  • Input Signal Out of Range 1920x1080

    - by Zach
    I've recently installed Ubuntu 12.04 on my computer. Now, every time I boot and when I shut down, my monitor goes blank and says "Input Signal Out of Range - Change Setting to 1920x1080 60Hz." Once the computer gets to the login screen, it's okay again. This problem also happens when I try to open any 3d app. My graphics card is NVIDIA GEforce 6150 SE. I tried updating the drivers, but it broke everything and I had to reinstall Ubuntu. Any help?

  • How Hackers Can Disguise Malicious Programs With Fake File Extensions

    - by Chris Hoffman
    File extensions can be faked – that file with an .mp3 extension may actually be an executable program. Hackers can fake file extensions by abusing a special Unicode character, forcing text to be displayed in reverse order. Windows also hides file extensions by default, which is another way novice users can be deceived – a file with a name like picture.jpg.exe will appear as a harmless JPEG image file.

  • Mouse permanently stuck on left side of screen

    - by Alex
    One of my two monitors is died, so while my computer was turned off I unplugged the dead monitor then turned my computer back on. When I got to the log in page I typed my password and got to the desktop my mouse was stuck to the left edge of the screen. I can move it up and down, and left and right click, but it won't come off the edge. I tried switching the monitor cable to the other slot to see if that would make a difference but nothing changed. If it makes a difference, I'm using Kubuntu.

  • Getting "boot error" when trying to boot from USB

    - by Jon Ball
    I'm wanting to try out Ubuntu, so followed the instructions for how to install Ubuntu onto a USB. I downloaded the .iso file, then the pendrivelinux 3 part process to make the USB bootable. I can see what looks like a full list of files on the USB (including the wubi.exe application and the syslinux folder). When I try to restart the computer with the USB in, I get the Dell start up screen, and then a black screen with "Boot Error" in the top right hand corner. Setup options (default) are to boot from Removable Device, then Hard Disc. USB is brand new, straight out of the packet. Computer: Dell Inspiron 530S BIOS: 1.0.13 OS: Windows Vista Home Edition USB: EMTEC 8Gb, formatted to FAT32 I've tried some of the tips in other help topics (holding down CTRL key while restarting, removing all other USB devices). I tried to reformat the USB to something other than FAT32, but my only other options were NTFS or exFAT (not FAT16 which was suggested in another topic).

  • Timeout when trying to install ubuntu 12.04

    - by Oskars
    When i click on "try ubuntu" after booting it from a USB the screen goes black and a lot of text comes out. But after a while it says "timeout: killing /blablabalba" or something like and it just keep on saying that. What have I done wrong? <.< My computer is a Acer ASPIRE M5201 if that is of any importance. Edit: I noticed now that before it says "timeout" it says something about not supporting "DNS" or "Asn" or something like that. I'm not sure if it was exactly dns and asn but do this mean that I can't run ubuntu on this computer? Edit2: The exact strings are: "[sdg] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA " "timeout: killing '/sbin/modprobe -bv pci:v00001002d00"(and more nubmers wich I didn't catch)

  • What You Said: Giving an Old Laptop a New Life

    - by Jason Fitzpatrick
    Earlier this week we asked you to share your tips and tricks for breathing life into an old laptop, now we’re back to share your junk-bin sparing methods. Many of you worked to keep old laptops from getting scrapped by dusting them off and donating them. Mark writes: My acquaintances & friends give me their old computers when they buy a new one. So I disassemble, clean, install an opsys,and get internet working. I also upgrade memory, wireless, etc. from my parts bin. Then I give it to a poor person who needs a computer. Usually a single working mom with kids. I also do the same with old desktops as well. They really appreciate them and It gives me the satisfaction of resurrecting an old computer.

  • Ubuntu will not start due to full partitions

    - by mike
    I left my computer downloading all the night and I did download 35 GB of movies (legal ...). I restarted the computed in the morning then I booted in my encrypted Windows partition for my work. I have left my computer downloading 35GB of files and when I restarted in the morning, I booted Windows. When I tried to access Ubuntu, it failed to boot and in low-graphic mode told me that it won't boot because the partition is full. I tried rescue and it reported 0 MB free. I also cannot delete files with sudo rm as all are impossible due to a read-only file system. I can mount it in Windows but there is a "write protection" there, also. Should I try a live USB?

