• Laptop keyboard and touchpad disabled on startup

  - by JAM

  I use Ubuntu 14.04 LTS on my Toshiba Satellite L775D laptop. 14.04 is the only operating system installed. I am new to Linux and only barely scratching the surface of doing things in terminal. When I boot my laptop keyboard and touchpad are disabled (99.99% of the time) if I do nothing. The only direct effect I can have is to keep pressing the "numlock" key during boot when I notice the "numlock" light goes off. If I do this then I have a 95% chance of the keyboard and touchpad working when I am in the operating system. I am able to use my wireless mouse regardless. I have not seen any messages during boot. Previously I have tried playing with input method settings and utilities as well as language support settings. This same problem exists with the 12.... and 13... versions of ubuntu. With everything I have tried (from looking at other posts/suggestions) it seems I can have only a temporary effect. Please help me find a permanent solution to this problem. thank you.

• backlight doesn't work on acer 5732z tried everything I can find

  - by Dude Random21

  Ok if you can solve my problem you're really really good. I want to run ubuntu 12.04 on my acer aspire 5732z I know (from research) that these computer's have issues with the backlight on ubuntu. So I tried a couple of solutions: The "sudo lightdm restart" method. I get no change at all. The "sudo setpci -s 00:02.0 F4.B=30" method. This so far has been the most effective, I first tried it in the F1 console right away I get the screen back, problem is going back to the desktop it goes back to being black. So I tried it from a terminal window and it works as well but as soon as I unplug my external monitor the screen turns black again and doesn't come back. If I plug the monitor back in the screen stays black and the only thing I see is the mouse pointer. From here I go back into console (which I am able to see) and reboot from there. The "sudo sed -i 's/GRUB_CMDLINE_LINUX=""/GRUB_CMDLINE_LINUX="acpi_osi=Linux"/g' /etc/default/grub" method. This one I got no instant change and after reboot still no change. I'm open to pretty much any suggestions you may have.

• How to ensure nvidia_current module loads during boot

  - by Aras

  I am running Ubuntu 12.10 on an Asus G75V laptop with nvidia gforce GTX 660M. I first run 12.04 on this machine and was able to install nvidia_current drivers from swat ppa: sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current This worked in 12.04 and after rebooting the machine my graphics where working properly. After upgrade to 12.10 however, the machine boots into a low resolution desktop which I can not really interact with. I suspect this is due to the driver not being loaded properly. To fix this, I have to switch to ctrl+alt+F1 session and manually load the nvidia_current module and restart the desktop manager: sudo modprobe nvidia_current sudo service lightdm restart Now everything works fine again. However, I would like not to have to do this every time I reboot the machine. I also dont want to hack an script to do this on load. Basically, if things are setup currectly, the nvidia_current driver which is installed should load. How can I make sure nvidia_current driver module loads properly when system starts?

• 12.04 backlight issue for Acer Aspire 5734z-4725 running on usb flash drive

  - by Shawn

  I have followed the fix found here: Backlight Issue However I can't use the sudo update-grub2 command as it errors with /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). As this laptop's hard drive is shot, I can't install the OS. I have been able to get it to temporarily work with sudo setpci -s 00:02.0 F4.B=00. I'm new to Ubuntu, so if you know how to fix this please provided as much detail to what I would need to do.

• background process outputs to the console

  - by broiyan

  Suppose test.sh is a bash script that is empty or contains only exit 0. When the script is backgrounded, what is the significance of the 1 and 16320 printed to the console? b@sam:~/Documents/bashscripts$ ./test.sh & [1] 16320 b@sam:~/Documents/bashscripts$ [1]+ Done ./test.sh b@sam:~/Documents/bashscripts$ Then if user hits ENTER at the command prompt, as illustrated above, another line appears and it shows this [1]+ Done ./test.sh What is the significance of the 1 digit and the + symbol?

• How to edit files in a terminal with vim?

  - by andrew.46

  It is not always possible to edit and create files in a terminal and I would like to get the answers to the basics of manipulating files in a terminal using vim under Ubuntu Linux. Specific questions I have are: How can I open text files for editing? How can I save the file? How can I save the file with a different name? How can I leave the file without saving the changes? What settings are best in my configuration file and where is this file? How do I set the colors for vim? How do I show line numbers in vim and can this be toggled? A lot of questions here but I believe these questions and their answers should cover basic vim usage...

• Acer Aspire 5542G overheating with ubuntu/kubuntu 12.04

  - by james

  I have an Acer Aspire 5542G laptop purchased couple of years ago. All these days, i used windows 7 on it . Then I tried ubuntu 12.04 . Everything was fine except the overheating issue. I updated ubuntu with all security fixes and available updates but nothing solved the problem. With idle use like internet browsing, the cpu fan speeds up a lot and i can feel very hot air coming from the vent (comparable to playing serious 3d game in windows). But it will not go to a point of freeze and shutdown. But as long as im using it, with no intensive tasks at all, the laptop stays too hot. This wasn't the case with windows7. In windows 7 the fan will not rotate at all with normal use. I heard there was manufacturing defect with some acer laptops, but i think it wasn't the case with my laptop since windows7 runs perfectly. I updated the bios to latest version. I cleaned dust in the vents. I tried kubuntu 12.04 up-to-date. Nothing solved the issue. My laptop specs are: CPU : AMD turion2 x2 M500 @ 2.2GHz GPU : AMD Mobility Radeon HD4570 3GB RAM and 320GB hard disk.

