  • Can't avoid starting macbook in safe mode

    - by Aaron Brown
    I recently spilled some water on my MacBook (mid-2010) keyboard and it shorted out several of the keys. Notably, control and left option don't work, and the system thinks that the left shift is permanently held down. I plugged in an external USB keyboard and all keys work fine; there's only one problem: The computer always starts in safe mode because the shift key is held down. I've tried holding down other keys (escape, space, c to name a few) and the control key doesn't work so I can't try that. I also tried KeyRemap4Macbook but it doesn't work in safe mode and it doesn't seem to help on startup for me. I can log in to Windows with no problems (with rEFIt) and I can browse the internet with no problems, but I can't program on the Mac OS side in safe mode (it's really slow). Which is mainly what I use this Macbook for. Any ideas out there on how to avoid starting in safe mode?

    Possible Duplicate: Firefox crashes very often - Attempting to load the system libmoon Hi, I am running ubuntu 10.10 and installed firefox 4.0 beta 10 using the ppa:mozillateam/firefox-next, by running the command sudo apt-get install firefox-4.0. However whenever I try running it, it starts up and then within 2 seconds it crashes without any warning. I also don't get the usual warning whether to send the crash report to firefox or not.

  • Optimizing MySQL for small VPS

I'd love to have a kick in the right direction with the MySQL config so I'm not blindly altering it based on the MySQLTuner without understanding what I'm changing. Thanks

  • Quickly open Windows Mobility Center in Windows 8 "tablet" mode

    - by piyo
    I am using a Surface Pro (2013). I would like to know if there is a quick way to open the Windows Mobility Center desktop program. I like to use this program because it is easy to manipulate during the "tablet" (non-keyboard, no-mouse) mode. This program has multiple ways to be started, according to From How to Open and Use Mobility Center in Windows 7 and Windows 8: (Windows 8) Press Windows key + X and select Mobility Center Open the Control Panel and select "Windows Mobility Center" Open the Run dialog and type "mblctr.exe" and press Enter key. None of these are quick and easy when in "tablet" mode. I would ideally like to swipe from right screen edge into to open the Settings pop up and select one icon that opens the Mobility Center. Alternatively, another way I would like to have implemented would be to touch the Windows icon on the tablet screen outside of the viewing area and touch an "app" to launch the Mobility Center. Alternatively, it would be nice to have a Live Tile App that duplicates this functionality.

  • SSH keys fail for one user

    - by Eli
    I just set up a new Debian server. I disabled root SSH and password auth, so you've gotta use a key file. For my primary user, everything works exactly as expected. I used ssh-keygen -t dsa and got myself a public and private key. Put one in authorized keys, put the other in a pem file locally. I wanted to create a user that I can deploy things with, so I did basically the same process. I addusered it, made a .ssh folder, ran ssh-keygen -t dsa (I also tried RSA), put the keys in their appropriate locations. No luck. I'm getting a Permission denied (publickey) error. When I use the exact same keys as the account that works, same error. When I enable password authentication, I can log in via SSH with the password. How do I debug this?

  • Set mouse or keyboard button to simulate left click and hold or rapid left click repeating in Windows?

    - by miahelf
    Does anyone know a way to configure Windows 7 or use third party software to do this? I would like to click my middle mouse button and have it tell Windows to left click and hold until I click the middle mouse button again. A keyboard key would be fine as well. Some games and apps have me holding down the left mouse button for a long time and I would like to reduce the stress on my mouse hand. Also, I would like to do a similar thing but have it repeatedly click the left mouse button automatically if possible. If none of that is possible, how about temporalily setting a keyboard key to achieve a left mouse button emulation?

  • Remapping Home/End from PC to Mac Via Synergy is not client specific.

    - by DtBeloBrown
    This question asks about the end key but the answers give no examples: http://superuser.com/questions/60052/what-key-works-like-end-using-a-mac-with-synergy If they had, I am guessing that they would likely have run into this problem. Adding lines like the bottom two of this: section: options keystroke(End) = keystroke(Control+Right,myiMac) keystroke(Home) = keystroke(Control+Left,myiMac) to my synergy.sgc in MyDocuments on the winXP machine would work but causes the keys to stop functioning on the winXP machine. Unacceptable. I next tried a compromise: keystroke(End) = keystroke(Control+Right,myiMac); keystroke(End,myPc) keystroke(Home) = keystroke(Control+Left,myiMac); keystroke(Home,myPc) Expecting that to broadcast the keystrokes to both machines regardless of which one was the Active Screen. That and many other variations did not work. What am I doing wrong? Has someone actually done this?

