• Oneiric updates cause "Window Creation Error" in Second Life client

  - by Yuttadhammo

  With the latest Oneiric updates, I've been unable to use Second Life, a virtual reality simulator, in Ubuntu. I assume it has something to do with the NVidia driver, since the error in the console says: WARNING: createWindow: LLWindowManager::create() : Error creating window. WARNING: LLViewerWindow: Failed to create window, to be shutting Down, be sure your graphics driver is updated I guess I could file a bug on Launchpad, but I'm not sure where to file it. Does anyone have any insight into what may be causing this problem? It was working fine a week ago, and older viewers (Imprudence viewer anyway) still work fine.

• How do I install drivers for a Konica Minolta 200?

  - by th3pr0ph3t

  This copy machine / scanner / network printer works with Windows but no drivers are available for linux. When Ubuntu supports a printer it works fine but this one is not supported. I found the drivers in: http://onyxftp.mykonicaminolta.com/download/SearchResults.aspx?productname=bizhub%20200 //But I don't know how to install them, nor which one to download. //How can I install this driver? EDIT: The file with the driver is here http://onyxftp.mykonicaminolta.com/DownloadFile/Download.ashx?fileid=18571&productid=865 Inside the archive there is a .deb package that installs correctly but doesn't work. So far the question is: "How can I make it work?"

• Installed nvidia graphics driver (current, 8800GTX) has issues, how do I disable/uninstall it?

  - by Craig

  I installed the restricted nvidia graphics driver (current) on my computer, then restarted to finish the install. Upon reboot I got some prompt about there being an X server problem, It told me to try auto-fixing or something, none of its options worked, they all failed horribly and caused the computer to crash immediately on selecting any of them. I decided to re-install. Again I got in, downloaded updates, and installed the driver. This time upon boot the X-server immediately crashes and im brought to tty1. If I hit ctrl+alt+F7 I see a beige-background prompt says the usual about checking battery state, pulse audio etc., you see right before the x-server starts. According to X (if I do sudo startx) there are no displays, and the nvidia graphics driver is not working. First off, how do I set ubuntu back to the default driver (I have only a CLI right now -.-), then how do I install a more appropriate nvidia driver

• how to un-install a special driver/kernel in 13.04

  - by hako

  I have tried to install a special ATI driver using a method described in http://debianhelp.wordpress.com/2012/09/28/to-do-list-after-installing-ubuntu-13-04-aka-raring-ringtail-operating-system/ Details: Alternative ATI Legacy Video Driver PPA installation for (for < 5000 series cards): sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev* sudo add-apt-repository ppa:makson96/fglrx sudo apt-get update sudo apt-get upgrade sudo apt-get install linux-headers-generic fglrx-legacy sudo aticonfig --initial And then reboot. There were a couple of warnings at "sudo apt-get install linux-headers-generic fglrx-legacy" with update-alternatives. But, at the last step I got "aticonfig: No supported adapters detected". Unity does not start anymore. I only can login to Gnome. How can I get back to a working system?

• Is it possible to configure Apple's Magic Mouse to be recognised on start up?

  - by Dave

  This question may apply more roundly to all bluetooth mice but in my case I am dealing with an Apple Magic Mouse. I have followed the set up instructions here; https://wiki.ubuntu.com/Multitouch/AppleMagicMouse closely. I have even removed the mouse and started from scratch more than once repeating each step described carefully. Every time the computer is started it does not see the Magic Mouse by default. I need to keep a wired mouse connected to the computer at all times which I use to log in with then connect the Magic Mouse, in a somewhat counter-intuitive exercise! Any help would be greatly appreciated.

• Using two ethernet connections (Internet enabled) simultaneously

  - by vedarthk

  I have searched and read over the Internet and also on askubuntu. i am using Ubuntu 11.04 and my question or the thing that I want to achieve is efficient use of both the connections and thus increasing my browsing and downloading speed. I want my system to decide which packet should be routed over which interface. I want to know if this is possible. For example, Is it possible to route alternate packets over the two interfaces ? Please let me know any Internet resource or If I would have to insert any code into the network drivers etc. ?

• How do I script to open a set of programs each on specific desktop?

  - by Jahn

  I looked around for a while and could not figure out the answer to my following problem: I have a setup of six desktops on Ubuntu 12.04 with Unity. On start up, every morning, I go through a routine of opening the same five or six programs. I open each on a specific desktop. I would like to have this automated. Is there a way to script or configure this? Additional question: To further complicate the matter, I am running two screens in twin view mode. I actually need to start each program on a specific screen, preferably in full screen. Thanks in advance, Jahn

• How can I use a CanoScan N640Pex scanner over a USB/parallel cable?

