• Can't connect to VPN on Ubuntu 12.04

  - by 12rad

  I'm having a lot of trouble connecting to VPN. This used to work on my machine, but i recently did an update and it's stopped working. I'm not sure what the problem is. My question is how do i debug this? I'm not able to narrow it down to a specific problem. This is what i get when i tail the syslogs. Would appreciate any help!

• Wireless Connected But No Internet Connection (Ubuntu 12.04)

  - by Zxy

  I am using same network for 2 days and everything was normal. However, today even though it shows me as connected to the network, I do not have internet connection. If I use ethernet cable instead of wireless, I am still able to connect to the internet. Also my friends are able to connect to the wireless network and they can get internet connection. I did not update or install anything since yesterday. Therefore I do not have any idea why it is happening. Here is some information about my connection: I will be appreciate to any kind of help. root@ghostrider:/etc/resolvconf# ping 127.0.0.1 PING 127.0.0.1 (127.0.0.1) 56(84) bytes of data. 64 bytes from 127.0.0.1: icmp_req=1 ttl=64 time=0.042 ms 64 bytes from 127.0.0.1: icmp_req=2 ttl=64 time=0.023 ms 64 bytes from 127.0.0.1: icmp_req=3 ttl=64 time=0.036 ms 64 bytes from 127.0.0.1: icmp_req=4 ttl=64 time=0.040 ms ^C --- 127.0.0.1 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 2998ms rtt min/avg/max/mdev = 0.023/0.035/0.042/0.008 ms root@ghostrider:/etc/resolvconf# ping 192.168.1.3 PING 192.168.1.3 (192.168.1.3) 56(84) bytes of data. ^C --- 192.168.1.3 ping statistics --- 19 packets transmitted, 0 received, 100% packet loss, time 18143ms root@ghostrider:/etc/resolvconf# ping 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data. ^C --- 8.8.8.8 ping statistics --- 11 packets transmitted, 0 received, 100% packet loss, time 10079ms root@ghostrider:/etc/resolvconf# cat /etc/lsb-release; uname -a DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION="Ubuntu 12.04 LTS" Linux ghostrider 3.2.0-24-generic-pae #39-Ubuntu SMP Mon May 21 18:54:21 UTC 2012 i686 i686 i386 GNU/Linux root@ghostrider:/etc/resolvconf# lspci -nnk | grep -iA2 net 03:00.0 Ethernet controller [0200]: Atheros Communications Inc.

• Windows doesn't boot after Ubuntu installation

  - by Diogo Garcia

  I have had serious problems installing Ubuntu and Windows and have dual boot. Recently I installed both operating systems, Ubuntu was the last one, and after that my computer was booting directly to Windows 7. I used my Ubuntu USB live to repair the grub, and could repair. Now I initiate my pc with grub 1.99 and Ubuntu and Windows are recognized, but Windows gives an error and don't initiate, suggesting to use Windows DVD to repair the grub. I tried that but with no effects on be behavior. I have a new asus n56vm. This conflicts with gpt and mbr have been a huge pain to me. I don't know what to to, I installed Ubuntu and Windows numerous times since I bought this computer 2 weeks ago.

• How can I fix the "TERM environment variable not set" warning in eclipse

  - by Robert

  I'm running ubuntu 12.04 LTS and working with eclipse (juno) on a c++ project. I keep getting "TERM environment variable not set" in the console while trying to run the program. I realize this means the variable needs to get set. My question is what should it be set to and how do I set it? I've read that it should be 'xterm' in a few places. So I added export TERM=xterm in my .profile and while eclipse stopped giving me the warning, instead it would output unreadable garbage everynow and then (not a side effect of the program). It did display the program output but intermixed were weird characters. This leads me to believe it's not 'xterm' I should be setting TERM to. Or I'm setting it in an incorrect way. Any help is appreciated. Sample output: **TERM environment variable not set.** Please make a selection ----------------------- 1. Create a budget 2. Edit a budget 3. Display a budget 4. Save a budget 5. Load a budget 6. Exit What is your selection: 1 **TERM environment variable not set.** Enter the name of your budget: etc The program continues to execute as expected but the message is highly annoying As someone has commented, I do use system("clear") which is likely the source of the warning? Either way, is this likely just an eclipse issue or something I can fix in ubuntu/linux

• How do I add a custom launcher?

