Ubuntu 19.04 – blank screen after boot

I was able to us my Ubuntu 19.04 installation without any problems, but today while working it started to act strange. Every command I would enter into the terminal resulted in permission denied. So I decided to reboot.

I would then enter the password to decrypt the partion, and then it would go to a blank screen, sometimes with a static _ in the upper left corner.

Things I’ve tried

Changed /etc/default/grub from


Tried purging nvidia. But nothing was removed, presumably because it wasnt installed.

So try I tried install nvidia with sudo apt install nvidia-driver-390.

This slightly changed the result, but only slightly. Now the screen is almost blank, with the exception of a green OK in the corner.

However, on subsequent reboots I now no longer get the green OK. I just get a static _.

Output from hwinfo --gfxcard --short:

nvidia GP107M [Geforce GTX 1050 Ti Mobile] Intel UHD Graphics 630 Mobile 

I tried sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.mybak but get /etc/X11/xorg.conf no such file or directory.

Tried sudo apt-get remove --purge nvidia-*. And this uninstalled a lot of stuff!

Tried sudo apt-get remove --purge xserver-xorg-video-nouveau but this E: Unable to locate package xserver-xorg-video-nouveau

Have to Power Boot Twice to Load Lubuntu 18.04 on old 32-bit Dell Laptop

I have an old, 32-bit Dell Inspiron 1505 laptop that had been running an earlier version Lubuntu. I recently installed Lubuntu 18.04 and it initially worked. Then, following a major software update to that re-installation (45 minutes), an unusual boot problem occurred. Problem Statement • Press power button once: Dell splash screen > brief flash of dim background light > Grub menu appears > screen remains black for as long as I let it sit there, but the power indicator light remains ON. So power is on but with a black screen. • Press and hold power button: brief flash of dim background light > power goes OFF. Power indicator light OFF. No power to the laptop. • Press power button a 2nd time: Dell splash Screen > Grub Menu > blinking cursor > /dev/sda1/ recovering journal, followed by a minute of messages for starting various services and modules > Lubuntu desktop opens. Power light ON, hard drive light OFF, until I open a browser; then the hhd light turns ON. • So, I am able to access the GRUB menu on the 2nd power boot and open Lubuntu • I can boot from either the USB or DVD options, and from a Live DVD USB or disk Actions Taken so far: • I have run ‘Boot Repair Disk’ twice. I have posted its report at http://paste.ubuntu.com/p/WZdNGXKWzG for further info. • If it matters, the battery on this laptop is no longer taking a charge. • I have run MemTest+86 and hard drive S.M.A.R.T. tests, and they show no errors • Sda1 is using the ext4 file format. I have researched this problem and identified several potential solutions: 1. Edit Grub file and replace ‘quiet splash’ with nomodset 2. Use a different kernel (I only have 1 on the Grub menu) 3. Disconnect a USB mouse (didn’t help) 4. Substitue gdm for lightdgm as default log in manager (how to do this?) 5. Boot into a recovery mode and run fsck 6. Examine the /var/log/dpkg.log for errors 7. I have read there is a bug with Lubuntu 18.04 on 32-bit systems So if Grub menu works, power to the laptop is on (on 2nd power button), and hardware is not an issue (hhd and RAM tested good), then at what point does this boot problem occur, what does ‘recovering journal’ imply, and how do I fix it? It seems to me to be a software, rather than a hardware problem, but any suggestions would be most appreciated to this highly frustrating boot problem. Thanks.

Cannot boot Windows 10 after Ubuntu installation

So I was having this idea that I’ll install ubuntu 18.04 alongside my already working win 10.

Keep in mind that I have two older discs (MBR) and legacy bios – main disk 1 TB. On my main disk a made some free space, shrank size making 50GB of free space for Ubuntu instalation. I installed Ubuntu from usb and after that it asked for reboot so I did that. And that’s where first problems appeared.

First, I was not able to boot back to ubuntu at all. After some tinkering I found out on the internet that I should be using EasyBCD as boot manager. Did that, added ubuntu, corresponding partition and I got it. Reboot, boot manager loads fine, win10 working as it used to. But when I tried Ubuntu, I got stuck on black screen with flashing cursor. Was not happy with that. Went for reinstall as someone suggested that something might install wrong. So I deleted the 50GB partition (made free space again) and reinstalled Ubuntu back.

This time really something was running differently. First Ubuntu boot manager welcomed me with all various choices. (Ubuntu, recovery mode, win10 on older disc and win10 on main disc). Tried ubuntu, everything was running flawlessly. But when I tried to boot back to Win10 on my main disc, boot manager appeared with my message that I should repair my pc. And following \NST\nst_linux.mbr is missing or error in it. From this point I cannot really move further. Ubuntu is still running fine. I’m able to run Win10 on older disc but when I try to boot using main one it ends on this message.

