  • How to login after modifying ~/.profile wrongly

    - by Jasper Loy
    I did something very silly a few weeks ago. I wanted to add a path so that the OS could find some manually installed executable. Instead of typing 'PATH=xxx:$PATH;export PATH' at the end of the ~/.profile file where xxx is the directory in which the executable lies, I accidentally typed 'PATH=xxx;export PATH'. After I logged out I was unable to login anymore as I probably messed up the whole PATH variable and reinstalled the whole thing. My question is: is there a way of rectifying the situation if I happen to add the path wrongly (hopefully not!) in future?

  • USB Mouse stutters periodically

    - by greggory.hz
    I'm using an HP dv6000 (not sure of exact model) with a pretty basic Logitech wireless laptop mouse. From time to time, the USB mouse will be very stuttery and less responsive. Not all clicks register and the motion is not smooth. It seems like it's related to the notify-osd coming up when I get an IM or Email or whatever else, but it happens other times as well. It's not the whole computer becoming less responsive, because if I use the touch pad during one of these fits, it works perfectly smooth. I've replaced the batteries in the mouse and have tried different USB ports with better line of sight, etc. I can't figure out what's going on. Any thoughts?

  • Ubuntu won't appear on laptop startup

    - by Jade
    I've recently installed Ubuntu along with Windows Vista. So normally when the laptop is starting up it shows two options whether I want to log on Windows or Ubuntu. One day I shut down the laptop and I open it the next and it just logs onto Windows automatically without giving me the option to choose. I go to check if Ubuntu was un-installed or something, but it was still there and everything, but I can't open it. I don't know if there's any additional info I should add because I'm not very good with computers, and I don't want to re-install it because I have my stuff on it so I'd lose it, and I'm having trouble backing it up. Any suggestions?

  • CPU spikes to 100% when trying to watch video

    - by mark
    I just installed Ubuntu 12.04 and now CPU spikes to 100% when trying to watch a video. I don't want to hear that this is a problem with Flash or whatever... Playing video on my machine with Ubuntu 11 was just fine. In fact I have another machine still with Ubuntu 11 and it continues to play video just fine. Now I'm stuck with this 12.04 version and want to know how to downgrade back to version 11 as that version isn't buggy. (hence a downgrade).

  • No access to Samba shares

    - by koanhead
    I have three shared folders in my local home directory- that is to say, on my Ubuntu desktop's /home/me/. All were set up using "Sharing Options" in Nautilus' right-click menu. The standard "Music" and "Videos" folders are configured identically: the "Guest Access" box is checked, but the "Allow others to create and delete" is not. The third folder, called "shared", is configured to not allow Guest access but to allow others to modify files. I have not altered /etc/samba/smb.conf by hand, I have only used Sharing Options to create and modify these so-called "shares". My roommates have two Windows 7 computers and one Ubuntu Netbook Remix netbook. I have the aforementioned desktop machine and laptop running 10.04. None of these machines can access any of the shares. Attempts to access the Guest shares result in the message \\machine\directory is not accessible. The network name could not be found. This is the error message generated by a VM running Windows 2000. The other Windows machines generate a similar error. The Ubuntu laptop gives the error Unable to mount location: Failed to mount Windows share. Hurrah, once again, for informative error messages. That really helps a lot. When attempting to browse the folder called "shared" from the laptop, I'm confronted with a password dialog. This behavior is the same will all machines I've tried in the situation. On entering my username and password for the account to which the shares belong, the password dialog briefly disappears and is replaced with an identical dialog. No error message, useful or not, appears. When attempting to browse this folder with the VM, the outcome is the same except that the password dialog helpfully states "incorrect username or password". My assumption is that the username and password in question is that of the user which owns the shares. I have tried all other username and password combinations available in this context and the outcome is the same. I would like to be able to share files. Sharing them with Windows machines is a nice feature, or would be if it was available. Really I consider sharing files between two machines with the same version of the same operating system kind of a minimum condition for network usability. Samba last functioned reliably for me more than ten years ago. I have attempted to use it on and off since then with only intermittent success. Oh, and "Personal File Sharing" from the Preferences menu does not result in an entry in Places → Network → my-server. In fact, the old entry "MY-SERVER" goes away and is replaced by "koanhead's public files on my-server", which when I attempt to open it from the laptop gives a "DBus.Error.NoReply: Message did not receive a reply." I know I come here and gripe about Ubuntu a lot, but on the other hand I spend literally hours every day trying to fix things in Ubuntu. It's a good system which aspires to greatness, which is why things like this either Need to work; or Be adequately documented. Ideally both would be the case. Anyway, rant over. Hopefully someone will have some insight on this issue. Thanks all who bother to read this wall o'text for your time.

