• Windows XP dual screen problems, user account related

  - by Chris

  I have had this issue with a few laptops now and it looks like it is some sort of user account problem. Specifics of the system are: Dell Laptop Windows XP Pro SP3 Non-domain member computer DLP Projector connected to laptop via VGA I use this setup almost daily to do presentations, always the mirrored display mode where I can see on the laptop monitor the same thing that is displayed on the projector. Today, when I boot up, I get the mirrored display at the login screen, but after I log in, it switches to Extended Desktop (like two desktops side-by-side). Fn+F8 just cycles through all the normal settings except the mirrored display. I created a new user account on the computer and it performs normally. Mirrored display works as normal. I have run into this about 4 times now and it always can be solved by creating a new user account on the computer, and then all is well. I would like to either: 1. Find a way to reset the customized settings for a specific user account which would hopefully make this go away, or 2. Find the specific setting that causes this so that I can easily fix it when the problem comes up. Creating new user accounts is kind of a pain and a easy fix must be out there somewhere.

• Windows 7 Blank Screen on Boot / Login

  - by Greg

  I have a new system that's having a few problems... sometimes (seems to be when the PC is cold, i.e. has been switched off for a while, though that could be my imagination) I get a blank blue screen when I boot up. The system boots normally and auto-logs-in. The desktop loads and I'm even able to launch applications, but then everything disappears and the screen goes to the default windows desktop blue colour (not the desktop image, just a plain blue with no mouse cursor). At this point the machine completely locks up - I'm unable to even toggle Num Lock and have to hold in the power button for 5 seconds to kill it. Interestingly if I manage to launch some applications before it goes blank, they will usually crash... sometimes explorer.exe will crash too. When I reboot, the system is fine and stable. I've installed the latest graphics drivers and run memtest86+ for 6 passes (and counting) with no errors. The system specs are: CPU: Intel I7 2.66 @ 3.4GHz RAM: 6GB (3 * 2GB DDR3) HDD: 128GB Crucial M225 SSD Motherboard: Gigabyte EX58-UD3R Gfx: ATI Radeon Sapphire 5870 1GB Note: There are a few similar questions but I haven't found one that matches my symptoms

• Windows 7 home backup solution, with offsite provision

  - by Richard E

  I am looking for a home backup solution for my single Windows 7 (Home Premium) PC. I have about 500GB of data to backup. I would like to spend less than GBP 300 on the solution. I don't see the need to backup the whole PC, rather specific folder branches (iTunes, photos, documents, Outlook files, user folders such as desktop, favorites etc). I would like a solution that enables me to maintain backups in two separate physical locations (e.g. home and work). To facilitate this I am imagining a storage unit with slots for two removable drives, along with three separate drives. At any one time two of the drives will be being backed up to in the storage unit. The third will be located at my work. Periodically I will take one of the drives into work and leave it there, then bring the drive that was there back home, and plug it into the storage unit. It will then be backed up along with the other drive that was left in the storage unit. This approach should cover scenarios such as virus attack and fire or theft from one location. Thoughts and comments on the sanity of this approach please...

• Getting 2560x1600 out of an ATI Radeon HD 4670 on Windows 7

  - by Alexey

  Greetings, I've got a Dell Studio XPS 1640 laptop (with an ATI Radeon HD 4670 graphics card) running Windows 7, and just bought a Dell 3007HPC 30-inch monitor for it. I'm trying to figure out how to get the full 2560x1600 experience out of this setup. Here's what I've done so far: Plug in using an HDMI cable and an HDMI--D-DVI converter on the monitor side. Open up Screen Resolution. Maximum supported setting is 1920x1080. Tried that (several times) - sometimes it doesn't work at all (blank screen); other times, it only shows the first 1280x800 pixels on the bigger screen. Tried using the Catalyst control center - played with various settings there, couldn't get the screen to show anything interesting. Tried using PowerStrip to set a custom resolution, again, no luck. Spoke to a Dell Preferred Custom Support guy for about an hour before giving up. He remote-accessed my computer, and told me that (1) The maximum supported resolution for XPS 1640 is 1920x1080, and (2) 'it seems to be working from where he sees it, must be a connection issue'. None of this has helped. Does anybody have ideas? Should I be using a different cable set up? Am I using Powerstrip wrong?

