• Run a script after killing lxsession (xorg)

  - by user284194

  I am trying to run a program automatically within a bash script after killing the LXDE session. My script consists of: #!/bin/sh pkill lxsession; sh /home/pi/RetroPie/EmulationStation/emulationstation My aim is to log out of the LXDE session and run EmulationStation on my Raspberry Pi with a bash script. I'm using pkill lxsession; to bypass lxsession's logout confirmation dialog. As it stands, this script just gets me to the command line from a working LXDE desktop. Thanks for reading.

• How to install/change locale on Debian?

  - by Hongli Lai

  I've written a web application for which the user interface is in Dutch. I use the system's date and time routines to format date strings in the application. However, the date strings that the system formats are in English but I want them in Dutch, so I need to set the system's locale. How do I do that on Debian? I tried setting LC_ALL=nl_NL but it doesn't seem to have any effect: $ date Sat Aug 15 14:31:31 UTC 2009 $ LC_ALL=nl_NL date Sat Aug 15 14:31:36 UTC 2009 I remember that setting LC_ALL on my Ubuntu desktop system works fine. Do I need to install extra packages to make this work, or am I doing it entirely wrong?

• Computer won't start unless power is removed for ~5 minutes

  - by Paul Tarjan

  I have a fairly standard 2-year old desktop computer (quad-core intel, single hard drive, decent video card, 300W power supply) which recently started acting up. I'm not sure what the cause is, so hopefully you can help. Sometimes (once a week-ish) I press the power button and nothing happens. No blinking, no sounds, no nothing. If I remove the power cord (or flip the switch on the power supply) I hear a capacitor discharge. If I leave it in the "no power at all" state for about 5 minutes then I can put the plug back in and the computer works perfectly. What is the issue? What do you think I have to replace?

• Reinstalling a fresh Windows 8 on my new laptop

  - by AlexV

  OK I have a new Dell (Inspiron 15R 5520) laptop that came with Windows 8 pre-installed. I'm really not a fan of pre-installed Windows since they are bundled with tons of softwares I don't want and settings I don't like. I would like to reinstall it myself with a fresh installation. I have bought Windows 8 Pro OEM already for my desktop computer and it came with the usual OEM sticker with the Windows serial on it. Now my new laptop only have a Windows 8 logo sticker on it with no serial on it. After some research it seems it's normal. Now, can I format my laptop and install Windows 8 (not pro) from my Windows 8 Pro OEM DVD? I ask because when I installed Windows 8 Pro it asked for the serial (which was found on the sticker). I'm wondering if the same DVD will detect the serial on the BIOS of my new laptop or I need a special Dell DVD for that?

• Computer freezes for 2+ seconds, mouse still moves

  - by xsaero00

  I have this problem on my workstation. The computer would effectively freeze for 2-5 seconds for no apparent reason, then continue as normal. While frozen the mouse would still be movable, but only on one of screens in my multi-screen setup. What can be the likely cause. System: CPU: i7-920 Memory: 12G of Patriot DDR3, 6 modules OS: SLED 11, Suse Linux Enterprise Desktop, using Gnome Main board: Asus P6T Video: two Nvidia 9500GT connected to three displays I am using memory at recommended settings of 8-8-8-1333. It has an XMP profile. Th CPU is a bit overclocked to 3.3 GHz, but my cooling more than allows for it. I ran the computer with all overclocks off and lower memory speed but the issue was still there. Any ideas? Where should I start looking?

• Securing RDP access to Windows Server 2008 R2: is Network Level Authentication enough?

  - by jamesfm

  I am a dev with little admin expertise, administering a single dedicated web server remotely. A recent independent security audit of our site recommended that "RDP is not exposed to the Internet and that a robust management solution such as a VPN is considered for remote access. When used, RDP should be configured for Server Authentication to ensure that clients cannot be subjected to man-in-the-middle attacks." Having read around a bit, it seems like Network Level Authentication is a Good Thing so I have enabled the "Allow connections only from Remote Desktop with NLA" option on the server today. Is this acion enough to mitigate the risk of a Man-in-the-Middle attack? Or are there other essential steps I should be taking? If VPN is essential, how do I go about it?

