while and it needed a bunch of updates. So I let it run, and restarted it when it asked. When it was booting up, it got stuck at a light blue screen. There was nothing on the screen to indicate that it was doing anything - I figured it just got stuck or something, so I turned it off and back on. (I suspect now it was actually working, but I had no indication that it hadn't just frozen) Now I can't access either OSX or my Ubuntu partition. When I choose ubuntu on the rEFIt menu, it shows "No bootable device -- insert book disk and press key". If I try to start up OSX is looks like it starts loading, but instead of an apple logo there's a crossed out circle icon.