I’ll be very greatful if anyone provides any idea how to fix my problem without scraping main storage.

I had an idea if there is some interference with ubuntu boot manager and EasyBCD that is surely still working on the storage. Also I went through the directories via ubuntu bash and at this point I did not lose anything from the main storage.

Ubuntu 18.04 hangs on boot

After upgrade, I can no longer boot Ubuntu without recovery mode.

I have been using Ubuntu 18.04 reliably in VMWare Fusion on my Mac for years. However, after installing a update a month or so ago, the system hangs with a purple screen and a faded Ubuntu®.

The only way that I can boot is to go into recovery mode through GRUB: Ubuntu with Linux 4.15.0-54-generic (recovery mode)

The dpkg repair fails because it could not resolve us.archive.ubuntu.com, even if I enable networking beforehand.

I applied this update to two different systems at the same time (one modern desktop and one old laptop, with different versions of OS and Fusion), and they both have exactly the same boot-up problem.

It is annoying to have to go through the recovery mode in order to boot up Linux. Is there any way that I can run some magic incantation so that it boots up into the login window again?

I can’t boot to Flash Drive containing Ubuntu

I’ve used Rufus to create a bootable pen-drive with Ubuntu 19’s ISO. Then going into BIOS and selecting USB to boot first (Not UEFI option of the same), then I received this error: https://imgur.com/s4Rzb9I

I contacted a Discord server for help. Its administrator said me to try 18.04 version instead. I did the same process with Rufus, now following this tutorial: https://tutorials.ubuntu.com/tutorial/tutorial-create-a-usb-stick-on-windows#0.

Then booting by the same way I received this error: https://imgur.com/etezYw5

After this I’ve tried to put this same USB with Ubuntu 18.04 in another computer, which I don’t have the specs to show, only saying that the specs are lower than my actual computer. In that another computer, the error was this one: https://imgur.com/FKjqKgc.

I’ve hashchecked the ISO in the two cases, all hashs was the same as official provided by Ubuntu’s website.

Installing Windows as dual boot on Linux computer

I am currently having my Dell XPS13 with Ubuntu 18.04.2LTS installed, and I am very happy with it (mostly doing dev stuff). Right now I am using a Windows VM whenever I need to use Windows application.

However the amount of applications without Linux support I have to use is growing so I decided to set up a dual boot system.
I installed a dual boot setup based on a Windows machine before and I read that this is the recommended way is to:

  1. Install Windows
  2. Add Ubuntu

So I was wondering what the best way is to realize this setup while keeping everything from my Ubuntu system (files, applications, …).

My thought is that I’d have to completely clone the system and create an .iso and use this one to install Ubuntu instead of the default one.

I just wanna know if any of you have done this before and what your process looked like (before I completely mess up my system).

Or at least I will create a backup so I can restore my Linux enviroment at any time.

Doubt on boot options – Installing ubuntu on a second disk

I have windows 10 installed in my SSD as my main OS and just installed Ubuntu 18.04 in a separate hard drive. At the moment the PC would boot windows automatically. If I want to boot Ubuntu I have to select it directly on the BIOS.

The thing is, in the BIOS says that ubuntu’s bootloader is on the SSD (it says something like Ubuntu: P1 Kigston…). Have I done something wrong during the installation?

PS.: While installing Ubuntu, the option “Device for boot loader installation” i chose was the same one I was attempting to install the system (HDD).

On Boot up, Lightdm does not work and black screen appears

I updated ubuntu 16.04 LTS to ubuntu 18.04 LTS. On ubuntu 16.04 I was using gdm3, which got broken during upgrading because when I set gdm3 as default display manager in recovery mode through,

sudo dpkg-reconfigure gdm3 

it said “gdm3 is broken or not properly installed” so I set lightdm as default display manager.

Now, when I boot having lightdm, after the purple scree, the black screen appears and nothing happens. If I press Ctrl+Alt+F2 , it shows me the tty3 login screen. I login with my username and password. Sometimes, it accepts it and sometimes it doesn’t (which is an issue but not the major issue of this question).

After logging in, I can navigate my directories but I can’t open graphical window. I tried opening chromium using command “chromium-browser www.google.com” but it said something like “Graphical interface not permitted”.

How do I get my Graphical Interface back? Note that I can’t connect to wifi. I tried using

sudo ifconfig wlan0 up sudo iwconfig wlan0 essid name key s:password 

It gave error in setting password which was like “Invalid argument password, Set encode”. I tried giving hexadecimal password too without s:

sudo iwconfig wlan0 essid name key hexpassword 

Didn’t work either. How do I get my UI back? And can the internet be connected through ethernet?
