  • Upgraded to Ubuntu 12.04--keyboard & mouse no longer work--system down!

    - by Mackey Morgan
    I upgraded from Ubuntu 11 to 12.04, today, and everything seemed to go smoothly up to, and including the reboot. However, I now find that my mouse and keyboard no longer function, so I cannot login or otherwise use my computer. I have read other posts on this topic, but most of the answers seem to require the use of a keyboard to implement the solution--and I can't use my keyboard! I downloaded a 12.04 LiveCD and tried booting from it, but I have the same issue with that--no keyboard! My systems is a Lenovo with an AMD64 dual processor, and my keyboard and mouse are USB attached and shared with two other Windows PCs via a KVM switch (so I no the keyboard and mouse work!). I would appreciate some hints about how to make this PC usable, again. Thanks!

  • RewriteRule for URLs with spaces

    - by Robert Cailliau
    My site's pages are in multiple languages whereby each language version shares its media (images) with the other language versions. I place all versions and the media in a single directory with the same name. E.g. pages mypage-en.html, mypage-fr.html etc. will sit in directory mypage. The directory path suffices to reference a page: h t t p : //....../mypage/ is good enough, there is no need for h t t p : //....../mypage/mypage-en/html A rewrite with RewriteRule ^(.*)/([a-zA-Z0-9]+)/?$ /$1/$2/$2-en.html lets me use the shorter form. But what if the name mypage contains spaces (which some do) ? I want h t t p : //....../my page/ to lead to h t t p : //....../my page/my page.html Using RewriteRule ^(.*)/([a-zA-Z0-9|\s]+)/?$ /$1/$2/$2-en.html did not work. Any hints welcome. (please do not ask me why I want to do this, nor tell me I should not use spaces in file names)

  • New "How do I ..." series

    - by Maria Colgan
    Over the last year or so the Optimizer development team has presented at a number of conferences and we got a lot of questions that start with "How do I ...". Where people were looking for a specific command or set of steps to fix a problem they had encountered. So we thought it would be a good idea to create a series of small posts that deal with these "How do I" question directly. We will use a simple example each time, that shows exactly what commands and procedures should be used to address a given problem. If you have an interesting "How do I .." question you would like to see us answer on the blog please email me and we will do our best to answer them! Watch out for the first post in this series which addresses the problem of "How do I deal with a third party application that has embedded hints that result in a sub-optimal execution plan in my environment?"

  • Compiz plugin (Grid) does not update in CCSM

    - by pileofrocks
    I upgraded to 13.10. Compiz itself has been updated properly to 0.9.10.2, but in CCSM, one* plugin (Grid) shows up as the old version. I know it has been changed and I can actually see the updated version when I log in with another user. This hints of some kind of a problem with per-user settings? (* Actually I'd expect this to involve other if not all other plugins too, but I have simply not yet noticed others.) So far I have tried: resetting Compiz settings to defaults (GUI-way) does not help completely removing & reinstalling compizconfig-settings-manager and compiz-plugins packages does not help In 13.04, I had a patched/old version of the plugin, but I doubt it is about that since everything is fine with the other user (that user account existed already in 13.04). What configuration files I should try deleting?

  • In some games, we just let the main() loop be the Player object or Table object?

    - by ????
    I was thinking that let's say if there is a game of Blackjack or MasterMind, then we should have a class called Dealer or ComputerPal, which is how the computer interact with us (as a dealer for Blackjack or as the person giving hints for MasterMind). And then there should be a Player object, and the way to play one game is aPlayer.playGame but I noticed that a book was just using the main() loop to act as the player (or as the Controller of the game), calling the Dealer methods to dealer the cards, ask for player's action, etc... 1) Is this just a lazy way to model all the proper objects? 2) If more objects are to be added, who should call the aDealer.dealCards and then ask for aPlayer.askForAction? (because it is strange to let the Player handle all the logical steps). Should there be a Table object that handle all these logic and then to play one round of game, use aTable.playGame? What is a good object design for such game?

  • appearance incomplete

    - by user288986
    I'm using 14:04 which is pretty nice. Something wionders me: if I open a window (e.g. Ubuntu Software Centre) I can see SOME items (sometimes nothing) but by hovering the mouse over it it appears - and then disappears again. Sometimes the side mover acts the same way... Maybe it has to do with my hardware: P4, 3 GHz, 2 GB RAM, older graphics board, KVM-switch? There's no difference whether I use Gnome, Ubuntu standard, Ubuntu classic, Ubuntu fallback... Thanks for hints Jens

  • How do I migrate Exchange 2007 to new hardware?

