When I boot Ubuntu 20.04 on my Lenovo x250 laptop, the display drivers seem to be gone. The only display is the "default" which is a very low resolution display 640x480.
If I connect to a second monitor, that is not recognized either

[ubuntu] A 20.04 post-install update caused login loop on a no-logon installation

May 19, 2020, 6:51 pm

I newly installed 20.04 on a fresh download three times on a previously-working 18.04 system which I completely wiped beforehand (had two bad upgrades on other machines so gave up trying to upgrade... they both worked with fresh 20.04 first time.) Even though I chose "Log on automatically", the system booted to a login anyways, with the dreaded "Login Loop" where entering my password just brought me right to the login screen where the ID is selected again. If I incorrectly entered my password it would tell me so; this was definitely a hosed logon. I checked the drive with Disks and ran a comprehensive S.M.A.R.T. test and the drive is fine.

When I re-installed a fourth time and did not check the box to download and install updates during the process, it then worked... system booted to desktop normally and did not prompt for logon. However when I then installed the prompted updates and rebooted, back to the logon loop. So some update between 20.04's release and the time of this post appears to be causing this.

I tried several fixes without success ie the .XAuthority permissions. The one that solved it was this:


  1. On the login screen, press Ctrl+Alt+F3.
  2. Log in to the shell using your username and password.
  3. Uninstall and reinstall the gdm3 package:

    sudo apt purge gdm3
    sudo apt install gdm3


In five or more years of a dozen Ubuntu and Mint distros on eight computers, this is the only installation issue I have yet noted. Hope that this helps someone.

New Ubuntu Server 20.04 LTS install will not boot

May 19, 2020, 6:53 pm

First I want to preface that this is an old box. The primary drive finally failed and while my plans are to build something new, I need a short term cheap solution until I can put everything together. Meanwhile, this BIOS/MB doesn't support UFI so it's got to be a legacy install. I don't know if this is the issue that I'm running into or not. The replacement drive is just a new version of what failed (WD Caviar 80GB)...

All of the drives are disconnected except for the new boot drive...

I have the Ubuntu server install image on USB, booting into that and installing to the single system drive I will configure it as the boot drive, then (usually) configure an 8GB swap, a 500MB ext4 /boot partition, and then everything else as ext4 / (root). I have also tried letting it just configure itself and use the entire drive. Also opting to just assign it as a boot device and create only the swap and / (root) partitions. In every case it reboots to the message: "No bootable device -- Insert boot disk and press any key"

All of my searches seem like it's trying to boot UEFI but this box doesn't support that option. Yet when the installer is starting up, I see the little icons at the bottom that look like some box/drive partitions "=" the little man in the circle and there are mentions that those mean it's booting into legacy mode.

I next tried using the Boot-Repair tool to reset the easy way (returns an error) then reset and reinstall grub using the advanced options and point it at the actual 20.04 install. While it doesn't give me any errors with the advanced repair, it still doesn't resolve the no bootable device error.

So as of right now, the most recent drive config is to have just the bootable, swap, and / (root) partitions, then I dumped the config report from Boot-Repair and that's at http://paste.ubuntu.com/p/ZMVKb5hGB9/

Is anyone able to take a look and see if they can identify what's gone sideways I would be most appreciative?

Thanks in advance

After some recent updates on gnome-shell-extension-desktop-icons you can now copy a file or application directly to Desktop!!! with copy-paste, not by dragging it with mouse.
You can also rename or delete a file on Desktop or copy-paste from desktop to folder window.

Rufus problem, what else can I use to burn iso to bootable USB

Hi, I was trying to use Rufus last night to burn an ISO to USB and ran into an issue. Rufus was trying to download some additional files before burning. In the logs it showed that Rufus couldn’t download these files due to an Outdated SSL on the laptop(a really old Windows XP). The whole reason I’m trying to use Ubuntu is to give this laptop a new lease of life so the kids can both home-school at the same time. Is there any other programmes that I can use to burn a bootable usb. I tried google and found ISO to USB but the computer didn’t recognise the usb when I tried to startup.

[ubuntu] Cannot access newly installed SSD

Hi

I've upgraded an internal SSD (nvme) and installed Arch Linux on it on the first three partitions.
I use ubuntu to control access to the OS's on the disks, so after Arch installation I ran update-grub on Ubuntu.

