Never had this happen on my setup. Have a nv3080 optimus with integrated AMD GPU though.

I don’t think I can help per say but it might help others if they knew a bit more about your setup.

1. Distro
2. Nvidia driver version nivida-smi
3. Kernel version uname -a
4. Plasma version plasmashell --version
5. KDE version Kf5-config --version

Those bits might help.

Obligatory, FUCK YOU Lars Ulrich!

Garida has the most polished easy Arch and fully tweeked KDE experiance i have found. I think that it is the best introductory Arch distro out there. Dragonized edition comes fully loaded with all your gaming needs packaged up in the distro. Comes with chaotic AUR already installed so most of what you want from the AUR is precompiled and doesn’t have to be built.

10/10 would recommend.

Arch

If you have 2 separate drives each with their own boot loader and you tell your bios to boot from the grub bootloader and grub has successfully detected another OS like windows everything will be fine.

The trouble with dual booting comes from splitting a drive into partitions with different OS’s on them sharing the same boot partition. Eventually windows will nuke grub and you will loose the ability to boot linux till you use a live USB to repair through chroot and fixing/installing grub manually or using a grub-repair live USB. Usually only gets complicated if you have luks set up.

I don’t advise dual booting on a single drive. I intentionally buy gaming laptops with dual drive setups and keep the windows drive untouched till the warranty is out. Just in case i have to send it in for repair. Been doing this since 2004 without ever having any bootloader issues that I didn’t cause myself.

Wanted to say thanks, it defiantly pointed be in the right direction!

Sick I’ll give her a whirl.

You could write a simple python script using datetime and pyperclip. Datetime would supply the date format and pyperclip to copy that to your clipboard. You could setup a key binding to call the script then [Ctrl + v] to paste.

I believe all linix distros have python installed OTB.

There are probably a bash solution but my bash is rubbish.

Edit:

The bash solution that has been provided is the best option IMO. I just thought I should provide the code for my solution so you have options. This python script is easily extendable / customizable. All this depends in you installing the python module pyperclip. datetime should be part if the standard python library so you dont have to install it.

installing pyperclip with pip.

pip install pyperclip

The script:

#!/usr/bin/env python3
"""A simple script to copy a formatted datetime string to the users clipboard"""

import datetime
import pyperclip

def clipboard_timestamp(initials) -> None:
    """Function to create a formatted timestamp string to users clipboard.

    Arguments:
       initials: Uses the provided string during formatting of the timestamp."""

    time = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
    pyperclip.copy(f"{initials} {time}")

if __name__ == "__main__":

    clipboard_timestamp('ABC')

The above script also adds the hours minutes and seconds to the timestamp. If not needed remove the %H:%M:%S. Dont forget to edit anything that you want like the 'ABC' near the end.

Save script somewhere. I usually save personal scripts to ~/.local/bin so they are out of the way. I used the name clipboard_timestamp.py Doesn’t really matter as long as you remember the name. Next you have 2 options. You can make the script executable using chmod a+x clipboard_timestamp.py. If you dont want to take this step you will have to tell the shortcut that python is executing the script by prefacing the script’s full path with python like so python ~/.local/bin/clipboard_timestamp.py If you made the script executable you just use ~/.local/bin/clipboard_timestamp.py.

I use KDE but your system should be similar-ish. in your desktop’s setting’s search for keyboard and you should see something that says something like shortcuts. Add New -> Command or Script. Point this to your newly saved python script /.local/bin/clipboard_timestamp.py. Then you choose the keystroke combination.

You might want to file a bug report so they can grab some info from you that could help an updater get pushed sooner and help others.

Very glad you got up and running. Hopefully they will get a better update pushed out soon.

Hay if the restore works might hold off on doing an update for a few days just too see if kubuntu had pushed a bad update. If they did they did they should fix it pretty quickly when they get a bunch of people with broken systems.

I haven’t used timeshift in at least three years so Im going to give you this instead of relying on my possibly faulty memory.

Yes try to do that first. First research how to restore from timeshift backup so you do it properly.

Does ethernet work?

Did you chroot and reupdate? You might want to reuse timeshift to roll back before doing so.

Could also try going back a couple timeshifts ago.

Have you tried making sure network manager is enabled and started?

sudo systemctl enable NetworkManager

sudo systemctl start NetworkManager

From a live USB do you have networking?

I think your best bet is https://xdaforums.com/.

just trying to understand what I did wrong.

You might not have done anything wrong.

There is also the possibility of a bad USB drive or write memory failure. There is lots of things that could go wrong that’s not your fault. Might try a different USB or a different USB port on your machine.

You might want to try zeroing out the USB, if=/dev/zero. Then you might need to make a new partition table. You can use something like gparted. Or https://linuxconfig.org/how-to-manipulate-partition-tables-with-fdisk-cfdisk-and-sfdisk-on-linux

You can try GPT or DOS. I dont think it matters.

Not sure if the ISO will have the partition table so you might want make the new partition table just to be sure the stick defiantly has one. If dd overwrites it from the iso no harm no foul.

Thats all the troubleshooting steps I can think of right now.

Did you make sure that the of is correct? lsblk to make sure.

If your sure it wrote to the right drive i would make sure that you have a good download. Did you run your checksums?

I think fedora works with secureboot but you might want to disable it just to see if that is the issue. I believe you can reenable it after install.

Make sure to go into the bios and boot from external drive/usb.

Out of 15 years of using dd i have never had a problem.

Fair enough!

I very much appreciated the xkcd, gave a good chuckle.
