I love gkrellm for monitoring my machines. And I've been using the same config files for 20 years now. I'm so happy it's still in the default repositories everywhere! So. Recently I added a new remote gkrellmd machine, and got the time shown as AM/PM. :? Here are the format strings for each layout: ...

Here's a rough example for a non-blocking IP (TCP) port listening for incoming connections, without blocking the video playback: (OS is Xubuntu 20.04, MPV v0.32.0) -- Import LuaSocket library local socket = require("socket") print("Socket.") -- Create a TCP socket and bind it to ...

I've filed a bug report on this one, since I find it odd: https://bugs.launchpad.net/ubuntu/+source/mousepad/+bug/2047968 In 22.04, several things have "regressed" for my flavor of using Xubuntu. Keyboard shortcuts not working (as expected by me, a long term user): * `Super + Right, Super ...

On a minimal install of Xubuntu 22.04 (jammy), you don't get the option to browse network shares (samba/smb/cifs) in Thunar out-of-the-box. You need to install the following packages, then log-out-back-in and it just works :D $ sudo apt install gvfs-backends smbclient Thanks: https://askubuntu.com/q...

When booting an Ubuntu installer ISO (eg from a USB-stick) on an EFI-capable machine, it may sometimes happen that it still boots the legacy-BIOS version. I finally found out *why* this happens - and how to change that. When you select the boot-device in the BIOS, make sure it boots the medium (USB-...

Running Xubuntu 20.04 with XFCE 4.14 on a 2k display. Here's what and how I've configured to make it look and feel fine: hidpi_xfce4-screenshot.png I'm pretty sure I've not configured my setup completely right for the first time. So I must admit I'm surprised that I don't want that 2k display on my ...

I'm using a 2k BenQ display on XFCE4 (Xubuntu 20.04), and it works, but it's still a bit of a bumpy ride. I know there's been some updates regarding HiDPI since 22.04, due to the more recent xfce4 packages, but it still feels too scattered too remember - *where* to find and change which value to get...

This is merely a short writedown of something I always forget for years now: (Should work on most GNU/Linux distros, but I've usually used it on Debian-flavored ones (eg Xubuntu)) Assuming the to-be-checked storage media (eg USB-Stick, HDD, etc) has the physical device name of "/dev/sdX" (...
