  • Unable to change the launcher icon size

    - by takeshin
    After upgrading to 11.10 I can't change the launcher icon size to smaller. I've tried to change it using ccsm, like described in How can I configure Unity, but the changes take no effects (restarted, tried sudo - still big icons). In the previous version of Ubuntu this solution worked. How can I change the icon size? (BTW, how can I know which Unity (2D vd 3D) I'm running and switch between?). Edit: Looks like I'm using Unity 2D and have some problems with graphics: me@my-laptop ~ $ /usr/lib/nux/unity_support_test -p Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0".

  • How did Ubuntu know my WPA Key?

    - by nebukadnezzar
    I've recently moved my /home to another computer (keeping all configuration files), with a fresh installation of Ubuntu 10.10. After Installation I've installed wicd and ndiswrapper, to get my Internet Connection up and running. However, after changing /etc/network/interfaces from auto lo iface lo inet loopback To auto wlan0 iface wlan0 inet dhcp and running sudo /etc/init.d/networking restart to get wlan0 set up, wicd just suddenly connected... to my modem. Without supplying any information about the modem whatsoever. Of course wicd creates a local directory at ~/.wicd/, but that directory is empty, and the temporary global configuration at /var/lib/wicd/configurations/ didn't exist due to fresh installation of ubuntu. So what's the deal? Where did wicd get the ESSID and the WPA Key? There hasn't been any activity in this question, but it's still open (and even worth some rep)!

  • Including slick2d or slick-util in maven build?

    - by BotskoNet
    I'm converting a project to lwjgl and trying to use slick-util as well. There's no slick-util maven repo anywhere (nor slick2d itself anymore). I've included local dependancies before using <dependency> <groupId>org.newdawn</groupId> <artifactId>slick</artifactId> <version>237</version> <scope>system</scope> <systemPath>${project.basedir}/lib/slick-util.jar</systemPath> </dependency> The maven package process runs without issue, but when I try to run the jar, it errors out with a ClassNotFoundException. There's no mention of slick-util in the manifest and I can't find out how to make my game load that jar properly. Side question: how do I ensure when I distribute my applications, the game properly installs these libraries?

  • Jupiter seems to break multimonitor setup

    - by Philippe
    If Jupiter is in the startup my multimonitor setup will fail. Instead of two separate desktops the monitors will be mirrored, one over the other with the smaller notebook-desktop in the larger screen: After each new log-in I have to reset the Display settings in the "System Settings..." dialogue to two not mirrored screens, the changes don't seem to be saved. Given the the entry from xsession-errors /usr/lib/jupiter/scripts/resolutions: line 42: /var/jupiter/available_resolutions_LVDS: Permission denied I assumed that it's coming from Jupiter. Infact, if Jupiter is removed as startup application the desktop settings are fine. Any idea how to solve that issue?

  • How do I recover from upgrading while using bad version of gcc/binutils?

    - by Shawn J. Goff
    I upgraded from 9.04 to 10.10 a couple of days ago, and things are really messed up - X is crashing constantly. Since then, I had an application segfault for no reason, when I was debugging, I found that it was strlen() that was causing the segfault (pointing to libc being the problem)! Upon investigation, I found that it was because I had a bad version of gcc and binutils installed in /usr/bin/local; I removed it, recompiled the application, and it no longer crashes. Now, looking at my logs, I see that X is also crashing due to libc. Backtrace: 0: /usr/bin/X11/X (xorg_backtrace+0x3b) [0x80ef31b] 1: /usr/bin/X11/X (0x8048000+0x5d00d) [0x80a500d] 2: (vdso) (__kernel_rt_sigreturn+0x0) [0xb77e240c] 3: /usr/bin/X11/X (0x8048000+0xbb0b6) [0x81030b6] 4: /usr/bin/X11/X (0x8048000+0xbc3ef) [0x81043ef] 5: /usr/bin/X11/X (0x8048000+0x26ee7) [0x806eee7] 6: /usr/bin/X11/X (0x8048000+0x1a5da) [0x80625da] 7: /lib/libc.so.6 (__libc_start_main+0xe7) [0xb750ace7] 8: /usr/bin/X11/X (0x8048000+0x1a1b1) [0x80621b1] Segmentation fault at address 0x32156654 Caught signal 11 (Segmentation fault).

  • How can I make the Ubuntu Software Center load?

