• Using a portable USB monitor in Ubuntu 13.04 (AOC e1649Fwu - DisplayLink)

  Having access to a little bit of IT hardware extravaganza isn't that easy here in Mauritius for exactly two reasons - either it is simply not available or it is expensive like nowhere. Well, by chance I came across an advert by a local hardware supplier and their offer of the week caught my attention - a portable USB monitor. Sounds cool, and the specs are okay as well. It's completely driven via USB 2.0, has a light weight, the dimensions would fit into my laptop bag and the resolution of 1366 x 768 pixels is okay for a second screen. Long story, short ending: I called them and only got to understand that they are out of stock - how convenient! Well, as usual I left some contact details and got the regular 'We call you back' answer. Surprisingly, I didn't receive a phone call as promised and after starting to complain via social media networks they finally came back to me with new units available - and *drum-roll* still the same price tag as promoted (and free delivery on top as one of their employees lives in Flic en Flac). Guess, it was a no-brainer to get at least one unit to fool around with. In worst case it might end up as image frame on the shelf or so... The usual suspects... Ubuntu first! Of course, the packing mentions only Windows or Mac OS as supported operating systems and without hesitation at all, I hooked up the device on my main machine running on Ubuntu 13.04. Result: Blackout... Hm, actually not the situation I was looking for but okay can't be too difficult to get this piece of hardware up and running. Following the output of syslogd (or dmesg if you prefer) the device has been recognised successfully but we got stuck in the initialisation phase.

A quick and dirty research on the net gave me some hints towards the udlfb framebuffer device for USB DisplayLink devices. By default this kernel module is blacklisted $ less /etc/modprobe.d/blacklist-framebuffer.conf | grep udl#blacklist udlblacklist udlfb and it is recommended to load it manually. So, unloading the whole udl stack and giving udlfb a shot: Oct 12 08:22:31 iospc2 kernel: [70126.642809] usbcore: registered new interface driver udlfb But still no reaction on the external display which supposedly should have been on and green. Display okay? Test run on Windows Just to be on the safe side and to exclude any hardware related defects or whatsoever - you never know what happened during delivery. I moved the display to a new position on the opposite side of my laptop, installed the display drivers first in Windows Vista (I know, I know...) as recommended in the manual, and then finally hooked it up on that machine. Tada! Display has been recognised correctly and I have a proper choice between cloning and extending my desktop. Testing whether the display is working properly - using Windows Vista Okay, good to know that there is nothing wrong on the hardware side just software... Back to Ubuntu - Kernel too old Some more research on Google and various hits recommend that the original displaylink driver has been merged into the recent kernel development and one should manually upgrade the kernel image (and both header) packages for Ubuntu. At least kernel 3.9 or higher would be necessary, and so I went out to this URL: http://kernel.ubuntu.com/~kernel-ppa/mainline/ and I downloaded all the good stuff from the v3.9-raring directory. The installation itself is easy going via dpkg: $ sudo dpkg -i linux-image-3.9.0-030900-generic_3.9.0-030900.201304291257_amd64.deb$ sudo dpkg -i linux-headers-3.9.0-030900_3.9.0-030900.201304291257_all.deb$ sudo dpkg -i linux-headers-3.9.0-030900-generic_3.9.0-030900.201304291257_amd64.deb As with any kernel upgrades it is necessary to restart the system in order to use the new one. Said and done: $ uname -r3.9.0-030900-generic And now connecting the external display gives me the following output in /var/log/syslog: Oct 12 17:51:36 iospc2 kernel: [ 2314.984293] usb 2-4: new high-speed USB device number 6 using ehci-pciOct 12 17:51:36 iospc2 kernel: [ 2315.096257] usb 2-4: device descriptor read/64, error -32Oct 12 17:51:36 iospc2 kernel: [ 2315.337105] usb 2-4: New USB device found, idVendor=17e9, idProduct=4107Oct 12 17:51:36 iospc2 kernel: [ 2315.337115] usb 2-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3Oct 12 17:51:36 iospc2 kernel: [ 2315.337122] usb 2-4: Product: e1649FwuOct 12 17:51:36 iospc2 kernel: [ 2315.337127] usb 2-4: Manufacturer: DisplayLinkOct 12 17:51:36 iospc2 kernel: [ 2315.337132] usb 2-4: SerialNumber: FJBD7HA000778Oct 12 17:51:36 iospc2 kernel: [ 2315.338292] udlfb: DisplayLink e1649Fwu - serial #FJBD7HA000778Oct 12 17:51:36 iospc2 kernel: [ 2315.338299] udlfb: vid_17e9&pid_4107&rev_0129 driver's dlfb_data struct at ffff880117e59000Oct 12 17:51:36 iospc2 kernel: [ 2315.338303] udlfb: console enable=1Oct 12 17:51:36 iospc2 kernel: [ 2315.338306] udlfb: fb_defio enable=1Oct 12 17:51:36 iospc2 kernel: [ 2315.338309] udlfb: shadow enable=1Oct 12 17:51:36 iospc2 kernel: [ 2315.338468] udlfb: vendor descriptor length:17 data:17 5f 01 0015 05 00 01 03 00 04Oct 12 17:51:36 iospc2 kernel: [ 2315.338473] udlfb: DL chip limited to 1500000 pixel modesOct 12 17:51:36 iospc2 kernel: [ 2315.338565] udlfb: allocated 4 65024 byte urbsOct 12 17:51:36 iospc2 kernel: [ 2315.343592] hid-generic 0003:17E9:4107.0009: hiddev0,hidraw5: USB HID v1.10 Device [DisplayLink e1649Fwu] on usb-0000:00:1d.7-4/input1Oct 12 17:51:36 iospc2 mtp-probe: checking bus 2, device 6: "/sys/devices/pci0000:00/0000:00:1d.7/usb2/2-4"Oct 12 17:51:36 iospc2 mtp-probe: bus: 2, device: 6 was not an MTP deviceOct 12 17:51:36 iospc2 kernel: [ 2315.426583] udlfb: 1366x768 @ 59 Hz valid modeOct 12 17:51:36 iospc2 kernel: [ 2315.426589] udlfb: Reallocating framebuffer.

