• Ubuntu 13.10 on Acer V5-472 with HD 4000

  - by Hyperboreus

  I have an Acer V5-472 with intel HD4000 graphics chipset and a built-in 1366*768 display. I have installed ubuntu 13.10 amd64 in legacy boot mode with an external monitor. Installation showed no problems, I can boot from HDD and log into my system. The internal display doesn't work and I have to use an external monitor. I have tried the following (found in other threads) to no avail: Setting grub option "acpi_backlight=vendor" or "acpi_osi=Linux" or both. Installing the intel HD drivers for Linux from their homepage. Running in circles, screaming and shouting. The internal display lights up (I can change the brightness with Fn-Left and Fn-Right) but that's all. When I boot, I get a purple splash screen and from then only the external monitor works. I read somewhere that this might be a problem with kernel 3.11? Has anybody ubuntu running on an Acer V5-472? Should I change ubuntu version or use 32-bit instead? In general, how can I get the internal display to work? Edit: The settings-display dialogue shows the internal display correctly with supported resolution of 1366.

• Please recommend a free stealth remote access solution for internal network

  - by Nathaniel_613

  Hi, I need to have ability to stealthfully access, view, and control a few dozen PC's on my company's network. I would need a control panel window, so I can instantly connect to any of the users. Please recommend a secure solution, that will not make us vulnerable to viruses and hackers. All of the PC's have dynamic IP addresses, so I may have to use the DNS name or have a solution that uses web. Thank you very much, Nathaniel.

• Macports irssi & perl5 installation issues

  - by Dmitri DB

  Long time reader, first time poster. Big, appreciative thanks for everyone's collective questioning and answering here and at stackoverflow, it's helped me quite a lot over the time I've been learning answers through these sites! Apologies in advance if I didn't search hard enough on posts already up on this site to find out what I could do about this issue, but I thought I'd just reach out for the sake of trying at least once. I've experienced this issue while starting up my macports-installed version of irssi: 13:25 -!- Irssi: Error in script dispatch: 13:25 Can't locate lib.pm in @INC (@INC contains: /opt/local/lib/perl5/site_perl/5.12.4/darwin-multi-2level /opt/local/lib/perl5/site_perl/5.12.4 /opt/local/lib/perl5/vendor_perl/5.12.4/darwin-multi-2level /opt/local/lib/perl5/vendor_perl/5.12.4 /opt/local/lib/perl5/5.12.4/darwin-multi-2level /opt/local/lib/perl5/5.12.4 /opt/local/lib/perl5/site_perl/5.12.3/darwin-multi-2level /opt/local/lib/perl5/site_perl/5.12.3 /opt/local/lib/perl5/site_perl /opt/local/lib/perl5/vendor_perl .) at (eval 18) line 1. 13:25 BEGIN failed--compilation aborted at (eval 18) line 1. 13:25 Huh, strange.

I'm not really a perl user beyond enjoying it for massive directory-recursive find/replace operations within text files, so I haven't much of an idea what the permissions here are supposed to look like, and I'm not really sure how to go about determining how macports has gone and installed perl this way when it's otherwise worked without failure for years now. Does anyone have any recommendations for the sanest path towards rectifying this issue? Also, is there any interesting reason as to why the macports default for the perl5 port installs 5.12.4, and not 5.16.0, which has to be explicitly installed via the perl5.16 port? Thanks again!

• Is it common to have portable hard drive not recognize?

  - by lamwaiman1988

  I have a bad hard drive which could not be recognized by windows. If windows can recognize it, it could just be pure luck. There are better chance of it being recognize by plugging it at the usb back of the machine, rather than the front one. More interestingly, I have a usb cable which fork itself at one side ( i.e it has 2 heads at one side ). I can plug both heads to the machine and connect the portable hard drive on the other end of the usb cable? Can I get more voltage by doing this? I am guessing the front usb port doesn't have enough power. I am wondering if I buy a new portable usb hard drive, would it have easy read by plugging at the front usb port? I am not sure if I screw up the jumper connecting the front usb ports, but it is okay for other device such as usb stick and mouse.

• Windows 7 / 8 tool for amplifying sound / equivalent to pavucontrol?

  - by Quandary

  I'm watching live streamed videos, but the volume sometimes is barely loud enough. With Windows, I can only turn the system volume and the flash volume up to maximum, and then bad luck if that's still not loud enough. On Linux, on the same notebook, I have the same problem, but I can use pavucontrol to amplify the sound volume beyond 100%. Unfortunately, I can't always work on Linux, since Visual Studio and SQL-Server only run on Windows. Is there any tool or way to amplify volume on Windows 7 / 8 , without having to resort to run Linux in a virtual machine?