    - by Kieran
    I launch it and it goes grey for almost immediately. Closing it prompts me to "force close" and no error report is given. I launched it in Terminal and this was the resulting log: 2012-11-23 22:39:25,175 - softwarecenter.ui.gtk3.app - INFO - setting up proxy 'None' 2012-11-23 22:39:25,179 - softwarecenter.db.database - INFO - open() database: path=None use_axi=True use_agent=True 2012-11-23 22:39:25,409 - softwarecenter.backend.reviews - WARNING - Could not get usefulness from server, no username in config file 2012-11-23 22:39:25,412 - softwarecenter.fixme - WARNING - logs to the root logger: '('/usr/lib/python2.7/dist-packages/gi/importer.py', 51, 'find_module')' 2012-11-23 22:39:25,412 - root - ERROR - Could not find any typelib for LaunchpadIntegration 2012-11-23 22:39:25,474 - softwarecenter.ui.gtk3.app - INFO - show_available_packages: search_text is '', app is None

  • Problem upgrading from 13.04 to 13.10

    - by Charles
    Part way through upgrading from 13.04 to 13.10 the process ground to a halt with an error message. Now on retrying by going to 'Check for updates' I get the following: Failed to load the package list This is a serious problem. Try again later. If this problem appears again, please report an error to the developers. E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_saucy_universe_i18n_Translation-en%%5fGB, E:The package lists or status file could not be parsed or opened. Problem reported but my question is, "what can I do now?; Do I have to do a fresh install?; if so will settings etc. in my Home folder (on its own partition) be saved?" 13.04 still seems to be working perfectly, while upgrading I had a terrible internet connection varying between 'dead slow' and 'dead stop', not sure if that caused the problem.

  • OpenOffice doesn't work

    - by dn.usenet
    I installed OpenOffice on 12.04, and set it as the default utility for spreadsheets, but it doesn't run at all. While trying to troubleshoot, I read that it is not recommended to install it alongside LibreOffice. I am about to uninstall OpenOffice because I don't know how to get it working, and LibreOffice is opening my spreadsheet just fine. But just out of curiosity, I also read that I should try deleting .openoffice.org folder; but from where? I don't see it under /usr/lib, nor under my /home.

  • What does intermittent "Input/output error" suggest?

    - by dan
    Lately my Ubuntu 12 system has started acting very strange. Sometimes the computer freezes and then unfreezes 2 minutes later, and other times when I try a basic command like less I get the error bash: /usr/bin/less: Input/output error. But this is intermittent too. Any suggestions? Also if I try sudo reboot and enter my password, I get sudo: unable to open /var/lib/sudo/plato/7: Read-only file system Before I used to be able to do sudo reboot fine. If I tail /var/log/syslog I do see these curious lines: .... ata1: softreset failed (device not ready) .... ata1: hard resettting link .... ata1: link is slow to respond, please be patient (ready=0) What can I do to fix this?

  • How could there still not be a mysqldb module for Python 3?

    - by itsadok
    This SO question is now more than two years old. MySQL is an incredibly popular database engine, Python is an incredibly popular programming language, and Python 3 has been officially released two years ago, and was available even before that. What's more, the whole mysqldb module is just a layer translating Python's db-api to MySQL's API. It's not that big of a library. I must be missing something here. How come almost* nobody in the entire open source community has spent the (I'm guessing) two weeks it takes to port this lib? Is Python 3 that unpopular? Is the combination of python and mysql not as common as I assume? Or maybe it's just a lot harder to port mysqldb than I assume? Anyone know the inside story on this? * Now I see that this guy has done it, which takes some of the wind out of my question, but it still seems to little and too late to make sense.

  • Installation of Ubuntu 13.04 seems to take forever

    - by Michel
    I am about to install Ubuntu 13.04 on my AMD x64 machine and the installation of the lib packages seems to take forever. Is that a known issue? I know that it might take some time when checking to download packages from the Internet but this went through very fast. In the terminal-like view I can see, the system is just unpacking, installing, configuring etc. in a quite slow way. In the opening screen it reads: It just takes a few minutes (or something close to that). Again: Is that a normal behavior or am I doing something wrong and what could I do to speed up the process in case I'm running an installation again on another system?

