• Kubuntu 11.04 bad experience, Gimp crashes and other bugs

  - by giowck

  I installed Kubuntu 11.04 64bit today. First let me expose some issues, this is not a rant, just some observations on Kubuntu 11.04 :) Flash doesn't work. The package "flashplugin-installer" was installed by rekonq. But still no flash. Additional Drivers (jockey-kde) doesn't show up automatically after first login. I tried to delete a large file (19,2 GB), an error appeared: "Please empty the trash first, no more space available" or something like that, but you know what? My trash was empty! (Then I found in Dolphin the settings to increment the max size of the trash). Amarok has no play/pause/forward/back buttons, only after changing settings to show those buttons on the top bar. GTK applications like ubuntu software center, inkscape... are in english, but my default language is "german". Only gimp allows to install the "de" language pack. The numblock turns off after each restart. In the KDE Control Center, the "remember last state" of numblock is set. But this is not working. I had some crashes: Nepomuk, Policy-kit, plasma-workspace and gimp. But now to the important stuff. I really need Gimp to work. After starting it, I get a crash: giowck@giowck-desktop:~$ gimp (gimp:1899): GLib-WARNING **: /build/buildd/glib2.0-2.28.6/./glib/goption.c:2132: ignoring no-arg, optional-arg or filename flags (8) on option of type 0 Speicherzugriffsfehler (in English: "Memory error") What can I do to run Gimp? Thanks

• Lenovo ThinkPad L520 slows down when AC power adapter is plugged in

  - by Aamir

  I have a new laptop Lenovo ThinkPad L520 (7859-5BG) Core i5-2520M(2.5GHz) with 4GB RAM. Having installed Ubuntu 11.10 32-bit, while browsing with Chrome on GNOME classic (no effects), I noticed 173% CPU usage by chrome browser process, and the system slowly got very very slow, Now, at this stage as I removed the power adapter, the system suddenly got faster (and stopped the lagging behavior) and CPU usage drops down to 48% !! Observation 1: I was browsing through chrome when my system seemed to be seriously lagging, so I killed chrome to see if it gets any faster. But there remained no difference. Notice that CPU usage was a bit strange here. It showed no high activity, but as soon as I would click on applications in gnome panel, it would shoot CPU usage to 70, or 80 or 90 or 143% etc. depending on how quickly i clicked back and forth. At this instance I removed by AC adapter of my laptop, and suddenly system got fine. So i again clicked on gnome panel, and noticed that it now took only 7% or 12% or 13% at max, with same kind of clicks in application menu. Observation 2: At the other times, with AC adapter plugged in, top indicates four instances of chromium taking 90%, 60%, 47% and 2% (for example), and then once I take out the AC adapter same processes take lesser CPU all of a sudden Intermediate conclusions: What does this indicate ? I cannot figure out any "other" process in "top" that is suddenly being triggered, its the same process that hogs up my CPU once AC power is plugged in ! NOTE: the problem is now CONFIRMED, as i can repeat that when I have power adapter plugged in ! Can anyone tell me what exactly does this indicate ? What is wrong, is it some bug with power management or what ?

• Setting different default applications for different Desktop Environment

  - by Anwar

  I am using Ubuntu 12.04 with default Unity interface. I installed later the KDE desktop, XFCE, LXDE, gnome-shell and Cinnamon. The KDE comes with different default applications than Unity, such as kwrite for text editing, konsole as virtual terminal, kfontview for font viewing and installing, dolphin as File browser etc. Other DE come with some other default applications. The problem arises when you want to open a file such as a text file, with which can both be opened by gedit and kwrite, I want to use kwrite on KDE and gedit on Unity or Gnome. But, there is no way to set like this. I can set default application for text file by changing respective settings in both KDE and Unity, but It become default for both DE. For example, If I set kfontviewer as default font viewing application in KDE, it also opens fonts when I am in Unity or Gnome and vice versa. This is a problem because, loading other DE's program takes long time than the default one for the used DE. My question is: Can I use different default applications for different DE? How?

