  • nautilus crash when merging/overwriting files

    - by sBlatt
    On my Ubuntu 10.10, whenever I want to copy some files/folders over some other files/folders, or when I try to empty the trash, nautilus crashes! Example: I have a folder with some files. Now I want to overwrite this folder with a folder with the same name, same files, but some additional files, the merge window comes up, I choose merge and nautilus crashes (does not respond, when I press the close button I can force close it). Some times it even does the copying/emptying (trash), but it always crashes! This happens when copying to the same partition/ntfs partition/netshares, but not when I make a new folder and copy the files/folders into that (without overwriting anything). On a netshare, it's even possible to merge these files afterwards with another computer! dmesg/syslog/messages does not show any entry related to that problem. Does anyone have a solution for this very annoying problem? EDIT: dpkg -l nautilus* (see output in pastebin) EDIT2: I found out, nautilus already crashes before clicking replace/merge (as soon as the question appeares. In the video it's not entirely clear, that i click the cross before the force-close dialog appeares. Video of problem nautilus-debug-log.txt EDIT3: Filed bugreport: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/678233

  • How often is your "Go-To" language the same as your favorite??

    - by K-RAN
    I know that there's already a question asking for your favorite programming language here. I'm curious though, what's your go-to language? The two can be very different. For example, I love Haskell. I learned it this past semester and I fell in love with it's very concise solutions and awesome syntax (I love theoretical math so something like fib = 1 : 1 : [ f | f <- zipWith (+) fibSeq (tail fibSeq)] makes my inner mathematician and computer scientist jump with joy!). However, the majority of my projects for classes and jobs have been in C/C++ & Java. As a result, most of the time when I'm testing something like an algorithm or Data Structure I go straight to C++. What about you guys? What languages do you love and why? What about your go-to language? What language do you use most often to get things done for work or personal projects and why? How often does a language fall into both categories??

  • WCF WebService: Client can't connect, as soon as request client cerficate is activated.

    - by Hinek
    I have an .NET 3.5 WCF WebService hostet in IIS 6 and using a SSL certificate. The communication between client and server works. Then I activate "request client certificate" and the client can't connect anymore Exception: System.ServiceModel.Security.SecurityNegotiationException: Could not establish secure channel for SSL/TLS with authority 'polizei-bv.stadt.hamburg.de'. Inner Exception: System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel. The certificate, the client uses is in the certificate store (local computer), the root ca is int the trusted root certification authorities store. Where can I check for an explanation on the server side? How can I check if the client really supplies it's certificate (client is not on my side)?

  • Is 2 lines of push/pop code for each pre-draw-state too many?

    - by Griffin
    I'm trying to simplify vector graphics management in XNA; currently by incorporating state preservation. 2X lines of push/pop code for X states feels like too many, and it just feels wrong to have 2 lines of code that look identical except for one being push() and the other being pop(). The goal is to eradicate this repetitiveness,and I hoped to do so by creating an interface in which a client can give class/struct refs in which he wants restored after the rendering calls. Also note that many beginner-programmers will be using this, so forcing lambda expressions or other advanced C# features to be used in client code is not a good idea. I attempted to accomplish my goal by using Daniel Earwicker's Ptr class: public class Ptr<T> { Func<T> getter; Action<T> setter; public Ptr(Func<T> g, Action<T> s) { getter = g; setter = s; } public T Deref { get { return getter(); } set { setter(value); } } } an extension method: //doesn't work for structs since this is just syntatic sugar public static Ptr<T> GetPtr <T> (this T obj) { return new Ptr<T>( ()=> obj, v=> obj=v ); } and a Push Function: //returns a Pop Action for later calling public static Action Push <T> (ref T structure) where T: struct { T pushedValue = structure; //copies the struct data Ptr<T> p = structure.GetPtr(); return new Action( ()=> {p.Deref = pushedValue;} ); } However this doesn't work as stated in the code. How might I accomplish my goal? Example of code to be refactored: protected override void RenderLocally (GraphicsDevice device) { if (!(bool)isCompiled) {Compile();} //TODO: make sure state settings don't implicitly delete any buffers/resources RasterizerState oldRasterState = device.RasterizerState; DepthFormat oldFormat = device.PresentationParameters.DepthStencilFormat; DepthStencilState oldBufferState = device.DepthStencilState; { //Rendering code } device.RasterizerState = oldRasterState; device.DepthStencilState = oldBufferState; device.PresentationParameters.DepthStencilFormat = oldFormat; }

