• After turning my monitor off and on, it will display only a white screen

  - by Narf the Mouse

  About a month after installing a new graphics card, I started encountering a rather frustrating problem. Namely, if I turn my monitor off for any significant length of time, then turn it back on, it displays only a white screen. Previously, restarting could fix the problem. However, after leaving the computer off last night, the problem persists. An internet search turned up this site; however, the monitor cable is not loose. As for the insides of the monitor - Well, I could poke around, but I risk making it worse if it's not the monitor. Any such instructions should be clear, detailed and include pictures. Further updates as events warrant.

• Online backup service _with_ filtering (by extension, size and so...)

  - by QyRoN

  Hello, I recentely discovered an ability to backup personal data to online server but I was never surprised when I didn't found a popular service provides filtering capabilities, i.e. all of them they backup all the contents of specific folder. Are there any free options with filtering? To be specific, I need following features: Backup to online server. Automatic but bandwidth-transparent backup, i.e. it will backup my files automatically but won't try to do it if I'm heavily using the computer or internet at the moment. Individual filtering settings for folders, i.e. I want to specify which files to backup in every folder. Some free plan (since I'm not going to use more than 500MB of space).

• Windows 7, how to get unlock (Press Ctrl+Alt+del) prompt on all monitors?

  - by Zugwalt

  I have a laptop that I keep shut in a docking station as I have two screens connected to the laptop and it cannot display to both of those AND its own screen. However, when my computer locks by itself (Not when I lock it using Ctrl+Alt+Del) the login prompt is ONLY on it screen (at least its there when I open it up) and my primary external monitor is off and my other one is all black. This means to log in I have to hit Ctrl+Alt+Del and blindly enter my password--which I don't mind too much, but would prefer if I could actually see the unlock/login prompt instead of typing on a black screen. Any way to have it show the login prompt on all monitors?

• Why do VMs need to be "stack machines" or "register machines" etc.?

  - by Prog

  (This is an extremely newbie-ish question). I've been studying a little about Virtual Machines. Turns out a lot of them are designed very similarly to physical or theoretical computers. I read that the JVM for example, is a 'stack machine'. What that means (and correct me if I'm wrong) is that it stores all of it's 'temporary memory' on a stack, and makes operations on this stack for all of it's opcodes. For example, the source code 2 + 3 will be translated to bytecode similar to: push 2 push 3 add My question is this: JVMs are probably written using C/C++ and such. If so, why doesn't the JVM execute the following C code: 2 + 3..? I mean, why does it need a stack, or in other VMs 'registers' - like in a physical computer? The underlying physical CPU takes care of all of this. Why don't VM writers simply execute the interpreted bytecode with 'usual' instructions in the language the VM is programmed with? Why do VMs need to emulate hardware, when the actual hardware already does this for us? Again, very newbie-ish questions. Thanks for your help

• $DISPLAY dependent gtk themes

  - by Vlad Seghete

  I have a computer at home that I log into remotely. The "monitor" for it is a TV, so I want gtk applications to use a large font and icon theme, which I managed to do by editing the ~/.gtkrc-2.0 file and some other similar stuff. What I want to be able to do is have a separate theme for when I'm logging in remotely. The best way to explain is that I would like my gtk theme choice to be dependent on the X display that the application is started on. For example, if I start something on :0.0 then that is the TV and I want large fonts, but if I start it on localhost:10.0 I want to use a regular size font, because it will get rendered on my laptop screen. The elegant solution would be to have some sort of IF statement in the .gtkrc-2.0 file that checks the $DISPLAY variable and behaves accordingly. The problem is I can't find any documentation on control structures in .gktrc files, or if it's even possible to do that.

• Boot camp install from a HDD image

  - by Dombou

  How would one go about imaging an old work computer (old IBM aptiva from 2001ish) with Windows XP and lots of stuff (VPN client with settings etc) to a new iMac, while preserving Mac OSX? I can't simply install XP on the iMac and then reinstall/copy across stuff; it NEEDS to be an image. Can you even image smaller HDD's and then place them on large ones, or do they have to be the same size? Recommendations on how I go about this? Edit: It MUST be boot camp. I don't want to virtualize it from within OsX

• Extend university wifi network

  - by asfasdoiuh ouhouhouh

  i live in a university campus and i can get wifi signal on the outside of my window but not in the house. The solution i use at the moment is a usb wifi dongle outside connected to my laptop but the lack of an internal antenna make the connection quite unreliable at times. So i was trying to find another solution to improve the reception of my network. One idea is to setup a router on the outside (in a place with stronger signal) and redirect the connection inside the house with an ethernet cable but the problem is that our Uni Wifi is managed by a capitve portal (BlueSocket with DNS redirection to login page) and the authentication has to happen on the mac address that connect to the net (so the client appliance in this case). If I use a router with Mac-Clone capability i will be able to be redirected trough the captive portal on my laptop computer and login from there or i need to setup my router to fill in the login page by itself? There are other hardware/software solutions i can use to get what i want?

• How do I set up two existing disks with identical contents as a single mirrored volume in Windows 7 without losing data?