  • Jumping Login Box after Lighdm Multiple Monitor workaround

    - by Tom Gamon
    So I used this workaround to sort my resolution at the login screen when using multiple monitors with Lightdm. #!/bin/bash XCOM0=`xrandr -q | grep 'VGA1 connected'` XCOM1=`xrandr --output LVDS1 --primary --auto --output VGA1 --auto --right-of LVDS1` XCOM2=`xrandr --output LVDS1 --primary --auto` # if the external monitor is connected, then we tell XRANDR to set up an extended desktop if [ -n "$XCOM0" ] || [ ! "$XCOM0" = "" ]; then echo $XCOM1 # if the external monitor is disconnected, then we tell XRANDR to output only to the laptop screen else echo $XCOM2 fi exit 0; Found Here: How to force Multiple Monitors correct resolutions for LightDM? It works great. However, now when I am on my login screen, the login box seems to jump to between the two displays. Any advice as to how I could make it stay on one display? Thanks

  • Issue with increasing the root partition from the swap

    - by user211761
    I have an issue with increase the size of my root partition. I have ElementaryOS Luna, and while installing it asked me how much space I want to use. I choosed 15 GB for it, because I want to use this as an alternative system. The issue is that after the installation was complete, I found out that my root partition is only 7 GB big, and SWAP is 8 GB which is useless cuz I have 8 GB of RAM. Now I want to shrink the swap and increase the size of my root partition, so I booted the LiveCD and used GParted. I shrinked the swap without any problems, but now I cant add that free space to any partition. I also turned Swap off. I would add a picture, but I need at least 10 reputation to post images ( Stupid ) Its also worth mentioning that in Gparted its showing my partition in a different way. I would post an image BUT I CANT, so I need to write it down. Its something like this [Pointing arrow down] /dev/sda4 Extended /dev/sda5 ntfs /dev/sda6 ext4 (Which is my main partition) /dev/sda7 linux-swap unallocated Picture:

  • Got problem with installation. "No root file system is defined."

    - by user92322
    I'm very new with Ubuntu and generally with linux. I saw ubuntu and it seems like this OS is really good and stable, and so I decided to install it alongside my windows 7 OS. I have a few problems with the installation. Here is what I did: I downloaded the 64bit version from Ubuntu official website, and burned it on a dvd. I set the boot sequence to first load from my CD-Rom. Ubuntu installation started, and I chose "Install Ubuntu" in the menu. (where there is also a "Try Ubuntu" option) I clicked forward until I got into the installation type screen As you can see, the installation wont show my actual details about my hard drive! I have 1 hard drive with 750 GB - 80 GB - My main drive with windows 7 OS 600GB - All of my stuff 20GB Free space that I saved for Ubuntu But the installation wont show that!

  • I'd like my window switcher to be per-monitor. How do I do that?

    - by Erigami
    I have a multi-monitor setup with nVidia drivers, running Unity/Compiz on 12.10. I'd like to treat each monitor separately, so I can switch desktops on one without affecting the other and run a window switcher that only switches between windows on the current monitor. How do I do that? None of the switchers listed in ccsm seem to limit themselves to the currently focused monitor, ditto for desktop switchers.

  • Can I set up a hostname alias that is only active in a specific network?

    - by denisw
    I have a small ARM box running ownCloud in my house, and a domain bound to my DSL router with Dynamic DNS. This works well as I can configure the ownCloud client to use the domain name, which works both in the house and when I'm on the road. However, at home I would like to let my laptop and my server talk to each other directly on the local network, rather than as if they were talking over the Internet (including DNS resolution for my domain name, routing all traffic through the DSL machinery etc.). I know that I can set a hostname alias for my domain in /etc/hosts - the problem is that I want this alias to only be active when I'm in the home network, while in all other cases DNS resolution should be used as normal. Is this possible?

  • Renaming hundreds of files at once for proper sorting

    I have a ton of files, all named stuff like 1.jpg, 2.jpg, 3.jpg, and so on up to 1439.jpg. However, I have a problem with one of my projects and alphabetizing. It will usually go in the order 1.jpg, 10.jpg, 11.jpg and so on. What I need is some way (or a script) to name the files so they are in the format such as 00001.jpg all the way up to 01439.jpg. How would I be able to do this quickly and efficiently?

  • Can't read CDs, can't create USB... how do I install Ubuntu?

    - by user68080
    Hello everyone and thank you in advance for your time. I have troubles with the latest Ubuntu distribution: since I upgraded to 12.04 Ubuntu has started having troubles (internal errors, packages that crash repeatedly, I can't install new packages, Ubuntu Software Center crashes, Java apps that worked stopped working and display weird mistakes, files were corrupted... a mess). I ultimately decided to format everything and install 12.04 from scratch. I made a backup and everything, but now I have troubles installing ubuntu 12.04. Specifically, a CD I burned with Brasero that works on another PC is not read by my laptop (not at boot phase, nor inside Ubuntu), and when I try to create a USB with Ubuntu (following the instructions I found on the ubuntu site) Startup Disk Creator stops at 22% saying that "the codes do not match". Any idea on what to do next? No, I can't buy a new PC.