  • How to switch off wifi on startup or from the console

    - by mit
    I have installed ubuntu 10.04 on a laptop. Wifi is switched on by default on startup. I can disable it rightclicking the network manager icon in the gnome bar. How can I set it to have wifi switched off as default? Alternatively, how can I switch off wifi on the console? I tried already the rfkill command but it does not list any devices and it does not switch off wifi, I tried different parameters. This is a standard install of the Ubuntu 10.04 i386 Desktop Live CD on an IBM T40 Laptop. EDIT A: This is the output of some rfkill commands on my system, and it does not affect the wifi of the laptop: $ rfkill --help Usage: rfkill [options] command Options: --version show version (0.4) Commands: help event list [IDENTIFIER] block IDENTIFIER unblock IDENTIFIER where IDENTIFIER is the index no. of an rfkill switch or one of: <idx> all wifi wlan bluetooth uwb ultrawideband wimax wwan gps fm $ rfkill list $ rfkill list wifi $ rfkill list all $ rfkill list wlan $ sudo rfkill list all $ sudo rfkill block all $ sudo rfkill block wlan $ sudo rfkill block wifi $ EDIT B: Now I found out that sudo ifconfig eth1 down turns it off. And I can turn it on through the gnome network applet again. But the applet does not reflect the change from the commandline, it stills believes wifi is switched on. I have to switch it off and on again on the applet to switch it on again, when I switched it off from the console. Is there a better way? This is what the syslog looks like when I switch wireless off and on again from the network manager: NetworkManager: <info> (eth1): device state change: 3 -> 2 (reason 0) NetworkManager: <info> (eth1): deactivating device (reason: 0).

  • Building a WSUS server: where to start?

    - by eleven81
    Rather than having all of my computers go out to the internet and download their Automatic Updates, I am seriously considering building a WSUS server. That is, a Windows Update server. I have read some articles, and they have been helpful, but not complete. The following is what I have gleaned are the steps I need to take: Commission a computer to be the server with Windows 2003 Server. Install the WSUS package(s) and select the type of updates to check for. Configure the rest of my computers to be clients of this server. Set the clients to receive updates from the server. My questions are as follows: Does the server have to run Windows 2003 Server, or will Windows XP Professional work? Where do I download the WSUS packages from? How can I configure my computers to look for updates from my server instead of the internet? Thanks!!

  • Scheduled task based on Microsoft patch release cycle

    - by floyd
    I have a simple powershell script which unapproves all patches based on computer group name in WSUS which works great. All of our servers patch on a specific Day/Week/Time starting on Week0-Wednesday which would be the Wednesday after Microsoft Patch Tuesday (2nd Tuesday of every month) all the way to Week3-Sunday. This obviously causes problems as sometimes not all patches get applied in one reboot cycle, and then will install patches the following week during their group policy scheduled patching day/time which is what I'm trying to prevent. My question is I'm trying to schedule my script to run based on this schedule and I am finding it next to impossible using Windows Task Scheduler. For instance if I wanted something to always run on the 4th Monday after Microsoft Patch Tuesday, I cant always use the task scheduler option "4th Monday of the Month" Has anyone run into a similar situation, or know of any task scheduling tools which give you more flexibility than Windows Task Scheduler?

  • Using Mercurial repository inside a Git one: Feasible? Sane?

