  • Files and folders disappeared from my desktop

    - by Rob
    Suddenly all files, folders and icons that were on my desktop have disappeared. tried making "show hidden files", no luck. tried using recovery software, but it did not find any of this files, so I assume they were not deletes. c:/Users/<myname>/Desktop does look empty from the Explorer, as well as from cmd. installed MalwareBytes, it did find and remove some malware, but it didn't seem to help. used RogueKiller and it did find some suspicious registry called "HideDesktopIcons". ¤¤¤ Registry Entries : 4 ¤¤¤ [HJ DESK] HKCU\[...]\ClassicStartMenu : {59031A47-3F72-44A7-89C5-5595FE6B30EE} (1) -> REPLACED (0) [HJ DESK] HKCU\[...]\NewStartPanel : {59031A47-3F72-44A7-89C5-5595FE6B30EE} (1) -> REPLACED (0) [HJ DESK] HKCU\[...]\ClassicStartMenu : {20D04FE0-3AEA-1069-A2D8-08002B30309D} (1) -> REPLACED (0) [HJ DESK] HKCU\[...]\NewStartPanel : {20D04FE0-3AEA-1069-A2D8-08002B30309D} (1) -> REPLACED (0) I deleted this registry, rebooted, it only unhid My Computer and User icons, but my desktop stuff is still missing — any ideas what should I do next?

  • Cannot access to any windows share including localhost

    - by user21936
    I can't access any share from my operating system, including \\localhost and \\127.0.0.1. I have Windows 7. NetBIOS over IP is enabled, other computers in the network can access my shares and other computer's shares, but my operating system cannot access any share. I have installed Windows XP within VMware, and the virtual windows xp can access all shares including the host shares. I can communicate in other ways like TCP, HTTP and gaming, but not access shares. How to solve this problem?

  • Google Chrome giving error 138

    - by gsingh2011
    Google Chrome randomly stopped working one day and is giving me this error: Google Chrome is having trouble accessing the network. This may be because your firewall or antivirus software wrongly thinks that Google Chrome is an intruder on your computer and is blocking it from connecting to the Internet. Here are some suggestions: Add Google Chrome as a permitted programme in your firewall or antivirus software's settings. If it is already a permitted programme, try deleting it from the list of permitted programmes and adding it again. Error 138 (net::ERR_NETWORK_ACCESS_DENIED): Unable to access the network. I didn't make any changes to my firewall settings between the time it was working and when it wasn't working. I'm using the default Windows Firewall. I added Chrome to the allowed programs and restarted, but that didn't fix the error. I even reinstalled Chrome completely and that didn't work either. Any help would be appreciated. EDIT: I forgot to mention that Firefox and IE9 work fine.

  • Using onboard and pci-e graphics card at the same time

    - by Endle
    Hello wonderful people. I know there are several other posts with similar questions. I also know how to use Google. I also have read up on posts discussing bumblebee, crossfire, ati catylist and many other interesting topics. I would just like someone to give me advice on how to use the onboard and pci-e graphics at the same time. I know the computer is capable of doing this. It works in Windows. I can use the VGA and DVI onboard port and the HDMI port of the add on card all at the same time. Works great in Windows 7, In Ubuntu, it seems only one or the other will work. I can use any combination of two displays on either adapter: VGA and HDMI..HDMI and DVI..so forth and so on. I have started experimenting with xorg.conf files, but have not been able to get any of them to work. Here is my last attempt at writing an xorg.conf file: Section "ServerLayout" Identifier "X.org Configured" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" LeftOf "Screen0" Screen 2 "Screen2" LeftOf "Screen1" InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "Device" Identifier "Onboard Video" Driver "radeon" BusID "PCI:01:05.0" EndSection Section "Device" Identifier "Graphics Card" Driver "radeon" BusID "PCI:02:00.0" EndSection Section "Monitor" Identifier "CRT2" Option "VendorName" "ViewSonic" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Monitor" Identifier "DVI1" VendorName "ACR" ModelName "P224W" Option "DPMS" EndSection Section "Monitor" Identifier "DVI2" Option "VendorName" "Acer" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Screen" Identifier "Screen0" Device "Onboard Video" Monitor "CRT2" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1280x1024" EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Graphics Card" Monitor "DVI1" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1920x1080" EndSubSection

