• HP DL360 G4 screen resolution problem

  - by dogmatic69

  I just bought an old blade server to mess about with at home and cant get the thing to work. I have run the installer 11.10 x64 server and that was fine. After installing and rebooting, POST is fine but when grub kicks in the screen shows a popup type box complaining that it cant use the resolution. I have tried different screens and its always the same. I can reboot and go back into the installer and the screen is fine. I tried to follow some guides on-line about changing the resolution but I cant get a terminal. I found one in the installer but that is using the ram as /. the installer says 'the drive is mounted as "/target"' but I don't see that, nor /mnt/target. Could anyone help me configure this and get it running. Thanks.

• Cannot authenticate without a password

  - by user70267

  This question has been asked hundreds of times before, but I did not see any relevant answer so I will repost. Sorry if there is any helpful answer, please don't vote down but please link to the question(s) with such answers. The problem can be reproduced as follows: When I remove the password of an administrator account, "Log In without Password", I cannot use that account to authenticate. When I do something that requires authentication, I cannot use an admin without a password to authenticate. If I leave the password box blank without a password while choosing a non-password admin, authentication fails (in terminal or in GUI). How to fix this problem?

• Steam, launching Team Fortress 2: libGL.so.1: wrong ELF class: ELFCLASS64

  - by stefanhgm

  After I got Steam running with the workaround mentioned here, I've got nearly the same problem when launching Team Fortress 2. After starting it from Steam the "Launcher" pops up and after a few seconds it disappears with the following error in the terminal: /home/user/Steam/SteamApps/steamuser/Team Fortress 2/hl2_linux: error while loading shared libraries: libGL.so.1: wrong ELF class: ELFCLASS64 Game removed: AppID 440 "Team Fortress 2", ProcID 5299 saving roaming config store to 'sharedconfig.vdf' roaming config store 2 saved successfully Because of the similarity with the workaround I used before, I tried to execute: export LD_LIBRARY_PATH=/usr/lib32:$LD_LIBRARY_PATH directly before launching the game, but there is no difference.

• Can't get my Blue Snowflake Mic to work

  - by TheNerdAL

  It was working fine when I bought it. I think it was an update or something that made it stop. I don't think the Mic is broken, at least I hope not. Can anyone help? Please? I need it before tommorrow. I'm working on a video. I get this when I check the terminal for what USB devices are connected: Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 004: ID 2525:8912 Bus 003 Device 003: ID 058f:9360 Alcor Micro Corp. 8-in-1 Media Card Reader Bus 003 Device 002: ID 056a:00d2 Wacom Co., Ltd Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Thanks.

• How to reset Compiz/Unity to defaults?

  - by Stramato

  I tried to activate some compiz effect via ccsm (I think wobbly windows) and compiz crashed and froze up the screen. So I used the Control+Alt+Backspace keystroke to force logout. Then I logged back in. Unity wasn't there, just a (non-unity) panel at the top with file, edit, and the like. I was able to pull up a terminal and launch ccsm, only to find almost all settings wiped out. I turned everything back on that I thought should be on, but I don't know if I got everything. Also, now whenever I open up a non-maximized window, it opens up in the top left corner with the title bar behind the unity panel. So what I need is a list of everything that needs to be on in ccsm, and a way to get windows to NOT open in the corner, preferably without having to reset unity or compiz.

• How to fix "error: unknown file system" on all available partitions

  - by Jonathan

  I've had a running problem with removing Linux from my Windows 7 laptop. Initially, it was installed as a dual-boot, and worked well. To remove, I deleted the partitions on my laptop. This removed grub, and I was left with needing to enter: set root=... set prefix=... insmod normal normal each restart. I didn't restore the Windows boot-loader and have since re-partitioned my drive. Now, upon reaching the command prompt screen, an ls query showshd0, with three partitions, but none of them have a recognizable boot-loader as each returns with error: unknown file system. Booting from a Windows 7 rescue disk doesn't seem to work, as it sends me to the same command prompt terminal. All I'm looking to do is restore the boot-loader, either grub or Windows 7. Any help would be appreciated. Thanks in advance.

• Some applications (Anki, Okular, Calibre) start very slowly

  - by k1U

  When I start one of the applications mentioned in the title from the terminal, I get this: Registered DEC: true Error in contacting registry "org.freedesktop.DBus.Error.NoReply" "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." Could not query active accessibility event listeners. Registered event listener change listener: true Currently I am running 12.04 This problem started a couple of days ago, shortly after I've installed okular from within the software center. by "slow" I mean it takes about 30 seconds. Other applications like chromium start instantly.

