I previously wrote an article about taking screenshots in the wayland environment and then using ksnip to modify the pictures (http://mephisto.cc/tech/wayland-screenshot/). I recently discovered that after modifying the pictures, in some cases the pictures cannot be copied. , I still can’t find the pattern that triggers the bug🤷‍♂️

Common display managers (or login managers) include LightDM, GDM, Ly, etc. Most of them are written in C, and often only support GUI or command line interface. greetd is written in rust and supports command line and a graphical interface (greeter).

The screenshot function is used in many scenarios in daily work. When you want to explain a certain problem to your partner, a picture is worth a thousand words. The so-called picture has the truth. The screenshot is usually modified under the comment, and the red box in the key place , operation steps, arrow guidance and so on.

When I was writing some interesting functions of Firefox yesterday, I needed to demonstrate some ui operation steps. At this time, the screenshots are not clear enough to record the process. I think that there are often some gif pictures on Github to demonstrate the operation steps. Use the command line to combine two pictures It is also possible to produce a gif image, which is a little troublesome. In this scenario, it is an ideal way to record the screen operation steps and then generate a gif image. Of course, it is also possible to embed a video on the website, but many platforms do not support video Upload, for simple web tutorials, pictures are more suitable.

Daily Toolset

Recently working with labwc, I gradually found some small problems. I will record them here for the convenience of future generations.

wofi can be used not only as a launcher, but also as a display menu (menu). This article introduces these two usage modes. I am very satisfied with the overall experience.

If you are tired of monolithic desktop environments such as Gnome and KDE, and don't want to toss tiling Wayland compositors such as sway, you can try labwc stacking windows (window-stacking Wayland compositor).

The application launcher (application launcher) is usually used to quickly locate and start other programs in the computer. For example, Albert Launcher and Synapse in Linux, Alfred in macOS, etc. After pressing the Super shortcut key in the Gnome environment, it is also Almost functional.

Recently, the company needs an IT asset management system. Snipe it is selected among the three open source snipe it, glpi, and ralph. Might try it later.