The external USB display works out-of-the-box with a Linux kernel > 3.9.0. Despite of a good number of resources it is absolutely not necessary to create a Device or Screen section in one of Xorg.conf files. This information belongs to the past and is not valid on kernel 3.9 or higher. Same hardware but Windows 8 Of course, I wanted to know how the latest incarnation from Redmond would handle the new hardware... Flawless! Most interesting aspect here: I did not use the driver installation medium on purpose. And I was right... not too long afterwards a dialog with the EULA of DisplayLink appeared on the main screen. And after confirmation of same it took some more seconds and the external USB monitor was ready to rumble. Well, and not only that one... but see for yourself. This time Windows 8 was the easiest solution after all. Resume I can highly recommend this type of hardware to anyone asking me. Although, it's dimensions are 15.6" it is actually lighter than my Samsung Galaxy Tab 10.1 and it still fits into my laptop bag without any issues. From now on... no more single screen while developing software on the road!

• How can find out the device Id of my unmounted DVD?

  - by fred.bear

  When I put a DVD into the DVD drive, it appears in Nautilus Places, but is not automatically mounted. (this is by personal choice). In this unmounted state, mount (of course) reports nothing, and likewise for df.. but Nautilus is aware of the DVD hardware unit and has read the Label; which it shows in Places So it seems to me that Nautilus has already accessed the DVD devices (Did it temporarily mount it?)... The main point of my question was to determine how to find the device Id of an unmounted device .. but as I've been writing this, I now think it may not be as simple as that... This issue came up because I wanted to test this command cat iso-pieces.* | growisofs -Z /dev/dvd=/dev/stdin, but then realized that I didn't know how to get my DVD's device Id. ... and does the above command requires a mounted device, or does it write directly to the device? ... as you can see, I'm a bit vague about devices :) Come to think of it maybe Nautalus read the DVD device directly, because when all is said and done, something has to read/write directly to it. info growisofs says: Under Linux it will most likely be an ide-scsi device such as "/dev/scd0 How can I find this Id via a script?