    - by Graeme Donaldson
    As per my previous question, I have an Exchange 2007 box which is also a DC. Since I can't demote it while Exchange is installed, I want to move Exchange to a different server. Does anyone have any articles, tips or experiences to share on this? The last time I did this it was with Exchange 2003 and even that is a little rusty in my head. The setup is a single Exchange 2007 Hub/Edge/Mailbox/CAS server. Its currently on Windows Server 2008, I can migrate it to the same OS, or I can go to 2008 R2, I'm not really picky on that. We're running OWA/ActiveSync/POP3(S)/IMAP(S) for client access. I already have another fully functional DC/GC/DNS box in the same site and clients in the site are already using that for DNS. It's also the preferred site bridgehead for AD replication. Update: After reading Evan's answer I realised that my original question wasn't worded correctly. I'm not looking to do a swing migration, I actually need to move Exchange completely over to a new box. I have done swing migrations in the past, i.e. moving over to a temporary box and back to the original hardware afterwards, and I'm not really sure why I used that term in the original question since it's not what I intended. Any tips?

  • How to set up a server without a hosting control panel

    - by A4J
    I have always used a control panel on my dedicated servers - from cPanel to Plesk to Virtualmin, and I am now considering ditching a CP altogether and manually editing config files. My requirements are fairly simple, I will host multiple sites on the server; some Apache with PHP & Mysql and some Passenger with Rails & Postgres. All will require email smtp/pop. FTP/Stats will not be required. Could someone please give me a quick run-down of what I would need to do - in terms of installing software and configuration? My server will come with a base install of CentOS 6.4 minimal. My thoughts so far: Install/update latest versions of MySQL & Postgres (are they 'safe' out of the box? Or do I need to do anything else like set up root passwords etc?) Install Apache & PHP (again, are the base installs good to go or do they require security tweaks?) Set up nameservers/hostnames/reverse DNS etc (Any guides on how to do this please?) Install Rubygems Install and configure Dovecot and Postfix (any tips on doing this? Or links to how-tos that cover it please?) Set up each website - any links to guides on how to do this? Install/configure firewall (or is the default install good to go?) Any other tips or advice would be greatly appreciated, as would links to guides or how-tos.

  • What steps should I take to secure Tomcat 6.x?

    - by PAS
    I am in the process of setting up an new Tomcat deployment, and want it to be as secure as possible. I have created a 'jakarta' user and have jsvc running Tomcat as a daemon. Any tips on directory permissions and such to limit access to Tomcat's files? I know I will need to remove the default webapps - docs, examples, etc... are there any best practices I should be using here? What about all the config XML files? Any tips there? Is it worth enabling the Security manager so that webapps run in a sandbox? Has anyone had experience setting this up? I have seen examples of people running two instances of Tomcat behind Apache. It seems this can be done using mod_jk or with mod_proxy... any pros/cons of either? Is it worth the trouble? In case it matters, the OS is Debian lenny. I am not using apt-get because lenny only offers tomcat 5.5 and we require 6.x. Thanks!

  • ExtJs textarea multiline issue

    - by PR
    How can I assign text containing \r\n to an ExtJs textarea and get to see line breaks instead of the actual \r\n characters? When I manually press the Enter key and check Firebug, I can see \r\n getting inserted. But if I assign a string containing \r\n to the textarea, it renders as-is. Any hints would be helpful.

Thanks for any hints! Peter

  • How to open call out MKAnnotationView programmatically? (iPhone, MapKit)

    - by StijnSpijker
    I want to open up the callout for an MKPinAnnotationView programmatically. Eg I drop 10 pins on the map, and want to open up the one closest to me. How would I go about doing this? Apple has specified the 'selected' parameter for MKAnnotationView's, but discourages setting it directly (this doesn't work, tried it). For the rest MKAnnotationView only has a setHighlighted (same story), and canShowCallout method.. Any hints if this is possible at all?

  • PowerBuilder Plug-in Architecture

    - by Adam Hawkes
    PowerBuilder seems to have some support for plug-ins since version 10. However, I can't find any documentation nor tutorials about this. The only hints I can manage are by examining the COM objects inside the existing DLLs. It doesn't help much, but I'm a novice at COM development. A very cursory example of how to do something would be awesome.

  • Facebook iframe application redirects to local server

    - by PHP thinker
    I am using FaceBook application inside iframe. But when I try to access it using url like http://apps.facebook.com/myapp, it immediately redirects me to my lhttp://localhost:8080 application, which I intended to keep in frame. I assume that my local application should stay in frame, while the general container would be FB site itself, but something is wrong. Any hints?