  • How computers display raw, low-level text and graphics

    - by panic
    My ever-growing interest in computers is making me ask deeper questions, that we don't seem to have to ask anymore. Our computers, at boot, as far as I understand it, are in text mode, in which a character can be displayed using the software interrupt 0x10 when AH=0x0e. We've all seen the famous booting font that always looks the same, regardless of what computer is booting. So, how on earth do computers output graphics at the lowest level, say, below the OS? And also, surely graphics aren't outputted a pixel at a time using software interrupts, as that sounds very slow? Is there a standard that defines basic outputting of vertices, polygons, fonts, etc. (below OpenGL for example, which OpenGL might use)? What makes me ask is why OS' can often be fine without official drivers installed; how do they do that? Apologies if my assumptions are incorrect. I would be very grateful for elaboration on these topics!

  • How to force Windows to call the partition it installs on C:?

    - by maaartinus
    I'm going to install Windows XP from a CD and want to make sure it calls the partition it lands on C:. The target partition is the first one on a SATA disk, which is not the first one in my computer. There's no IDE disk there. I don't think I can swap the disks, as I'm using a fake RAID and really don't want to get problems with it. The target partition is on a normal disk. I know it may be unimportant, but I don't want to run in any problems I can avoid. I've seen a question slightly related to it, but I'm not going to install from a USB.

  • Ubuntu 12.04 takes too long to boot

    - by msPeachy
    I've recently encountered the following error message: mount: mounting /dev/disk/by-uuid/3f7f5cd9d-6ea3-4da7-b5ec-**** on /root failed: Invalid argument mount: mounting /sys on /root/sys failed: No such file or directory mount: mounting /dev on /root/dev failed: No such file or directory mount: mounting /sys on /root/sys failed: No such file or directory mount: mounting /proc on /root/proc failed: No such file or directory Target file system doesn't have /sbin/init. No init found. Try passing init= bootarg. Busybox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) _ I run sudo fsck /dev/sda2 which is the Ubuntu ext4 root partition via LiveCD. It checked and fixed the file system. The next time I boot, Ubuntu started to load with the Ubuntu logo and the dots underneath for several hours (with the mouse pointer active on the screen), I even let the computer on overnight but still it did not successfully boot or got to the login screen in the morning. I booted again with the LiveCD and checked the NTFS partitions with ntfsfix and again the NTFS partitions was checked and fixed successfully. I also edited my fstab and commented out the lines that auto-mounts the NTFS partitions. The next time I boot, it took almost 20 minutes for Ubuntu to get to the login screen, after typing the password it took an additional 10 minutes for Ubuntu to get to the desktop. On the desktop, it take several minutes to open any program, displaying the Dash alone takes 5 minutes! Is there a fix for this without having to reinstall Ubuntu? I don't see or get any errors, Ubuntu is just taking too long to boot and to run programs. Please help!

  • Installing any linux distro on new netbook hangs midway

    - by Neigyl R. Noval
    I have just bought a new netbook, Lenovo S110 with a starter Window 7, 32 bit Operating system. I wanted to wipe away Windows and go with Debian or Ubuntu. I have successfully made my USB drive bootable with the Debian net install. The problem is, my computer always hangs up at the start of the installation (with the latter shown on screen). Keyboard stopped responding , and USB was probably not reading (since it was not blinking anymore). I know the bootable USB drive with Debian installer is working since installation works on other netbooks. What should I do to install Linux on my netbook?

  • Why is my disk full?

    - by Agmenor
    I installed Ubuntu 12.04 by doing a fresh install where there was previously Ubuntu 11.10. My computer warns me now that my disk is nearly full. After having run apt-get purge, run apt-get autoremove and emptied the Trash can, I still have this problem as shown by this screenshot of Gparted: The disk /dev/sda7 is indeed full. I ran the Disk Usage Analyzer (Baobab) and I am still not sure of what is happening: One of my hypothesis is that when installing Ubuntu 12.04, I didn't configure my disks well and the disk /dev/sda6 is not mounted well as /home. Is this the reason indeed? What should I do to verify this and then to get the things fixed? Here are a few additional details to answer the questions I received (thank you everybody): My home directory is not encrypted. The Backup utility (Déjà Dup) is not set for automatic backups. (I do it myself and manually.) After I mount /dev/sda6, the command df -h gives Filesystem Size Used Avail Use% Mounted on /dev/sda7 244G 221G 12G 96% / udev 3,9G 4,0K 3,9G 1% /dev tmpfs 1,6G 904K 1,6G 1% /run none 5,0M 0 5,0M 0% /run/lock none 3,9G 164K 3,9G 1% /run/shm /dev/sda6 653G 189G 433G 31% /media/8ec2fa69-039b-4c52-ab1b-034d785132a1 (sorry but formatting this into code does not work, for an unknown reason) Thanks to izx's post, I realized /dev/sda6 was not even mounted before. It contains all the documents I used to have when I was running Ubuntu 11.10.

  • Random compositing lag

    - by user1020567
    My laptop specs: 512 mb of RAM, out of which 64 mb are shared with an integrated GPU - ATI Radeon Xpress 200 M. Intel 1,6 Ghz Celeron M single-core processor. I've spent months trying to figure out why compositing and effects sometimes lag on any distro I try. Now I've come to realise that no matter what drivers I try (the default ones work for me on pretty much any linux) compositing lag is random. When I used Ubuntu 10.10, for example, sometimes window compositing would lag and sometimes it wouldn't. The PC is able to render those effects so hardware is not the problem. It's completely random and unpredictable - sometimes when I turn on the computer the effects lag horribly and sometimes it's completely smooth. I've also checked startup items and there doesn't seem to be any unnecessary entries. I also tried building my own OS with Arch Linux and the problem persists there, therefore I can only assume that it's a driver issue of some sort. By default there are lots of drivers supplied with linux distributions. Could it be that they're in the way? The ones that I need are ati/radeon (or both? What's the difference between them?) and there seem to be a lot of others... What should I do?

  • Where can I find more information on "Kinds of Information Systems" [on hold]

    - by arielnmz
    Disclaimer: This is not a Power User question, but rather more of the Computer Enthusiasts kind. Also, I don't know the right site to post this kind of question. I'm writing a paper in which I am asked to mention and describe "5 types of information systems" to which my teacher explained: Like Web, Mobile, etc…, for example… He also said that we're not able to mention and describe those mentioned above. So the question is: What is the right topic to research or look into for more information about these different types of "information systems"?

  • Can I remotely monitor printf results of a C program?

    - by Mota
    I have a long running C program in which I've started from the Terminal.app using: gdb program_name gdb run I'm using many printf statements to monitor the progress of the program. Unfortunately, the screen of the computer has been frozen since yesterday, but the process is still running. My question is, can I watch the progress of the program (i.e. the results of the printf statements) remotely? I'm not that familiar with the terminal, but I know how to ssh and do some simple terminal tasks. The OS of the machine with the frozen screen is Mac OS 10.6.

  • Can Grub be configured to remember the last OS you booted into?

    - by Matthew
    I typically have 2-3 OSes in my boot menu: Ubuntu 10.04 Windows 7 [Sometimes, a third option, such as Ubuntu 10.04 Netbook] If I am in an OS other than the default choice (Windows 7 in this case), and I reboot, Grub boots into Ubuntu 10.04. This shouldn't happen--when I reboot in Windows 7, I want to stay in Windows 7. Is there any way to configure Grub to remember my last choice, and boot into that? Alternatively, it would be even better if Grub only did this when I rebooted (not when I first turn the computer on). I realize this may not be possible, so I'd be happy with simple last-choice-remembering.

  • Weird files in User folder

    - by Vervious
    In my user folder (C:/Users/myAccount/) theres a set of interesting hidden files that I've never seen before (right now it's a fresh install of Windows 7 Ultimate). These are: NTUSER.DAT, ntuser.dat.LOG1, ntuser.dat.LOG2, and NTUSER.DAT(whole chain of numbers and letters).TM.bif, NTUSER.DAT(whole chain of numbers and letters).TMContaineretcetc.regtrans-ms, and another similar one. When I try to delete them, it says the system is using them. I've never seen these files before. Are they ok to delete? Or should I leave them in my home folder? I always keep "Show hidden files" as well as "Show System files" checked, since I prefer being able to see all the files on my computer. If I shouldn't delete them, is there at least a way to tidy them up a bit? Thanks.

  • How do I fix my ethernet card losing network connection every few minutes with kernels 3.8.x?

    - by igoryonya
    I'm using Ubuntu 13.04. My laptop is Acer Aspire one 722-c58rr, and my ethernet card works for a few seconds at a time with kernels 3.8.x, however, kernels 3.5.x and below worked fine. On kernels 3.8.x, it works fine after boot for about a minute, then it looses network connection. When pinging to some address, it says: network address is unreachable, but it can ping it's own address. The address is statically configured. Everything was working fine before. I went to vacation, where I used WiFi and 3G connections, so I didn't notice that the problem occurred. Came back home, plugged in into the ethernet. It worked for a minute then stopped. Rebooting commutator fixed the problem. Tried to connect to a different commutator, same problem. Unplugging and plugging the cable fixes the problem for another minute. Disconnecting eth in Network manager and reconnecting it again, does the same thing. WiFi has no such problem. Tried to use a different cable that works fine on another computer, the same problem. Tried to boot with the lower kernel version, the same problem was happening until I got to the version 3.5 of the kernel series. Everything works fine on the kernel 3.5.x, but I don't want to miss out on the new kernel's features. Executing commands, when booted with 3.8 kernel series, give the following results: lspci| grep -i eth: 06:00.0 Ethernet controller: Qualcomm Atheros AR8152 v2.0 Fast Ethernet (rev c1) dmesg| grep eth1: [ 89.548291] atl1c 0000:06:00.0: atl1c: eth1 NIC Link is Up How do I fix it, while staying in the new kernel version?

  • After upgrade to Windows 8.1, no Skydrive icon in task bar

    - by Jeremy Butler
    I upgraded to 8.1 and now I don't see the SkyDrive icon in the task bar, nor the green light under it indicating the my computer is communicating with SkyDrive. When I go into Control Panel |..|Notification Area Icons, SkyDrive is listed and noted as Up to date. However even though I mark it to Show Icons and Notifications I don't see any icon in the taskbar. Is it supposed to be this way, or do I have a problem? I kind of got used to that little green synchronizing indicator giving me a warm and fuzzy feeling.

  • Can't login to Unity 3d after enabling Xinerama for a short moment

    - by Amir Adar
    Today I connected a second monitor to my computer. I set it up using nVidia's control panel, and all was working quite well, so I figured it won't be a problem to try Xinerama, just to see the difference between that and twinview. After enabling Xinerama and restarting the X session, I saw that I was logged into a Unity 2d session. I thought it was a problem with Xinerama, so I switched back to twinview, but it still logged me into Unity 2d. I tried disconnecting the second monitor, no luck: still Unity 2d. I tried changing GPU drivers and installing drivers from a separate ppa, and still I was logged into Unity 2d. Up until this point, I didn't have any problem logging into Unity 3d. It only happened after I tried using Xinerama. I should note that I was doing all this while updates were going on in the background, so it could be something related to that, though I can't imagine what (I tried booting with another kernel, but no luck). So what exactly happened? Did changing the mode to Xinerama triggered some other changes that I'm not aware of? Did these updates cause a certain malfunction in the driver? Is it something else?

  • How do I troubleshoot system slowness seen when viewing PDFs or videos?

    - by asp
    Whenever I watch videos, either online of local via Totem and/or open PDF files using evince. The system gets really, really bogged down. All apps get really slow, menus take forever to display, switching windows gives me time to make a coffee, etc. I have a couple of bug reports open on this, but what do I need to do to really troubleshoot the issue? I've purged Adobe Flash from the system, but YouTube HTML5 videos still have the issue. A bunch of PDFs saved locally trigger the problem. And to (temporarily) remove the slowness, I need to shutdown the computer, breath for a few minutes, then restart. A simple reboot does not do the trick. How can I identify the cause? This only started on 13.04. I've had Ubuntu on this machine for a year without a problem until "upgrading" to 13.04. I am not a programmer, but I suspect an issue with the Intel video driver. Is there something I can run which will diagnose this, or are there concrete steps I can follow to find the culprit?

