All Questions(ubuntu)

I've installed Ubuntu 24.04.2 LTS on a new PC and I'm facing an issue with the Bluetooth adapter. The system detects it, and it appears powered on, but it cannot discover any nearby Bluetooth devices.

Here's the relevant system and diagnostic information:

Operating System: Ubuntu 24.04.2 LTS Kernel Version: 6.11.0-24-generic Bluetooth Adapter: IMC Networks Bluetooth Radio (USB ID 13d3:3600)

bluetoothctl scan on behavior: When I run scan on in bluetoothctl, the command executes and starts discovery, but it does not list any nearby Bluetooth devices.

Can anyone help me identify which driver I need to install? This is on an Asus ROG700 prebuilt PC.

Recently upgraded from 20.04 to 22.04 and firefox lost it's window decorations (that is, there's no title bar at all, no corner handles, I can't move or resize it). I've found a bunch of similar posts that all refer to either using Gnome settings (nope, I'm running fluxbox), re-enabling the title bar from the "customize toolbar" menu (there's no tick box that would do that), others suggest fiddling with MOZ_GTK_TITLEBAR_DECORATION and/or GTK_CSD, neither of which seem to impact the behaviour.

Not that I think it matters, the hardware is an older Dell mini-tower with an i7-6700, on-board Intel graphics HD Graphics 530, 64G RAM.

Other things that are completely borked:

• it doesn't respond to keyboard shortcuts.
• pull-downs activated with the mouse follow the focus to other desktops

Does anyone here have other ideas of how to get the window decorations back?

I installed Ubuntu 25.04 a few days ago , after last update a new ghost icon with the name "Fortune" has appeared on app launcher screen , this Fortune does not exists in app center and not installed and I am not able to remove it'

I want to encrypt the root filesystem on an Ubuntu Server 24.04 installation on my Raspberry Pi 5. I don't have any cables for the weird microHDMI connector they use on the new Pis, so it would be nice to do this headless. Root filesystem is located on an SD card, and I would like to use key files for encryption instead of passwords. There is this answer and this guide, but nothing about a way to do this headless, unfortunately.

I'm setting up my home cloud server, to test everything before buying a proper multi bay hard disk case and some disks to build a RAID I want to use a cheap usb 3.0 to sata adapter, and a wd purple 2tb disk that I have. The disk is working on my main pc plugging it into the sata port, but if I plug the usb adapter into a usb 3.0 port the disk is not seen with lsblk, then if I plug it into an usb 2.0 port it is detected correctly. The same on my windows pc. The adapter has 12v input as the disk is 3.5" the sys is running latest ubuntu server. Anyone that can help?