  - by Software Monkey

  I have two data disks that were, heretofore, in a mobo RAID configuration in Windows 7. They are now separate AHCI disks, visible in Computer Management. How to I go about making them a single mirrored volume in Windows? Note: The data is backed up up on two other separate disks, but it's a fair amount of work to do a restore (over 120'000 files, and I have to reset permissions). Note2: Currently the two disks are identical, and I can use the content of either one for this.

• Leaving job, PC personal info deletion guide?

  - by bangoker

  I'm quitting my current job, and I want to make sure all my personal stuff gets whipped off the computer. I know everybody stores stuff on different places, but is there any quick guide of locations (folders) and apps that might need deletion? you know, just to be sure I erased from all the places and I don't forget any (like those were apps save stuff automatically, the data folders and such) I have erased most of my docs in My Document folder, and I am going to erase all the cookies and stored history in my browsers (opera, ie, ff, chrome) (by the way is there any tool for this?)

• USB HD Freezes Windows Explorer

  - by nfplee

  I recently purchased a "Seagate STBX1000200 1TB Expansion 2.5 inch External Hard Drive". It has been working without problems until recently. When i plug the device into a USB port the device is recognised as it appears in the device manager but when i go to Windows Explorer and try to open it (or right click on it) it hangs/freezes windows explorer. Please note i am using Windows 7 Professional. I have already tried various things without success after searching for people with similar problems. I did read that it could be a problem with how the computer assigns a drive letter. But whrn i go to disk management (when running as an administrator) it hangs and displays the following message: Connecting to virtual disk service I'd appreciate it if anyone could offer some advice. Thanks

• How do I get a PDF link in a Word document to open in the default browser?

  - by Tweek

  I'm trying to create a Word document with links to resources on the web. If I create a hyperlink to a regular HTML file, when I click on the link, it opens in my default browser (Google Chrome) as expected. However, if I click on a link to a PDF file on a website, it opens in Internet Explorer. Before it opens, I also get the following prompt: Microsoft Office Opening http://www.example.com/example.pdf Some files can contain viruses or otherwise be harmful to your computer. It is important to be certain that this file is from a trustworthy source. Would you like to open this file? OK Cancel I'm using Office 2010, but I'm asking for a user who is using Office 2007 and is experiencing the same issue. (His default browser is Firefox.) We're both on Windows 7.

• Ubuntu not showing hard drive

  - by ojek

  I have a laptop which had a broken installation of Windows 7 installed on it. I created a Ubuntu live USB and tried installing Ubuntu over that Windows 7. After a few minutes, I got an error message, so I needed to restart the computer. Now the laptop says that there is no bootable device - reasonable message given that there was an error during Linux installation. However: BIOS can see my hard drive, When I start Ubuntu in live mode, and try either sudo fdisk -l or gparted, it doesn't show any hard disk drives. I am 90% sure that the hard drive is broken, but it is weird that BIOS can see it, and Ubuntu doesn't. How can I be 100% sure about that hard drive? Is there any additional way of detecting my hard drive from Ubuntu?

• Multiple workstation setups using virtualization - best solution

  - by Vazgen

  I'm looking to set up a server for my small startup. I have a few employees and would like to use my computer at home to provide them all with workstations. Each workstation should have the same collection of software installed but each user's workstation should be completely separate from the others. I need each user to be able to remotely log in to their workstation (using TeamViewer or something like it) and I want to be able to monitor their workflow from my screen. I suppose I need a virtualization solution. Can anybody recommend one with easy set up, I'm not a server administrator.

• Somebody knows why the sectors of the IBM floppy disk are named 1 to 8 (and not 0 to 7 )

  - by Olivier Briand

  I am now programming on a 8 bits Z80 computer with CP/M 2.2, (as a hobby) and the floppy disk format is IBM, 40 tracks, 8 sectors per track, 512 bytes per sector. free space is 154 Ko on each face of the disk. Why the sectors are indexed 1 to 8 (and not zero to seven, as usually is seen with computers)? The catalog of the floppy disk is on the track 1 (sector 1 to 4, 64 entries). I'm wondering is the catalog on track zero? Is the zero track reserved to included a system (as track 0 & 1 are reserved to the system on a CP/M floppy disk, and catalog is on track 2)?

• Transferring to a SSD using Windows Explorer?

  - by Nick

  I've just bought a new SSD (regretting this already) which I want to make my primary hard drive on my new computer. It's a fresh Windows 8 install, so I'm wondering if I can just copy the entire contents of C: onto my new SSD drive, or will I need to copy other things too such as boot records? I don't have a CD drive unfortunately (I removed it to put in the SSD - it's a very small HTPC) and I don't have any USB stick to make a bootable copy of Clonezilla or similar. UPDATE: I have decided to re-install Windows 8 from scratch onto the SSD, the problem is obtaining the serial key that is embedded into the BIOS. I actually have a spare, unused product key from my desktop I'm writing on now, but I'd rather not use that when I already have a valid key in my new HTPC :( Thanks :)

• Which interface defines the physical address of a Dialup connection

  - by Debabratta

  I use dial up connection to connect to the Internet. When I type ipconfig/all in the command prompt it shows me a physical address along with description for the dial up connection. The description field shows WAN(PPP/SLIP)Interface. I want to know upon which this physical address depends? It depends on my computer or ISP. On changing my ISP, physical address for this dialup connection will change or remain same? Please give some idea.

