    Re: Ubuntu, xfce, lxde and system optimization

    I had the HP 6000 myself until it died. Long story.

    Should be running fine now with all flavours.

    I was doing something the other day and got a similar message. This system has Lubuntu, Lubuntu Netbook, GNOME/OpenBox and Ubuntu. After the results, I will try it on my primary linux machine, the Acer D250.

    Another option I thought of was to do a complete re-install from the disk. So far I have been installing from the UBUNTU 10.04 LTS Desktop Edition cd that came with "The Official Ubuntu Book." Will I have the option for a minimal ubuntu install from that disk?

    More importantly, as mentioned in the code above, why am I "unable to lock?"

    seppalta, i'm gonna put that link on the backburner. A little technical for me, but I think I understand most of what's going on. Essentially, endorsing Xubuntu but installing LXDE, right? My primary goal is to clean out any extra packages/desktop environments. Well, keeping Ubuntu/Unity on my netbook as well as LXDE, but then running a LXDE/*buntu system on my Hp laptop.
    It looks like you have another program running, that is also managing installation and removal of program packages, for example Synaptic or Software Center. Close that program and try again!

    Press the TAB key to move the cursor (active field) to the OK field, and press Enter to confirm.

    It's time to trash your 10.04 disk, as support ends in 2 months.

    Here are easy instructions to perform a "minimal Ubuntu install" if that's your thing: http://www.psychocats.net/ubuntu/minimal

    [QUOTE=snowpine;12515943]Here are instructions to remove Xubuntu and install "pure" Lubuntu: http://www.psychocats.net/ubuntu/purelubuntu

    So, I copy/pasted the terminal command for removing Xubuntu for 12.04. After lines of code, here is the response:

    Code:
    Some packages could not be installed. This may mean that you have
    requested an impossible situation or if you are using the unstable
    distribution that some required packages have not yet been created
    or been moved out of Incoming.
    The following information may help to resolve the situation:
    
    The following packages have unmet dependencies:
     libxine1-ffmpeg : Depends: libmad0 (>= 0.15.1b-3) but it is not going to be installed
     libxine1-misc-plugins : Depends: libgraphicsmagick3 (>= 1.3.5) but it is not going to be installed
                             Depends: libmng1 (>= 1.0.10) but it is not going to be installed
    E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

    I should clarify at this point that this pertains to my Acer netbook running 12.04 (I know I've been jumping around a bit):

    Okay, before I proceed, this was returned:

    Code:
    The following packages were automatically installed and are no longer required:
      gir1.2-totem-1.0 libunity6 linux-headers-3.2.0-36 linux-headers-3.2.0-37
      linux-headers-3.2.0-37-generic libtotem0 libdee-1.0-1 linux-headers-3.2.0-36-generic
      gir1.2-totem-plparser-1.0
    Use 'apt-get autoremove' to remove them.
    0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
    I assume this command would be 'sudo apt-get autoremove' followed by the lines above. What I am concerned about is 'libunity6.' I just want to make sure that that is an aspect of Xubuntu and not my standard Ubuntu shell. I do like Unity and standard Ubuntu on my netbook, but I would like to try out LXDE with it as well. I simply want to purge as much of Xubuntu/XFCE as I can.

    Re: Ubuntu, xfce, lxde and system optimization

    Code:
    sudo apt-get autoremove
    is a complete command, and it will remove the above mentioned packages. If you want to reinstall Unity, no problem. You can do that from a text screen according to the tips in the 'psychocats' link, if you have removed or broken every graphical desktop environment.

    If you don't want to remove all of them, remove those you want to remove with
    Code:
    sudo apt-get remove package1 package2 ...
    Learn more about apt-get in
    Code:
    man apt-get

    Re: Ubuntu, xfce, lxde and system optimization

    Haha, okay! I think I've indeed broken every desktop environment successfully. Here are some of the issues that I am having:

    Unity/Gnome are still showing up in my login manager, but definitely do not work

    LXDE has been installed, but the system is acting strange and unstable.

    Xfce/Xubuntu has not been removed/purged, but I can and sometime feel I need to login to an xfce session, but it is also unstable.

    Trying to use gparted to create a new ext4 partition, but cannot strictly copy my Home folder to because I am not allowed permissions (and I have yet to backup anything linux)

    When I log into ttyX shell or whatever the correct terminology is, a wireless bug keeps printing "no mac address," but someone informed me that is a harmless bug. I just know that it wasn't happening until I did whatever I did.

    The netbook is dual booting this broken 12.04 and windows 7 starter. I used pendrive linux usb iso program on the windows side previously to create different flash drive 'live cds' and it is not allowing me to anymore. The system is again telling me that I don't have permission to even format the 8g flash drive. I'm not even sure if these problems are related.

    And....that's all so far. I have a command that I'm going to try for backing up my home folder, but then I think the best idea is a clean reinstall, maybe just go straight to the most recent .iso of Lubuntu and be done with it. However, I need to create a bootable flash drive, and can't seem to do it anymore. I've dug myself into a hole for sure! This is fun! (but also a little inconvenient). Maybe I should try to create the usb drive from linux, but I'm worried if my system is stable enough to do so (and I need to do a little research to see how best to proceed). Hmmm....

    Yes, a clean install is the best option, just backup your important data and create a separate home partition this time.

    However, I need to create a bootable flash drive, and can't seem to do it anymore.
    With your pendrive mounted type:
    Code:
    df -h
    This command will show the partitions you have and how much space is used/free in each, it shouldn't be difficult to identify your pendrive.
    Let's say that your pendrive is in /dev/sdb then this command would be enough.
    Code:
    sudo dd if=/path/to/your/lubuntu.iso of=/dev/sdb && sudo sync
    Replace the paths for input file and output file. Be very careful because if /dev/sdb is not your pendrive you could completely erase another hard drive! Also notice that you type the address of the hard drive, not the partition (/dev/sdb not /dev/sdb1)

    Hope that makes sense
