I have installed Ubuntu Server 18.04 on an old notebook for home purposes (SAMBA, Transmission, etc...). When I open it, it shows me . It remains for about 2-3 minutes and it slows the boot process. How can I remove this screen?

I've just installed Ubuntu 18.04 and I want to disable the lock screen.   I don't want to see it at all, neither on power-on nor after suspension.    I tried:      Settings -> Privacy -> Screen Lock -> and changed 'Automatic Screen Lock' to 'Off'.   The lock screen still appears after suspension. Any suggestions?

After installing Ubuntu server how do I install the desktop environment?

First of all: Yes, I ran sudo update-grub after changing the value.  After a new install of Ubuntu 18.10 on an empty disk the wait time at the grub menu is of 30 seconds (half an eternity!).  The line GRUB_TIMEOUT in /etc/default/grub had a value of 0. Changing this to 10 did not change the wait time, it was still 30 seconds.  Any ideas?

What are your tips for improving overall system performance on ubuntu? Inspired by this  I realized that some default settings may be rather conservative on Ubuntu and that it's possible to tweak it with little or no risk if you wish to make it faster.  This is not meant to be application specific (e.g. make firefox load pages faster), but system wide.  Preferably 1 tip per answer, with enough detail for people to implement it.  A couple of mine would be:   Install  (via Software Center or sudo apt-get install preload); Change  value - "which controls the degree to which the kernel prefers to swap when it tries to free memory";   What are yours?  PS: Since this is not intended to have a unique answer but rather, several useful tips, I'm making this community wiki out-of-the-box.

See this   I have this on my Lenovo s205 too.   Is there some way to remove "ubuntu" from the menu? I don't even have it installed anymore.

I just installed Ubuntu 14.04 on a Dell laptop with 1.7Ghz Pentium M and 1Gbyte memory.  Graphics are Intel® 852GM/855GM x86/MMX/SSE2, OS type is 32bit.  The whole system is VERY slow. When I launch the applications manager, for example, I need to wait in order to see the letters I typed appear!  It is as if the CPU was overloaded and no memory available, but I only have Firefox running.  How can I make the system run smoother? It used to have Windows XP installed and it worked fine.

This is tricky. I would like to install Ubuntu on a machine that is intended to work as server, and for some reason I do not have an option to connect a screen to it.  I expect this may be similar to remote installation. However, there is currently no OS on that machine, so I will have to set up everything from scratch.  On the other hand, I do have a physical access to that machine. Therefore I can get it to boot from a CD/USB. But that's not enough.  Is there a way to do such installation remotely? Is there a version of Ubuntu image that comes with a SSH server preinstalled, and starts it once booted, so that I can boot the machine with such image, connect to it via SSH and process the installation from a different computer?  If not, what other options do I have?

My relatively fresh Ubuntu 19.10 on a top notebook is running flawlessly, but some applications are really slow to start. For now it's keepassX, filezilla, deadbeef. Both takes about 30 seconds to show it's window, but after that both are blazing fast as others. May be someone can help me to find a solution?

On my machine booting takes more than a minute which is annoying when I see that Windows 7 boots in 20 seconds.  Here is what I get when the machine is booting.    How can I see what happens when booting up?

Please help! I have 3 desktops and 1 laptop and bring the laptop everywhere and keep the 3 desktops at home and they all have Ubuntu on them and I would like to access media and any kind of files I have on all of them through or with my laptop when I'm traveling! All 3 desktops and 1 laptop are all 32 bit systems! So how can I install and run Ubuntu Server on 32 bit systems?

We have installed Ubuntu desktop edition on our development server. Now that we have it in a data center we would like to strip it down to a server edition.  Is there an easy way of doing so rather than just going in and uninstalling packages by hand?

I am just curious to know the time taken by my system to boot. In Arch Linux there is something like systemd-analyze.  What is the alternative in Ubuntu?

The latest version of Ubuntu server (18.04) seems to demand network configuration and refuse to boot without it. I have no desire to connect the server in question to the internet for anything, and have installed previous versions of Ubuntu server without network no questions asked.  Is a network connection an absolute requirement for the latest version of Ubuntu server? Or is there something I'm missing?  The installation cannot proceed past the network configuration page unless an ethernet connection is active, by my current estimates. I have no ethernet network within range of the machine so can't test it on an internet-less network. I only have WiFi within immediate range (which does have internet access) but it won't recognise the device and it should be simpler to get the installation to happen without any updates than to go to the effort of finding the drivers to support the WiFi adapter.  Note that this is NOT a duplicate of  since the new installer seems to be the real problem here.

I would like Ubuntu to automatically synchronize my system clock with a timeserver at startup.  However, my PC isn't connected to the Internet until after I've logged in (plus 5 - 10 seconds for good measure).  How can I set it to do this?

I just installed Ubuntu 18.04 and one of my first negative impressions is the long animation of flying-in icons when opening the app menu.  Can I speed this up or disable it?

Whenever I boot on Ubuntu, I see the entire GRUB menu by default. Is there a way I could make it simply auto-boot if uninterrupted within X seconds? I remember that this was the case on previous releases of Ubuntu, it would only show the GRUB menu if you held down a button during the boot.   How can I make GRUB do this by default and just get on with the boot process?