• ASA 5505 stops local internet when connected to VPN

  - by g18c

  Hi I have a Cisco ASA router running firmware 8.2(5) which hosts an internal LAN on 192.168.30.0/24. I have used the VPN Wizard to setup L2TP access and I can connect in fine from a Windows box and can ping hosts behind the VPN router. However, when connected to the VPN I can no longer ping out to my internet or browse web pages. I would like to be able to access the VPN, and also browse the internet at the same time - I understand this is called split tunneling (have ticked the setting in the wizard but to no effect) and if so how do I do this? Alternatively, if split tunneling is a pain to setup, then making the connected VPN client have internet access from the ASA WAN IP would be OK.

• A problem with connected points and determining geometry figures based on points' location analysis

  - by StolePopov

  In school we have a really hard problem, and still no one from the students has solved it yet. Take a look at the picture below: http://d.imagehost.org/0422/mreza.gif That's a kind of a network of connected points, which doesn't end and each point has its own number representing it. Let say the numbers are like this: 1-23-456-78910-etc. etc.. (You can't see the number 5 or 8,9... on the picture but they are there and their position is obvious, the point in middle of 4 and 6 is 5 and so on). 1 is connected to 2 and 3, 2 is connected to 1,3,5 and 4 etc. The numbers 1-2-3 indicate they represent a triangle on the picture, but the numbers 1-4-6 do not because 4 is not directly connected with 6. Let's look at 2-3-4-5, that's a parallelogram (you know why), but 4-6-7-9 is NOT a parallelogram because the in this problem there's a rule which says all the sides must be equal for all the figures - triangles and parallelograms. Also there are hexagons, for ex. 4-5-7-9-13-12 is a hexagon - all sides must be equal here too. 12345 - that doesn't represent anything, so we ignore it. I think i explained the problem well. The actual problem which is given to us by using an input of numbers like above to determine if that's a triangle/parallelogram/hexagon(according to the described rules). For ex: 1 2 3 - triangle 11 13 24 26 -parallelogram 1 2 3 4 5 - nothing 11 23 13 25 - nothing 3 2 5 - triangle I was reading computational geometry in order to solve this, but i gave up quickly, nothing seems to help here. One friend told me this site so i decided to give it a try. If you have any ideas about how to solve this, please reply, you can use pseudo code or c++ whatever. Thank you very much.

• Fast path cache generation for a connected node graph

  - by Sukasa

  I'm trying to get a faster pathfinding mechanism in place in a game I'm working on for a connected node graph. The nodes are classed into two types, "Networks" and "Routers." In this picture, the blue circles represent routers and the grey rectangles networks. Each network keeps a list of which routers it is connected to, and vice-versa. Routers cannot connect directly to other routers, and networks cannot connect directly to other networks. Networks list which routers they're connected to Routers do the same I need to get an algorithm that will map out a path, measured in the number of networks crossed, for each possible source and destination network excluding paths where the source and destination are the same network. I have one right now, however it is unusably slow, taking about two seconds to map the paths, which becomes incredibly noticeable for all connected players. The current algorithm is a depth-first brute-force search (It was thrown together in about an hour to just get the path caching working) which returns an array of networks in the order they are traversed, which explains why it's so slow. Are there any algorithms that are more efficient? As a side note, while these example graphs have four networks, the in-practice graphs have 55 networks and about 20 routers in use. Paths which are not possible also can occur, and as well at any time the network/router graph topography can change, requiring the path cache to be rebuilt. What approach/algorithm would likely provide the best results for this type of a graph?

• How do I use a jQuery not selector to select relative URLs?