  • Can't install AMD drivers and Blinking problem

    - by demonscream
    I just installed Ubuntu 12.04 LTS with WUBI, everything is going fine and ubuntu is awesome but i have a little problem. When i open my Sony VAIO model E laptop, i have 2 choices (which is normal) but when i select Ubuntu 1/2 of the time it will just give a rapidly blinkin color background and can only be corrected if i reboot the computer and select ubuntu again. I think this has something to do with the fact i can't get any driver update for my computer from AMD, according to their website, VAIO computers aren't supported. I have a AMD RADEON HD 7650M graphic card which is not detected in ubuntu. When i try to install the drivers using the drivers application it gives a "can't install" error. What should i do?

  • Ubuntu 12.10 not working on UX32VD after update to beta 1 [closed]

    - by bquast
    Possible Duplicate: There's an issue with an Alpha/Beta Release of Ubuntu, what should I do? In my previous question I described my problem with starting / returning from suspend using Ubuntu on the Asus UX32VD (Zenbook). This problem could be solved by using Ubuntu 12.10 (alpha), however since the upgrade to beta 1 the old problem of starting / returning from suspend has returned. I found that starting in recovery does work, but this of course does not solve the problem. Any thoughts?

  • How to remove Ubuntu from dual boot system with Windows 7?

    - by user71307
    I wish to remove Ubuntu and I'm not quite sure how. I know it has something to do with partitions. I have 3 partitions. 1. OS [683 GB] 2. Recovery [14 GB] 3. Ubuntu 12.04 LTS (E:) I know it says Ubuntu but when I installed Ubuntu I think I put 14 gigabytes for it so I think its the recovery one but I'm not sure. I could have sworn I put more than 700 megabytes for it. I have googled this and I can't seem to find an answer. Any help would be nice.

  • How to remove Ubuntu and put Windows back on?

    - by Josev King
    I installed Ubuntu 12.04, as a dual boot on my windows Vista laptop, and the next thing I know, I get black screen with error: unknown filesystem. grub rescue> I have tried reinstalling Windows, reinstalling Ubuntu, booting from Ubuntu disk, and managed to actually get into the OS, but there is nothing I can find of uninstalling Ubuntu, and deleting the partition it created. I know nothing at all about Linux, and I desperately need to get my laptop back up and running.

  • Incomplete Ubuntu 12.04 install dual-boot XP

    - by Mike
    This weekend has been the 1st time I've tried to install Ubuntu. On the initial install, (I am using a USB) the installation went all the way through and asked to restart when completed. I was not able to get grub to boot and kept going through Windows. After some research I found some articles on updating/reinstalling grub, so I followed those. I finally got grub to load after a day but there was no Windows option only the Ubuntu 12.04 which when I selected it only gave me a fatal error 17. I booted from the USB again and deleted the partitions and installed again. This time I got an error 15. I then booted through XP and downloaded the WUBI.exe and uninstalled Ubuntu and reinstalled again. The installation went to the very end and then gave an error message (which I don't remember exactly what it said) something along the lines of checking my logs on my C drive. I then uninstalled Ubuntu and removed the wubi.exe file and wiped my USB and did the download to the USB again. Booted through USB and ran the install process again. It again went through the install process but after creating username and password and hitting continue, the installation dialogue box disappears and the mouse spinning wheel is displayed, but I do not receive the prompt to restart. I can still access the side menu for Ubuntu but the wheel keeps spinning. How do I get Ubuntu to install properly?

  • Unity freezes when laptop screen is closed

    - by Giacky98
    I have an Asus laptop running Ubuntu 12.04. It's configured to do nothing when the laptop screen is closed. But sometimes, when I close the screen and when I reopen it, after I move the mouse to reactivate the screen, my Unity interface is frozen and I can't click on anything. I can move the cursor, and if there's a music playing it keeps playing, but I can't click on anything. I can open a bash shell typing Ctrl+Alt+F2, but there I don't know what to do, I can only login and type sudo reboot to reboot the machine... Is there someone that has the same problem or that knows the solution?

  • Can I invoke a graphical program to run with a hidden window?

    - by Willi Ballenthin
    I have a program that interprets the input from my mouse and provides multitouch gestures. I wrote it using a game engine, which always creates a window when it runs. I'd like to run this program without seeing the window, so this is the point of the questions: Can invoke a graphical program but have the window hidden? By hidden I mean anything that keeps me from encountering the window on my desktop. So I would accept something like, "open on a different, previously non-existant screen."
