Although I personally think Clutter's dependency on the graphics card driver and general graphics card driver VESA are not very well supported, however, clutter does provide brilliant dynamic effects and is compatible with GTK, QT, and so on. This prevents us from considering the impact on the system too much for Clutter select

Game control bar support. A great game controller API is built in the latest Linux kernel. I plan to integrate this support into the SDL event model, which allows any event filtering, callback, and asynchronous event dispatch. Garret banuk has compiled the initial implementation, which will be added to the latest SDL Development Branch.

VGA
VGA(Video graphics Array) Is a computer display standard proposed by IBM in 1987 using analog signals, which is outdated in today's PC market. Even so, VGA is a low standard supported by the most manufacturers, and personal computers must support VGA before loading their own unique drivers. For example, the boot screen of Microsoft Windows products still uses the VGA display mode, which also shows that the resolution and the number of colors are insufficient.
VGA is often used directly to re

The result was too new and not supported. Install fedoraIf the problem is displayed during the process of 10, it means it is not applicable to the graphics card driver. For example, if the old graphics card and the new graphics card are too old, you can press the ta

Many display cards are constantly introducing upgraded drivers to modify errors in the original program, adapt to new specifications, and improve the performance of the display card. For users, software performance improvement practices are deeply rooted in the hearts of the people.