Arch shows up in the OS list at boot time, with the correct location, but when I click Arch it says that the device (UUID number) does not exist.

Windows is also installed on the same disk as Ubuntu and I can access that with no problems.

I can mount the new disk partitions from Ubuntu and the Arch files are present, where they should be.

I don't understand why are can't access them at boot time.

regards

jb.

[ubuntu] F2FS multidrive installation

So I'm trying to take advantage of the F2FS multi drive capabilipties, which will basically will let F2FS
see 2 of my drives as one .
The 2 nvme drives are formatted to the f2fs file-system with a partition created in each of the drives.
Then I run the command: sudo mkfs.f2fs -f -c /dev/nvme0n1 /dev/nvme1n1, and the format is successful.
The problem is that the installer doesn't detect the new 'volume' but still see the 2 disks as separate entities.
Is it possible to make see the installer the 2 drives as one? If so how do I do that?
F2fs-tools is installed, in case anyone is wondering.

[ubuntu] Ubuntu 20.04 installation problem

May 20, 2020, 7:35 pm

Could I have some advice on how to install Ubuntu 20.04 over Windows 10? I have been using Ubuntu for some 15 years and have installed, uninstalled, reinstalled many different editions and flavors of it. Last week I made a clean install of the 20.04 edition in my laptop and it works flawlessly. Now I want to do away with W10 on my desktop and have Ubuntu instead. No dual booting.
But installation always stops and freezes at "Installation Type" screen. Instead of the usual options of what you want to do with Ubuntu, I get a blank, frozen screen. If I try and click on one of the fields, then I get from the background a message "Sorry Ubuntu 20.04 has experienced an internal error etc". The only possible way of moving forward is to turn off the computer, which of course stops the installation process.
My machine is a Dell Inspiron 2530.
I once got an error message "Install Ubuntu 20.04 is not responding" and the option to "Force Quit" or "Wait". Nothing happened when I waited.
Windows 10 boots with no problem from the USB drive. The USB key is not damaged either.

[ubuntu] Expected consequences of upgrading Ubuntu 18.04 -> 20.04

Hello Gurus!
I consider myself as a rookie in Linux and have started using Ubuntu 18.04 (Gnome) as my default OS only few months ago. So far I've hardened my system, configured and customized it a bit and installed over 40 applications. Most of them are well-known FOSS and many are security oriented.

I'm now thinking to upgrade from 18.04 to 20.04.

My question is that, is upgrading Linux (Ubuntu) "business as usual" or should I expect any problems with e.g. any configurations I've done so far? How about with any installed applications? Should I expect any critical errors or conflicts, e.g related to booting etc.? I'm going to backup my configurations and system files with Timeshift and I don't have any personal files stored (e.g. videos, photos etc.).

My configurations include:

Enabling default disk encryption during installation
Configuring IPvanish VPN
Firefox customization
Enabling Night Light feature
Installing Curl
Tweaking with Gnome Tweaks and Unity Tweak Tool
Installing exFAT support
Setting static IP
Installing Kali VM in Virtualbox
Configuring Wazuh HIDS
Forwarding syslogs to my NSM
Enabling GNOME "minimize" icons feature
Enabling backups with Timeshift

My installed apps are following:

pCloud
KeePass
Veracrypt
Timeshift
GUFW
GParted
GVM (OpenVAS)
Wireshark
Authy
Signal
Brave
Tor browser
Nmap
ClamTk
Lynis
VirtualBox
Testdisk
gWakeOnLan
Pinta
Etcher
Viber
Gnome Tweaks
Unity Tweak Tool
Fast
VokoscreenNG
VLC
Kdenlive
Steam

Ubuntu crashes after password input in login

Hello and good day.

I've seen some similar problems in here but after trying all the mentioned solutions I am still not able to solve this.

I am running the latest version of ubuntu 20.04 and everything was working fine. I ran into some memory allocation problems (didn't have much) and erased the /home partition since it is possible to run everything from root. When I enter the password in my session ubuntu freezes. My machine is using a CPU AMD Ryzen 5 3600 hexa-core-3-6ghz-c-turbo-4-2ghz and a GPU Radeon RX 5700 XT Gaming OC 8G.

