I pressed Ctrl+L to lock the screen of my PC while it was upgrading Ubuntu from 14.04 to 16.04. The problem is that the PC now does not react to any interrupt from the keyboard or mouse(and obviously now I have a blocked monitor). How can I fix that?

I tried setting up Nannou following the instructions here.
I am running Debian Buster on a MacBook with an NVIDIA graphics card (GK107M [GeForce GT 750M Mac Edition]).
I tried running the example and get the error
thread 'main' panicked at 'could not build default app window: NoAvailableAdapter'
It seems this is an error when Nannou tries to open a window -- something about its communication with the window manager (Gnome on xOrg), or something about vulcan-tools.
Any ideas for how to debug this?
The issue is that I was using the open-source Nouveau driver for my graphics card (the default on Debian) which does not currently support Vulkan, which is required for Nannou.
By installing the proprietary nvidia graphics driver, the problem was resolved.
I was able to install the nvidia driver by running
apt install nvidia-driver,
and then rebooting my computer,
as described in this tutorial https://linuxconfig.org/how-to-install-nvidia-driver-on-debian-10-buster-linux
Now nannou works :)
I recently bought the HP Specter x360 and I installed ubuntu 20.04LTS. However, until now I have not enabled the Bluetooth on the laptop, I tried a lot but with no results. Please, there is anything to do in order to enable Bluetooth?
I used GRUB settings at startup:
Restarted Ubuntu and pressed ESC to load “Advanced options for Ubuntu"
Then selected option to enable network
Then option to repair broken packages
Finally "resume reboot".
Bluetooth service was back.

This has been answered before.
Go to "Software and Updates" > "Additional Drivers", and change to the proprietary driver for your card. Reboot.
My Flame phone currently runs Firefox OS 1.3 and I am trying to flash to version 2.0. After connecting the device to my computer I run 'adb devices' in the terminal and it successfully recognizes my phone. But when I try to run the script with './flash.sh' my phone reboots as it should but then gets stuck on the splash screen that reads "ThunderSoft" and the terminal simply sits there with the following message:
Flash nCPU...
< waiting for device >
I'm doing this on Ubuntu 14.04. I have remote debugging enabled as instructed. Any suggestions?
