I did a fresh install of Ubuntu 18.4 LTS, coming from Windows, and everything was working great! I installed my needed apps; I'll list them below in case they have something to do with the problem, and the system did an update. I rebooted and now the terminal is refusing to run. If I try and open it, all that happens is that it tries to load but stops after about 5 seconds or so. I've downloaded xterm so that I could use terminal commands again, but this has caused problems with updates &amp; installs as well.    I'd sincerely appreciate any help, I cannot seem to figure out what's wrong and I really don't want to have to reinstall the OS.

Tonight I upgraded to 11.04. Problems. Once I had finished the upgrade, I restarted my computer as it told me too. When I got past the ubuntu 11.04 (purple background orange dots), it simply went to the terminal and asked me to log in. I tried to restart the X server with "sudo service gdm restart" but no display popped up. I happened to have a few NVIDIA drivers in my downloads file also so I gave these a try, but the "install script" failed.   After all this I booted Ubuntu in graphic failsafe mode. I then decided to see what would happen if I removed the proprietary driver. Upon doing this and rebooting my Ubuntu booted into graphical mode "yay!". So without the Nvidia drivers I can finally see something other than terminal, but, I need those NVIDIA drivers for my work. So what can I do? I have tried installing the new NVIDIA linux drivers from the NVIDIA website, and have tried Installing the recommended driver via "additional drivers", but both have resulted in my being stuck in terminal.  If you can help or give me some advice PLEASE DO! I am really in a very bad situation...

Ever since moving from Windows to Ubuntu the experience has been pleasant. I don't miss windows, at all. Ubuntu 18.04 was my first choice.    However some pre-installed apps like Calculator, Characters, System Monitor and  System Logs do not start at all and I don't get an error. I usually delete them and install the same app but with a higher rating (stars) in the software centre. Has anyone experienced this and what could be the cause?     I unfortunately do not have logs. But the problem can be replicated by following these steps:     Downloading the official ISO from ubuntu.com     Using mksub to create a persistent live USB      Booting from said USB and attempting to open the apps mentioned above.    Edit: 23 Oct 2019  I used these commands to install mksub.  sudo add-apt-repository universe  sudo add-apt-repository ppa:mkusb/ppa  sudo apt-get update  sudo apt-get install mkusb mkusb-nox usb-pack-efi    I did not use a terminal to create the live usb with persistence. I used guidus. This was done from an ubuntu live disk created using Unetbootin on windows.

every time I start my terminal, it always says "-bash:  .: command not found" twice.  Does anyone know how I can get rid of that?

I'm working in a koding terminal running ubuntu 13.04, and I'm trying to run an application that requires an x-screen (even to run in terminal mode).  I am unable to connect with x11 forwarding, and I'm wondering if there is a workaround that will allow me to run this application (lmms).  $ lmms -v lmms: cannot connect to X server  $ uname -a Linux vm-2.masd.koding.kd.io 3.9.0-0-generic #4userns5 SMP Mon May 13 06:15:34 PDT 2013 x86_64 x86_64 x86_64 GNU/Linux $ lsb_release -a No LSB modules are available.

I installed Ubuntu 20.04 (server/terminal) from the Windows 10 app store, and then after launching the Ubuntu Terminal via WSL2 (Windows Subsystems for Linux) , I installed Ubuntu Desktop and did several steps to try and get a desktop instance of Ubuntu 20.04 launched.  In short, the steps involved editing the .bashrc file, installing Xming, and then attempting to open the Ubuntu desktop in Xming with the &quot;startxfce4&quot; command.  However, &quot;startxfce4&quot; just doesn't open the desktop for me.  I can get programs to open with &quot;grun&quot; and the file explorer to open with &quot;gopen&quot; though, so it is working partially. Does anyone have any alternative suggestions to how I might get the terminal to open up the full Ubuntu Desktop?  Obviously, this wasn't what Windows had in mind with WSL2 so this is kind of a reach, but any input would be helpful.  Could I somehow do this from the file explorer or with a program that could opened from &quot;grun&quot; or &quot;gopen&quot;?

It's all in the title.  Eg. if I have a gnome-terminal opened and I click on the gnome-terminal launcher icon, the running terminal will focus and no new instance will pop-up. Also, there is no item in the launcher icon's quicklist that would allow me to start a second instance of the program.

I've been using ubuntu for like 3 years as my main os. I've used terminal many many times but never have I deeply understand it. I run commands, I'm familiar with the basic ones, but i want to dig deeper. Is there any video introduction(i like to lay back and watch tutorials instead of reading books) to novice-intermediate to advanced command line?   Thank you.

What happened  I was working on my laptop while it upgraded from 15.10 to 16.04 (which I admit was a mistake) when suddenly the Unity overlay disappeared and the only thing on screen was the Firefox browser window. I switched to a new terminal, logged in and tried to run sudo service lightdm restart but instead of restarting correctly, the screen started turning on and off repeatedly, which freaked me out, so I physically turned off the PC.  Long story short: I forced a shutdown halfway through the Ubuntu upgrade.  Ever since, any attempts of logging in normally have been met with a solid black screen and the idle whirring of the CPU fan.  What I have tried  I have tried the recovery mode boot up, but no luck (The log does greet "Welcome to Ubuntu 16.04 LTS!"). I tried out each option that seemed useful:   dpkg goes through the packages as advertised, but strangely enough it always locks up on some Braille package until I do Ctrl+C, at which moment it spouts some error messages and then I think throws me into the normal boot. failsafeX results in a similar situation to the normal boot: a black void. fsck says the single partition I have is a-ok. grub seems to get a bunch of stuff. Don't know if it searches locally or fetches from the internet. network didn't work I think.   I tried following  but couldn't do the sudo part because the filesystem was mounted as readonly. So I ran fsck which mounts as RW and tried again.   This time, after running apt-get autoremove it went through many packages (Setting up foobar (X.Y.ZubuntuN) ...), sometimes installing packages, which I assume is the usual behavior. One thing to note though is it kept getting stuck several times, so I had to Ctrl+C it out of processing the current package. It finally ended on "Processing was halted because there were too many errors.".  While  seems to mention some of the graphics problems I've been experiencing... I have Intel HD Graphics, not Nvidia. I'll keep looking into it.

I use my computer for scientific programming. It has a healthy 8GB of RAM and 12GB of swap space. Often, as my problems have gotten larger, I exceed all of the available RAM. Rather than crashing (which would be preferred), it seems Ubuntu starts loading everything into swap, including Unity and any open terminals. If I don't catch a run-away program in time, there is nothing I can do but wait - it takes 4-5 minutes to switch to a command prompt eg. Ctrl-Alt-F2 where I can kill the offending process.  Since my own stupidity is out of scope of this forum, how can I prevent Ubuntu from crashing via thrashing when I use up all of the available memory from a single offending program?  At-home experiment*!  Open a terminal, launch python and if you have numpy installed try this:  &gt;&gt;&gt; import numpy &gt;&gt;&gt; [numpy.zeros((10**4, 10**4)) for _ in xrange(50)]   * Warning: may have adverse effects, monitor the process via iotop or top to kill it in time. If not, I'll see you after your reboot.

Trying to run a Ubuntu server for the first time... But everything is in a terminal. Is there a way to switch to a GUI?

First, I hope that this is not a duplicate, because I found my question quite strange and unique, and I don't have any idea with it.  These days I heard of the new Ubuntu release, version 13.10 and I am quite excited. I have been stuck in 12.04 for such a long time and it's time for a good upgrade. So...I ran update-manager -d and tried to go up to 12.10. (I decided to go up one by one) It took a very long time to download all the required kernel and packages...and soon installing...and some questions asking me if I want to replace the old config files. I did some tweaking with that system before (changing startup applications, TMPFS, zram-enabler, etc) and I thought that it will cause a real crash if I keep these config files. So, I replaced all of them but it goes too slow and it's time I've to go to school. I asked my grandfather if he could help me to click all the 'Replace' buttons for me and shut down the computer after the upgrade finished.  When I was back from school, he told me that he accidentally clicked 'Keep' for the last popup box, and my computer can't function now. The grub menu is still there (made it appear by using the SHIFT key trick), and the splash screen is still visible, and I hope that the login screen is still there, or at least the tty so that I can still do a rescue, but nothing worked. CTRL+ALT+F1 does nothing, and I am sure that the monitor is still functioning.  So what can I do now?

I've been running Alpha releases of Ubuntu for some time now. I keep running into issues - how can I get these resolved? What should I do when I encounter these problems? And where can I find other Ubuntu+1 users to ask questions?

I tried installing Kali Linux tools.  I started installing some tools and there were several things I had to "agree" to and one message said add users... something in terminal, and when I came back I saw terminal reporting removing a bunch of core programs that I needed. I canceled the process but I don't know if I should reinstall Ubuntu or not.  How can I repair my system?

I just upgraded my System to 14.04.  After restarting when the update was finished I did not see any menu bars or panels.   Right clicking and opening a terminal via ctrl+alt+t is not possible. However I can access the terminal via alt+F1. I already tried out installing the unity-desktop again but it didn't change anything .  Do you have any suggestions?

I tried to upgrade from Ubuntu 16.04 to Ubuntu 18.04. First, after downloading and installing of packages, I was unable to login. Login screen hanged completely and it showed Failed to authenticate. But then I logged into tty1 and then logged in Ubuntu. It was saying that I am in Ubuntu 18.04. Then it asked for reboot. So I rebooted Ubuntu from terminal. It got stuck at something like /dev/sda4 : Cleaning files. After trying for a few times, I got into tty1 and here I logged in as root user and tried to update and upgrade. But now I am getting errors like unmet dependencies and broken packages. I have done sudo dpkg -- configure -a. I don't want to do a reinstall of Ubuntu. How do I get access to my Ubuntu Desktop?