  • How can I have Windows 8 go to the desktop by default?

    - by Schnapple
    I've played around a smidge with the Windows 8 Consumer Preview in a VirtualBox VM and I think the improvements under the hood may be worth tolerating the Metro UI crap. I don't like that the entire screen changes to something I don't care about when I hit the Windows key and start typing but I can deal with it. The one thing I cannot stand, though, is that it starts in the Metro interface by default. I have to hit the "Desktop" tile to get to a normal interface, and while I can hit "escape" to go back to the desktop and dismiss Metro, it doesn't work when you first log in. When you first log in, you have to hit that "Desktop" tile. I know that the Enterprise versions of Windows 8 will go to the desktop by default. I don't know but I would assume that there's probably some registry key that would handle this. Has anyone figured that out yet?

  • Create bootable USB install image from command line?

    - by j-g-faustus
    I'm trying to create a bootable USB image to install Ubuntu on a new computer. I have done this before following the "create USB drive" instructions for Ubuntu desktop, but I don't have an Ubuntu desktop available. How can I do the same using only the command line? Things I've tried: Create bootable USB on Mac OS X following the ubuntu.com "create USB drive" instructions for Mac: Doesn't boot. usb-creator: According to apt-cache search usb-creator and Wikipedia usb-creator only exists as a graphical tool. "Create manually" instructions at help.ubuntu.com: None of the files and directories described (e.g. casper, filesystem.manifest, menu.lst) exist in the ISO image, and I don't know what has replaced them. (At my disposal is Mac OS X and Ubuntu server; I have neither Ubuntu desktop nor Windows.)

  • What commands are needed to install Ubuntu Core?

    - by Oxwivi
    Ubuntu Core's wiki page page contains the instructions to install Ubuntu Core on a target media: Uncompress (do not unpack) rootfs Format target media: at least one partition should be ext2, ext3, or ext4 Unpack Ubuntu Core to ext{2,3,4} partition Install boot-loader Install Linux If the Linux kernel requires modules, add these to /lib/modules/$(uname -r) in the ext{2,3,4} file system Boot the target device Install any additional required software using apt-get But what are the specific commands to do the above? The things I'm specifically confused about are: Uncompressing and unpacking, what's the difference and how do I do them? What package should I install if I want the generic kernel provided in regular Ubuntu installation? I won't be installing any drivers or anything related to kernel other than what's provided in the repos, do I need to worry about manually adding kernel modules? PS I would like to request that all the commands used in the installation process be mentioned in the answer, for the benefit of ones who're completely unfamiliar and myself, should I ever forget.

  • Keyboard / keymap problems with Xubuntu 12.04 + NX nomachine

    - by bajafresh4life
    I'm running NX client on my Macbook Pro to connect to a Xubuntu 12.04 desktop at work. I have configured NX client to start up a console upon connection. I am able to connect to my remote linux machine and I get a simple xterm console. However, when I run xfce4-session, half my keys no longer work. For example, when I launch a terminal, I typing a, s, or d works, but if type w, e, r, or t, the cursor just blinks. If I ctrl-C out of xfce4-session, all the keys work fine in my xterm console. If I run xev, this is the output for when I hit a key that works: KeyRelease event, serial 34, synthetic NO, window 0x2e00001, root 0x373, subw 0x0, time 170160781, (-45,-21), root:(824,429), state 0x4, keycode 16 (keysym 0x63, c), same_screen YES, XLookupString gives 1 bytes: (03) "" XFilterEvent returns: False KeyRelease event, serial 34, synthetic NO, window 0x2e00001, root 0x373, subw 0x0, time 170160781, (-45,-21), root:(824,429), state 0x4, keycode 67 (keysym 0xffe3, Control_L), same_screen YES, XKeysymToKeycode returns keycode: 63 XLookupString gives 0 bytes: XFilterEvent returns: False but when I hit a key that doesn't work: FocusOut event, serial 34, synthetic NO, window 0x2e00001, mode NotifyGrab, detail NotifyAncestor FocusIn event, serial 34, synthetic NO, window 0x2e00001, mode NotifyUngrab, detail NotifyAncestor KeymapNotify event, serial 34, synthetic NO, window 0x0, keys: 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Any ideas on what I can do to troubleshoot this issue? Googling around offered a few suggestions (like playing with xmodmap) but nothing seemed to work. Also, one thing worth mentioning is that I do not have any keyboard issues when remoting into a different Ubuntu 10 box via NX.