  - by sayth

  I started by searching guides. I found this guide but neither of the main methods works anymore in 11.10. The first solution, I have created the desktop file, however the file location given as .gconf-> desktop-> unity-> launcher -> favourites no longer exists. I can get to /home/sayth/.gconf/desktop but there is no longer a unity folder. The second solution described right-clicking the desktop and creating a launcher. Right-clicking the desktop no longer produces a "create a launcher" option. I manually installed geany 0.21 as the one in the repo's is outdated. It's installed and working correctly, and is executing from /usr/local/bin/geany. How can I add it to the launcher?

• How can I determine which version of FFMPEG comes by default?

  - by Ryan McClure

  I am honestly confused beyond belief about my package that I have installed for FFMPEG. It is, according to Synaptic, version: 4:0.8.1-1really0u1 For some reason, I feel like this is not the version that would come in the repositories and I feel like another PPA that I may have used installed a wrong version. I believe it was the VLC PPA for nightly builds. Can anyone who does not have this PPA on their system tell me what version of FFMPEG they are running?

• Is the difference between sudo and gksu the same as the difference between sudo -i and sudo -s?

  - by fred.bear

  Is the difference between sudo cmd and gksu cmd, the same as the difference between starting a shell with sudo -i and sudo -s? ... or put another way, Is sudo cmd the same as sudo -i cmd and gksu cmd the same as sudo -s cmd? EDIT: Based on what I read on an Ubuntu Documentation Page where it says: You should never use normal sudo to start graphical applications as root. You should use gksudo (kdesudo on Kubuntu) to run such programs. gksudo sets HOME=~root, and copies .Xauthority to a tmp directory. This prevents files in your home directory becoming owned by root. (AFAICT, this is all that's special about the environment of the started process with gksudo vs. sudo). The "AFAICT" doen't really give me full confidence that there is nothing more to it. (..a belated UPDATE: I tested his commemnt today (2 months later) about: "This prevents files in your home directory becoming owned by root." All files I created via sudo/gksu were all owned by "root", and the group was "root".) I've read parts of the info sudo and noticed the -i and -s seem to be doing the same thing as the AFAICT environment issue... but I hit overload.. so I've asked my question here. PS.. My question is not about sudo vs gksu .. It is more about: Is gksu the same as sudo -s .. and if not, how do they differ?

• Stitch scanned images using CLI

  - by Adam Matan

  I have scanned a newspaper article which was larger than the scanner glass. Each page was scanned twice: the top and the bottom parts, where the middle part appeared in both images. Is there a way to quickly match and stitch these scanned images, preferably using CLI? The panorama stitching tools I know require lengthy configuration, which is mostly irrelevant: lens size, focus, angle etc. Hugin has a solution for this issue, but it isn't practical for batch jobs.

• Rhythmbox won't import or play flac files

  - by Dan Drake

  I have a new installation of 12.04 and I just copied over all my music to the ~/Music folder. Rhythmbox found all the mp3 and ogg files, but it refuses to import flac files. They simply do not appear in my music library. If I start Rhythmbox on the command line and try to import a folder that contains flac files, absolutely nothing happens. Nothing is imported; no error messages. I have all the dependencies for Rhythmbox installed, along with all the suggested and recommended packages. I can play a flac file with gst-launch-0.10 and gst-typefind-0.10 correctly identifies flac files as audo/x-flac. Why does Rhythmbox refuse to see flac files? What can I do to find out what is happening?

