• Can I use standard tools to get the full name of a process, when its name has embedded spaces?

  - by fred.bear

  I understand that it may be a rare situation for an executable to have spaces in it, but it could happen. An example may be the best explanation.. Using standard tools, I want to determine the location (on the file system) of the executable which owns(?) the current window... get the current window ID ...(xdotool getactivewindow ) use the ID to get the PID ...(wmctrl -p -l | sed ... ID .... use the PID to get the executable's name ... (ps -A ... here is where I run into problems ! Whith ps, when listing only the executable's name (-o ucmd), it truncates the name to 15 characters, so this rules out this option for any name which is longer. Widening the column (-o ucmd:99 ) makes no difference.. If pgrep is anything to go by, its matching is limited to 15 because of stat (see: info pgrep).. Listings in variants of "full" mode (eg -A w w) are not useful when the name concerned has spaces in it, because this name is separated from its args by another space!.. Also, in "full" mode, if the process was started by a link, the name of the link is shown, rather than the executable's name. Is there some way to do this (using standard tools)? ...or are spaces a show stopper here?

• How can I select which Java to use?

  - by user6611

  I have installed both OpenJDK 6 and 7. When I run "java somefile" from the command line, OpenJDK 6 is invoked. I do not want to change this default behavior. What command can I use to run my non-default OpenJDK 7 installation instead? (I am used to running "python somefile" to invoke the default Python, "python2.7 somefile" to use Python 2.7 specifically and "python3 somefile" to use Python 3 specifically.)

• How do I add more than one command to /etc/rc.local?

  - by Andreas

  I want to add two power saving commands to /etc/rc.local file. This to dissable bluetooth: rfkill block bluetooth And this to reduce screen brightness: echo 3024 > /sys/class/backlight/intel_backlight/brightness Separately added to /etc/rc.local they work but not both of them together like this: #/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. echo 3024 > /sys/class/backlight/intel_backlight/brightness rfkill block bluetooth exit 0 How do I add the two commands to get them properly executed at start-up? Update It turned out to be a timing issue. I fixed it by delaying the execution of the first command thus: (sleep 5; echo 3021 > /sys/class/backlight/intel_backlight/brightness)&

• Why are Back In Time snapshots so large?

  - by Chethan S.

  I just backed up the contents of my home partition onto my external hard drive using Back In Time. I browsed to the backed up contents in the external drive and under properties it showed me the size as 9.6 GB. As I read that in next snapshots I create, Back In Time does not backup everything but creates hard links for older contents and saves newer contents, I wanted to test it. So I copied two small files into my home partition and ran 'Take Snapshot' again. The operation completed within a minute - first it checked previous snapshot, assessed the changes, detected two new files and synced them. After this when I browsed to the backed up contents, I was surprised to see the newer and older backup taking up 9.6 GB each. Isn't this a waste of hard drive space? Or did I interpret something wrongly?

• How to reset the language of the package descriptions

  - by xubuntix

  I have had German as my main language about a year ago. Later I changed it to English. Most parts of the system accepted the change. The notable exceptions are the package descriptions, which remain in German for some packages. You can see in the image (apt-cache and software-center), that while some descriptions are in English, some have remained in German. So the question is: how do I reset this? I guess that there is somewhere a description cache that needs to be told that it should update all descriptions? EDIT: As asked: the output of some language related commands: $ cat /etc/default/locale LANG="en_US.UTF-8" $ apt-config dump | grep Lang Acquire::Languages ""; Acquire::Languages:: "de_DE"; Acquire::Languages:: "de"; Acquire::Languages:: "en"; Acquire::Languages:: "none"; $ locale LANG=de_DE.UTF-8 LANGUAGE=en LC_CTYPE="de_DE.UTF-8" LC_NUMERIC="de_DE.UTF-8" LC_TIME="de_DE.UTF-8" LC_COLLATE="de_DE.UTF-8" LC_MONETARY="de_DE.UTF-8" LC_MESSAGES="de_DE.UTF-8" LC_PAPER="de_DE.UTF-8" LC_NAME="de_DE.UTF-8" LC_ADDRESS="de_DE.UTF-8" LC_TELEPHONE="de_DE.UTF-8" LC_MEASUREMENT="de_DE.UTF-8" LC_IDENTIFICATION="de_DE.UTF-8" LC_ALL= As a note: I'm not sure what each entry means, but some of the de_DE.UTF-8 are probably ok, since I do want paper-sizes, monetary, time, etc. in standard German formats.