• Error installing avogadro with CMake 'lconvert: could not exec No such file or directory'

  - by Orr22

  I'm brand new in ubuntu. I'm trying to install Avogadro. The program need the following packages, which I could install: CMake - OpenBabel 2.3.2 - Qt4 - Git - Eigen2. Here it is the recepy to install the : cd $HOME/src git clone git://github.com/cryos/avogadro.git mkdir -p $HOME/build/avogadro cd $HOME/build/avogadro cmake $HOME/src/avogadro make -j2 sudo make install It was unable to compile, but when I skipped the 'git clone' step it seemed to work just fine. After several stops during the CMake compiling process (software actualizations, get Doxygen, get flex, get bison) I was able to compile. But when I introduce the 'make -j2' command the installation stops as follows: Orr22@javi-87:~/build_avogadro$ make -j2 [ 0%] Built target elementcolor [ 0%] Built target bsdyengine [ 2%] Built target spglib [ 3%] Built target navigatetool [ 4%] Built target tubegen [ 4%] Generating libavogadro_hu.qm [ 6%] Built target OpenQube [ 6%] Generating moc_animation.cxx lconvert: could not exec '/usr/lib/i386-linux-gnu/qt5/bin/lconvert': No such file or directory make[2]: *** [libavogadro/src/libavogadro_hu.qm] Error 1 make[2]: *** Se espera a que terminen otras tareas.... make[1]: *** [libavogadro/src/CMakeFiles/avogadro.dir/all] Error 2 make: *** [all] Error 2 Any suggestions to proceed?

• "Failed to create swap space" error during installation

  - by Welsh Heron

  I've been trying to install Ubuntu for the past two days or so, but I've been running into a problem: every time I run the installation program on the LiveCD, I always get the same (or a very similar) error: "Failed to create Swap space The creation of swap space in partition #3 of SCSI5 (0,0,0)(sda) failed." So far, I've run DBAN (Darik's Boot and Nuke) on my HDD once, to make absolutely sure that everything on it had been erased. Then, I simply put in the LiveCD, and let it run the automated install. I get the above error directly after I tell it to automatically partition the HDD (it will work for a second or so, then this will pop up), forcing me back to the screen that lets me choose whether I want to automatically or manually partition the HDD. Well, after failing to install the software manually, I did a little research and learned enough about partitioning Linux to use the 'Manual partitioning' option. I partitioned the HDD as follows (it's a 1TB drive): /home - (the rest)- ext2, / - 20GB - ext2, /boot - 100MB - ext2, /swap - 8GB /EFIboot - 40MB The only difference when I tried this method was that I got THIS message: "Failed to create Swap space The creation of swap space in partition #2 of SCSI5 (0,0,0)(sda) failed." Basically, the only difference was that there was now a '2' instead of a '3'. If I may ask, what exactly am I doing wrong? I've tried looking around the internet (that's basically all I've done for the last two days), but no one seems to have the same problem that I have, and I've tried most of the solutions for similar problems (DBAN, formatting partitions in ext2 format, etc). The only thing I haven't tried is using the terminal to manually partition the HDD...and I actually DID try to do this, but I wasn't able to get past 'su' 's password demand, so I wasn't able to use the terminal. Thank you for your help in advance. ~Welsh

• Restore audio settings - cannot open mixer: No such file or directory

  - by Alfred M.

  The internal speaker of my laptop never functionned under Ubuntu. I tried to follow indication on the web and now the jack audio does not work either. The graphic interface for audio management now displays a 'dummy output' instead of the three possible outputs I used to have (one of them was working for the jack output). In a terminal alsamixer raises an error: cannot open mixer: No such file or directory I did try to remove and reinstall alsa-utils but it did not change anything. This happened after a failed atempt to install alsa-driver-linuxant_1.0.23.1_all.deb from here. My sound card seems to be not recognised anymore. After reboot I have no more the sound icon in menu bar the upper right corner. I think I have removed my sound card driver. Indeed, the command sudo lshw -class multimedia indicated audi device as unclaimed. Any idea how I could revert to a better situation (that is jack support and alsa working)? EDIT: The command lspci -nnk | grep -iEA3 audio gives lspci -nnk | grep -iEA3 audio 00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03) Subsystem: ASUSTeK Computer Inc.

• Wubi shows error

  - by Quirk

  I tried installing Ubuntu 12.04 using Wubi and it just doesn't work, every time, without fail. I had the following scenarios: 1. I downloaded only wubi.exe and ran it. The wubi installer started downloading the amd64.iso using torrent. But when there were just about 40 secs left to download, it shows an error 404: File not found. 2. I downloaded the iso file seperately and put it in the same folder as the wubi.exe. Now there are two cases: a. Offline: wubi says it could not download the metalinks file and hence cannot download the iso. So I download the meta files separately and place them in the same directory. wubi shows the same error again. b. Online: wubi works in same way as in case 1. and the same problem occurs as in case 1. In short wubi doesn't recognize the already downloaded iso in the directory at all. 3. I burn the iso into a Cd and run it. The same thing occurs as in Case 2. Just in case that you know, I installed SP3 for win XP just before using wubi. While Windows is running alright, is it possible that its causing conflicts for wubi?