    - by Portablejim
    I am thinking on creating a Mercurial repository under a Git repository. e.g. ..../git-repository/directory/hg-repo/ The 2 repositories Is it possible to manage (keeping your sanity)? How similiar is it to this? I am a computer science student at University. I manage my work in Git, mainly as a distribution mechanism (after realizing that rsync fails when you have changes in more than one place) between my desktop and usb drive. I try use of Git as a VCS as I do work. I have finished a semester where I did a small group project to prepare for a larger group project next year. We had to use Subversion, and experienced the joys of a centralised VCS (including downtime). I tried to keep the subversion repository separate to my Git repository for the subject**, however it was annoying that it was seperate (not in the place where I store assignments). I therefore moved to using an Subversion repository inside my Git repository. As I think ahead (maybe I am thinking too far ahead) I realise that I will have to try and convince people to use a DVCS and Mercurial will probably be the one that is preferred (Windows and Mac GUI support, closer to Subversion). Having done some research into the whole Git vs Mercurial debate (however not used Mercurial at all) I still prefer Git. Can I have a Mercurial repository inside a Git one without going mad (or it ruining something)? Or is it something that I should not consider at all? (Or is it a bad question that should be deleted?) ** I think outside of Australia it is called a course

  • How can I refresh a document I have open in Excel in read-only mode?

    - by RoboShop
    I have an Excel document that is stored on a SharePoint Server, which I always have open on my computer in read-only mode because I need to refer to it. Every so often, in order to get the latest changes, I have to close down the file and reload it again. Are there any options within Excel 2007 which allow me to simply refresh a document I have open in read-only mode to the latest version on the server? Better still, is there a way where this could be done dynamically, without me having to hit refresh?

  • 12.04 update crash, now cannot boot

    - by EdW
    Boot now freezes the system at the "Ubuntu purple screen" with the 5 dots under it. I cannot even CTRL-ALT-F1 to get to an alternate console. Have to push reset button on computer to reboot. After the 12.04 update crash, the system would boot, but I had no icons and no launch bar and errors about missing dependencies. CTRL-ALT-F1 and ran apt-get -f install and it appeared to get the missing packages. I followed with a apt-get update; apt-get upgrade. It appeared to install all of the remaining 12.04 update packages. Rebooted to same blank screen - no icons, but got a compiz error. In console I tried "unity --reset" rebooted ... Nothing ... It's dead in the water. Tried to boot into Recovery Mode - black screen - I cannot even CTRL-ALT-Del - have to push reboot button. Fortunately, I have Mint on another partition and I can access the broken 12.04 partition. Ideas? I can back up all of my folders using Mint, but I would hate to have to do a new install.

  • Register Game Object Components in Game Subsystems? (Component-based Game Object design)

    - by topright
    I'm creating a component-based game object system. Some tips: GameObject is simply a list of Components. There are GameSubsystems. For example, rendering, physics etc. Each GameSubsystem contains pointers to some of Components. GameSubsystem is a very powerful and flexible abstraction: it represents any slice (or aspect) of the game world. There is a need in a mechanism of registering Components in GameSubsystems (when GameObject is created and composed). There are 4 approaches: 1: Chain of responsibility pattern. Every Component is offered to every GameSubsystem. GameSubsystem makes a decision which Components to register (and how to organize them). For example, GameSubsystemRender can register Renderable Components. pro. Components know nothing about how they are used. Low coupling. A. We can add new GameSubsystem. For example, let's add GameSubsystemTitles that registers all ComponentTitle and guarantees that every title is unique and provides interface to quering objects by title. Of course, ComponentTitle should not be rewrited or inherited in this case. B. We can reorganize existing GameSubsystems. For example, GameSubsystemAudio, GameSubsystemRender, GameSubsystemParticleEmmiter can be merged into GameSubsystemSpatial (to place all audio, emmiter, render Components in the same hierarchy and use parent-relative transforms). con. Every-to-every check. Very innefficient. con. Subsystems know about Components. 2: Each Subsystem searches for Components of specific types. pro. Better performance than in Approach 1. con. Subsystems still know about Components. 3: Component registers itself in GameSubsystem(s). We know at compile-time that there is a GameSubsystemRenderer, so let's ComponentImageRender will call something like GameSubsystemRenderer::register(ComponentRenderBase*). pro. Performance. No unnecessary checks as in Approach 1. con. Components are badly coupled with GameSubsystems. 4: Mediator pattern. GameState (that contains GameSubsystems) can implement registerComponent(Component*). pro. Components and GameSubystems know nothing about each other. con. In C++ it would look like ugly and slow typeid-switch. Questions: Which approach is better and mostly used in component-based design? What Practice says? Any suggestions about implementation of Approach 4? Thank you.