• How can set up a file sharing server to allow remote access over a WAN?

  - by pst007x

  I want to set up a server to allow remote access over a WAN. The purpose is to allow people to remote connect and download specific files from a specified folder hosted on the server. Is there software available to achieve this, preferably with an interface so I can easily add and remove users, plus monitor who is connected at any time? I have looked around and only found terminal references, and not very clear how to set up. I have a service running on my Win server, but I am hoping to move from that to Ubuntu for my file sharing. I do not want people who access the server to have any local accounts or any access to any folder/files apart from authorised folders/files. Thanks

• 12.04 indicates filesystem check on next boot, but never does one

  - by pcm

  Just installed 12.04 32 bit on my machine, with 3 drives. When I open a terminal window or ssh in remotely, I see: Welcome to Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-29-generic-pae i686)  * Documentation:  https://help.ubuntu.com/ *** /dev/sda1 will be checked for errors at next reboot *** *** /dev/sda2 will be checked for errors at next reboot *** *** /dev/sdg1 will be checked for errors at next reboot *** Last login: Fri Aug 31 08:15:41 2012 from .... However, if I reboot, I never see it doing a disk check on boot up, like I used to see with 10.10. Note, after install, I was not seeing the grub menu on boot. I made a ISO disk with BootRepair and now I get the normal grub menu. Any idea as to why the disk check is not happening on boot (I know I can boot a Live CD and then check the disk - I just want the check on boot working)?

• Nautilus uses different permissions for mounted drives

  - by farhad0011

  I've written two bash scripts to give read-only or read/write access to my NTFS partition: read-only access: sudo umount /media/Data_Drive/ sudo mount -t ntfs-3g -o ro,user,auto,nls=utf8,umask=0000,uid=1000 /dev/sda2 /media/Data_Drive read/write access: sudo umount /media/Data_Drive/ sudo mount -t ntfs-3g -o rw,user,auto,nls=utf8,umask=0000,uid=1000 /dev/sda2 /media/Data_Drive It works perfectly if I only use terminal to work with the files. It also works with Nautilus in read-only mode but not in the read/write mode. In fact, Nautilus gives me an error when I try to copy a file to Data_Drive saying "The destination is read-only". More funny, when I look at the permissions (by right-clicking on Data_Drive and then properties-permissions) I have all the required permissions to write a file in Data_Drive! I am so confused why Nautilus behaves strangely. I appreciate if anybody could solve the mystery!

• How do I run Conkeror in Emacs?

  - by Anake

  I have been using emacs for about 3 months, and have been amazed by how much improved my interactions with my computer are. I now use eshell rather than a separate terminal, and the last thing I still need to leave my emacs environment for is for my web browser. I have been reading up on Conkeror, and it seems almost ideal (emacs keybindings, no need to use the mouse etc.) but it runs in a separate window. If it could be run within emacs, it would mean that I would never really have to have interaction with the actual OS, which would be good for someone who is forced to rotate between linux, mac and windows (i.e. me). I understand that it couldn't be run from emacs in -nw mode, but would it be possible (or likely) that Conkeror could be setup to run within an emacs window? Note: - I've tried w3m and didn't really like it

• 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"

• How do I change my PYTHONPATH to make 3,2 my default Python instead of 2.7.2?

  - by max

  I have python3.2 located in /usr/lib/python3.2. I am not sure if that means it's installed but I assume it is for now. Some facts about my system: $ which python /usr/local/bin/python When I type python in terminal I get the following $ python Python 2.7.2 (default, Dec 19 2011, 11:12:13) [GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. Then to find the path I do >>> sys.info >>> sys.path ['', '/usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg', '/usr/local/lib/python2.7/site-packages/pip-1.0.2-py2.7.egg', '/usr/local/lib/python2.7/site-packages/PIL-1.1.7-py2.7-linux-x86_64.egg', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages'] So knowing all of this, how do I change my default system python from 2.7.2 to 3.2?

• How to specify 'root' in path in text file

  - by DeanGrobler

  I'm following this tutorial located here on how to create a launcher for eclipse in unity. Everything is going pretty well so far, I've managed to successfully create the launcher but when I click on it, my system complains that the path to the exec is wrong. My exec for eclipse is located here: ~/opt/eclipse/eclipse And if you look at the tutorial you have to create a file and set it's contents like so: [Desktop Entry] Type=Application Name=Eclipse Comment=Eclipse Integrated Development Environment Icon=eclipse Exec=./opt/eclipse/eclipse Terminal=true Categories=Development;IDE;Java; In my case I have to provide the full location for the exec and there are a number of things that I tried that didn't work I set 'exec' to 'Exec=~/opt/eclipse/eclipse' , 'Exec=/opt/eclipse/eclipse' and 'Exec=root/opt/eclipse/eclipse' and none of these worked.. What should I set it to in order to fix the path so that my luancher works? Update------------------ I tried to list those 2 directories and what i get is this:

• Skype on Ubuntu 12.04 x64 - anyone has it installed?