• Touchpad stopped working out of the blue

  - by KI4JGT

  So, I'm watching "The Walking Dead" and all of the sudden I lose control of my mouse through the touchpad. At first it was just for my user. I could reboot my system and switch to another user and use it just fine. I cannot explain the steps I took (I'm using the keyboard to manuver firefox right now) but it was something along the lines of: sudo modprobe -r psmouse && sudo modprobe psmouse proto=imps After this command, I regained control of my mouse but the computer didn't recognize it as a touchpad. I thought if I rebooted again, it may do the trick. So after I rebooted, the mouse went completely kaput. I cannot get the mouse to work at all now even though I've tried the command several times. I've tried different users and it's still the same.

• How to fix additional STA driver installation error on 12.04

  - by nibl

  I have a Broadcom BCM4313 wireless driver. It worked fine under 11.04 and the upgrade to 11.10 also went smoothly. The 12.04 upgrade has broken the wireless connection. I've seen several posts about this and all presume you can activate the STA drivers, but that's where it fails on this machine. The log is in /var/log/jockey.log: WARNING: modinfo for module wl failed: ERROR: modinfo: could not find module wl WARNING: /sys/module/wl/drivers does not exist, cannot rebind wl driver DEBUG: BroadcomWLHandler enabled(): kmod disabled, bcm43xx: blacklisted, b43: blacklisted, b43legacy: blacklisted (repeat of last error several times) Any ideas how to proceed?

• How can I connect my USB (HP) printer in 10.4, which can't be discovered and worked in 9.x

  - by Brian

  My printer was working under 9.x. It is a an hp photosmart C3100 series. When I open the Admin- printing. no local printers are found. I try to add via other (My local choices are Serial and other). I have tried many uri's - ipp://localhost:631/ipp, http://localhost/ipp, localhost, 127.0.0.1, etc... None have worked. Under the networked I have tried JetDirect, using localhost and 127.0.0.1 and port 631. I have tried many options under IPP with different variants in the host trying to verify a printer. No luck. I tried LPD/LPR with localhost and tried the probe. no luck. I tried the cups admin via localhost:631 and that didn't work. On the old version its simply found the local printer, I might have picked the driver, I can't remember but it was the photosmart c3100 series that was working. I just can't get 10.4 to print.

• can't update 12.04 getting package header error

  - by joel

  I originally posted this question, and was redirected to another thread where the question had already been asked. I then posted to that thread and had my post deleted by moderator fossfreedom, and told to post a "new" question... so wth ever.... I don't care if it's old or new I just need help here people! In a nutshell, I can't use sudo apt-get update or the GUI update tool to update my system. Anytime I try using either tool it gives me an error about packages missing headers. I can't send error reports, I have tried all the listed solutions from this post: I can't update my system properly, "no package header" error and from this post: "Problem with MergeList" error when trying to do an update and neither one work. I just want a working solution since I don't have the means of re-installing the OS entirely, and I REALLY don't want to have to go back to using Windows.

• Can't find new.h - getting gcc-4.2 on Quantal?

  - by Suyo

  I've been trying to compile the Valve Source SDK (2007) on my machine, but I keep running into the same error: In file included from ../public/tier1/interface.h:50:0, from ../utils/serverplugin_sample/serverplugin_empty.cpp:13: ../public/tier0/platform.h:46:17: new.h: No such file or directory I'm pretty new to C++ coding and compiling, but using apt-file search I tried to use every single suggestion for the required files in the Makefile (libstdc++.a and libgcc_eh.a), and none worked. I then found a note in the Makefile saying gcc 4.2.2 is recommended - I assume the older code won't work with the newer version, but gcc-4.2 is unavailable in 12.10. So my question/s is/are: If my assumption is right - how do I get gcc 4.2.2 on Quantal? If my assumption is wrong - what else could be the problem here?

