  • keyboard shortcut to switch focus between separate X screens?

    - by ang mo
    I'm using XFCE on a dual monitor setup, with Xorg configured to separate X screens (neither twinview nor cinerama is working on GF470 with latest nvidia drivers). I'm not using xrandr. Suppose I have firefox running on one screen (:0.0) and thunderbird on the other (:0.1). When I want to switch focus from thunderbird to firefox, I need to move my mouse pointer to the firefox window and click (alt-tab switches between windows on a single screen only). Is there any keyboard shortcut for switching focus between screens?

  • How do I revert Alt-tab behavior to switch between windows on the current workspace?

    - by chris.ritsen
    Enabling Bias alt-tab sorting to prefer windows on the current viewport as described here made no difference. How can I get back the exact same behavior as 11.04, so that alt-tab only switches between windows on the current workspace? Simply disabling the alt-tab and shift-alt-tab keybindings on the unity switcher seems to have helped, but it still switches workspaces on me sometimes. For example, if I give a terminal window focus then press alt-tab, it switches to another terminal window on any workspace before trying to switch on the same workspace. Also, the Unity switcher still shows up when I alt-tab then hold alt even though I removed its alt-tab keybinding.

  • How to safely and painlessly switch from Kubuntu to Lubuntu?

    - by cdshines
    I've had Kubuntu installed for several years, updating from one major release to another, and now I think I'd like to try to switch to Lubuntu. But since my distribution is already tuned and shaped to satisfy my needs, I'd like not to get a fresh installation, but just purge kubuntu-desktop and install lubuntu-desktop. But when I execute sudo apt-get install lubuntu-desktop, it gives me an error of the following essence: The following packages have unmet dependencies: lubuntu-desktop : Depends: usb-modeswitch but it is not going to be installed E: Unable to correct problems, you have held broken packages. So, I investigate the modeswitch problem and get The following packages have unmet dependencies: usb-modeswitch : Depends: usb-modeswitch-data (>= 20110227-1~) but it is not going to be installed E: Unable to correct problems, you have held broken packages. But: Reading state information... Done usb-modeswitch-data is already the newest version. So, my question is: what actions should I take in order to obtain a clean and fresh installation of Lubuntu? And also, how do I safely remove all the kubuntu-desktop-related stuff?

  • Upgrade MySQL to 5.5 on Lucid, upgrade server to Precise or switch to Percona?

    - by xref
    Looking into upgrading mysql on our development server to which is running 10.04 so is stuck at MySQL 5.1, as it appears there is no apt-get support for upgrading to 5.5 except by certain 3rd party PPAs. So I'm looking for which route to take and what other people have done: a) Follow a couple year old guide to manually install MySQL 5.5 and then invest ongoing time into manually downloading and installing security updates every month or two? b) Upgrade 10.04 to 12.04, and from other peoples experience I work with spend several days working out the kinks of that large upgrade, then I'll have access to mysql 5.5 and easy apt-get installation of future security updates? c) Switch from MySQL to Percona Server 5.5 and get all the benefits of that version of mysql, plus easy apt-get updates with their PPA? d) Something else?

  • How to switch language spellingcheck on the fly when changing keyboard with alt-shift?

    - by Kosmas Papagiannis
    i just recently installed ubuntu 11.04, english version that comes with libreoffice. I also installed Greek language. Is there some way to make Writer recognize my input language (English - Greek) and apply spelling check on the fly, according to my input language? For example, i type a sentence in English, then switch keyboard input (Alt-Shift) and type a sentence in Greek. Writer does no recognize the Greek sentence and underlines it red. MS Office and OO under Windows does it... As soon as you change input language (keyboard layout), the real time spelling checker changes also between languages... Thank you in advance...

  • How to switch between the upper and lower pane in emacs?

    - by Anthony Kong
    I am using the erlang mode in Aquamacs. The mode, by default, creates a new pane and buffer "*erlang*" when I hit C-C C-K to compile an erlang file. (as seen in the attached screen shot) What is the easiest way to switch between these two panes? I do not think "C-x b" is applicable in this case because 'C-X b' then "*erlang" is slow considering I have to switch between my files and the erlang shell rather frequently.

  • Is there a method to instantly, dynamically switch between several sets of name servers on a single domain with code?