• How do you set DEBUG or RELEASE builds in Visual Studio 2008 (VB.net)

  - by GregH

  This has been driving me crazy...I have VS 2008 and am developing vb.net applications. How do I specify if I am building a debug or release version? The description I found of how to do this on the Microsoft site (http://msdn.microsoft.com/en-us/library/wx0123s5.aspx) don't seem to be accurate. This should be pretty straight forward shouldn't it? It seems that a friend of mine that does C# development says it is easy in his environment. Are the VS environments different between C# and VB?

• How to crash a program

  - by user2949019

  I have a program called BlueCoat Proxy installed on my school issued laptop that basically blocks every second website on the Internet, including stack exchange, YouTube and yahoo answers. I do not have administrator rights, nor can I delete anything in program files, I tried every possible method of obtaining admin rights. It is not accessible in task manager (it doesn't even appear there). I tried to close it with Windows command prompt through commands like 'taskkill' but it returns 'Access is Denied' (I'm only denied access with that program). Does anyone know a method of crashing a program with a batch file or VB program? I was thinking something like the ping command, though for a program. Maybe automating 1000 meaningless requests to the program? Your input on the subject matter is appreciated, however telling me that this is wrong or illegal is not.

• Make blink(1) blink a specific color

  - by dimo414

  I'm playing with my new blink(1), and trying to hook it's command line interface into some of my programs, but the docs are a little limited and I'm struggling to figure out how to run even some seemingly simple commands. In particular, the CLI docs say: Usage: blink1-tool <cmd> [options] where <cmd> is one of: .... --blink <numtimes> Blink on/off .... So I try to run blink1-tool --blink 5 and it outputs blink 5 times rgb:0,0,0: and doesn't light up. How do I use the --blink command?

• Music Nav Doesn't Work After Installing IntelliType

  - by Lynda

  I have started using a Microsoft Sidewinder X4 Keyboard. It came with the Microsoft IntelliType Pro software. Since I have installed the software I am not able to change my music via the play | previous | next buttons at the top of the keyboard. I use iTunes and not Windows Media Player. How do I solve this issue? Here is a screenshot of the Keyboard Properties: Note: I am on Windows 8 using iTunes 11. Uninstalling the IntelliType software is not an option as I use the macros.

  I'm trying to create (convert) a Visio architecture diagram from an existing image which is available in the format of JPG extension. My question is, in this complete architecture diagram which I'm trying to convert, there is one specific shape/symbol which I couldn't able to locate/find in the Visio stencil. Can somebody help me in locating this shape/symbol either inside Visio stencil or from any external stencils/symbols? NOTE: I'm using Visio Professional 2013.

• Disabling the soundcard for a specific user

  - by Ron

  Does anyone know how to disable the soundcard when a particular user logs on to Windows XP? My last pair of speakers was blown by an inconsiderate user and I want to disable the sound to the speakers only when a particular user logs on. The PC has multiple users logged on (one of which is me).

• Hyper-Threading and Dual-Core, What's the Difference?

  - by Josh Stodola

  In a conversation with the network administator, I mentioned that my machine was a dual-core. He told me it was not. I brought up the task manager, went to the perfomance tab, and showed him that there are two separate CPU usage graphs. I have a quad-core machine at home and it has four graphs. He told there were two graphs on this particular machine because of hyper-threading. I used to have a hyper-thread pentium 4 processor back in the day, but I never fully understood what it meant. So what is the difference between hyper threading and dual-core? And how do you tell which one you have?

• Cloning single disk drive to multiple drives simultaneously

  - by mr.b

  Hi, I am looking for a way to clone single disk drive to more than one disk drive at the same time. I have prepared system images on 1TB disks, and it takes almost 2 hours to clone one disk to another, and then it goes up exponentially, in order to have say 30 disks cloned. If it was possible to clone one disk to more than single target, it would simplify whole procedure a lot. Also, is there something that prevents this kind of operation? I mean, is there some special reason why every disk cloning software that I know about supports only single target drive? Thanks!

• Does liquid cooling mean I no longer need to dust my machine?

  - by Starkers

  I've got two long haired cats, a dog and I live with a smoker. I use my computer pretty much all day everday, and though I put it to sleep in the night, those fans are constantly going during the day. In just 6 months the rear fans have so much hair wrapped around them it looks more like something from a vacuum cleaner rather than electronic equipment! Due to this, I'm interested in liquid cooling. However, it appears that liquid cooled systems have fans and liquid cooling? Are those just hybrid solutions? They wouldn't really help my situation. There does appear to be fanless systems that use a radiator to dissipate heat. If I implemented one of these could I seal up the vents on my PC and never have to dust it again? Is there a disadvantage to fanless liquid cooling? I don't need to overclock at the moment but I ever want to push my components will fanless liquid cooling be pretty rubbish?