  • How to Access Boot Options 12.04 Live USB

    - by Ryan Kampmeier
    I'm attempting to install 12.04 on my computer but booting from my USB drive results in a blank screen. This has happened since 10.04 and has always been fixed by putting nomodeset in the boot command, but now I can't access the boot options with F6 for some reason. How can I access the boot options? I booted into the live image on a different computer and it worked fine. I'm sure it's because of my Nvidia graphics. When I boot into the live image it shows a small gray box in the lower left corner of the screen and that's it. I can't edit the boot options or do anything else. Thanks in advance.

  • Windows 7: Search indexing is stuck

    - by Ricket
    When I open Indexing Options, it says: 4,317 items indexed Indexing in progress. Search results might not be complete during this time. It's stuck at 4,317 though; no more items have been indexed. Worst of all, SearchIndexer.exe is taking up 100% CPU (well, 50%, but I have a dual core CPU; it's taking up all processing power it can). It is not causing hard drive activity though. I tried clicking "Troubleshoot search and indexing" at the bottom of the Indexing Options window, but it couldn't find any problem. I've also tried the repair registry key that several websites suggest; I change HKLM\SOFTWARE\Microsoft\Windows Search SetupCompletedSuccessfully to 0 and restarted the computer, and it apparently repaired because it flipped back to 1, but the same problem continues to occur. It's reducing the battery life of my laptop and making it really hot so that my fans are running all the time. I've had to disable the Windows Search service. How can I fix this? Do I need to just flat-out reformat my computer? Update: I've tried rebuilding a couple times. There's nothing unusual about the locations I have to index, and I don't have any downloads in progress or anything like that. I don't see any reason why it stopped, and I noticed it much too late to do a system restore. At this point, I'm hoping someone will offer up some secret answer that will fix the problem, thus the bounty. Another update: I tried starting the service again, just to let it try yet again. It seemed okay at first (Indexing Options showed it operating at reduced speed due to user activity, and the number of files was going up). A while later I checked, and the service had stopped. Event viewer revealed some errors like this: Log Name: Application Source: Application Error Date: 2/1/2010 7:34:23 PM Event ID: 1000 Task Category: (100) Level: Error Keywords: Classic User: N/A Computer: ricky-win7 Description: Faulting application name: SearchIndexer.exe, version: 7.0.7600.16385, time stamp: 0x4a5bcdd0 Faulting module name: NLSData0007.dll, version: 6.1.7600.16385, time stamp: 0x4a5bda88 Exception code: 0xc0000005 Fault offset: 0x002141ba Faulting process id: 0x13a0 Faulting application start time: 0x01caa39f2a70ec02 Faulting application path: C:\Windows\system32\SearchIndexer.exe Faulting module path: C:\Windows\System32\NLSData0007.dll Report Id: b4f7a7ae-0f92-11df-87fc-e5d65d8794c2 Event Xml: <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Application Error" /> <EventID Qualifiers="0">1000</EventID> <Level>2</Level> <Task>100</Task> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2010-02-02T00:34:23.000000000Z" /> <EventRecordID>10689</EventRecordID> <Channel>Application</Channel> <Computer>ricky-win7</Computer> <Security /> </System> <EventData> <Data>SearchIndexer.exe</Data> <Data>7.0.7600.16385</Data> <Data>4a5bcdd0</Data> <Data>NLSData0007.dll</Data> <Data>6.1.7600.16385</Data> <Data>4a5bda88</Data> <Data>c0000005</Data> <Data>002141ba</Data> <Data>13a0</Data> <Data>01caa39f2a70ec02</Data> <Data>C:\Windows\system32\SearchIndexer.exe</Data> <Data>C:\Windows\System32\NLSData0007.dll</Data> <Data>b4f7a7ae-0f92-11df-87fc-e5d65d8794c2</Data> </EventData> </Event> If you are having the same error and arrived here from a Google search, please comment or add an answer detailing your progress on this, if any...

  • Monitor displays "No VGA signal" "Check DVI cable" after installing motherboard drivers

    - by user1604220
    I bought computer with all of the needed parts, got everything sorted out, installed windows 7 but my CD-ROM doesn't fit my motherboard. So I had to download the driver manually and install it using USB disc. My motherboard: ECS elitegroup H61H2-M2, I downloaded it's drivers, installed the BIOS map or something, and then the computer forced a reboot after it was complete, after the reboot my monitor just stopped working and displayed No VGA signal, No DVI cable I think I've just installed the wrong driver, well but how can I sort it out? This is the driver I installed. On the book, it tells me to install the drivers, without the driver it won't see the Internet connection cable. I'm 100% sure there is nothing wrong with the monitor or it's cables. it stopped working exactly after the reboot after the installation.