  • Why does booting from a 64 bit Win 8 USB install work on a 32 bit laptop?

    - by Arabella
    I upgraded a 64 bit Windows 7 laptop to Windows 8 through the Upgrade Assistant, creating a bootable USB without any problems. I installed it successfully. Before I purchased an upgrade for my 32 bit Windows 7 laptop, I decided to boot from the USB with the 64 bit ISO to see what happened. The Windows 8 install screen came up with all the options. Should it not have detected that the laptop is 32 bit and therefore the install should have given an error? I cancelled the install before it did anything, but now I want to know if I need to download the iso again after purchasing the upgrade on my 32 bit laptop? I've read the answers to this question, which confirms what is said in this article - a 32 or 64 bit iso will be downloaded depending on the hardware of the computer you are upgrading. If that is the case, then why did it boot into the install screen?

  • If a change the CPU, must I reinstall the OS?

    - by dag729
    Hi, as suggested by the title, I want to change CPU: actually I have two computers, one with Ubuntu running on an AMD Athlon 64 dual core 5200+ and the other with FreeBSD running on an AMD Sempron single core LE-1250. I would like to swap (I am not sure that this is the correct term...) the CPUs from one computer to the other one, that is take the dual core from the ubuntu pc and put it inside the freebsd pc and viceversa. The mobo is the same. Do you think I will encounter problems?

  • Installing Oracle11gr2 on redhat linux

    - by KItis
    I have basic question about installing applications on linux operating system. i am going to express my issue considering oracle db installation as a example. when installing oracle database , i created a user group called dba and and user in this group called ora112. so this users is allowed to install database. so my question is if ora112 uses umaks is set to 077, then no other uses will be able to configure oracle database. why do we need to follow this practice. is it a accepted procedure in application installation on Linux. please share your experience with me. thanks in advance for looking into this issue say i install java application on this way. then no other application which belongs to different user account won't be able use java running on this computer because of this access restriction.

  • Wifi won't connect to certain networks

    - by Dave M G
    As I write this, I'm in a coffee shop on my laptop, and I am trying to connect to the free wifi network they offer. Every time I select their network from the wifi applet drop down menu, it connects for a second and then disconnects. At the same time, I have my Android phone with me, and it connects to the coffee shop's network without problem. There are a couple of people around me also using the same network with no issues. I asked the staff to check and as far as they can tell there is no problem with their router or anything. I have tried rebooting, but it has not made a difference. I have double and triple checked that I am using the correct WEP password. As an added wrinkle, when I connect to another network, it seems to connect (although I can't use them because they are paid gateway services). So I'm able to ask this question now because I have tethered my laptop to my phone, but it's slow and a workaround, not a solution. All indications are that it's a problem with my computer against this one network. Why would that be and how can I fix it?

  • When I plug an HDMI cable into my MacBook Pro with Retina Display, the resolution of the retina display changes

    - by Tyler Crompton
    I had an HDMI cable plugged in for a while that connected to a TV with no power. The retina display randomly flashed blue after a while and then changed to a different resolution (possibly 1080p). I unplugged the HDMI cable and nothing happened. So I restarted the computer to no avail. I was still having issues. So I fiddle with some settings after plugging in the HDMI cable again. Now, the retina display appears fine when no HDMI cable is plugged in, but when there is one plugged in, the resolution changes. I have mirroring turned off (which is what I want). The resolution of the retina display when an HDMI cable is plugged in is 3,360px x 2,100px (according to the size of a screenshot) and the external display is 1,600px is 900px. How can I fix the retina display to show with the correct resolution.

  • Is anyone else having issues with opening app links on iOS6 iPad3?

    - by lindon fox
    Links to ios apps (to the app store) are not working for me on my iPad 3/iOS 6. I thought it was my code causing the problem initially, but then I tried it on an iPhone, and an older iPad 2 and they both worked. I looked into it further and it seems no links are working (that I can find). I have googled, but I have not found anything yet. Is there anyone else having this problem? Example: link - this link will work on my computer and phone, but not on my iPad3 running iOS6 - it will just bring up the app store app showing the main screen.