  - by detly

  I have an old CanoScan N640Pex flat bed scanner and a USB-to-parallel port cable through which I can connect it to my PC. Unfortunately neither Simple Scan nor XSane detect the scanner. I'm running Ubuntu 12.04 (plus updates and backports) with kernel 3.2.0-31-generic. dmesg tells me this when I plus the cable in: [256411.641910] usb 7-1: new full-speed USB device number 10 using uhci_hcd [256411.872392] usblp0: USB Bidirectional printer dev 10 if 0 alt 1 proto 2 vid 0x067B pid 0x2305 [256411.872417] usbcore: registered new interface driver usblp lsusb shows this device for my cable: Bus 007 Device 010: ID 067b:2305 Prolific Technology, Inc. PL2305 Parallel Port The device node created is /dev/usb/lp0 crw-rw---- 1 root lp 180, 0 Sep 9 17:46 /dev/usb/lp0 There is no extra information from any of these commands when I attach the scanner to the cable and power it on, though. I suspect I might need to change something in /etc/sane.d/canon_pp.conf, but I have no idea what to put for the ieee1284 line, since there is pretty much zero documentation for that parameter. So how can I get it to work?

  I have Ubuntu 12.04 installed on my machine. I also installed Virtualbox so that I can run windows 7.

• Distorted text in programs

  - by Teneff

  I've installed Ubuntu 11 with gnome and in some point the text in the programs becomes unreadable like this. It's not only the text, but even the desktop background looks awful.

• How can I fix the compiz effects lag in unity?

  - by Samir

  I've recently installed ubuntu 11.04, and I actually liked Unity (although many others prefer Gnome), but there seems to be a lag problem. Every time I press the super button to bring out the Dash, or Super+W to show all windows, or any other action that involves some sort of effect, the effect lags a bit, and it could get really annoying. I've seen a fix using CompizConfig Settings Manager, but that doesn't seem to work for me. I've got a NVidia 9800 GT 1 GB video card, a 2 GB Ram, and not sure about the CPU (if you need it, tell me and I'll figure it out). Any help would be appreciated Thanks in advance.

• Configure DNSMASQ to use /etc/hosts file

  - by casey_miller

  I have installed DNSMASQ but it was not starting as 53 port was busy. I found out that ubuntu already had dnsmasq package and it's working. Now the problem is...I just want to be able to resolve my hosts in /etc/hosts through it i.e: nslookup somehostonlan localhost to be resolved to certain IP taken from /etc/hosts file. but this is not happening. Why? BTW, as the caching DNS server it's working fine. I just want it to resolve hosts from /etc/hosts file that's all

• No user/password boxes on login screen after updates today (June 30, 2012)

  - by Tony

  Just installed today's batch of updates, including new kernel 3.2.0-26 and rebooted. Now the screen just has a logo in the middle and "Ubuntu 12.04 LTS" in bottom left corner, but no box to choose which user to log in as, or to enter a password. CTRL-ALT-F1 gets me to a "login:" prompt, and I can log in - but I have no idea what to look at to find out what is wrong, or to fix this. Tried older kernels and recovery mode for current kernel - no joy, still no way to log into the graphics console.

• Is there ongoing work in the kernel team to improve battery life under linux?

  - by leousa

  I have read in some forums that the kernel team is working on improving battery life and energy efficiency in linux. Unfortunately our community really lags behind windows and mac in that regard. I would like to read about the reasons why this difference exists with other platforms. Is it purely due to closed hardware specs from vendors or does it has to be with kernel design issues? Apple devices with unix cores have amazing battery times, but they also design their own hardware...just want to understand this issues in a less technical way I know that recent kernel updates in Ubuntu have improved the battery life in most computers, but I was wondering if there is still development going on and where can I read more about it. Thanks in advance

  - by gcc

  I am looking an open source application. Application should have : * database support ( create two or three table ) * GUI ( what I have created should be seen ) Example : Assume that I have created a table ; X_table : | A | B | C | D | After creating table, I am loading data | A | B | C | D | | 1 | 11 | b | f | - | 3 | 12 | a | o | - data | 4 | 13 | r | o | - When I am opening application not for loading data, I want see data in graphical interface. Are there any open source application which have above feature ? Application can be so simple, * no internet connection * support only one database * static table creation ( once created never changed ) Application can be run Ubuntu 12.04 and/or Windows. In other words, I am wanting database viewer and editor. EDIT: I should load pdf file, image etc. or give path of the file to the application. This link can be reference to my question . ( Interface should be like this, just a list )

• On a dual monitor setup, how can I set which lone monitor the ALT-TAB interface appears?

  - by conner_bw

  On a dual monitor setup, how can I set which monitor the ALT-TAB (or ALT+`) interfaces appear? Right now, it's flying all over the place, possibly based on on which app is focused? I'm not sure. In any case this is not useful to me. I spend 80% of my time staring at the monitor in front of me, and sometimes I turn my head to the left to look at logs, or whatever. When I press ALT-TAB or ALT+`, I want the interface to appear, 100% of the time, on the monitor in front of me. Geforce GT 430, NVIDIA binary drivers, Ubuntu 12.04 LTS. Help?