  • Solution for storing sata drives outside of case

    - by Jeffrey Kevin Pry
    I have a system that has 8 sata disks in a software raid 5 array using mdadm. My issue is that I want to move the drives from inside of the computer case in order to cool more efficiently. I have looked all over the web and only seem to find enclosures that hide the drives connectors behind an estata port or some other internal raid controller. Basically what I want is an enclosure or equivalent that I can run independent sata cables to and either power as well, or have it have its own power supply. I have the sata ports on the motherboard available and don't want to limit io by using one port with a multiplier or the like. One final caveat, I am a college student on a budget and don't have a fortune to spend on such an enclosure. Thanks in advance for your help and advice.

  • Exalogic 2.0.1 Tea Break Snippets - Creating and using Distribution Groups

    - by The Old Toxophilist
    By default running your Exalogic in a Virtual provides you with, what to Cloud Users, is a single large resource and they can just create vServers and not care about how they are laid down on the the underlying infrastructure. All the Cloud Users will know is that they can create vServers. For example if we have a Quarter Rack (8 Nodes) and our Cloud User creates 8 vServers those 8 vServers may run on 8 distinct nodes or may all run on the same node. Although in many cases we, as Cloud Users, may not be to worried how the Virtualisation Algorithm decides where to place our vServers there are cases where it is extremely important that vServers run on distinct physical compute nodes. For example if we have a Weblogic Cluster we will want the Servers with in the cluster to run on distinct physical node to cover for the situation where one physical node is lost. To achieve this the Exalogic Virtualised implementation provides Distribution Groups that define and anti-aliasing policy that the underlying Virtualisation Algorithm will take into account when placing vServers. It should be noted that Distribution Groups must be created before you create vServers because a vServer can only be added to a Distribution Group at creation time. Creating A Distribution Group To create a Distribution Groups we will first need to select the Account in which we want the Distribution Group to be created. Once we have selected the account we will see the Interface update and Account specific Actions will be displayed within the Action Panes. From the Action pane (or Right-Click on the Account) select the "Create Distribution Group" action. This will initiate the create wizard as follows. Distribution Group Details Within the first Step of the Wizard we can specify the name of the distribution group and this should be unique. In addition we can provide a detailed description of the group. Distribution Group Configuration The second step of the configuration wizard allows you to specify the number of elements that are required within this group and will specify a maximum of the number of nodes within you Exalogic. At this point it is always better to specify a group with spare capacity allowing for future expansion. As vServers are added to group the available slots decrease. Summary Finally the last step of the wizard display a summary of the information entered.