• Windows won't sleep after booting from grub

  - by mkasberg

  I recently added a second hard drive to my computer and I am using it do dual-boot Linux (Ubuntu 12.04) with Windows 7. Both hard drives are SATA. I am using the default grub bootloader on my second hard drive. The windows drive is unmodified. To get to grub, I changed the hard disk boot priority in my BIOS (P35-DS3L) to boot from the second drive. The problem I'm having is that when I boot to Windows 7 (on sda) from grub (on sdb), Windows 7 will not go to sleep (from the start menu). The display shuts off momentarily as if its going to sleep, then comes back on and displays the switch-user screen. Powercfg -lastwake does not show anything. I am sure that this is related to booting from grub on sdb because when I change the hard disk boot priority in the BIOS to boot from my (unmodified) Windows hard disk, the computer goes to sleep fine. It occurred to me that installing grub on sda might solve the problem, but I'd rather not since I like to have my windows hard disk unmodified so that booting to it from the BIOS boots directly to windows. A possible work around is to use the BIOS as a bootloader, by pressing F8 to select the boot device. Still, I'd like to know why the problem is happening in the first place.

• File association for editing on a mac

  - by Agos

  I'm quite experienced with how file association works for opening files on Mac OS X. I recall reading somewhere that OS X keeps not only the information about which apps can open a file, but also which apps can edit a specific file type. I'm having problems with those applications (Coda, Espresso, Forklift, Flow) that have an “edit with external editor” feature, since issuing this command on HTML files opens them with Dashcode. Dashcode of course is not the current association for opening these files (Safari is), so it's clearly looking for apps that can edit HTML. Since I'd like to use TextMate as my editor in these cases, how can I set this preference?

  I was thinking about something. I want to install a 7gb partition and store 2 compress disk image and install linux to it. I want it to be light. What i would like to do is hide the grub loader (or anything) and if i want to reformat my PC press a certain key on startup. Which will then load the linux OS and then i can use dd to restore the partition i want I plan to use windows XP and windows 7 as my main OS and virtualize anything else i need (vista, dummy XP for testing, multiple linux distos, etc). Bonus points if you can tell me how to hide the partition in windows so XP and 7 cant touch it

• Errors reported by "powercfg -energy"

  - by Tim

  Running "powercfg -energy" under Windows 7 command line, I received a report with following three errors: System Availability Requests:Away Mode Request The program has made a request to enable Away Mode. Requesting Process \Device\HarddiskVolume2\Program Files\Windows Media Player\wmpnetwk.exe CPU Utilization:Processor utilization is high The average processor utilization during the trace was high. The system will consume less power when the average processor utilization is very low.

Average Utilization (%) 49.25 Platform Power Management Capabilities:PCI Express Active-State Power Management (ASPM) Disabled PCI Express Active-State Power Management (ASPM) has been disabled due to a known incompatibility with the hardware in this computer. I was wondering for the first error, what does "enable away mode" mean? for the second, what utilization percentage of CPU is reasonable? for the third, what is "PCI Express Active-State Power Management (ASPM)"? How I can correct the three errors? Thanks and regards!

• I can't uninstall Git

  - by Tom

  I was researching Git so I downloaded the Windows version to test it out on a repository on GitHub. After about 30 minutes I couldn't work out how to use it, so I decided I probably wouldn't need a distributed repository as our projects aren't that big and went back to what I know - SVN. (I thought) I uninstalled all the Git related stuff I'd put on my PC, but have now got an irritating problem where if I open any folders I get an error message saying: Hello [ERROR] Could not find git path As you can imagine, this is a real pain, does anyone have any ideas on how to fix it?

• How to skip words in OS X terminal?

  - by Yuval

  Say I wrote a long command in the Mac OSX terminal, i.e say "Hello, how are you? I am good thank you. How is it going with you? Fine, thanks" and now I decided I want to change the word Hello to Hi. To do that, right now I have to keep pressing (or hold down) the left keyboard key until the "cursor" gets to the end of the word Hello, and then delete it. The usual 'holding down option' technique doesn't work as it does in most other OS X applications. Is there a way to skip a word at a time instead (or any other shorter way of getting the cursor there)? Thanks!

• Drag/drop mail folder from Outlook to Explorer export to .pst file?

  - by Alex

  While working on large-scale projects, I collect all mail conversations pertaining to the project in a separate folder within Outlook. When the project is completed, I want to archive the entire folder, for reference purposes. So my question is this: Does anyone know of a tool/plugin for Outlook 2007/2010 that allows you to drag/drop a mailfolder from within Outlook, to a Windows Explorer window, exporting the folder as a .pst file, preserving folder structure and timestamps on mails? I am doing this manually at the moment, but having a tool that would use simple drag/drop-functionality would greatly simplify my workflow for handling project-specific mail.
