  • QML: Overriding a signal handler from other element

    - by user3490458
    Is it possible to override an elements action (eg onTriggered() of a Timer) from within the onClick() of a button? Something like so- Button { id: centerBtn objectName: "button" onClicked: { delaytimer.running = true; delayTimer.onTriggered {}; // override here } Timer { id: delaytimer interval: 1000 running: false repeat: false onTriggered: //something implemented here } }

  • Limit the size of a directory by deleting old files

    - by Sulliwane
    I have a IP cam which save its recordings in a specific directory named Camera1 in my Ubuntu Server 12.04. I would like to limit the size of this folder to 5 gigs, by deleting -say once a day- the oldest files. I first checked the quota program but it doesn't seem to allow the creation of new files and deleting of the old ones. So I think the best workaround would be to run a bash script ? But I have no idea how to write it... Thank you guys !

  • Grub errors during UEFI dual boot for Windows 8 (can't find command 'drivemap')

    - by luca-mastro
    I have got a newly bought ASUS N56V with Windows 8 preinstalled. I needed to install Ubuntu so i partitioned the disk and after having disabled the Secure Boot option from Windows 8 i successfully installed Ubuntu 12.10 from a Live USB. The problem is that if i try to access both to Windows 8 (loader) and Windows Recovery System (loader) from the GRUB menu, these two errors show: can't find command 'drivemap' and invalid EFI file path and it goes back to the grub menu. In conclusion I do not have access to my Windows 8 partition but can only use Ubuntu. How can I solve the problem? I am pretty new to the matter. Thank you!

  • Google locking on Ubuntu

    - by user170534
    Problem I'm facing is that Google doesn't respond well timed to connection requests send from any browsers known to Linux. As far as I can tell, this was existent in Mint, which is Ubuntu based. I have no debug or guess about cause but I'm sure there are people with the same problem. ping of terminal is untouched but any other browser keeps unloaded, for example; google loads fine, I search for something. Then I decide to search for something else and ta daa: You gotta wait for 30 seconds for Google server to respond. I tried using google's public DNS without success. Flare the suggestions & ideas!?

  • How to get rid of bookmarks in synced Chromium

    - by Lambda Dusk
    I'm using three Ubuntu systems in an irregular pattern, and since I use Chrome/Chromium anyway and have a Google account, I decided to make my life a bit easier and sync them. Now I am having a problem: When I want to remove bookmarks from my lists, they not only come back when I switch the machine, they double. By now, I have up to ten identical bookmarks in the list and I spend a lot of time scrolling over them. Is there any way to remove them permanently? EDIT: Apps, too.

  • Newbie tips, please [closed]

    - by eXeP
    So, I just got a new computer and I want to put Ubuntu on my old laptop. I just need few tips before installing it. 1.Programs, where to download, how to download, what is the "ending" (windows has .exe) 2. How much is command line involved? And where to get the most usual commands? 3.Few programs you recommend (graphics editing, IDE, video player, web browser) 4. Do I have to download drivers when installing new OS? I plan on getting fully rid of Windows. I have no idea of the name of my graphics card, so how do I can get to know what it is if I have to download drivers? (I don't know the name because it's not on the original box, or anywhere on the internet, believe me) 5. When installing new OS does it destroy everything else on the hard drive? 6. Anti-virus, do I need one? I'm not super paranoid, and I don't visit "shady" sites. Please note that I have never used linux, or any other OS than Windows and sorry for my bad english. If this is the wrong place to post this, then please remove this. Thank you.

  • Teminal hands on load, can't enter anything until CTRL+C

    Hello! I have an issue with terminal in Ubuntu 10.04. When I launch it, it hangs, like this: I cannot do anything until I press CTRL+C: I cannot remember when this started. What can be wrong?

  • Is it worth upgrading Ubuntu 10.04 to 12.04? [closed]

    - by Ariel
    A few years ago, I used Ubuntu 10.04, and i liked it a lot. It never crashed. Then I have to change to Win*** because of work. But this year, I heard about Ubuntu 12.04 and I wanted to install it. I've done this, but I have a lot of crashes. I don't do something special to make ubuntu crash, but sometimes it shows me a crash message. So, is it worth migrating to 12.04? Do somebody stay with the 10.04? I really want to use ubuntu, and I will, but I don't know if it worth to use the newest release or with the 10.04. If i install the 10.04 version, ubuntu tells me all the time to upgrade to the new version? Or will I use it fine? What do you suggest me? Thanks everybody for your time, and sorry for my english.

  • Sudo Non-Password access to /sys/power/state

    - by John
    On my computer, pm-hibernate appears to be broken, however using the command echo disk > /sys/power/state appears to work perfectly. Now I just need regular user access to it, using sudo. How do I do this? The command sudo echo disk > /sys/power/state simply returns bash: /sys/power/state: Permission denied. Also, I need this in a regularly used script, how can I make it so that I don't have to type in my password for it to work???