  • Plymouth did not install properly

    - by David Starkey
    I was installing the plymouth manager in hopes of making a custom loading screen. While the terminal was working, my computer unexpectedly powered off. I can open up the manager and it appears to do what it is supposed to (minus the fact that I can't make my own theme) and the screen only shows on powering down. Anyway, all of the advice I have seen so far have resulted in errors and nothing getting fixed. I do not have permissions to simply select the folder and delete it for some reason and I have not been able to find out how to grant myself those permissions. I guess my question then is how do I get rid of the plymouth manager so I can reinstall it properly?

  • Enabled storing Bitlocker keys in Active Directory, is there a way to upload keys of drives encrypted before this?

    - by Rossaluss
    We have enabled storing of Bitlocker keys within the device object on Active Directory, however before this was implemented, we had encrypted 100+ devices using bitlocker and we've only found ways to upload the key to AD when enabling bitlocker for the first time on an install. Does anybody know of a way where we can upload all the keys for all the devices which already had their drives encrypted with Bitlocker into their respective device objects in AD? Or are we going to have to decrypt and re-encrypt all the devices on the floor? (Google seems to say this is what we're going to have to do, however we're no experts in Bitlocker, so may have missed something) When we go into Manage Bitlocker of an already encrypted device, we only get the same options of saving the key to a file, a memory stick or printing it out, no option is available to save to AD etc. Any help would be appreciated.

  • Shibboleth: found encrypted assertions, but no CredentialResolver was available

    - by HorusKol
    I've gotten a Shibboleth Server Provider (SP) up and running, and I'm using the TestShib Identity Provider (IdP) for testing. The configuration appears to be all correct, and when I requested my secured directory I was sent to the IdP where I logged in and then was sent back to https://example.org/Shibboleth.sso/SAML2/POST where I am getting a generic error message. Checking the logs, I am told: found encrypted assertions, but no CredentialResolver was available I have rechecked the configuration, and there I have: <CredentialResolver type="File" key="/etc/shibboleth/sp-key.pem" certificate="/etc/shibboleth/sp-cert.pem"/> Both of these files are present at those locations. I've restarted apache and retried, but still get the same error. I don't know if it makes a difference - but only a subdirectory of the site has been secured - the documentroot is publicly available.