    - by trnsfrmr
    I usually set name servers at an ISP, they often take 24 - 48 hours to resolve. If one has 2 separate sets of name servers (say from 2 domain parking companies) they want to send traffic to, is it possible to switch between the sets instantly without any delays? To be clear, how do you switch mydomain.com (ns1.nameserver1.com, ns2.nameserver1.com) to mydomain.com (ns1.nameserver2.com, ns2.nameserver2.com) instantly?

  • How can I switch my display language to English in Windows 7?

    - by Alon
    Hi, I live in Israel and I bought Windows 7 Professional in Hebrew. I'd like to switch the language to English. In Control Panel - Region and Language I don't have any options to switch the display language to English because only Hebrew is installed. In Windows Update, there are no language updates. I have waited three days, and still no language update. Any Ideas? Thank you.

  • Can I add a gigabit switch to my D-Link WiFi router for gigabit networking? [migrated]

    - by Elmer
    I currently have a D-Link DIR-628 router in my home network that I use for wifi and local networking. However, I am looking to upgrade to a gigabit network as the data transfer speed between my network devices is too slow since the router only supports 10/100. Can I simply add a small gigabit switch (like the Netgear GS105) to the router and connect all local network devices to the gigabit switch ports instead of the router's ports or do I need to replace the entire router to a gigabit router?

  • Any non-custom way to manage iptables with fail2ban and libvirt+kvm?

    - by Peter Hansen
    I have an Ubuntu 9.04 server running libvirt/kvm and fail2ban (for SSH attacks). Both libvirt and fail2ban integrate with iptables in different ways. Libvirt uses (I think) some XML config and during startup (?) configures forwarding to the VM subnet. Fail2ban installs a custom chain (probably at init) and periodically modifies it to ban/unban probable attackers. I also need to install my own rules to forward various ports to servers running in VMs and on other machines, and set up rudimentary security (e.g. drop all INPUT traffic except the few ports I want open), and of course I'd like the ability to add/remove rules safely without restarting. It seems to me iptables is a powerful tool that's sorely lacking some sort of standardized way of juggling all this stuff. Every project, and every sysadmin, seems to do it differently! (And I think there's lots of "cargo cult" admin going on here, with people cloning crude approaches like "use iptables-save like so".) Short of figuring out the gory details of exactly how both of these (and potentially other) tools manipulate the netfilter tables, and developing my own scripts or just manually executing iptables commands, is there any way to safely work with iptables while not breaking the functionality of these other tools? Any nascent standards or projects defined to bring sanity to this area? Even a helpful web page I missed that might cover at least these two packages together?

  • How to (properly) back up a live QEMU/KVM VM?

    - by Roman
    I'm currently engineering a backup solution for KVM VM's as an additional measure to traditional backups. Unfortunately, all currently (August 2013) existing solutions I came across so far either: do not ensure a consistent backup of the VM (losing RAM state, creating a dirty image, or other things), or require lengthy downtime (complete VM shutdown while backing up). I'm aware of QEMU/libvirt's functionality of taking snapshots, however, it's not yet usable since: image-internal snapshots present you with an ever-changing image file, resulting in a likely dirty backup (assuming one uses qcow2 images at all). one cannot yet merge a currently active external snapshot into the original backing image ("blockcommit"). Out of the above reasons, I'm now implementing a script that: Saves the VM's state and halts it Sets up a devicemapper snapshot(s) where the VM's disk images and state reside Resumes the VM Mount the snapshot(s) of step 2. Backs up the VM's disk and state (configuration for convenience) Merges back the snapshot(s). If I got everything right, this will take consistent backups of VM's with only seconds (if at all, since 1-3 is fast, possibly sub-second) of downtime. Of course, when restoring, the VM will be way in the past, but at least giving me the option of an orderly shutdown/reboot. Am I missing something with this solution? Or has someone indeed already implemented this?