  • forward sudo verification

    - by Timo Kluck
    I often use the following construct for building and installing a tarball: sudo -v && make && sudo make install which will allow me to enter my password immediately and have everything done unattended. This works well except in the rare case that building takes longer than the sudo timeout, which may happen on my rather slow machine with large projects (even when using make -j4). But when the build takes a long time, that's exactly when doing things unattended has a great advantage. Can anyone think of a shell construct that allows me to input my password immediately, and which has make executing under normal permissions and make install under elevated permissions? For security reasons, I don't want to configure my user to use sudo without password. A viable option is to set the timeout to very long, but I'm hoping for something more elegant.

  • Why doesn't Ubuntu nvidia-current support the later proprietary drivers for LTS releases?

    - by keepitsimpleengineer
    e.g. in my Lucid 10.04 LTS system I had to uninstall the ubuntu proprietary drivers and manually install drivers from nvidia.com for an upgraded video adapter to get the system to work.

  • delete /var/cache/* How can I fix it?

    - by user110474
    I accidentally remove all files in /var/cache/ directory with sudo rm -rf command. Now I can not see the files in Trash to bring them back. I would like to know how bad is the situation if these files are removed? does ubuntu going to work normally and recreate the directories in cache again automatically? If not, which directories do I have to create in /var/cache/ manually to let everything work fine? I have already manually made apt and apache2 and debconf in cache directoy but I do not know if I miss more importand directory which needed to be created there. I hope somebody can guide me to fix this issue.

  • How do I "print" to a PostScript file from LibreOffice Write?

    - by user69245
    Using OpenOffice with 10.04 I was able to print to a Postscript file, but I find I can't do this with LibreOffice and 12.04 - print-to-file goes to PDF. I want this feature so that I can use a FinePrint-like tool called fprint to print .PS files in booklet form. When I print from other applications I'm offered the usual choice of printers, including print to .PS, but LibreOffice restricts my choice.

  • Media Drive Permissions

    - by Wade Wofford
    I just switched from a Hackintosh to Linux, and am trying to make sense of it. On my hackintosh, I partitioned a big drive into 3 parts--1 which holds music, 1 for film/tv, and one for the OS. I installed Ubuntu onto the OS partition, and am now trying to make it so I can write to the media drives. I've searched around and tried several things. I tried gksu nautilus in Terminal, which brought me into root permissions. When I select a folder and try to change permissions, I get "The owner could not be changed...Error setting owner: Read-only file system" Ultimately, I have two specific aims: - I want to make it so I can write to the film/tv drive from the ubuntu machine only - I want to make it so I can write to the music drive from the ubuntu machine, or any other machine on the network (all Macs). That is, I want a single music library (an iTunes file) that will serve all Mac laptops/iPads/iPhones on the network, but which XBMC on the Ubuntu machine can also see / read from. Music will be added to the iTunes library via a single Mac laptop, but all other devices should be able to see the music drive.

  • GWT (Google Web Toolkit) Designer not working on Ubuntu 12.10

    - by Marian Lux
    The GWT Desinger is not working on Ubuntu 12.10. It worked on Ubuntu 12.04. I installed the Eclipse Plugin as described on the GWT Homepate If I want to open the Design-View (for an xml-GWT-File), Eclipse crashes (prompt closing of the application). I found this two workarounds for which are for 12.04 (but on 12.04 i did not need this to get it working - it worked out of the box for me). I tried them on my 12.10 Ubuntu but they are not working. But I have to say that I can't find the "Use WebKit for rendering GWT UI (if available)"-Flag. What can I do to get the GWT Designer working? I tested it successfully again on a 12.04 Ubuntu VMware image. If I don't get a solution, I have to downgrade my Ubuntu to 12.04 again.

  • unzip error "End-of-central-directory signature not found"

    - by Tim
    I try to unzip a zip file, but got an error: $ unzip COCR2_100.zip Archive: COCR2_100.zip End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. note: COCR2_100.zip may be a plain executable, not an archive unzip: cannot find zipfile directory in one of COCR2_100.zip or COCR2_100.zip.zip, and cannot find COCR2_100.zip.ZIP, period. I googled but didn't find a solution. I was wondering why it is and how I should fix it? Thanks! The zip file can be downloaded from COCR2_100. It is an application, and here is its website http://users.belgacom.net/chardic/cocr2.html. My OS is 10.10.

  • Synonyms for different languages in LibreOffice Writer? [closed]

    - by cipricus
    Possible Duplicate: How do I add English-UK thesaurus in LibreOffice? When setting a text for English US the context menu contains 'Synonyms' This is not the case for the other languages for which I have the spelling installed (English UK, French etc) Can I have the Synonyms option for UK English too, for example? Even that is a problem although there seems to be solutions around for it. Here, for example, (which is a link to here) but after testing it cannot see synonyms for uk. Also this which was reported as a solution is not working anymore it seems. What about other languages? (Please notice that this question is not just about English-UK. I have initially noticed that 'synonyms' where missing in relation to British, but I am asking about how to solve the issue in general or, when there is no general solution, how to solve it on a case-by-case basis. For the meta consequence of all this, involving the issue of it being a duplicate, see comments under here and this question.)