• Why don't we use dynamic (server-side generated) CSS?

  - by ern0

  As server-side generated HTML is trivial (and it was the only way to make dynamic webpages before AJAX), server-side generated CSS is not. Actually, I've never seen it. There are CSS compilers, but they generate CSS files which can be used as static. Technically, it requires no special libraries, the HTML style tag should reference to the PHP(/ASP/whatever) templater script instead of the static CSS file, and the script should send out CSS content-type header - that's all. Does it have cache problems? I don't think so. The script should send out no-cache etc. headers. Is it problem for designers? No, they should edit the CSS template (as they edit the HTML template). Why we don't use dynamic CSS generators? Or if there's any, please let me know.

• Problems with word completion on Windows Mobile

  - by Rowland Shaw

  For "some reason" the word completion function on my windows mobile phone (HTC Diamond, rebadged as a T-Mobile MDA Compact IV (UK) running WM6.1 with HTC Touch Flo 3D) hasn't worked since one of my firends was taking a look at the phone (I remember him bitching about it being too obtrusive for him, as an iPhone fanboy). I've checked all the obvious settings ( Start Input Word Completion ) and everything looks set there; I tried a hard reset, to no avail and even tried upgrading the ROM t the latest from my network provider. I even tried walking into the store where I bought the phone, and the staff couldn't fix the issue. I still have my old handset, which also runs WM6.1 (a T-Mobile MDA Compact III (UK), albeit without Touch Flo 3D), and the word completion works on there, so I'm a little confused as to why I can't get it to work again on my new handset. Can anybody identify why this might not be working, or help me fix it? Edit: Even "Touch Input Settings" has both "Word Completion in T9 mode" and "Word Completion in ABC mode" checked. The full qwerty keyboard option is in T9 mode, and word completion works for this input method; It still does not work for my preferred, "Letter Recogniser" method.

• how to reinstall ubuntu 12.04 after dual boot installation fails with windows 7

  - by Rini

  I have installed Ubuntu 12.04 on my preinstalled windows 7 Sony vaio s series laptop following instructions here: http://www.linuxbsdos.com/2012/05/17/how-to-dual-boot-ubuntu-12-04-and-windows-7/ Everything went well and I am able to boot in to windows after complete installation of Ubuntu. Now following instructions on web I tried to add Ubuntu to my BIOS using Easy BCD (but forget to add windows 7 entry). As a result, I loose windows 7 OS and can't boot in to either OS then I successfully repaired windows 7 using recovery CD. Now my problem is that I can't reinstall Ubuntu 12.04 using Live CD it halts every time before disk partition step giving error. There is only one partition which corresponds to windows 7 but I don't know whether the Ubuntu is still there or probably corrupted. So, how to repair it or again install ubuntu ? Please suggest what I should do now? Thanks in advance. R Shukla

• No LPT port in Windows 7 virtual machines

  - by KeyboardMonkey

  Windows 7 has MS virtual PC integrated, the VM settings don't give a parallel LPT port mapping to the physical machine. Where did it go? Has anyone else noticed this, and found a solution? Update: After much digging, I found the one and only reference to this issue, on the VPC Blog: "Parallel port devices are not supported, as they are relatively rare today." -More details- It's a XP VM I've been using since VPC 2007 days, which did have this functionality. This is to configure barcode printers via the LPT port. Since the (new) MS VM can't map to my physical LPT port, I'm having a hard time configuring printers. My physical ports are enabled in the BIOS. It has worked the past 3 years, before switching to Win 7. Any help is appreciated. This screen shot of the VM settings shows COM ports, but LPT is no more In contrast, here is a screen shot of VPC 2007 (before it got integrated into Win 7). Notice how it has LPT support

• Windows Phone 7 Development &ndash; Useful Links

  - by David Turner

  Here are some excellent links for anyone developing for Windows Phone 7: J.D. Meier’s Windows Phone Developer Guidance Map – this is immense.  Also check out the Silverlight version Justin Angel’s site – some really great articles on unlocked roms, automation and Continuous Integration Windows Phone 7 Development Best Practices Wiki Jeff Blankenburg’s 31 days of Windows Phone 7 This post of Links to sample code for Windows Phone Tim Heuers blog, particularly this post of Tips and Tricks Kevin Marshall's blog, particularly the epic WP7 Development Tips Part 1 post Code Samples for Windows Phone on MSDN If you have unlocked your phone for development, then you can use the WPConnect tool to connect to the device rather than using the Zune client.  I found it useful to pin a shortcut to WPConnect in my Start Menu. The Performance Counters displayed when you debug your app on a device are useful for seeing things like frame rate and memory usage, this page on MSDN explains what the numbers mean.  Jeff Blankenburg covers this in more details on his blog I also came across this set of links to tutorials recently which looks very useful.

• Software Diagnostics Tool recommendations for Debugging a Windows 8 freeze

  - by Stuart

  I've had my HP Pavillion dv6 laptop since last November - and it has had 8GB RAM and a 256GB Crucial M4 SSD installed since the start. I use it for software development and it's had a Windows 8 RTM installation since early September. Yesterday I had to give a presentation at a customer site - so used Powerpoint for the first time since installing Win8... since that point my machine has 'frozen' every 2 hours or so after startup. There doesn't seem to be any easy to see reason behind the freeze - the system just freezes, even if I have left it idle with just a desktop there. My immediate suspicion is that the SSD is the mostly likely cause of the problem. I've looked at some of the questions on here - e.g. How do I troubleshoot hardware issues related to a computer freeze/crash? - but don't really want to start taking my laptop apart. Another suspicion is that this might be related to the WiFi adapter (Broadcom 802.11n) since I have noticed that this doesn't seem to play perfectly with things like Hyper-V in Win8. Can anyone recommend any software diagnostic tools that I can run in order to evaluate the health of the SSD or of other parts of the system? Thanks Stuart P.S. I doubt Powerpoint is the cause of this, but I may use it as an excuse never to use it again... More realistically perhaps something got damaged during travel to the customer site?

• Windows Vista - Can Boot into Safe Mode Command Prompt, Cannot Access Flash Drive

  - by Adam

  Hey there, Got a laptop dropped into my lap. Has Vista installed. Normal boot never gets past the login screen. Safe mode will get past, but just barely. I can try and start the task manager at that point, but it never opens. Only reliable way to do anything I've got is the safe mode command prompt... Boots up and logs in fine. I can't see anything noticably wrong via regedit, but it's been a long time since I've had to fix up a Windows box... not sure that I would. Problem I'm having, is that I want to run ComboFix/etc, but have no way to get them on there... When I pop a flash drive in, it seems to mount it (flash drive flickers as normal) but it never seems to be mounted... I cannot access it through any drive letter on the command line. I managed to start the device manager (devmgmt.msc) and the flash drive was recognized and listed... Any ideas on how to get this thing going again? (Short of a reinstall.) (It has no CD drive, either, so burning files to CD would not be easy...) Thanks! Adam

• Silent install FirePro v4900 Driver on Windows Embedded 7 Standard

  - by Birgit_B

  I'm trying to install the Drivers for a FirePro v4900 on a Windows Embedded 7 Standard 64bit OS. I want the system to be as small as possible, so i would rather not install the whole catalyst control center, but only the necessary drivers. Because the installation should be accomplished absolutely unattended, the installation process of the FirePro-Driver should also be done without any user interaction. I see two possible solutions for the Problem: Install only the Drivers: Is it possible to solely install the necessary drivers? How would i achieve that? This solution would be the preferred one, because of the smaller footprint. Silent custom install the provided "FirePro_8.911.3.3_VistaWin7_X32X64_135673.exe" (found at ATI FirePro™ Driver). Is there a way, to do that? Thank you in advance for your support! Update: I managed to accomplish a silent installation. I extracted the contents of the above mention installer-file and ran \$_OUTDIR\Bin64\Setup.exe -Install. (There are some other Parameters, just run Setup.exe /?). But i couldn't achieve to just install the drivers without the Cataclyst Control Center, and it seams the Control Center has some unfulfilled dependencies and so it crashes...

• Windows Vista: Folder options not working

  - by Thomas Matthews

  I'm running Windows Vista Service Pack 2. I have the Folder Options set to "Open each folder in the same window." (Organize | Folder Options | General). Each time I open a folder, it opens in a new window. How do I get it to open each folder in the same window? I have tried the following techniques with no success: 1. Expand number of MBAG entries in Registry. (The number is 40,000 now.) 2. Delete Bags and MBAG entries in Registry. (Rebooted machine after, still no success). 3. Change to "Open each folder in its own window". Saved, then changed back. 4. Under View tab, changed "Remember each folder's view settings": unchecked, Apply to Folders, checked, Apply to folders. 5. Applied application from Annoyances.org. Still no success. 6. Clicked on Reset Default Options, then OK. (Opening in same fold is a default option!) Still unsucessful. I want the folders to open in the same window, just like the options say.

• NFS server generating "invalid extent" on EXT4 system disk?

  - by Stephen Winnall

  I have a server running Xen 4.1 with Oneiric in the dom0 and each of the 4 domUs. The system disks of the domUs are LVM2 volumes built on top of an mdadm RAID1. All the domU system disks are EXT4 and are created using snapshots of the same original template. 3 of them run perfectly, but one (called s-ub-02) keeps on being remounted read-only. A subsequent e2fsck results in a single "invalid extent" diagnosis: e2fsck 1.41.14 (22-Dec-2010) /dev/domu/s-ub-02-root contains a file system with errors, check forced. Pass 1: Checking inodes, blocks, and sizes Inode 525418 has an invalid extent (logical block 8959, invalid physical block 0, len 0) Clear<y>? yes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /dev/domu/s-ub-02-root: 77757/655360 files (0.3% non-contiguous), 360592/2621440 blocks The console shows typically the following errors for the system disk (xvda2): [101980.903416] EXT4-fs error (device xvda2): ext4_ext_find_extent:732: inode #525418: comm apt-get: bad header/extent: invalid extent entries - magic f30a, entries 12, max 340(340), depth 0(0) [101980.903473] EXT4-fs (xvda2): Remounting filesystem read-only I have created new versions of the system disk. The same thing always happens. This, and the fact that the disk is ultimately on a RAID1, leads me to preclude a hardware disk error. The only obvious distinguishing feature of this domU is the presence of nfs-kernel-server, so I suspect that. Its exports file looks like this: /exports/users 192.168.0.0/255.255.248.0(rw,sync,no_subtree_check) /exports/media/music 192.168.0.0/255.255.248.0(rw,sync,no_subtree_check) /exports/media/pictures 192.168.0.0/255.255.248.0(rw,sync,no_subtree_check) /exports/opt 192.168.0.0/255.255.248.0(rw,sync,no_subtree_check) /exports/users and /exports/opt are LVM2 volumes from the same volume group as the system disk. /exports/media is an EXT2 volume. (There is an issue where clients see /exports/media/pictures as being a read-only volume, which I mention for completeness.) With the exception of the read-only problem, the NFS server appears to work correctly under light load for several hours before the "invalid extent" problem occurs. There are no helpful entries in /var/log. All of a sudden, no more files are written, so you can see when the disk was remounted read-only, but there is no indication of what the cause might be. Can anyone help me with this problem? Steve

• Black Screen on Logon (windows 7 home premium)

  - by Blacknight334

  i have been having some trouble with a dell Xps 15 laptop that i recently purchased. it is under a month old, and a problem has occurred, upon logging on just after start up, the computer will just sit on a black log on screen (with the mouse still visible and active) for a few minutes. it is extremely annoying, especially when im in a rush. the laptop is under a month old. So far, i have tried to update the drivers, all windows update, and still, nothing. also, it doesnt seem to do it when i log into safe mode, or if it does, it will do it for less than 10 seconds, then load the desktop (in normal boot, it usually takes a few minutes). i have also run a number of the inbuilt diagnostics, but found no errors. i want to avoid having to do a system restore for as long as i can. does anyone know anything that can help? (the laptop is running a 500gb SSD, 2gb Nvidia 640m, 8gb ram, 3rd gen i7 quad core with 8 threads) thanks.

• Windows XP Setup Fails to Recognize USB Floppy after formatting AHCI disk

  - by Strahn

  I am attempting to install Windows XP Professional x64 onto a HP EliteBook 8540w. I have downloaded both the latest Intel Rapid Storage Technology drivers and the Intel Storage Matrix drivers that are listed on HPs website and copied the drivers over to a floppy disk (two separate floppies, one for each version of the drivers.) Booting to my WinXP Pro x64 install CD, I go through the F6 process, load the driver and am able to see my HDD, delete, create and format partitions on it. When I go to continue the install, after checking the disk, the system asks me to enter the disk labeled "Intel Rapid Storage Technology" and press enter to continue. Nothing happens at this point when I press enter. This happens if I use the latest drivers or the older drivers. We have created a slipstreamed install CD using nLite that has the AHCI drivers integrated, which installs fine. However, we have identified a number of issues with the system that I believe are side-effects of using nLite for the slipstreaming and I am attempting to verify that. I have researched this issue and found a few examples of others having the same problem, but no solution. The USB floppy is a Lacie branded floppy, connecting it to a working XP workstation shows it to be the Y-E Data USB floppy drive that is supposedly 100% compatible with XP per MS KB 916196.

• Windows 7 boot issues

  - by Michael

  Ok, I tried to install linux and dual boot my laptop with 7 ultimate. I messed up. When I tried to boot to 7 it said no. Something along the lines of device not found. So I being young and stupid I uninstalled linux which I could boot into, and I still could not boot to windows. Next step was to run the startup fixes from the boot cd. Swing and a miss, I also ran the fixmbr and fixboot. Which brings us up to my current place. I installed 7 again on my blank partition in hopes I could access my other partion. No dice. So my question to yall is how can I fix my original filesystem or at least get to the stuff on it. In the new 7 install the old partion does not even have a drive letter. That is my sad story any help would be apreciated.

• Perforce Proxy Server: Caching selective files [closed]

  - by fbrereto

  I just set up a Perforce proxy server for work. I'm noticing the cache directory is filling up very quickly -- with files I know I will never need. For example, there is a 'sandbox' directory in the depot where users keep personal branches and other work; a p4 sync is causing the p4 proxy cache to grab these user's sandboxes when I'll never need them. I would create a symbolic link for the sandbox directory to /dev/null but then I wouldn't be caching my sandbox, which I am interested in. Is there any way to tell the perforce proxy something to the effect of "if I haven't had to sync it, please don't cache it?"

• Cross-forest universal groups on Windows Server?