  • Seeking some advice on pursuing MS in CS from Stanford or Carnegie Mellon or Caltech

    - by avi
    What kinds of projects are given preference in top notch colleges like Stanford, Caltech, etc to get admission into MS programme in Computer Science? I have an average academic portfolio. I'm pursuing Btech from a not so popular university in India with an aggregate of 67%. I'm good at designing algorithms and possess good knowledge of core subjects but helpless with my percentage. So, I think the only way I can impress them is with my project(s). Can anyone please suggest me the kinds of projects that are given preference by such top level institutes? Could you please also suggest some good projects? My area of interest would be Artificial Intelligence or any application/software/algorithm design which could be of some help to common people. Or if you have any other random idea for my project then please share it with me. Note: Web based projects and management projects like lib management wouldn't be my priority.

  • I want a non admin user to install software. What commands do I need to add to sudoers?

    - by Chance
    I want to edit the /etc/sudoers file so that a non-admin user can install software via the Software Center in Linux Mint 10. The reason for this is that I want a user to have the capability to install programs, but not make any other configuration changes to the system. So far I have the following (some of these may not make sense, I was just trying whatever I thought of) username ALL= /usr/bin/aptitude username ALL= /usr/bin/dpkg username ALL= /usr/local/bin/apt-get username ALL= /usr/lib/linuxmint/mintUpdate/mintUpdate.py username ALL= /usr/bin/software-center username ALL= /usr/bin/synaptic So far, it allows me to do updates without asking for my password, but it will not let me install software without entering an admin password. I am aware of this question, How can I set the Software Center to install software for non-root users?, but this goes the route of modifying the PolicyKit, whereas I'm interested in a sudo solution, because it seems a simpler way to go.

  • API Design Techniques

    - by Dehumanizer
    Is it right or more beautiful to name the functions with an prefix, like in Qt? Or using "many" namespaces, but 'normal' names for functions? For example, slOpenFile(); //"sl" means "some lib" vs some_lib::file_functions::openFile(); UPD: I've read somewhere that the first variant(using some prefix) is better, because the API users can perform 'fast' search among the documentation and in the Internet. E.g. by typing the magic prefix search engine starts to advice the exact functions. Is it enough to use the first variant?

  • Preventing pop-up dialogs when connecting an MTP device

    - by DrownedSensors
    I'm using Lubuntu 14.04 with a Samsung Galaxy S3 running Android 4.3. Each time I connect my phone via USB, I get the following dialog: Unable to open MTP device '[usb:002,023]' A few moments later, I get the "Removable medium is inserted" dialog, prompting me to open in File Manager. After that, the phone is connected and fully accessible. So MTP works. The problem is that I plug in my phone to charge every time I sit down, and unplug it every time I step away. Dismissing these two dialogs every time is a pain. I would think the "Removable medium" dialog is the easier candidate. How do I tell Ubuntu to take no action and stop prompting me? For the MTP error, all the discussion I can find is for people who can't get MTP working at all. For me, it's working, but only after throwing this initial error. I've verified that my device is present in /lib/udev/rules.d/69-libmtp.rules

  • Why UFW has to be (re)started at boot time if it's only iptables rule manager?

    - by Tomasz Zielinski
    README from source package says: When installing ufw from source, you will also need to integrate it into your boot process for the firewall to start when you restart your system. Depending on your needs, this can be as simple as adding the following to a startup script (eg rc.local for systems that use it): # /lib/ufw/ufw-init start For systems that use SysV initscripts, an example script is provided in doc/initscript.example. See doc/upstart.example for an Upstart example. Consult your distribution's documentation for the proper way to modify your boot process. On my system I have this: # /etc/ufw/ufw.conf # # Set to yes to start on boot. If setting this remotely, be sure to add a rule # to allow your remote connection before starting ufw. Eg: 'ufw allow 22/tcp' ENABLED=yes So, why does simple iptables rule manager need to be started at boot time? Is there any secret to that, or it merely checks if all rules are in place ?

  • How do I figure out which version of OpenCL comes with my nvidia-current-dev package?

    - by levesque
    I am running Ubuntu 10.04 with an nvidia geforce GT 240 card. I installed nvidia-current-dev with apt-get, thus I got a bunch of headers and lib files for OpenCL. However, I am unable to figure out if I have OpenCL 1.0 or 1.1 (could be 1.2, though I doubt it). Does anyone know a way to figure out which version of OpenCL comes with the nvidia-current-dev package (version: 195.36.24-0ubuntu1~10.04.2)? If not, is there another place where I could get an answer?
