Turn on bluetooth on login screen in Tumbleweed

After taking a very long break (over a decade) from running openSUSE on my person machine, I finally got Tumbleweed installed on a spare Intel NUC machine. If you’re one of my blog readers, expect to see more contents about SUSE/openSUSE later. Today, I’m going to share how I fix the issue with bluetooth keyboard/mouse not connected to this NUC at the login screen. I can’t remember I needed to do that my main machine running Fedora, but oh well, the fix is simple enough (if you know now). ...

How to Create Exfat Filesystem on Usb

Create a Disk Image With dd Command

Situation: I want to re-use an external drive which already contains some data. So I will create a disk image on an external drive in case I need to copy that image back to the drive in the future.

mkfs.xfs: cannot open /dev/sda1: Device or resource busy

I’m trying to create an XFS filestem on a used disk, and got into a problem. Here is the error message: # mkfs.xfs /dev/sda1 mkfs.xfs: cannot open /dev/sda1: Device or resource busy So, let’s see if I can fix it. (Spoiler alert: I think I can, even though it’s not yet done at the time of this writing.) Let’s check the partitions of /dev/sda: # parted /dev/sda print Model: ATA ST1000LM014-1EJ1 (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 512GB 512GB ntfs 1 So, there is a partition (/dev/sda1) with 512GB in size, and its filesystem is ntfs. I was pretty sure that I had selected xfs as the filesystem. ...

Using xclip to copy terminal content to clipboard

It’s quite annoying when I know the command I can use to copy the content on a terminal to clipboard. I know, I can run man xclip, but I think it’s still easier for me to visit this page and see how to do it. For example, I want to copy the content of my ssh keypair, ed2559.pub, to clipboard, and here how it can be done: ➜ xclip -sel clip < ~/.ssh/id_ed25519.pub Or: ...
