    Many newbie Q's. NVIDIA Display Drivers, Dash, Unity bugs, general use

    Hi All !
    I'm a new Ubuntu user , and am liking it.


    I am running Ubuntu Studio 18.04
    I have a few newbie Q's (or lots?).
    Maybe I should put them in individual forum posts?


    Thanks in advance for any and all replies.
    ======================================
    -- Reading through the manual, I see that there is a function called "Dash".
    I cannot find a way to use this !!
    It seems like a similar interface and function to mac's "spotlight" , a function which I love.


    Dash seems to be absent from my OS.
    The unity desktop, which dash it is a part of, also seems to be absent.
    I seem to have the XFCE desktop and panel, which I like very much, and probably don't need unity,
    although it might be nice to be able to install unity to see if I like it, if I can uninstall it?


    That said, I really just want the Dash feature only.
    I probably don't need the launcher or anything else about unity , per se.
    ======================================

    I have attempted the following in terminal in an attempt to get unity, and bugged up my system.
    https://itsfoss.com/how-to-fix-no-un...-10-quick-tip/

    sudo apt-get update
    sudo apt-get install --reinstall ubuntu-desktop
    sudo apt-get install unity
    sudo shutdown -r now


    This seems to have had MANY bad effects, and has made my system buggy.


    I have attempted to both uninstall and purge :
    sudo apt-get purge ubuntu-desktop



    no luck !
    I now get error messages when I restart ubuntu, relating to my display. The following :


    DisplayCAL Profile Loader 3.5
    (my monitor model) (resolution x resolution) : Display profile couldn't be loaded.

    Also failed unity processes seem to continue running, such as during login time, the screen is different to how it was before.


    How can I undo what I have done?


    This even seems to have affected my chromium extensions somehow.
    I don't see how, but suddenly after doing this, various of my chromium extensions are failing.
    Maybe just coincidence.
    The two things seemed to coincide exactly together.
    ======================================
    How to install the proprietary NVIDIA drivers ?
    I've got the .run file from the Nvidia website :


    But when I run it , I get a terminal window with following message.
    ERROR: You appear to be running an X server; please exit X before installing. For further details, please see
    the section INSTALLING THE NVIDIA DRIVER in the README available on the Linux driver download page at
    www.nvidia.com.


    I attempted :
    sudo service lightdm stop
    but this just shut my entire system / monitor off, and I had to do a hard-restart of computer.


    I have x11vnc installed.
    Could this be causing conflict?
    ======================================
    -- The "application select button" (similar to the windows menu icon) does not have a shortcut.
    This application menu in ubuntu seems to be a program called "whisker".
    How can I set a keyboard shortcut for "whisker" to launch it ?
    ======================================
    Is there a folder for applications ?
    Where I can sort and organise my applications by type etc.
    ======================================
    -- Lastly, and least significantly :
    I signed up to these forums as "Spazz", but it's made it "Spazz2".
    How can I eliminate the number?
    ======================================
    Thanks again !

    That would be the best way to do it, simpler for you and those answering you.

    Don't do that, see https://help.ubuntu.com/community/Bi...erHowto/Nvidia

    also, 18.04 doesn't use Unity anymore. and you are messing up your desktop (as you noticed) by doing entering some "random" commands without knowing what they will do on version 18.04.
    Read the easy to understand, lots of pics Ubuntu manual.
    Do i need antivirus/firewall in linux?

    Unity is no longer being supported. The versions of Ubuntu that had it and are still supported will continue seeing updates as bug fixes and security updates but Unity is no longer on anything past 18.04. The closest thing to Unity is to get Gnome. Even the new versions of Ubuntu that ship with Gnome actually run a custom setup with a nice dock that is similar to that of Unity. Totally worth checking out. I have it installed on my main rig running 18.04 and it's really nice. Granted I've got half decent hardware. My little thinkpad x131e is also running it but this UI is a bit much even if it is still stable.

    Ubuntu 18.04 doesn't use unity as default but it is easy enough to install (yes it is supported by the community)

    Code:
    sudo add-apt-repository ppa:unity7maintainers/unity7-desktop
    sudo apt update
    sudo apt install ubuntu-unity-desktop
    sudo apt install xserver-xorg-input-synaptics
    Choose lighdm instead of gdm as default.
    reboot.

    The ppa is not necessary as all packages are in the repo, but it fixes some bugs since 18.04 was released. I have a few 18.04 installations running unity, much faster and smoother than gnome shell IMO.

    Thank you oldos2er !
    Yes, I read back on my OP, and it is a horrible wall of text. I think I just wanted to get all my questions out while I think of them.
    Will make separate posts.

    Thank you for your advice on the driver.
    I will try and learn how to deal with binaries.

    Thank you mastablasta !
    Yes, I think I have messed up desktop a bit.
    I didn't think it was random commands that I entered. It was the commands that I mentioned above, from the article I mentioned, which didn't seem unreasonable that it might work.
    I thought Linux / Ubuntu was configurable and backwards / forwards configurable in that way : But clearly not?

    Is there a way I can undo completely what I have done ?
    Like is there some kind of console history ?
    Or do I need to reinstall the whole O/S again ?

    I note that in terminal, there is a history of many of the past commands I have entered, even after I have powered system on and off again.

    I really only entered the commands I mentioned in my OP from the article I hyperlinked, so if there is a way for me to reverse these commands, would be easier than an entire system reinstall for what seems like a tiny thing.
    Thanks anyway for your reply.

    Ubuntu MATE has, besides a "Redmond" and "Cupertino" DEs, but "Mutiny" gives you a pretty close DE to Unity.

    I do love the name.

    Re: Many newbie Q's. NVIDIA Display Drivers, Dash, Unity bugs, general use

    Thank you Angisky !
    I am glad to know that it is possible for me to install and test Unity !
    (Although I think the installation procedure I have tried has given me problems).

    I am mostly interested in the "dash" feature of unity, which seems to be absent from stock installation of Ubuntu Studio 18.04, as far as I can tell.
    Dash looks very similar to the spotlight feature in Mac OSX, which I love.

    Ideally if I could have that alongside the stock XFCE desktop which has the windows-style corner button, that would be excellent !

    Re: Many newbie Q's. NVIDIA Display Drivers, Dash, Unity bugs, general use

    Thanks monkeybrain20122
    This sounds like an excellent solution. I will give this a go.

    I would like to try to remove the bad-job I did trying to install unity previously, before installing over the top of it.

    I think I stuffed up my system quite a bit trying to install unity -- using the method in the article I linked to.
    I then tried to remove / purge that installation to restore my system to how it was, but this did not work either.

    I now get error messages after logging into the system, and this has coincided exactly with Chromium browser behaving very strangely for some reason (Many of my extensions seem to be dead for some reason).
    There were no other new variables I introduced between the time of installing unity and Chromium behaving badly (seems very strange, but that's the case).

    Can anybody spot any poor decisions I made in my bash history ?
    (I am a complete novice with Linux -- happy to research any answers given though) :

    sudo apt ubuntu-desktop
    sudo apt-get update
    sudo apt-get install --reinstall ubuntu-desktop
    sudo apt-get install unity
    sudo shutdown -s now
    sudo shutdown -r now
    sudo apt-get remove <software-name>
    sudo apt-get remove unity
    sudo shutdown -r now
    sudo apt-get purge unity
    sudo shutdown -r now
    sudo apt-get install --reinstall ubuntu-desktop
    sudo apt-get purge ubuntu-desktop
    sudo apt-get install xubuntu-desktop
    sudo shutdown -r now

    =======================
    Any assistance greatly appreciated.
    Thanks ! (:
