I get a black screen with the following text when booting Ubuntu 18.04.      GNU GRUB  version 2.02      Minimal BASH-like line editing is supported. For the first word, TAB       lists possible command completions. Anywhere else TAB lists possible       device or file completions.  grub&gt; _

This is what I see:  GNU GRUB version 2.02~beta2-9ubuntu1  Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.  grub&gt; _   What should I do now?

After running a VM and logging out, I got a black screen. I powered off and re-started but got the same after the bios option in start up passed. Several attempts went bye with the same result. So I fiddled with bios boot options a bit and was able to get to a different looking Ubuntu start up screen which, after entering pass key would run a series of commands that were too numerous and frantic to make out. They appeared to be overlapped/layered (the text that is) and seemingly repeating endlessly. I had to power down to get it to stop and re-booting just had the same effect. Finally, I hit the down arrow key when prompted for "disk sda5_crypt" at the pseudo Ubuntu log-in screen I mentioned before. This brought me to an all black screen which read something like:  lvmetad not active cannot process volume group "umbuntu-vg" unlock disk sda5_crypt**   From here I entered a password and Ubuntu start up ran.  That was an unsettling hour or so and I'd like to avoid that in the future. Any ideas what caused it and how to avoid it going forward?  Should have said this before but Ubuntu is the only OS on my machine and my optical drive cannot be opened manually.

When you are performing time consuming operations in bash like installing new software, is it possible to write text that will appear at the prompt when the operation has finished.  E.g   Imagine running:  apt-get install eclipse-platform   Then it will use quite a while to finish while you see the installation log, meanwhile I want to create new folders (workspaces) which Eclipse later will use.  Is this possible without opening a new terminal (or tab)?

In previous versions of Ubuntu I could create custom keyboard shortcut to run terminal commands, with something like gksudo reboot for example, and then assign that to something like win+r.  I can't find that option in Ubuntu 17.10 or Ubuntu 18.04 daily build.  Am I missing something?

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?

I have installed ubuntu minimal(mini.iso) on my vm. I then used recovery mode to login as root and create an account with useradd -m admin and then set a password with passwd admin.  When I login on the new account, instead of the normal prompt I only see a $ sign. If I try to tab-complete a command or file name it prints a normal tab. If I try to use the arrow keys it prints ^[[A, ^[[B, ^[[C or ^[[D. Also, ls no longer adds colors.  None of these problems were in recovery mode. How can I fix this?

I am running Ubuntu 12.04.  I cannot for the life of me get the grub menu (with options) to go away.  I would like it to auto-boot into the first option. I've edited /etc/default/grub so that it looks like the following:  GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2&gt; /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=""   After this, I ran sudo update-grub. Then I realized that I had grub 2, so I ran sudo update-grub2 (both make it look like they create the grub.cfg file successfully.  I restart my computer and it goes back to the grub menu and just sits there until I make a choice. This is not desirable if the power goes out... :-)  I also tried reinstalling grub using sudo grub-install /dev/sda - also unsuccessful

I'm brand new to Linux. I just installed Ubuntu as a dual boot system on my HP Pavilion laptop.  Where should I start? I've tried to play around with Terminal over the last hour or so, but I'm probably not helping myself out. Any suggestions are welcome!