• How do I add a shapefile in ArcGIS via python scripting?

  - by Tom W

  I am trying to automate various tasks in ArcGIS Desktop (using ArcMap generally) with Python, and I keep needing a way to add a shape file to the current map. (And then do stuff to it, but that's another story). The best I can do so far is to add a layer file to the current map, using the following ("addLayer" is a layer file object): def AddLayerFromLayerFile(addLayer): import arcpy mxd = arcpy.mapping.MapDocument("CURRENT") df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] arcpy.mapping.AddLayer(df, addLayer, "AUTO_ARRANGE") arcpy.RefreshActiveView() arcpy.RefreshTOC() del mxd, df, addLayer However, my raw data is always going be shape files, so I need to be able to open them. (Equivantly: convert a shape file to a layer file wiothout opening it, but I'd prefer not to do that).

• Suggestions for wireless adapter

  - by Michael Kniskern

  I recently purchased a desktop computer and it did not come with a wireless network card. I am currently using the Belkin Wireless G USB Adapter and it is a very sub par product. It has very slow response times and download speeds with just basic browsing and downloads podcasts through iTunes. Does anyone have a better suggestion for a wireless adapter? Should I go with another USB adapter or one that connects directly into the motherboard? I am current using Windows Vista 64 bit Home Premium.

• About the External Graphics Card and CPU usage

  - by Balaji

  Hi, We are Rendering 16 live Streams at our client machine through one of our applications and the resolution of the video streams are as 4CIF/MPEG4/25FPS/4000Kbits. The configuration fo the client machine is below. HP Desktop Machine: Microsoft Windows XP Intel (R) Core2 Duo CPU E8400 @ 3.00 GHz 2.99 GHz, 1.94 GB of RAM Intel (R) Q45/Q43 Series Express Chipset (Inbuild) The CPU usage of the machine peaks 99% for 16 straems. After some discussion, we had decided to install external graphics card to reduce the CPU usage. So that, we have tried following graphics cards. NVIDIA Quadro NVS 440 - 128 MB Radeon HD 4350 - 512 MB GDDR2 Redeon HD 4350 - 1GB DDR2 ASUS EAH 4350 Silent 1GB DDR2 But the performance wise no difference, even worst. So, what is the pupuse of these external graphics cards? Really it will reduce the CPU usage? What parameters have to check, if we want to reduce the CPU usage? Please do the needful as soon as possible. Regards Balaji

• Connect to development server via switch?

  - by letseatfood

  I apologize upfront if this isn't appropriate for superuser. I asked it on serverfault and was told it was too general for that site. I have a laptop with Vista and it receives it's internet connection wireless. I have an old desktop with Ubuntu 10.04 Server Edition installed and it is setup as a development server with Apache, MySQL, and PHP. This works well, with the server having a static IP address. The server is connected to the router via an Ethernet cable. Is it possible to disconnect the cable that is currently connecting the server and the router, then connect the server and workstation to a switch, so that I am still able to connect to the server via web browser from the workstation? I am trying to eliminate the long ethernet cable connecting the server to the router in the other room. I already have a switch, that is why I asked specifically about it. Thanks and I will be more than happy to clarify!

• Why is my USB-to-VGA'd monitor working, but not showing in Display Settings?

  - by Strilanc

  I have a USB-to-VGA adapter, which I use to connect a second monitor to my laptop (totaling 3 screens). It worked alright with Vista. I upgraded to Windows 7, and now it no longer works properly (I downloaded the latest drivers just to get it to work on 7). The extra monitor is detected and used to extend the desktop (I can move things onto it, etc), but is not shown within the Control Panel. This is annoying because now I can't changes its resolution, set its logical position to match its physical position, etc. Can I do anything, besides waiting for better drivers? I'm mainly concerned with moving its logical position. (I'd also like to understand how Windows can use a monitor it can't detect. Weird.)

