Install ubuntu desktop how to start Unity?

LMH1

Hi i tryed to install from kubuntu:

sudo apt-get install ubuntu-desktop

Tryed to reinstall ubuntu-desktop

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

rm -rf ~/.config
rm -rf .compiz-1

But still i only get a steam icon, nothing else.
do i need to make boot script unity or unity-2d-shell?

Or is that a bug in kubuntu?

KDE\XFCE 4 works nice.

You need to apt install ubuntu-session aswell.

If you add that package you should get a selection dropdown in lightdm/KDM (normally a little cog next to your name) that will allow you to start a Unity session.

LMH1

So i did not need to:

sudo apt-get install gnome-session
sudo apt-get install lightdm
sudo apt-get install unity-greeter
sudo dpkg-reconfigure lightdm

This is only if you command did not works?

Do you also know
Sudo apt-get install xfce-goodies
Is it a part of apt-get install xfce4-desktop?
Or is this package outdated so not longer in use?

Sudo apt-get install xfce-goodies
Is it a part of apt-get install xfce4-desktop?
Or is this package outdated so not longer in use?
That package contains a lot of extras to the xfce4-desktop so if you do not already use either xubuntu-desktop or xfce4-desktop there is little point installing it. If you do decide to install it you will end up bringing in a large number of other xfce4 packages and will probably end up with a very confusing menu system with a lot of alternative text-editors, file-managers, etc etc available to you.

So you have Kubuntu, Ubuntu (Unity) and Xfce all at the same time? I’ve read of many instances where Kubuntu and Unity seem to “clash”. Same with Unity and GNOME. Re. Xfce, some people get all excited about how the notifications appear “different”.

CantankRus

The unity plugin for compiz may not be enabled.
Reset compiz to default via terminal…

dconf reset -f /org/compiz/
Logout….

kill -9 -1

You can run the command from your xfce session if you can’t access a terminal in the Ubuntu session.

LMH1

I tested:
sudi apt get install ubuntu-session
sudo apt-get install unity-greeter

But still same issue, only steam icon, without unity.
I want to test many desktop, i know this works better before?

computer freezes every time I go to iflscience.com

walterramjet

I dont know if its something wrong with my computer or that website. I recently installed an app that posts how much memory is being used by each tab in Firefox 45.0 and it says that “http://www.iflscience.com/space/titans-highest-mountain-found-cassini-spacecraft” was using about 135MB just before everything went gray and no response from mouse or alt-tab or keyboard or anything. This didn’t happen before recent upgrade to linux-image-4.2.0-35-generic. Anyway, i dont know if I should complain to the website or here or if some other place, please let me know.

Thank you,

For me it loaded almost instantly but I had NoScript enabled. When I let NoScript run everything Ghostery reported 10 trackers and uBlock Origin reported five adverts. One of those scripts or adverts is causing you a problem.

ajgreeny

Also loaded instantly here, and I also use uBlock-Origin (stopping 10 items in my system) but I do not use no-script.

walterramjet

thank you for checking that. i dont know how to block scripts but i will look into it. thanks!

NoScript is a Firefox add-on. See here:

hitting f5 in firefox

Always.Learning.AP

when I hit f5 on firefox in ubuntu 14.04 it goes to google instead of refreshing my page. How do I make it stop this annoying behaviour and make it do what I want?

Is it a laptop?
Some laptops (and small keyboards in general) have a bunch of other functions mapped over the top of F keys that do different things, and you need to hold the [FN] (or equivalent) key to get to the proper f-key inputs.

You can usually reverse this in BIOS – so that it defaults to F1 – F12 instead of the “media” functions.

vasa1

+1.

If that doesn’t apply, try safe mode.

sammiev

F5 on my laptop refreshes the page on FireFox.

Works as should.

Nautilus 3.20 remembers last session

monkeybrain20122

In Ubuntu 16.10 nautilus has this “feature” of remembering whether hidden files were shown in the last session instead of hiding them by default. Is there a way to restore the old behaviour where hidden files are always hidden by default unless press ctrl+h or choose “show hidden” from menu?
——
mc4man

I don’t think so. In the past it was both a nautilus preference & an in nautilus one time action. Now it’s a “org.gtk.Settings.FileChooser” setting. So once enabled it stays enabled until disabled no matter how it’s enabled. (3 ways, menu, binding, dconf

I guess you could create a binding or context menu option to disable.

Solution to a thread posted in the development forum – User switching

kurt18947

As is usually the case there’s a solution, I just had to find it. The question was how to restore user switching that had been present in previous Ubuntu-Gnome releases but appears to be MIA in 16.04. The solution I came up with is a .desktop file that runs this:

dm-tool switch-to-greeter.
I also discovered an extension that works something like the ‘drawers’ app in Gnome 2 – QuickLaunch. There’s only one ‘drawer’ but I find that enough. Drop a .desktop file into its folder and the app is available via the QuickLaunch icon.