  - by Matt

  I'm working on a little jQuery script to add Google Analytics pageTracker onclick data to all relative URLs on my forum, allowing me to track clicks to external sites. I don't want to add the onclick to internal links on forum.sitename or sitename, and I don't want to add them to any hrefs marked # or that start with /. My script below works nicely, but for one minor problem! All of the forum's URLs are relative and don't start with /. I appear to have no way to change that, so need to modify the jQuery below to prevent it adding the onclick to links like as it currently does. What I want to do, is to write a .not() function like .not("[href!^=http") to prevent jQuery from adding the onclick to any hrefs which do not start with http. However, .not() appears not to support this. I'm new to jQuery and can't figure this out. Any pointers would be massively appreciated. $(document).ready(function(){ // Get URL from a href var URL = $("a").attr('href'); // Add pageTracker data for GA tracking $("a") .not("[href^=#]") .not("[href^=http://forum.sitename]") .not("[href^=http://www.sitename]") .attr("onclick","pageTracker._trackEvent('Outgoing_Links', 'Forum', " + URL + ");") ; }); Thanks!

• Problem recreating BCD on Windows 7 64bit - The requested system device cannot be found

  - by Domchi

  NVIDIA drivers upgrade crashed my Windows 7 installation, so I'm working to undo the damage. What I can do: I can boot Windows install from the USB drive, and I can boot the Hiren's Boot CD. Although automated Windows repair fails, I can get to command prompt when I boot Windows install from USB drive, and I can see my drive and all my data. What I cannot do: I cannot boot into Windows - I get this message: Windows failed to start. A recent hardwware or software change might be the cause. To fix the problem: 1.insert windos cd and run a repair your computer option. File: /boot/bcd Status: 0xc000000f Info: an error occured while attempting to read the boot configuration data. It seems that something is wrong with my /Boot/BCD, so I'm trying to recreate it from scratch. I've tried all the methods detailed here (including Windows repair which fails), and I'm left with the last one (near the bottom of that page). When I type the following command as in the tutorial: bcdedit.exe /import c:\boot\bcd.temp ...it fails with the following error: The store import operation has failed. The requested system device cannot be found. Many Google results say that I must use diskpart to set my partition active, however it's already set as active. Also, when I try this: bcdedit /enum It fails with similar message: The boot configuration data store could not be opened. The requested system device cannot be found. Does anyone know what does that error message mean, and what is the requested system device? I'd like to avoid having to reinstall Windows since all the files on disk seem to be fine.

• sorry, the maximum allowed clients from your host (10) are already connected" FTP error

  - by Sejanus

  Hello, I keep getting the "sorry, the maximum allowed clients from your host (10) are already connected" error whenever I try to transfer a large number of files. At first I thought it's a filezilla bug, however I get the same error basically with every FTP client I've tried, including Total Commander under Wine. I do not get that error using Windows. I did try to limit maximum allowed connections for Filezilla, both in server settings and in global settings, it didnt change anything. I did try to switch between passive and active modes (not sure if it's related at all, just last desperate attempt), and it didnt change anything either. When I try to use native ftp client (not sure how is it called, the one in Places - Connect to a server) I get abstract "connection refused" error every time I transfer large number of files. Connection is refused for separate particular files, if I click "Ignore" each time the rest of files are transfered perfectly well, so I assume it's the very same error. Anything I could do? This really drives me mad, transfering large numbers of files is a part of my everyday job... P.S. and this happens with many different FTP servers. Also I dont get this error in Windows. So I assume it's not a server problem. P.P.S. I am aware of similar question here, the answer provided just didn't solve it to me.

• Swap partition not recognized (The disk drive with UUID=... is not ready yet or not present)