  • Sync Google Calendar with SharePoint Calendar

    - by dataintegration
    The ADO.NET Providers for Google and SharePoint make it easy to retrieve and update data in both Google's web services and SharePoint. This article shows how the SQL interface to data makes it easy to build applications that need to move data from one source to another. The application described here is a demo Windows application that synchronizes calendar events between Google and SharePoint, but the RSSBus Providers can be used to achieve integrations on both the .NET and the Java platforms, including more sophisticated features like full automation. Getting the Events Step 1: Google accounts can have several calendars. Obtain a list of a user's Google Calendars by issuing a query to the Calendars table. For example: SELECT * FROM Calendars. Step 2: In order to get a list of the events from a given Google Calendar, issue a query to the CalendarEvents table while specifying the CalendarId from the Calendars table. The resulting events can be further filtered by using the StartDateTime or EndDateTime columns. For example: SELECT * FROM CalendarEvents WHERE (CalendarId = '[email protected]') AND (StartDateTime >= '1/1/2012') AND (StartDateTime <= '2/1/2012') Step 3: SharePoint stores data in Lists. There are various types of lists, e.g., document lists and calendar lists. A SharePoint account can have several lists of the same type. To find all the calendar lists in SharePoint, use the ListLists stored procedure and inspect the BaseTemplate column. Step 4: The SharePoint data provider models each SharPoint list as a table. Get the events in a particular calendar by querying the table with the same name as the list. The events may be filtered further by specifying the EventDate or EndDate columns. For example: SELECT * FROM Calendar WHERE (EventDate >= '1/1/2012') AND (EventDate <= '2/1/2012') Synchronizing the Events Synchronizing the events is a simple process. Once the events from Google and SharePoint are available they can be compared and synchronized based on user preference. The sample application does this based on user input, but it is easy to create one that does the synchronization automatically. The INSERT, UPDATE, and DELETE statements available in both data providers makes it easy to create, update, or delete events as needed. Pre-Built Demo Application The executable for the demo application can be downloaded here. Note that this demo is built using BETA builds of the ADO.NET Provider for Google V2 and ADO.NET Provider for SharePoint V2, and will expire in 2013. Source Code You can download the full source of the demo application here. You will need the Google ADO.NET Data Provider V2 and the SharePoint ADO.NET Data Provider V2, which can be obtained here.

  • iwlwifi on lenovo z570 disabled by hardware switch

    - by Kevin Gallagher
    It was working fine with windows 7. The hardware switch is not disabled. I've toggled it back and forth dozens of times. The wifi light never turns on and it always lists as hardware disabled. I have the latest updates installed. I've been searching for solutions, but none of them seem to work for me. I've tried removing acer-wmi. I've tried setting 11n_disable=1. I've tried resetting the bios. I've tried using rfkill to unblock (only removes soft block). I've rebooted dozens of times. The wifi light turns off as soon as grub loads. Edit: I have a usb edimax wireless nic. It shows hardware disabled as well (although rfkill lists as unblocked). If I unload iwlwifi the usb nic works fine. uname -a `Linux xxx-Ideapad-Z570 3.2.0-55-generic #85-Ubuntu SMP Wed Oct 2 12:29:27 UTC 2013 x86_64 x86_64 x86_64 GNU/Linu`x rfkill list 19: phy18: Wireless LAN Soft blocked: no Hard blocked: yes dmesg [43463.022996] Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree: [43463.023002] Copyright(c) 2003-2011 Intel Corporation [43463.023107] iwlwifi 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [43463.023190] iwlwifi 0000:03:00.0: setting latency timer to 64 [43463.023253] iwlwifi 0000:03:00.0: pci_resource_len = 0x00002000 [43463.023257] iwlwifi 0000:03:00.0: pci_resource_base = ffffc900057c8000 [43463.023261] iwlwifi 0000:03:00.0: HW Revision ID = 0x0 [43463.023797] iwlwifi 0000:03:00.0: irq 43 for MSI/MSI-X [43463.024013] iwlwifi 0000:03:00.0: Detected Intel(R) Centrino(R) Wireless-N 1000 BGN, REV=0x6C [43463.024250] iwlwifi 0000:03:00.0: L1 Enabled; Disabling L0S [43463.045496] iwlwifi 0000:03:00.0: device EEPROM VER=0x15d, CALIB=0x6 [43463.045501] iwlwifi 0000:03:00.0: Device SKU: 0X50 [43463.045504] iwlwifi 0000:03:00.0: Valid Tx ant: 0X1, Valid Rx ant: 0X3 [43463.045542] iwlwifi 0000:03:00.0: Tunable channels: 13 802.11bg, 0 802.11a channels [43463.045744] iwlwifi 0000:03:00.0: RF_KILL bit toggled to disable radio.