Edit: This appears to only works with lightDM according to Ubuntu Manpages.

Edit2: This is working great on a desktop with AMD graphics. I just reinstalled 16.04 on a Thinkpad (Intel graphics) and when I switch users, the cursor disappears. I can log out then log back in and the cursor re-appears. It does the same thing when using the lock screen method of switching users. I’ve found threads on the Fedora forums talking about this. I wonder if it’s a gnome thing?

Manual “Suspend” kills video but power mgmt “Suspend” works fine

Wadcutter

My wife has asked me to fix her Dell precision 490 desktop with Nvidia NV44 video card, 8 GB computer memory running Precise P. There’s also an 8 GB swap partition. The power management is set to suspend after 30 min of inactivity and that works fine. But if she uses the upper right corner button to manually suspend, it will ruin the display when it wakes from suspend. Then the desktop is distorted pixels, kaleidoscope colored lines, black sections, etc.

Her solution has been to try to avoid manual suspension (allow power management to do it) or completely shut down if she can’t do that. I played with it a bit and discovered that if the display is destroyed by using the manual suspend button, it could be recovered by going to the display System Settings and changing the resolution briefly. An undistorted desktop view appears, then it times-out back to the original resolution and everything is fine. It’s a viable workaround, but she doesn’t like it. She doesn’t want to always leave it to power management to put it to sleep or have to use workarounds if she uses the manual suspend choice.

“Hibernate” is not enabled at all and my experience has been to avoid it-“Suspend” works fine for most of our purposes. But I do see a lot of suspend problem posts here, but didn’t fine clues about why the manual choice is defective.

Lxde doesn’t “follow” when Openbox is resized in 16.04

franter

Hello,

Wanted to try Lubuntu on our little TV-PC instead of old Windows XP, but the desktop was too big for the screen. Happily Openbox can easily be resized exactly to fit the screen, but the LXDE desktop didn’t “follow” the Openbox resizing and most of the Lxde menu is under the screen. Is there a way to get LXDE to “follow” Openbox when Openbox is resized to fit the screen?

One solution would be to choose a pure Openbox distribution, or install Openbox from Debian, but I quite like Lubuntu as I’ve used it quite a lot for some years.

DuckHook

What do you mean by “TV-PC”? Please describe your HW in detail, since your difficulties seem to stem from the interaction between your OS and this particular HW. For the sort of info we need, please see the link in my sig: How to Ask for Help

Please also rephrase what you mean by:
…the LXDE desktop didn’t “follow” the Openbox resizing and most of the Lxde menu is under the screen. Is there a way to get LXDE to “follow” Openbox when Openbox is resized to fit the screen?Purely as an educated guess, I surmise that you are referring to the common overscanning issue, especially in light of your prior reference to a TV. If this is indeed the problem then, first, try turning off overscan in your TV settings. On some TVs it’s not called “Overscan”, but something else. You can Google how to do this for your specific TV model.

Note: XP is long past its end of life and is now a huge security hole just inviting you to get owned by some nasty scumbag prowling the Net. Either install some form of Linux or at least upgrade to Win7, which is still in support (though it’s getting long in the tooth too).

It’s possible to log in pure Openbox in Ubuntu, but the forum software does not allow me to explain how to do that.

EDIT Here’s a screenshot of how to do it (this is the login screen of a Xubuntu system with Openbox installed):

Some posts on the Openbox session of Lubuntu: https://ubuntuforums.org/showthread.php?t=2173126

buzzingrobot

Openbox is LXDE’s window manager, i.e., the thing that’s responsible for drawing, moving, resizing, etc., the windows open on the display. So, there is no single “Openbox” to resize.

Hard to know without some info, but perhaps the display size is being set incorrectly?

franter

The HW is a Zotac Mag, Atom processor and Nvidia ION. The screen is a Panasonic plasma screen with full HD, and no it doesn’t feature any overscan system that I know of.

Well I expect you all are young and don’t remember the days when HW wasn’t as automatic as today and that resizing the desktop was quite standard.

Openbox can easily be resized so that the window exactly fits the screen. This is also possible in Windows XP and prior versions, but as Windows is getting more and more Lite I don’t know for later versions. Mac OSX hasn’t this feature as I wanted to use a Mac Mini instead.

Back to Openbox, I’ve made the window to perfectly fit the screen, but the LXDE menus are not affected by the resizing of the Openbox window and stays mostly out of the screen.

In Windows or OSX his would clearly be a bug, but as in Lubuntu Lxde comes on top of Openbox maybe there is some way to stick Lxde to the Openbox window.