  - by Zevaka

  I am wondering if there's anyone here who managed to use skype @ 12.04. It used to work (ever since i first tried Ubuntu 10.04) flawlessly, but after upgrade to 12.04 just doesn't start. If I start skype from terminal, it just says "Segmentation fault (core dumped). I tried to remove skype and installed it from different locations: Skype website (did not install at all, "package error") From official Ubuntu repository (doesn't start at all, segmentation fault) From repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner" (doesn't start at all, segmentation fault) Interesting thing: even if I remove / purge skype from the system, it still shows up in Unity menu (of course doesn't start). Any help here? Thanks!

• Automatically move Xubuntu panel to external monitor

  - by user1291235

  I am using xubuntu 13.04 with a dualmonitor setup. (external monitor as primary, laptop als secondary) I am using xandr to makeup my monitorsetup. However I recognized that the xubuntu panel on the top by default will always be placed on the laptop monitor. I know that i can move the panel via the panel preferences. This works. But i want to somehow either let it move automatically to the right monitor (the primary one) or to move it with a terminal command (so i can create a script which takes care of moving the panel to the primary monitor)... any ideas?

• How do I get unity back?

  - by Siva

  I got the latest driver software for my old ATI Radeon 4600, and it had me restart. My screen was then just a big terminal! I could log in, but when I typed 'unity' into it as a command, it said something about DISPLAY not found; set it to :0 (zero). I don't know enough about Linux to deal with this. I am using a DSL live CD to ask this. I looked at similar questions suggested, even searched. If my question's a duplicate, I apologise, but I didn't understand what I saw there. T_T

• How to install again Update Manager after uninstalling it

  - by biezdar

  Ok, the thing is this I tried asking many times on few ubuntu forums how to deal with my non-responsive Update Manager, but all I was getting was the same stuff (run it from the terminal, run some lines, apt-get update blah blah). Nothing was helping. Eventually I went mad Windows style and tried to simply uninstall it and install it again. The problem is - how to install it again? Can't do it through Software Center, can't really build a package (because I'm too stupid to do that). And I seriously want to avoid reinstalling the whole system. I am running a 12.04 verison (Update Manager was unable to update to a newer one) Please help. I am furious with this thing.

• Script for Creating Multiple ZIP archives from Multiple Folders

  - by user39288

  I want to be able to right click multiple folders inside of a directory in nautilus, and be able to create seperate zip archives from those folders in that same directory. If possible it would also be great if it automatically deleted the old folders. So, if I have 30 folders, I want to select those using control-shift, then go to scripts and run the script, and just have those 30 folders compressed into seperate .zip archives, and have the old folders deleted (if possible). Anyone know how to accomplish this? I suck with terminal, and am looking for a script solution.

• How to connect to the internet via command line or graphical utility given I can't click at the top of the screen?

  - by Ben

  My Ubuntu 12.04 installation has an input problem resulting preventing me from clicking near the top of the screen. That is, there is an unclickable area, circa 60 pixels high and stretching all the way across the screen. I will ask about this in a later question. For now, I would just like to be able to connect to the internet, given this limitation. I am able to access the network connections application by hitting the super key and typing "network connections". There is a LAN and a wireless network available. The network icon in the bar at the top of the screen shows an empty wedge, which I suppose means that wireless is off. I've attached the cable for the Ethernet connection, but it does not seem to have connected automatically. How can I figure out what's going on? (I'll happily edit in the output of any relevant terminal commands.) Thank you.

• Internal HDs that don't contain the OS aren't accessable unless I try to manually browse them

  - by Hrafn

  So I have 4 internal hard drives, one that contains the OS (Ubuntu 12.04), all ext4. After starting the computer up, and without having tried to access the drives (File manager, terminal etc) it seems like the drives haven't been mounted. If I go into the "Disks" utility I see that the disks haven't been mounted. Programs that try to access the HD's during startup throw an error. For example my music player can't find the library, my note taking software can't find the database etc. But after opening the drive in a file manager everything works. I've checked SMART on all the disks and everything is a ok. Any and all ideas would be appreciated.
