  • @6R1MR34P3R Some of the LILYGO devices are great for use straight out of the box. I have a T-Echo as my portable device, the T-Deck Plus is also an option if you want something completely stand-alone rather than controlled over Bluetooth or USB. Note that the 868MHz band is more widely used due to congestion on 433MHz, (915MHz is for the Americas and isn’t legal here)








  • @Pogogunner At least on Debian based distros, it’s all part of the driver installation.

    As for how it works at the hardware/kernel level the iGPU take some of system RAM to use as VRAM, so all the kernel has to do is give the dGPU a DMA buffer into that. The final piece is for the iGPU driver to send a synchronisation signal to the dGPU when it’s ready to receive the (partial-)frame.