• what could cause a script to fail to find python when it has `#!/usr/bin/env python` in the first line?

  - by jcollum

  Trying to get casperjs running on Ubuntu 12.04. After installing it when I run I get: 09:20 $ ll /usr/local/bin/casperjs lrwxrwxrwx 1 root root 26 Nov 6 16:49 /usr/local/bin/casperjs -> /opt/casperjs/bin/casperjs 09:20 $ /usr/bin/env python --version Python 2.7.3 09:20 $ cat /opt/casperjs/bin/casperjs | head -4 #!/usr/bin/env python import os import sys 09:20 $ casperjs : No such file or directory 09: 22 $ python Python 2.7.3 (default, Sep 26 2013, 20:03:06) [GCC 4.6.3] on linux2 So Python is present and runnable, casperjs is pointing to the right place and it is a python script. But when I run it I get "No such file". I can fix it by changing the first line of the casperjs python file from: #!/usr/bin/env python to: #!/usr/bin/python Result: $ casperjs --version 1.1.0-DEV I managed to fix it, but I'm wondering why it didn't work with #!/usr/bin/env python, since that seems to be a normal interpreter line. Do I have something configured wrong? Here are the steps to get casperjs: $ git clone git://github.com/n1k0/casperjs.git $ cd casperjs $ ln -sf `pwd`/bin/casperjs /usr/local/bin/casperjs $ casperjs : No such file or directory

• Emulator PCSX Reloaded - Fullscreen not working on Unity

  - by Leonardo Montenegro

  I have an older PS1 console with a couple of games I bought some years ago. On my pc, I'm using PCSX Reloaded - the best PS1 emulators for Linux I found so far. But I'm having a little issue on Ubuntu 12.04 Precise. I'm using Unity 3D and I'm trying to run some of my original PS1 games on PCSX Reloaded. Everything works nicely, except for fullscreen. I toggle fullscreen and specify maximum resolution for my monitor, but on fullscreen mode, both left and top unity bars aren't getting hidden. I tried changing between other graphic modes like Gnome Classic and Gnome Classic w/o Effects. On both, PCSX shows bars in fullscreen mode, so it isn't an Unity-specific issue, but an emulator problem. It's a bit annoying play games this way, so basically I'm running games on window mode for now. I'm using default OpenGL graphic plugin on this emulator. I tried changing to X11 graphic plugin and fullscreen worked, but graphics on X11 plugin aren't as good as OpenGL one. Anyone know a way to get fullscreen working on PCSX using OpenGL plugin? Or maybe another graphic plugin w/ OpenGL support.

• Delete file then run file at startup

  - by Henry Gibson

  I'm running the music player Foobar2000 through Wine at startup. For some reason when I shutdown Ubuntu the Foobar2000 process is ended abnormally in Wine and when it runs next time I get an annoying "start in safe mode?" message. Not a huge problem, but I'd like it fixed. The safe mode message only appears if a file called "running" is present when Foobar2000 starts (if it isn't deleted when closed properly). So by deleting "running" then starting Foobar2000, the message doesn't appear. I thought it would be easy enough to enter this as a startup command, however it doesn't want to work. The command I am using is rm '/home/henry/.wine/drive_c/users/henry/Application Data/foobar2000/running';'/home/henry/.wine/drive_c/Program Files (x86)/foobar2000/foobar2000.exe' which works fine if I just run it from terminal, the file is deleted then foobar2000 runs. Does anyone know why this isn't working at startup? Also, will this run with a terminal visible? How can I make just the gui appear? Thanks

• enabling a user (created with adduser command) for lightdm graphical login

  - by Basile Starynkevitch

  I just installed Ubuntu 12.04 AMD64 on a new (empty) hard disk (because the previous crashed) Since I am quite familiar with Debian, I created two accounts with the adduser command. Since I am also having an NFSv3 file system, I explictly gave user ids when creating them (for simplicity, I keep the same user id on the home server, running Debian; the user names contain digits; I'm not using LDAP), e.g. # grep bethy /etc/passwd bethy46:x:501:501:Bethy XXX,,,06123456:/home/bethy:/bin/bash # grep bethy /etc/group bethy64:x:501: # grep bethy /etc/shadow bethy46:$6$vQ-wmuchmorethings-2o/:15479:0:99999:7:: Of course /home/bethy exists The actual user name is slightly different, and I am not showing the real entries (for obvious privacy reasons) However, these users don't appear at graphical login prompt (lightdm). And they exist in the system, they have entries in /etc/passwd & /etc/shadow and I (partly) restored their /home I've got no specific user config under /etc/lightdm ; file /etc/lightdm/users.conf mentions # NOTE: If you have AccountsService installed on your system, then LightDM # will use this instead and these settings will be ignored but I have no idea of how to deal with AccountsService thru the command line As you probably guessed, I really dislike doing administrative tasks thru a graphical interface; I much prefer the command line What did I do wrong? How can a user entry not appear in lightdm graphical login? (I need to have my wife's user entry apparent for graphical login). I am not asking how to hide a user, but how to show it in lightdm graphical prompt work-around As I have been told in comments by Nirmik and by Enzotib, lightdm probably don't show any users of uid less than 1024. So I changed all the uid to be more than 8200 (including on the Debian NFS server) and this made all the users visible at the graphical prompt. It is a pain that such a threshold is not really documented.