In the Lubuntu start menu, under “Preferences” there is an “Openbox Configuration Manager”, so there is clearly a single Openbox to resize as I had no difficulty to resize the Openbox window to exactly fit the screen. But while rezizing Openbox the LXDE menus don’t move at all, they stay mostly out of the screen. In Windows or OSX I would call this a bug as the Lxde menus should follow the Openbox window, but maybe there is some setting to make this possible?

Shut down button in cinnamon

juancompadre

Hello, I am using ubuntu 14.04 with cinnamon 2.8.6 and when I press the shut down button, it appears a window where I can only press cancel. Before this problem happened, in this window I could choose to shut down, restart and suspend. I have reinstalled cinnamon and the problem is still there. When I use unity or gnome I don’t have this problem, it only happens with cinnamon. Any ideas of how to solve that?

Hello and welcome to the forum. I like the Cinnamon desktop myself and solved the problem of using it with ubuntu by switching to Linux Mint 17.3 where it is the default DE. Mint is based on ubuntu anyway so it’s not a big change.:)

juancompadre

Hello, thanks for the answer. Yes it can be a good option for a future installation but I don’t think I should change my entire linux for a little problem like this.

Num lock turns off on Xubuntu 16.04.1 before logon

kahukowhai

Well. I know this topic has been canvassed many times in these forums. Some workarounds of this issue have been posted, some of which are version dependent and/or cause other problems, mostly using a program called numlockx.

I just want to see if this is a forum issue or should it be a bug report issue.

I have used Linux Mint, Lubuntu and Debian Jessie and in all of these related distributions, the num lock is not being turned off before logon on these distributions. (Naturally I have checked to see that the Num Lock is being turned ON in the Bios)

Therefore this problem appears to be specific either to Xubuntu, or Xfce, or some other component.

I have gone through the OS specific settings, many of them, and have also attempted to discover a workaround using the numlockx program. But as I do not know much about how to get specific startup applications to run, before logon, I don’t know of any way of running this program to set the Num Lock to On before the login window appears.

Dennis N

Maybe login screen setting for Num Lock is set by lightdm (which is not your user session). numlockx would not run until after you login anyway.

Unity is very sluggish in Ubuntu 16.04

vasiauvi2

Hello all,

I have upgraded to Ubuntu 16.04 several weeks ago (I am upgrading since 14.10, no clean install) and Unity was working O.K. After some updates, that I don’t remember now what were, Unity stopped working correctly. No Unity is very slow, practically unusable.
Here (https://lh3.googleusercontent.com/X08QCP3DUuyDC7dmy8Z6PwDpTR4NGpYFySSG4eEI2Fn563Nhmq WiimKhCE0stPebwMKFHrr2vBWu8zmNaUqYvf1rrAezTZs9Aptp ZT6pT6KiDbIl6LBk-aUiC4ackAUY9zzWwykcyCwKJLdysSRJmWun4RKdcqcN5ba_bLq muMlsxA3P1_TKpDsu546Zp584YyZ74LmDbnNdjaIv_A6PrE2N3 NTrY4z9EI4U9sp8wX5jqPN81bw1UQwVFxRXkLIlvJkYFogdwis mGBUTlkJ8wvWHaN-k8tlyB4dGdnRMgHTG7ULiNXQFQ_QwV4tWbvSgs2ENux8baTTIq SnZXCjypJWkztDZ8vilnBfDlizbkXr8MWOb-iSWHYeiqA3XnsMXcDSEIE2yMLSvaPNu7olSnTCwfLE-5MKtQk-WwN759LSvej_OSC6W3Uxp-jlrV23uKCIshEmA9I0BSW9MIKwkrqXvUiBFOjRsMifz2Vgk9nq MoAxHy7bM5RyUWTq8A9h1voAQ8dGLHNb_1ZpqYV2dJewBVXLgI 3YkQRsWGUVqXpImqhgZG5Fp_XkW5vzava7EAvPrkZRQSQc2Pab wmeZes5IHVgIqxqM=w866-h649-no) is a picture of the desktop after logging in.
I’ve installed Cinnamon just to use my laptop and it’s O.K. but I would like to use Unity.

Edit: resetting Unity doesn’t work.

Does anyone has any idea how I could make Unity work?
Thanks.

RobGoss

Hello and welcome, What are the specs for your machine? just by looking are that screen shot I would have to say it has to do with your graphic card

Maybe try a lighter version of Ubuntu like Lubuntu (http://lubuntu.net/) or Kubuntu, (http://www.kubuntu.org/) might be a good option they use less resources

mörgæs

Reinstalling Ubuntu is also an option.

vasiauvi2

Thanks for the reply. I’ve used Ubuntu for some time now and Unity was working correctly. I’ve remembered that I’ve removed Gnome 3 (from staging PPA) and maybe that’s why Unity was, somehow, damaged. I’ve installed back Gnome 3 and now also Unity is working.