  • Wubi downloaded and installed 64bit 12.10 on my 32bit netbook

    - by Troy
    I downloaded the Wubi installer on my atom N450 netbook. When I started up Ubuntu I got an error that read failed to change the mode of /ect/passwd- to 0600. Then while it booted it froze and several strange characters filled the screen. Finally it loaded it ran pretty slow, and I could connect to my router, but not to the internet. Ping 8.8.8.8 showed no server found. So I checked the about computer and it said I was running the 64 bit installation. Now I know that my computer has a low power 32 bit chip and even the Ubuntu iso download suggested a 32 bit installation. So I went to double check and see if I just missed the option for a 32 bit Wubi install and I did not. There was no option. Is there any way to download a 32 bit version of 12.10 through the Wubi?

  • determine if udp socket can be accessed via external client

    - by JohnMerlino
    I don't have access to company firewall server. but supposedly the port 1720 is open on my one ubuntu server. So I want to test it with netcat: sudo nc -ul 1720 The port is listening on the machine ITSELF: sudo netstat -tulpn | grep nc udp 0 0 0.0.0.0:1720 0.0.0.0:* 29477/nc The port is open and in use on the machine ITSELF: lsof -i -n -P | grep 1720 gateway 980 myuser 8u IPv4 187284576 0t0 UDP *:1720 Checked the firewall on current server: sudo ufw allow 1720/udp Skipping adding existing rule Skipping adding existing rule (v6) sudo ufw status verbose | grep 1720 1720/udp ALLOW IN Anywhere 1720/udp ALLOW IN Anywhere (v6) But I try echoing data to it from another computer (I replaced the x's with the real integers): echo "Some data to send" | nc xx.xxx.xx.xxx 1720 But it didn't write anything.

  • hp XW8000 work station power supply

    - by user281745
    My power supply went up in the XW8000 and I bought a new corsair cx500. I installed it but when I hook it up and I turn the computer on I get a beeping noise from the computer. I looked at the old power supply and the new power supply. The only difference is that the new power supply has 500 watts and the old one is 450 watts and the old PSU has a brown wire and the new power supply has 2 orange wires at the end. I found out that it is a sense wire that is in a different location so I was wondering how do I fix this problem.

  • Why do I get a blank screen when starting Wubi?

    - by August Guillaume
    I used Wubi to download 12.04 on a new partition. When restarting, the computer (Levono windows 7 -64) froze with no signal on my screen. Turning the computer on and off I received the option to sign in on windows or ubuntu. Windows worked well, but Ubuntu seems to bomb again as before. I can look at the new partition where some Ubuntu files exist via Windows explorer. What am I to do? Is 12.04 compatible with windows 7?

  • Crontab opens as blank page, cannot save

    - by Sarah
    I am really not familiar with linux, and only started using it recently, so be patient with me. I am trying to control a camera on regular intervals through a script that is called upon in the crontab. When I start up the computer, I can open crontab, edit and save, and everything is executed correctly. However, I can never open crontab a second time, unless I restart the computer first. If I type crontab -e, I get a blank page, located in the /tmp directory. I can enter my commands in there, but cannot save it. I don't know if this is relevant, but when I try sudo crontab -e, I get something like "no cron installed for root". Any help is really appreciated! Sarah

  • Uncontrolled Fan and Crash

    - by RobotbeatsHuman
    I don't have sensors to properly run lm-sensors. The computer will turn on but shortly there after all the fans in it will speed way up. It stays like this for a few minutes and then the computer shuts off. Tried resetting the BIO. Went to try installing a BIOs update but it wont stay on long enough for me to try that or to do a clean install. Could this be the motherboard dying? It's mainly the CPU fan that ends up going max. after a few minutes. I checked the PSU and It's a Dell Inspiron 580. If you need more system specs just le me know.

  • Issues with Dz77BH-55K Motherboard and i7 processor on 12.04

    - by Naveed
    I just built a computer with Intel's DZ77BH-55K motherboard with i7-3770 processor. On 12.04, 11.10, and 11.04 and Linux Mint 12, the computer has been really laggy. The graphics aren't working (choppy effects, bad resolution) and the keyboard and mouse inputs are even laggy and unreliable (skips keystrokes). I'm not sure what the problem is or what I can do to fix it. I tried sudo apt-get install mesa-utils but nothing changed. I've also messed around in the BIOS but no luck there either. Any ideas? Could it possibly be a hardware issue?