Some threads with the same problem indicate it might be a driver problem, I followed all the mentioned answers and still doesn't work.
Following this (https://unix.stackexchange.com/quest...gin-start-page), also still doesnt work (starting linux in recovery and acessing root terminal)

apt-get update
apt-get install xserver-xorg-input-all
apt-get install ubuntu-desktop
apt-get install ubuntu-minimal
apt-get install xorg xserver-xorg
apt-get install xserver-xorg-input-evdev //couldnt here
apt-get install xserver-xorg-video-vmware

reboot

neither works sudo ubuntu-drivers devices

It is important to mention that when I add the password and it freezes I can move the mouse. And when I go to restart it appears that one user is logged in. So I guess gettin in worked

Any help?

Updationg from 18.04 to 20.04 completely ruined my displays

Hi,
I'm a user of Ubuntu from version 4 and a Linux user since 1993(my first linux wad version 0.99) and strtint with version 10 (I think I steadily upgraded t the nesxt LTS version. Now, however did the upgrade ruine my display settings in such a way that I cannot solve it myself.
Hardware:processor AMD FX(tm)-6300 Six-Core Processor Memory 16 Gb Graphics Nvidia GeForce GT 610.
1 After upgrading the whole system didn't restart but immediately entered rescue mode saying that some file_filter-eyc. couldnt be installed.
My remedy was to start from a rescue USB stick and do a boot-repair. That at least repaired grub. However not all was well as I am used to work with 2 monitors and the system starts only with one monitor and says "Monitor unknown". This I detected with the command Displays from: System _> hardware -> Displays. When I click "Detectmonitors" nothing happens. also my second monitor (which ia larger and therefore more in use) is not detected which is extremely inconvenient.
When I start Nvidia Settings A blank screen is displayed. apparently something is wrong with the X-setup but until now I haven't found out what. My v the nvidia driver installed is NVIDIA driver metapackage from nvidia-driver-390 (standard installed) but other offered drivers gave the same results. It is installed using System-> Preferences ->Hardware->Additional drivers.
I've tried many things, a o a solved a bug in the nvidia drivers (Bug #1768050). One other thing I have found is that the Sources for updating of the tag "Other software" still points to 18.04. Is that an error or normal behaviour.

Ubuntu 20.04 black screen after grub on Lenovo Yoga C940 14"

I am stuck trying to boot the live USB to install Ubuntu 20.04 on a brand new Lenovo Yoga C940 14" laptop. The machine boots to the grub menu. Regardless of options, even trying to boot safe mode with nomodeset and removing quiet and splash, I get a black screen after the grub menu.


  • Ubuntu 18.04 desktop boots but does not see the WiFi
  • Ubuntu 19.04 desktop boots but does not see the WiFi
  • Ubuntu 19.10 desktop throws a black screen after the grub menu
  • Ubuntu 20.04 desktop throws a black screen after the grub menu
  • Ubuntu 20.04 server throws a black screen after the grub menu


On a whim, I tried turning secure boot off. That didn't change anything, of course.

I'm starting to think that the laptop needs to go back to Lenovo. It is super dumbed-down with almost no settings in the BIOS to even try turning off. Any ideas?

Unable to boot after 20.04 install on multiple O/S setup

I had a working ubuntu 16.04 LTS and windows 10 dual boot setup with spare space, so after booting up with a usb 20.04 image to ensure it worked fine I decided to install it to a new empty partition.
I now find that I'm unable to boot any partition, even after following various boot-repair tutorials.

My current boot-repair diagnostic file is on https://paste.ubuntu.com/p/9fc8q8hbpq/

My BIOS say's I have legacy mode enabled, but boot-repair claims it's set to UEFI. Don't understand why that is.
If I set UEFI (secure mode or insecure mode) I don't get any options other than booting the HD, which when selected just goes back to the error.

The message I get when the BIOS is set to legacy shows:

'System BootOrder not nofound'
'Creating boot entry "Boot0000" with label "ubuntu" for file "\EFI\ubuntu\sGNU GRUB version 2.04"'

I have tried the following from grub:
grub> ls
(proc) (hd0) (hd0,msdos7) (hd0,msdos6) (hd0,msdos5) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1)
grub> set root=(hd0,msdos1)
grub> linux /vmlinuz
grub> initrd /initrd.gz
grub> boot

this will take me to initramfs with the error "can't find /root in /etc/fstab"

I'm totally stumped, and would appreciate help on getting my O/S's booting agian.
Thanks.