  - by ladaghini

  I think I had an encrypted swap partition, because I chose to encrypt my home directory during the installation. I believe that's what the line with /dev/mapper/cryptswap1 ... in my /etc/fstab is all about. I did something to bork my swap because on the next boot, I got a message (paraphrased): The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present. Wait to continue. Press S to skip or M to manually recover. (As a side note, pressing S or M seemed to do nothing different from just waiting.) Here's what I've tried: This tutorial on how to fix the swap partition not mounting. However, in the above, the mkswap command fails because the device is busy. So I booted from a live USB, ran GParted to reformat the swap partition (which showed up as an unknown fs type), and chrooted into the broken system to try that tutorial again. I also adjusted /etc/initramfs-tools/conf.d/resume and /etc/fstab to reflect the new UUID generated from formatting the partition as a swap. That still didn't work; instead of /dev/mapper/cryptswap1 not present, "The disk drive with UUID=[swap partition's UUID] is not ready yet or not present..." So I decided to start afresh as though I never had created a swap partition in the first place. From the Live USB, I deleted the swap partition altogether (which, again showed up in GParted as an unknown fs type), removed the swap and cryptswap entries in /etc/fstab as well as removed /etc/initramfs-tools/conf.d/resume and /etc/crypttab. At this point the main system shouldn't be considered broken because there is no swap partition and no instructions to mount one, right? I didn't get any errors during startup. I followed the same instructions to create and encrypt the swap partition, starting with creating a partition for the swap, though I think fdisk said a reboot was necessary to see changes. I was confident the 3rd process above would work, but the problem yet persists. Some relevant info (/dev/sda8 is the swap partition): /etc/fstab file: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.

• Why does Windows make random "device connect" and "device disconnect" sounds?

  - by Steve Elmer

  Hello, I've been noticing this since Windows Vista. I see it on Windows 7, now, as well. In any case throughout the day I notice that my computer makes apparently random device-connect and/or device-disconnect ("boink") sounds. I suppose it is the same sound you hear when connecting or disconnecting a USB device such as a thumb drive. I've noticed that this happens on each of three computers I work with at home, my wife's computer, and my machine at work. It happens without any user action at all - i.e. I'll be just sitting there (hands off my mouse and keyboard), and the computer will make the sound. There is no visual queue or anything. Just the sound. I have sometimes gone in pursuit of the sound - running virus scans, examining event logs and such, and observing task manager - but have never had any luck tracking this thing down, but have not had any luck. Surely someone else out there must be experiencing this, too. Any ideas? Thanks, Steve

• BIOS and Windows cannot detect CDROM device

  - by eman

  Hello! I have a HL-DT-ST RW/DVD GCC-4521B dvdrom device and a big problem. Some days ago everything worked fine. A friend installed some software and then the drives in winxp has been marked as corrupt. I uninstalled the software, but still corrupt drives. The next step I have done was running the current software GCC-4521B101(E).exe. When I ran this software again, the drives was automatically updated, but still marked as corrupt (in the Device Manager), even if I did a reboot. And then the big mistake: once more I tried to run this software, but during the update process, the machine restarted and boom! The DVDROM device doesn't work anymore. The led doesn't blink and if I push the eject button, nothing happens. Also bios and winxp doesn't recognize the optical drive. Then I plugged an other optical drive and it worked, but my old drive seems to be dead. So, what happened and how to solve this problem? Please help. Regards!

• Disable or remove filter driver for single HID device

  - by snoopen

  Running Windows XP in a corporate setting here. I have an issue where a filter driver is interfering with the functionality of different USB HIDs. For example graphics tablets do not respond while the filter driver is in place. I've also had the issue with foot pedals used with transcription software. My question is really two fold: A) what makes Windows use a filter driver on one HID but not another? B) when a filter driver is causing conflicts how can I disable it on the affected devices? Background I've previously narrowed down the issue to the filter driver by uninstalling the software (Funk Proxy Host) responsible for the filter driver. The software is a type of RDP we use here at work. (I might have even booted into safe mode and renamed the file, I forget). I believe the filter driver is present to disable or modify the use of the local keyboard and mouse while admin staff are assisting users. Either way I don't have the authority to just go uninstalling this software. As far as I can tell the software versions are the same, however I'm not sure if the device driver definitions are all the same as I don't know where these things would be located. To check for the presence of the filter driver I locate the hardware device in Device Manager, click Properties Driver tab Driver Details.... It shows up as ph32ihid.sys. Even though all machines are meant to have the same SOE and do have Funk Proxy Host installed I don't always have issues with the same HIDs. A few machines here the foot pedals without any issues. I've not had any machines work with the graphics tablet without uninstalling Funk software. Driver details I've just read up a bit more about filter drivers and found the drivers description in the registry under "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ProxyHostHIDFilter" There it's called "Kernel-mode HID filter driver for the Proxy Host". Presumably I could also disable it here but that would be system wide which is probably not desirable?

• Use old raid drive as boot device without data loss

  - by Gabriel

  There were two disks in sw-raid. There were /dev/md1 as swap, /dev/md2 as boot and a /dev/md3 with ext4. The sw-raid was disabled by stopping and removing mdadm and then zeroing the superblock on each /dev/mdX partition with: sudo mdadm --zero-superblock /dev/sda1 sudo mdadm --zero-superblock /dev/sda2 sudo mdadm --zero-superblock /dev/sda3 In the disk that is the first boot device, I don't know if it's relevant, the system type of each partition was set back from fd to 82 or 83 with fdisk, /etc/fstab was updated, changing /dev/mdX to /dev/sdaX, and grub was reinstalled on the boot partition (/dev/sda2) with grub-instal. But the system wont boot. What else should I do to use this disk as the boot device without reinstall or data loss? Current output of fdisk Device Boot Start End Blocks Id System /dev/sda1 2048 33556480 16777216+ 82 Linux swap / Solaris /dev/sda2 * 33558528 34607104 524288+ 83 Linux /dev/sda3 34609152 3907027120 1936208984+ 83 Linux With it doesn't boot I mean that it stops in the grub console (with the grub> symbol).

• Take a regular Windows 7 clone with clonezilla (device-to-image)

  - by Mario De Schaepmeester

  I am unexperienced with cloning software and I've decided to use Clonezilla as it seemed best as freeware. I chose device image and left most options standard. I chose expert mode anyway to see what I could configure, and decided to try the lzop algorithm instead of the default one for compression. The rest was left at default. When Clonezilla asked me which partitions to clone (I chose parts to image), I chose the C:\ drive but Windows 7 also creates a 100MB partition on setup for system files (the actual boot partition?). I copied that into the image as well. The reason I didn't choose disk to image is that I also have a data partition that needs to stay intact. Now I'm simply not sure that this is the way to go, should I ever need to restore my disk image. Will Clonezilla know what to do with both partitions and will Windows 7 work perfectly after restoring? Edit: apparantly a similar question has been asked before. The link to the first article in the answer is not relevant to me since it covers a device-to-device clone. It appears the windows installation disk can repair the 100MB partition. As for Clonezilla, it copies "hidden data after the MBR" by default too. I don't know, I feel I'll be allright whether by restoring the partition with Clonezilla or repairing it with the Windows 7 disk.

• How to fix Windows 7 device removal notification loop

  - by Barry Kelly

  Bit of an odd one this. One of our PCs is getting caught in a loop some time after being turned on, usually after a USB storage device has been attached - sometimes an iPod, sometimes a GPS. Specifically, Windows Explorer starts showing a drive icon and letter (E:, as of right now) for the System partition (the small hidden one at the start of the boot drive). Then, the icon disappears. Then it reappears again. And disappears. It does this very quickly, at what looks like maybe 50 times a second. CPU usage in this loop is also very high; averages about 66%. This machine has an i7 920 CPU, which is quad core with hyperthreading; so this usage rate works out to about 5 100% busy threads, along with whatever normal idle load is (particularly Task Manager itself). Inspecting with Process Explorer shows that the device removal notification infrastructure has gone berserk. The threads in system service processes (i.e. apart from Windows Explorer) which are using all the CPU power relate to device notification. The Disk Management MMC snap-in also fails to run when the loop starts. The only way to break the loop, it seems, is to reboot the machine. Anyone seen anything similar to this, and know of a way to fix it? Machine details: Windows 7 x64, fully patched i7 920, 12GB RAM Intel SSD 80GB (X25-M, I believe; not G2) 2TB 5.2K disk for bulk storage AMD HD 5870 Further hardware details await. I'm going to go through and update all drivers I can find.

• Changing default gateway on workstations connected to Windows Domain SBS server

  - by Gary B2312321321

  We have xp workstations connected onto a small business server acting as active directory/isa firewall/proxy (no dhcp). Is there a reason that after installing a 2nd firewall on the network (same subnet etc), that changing the default gateway on the workstations isnt sufficient to route inet traffic through the new firewall? A freshly setup linux box connects straight on to the alternate firewall with just ip, default gateway. dns settings. Will having ISA still active on the network confuse the process? Are there further config settings deeper down in windows that need attention? Any ideas pointers on this would be appreciated? Other info: Firewalls tried: Smoothwall and Ipcop; small ethernet netwoork 40 pcs; can ping to new firwalls from workstations; activating web proxy on new firewall and reconfiguring workstation browser works fine; Point of 2nd firewall is lack of some necessary features on ISA for a linux app; Would be nice to have some redundancy to though

• USR9108 not connecting to DSL service/not detecting carrier

  - by Salman A

  As suggested in this answer I've hooked up the phone cable to the USR9108 router. I've entered the information provided by the ISP (VPI/VCI, Username, Password etc) in the ADSL configuration section but the router does not connect to DSL service. The ASDL diagnostics fail in the first step stating that no signal was found. The same phone line when connected to ZyXEL P-660R-T1 v2 modem works successfully. Can anyone tell me how to trouble shoot this issue? Does it have something to do with 2 wire and 4 wire telephone line? PS: whats the difference between ASDL and DSL?

  I have a Toshiba Satellite A505-S6014 laptop running Windows 7 64-bit connected to a Toshiba Regza 42" HDTV with an HDMI cable. The laptop has a 16" display and the screen resolution is set to the maximum/recommended of 1366x768. The display output is set to "LCD+HDMI". The display looks fine on the laptop screen but on the TV it is not a "full screen" display, it leaves a good 3" black border all around all 4 edges. When I switch the display to "HDMI only", it is now too big for the TV screen and some of my desktop icons are no longer visible off to the side. What is the best way to set this up? I guess that since a 16" and 42" displays have different native resolutions, a LCD+HDMI mode is defaulting to the optimal size for the 16". But when I set it to HDMI Only, what is the appropriate resolution for a 42" full screen display? Thanks

• Robocopy to a drive connected to a wlan router fails

  - by Ville Koskinen

  I have a wireless router and an USB hard drive connected to it. Basic file access on the command line and Explorer works flawlessly after having set up some options on the router and mapping to some folders with net use k: \\ROUTER\Folder1 /user:MYLAPTOP\Me password /persistent:yes net use n: \\ROUTER\Folder2 /user:MYLAPTOP\Me password /persistent:yes Robocopy (and using SyncToy for that matter) to a network drive however fails: robocopy c:\Files k:\Backup /MIR /Z gives There is not enough space on the disk. 2010/01/05 09:52:11 ERROR 112 (0x00000070) Accessing Destination Directory N:\ Waiting 30 seconds... The error message is misleading: there is plenty of space on the disk and the folders I'm copying are small. The router is an ASUS WL-500gp with a standard firmware. I'd appreciate if someone would be able to explain what is causing the problem and, if possible, how to fix it.

• Serial number not found, copy of Windows not genuine

  - by sara

  I have an HP-G71-340US notebook that I purchased 11/29/09. When I power it up, a black screen comes on that shows "serial number not found" and it also says that my copy of Windows 7 Home Basic is not genuine – but my computer came with Windows 7 Home Premium. In BIOS, my serial number is not shown either and I did pull out the little battery to reset it which allowed me to bypass the suddenly new locked BIOS that needed a password to enter. I'm sure this is a masterpiece created by my 6 or 9 yr old child while trying to play on my laptop. Can I fix these two problems?

  I have Macbook Pro with OSX 10.6.8. It is connected to external display (HP 2311x) using Thunderbolt to HDMI cable. My Macbook display goes to sleep after every 15 minutes of inactivity but the external display won't go to sleep. It does try to go to sleep but wake up immediately. It does that in never ending loop. I have to manually turn off the external display. Is there some settings I need to change to make external display sleep when Macbook display goes to sleep?