• FTP client that supports 2 concurrent FTP sessions

  - by oninea

  I'm looking for an FTP client that can connect to two different FTP servers at the same time and allow file transfer or synchronization between those two servers. Basically what I want to achieve is to transfer/synchronize files between 2 different sites from my local machine. Are there any clients around that support this functionality? If there are none, is there an alternative to achieve this? I've taken a look at net2ftp, a web based FTP client, which provides almost the same functionality that I need. What I'm looking for though is a desktop app. Any ideas?

• Severe latency only on one machine and only when accessing intranet site

  - by Joe M.

  I have one desktop machine that is having consistently high latency only when trying to load a page from an intranet site. Using the Chrome Developer Tools, the site shows a "Waiting" time of 4-5 seconds each page load. Other machines have <50ms, and the problem machine loads regular internet sites with <1s latency, so the problem is only on one machine and only when accessing the intranet site. This is a small business and all the hosts are on 192.168.0.1/24 I would have suspected a connection issue with the problem machine but normal internet sites are not having latency. Then I would have looked at connection issues with the intranet web server but other machines are not having latency to it. What else can I look at to troubleshoot this?

• How can I find out which driver/file is being loaded when the system hangs during the Windows 7 boot

  - by user24247

  My desktop computer (1 OS, 1 drive, 1 partition) hangs during the Windows 7 boot process. When selecting F8 I can select Safe Boot which allows me to see the files processed during the boot process. I know that the last line displayed is the last file that was SUCCESFULLY loaded. How do I find out what the next line, and the potential candidate driver/file/program would have been? The unusual thing, at least in my experience, is that the freezing up of the system also happens when I boot from the Windows 7 install disks, which is preventing me from any repair options. With a failure of both, I cannot not restore Windows 7 to a previous date or uninstall drivers/programs that may be the cause of the hanging. Thanks for your responses. Marc

• Windows Virtual PC File Copy from host very slow

  - by Shiv Kumar

  I have a Windows 7 desktop on which I've installed Windows Virtual PC and an instance Windows 7. I also have virtual XP instance on the same host. The problem I am having is that copying files from the host to the virtual machine is dog slow. I'm talking 17KB/sec. The host machine has a gigbit NIC. While using the XP virtual instance to do the same I didn't notice a huge difference but on the Window 7 virtual instance the time is really slowing me down. Is there something I need to do (settings) to fix this? I've attached an image of the Resource monitor (of the virtual Windows 7 instance) that shows my network traffic going in bursts rather than relatively steady. The files are on a "public" folder on my host machine.

• How can I dual install Ubuntu 10.4 in a Mac Mini with 10.4.11?

  - by Marco Mariani

  I'd like to power-up my aging Mac Mini (1.5GHz Core Solo, 1GB RAM, Tiger 10.4.11) by installing a shiny Ubuntu alongside the current OS. After all, I use Ubuntu for everything save for cleaning my teeth. Since it's my first and only Mac and I have next to no experience with the OS (having used it basically as a media player) I am a little concerned about rEFIt, ELILO, Boot Camp and the fact that it's basically a 4.5 years old unsupported machine and I might get asleep reinstalling everything several times. I've used the live desktop-i386 CD and everything works. I tried with an external USB drive instead of a CD but couldn't make it boot. As for installing Ubuntu, the howtos I've found give several alternatives depending on the model, the OSX version, etc.. but they usually talk about newer machines. Which howto should I follow to repartition, and boot thereafter? Thanks