• How to reset display settings in XFCE \ Ubuntu 12.04 and also flgrx drivers

  - by Agent24

  I recently upgraded to Ubuntu 12.04 and since I hate unity I installed the Xubuntu package and am using XFCE instead. Since I have a Radeon HD5770 I also installed the fglrx drivers. This all went fine (aside from the fact that the post-release update fglrx drivers have an error on installation and Ubuntu thinks they're not installed when they actually are. I configured my display settings (dual monitors, a 17" CRT on VGA and a 17" LCD on DVI) in the amdcccle program and everything was perfect. THEN, 2 days ago, I accidentally clicked on the "Display" settings in XFCE "settings" manager. After that, everything got screwed. Now, I normally run the CRT at 1152x854 and the LCD at 1280x1024 with the CRT as my primary monitor (with panel) and the LCD without panels etc just to display other windows when I want to drag them over there. The problem is now that if I set my CRT to 1152x864, it stays at 1280x1024 virtually and half the stuff falls off the screen. It also puts the LCD at 1280x1024 BUT then overlays the CRT's display ontop with different wallpaper in an L shape down the right-hand and bottom edges. In short, nothing makes sense and everything is FUBAR. I tried uninstalling fglrx through synaptic, and renaming xorg.conf and also the xfce XML file that has monitor settings but it still won't make sense. Unity on the other hand can currently set everything normally so the problem appears to be only with XFCE. In any case, I can't even get the fglrx drivers back, when I re-installed them, I can't run amdccle anymore as it says the driver isn't installed!! Can someone help me reset my XFCE settings so the monitors aren't screwed with some incorrect virtual desktop size and also so I can get fglrx drivers back and working? I really don't want to have to format and reinstall and go through all the hassle but it looks like I may have to :(

• Sitronix ST9RM01 touchscreen not working

  - by Josh Kelley

  I have a Sitronix ST9RM01 touchscreen that I'm trying to get working with Ubuntu 12.04. The touchscreen is apparently recognized by Linux and X - the hid_multitouch module is loaded, and lsinput and xinput both list the touchscreen as an input device - but touching the screen does absolutely nothing, and xinput test shows no events. The same touchscreen works just fine in Windows. How can I troubleshoot from here? Any suggestions?

• How can I adjust system volume from within XBMC?

  - by d3vid

  While running XBMC, I can adjust the volume of the XBMC application itself. However, this volume is limited by the current system volume. For example, if the system volume is at 80% and XBMC is at 100%, I am effectively at 80% and cannot go higher. Or if the sound is too soft and needs a boost, I would normally increase the system volume beyond 100%. XBMC takes over the whole screen, so the system volume is not accessible. Pressing the Super key brings up the dash and top menu, but clicking on it is difficult and inconsistent, and very quickly XBMC takes over the screen again. How can I adjust the system volume without having to quit XBMC?

• rsnapshot for remote backups...

  - by Patrick

  I want to use rsnapshot to make backups from my production server to a remote backups server. Should I install rsnapshot on the remote backup server and not the production one, right ? rsnapshot is going to pull the files to backup from the production server and store them locally on the backup server ? I've just realized that I don't have sudo privilegies on the backup server. Does this mean I cannot use rsnapshot for remote backups ? thanks

• Lubuntu with only Ubuntu's workspace/tiling features

  - by Johnny Tremain

  I searched around for a long time but found nothing. I am moving from Ubuntu to Lubuntu. Everything is great (I am okay with the bland style) except for three features that I use regularly in Ubuntu. 1) Win+w / Win+s zooms out to see an overview of the current workspace and all the workspaces respectively. 2) Ctrl+Alt+num which puts the current application in a specific portion of the workspace. 3) Snap to edge of workspace. How would I get those three features onto Lubuntu? Would that cancel out the benefit of Lubuntu, so I should just stick with Ubuntu (or any distro you can recommend)? Thank you.

• How do I detect if I'm in a 'full screen' bash shell or GUI terminal window?

  I have some code in my .bashrc that sets the terminal window title using the currently running command and it works great in Unity, where the terminal is in a window. However, when I'm logging in with the Ctrl + Alt + F1 terminal (whatever it's called), my prompt gets filled with garbage that is various escape sequences that set the (nonexistent) window title. How can I detect from within a bash script if I'm in one or the other?

• Does Ubuntu run on current Asus Transformer Prime?