I was installing ubuntu-Gnome 16.04 on my Asus ROG GL522VW laptop with an nvidia GTX 960m graphics card, and stumbled upon a problem.  After installation, I don't even get to the login screen. Instead my screen just freezes. I had this problem before, and got my answer in this post:   So I booted with nouveau.modeset=0, and everything boots just fine. But after I use additional drivers to install the NVIDIA binary driver - version 361.42 from nvidia-361 (proprietary, tested), I only get a black screen when I try to boot regardless of whether nouveau.modeset=0 is set or not.  While the screen is black, when I try to access the command line with ctrl + alt + f1 all I get is this: A start job is running for Hold until boot process finishes up (Xmin Xs/no limit) and no matter how much I will wait, it doesn't end and I have to reboot.  I followed the instructions in this post:   When I boot after reinstalling everything and choosing lightdm - it basically works but my login screen looks like a unity login screen, and when I insert my credentials it shows me a very bugged screen with all kinds of broken images with some of the things I had on my last boot, and after a few seconds my screen flashes on and off and it boots into my normal desktop, but still keeps spitting out system problem detected with only the option to close or report.  Also tried to install nvidia-355 and all kinds of versions, with no luck.  I wouldn't mind working with nouveau.modeset=0, but as far as I understand this disables my graphics card and doesn't utilize all of it's potential?  Any help or insight will be greatly appreciated. Sorry for the long post and if I should include more information please tell me what else I should include.  A huge thanks up front!  Edit: Reposted this question again and didn't know I can just edit the question to get it back up.  Edit2: Bumping again in a last effort to solve this issue  Please let me know if it is lacking information.

While trying to follow , I encountered the following error while attempting what seems like a simple sudo edit operation:  $  sudo gedit /var/lib/dpkg/status  ** (gedit:14898): WARNING **: Command line `dbus-launch --autolaunch=0bd873023a78bdb34ca1b9650000000b --binary-syntax --close-stderr' exited with non-zero exit status 1: Autolaunch error: X11 initialization failed.\n Cannot open display:  Run 'gedit --help' to see a full list of available command line options.   Running the same without sudo correctly launches gedit, but of course without editing ability. Does anyone have any idea what is going on?

What I want to achieve:  I want to customize my complete boot of my Ubuntu 16.04 LTS installation  to show the same wallpaper which is actually on my desktop.  What I achieved till now:   added the wallpaper to the grub menu by adding the following lines to /etc/deault/grub and doing an update-grub afterwards.  export GRUB_MENU_PICTURE="/boot/grub/wallpaper.png" export GRUB_COLOR_NORMAL="white/black" export GRUB_COLOR_HIGHLIGHT="black/white"  added the wallpaper to the splash-screen and login screen   Problem:  When I boot up the picture is showing while in grub, but then I rarely see the splash screen, instead I get an almost blank screen showing the file-system check like following:  /dev/sda1: clean, 201776/60878736 files, 4991277/243040256 blocks   This prevents me from having the boot experience I want to achieve since after that the splash-screen just shortly popping up after that message.  Question:  How can I remove this message from showing up so I get a seamless booting with my beloved wallpaper, without switching the file-system check completely off (if possible)?

Whenever I boot into my system, Linux directly boots. If I press shift, GRUB shows only Linux, not Windows. Here are results of fdisk and update-grub.

I am looking to get tab-completion on my command line aliases, for example, say I defined the following alias :   alias apt-inst='sudo aptitude install'   Is there a way to get the completions provided by aptitude when I hit the tab key? i.e. when I write 'sudo aptitude install gnumer' and hit tab, aptitude completes this to gnumeric, or if there was uncertainty lists all the available packages starting with gnumer. If I do it using my alias, nothing - no completion.

I recently repartitioned my HDD and I have damaged GRUB on my system. On boot I get the GRUB rescue prompt and I have to go through the following steps in order to boot normally:  set root=(hd0,msdos6) set prefix=(hd0,msdos6)/boot/grub insmod normal normal   (Those steps were found on another post on here!).  I'm very tired of repeating this on every boot, how do I permanently fix GRUB?

Each time I've tried to dual boot Ubuntu with Windows I always have difficulty with the same thing... editing the default option on the grub boot loader. I'm now running 11.10 and have run into the same problem.   Startup-manager didn't work on 11.04, neither does it work on 11.10. Editing GRUB_DEFAULT= in the /etc/default/grub file doesn't seem to work either.   This shouldn't be difficult, and I'm sure there's a simple explanation. Could someone please tell me what it is?