• Dash home button in unity5 of new ubuntu 12.04lts

  - by Aps18

  If I click on the dash home icon nothings come up. It's as if it's not responding, but just above the dash home icon, I can see close, minimize and restore buttons. I have tried all the links present in this forum, so please don't suggest these: sudo apt-get install --reinstall unity unity --reset pkill -f unity-applications-daemon None of those worked. I am facing this problem after upgrading to 12.04 LTS.

• Can't set proper resolution with a Geforce 520

  - by D0X

  I installed the 12.04 LTS but cannot get my two monitors working. The latest nvidia-current drivers installed, but i just cant set proper resolution. My card is a geforce 520 1 DVI 1 VGA. With the nvidia drivers installed i can set the DVI monitor to 1600x1200 but the VGA no further than 1360x768 (with nvidia-settings). Without the nvidia driver (using the nouveau) it doesn't work either. This same issue i had with 11.10 and i had high hopes for 12.04.

• Copying VBoxAdditions to usr/share/virtualbox folder

  - by Joe

  Since for some reason VBox does not find the Additions on the internet, I was trying to install them in the Ubuntu directory Vbox is looking for them - which is: usr/share/virtualbox but I am denied permission to do so. Any way around it? I am relatively new to ubuntu (know how to use the GUI, but still learning how to talk to the machine proper, so many things will be new to me; used to be power user/analyst for MS Windows, 98-Vista, so not a PC newbie, but still I'd say Linux newbie). Any suggestion is more than welcome! Thanks Joe

• Connecting / disconnecting DisplayPort causes crash

  - by iGadget

  I wanted to file a bug about this using ubuntu-bug xserver-xorg-video-intel, but the system prompted my to try posting here first. So here goes :-) While the situation in Ubuntu 11.10 was still somewhat workable (see UI freezes when disconnecting DisplayPort), in 12.04 (using Unity 3D) it has gotten worse. The weird part is that during the 12.04 beta's, the situation was actually improving! I was able to successfully connect and disconnect a DisplayPort monitor without the system breaking down on me. But now with 12.04 final (with all updates), it's just plain terrible. When I now connect an external monitor using the DisplayPort connector on my HP ProBook 6550b, it only works sometimes. Most times (but not always!) the screen just goes blank and the system seems to crash (not even CTRL+ALT+F1 works anymore). Only a hard shutdown by keeping the power button pressed for several seconds and then a restart gets me out of this. I suspect the chances of the system crashing become higher as the system's uptime increases, especially when there have been one or more suspend-resume cycles (although I have also experienced this bug once from a cold boot). Disconnecting is roughly the same as with 11.10 (see issue mentioned above), with the difference that if I resume from suspend, I no longer have to do a CTRL+ALT+F1, ALT+F7 cycle to get my screen back. So what more can I try? Or should I just go ahead and file the bug anyway?

• How do I fix a terrible system error on ubuntu 12.04

  - by Anonymous

  I don't know what happened, but one day my computer had some sort of a system error and could no longer update itself. The software center will not open, it will begin to initialize and then a message pops up saying theres a system error and needs to shut down the software center. Then another box pops up after I go to report it saying it was unable to identify source or package name. I also can't extract a zipped folder to anything, or reinstall Ubuntu from a USB boot drive anymore, it keeps telling me my my computer isn't compatible when I know for a fact it is, because thats how I got Ubuntu on here in the first place. the only thing I know about this error is that a message popped up after I went to check for updates saying to report the problem and include this message in the report: 'E:malformed line 56 in source list /etc/apt/sources.list (dist parse)' it also called it a bug. I just want to know how to either get rid of the bug completely or find some way to be able to reinstall Ubuntu again. I know it's not a lot of information, but It's all I can give. Sorry.

• Special keyboard keys?

  - by Hailwood

  I have a new laptop, It has the icon for toggling the touchpad on fn+f1 so I would like to assign this shortcut, I have a working script, and I can assign the script to any other combination, but it appears that ubuntu does not pick up the fn+f1 combination? how can I correct this? The other one is, My laptop has three extra buttons, Assist, Web, and Vaio. These map to Help, Homepage, and nothing respectively. the Web button is working perfectly. The assist button if I am setting up a keyboard shortcut for something it binds fine, but then pressing it does nothing? The Vaio button seems to not be listened to much like the combination I posted above. How can i correct the assist and Vaio buttons?