• Windows 7 and 11.10 side by side from scratch what am I doing wrong?

  - by Bill.Caffery

  I have tried everything I can think of at this point and I'm at a total loss. I have a 2TB drive I want to install Windows 7 and 11.10 (both are 64 bit) side by side, but once I install Windows it must need gpt to work or something because no matter how many times I've removed it, it always returns. If I use gdisk and set the disk as mbr, Windows won't load. Now this last time I ran gdisk and tried to boot into Windows before I installed Ubuntu all the way and ended up at a grub rescue prompt. Any help please? Also let me say I have been searching and reading for days and have tried everything I can find to make this work so this isn't a one time event, it's continual.

• Restore the Ctrl + Alt + Num Pad windows positioning commands?

  - by holocronweaver

  Using Unity in Ubuntu 12.04, the Ctrl + Alt + Num Pad combination for positioning windows has been fragmented by Ctrl + Alt + 4 (move window to left half of screen) being changed to Super + Left Arrow. A similar change moved Ctrl + Alt + 6 to Super + Right Arrow. Thus one moves windows to corners using Ctrl + Alt combos, but Super combos are needed to move to the left or right. This is more than a convenience problem since the new windows positioning provided by the super key combos seems to give different sizes than the Ctrl + Alt combos they replaced, leading to distracting gaps between windows when you combine the two methods to position three or more windows on one screen. Is there a way to restore the previous behavior so that I can use Ctrl + Alt + Num Pad for all windows positioning?

• Will everything (downloaded fonts, files, apps etc) remains the same when I upgrade from Maverick to Natty?

  - by Suffi

  I'm planning to upgrade from Maverick to Natty, and to try out Unity, but I don't want to lose any settings, customizations and downloads in Maverick. I just want to know, if upgrading alter anything that I said earlier? I don't want to start over with a clean, fresh Natty, and I hope I can keep all of my files and folders and settings in Maverick, and to have them in Natty after the upgrade. Is this possible? Should I use Update Manager to achieve this? And would all my compiz-settings be reset after I upgrade? Sorry for too much questions, but I'm asking this because you know, in Windows, any version upgrade would require the disk to be reformatted. I hope Ubuntu is more convenient than that.

• juju: How do I list all the relation variables and debug them interactively?

  - by mfisch

  I'm writing a charm that requires a mysql database, I found from looking at other charms that this (below) is how I get the info about the database: user=`relation-get user` password=`relation-get password` mysqlhost=`relation-get private-address` But I just found that from reading the wordpress charm example, is there a way to show all the relation variables that I can use? Also, while debugging my db-relation-changed script, I wanted to ssh into my host and interactively run those commands, for example relation-get user, but it didn't work. I resorted to having to restart everything and use juju log to print them out. This wasted a lot of time. Is there a way to print out these relations, either from my dev box or from the instance running my charm? (Below is what happens when I tried to interactively run relation-get): ubuntu@mfisch-local-tracks-0:~$ relation-get user usage: relation-get [-h] [-o OUTPUT] [-s SOCKET] [--client-id CLIENT_ID] [--format FORMAT] [--log-file FILE] [--log-level CRITICAL|DEBUG|INFO|ERROR|WARNING] [-r RELATION ID] [settings_name] [unit_name] No JUJU_AGENT_SOCKET/-s option found

• How to be anonymous on IPV6 protocol by not using MAC address in EUI-64?

  - by iugamarian

  The IPV6 protocol has a feature called "Extended Unique Identifier" or EUI-64 witch in short uses the MAC address of the network card when choosing an IPV6 Adress. Proof: http://www.youtube.com/watch?v=30CnqRK0GHE&NR=1 at 7:36 video time. If you want to be anonymous on the internet (so that nobody can find you when you download something, etc.) you need this EUI-64 to be bipassed in order for the MAC address not to be discovered by harmful third parties on the internet and for privacy. How do you avoid EUI-64 MAC address usage in IPV6 selection in Ubuntu? Also for DHCP IPV6?

• How to hide process arguments from other users?

  - by poolie

  A while ago, I used to use the grsecurity kernel patches, which had an option to hide process arguments from other non-root users. Basically this just made /proc/*/cmdline be mode 0600, and ps handles that properly by showing that the process exists but not its arguments. This is kind of nice if someone on a multiuser machine is running say vi christmas-presents.txt, to use the canonical example. Is there any supported way to do this in Ubuntu, other than by installing a new kernel? (I'm familiar with the technique that lets individual programs alter their argv, but most programs don't do that and anyhow it is racy. This stackoverflow user seems to be asking the same question, but actually just seems very confused.)