• How to Shutdown PC by Pressing Power Button

  - by AgA

  I always Hibernate my PC. Sometimes when I boot, it does not recognize the mouse/keyboard or any USB devices. I've also setup it to go in sleep in 5 minutes. In that case I can't restart the PC so that USB starts working. When I press the Power button then it starts shutdown but asks confirmation twice one is for shutdown by force confirmation and then there is one more. When my USB is disabled I can't input these options. So I switch off the power. What I want is that upon pressing Power Button it should at once start shutdown without asking any more confirmations System details: Win-7 Home Premium 64 bit Intel i3 530 Asus P montherboard EDIT: It is Desktop PC

• Looking for alternative to NetNewsWire and Google Reader

  - by Janine Sisk

  I have used NetNewsWire on both Mac and iPhone for years, and have been reasonably happy. Unfortunately the latest version of NNW for Mac, which I just upgraded to, now matches Google Reader's policy of marking items read after 30 days. The older version I had been using did not do this. I regularly keep unread items for way longer than 30 days, and do eventually read them, so this is a major bummer for me. The iPhone version has behaved this way forever, but I was ok with that as long as I had the full list on my desktop. Keeping in sync between the iPhone and Mac is very important, so I need to find another online solution with clients available on both sides. I've done a little digging but haven't found much; it seems like Google has pretty much taken over this space. Any suggestions?

• Using gnome-do as a dock

  - by Manu

  Hello, I've recently removed the bottom toolbar, in Ubuntu, and replaced it with gnome-do, using the "Docky" theme. Things looks nice, but I have a couple of questions : The dock doesn't differentiate between a shortcut and the application itself when launched. What if I want to launch more than one time that app ? (ie. the console). The dock shows all apps launched, not just the apps launched on that particular desktop. Can I change this behavior ? I haven't found it in the preferences. (image from the blog "OMG Ubuntu", http://d0od.blogspot.com/ )

• How to make outlook.com/Office 365 use plain text and/or conventional quotes?

  - by user23122

  I am forced to use the web version of Outlook at Office 365. I really dislike how it formats e-mail as well as how it handles quoting when replying. In the desktop version of Outlook you can at least force it too display the messages in plain text and then you can manually bottom post/post interleaved. Plain text also changes how it handles quotes: " " is used rather than some braindead RTF version of format=flowed (I like format=flowed when it is implemented without bugs) although the attribution line is completely useless but in the online version I can't find a way to achieve even this. Any ideas? I guess a Greasemonkey script could do this?

• No command window.

  - by Segref

  Using 7 build 7600. Wen I try to open a command window, I just get returned to my previous folder/desktop. If I try to open an extended window I get to the UAC, answer yes and again am returned. A check in Sys info reveals the command prompt is running but I can't see the window. I can have multiple instances of cmd.exe running but still no window. My video adapter is GeForce 7600 and I have no other known problems at this time. Thanks in advance.

• How to route traffic through a specific SOCKS proxy on a per-app basis?

  - by GJ.

  I'm running a certain desktop app (actually via AIR if it makes any difference) which doesn't have any built-in proxy configuration settings. I need to get all traffic just from this app directed through a secure SOCKS proxy. This implies I can't use the global network preferences, as these would affect many other apps. Is there any way to force all network communication through a given SOCKS proxy on a per-app basis? It would also be helpful to know if there's a way to perform such routing globally, based on specific IP addresses (as this could allow for some reasonable workaround).

• Mouse Icon Distorted on Secondary Display

  - by Nathan Taylor

  I have a strange issue with a dual monitor, extended desktop setup where the mouse is always fine on the primary monitor, but sometimes when I move to the secondary display the icon becomes garbled and distorted (sometimes it just looks like a vertical line, instead of a pointer). If I move the mouse back and forth rapidly between primary and secondary displays the level of "garbledness" of the icon will change and sometimes go away completely. If I switch the display settings and set it to "Duplicate Monitor 1" then I end up with a garbled icon on the primary display and an accurate one on the secondary. Very annoying. Computer is Windows 7 Ultimate with an HD8750 and the newest video drivers. Monitors are two Dell 24" displays connected via DVI cables. I have also tried VGA cables.