  - by DotGeorge

  I would like to create a Universal Group whose members are a mix of cross-forests users and groups. In the following example, two forests are mentioned (US and UK) and two domains in each forest (GeneralStaff and Java): For example, the universalDevelopers group may comprise of members from UK.Java.Developers and US.Java.Developers. Then, for example, there may be a group of universalSales which contains the users UK.GeneralStaff.John and US.GeneralStaff.Dave. In UK forest at the minute, I can freely add members and groups from the UK. But there is no way to add members from the US forest, despite having a two-way trust in place... e.g. I can login with US members into UK and vice-versa. A further complication is that, with a Universal group in the UK (which contains three domains), I can only add two of the three. It can't see the third. Could people please provide some thoughts on why cross-forest groups can't be created and ways of 'seeing' all domains within a forest. EDIT: This is on a combination of Windows 2003 and 2008 server. Answers can be regarding either. Thanks!

• Maintaining "Portability" Between Linux and Windows 7

  - by lokheart

  I am using the following ways in my office's Windows 7 machine to maintain my "portabilibity" when disaster strikes and I need to switch computer while I have no luxury of time for reinstalling all my program to the new PC. a majority of programs I used are portable, mostly from portableapp.com, like notepad+, GIMP, even R, I extract them and store them in a folder in My document, in a structure similar to the default portableapp installation when they are installed to a thumbdrive only a few software that portable version is not available and I will install them as usual all of my working files are stored in a folder in My document I regularly backup them all using syncback, because this program can keep versioning of my backup, and the backup is stored in a portable drive. One day I need to switch my computer and the operation is relative simple for me: I just move the two folders mentioned above into the my document folder of the new PC, install those few "non-portable" program in it, and this is almost done, some minor hiccups can be solved by reinstalling the portableapp into the drive. Overall speaking it is a smooth process. I would like to maintain the same degree of "portability" in my home Linux desktop (Ubuntu or Mint, I'm still deciding), that is, if my Linux crash and I need to reinstall it again. All I need to do is the move the two folder back to the new Linux, and most of my work will be almost ready to be worked on again. But I don't know how to find a Linux-alternative of portableapps. Being a newer to Linux, can anyone tell me whether this is possible in Linux?

• Tips for communication between JS browser game and node.js server?

  - by Petteri Hietavirta

  I am tinkering around with some simple Canvas based cave flyer game and I would like to make it multiplayer eventually. The plan is to use Node.js on the server side. The data sent over would consists of position of each player, direction, velocity and such. The player movements are simple force physics, so I should be able to extrapolate movements before next update from server. Any tips or best practices on the communications side? I guess web sockets are the way to go. Should I send information in every pass of the game loop or with specified intervals? Also, I don't mind if it doesn't work with older browsers.

• Nginx Restart Issues

  - by heavymark

  All of the sudden when restarting Nginx I get the following error: Restarting nginx: [alert]: could not open error log file: open() "/var/log/nginx/error.log" failed (13: Permission denied) 2011/02/16 17:20:58 [warn] 23925#0: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1 the configuration file /etc/nginx/nginx.conf syntax is ok 2011/02/16 17:20:58 [emerg] 23925#0: open() "/var/run/nginx.pid" failed (13: Permission denied) configuration file /etc/nginx/nginx.conf test failed On the front end part of the site loads but some files such as the CSS in particular are not loading. They exist on the server but when loading the resources directly in Chrome they say "Oops this page can't be found." I set a special group and user to run my apache files using suexec for my domain files. I think the nginx are owned by root however which I'm assuming is the problem but which nginx file ownerships would I change?

• OS X Server - setting up a share for network home directories + fast user switching

  - by sohocoke

  I'm nearly finished setting up my Open Directory master to allow users to be managed centrally and logged in on any of the client machines at home. I found discussion suggesting that using an AFP share for the 'Users' automount would result in network users (cf. users defined locally, or Portable Home Directory users) are unable to use fast user switching, as the first user logging in would trigger the automount and mount the 'Users' share with his permissions, preventing further users from using the mount. I've also found some suggestions to configure autofs such that the 'Users' share is mounted prior to any user logging in, but not great amounts of details along these lines. I'd greatly appreciate some instructions to set up autofs - ideally, on the OpenDirectory server rather than each client's etc/fstab or equivalent location, so that it isn't required per every client machine - to get fast user switching working with network users.