• Kingston SD reader not working for USB3

  I have a Kingston 4-in-1 Multimedia reader. When my PC was formatted with Win7 it worked fine. I decided to change to Ubuntu 14.04 and now it doesn't work.

• Launcher icon size and window behavior broken

  - by philipp

  I have installed the nvidia driver for my graphic card, just following some tutorials what works fine now. After this I could set the Icon size of the launcher, windows had a nice litte shadow, resolution was better and the windows showed up a nice effect when popping up an or when bringing to full-screen... But today the this was just gone after reboot. What could this be? Nvidia xserver-settings are availible. I installed and reinstalled wine1.5 via the apt-get commands, so this might broke something. What can do to fix this again? Greetings philipp EDIT: I went on searching and all i found was that this problem might be connected to the mode of unit, so there is 2d and 3d, but could also be something else, just because setting the mode brings no change. EDIT 2: the version of Ubuntu is: 12.04 and it is a 64 bit environment the graphic card is: GeForce GT 330M Edit 3: Using maps.google in webGL mode does not work anymore too, it was working yesterday. EDIT 4: the screenshot. btw: I think that blender is not working anymore too... EDIT: 5 I think that the problem is closely connected to this output

• How can I find out which user deleted a directory?

  - by Rob S.

  My Ubuntu server has about roughly 30 active users on it. I personally know everyone using the server. Recently, a few friends and I were working on project. We made a new directory for the project and since everyone knows everyone we didn't bother protecting our work under a bunch of permissions. We should have though, because we woke up this morning to find that someone removed our entire directory. Our work is backed up every night so it's really not a big deal to restore our work. However, we would like to find out who removed it so we can confront them. So far the best thing we've come up with for finding our culprit is checking everyone's bash history but this is long and tedious and chances are that if there was a malicious intent behind the directory removal that our culprit probably modified theirs to cover their tracks (or of course they might use a different shell). So, basically, what is the easiest and quickest way to find out who deleted a directory? Thanks in advance for your time.

• Unity calendar lens not showing events

  - by David_G

  I'm trying to get proper/useful calendar integration into Ubuntu 12.04. I have a Google Calendar (& account) and I want to be able to use this without opening the browser. I want to get the Unity Calendar lens working, so that it shows events coming up, and it allows me a quick way to add new events. However, after installing it, it does not find any events, nor allow me to add a new event. Note that I've installed Lightning 1.4, Evolution mirror 0.2.3, Evolution, and unity-calendar lens. I've also installed Calendar-indicator. I suspect that somehow the lens is not getting the calendar information from thunderbird via evolution. A bit of searching around led me to try this command: /usr/lib/calendar-lens/calendar-lens-daemon.py. With this result: /usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed import gobject._gobject Traceback (most recent call last): File "/usr/lib/calendar-lens/calendar-lens-daemon.py", line 324, in daemon = Daemon() File "/usr/lib/calendar-lens/calendar-lens-daemon.py", line 80, in init for calendar in evolution.ecal.list_calendars(): AttributeError: 'NoneType' object has no attribute 'list_calendars' Any ideas?

• Where to find and install ASUS motherboard drivers for Linux

  - by Dan

  This is my second day ever with Linux, and I had one heck of a time getting the nVidia drivers installed and working. Please, keep in mind I am very new and just starting out. I currently have an ASUS P8Z68-V LE motherboard and I'm not sure if the drivers are installed. Where would I go to find that out? I am using Gnome as my UI. If I don't have the drivers installed, where would I go? The ASUS site only gives me options to download for various Windows OS, DOS and "other" (in .ROM format). Which should I take and how should I install? I'm mostly looking for audio drivers. A lot of music I play, either on YouTube or with VLC has a faint crackling in the background on Ubuntu, which gets much worse the higher I turn the volume up. Could this be something other than the drivers? I doubt it's the hardware since the sound seems fine on Windows. I am currently running 12.04.