    - by Fero
    I am a Software Engineer having 4 Years of experinece in web development using PHP, Drupal, MySql, Ajax and client site technologies like javascript, jquery,html and more. I have decided two platforms to switch over my career. SAP-ABAP (Because ABAP is related to coding) SALES FORCE One and only reason is that I am not getting good pack for the technologies what I am working with. Even top level companies are not ready to pay for this technologies. (And I am not expecting more.) To be honest I am good at technical and HR interviews too. So, I started to make an analysis of highly payable platforms and I got these two. SAP and Salesforce (Probabilty of On-site opportunity is also very high on both) Here my questions are: I am totally new to the above mentioned technologies. Which will be best suit for me ? Having basic ideas of the platforms what I have decided - But I am confused to choose I am having Good Coding experiencein PHP, Drupal as well as good experience in MySql. Having very good experience in creating sites related to E-Commerce, LMS, Q&A sites, Travel Sites, Blogs, Social networking site and more. Which I can learn easily or for which I can get good documentations online Kindly understand that I am not creating a debate over here. I hope Professionals over here can Show me the correct path.... I am waiting to travel on that...

  • Android: how do I switch between game scenes in a game? Any tutorials?

    - by Flavio
    I am trying to create a simple game using the Android SDK without using AndEngine (or any other game engine). I have plenty of experience designing games from the past, but I'm having lots of trouble trying to use the Android SDK to make my game. By far my biggest hurdle right now is switching between views. That is, for example, going from the menu to the first level, etc. I am using a traditional model I learned (I think it's called a scene stack or something?) in which you push the current scene onto a stack and the game's main loop runs the top item of the stack. This model seems non-trivial to implement in the Android SDK, mostly because Android seems to be picky about which thread instantiates which view. My issue is that I want the first level to show up when you press a button on the main menu, but when I instantiate the first level (the level class extends SurfaceView and implements SurfaceHolder.Callback) I get a runtime error complaining that the thread that runs the main menu can't instantiate this class. Something about calling Looper.prepare(). I figured at this point I was probably doing things wrong. I'm not sure how to specifically phrase my issue into a question, so maybe I should leave it as either 1) Does anybody know a good way (or the 'proper' way) to switch between scenes in an Android game? or 2) Are there any tutorials out there which show how to create a game that doesn't take place entirely in one scene? (I have googled for a while to no avail... maybe someone else knows of one?) Thanks!

  • switch statemt functioning improperly and giving error when i put break;

    - by nav
    The following is the code i used in a program - over here the month variable is an integer switch(month) { case 1: case 3: case 5: case 7: case 8: case 10: case 12: return 31; break; case 2: return 28; break; case 4: case 6: case 9: case 11: return 30; break; default: System.out.println("Invalid month."); return 0; } surprisingly, when i use the above switch construct.. it gives an error saying.. code unreachable for statements after each break statement Then i removed all the break statements, and the new code looks like this --- switch(month) { case 1: case 3: case 5: case 7: case 8: case 10: case 12: return 31; case 2: return 28; case 4: case 6: case 9: case 11: return 30; default: System.out.println("Invalid month."); return 0; } Now.. after removing the break statements .. the code worked perfectly well.. My question is... in the switch construct.. it is mandatory to use break.. or else the control flow continued.. and all the conditions are tested and executed!! right??? So why in the world is the previous ** syntactically Right** version giving an error.. and the modified syntactically incorrect version running perfectly well.. Any explanation.. anyone!!

  • How to switch a Sound Ouput Device before the Mac goes to sleep?

    - by Konzepz
    I've connected my MacBook to a set of external speakers with a USB. Now, every time the computer goes to Sleep Mode, there's an awful static sound coming from the speakers. I guess this is some bad wiring; but that's what I've got. However, I can use an idea for a script (AppleScript, bash, whatever) that will switch off the USB output sound in (System Preferences) before the computer goes to sleep, and will switch it back on (if exists) on Wake. Any ideas? Thanks!

  • Switch to another CPanel server, restore mailbox, how to stop Outlook POP3 pull mail data again.

    - by Shiro
    Hi, We switch from a linux CPanel server to another CPanel server, all the setting and file is restore back to the new Linux CPanel server. E.g [email protected] , inside the server I got 100mails. It had been downloaded to my Outlook, my outlook also got 100 mails inside. After I switch to new server, the 100 mail in the old server had been transfer to new server. However, when I open my Outlook, it start to download the 100 mails again, that means I got 200 mails in my mailbox and it is duplicated. How can I stop Outlook to download. The time stamp, receiver and sender is exactly the same. We want to keep a backup in the server, because we don't have a physical server to keep the mail. That why we would like to transfer the mailbox to the new server. Anyone have solution to stop Outlook download again?