  • Why enumerator structs are a really bad idea (redux)

    - by Simon Cooper
    My previous blog post went into some detail as to why calling MoveNext on a BCL generic collection enumerator didn't quite do what you thought it would. This post covers the Reset method. To recap, here's the simple wrapper around a linked list enumerator struct from my previous post (minus the readonly on the enumerator variable): sealed class EnumeratorWrapper : IEnumerator<int> { private LinkedList<int>.Enumerator m_Enumerator; public EnumeratorWrapper(LinkedList<int> linkedList) { m_Enumerator = linkedList.GetEnumerator(); } public int Current { get { return m_Enumerator.Current; } } object System.Collections.IEnumerator.Current { get { return Current; } } public bool MoveNext() { return m_Enumerator.MoveNext(); } public void Reset() { ((System.Collections.IEnumerator)m_Enumerator).Reset(); } public void Dispose() { m_Enumerator.Dispose(); } } If you have a look at the Reset method, you'll notice I'm having to cast to IEnumerator to be able to call Reset on m_Enumerator. This is because the implementation of LinkedList<int>.Enumerator.Reset, and indeed of all the other Reset methods on the BCL generic collection enumerators, is an explicit interface implementation. However, IEnumerator is a reference type. LinkedList<int>.Enumerator is a value type. That means, in order to call the reset method at all, the enumerator has to be boxed. And the IL confirms this: .method public hidebysig newslot virtual final instance void Reset() cil managed { .maxstack 8 L_0000: nop L_0001: ldarg.0 L_0002: ldfld valuetype [System]System.Collections.Generic.LinkedList`1/Enumerator<int32> EnumeratorWrapper::m_Enumerator L_0007: box [System]System.Collections.Generic.LinkedList`1/Enumerator<int32> L_000c: callvirt instance void [mscorlib]System.Collections.IEnumerator::Reset() L_0011: nop L_0012: ret } On line 0007, we're doing a box operation, which copies the enumerator to a reference object on the heap, then on line 000c calling Reset on this boxed object. So m_Enumerator in the wrapper class is not modified by the call the Reset. And this is the only way to call the Reset method on this variable (without using reflection). Therefore, the only way that the collection enumerator struct can be used safely is to store them as a boxed IEnumerator<T>, and not use them as value types at all.

  • How to stop mouse "pausing".

    - by Xavierjazz
    My Microsoft mouse recently stopped working, so I purchased an AOpen O-35G, plug and play. No software came with it and I was advised to "just plug it in". I did this, and it worked, although some of the more advanced features do not work. My problem is that now the mouse cursor hesitates occasionally, and then over shoots the target I selected. This never happened before. It seems to happen when I am using the mouse and a browser window reloads. Does anyone know how to change this? It is very annoying. XP Pro SP3 Thanks. EDIT: It is not a problem of dust or a hair. I have contacted the Manufacturere and they are not responding. I have the mouse attached to my computer via a powered USB hub. I am going to try plugging it in directly to see if that makes a difference.

    - by user24559
    I have a remote location that has constant internet access using DSL. The remote location only has three Linksys cameras that use the internet access with a router. There is no computer on the network. The router is configured to use the DYN.org service to keep the IP address updated if the internet provider assigns a new ip address. The problem I am having is the router after a period of time stops responding to incoming ping requests and the cameras are shown offline. However, if I keep one of the cameras constantly streaming data then the connection to all the cameras works just fine all the time. How can I keep the router from appearing to be sleeping and not responding to incoming requests? The router is the Linksys WRT300N.

