How does this differ from the "VESA" linux driver?
- ComputerGuru 6y agoThey start at the same place but it works better (more resolutions, greater hardware support, fewer bugs, etc), includes features that are outside the scope of the driver itself in the Linux design (EDID querying and matching for dynamic resolution and refresh rate detection), performs much better when doing software-accelerated operations, has driver/abstraction-level DPI scaling, and is compatible with all DE/software that doesn’t try to directly use OpenGL. Mostly it’s just that the video abstraction on Linux is driver-dependent (eg access to video device/fb is dependent on choice of driver) functioning at a lower level than the Windows equivalent. I’m not sure if it’s true but I hear Wayland is throwing away all support for non-drm framebuffers?