  • 'Content' is NOT 'Text' in XAML

    - by psheriff
    One of the key concepts in XAML is that the Content property of a XAML control like a Button or ComboBoxItem does not have to contain just textual data. In fact, Content can be almost any other XAML that you want. To illustrate here is a simple example of how to spruce up your Button controls in Silverlight. Here is some very simple XAML that consists of two Button controls within a StackPanel on a Silverlight User Control. <StackPanel>  <Button Name="btnHome"          HorizontalAlignment="Left"          Content="Home" />  <Button Name="btnLog"          HorizontalAlignment="Left"          Content="Logs" /></StackPanel> The XAML listed above will produce a Silverlight control within a Browser that looks like Figure 1.   Figure 1: Normal button controls are quite boring. With just a little bit of refactoring to move the button attributes into Styles, we can make the buttons look a little better. I am a big believer in Styles, so I typically create a Resources section within my user control where I can factor out the common attribute settings for a particular set of controls. Here is a Resources section that I added to my Silverlight user control. <UserControl.Resources>  <Style TargetType="Button"         x:Key="NormalButton">    <Setter Property="HorizontalAlignment"            Value="Left" />    <Setter Property="MinWidth"            Value="50" />    <Setter Property="Margin"            Value="10" />  </Style></UserControl.Resources> Now back in the XAML within the Grid control I update the Button controls to use the Style attribute and have each button use the Static Resource called NormalButton. <StackPanel>  <Button Name="btnHome"          Style="{StaticResource NormalButton}"          Content="Home" />  <Button Name="btnLog"          Style="{StaticResource NormalButton}"          Content="Logs" /></StackPanel> With the additional attributes set in the Resources section on the Button, the above XAML will now display the two buttons as shown in Figure 2. Figure 2: Use Resources to Make Buttons More Consistent Now let’s re-design these buttons even more. Instead of using words for each button, let’s replace the Content property to use a picture. As they say… a picture is worth a thousand words, so let’s take advantage of that. Modify each of the Button controls and eliminate the Content attribute and instead, insert an <Image> control with the <Button> and the </Button> tags. Add a ToolTip to still display the words you had before in the Content and you will now have better looking buttons, as shown in Figure 3.   Figure 3: Using pictures instead of words can be an effective method of communication The XAML to produce Figure 3 is shown in the following listing: <StackPanel>  <Button Name="btnHome"          ToolTipService.ToolTip="Home"          Style="{StaticResource NormalButton}">    <Image Style="{StaticResource NormalImage}"            Source="Images/Home.jpg" />  </Button>  <Button Name="btnLog"          ToolTipService.ToolTip="Logs"          Style="{StaticResource NormalButton}">    <Image Style="{StaticResource NormalImage}"            Source="Images/Log.jpg" />  </Button></StackPanel> You will also need to add the following XAML to the User Control’s Resources section. <Style TargetType="Image"        x:Key="NormalImage">  <Setter Property="Width"          Value="50" /></Style> Add Multiple Controls to Content Now, since the Content can be whatever we want, you could also modify the Content of each button to be a StackPanel control. Then you can have an image and text within the button. <StackPanel>  <Button Name="btnHome"          ToolTipService.ToolTip="Home"          Style="{StaticResource NormalButton}">    <StackPanel>      <Image Style="{StaticResource NormalImage}"              Source="Images/Home.jpg" />      <TextBlock Text="Home"                  Style="{StaticResource NormalTextBlock}" />    </StackPanel>  </Button>  <Button Name="btnLog"          ToolTipService.ToolTip="Logs"          Style="{StaticResource NormalButton}">    <StackPanel>      <Image Style="{StaticResource NormalImage}"              Source="Images/Log.jpg" />      <TextBlock Text="Logs"                  Style="{StaticResource NormalTextBlock}" />    </StackPanel>  </Button></StackPanel> You will need to add one more resource for the TextBlock control too. <Style TargetType="TextBlock"        x:Key="NormalTextBlock">  <Setter Property="HorizontalAlignment"          Value="Center" /></Style> All of the above will now produce the following:   Figure 4: Add multiple controls to the content to make your buttons even more interesting. Summary While this is a simple example, you can see how XAML Content has great flexibility. You could add a MediaElement control as the content of a Button and play a video within the Button. Not that you would necessarily do this, but it does work. What is nice about adding different content within the Button control is you still get the Click event and other attributes of a button, but it does necessarily look like a normal button.

  • Cannot activate windows 7

    - by Charlie
    I can't activate Windows 7, I get an error saying DNS name does not exist. Is something configured incorrectly somewhere? PS: I need the answer within 13 days ;) UPDATE: I had upgraded from my company's Windows Vista build, and when I connect to the company VPN and activate I get a different error: The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information. The Application Event Log contains this (I took out the server name, it's one of the company servers): The client has sent an activation request to the key management service machine.

  • Installing MonoDevelop 2.10

    - by missingfaktor
    sudo apt-get install monodevelop installs MonoDevelop 2.8.x. The official site, http://monodevelop.com/Download, states that "Packages for MonoDevelop 3.0.3.5 not yet available. The latest available version is MonoDevelop 2.6.0.1". I want to use the F# plugin for MonoDevelop which supposedly is only available for MonoDevelop 2.10.x and latter releases. How do I install MonoDevelop 2.10.x or latter on my Ubuntu? Or is it not possible at all?