  • Can't run Ubuntu from disc

    - by alex
    When I place the boot CD in my CD drive and boot from it, I get the Ubuntu menu. I have these options Try Ubuntu without any change to your computer Install Ubuntu Check disc for defects Test memory Boot from first hard disk I can use the cursor keys to select them, and I can push F1 for help etc. However, I can not select an option. I've highlighted the first and tried enter, space bar etc. I do have a KVM, so I plugged in a 2nd USB keyboard and tried it but no go either. I can push escape and then got to the prompt. Am I doing something wrong?

  • Monitor sleep in Windows XP does not work. Is there an add on to force it?

    - by bert
    I have an EEE box with XP Home and a DVI connected TFT, and it does not sleep the monitor. It only starts working after I go to the energy control panel and turn it off and on again. Then the timed sleep works for the current session of computer use. After a shut down and boot next day, sleep does not work again (it is still set in the preferences however). What can hold the sleep function from working? Are there issues with Skype or MSN? Is there a utility to be less critic to processes interrupting sleep and offer a more reliable monitor sleep function for XP?

  • Unix: Sync directory with FTP or SFTP directory

    - by Svish
    I have a website on my local computer running Mac OS X. I am wondering if there is any built-in command that I can run in the Terminal that will upload that website to my webserver either through FTP or, if possible, SFTP. Installing new commands through MacPorts is also a possibility. A big bonus would be that it only uploaded the files that needs to be updated and not everything else. It would also be nice if I can tell it to delete the files on the server that no longer exists locally once in a while. Any good tips?

  • Ubuntu 12.04 does not suspend with proprietary driver for Radeon 6800

    - by Mike
    I'm running Ubuntu 12.04 x86_64 (though these issues have existed in previous releases too) and have a Radeon 6800 graphics card. I've run into issues with the open-source driver (the system would randomly hang when shutting down) so I switched to the proprietary driver (I compiled it myself using these instructions), but I am having new problems now. The main issue is that when I go into sleep mode, about 50-75% of the time, the screen goes black but the monitor does not actually shut off, and I can hear that the fans/hard drive are not suspending either. I can't get the computer to wake up (Ctrl+Alt+F1,2,3,etc. does not work), and I always end up force shutting down with the power button. I'd really appreciate help! Here is some information that might be helpful: $ fglrxinfo display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: AMD Radeon HD 6800 Series OpenGL version string: 4.2.11631 Compatibility Profile Context $ dmesg | grep fglrx [...] [ 6.718606] [fglrx] module loaded - fglrx 8.96.4 [Apr 5 2012] with 1 minors [...]

  • Setting up NIS/NFS on Mac OS 10.6

    - by evan
    We have an Ubuntu NIS/NFS server at work and we recently got a few new iMacs. Is there a way to set them up so they can use the linux user accounts and mount the shared nfs files? Are there any guides on how to do this? I've been googling with no success. I tried getting NFS to work by connecting to the server via the Disk Utility but after I run 'sudo automount' from the command line and ls the directory I tried to mount it to (Volumes/nfs) it gives a permissions error. If there isn't a way to do this, anyone know of any not to complicated ways to share user accounts and files between mac and linux computers (and even hypothetically a windows computer one day?) I know its kind a of huge question, but I'll greatly appreciate any advice on the topic. Thanks!

  • Fixing restore active desktop on windows xp

    - by Rachel Nark
    I've already tried this: http://answers.microsoft.com/en-us/windows/forum/windows_xp-desktop/windows-xp-will-not-restore-my-active-desktop/f664bfe4-0acd-4b11-8918-eb779bb2cc07 had no luck. All I know is that the computer crashed from a power outage. I've tried clicking the restore button and rebooting. Nothing. What else is there to try? Would like to have the desktop back. It powers on fine. I can login and use windows just fine. Just you get that annoying restore active desktop screen.
