Ubuntu uses GNOME on Wayland by default. RustDesk works well once the desktop session is running, but unattended access can become awkward around the graphical login screen. On my Ubuntu 26.04 system, the practical solution was to use an X11-based LightDM login screen while keeping the normal Ubuntu GNOME Wayland desktop after login: LightDM + Slick Greeter + X11 ↓ Ubuntu + GNOME + Wayland This gives RustDesk access to the login screen without replacing the everyday Ubuntu desktop.
Completely Remove Snap from Ubuntu
Snap ships enabled by default on recent Ubuntu releases. It offers a distribution-independent application format, automatic updates, dependency isolation, and optional sandboxing. Those features are useful, but not every system needs a second package-management stack alongside APT. Desktop users may prefer traditional Debian packages, and administrators of minimal servers may want fewer background services with all software under APT-based change control. This guide covers how to: Remove all installed Snap packages Purge the snapd service and its remaining data Prevent APT from reinstalling snapd Restore Snap later if needed The procedure targets recent Ubuntu Desktop and Server releases, including 22.04, 24.04, and 26.04. Package selections may differ between releases.
Enable Microsoft Remote Desktop (RDP) on Linux
Gnome 42 has a fantastic new feature that allows Linux users to share their desktops with Microsoft’s Remote Desktop Protocol remotely, namely GNOME remote desktop. In this tutorial, we’ll show you how you can use this great new feature. Without this feature, an alternative solution is xrdp. However, xrdp cannot provide a consistent desktop environment as used in current Linux. Enable Automatic Login and Disable Screen Lock For the remote desktop to work on GNOME, we have to enable automatic login and disable automatic screen lock. Otherwise, it is unable to connect to the Linux PC remotely from Windows 10/11 using the Remote Desktop Connection app.

Use Internet Explorer in Windows 11
Background With Windows 11, Microsoft has removed several outdated apps and features, including the long-hated Internet Explorer. However, some proprietary apps and legacy sites still require Internet Explorer functionality to run. Several posts suggest using the IE mode in Microsoft Edge. However, it does not work for some websites: a few government service portals, for instance, still fail to load correctly in Edge’s IE mode. Solution Step 1. Create a VB script, named ie.vbs with the following content.
Install QQ/TIM in Linux with Wine
Note: This post describes a Wine-based workaround from 2017. Tencent now ships an official native Linux client for QQ, rebuilt on the NT architecture and available as deb, rpm, and AppImage packages for both x86-64 and ARM. You should grab the native build from im.qq.com/linuxqq instead; the Wine instructions below are kept only for historical reference. This tutorial introduces how to install QQ/TIM in Linux with Wine, which had been tested on ArchLinux with Wine 2.4.
Setup Raspbian on Raspberry Pi
This post explains how to install Raspberry Pi OS and set up a Raspberry Pi from scratch. You will need another computer with an SD (or MicroSD) card reader to write the image. Note: This post has been updated for Raspberry Pi OS and Raspberry Pi Imager. Raspbian was renamed Raspberry Pi OS in 2020, and the old “download a .zip, unzip the .img, then flash it with Win32 Disk Imager” routine has been replaced by the official Raspberry Pi Imager, which downloads and writes the image in one step and can pre-configure SSH, Wi-Fi, and your user account before the first boot.
Building and Installing HHVM on CentOS 7
What’s HHVM? HHVM is an open-source virtual machine designed for executing programs written in Hack and PHP. Instead of interpreting PHP directly, it uses a just-in-time (JIT) compiler to reach much higher throughput while staying compatible with existing PHP code. Facebook, which created HHVM, reported roughly a 9x gain in web request throughput and a 5x drop in memory use over the old PHP 5.2 + APC engine, and back in 2015 HHVM could run most of the popular PHP frameworks out of the box.