• Cannot see user desktop when I log in

  - by Jesi

  I am very new to Ubuntu. I recently got a new laptop running Windows 7. I am using Virtual Box and just installed the Ubuntu 12.10 ISO as a new Virtual Machine within Virtual Box. Everything seemed to install just fine and I even added the Guest Additions under Devices. The problem is that I cannot see the menus and my login information. The virtual machine says it is running; however, I do not have the Applications, Places, System, etc. tray to select from. Is there something I am supposed to do after logging in to get this? I entered my password and everything seemed fine, I just don't have those drop-down menus available... Thank You! Jesi

• Problems with NAT Adapater since upgrade to Ubuntu 12.10

  - by jjesse

  I was running Ubuntu 12.04 w/ VirtualBox installed. I was using the NAT interface to connect to everything. Basically running VBOX for testing some things and a Windows VM for Netflix.. Was back to working in my VMs today and noticed that I was unable to connect to the internet. In the VM settings I'm using the NAT adapter, however I noticed there is no NAT adapter in the Network Settings under Preferences in VBOX. Not quite sure what happened but wonder what is going on? I noticed there are some posts about changes DNSMASQ and configuring a bridge mode, but this worked out of the box under 12.04 and since the upgrade this no longers work. Need some help please

• unreachable subnet in one direction

  - by Carl Michaud

  I'm unable to route traffic to a subnet in my home. Here's my topology: INET <- Router A <- Router B <- WIFI AP where: Router A - ARRIS TG862G/CT (from comcast) - WAN DHCP, LAN 10.0.0.99 Router B - Linksys WRT400N with DD-WRT - WAN 10.0.0.12 , LAN 10.0.1.1 I was able to use DD-WRT to configure a static route for the 10.0.1.x network back to the 10.0.0.x network. But I'm not sure if i can do the reverse on the ARRIS router and was looking for suggestions on how to fix that. I've set things up this wasy because I am using OpenDNS to mange internet content for my kids and of course I wasn't able to configure DNS to my liking on Router A either. So at present I'm using Router A on 10.0.0.x to provide a private unfiltered WIFI AP (no ssid broadcast) that I use for netflix only and then I use router B to provide a filtered WIFI AP for the rest of my WIFI devices on 10.0.1.x. However I would like to be able to connect to my 10.0.1.x devices from the internet via dynamic dns; but I can't see anything behind router B this way. Thoughts?

• Dolphin search bar missing. How can i get it back?

  A while ago, my search bar went missing in dolphin. If the search toolbar is checked for view/unhide, nothing shows up. I noticed if i check and uncheck the button to hide/unhide it, a small, thin content-less bar slightly pushes the rest of the toolbar up. i tried reconfiguring with dpkg, purging and reinstalling, etc. i left it alone as i thought it would be fixed in an update, but today i upgraded daolphin and it's still gone. any thoughts?

• Ubuntu 12.04 Hp G72 Problem Installing proprietary wireless driver

  - by user69402

  I have a fresh Ubuntu 12.04 installed on HP G72 machine. In order for my wireless to work I need the proprietary driver installed - Broadcom STA wireless driver. Trying to install it from the System Settings gives me the error: "Sorry, installation of this driver failed. Please have a look at the log file for details: /var/log/jockey.log". So far I suspect the error to be caused by the bad "bcmwl-kernel-source" installation. What i tried: 1. remove "bcmwl-kernel-source" 2. install "bcmwl-kernel-source" installation through the terminal ends with "error code (1)". I would greatly appreciate any help Here is everything that the terminal returns: Reading package lists... Done Building dependency tree Reading state information...

• Trouble installing downloaded program

  - by Hamlette

  I purchased and downloaded Celtx and I'm having trouble installing it (in Ubuntu 13.04). I'm a Linux newbie (literally had it for four days) so please be kind and don't assume much experience with the command line, I'm still learning. The folder with all related files/packages etc. is under "Downloads" and I have tried several commands to try and install but I'm just not doing it right and would appreciate help with exactly what command(s) to use. Sudo apt-get install celtx did not work. I'm assuming I'm missing a step somewhere.

• How to copy a DVD [closed]

  - by ring0

  I was offered a couple of DVDs from abroad that cannot be played on my player due to region filtering. So I tried k9copy to copy the DVD (it removes the region automatically). But for some reasons the copy does not work well (followed the instructions from here but the generated ISO file does not work / not even in media player - additionally there are many bugs in k9copy 2.3.5 (latest from Ubuntu) showing that it is not a reliable software, at least not on Gnome...). My question is simple: how to copy a DVD on Ubuntu, the copy/ISO being as close to the original, but without the region code.

• How to set up an ethernet and wireless network using /etc/network/interfaces?

  - by den-javamaniac

  Hi. Currently I have ethernet and wireless networks configured through a network manager (further NM) but it seems to be a bit buggy (I need a different MAC for ether which is never applied if using NM), so I would like to move all the network configs to interfaces file. I know (or can google for) configuration code, but I'm not sure how NM works and it looks like it overrides interface config. Please advice, how I can handle this issue. NOTE: I also would like to be able to locate and connect to various wireless networks but not sure how to do it.