• How to solve 'Connection refused' errors in SSH connection?

  - by frbry

  I have an Ubuntu Server 10.10 32-bit in my home. I'm making SSH connections to it from my PC via Putty. The problem is, sometimes I'm able to login seamlessly. However, sometimes it gives me an error like this: Network error: Connection refused. Then, I dont't change anything, try to login a few times more, wait a while and try again. Sometimes I can log in, sometimes I cannot. It seems pretty random to me. What can I do to solve this? Edit: And Sometimes, Putty gives Network error: Software caused connection abort error after displaying login as: text. Here is the ping -t output: Pinging 192.168.2.254 with 32 bytes of data: Reply from 192.168.2.254: bytes=32 time=6ms TTL=64 Reply from 192.168.2.254: bytes=32 time=65ms TTL=6 Reply from 192.168.2.254: bytes=32 time=88ms TTL=6 Reply from 192.168.2.254: bytes=32 time=1ms TTL=64 Reply from 192.168.2.254: bytes=32 time=3ms TTL=64 Reply from 192.168.2.254: bytes=32 time=1ms TTL=64 Reply from 192.168.2.254: bytes=32 time=1ms TTL=64 Reply from 192.168.2.254: bytes=32 time=1ms TTL=64 Reply from 192.168.2.254: bytes=32 time=1ms TTL=64

• Gimpshop 2.8. Available for Win & Mac. No Linux version?

  - by Jorge M. Treviño

  Finally got around to upgrading 12.04 to 12.10. One of the nice things about the new version is that Gimp 2.8 is in the repositories. Installed and it's a far cry from the 2.2, 2.4 and 2.6 versions which were —at least from my untrained point of view– next to unusable. Now 2.8 is a much more intuitive, for Photoshop users at least, and I'm trying to really learn it. Browsing around, I found that there's s new version of Gimpshop, something that was a sorely amateurish attempt to a PS interface over an old Gimp version and sure to mess up your system. Seeing "2.8" prominently displayed in the page, I decided to try the Windows version. Oddly, there's a Mac version too but no Linux one. The link directs one to a non-existent file in one of the cloud storage sites. After the Win version was installed, I fired it up and, surprise!, it's exactly the same as I can tell without diving into menus and dialogs, as the plain vanilla Ubuntu version I have installed. Can anybody shed light on what goes on here? Is this a scheme to get inadvertent users to install some "optional extras" that come with the installer? Very curious about it (thanks God I'm not a cat ).

• How can I get something like Nautilus's "spatial" behaviour in 11.10 and later?

  - by Dylan McCall

  Until recently, Nautilus had an optional "spatial" mode as an alternative to its usual browser mode. Users could enable it by opening Nautilus's preferences and selecting "Open each folder in its own window." Choosing this option resulted in a stripped down interface, and folders would always open in the same place on the screen. It looked something like this: That checkbox is still there, but it doesn't do the same thing: while every folder opens in a new window, those windows are all the same size and positioned the same way. Nautilus doesn't restore the size and position of each folder, which is what spatial mode was all about. This difference really shows if someone opens a folder in a new window, and then opens the same folder again. Nautilus will create another window instead of focusing the existing window. I help someone who is currently using Ubuntu 10.04, and he will be upgrading to 12.04 in the future. He is very comfortable with Nautilus's spatial behaviour and I think he would be disappointed to lose it. Is there an alternative file manager, or perhaps some less obvious option, that will give him an interface similar to the one he is comfortable with?

• How to distribute python GTK applications?

  - by Nik

  This is in correlation with the previous question I asked here. My aim is to create and package an application for easy installation in Ubuntu and other debian distributions. I understand that the best way to do this is by creating .deb file with which users can easily install my application on their system. However, I would also like to make sure my application is available in multiple languages. This is why I raised the question before which you can read here. In the answers that were provided, I was asked to use disutils for my packaging. I am however missing the bigger picture here. Why is there a need to include a setup.py file when I distribute my application in .deb format? My purpose is to ensure that users do not need to perform python setup.py to install my application but rather just click on the .deb file. I already know how to create a deb file from the excellent tutorial available here. It clearly shows how to edit rules, changelog and everything required to create a clean deb file. You can look at my application source code and folder structure at Github if it helps you better understand my situation. Please note I have glanced through the official python documentation found here. But I am hoping that I would get an answer which would help even a lame man understand since my knowledge is pretty poor in this regard.