• X crashes and GNOME loses all its configuration

  - by Oli

  About every 3 days on my desktop (always on), X crashes, gdm restarts and it dumps me at a login screen. When I log in Gnome appears to have lost a lot of its settings: it plays sounds in weird places, UI elements look like they're from the 90s (GTK+ defaults) and it's generally pretty hideous. Note everything works fine. It's not like my profile doesn't exist because I can browse the internet fine (Firefox knows my bookmarks, history, passwords, etc) and my desktop is unscathed (apart from the icon theme). Manually restarting gdm doesn't fix this. I have to do a full reboot. Now I'm almost certain that this is a nvidia issue causing X to baulk (I've seen similarish threads on nvnews) and I'm happy with that (my fault for running their latest drivers all the time). What I'm concerned about is why Gnome looks so fugly. Is there anything I can do to force it to reload its settings without restarting the whole computer. Restarting is an issue for me as I run several daemons that other computers on the network depend upon. This is what I mean by ugly/fugly... Look at that scroll bar!

• msn 2011 extremely laggy at time?

  - by chobo2

  Hi I am using msn 2011 and think they done a terrible job on it. It seems so buggy. At times when I type a message it is like a slide show. If I would type a sentence you could see it really struggle and the sentence would show up seconds after you typed it. This only happens sometimes. I heard this is something to do with some ad's that are making it slow. Does anyone have a fix for this? Also I noticed like 70% of the time when I check auto login(remember my password and username) it forgets that I checked the box the next time I start my computer up. So I end up typing in my username and password. Thanks

• VMware Workstation 7&8&9 does not generate /etc/vmware/network upon installation

It's strange for me, may be a hardware issue also because with Ubuntu the same thing happens on the same computer.

• Software to create a virtual parallel port in Windows XP?

  - by drknexus

  I am writing a program that will eventually be used on a computer with a physical parallel port and will need to set certain pins high or low in order to signal to an external device. However, the development laptop I am using does not have any physical parallel ports and is too low powered to run a virtual machine. Is there any option available that will create a virtual parallel port within Windows XP? Ideally it would include a debug mode that would allow me to see what values have been pushed out on the parallel port.

• "Device Not Ready" when attempting to connecting an old (DOS) hard drive to windows 7

  - by Christopher Vigliotti

  I have an old Western Digital Caviar 2540 hard drive that I am attempting to connect to a Windows 7 machine by using a Bytecc BT-300 USB 2.0 to IDE/SATA Adapter. I'm connecting things in the right order (power, then sata, then usb) and the jumper settings on the drive are at present set to slave, but am still having an issue. I am recieving a message that the drive is not initialized. When I go into Computer Management I can see the drive (as "Disk 5, Unknown, Not Initialized"), but when I attempt to initialize it or right-click and select "Offline" It tells me that "the device is not ready". Is there something that I can to to get around this, connect the drive and copy the data that I need off of this drive? Is there a third party tool available that I can use?

• Configuring an Engenius 3500

  - by dsiddens

  The title speaks to only half of the issue: the other half are the settings in Ubuntu and the sequences therein. The computer in this issue does receive internet with the external antenna jack at the back being fed with a simple magnetic base antenna designed for putting on the roof of an automobile. However, that signal is weak and the Engenius with an external antenna (Rootenna ~15db gain) and ehternet wire will supply a stronger, faster signal. I've set the Engenius to the desired source and entered the correct WEP password. The lights on the Engenius indicate that it's connected to the access point. At the Ubuntu side of this I've worked to no avail changing settings with "Edit Connections" to the point I'm Ask(ing)Ubuntu for help. I have and have RTFM for Engenius 3500 There is an embarrassing side note to this issue: At one time I had the Engenius working! It seems that I can't recall the settings and sequences I used way back when. And I may as well confess to not knowing the Command Line. I'm a GUI guy. Thank you for your time, Doug

• Cannot connect to internet with Clearwire modem

  - by ide

  I'm currently using a Motorola WiMAX modem (CPEi 25725) and cannot connect to the internet. I can connect to the modem at 192.168.15.1 and check its status. It says that it has good/excellent connectivity to the internet and shows all five signal bars. Additionally it has sent and received some WiMAX packets so I believe it is connected to a tower. I'm at a loss for what the problem is. Unplugging the modem, restarting it from software, and restarting my computer (Windows 7) have not helped. Windows still reports that it is not connected to the internet. Alternatively, could this be an ISP issue? I have heard that Clearwire is a not-so-reputable ISP that blocks VoIP, and I was using Skype recently. EDIT: I called Clear's tech support and apparently their network is having significant problems at the moment. Guess there's nothing an end-user can do about it.