• Pinning ipython3 qtconlsole to launcher

  - by phg

  I've installed both ipython (which uses Python 2.7) and ipython3, and the respective qtconsole packages. Both work when I call them from the terminal like ipython qtconsole. However, when I search for them in the dash home, only the 2.7 versions (of both the shell and qtconsole) appear, as executables. Searching for ipython3 only yields the ipython3 file from /usr/bin. Changing to the "application lens" doesn't affect the results. Also, even if I can start both from the terminal, I can only pin the running 2.7 version to the launcher -- or, to be more exact, I can pin the v3 console, but the icon looks somehow blurred, and it doesn't start anything when I click it. So, whats happening here? Is the v3 package hidden somehow?

• How to make read-only file system writable?

  - by Tim

  I am not sure since when the filesystem on my digital audio player has been changed to be read-only. I cannot copy files into it or remove files on it. Are there some possible reasons for the player's file system to change the permission of its file system? I tried chmod: $ sudo chmod a+rw SGTL\ MSCN/ chomd: changing permissions of `SGTL MSCN/': Read-only file system where "SGTL MSCN" is the mounted point of the digital audio player. I was wondering how to make it writable? Thanks and regards!

• totally stuck trying to SSHing remote server

  - by user9609

  Hey guys, So i've been given access to ssh a server. I have the username/password, but server apparently requires a public key (now bear in mind that i am a noob in ssh). When I do: ssh -p 52 [email protected] terminal says Permission denied (publickey). So I went using ssh-keygen -t rsa and got myself the id_rsa and id_rsa.pub files in /root/.ssh. Chmoded /root/.ssh to 700 and /root/.ssh/* to 600. Tried sshing server.com again, same error. What am I missing? I've been given a Putty Pagant Key file (.ppk) by the SYSADMIN of server.com. Apparently, other users (all Windows) can connect using Putty Pagant.exe. Please help :)

• Why isn't .profile sourced on login to LXDE?

  - by papukaija

  I switched recently from GNOME to LXDE and since then my .profile file hasn't been sourced on login. I found out that my PATH variable doesn't include ~/bin anymore. However, my .profile file includes PATH="$HOME/bin:$PATH" while PATH's content is /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games. Is it intended that LXDE doesn't read this file on login? If yes, what file should I use to add the bin folder to the PATH variable? If not, to what package should I report a bug?

• Zotero error in libreoffice

  - by arno

  I installed Zotero standalone in 12.10 64bit. Some problems which I managed to fix. The one that remains is an error saying "openoffice.org could not communicate with Zotero. make sure zotero standalone or Firefox are open and set to an online state and try again". That's when I click any button in the Zotero toolbar in libreoffice. Firefox doesn't open with a the plugin installed and a working internet connection. The Zotero troubleshooting which mentions this error was of no help to me. I find reports about this bug going back as far as 2009 but I haven't found anything of help.

  I have dual boot config with kubuntu 12.04 and Windows7. My problem started this morning when I tried to boot kubuntu. Everything worked fine a couple of days ago and I have not done any mayor system configurations since then. Choosing kubuntu options from grub gives me this screen A couple of minutes later this screen is shown And then it gets stuck. Have been waiting for ~5mins without anything happening. I have tried running fsck from recovery menu without any errors. I have also tried booting in failsafex mode which gives me "Fatal server error: no screens found". apt-get update gives me "Duplicate sources.list entry". I have also tried fixing broken packages from recovery menu. What should I do next?

• How to remove all associated files and configuration settings of an app installed through 'force architecture' command

  - by Mysterio

  A few weeks ago I installed a 32 bit .deb file through the 'force architecture' command (on my 64bit notebook), however the procedure was unsuccessful and I used the apt-get purgecommand to uninstall the app. It seems there are some leftovers of the app I uninstalled which has now broken system update. Synaptic recommended a sudo apt-get install -fwhich I did in the terminal with this initial response: Reading package lists... Done Building dependency tree Reading state information... Done The following package was automatically installed and is no longer required: libntfs10 Use 'apt-get autoremove' to remove them. The following packages will be REMOVED: crossplatformui 0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded. 1 not fully installed or removed. After this operation, 0 B of additional disk space will be used. Do you want to continue [Y/n]?
