Review on Renewed Lenovo Legion 5 Gaming Laptop: 15.6" 144Hz, AMD Ryzen 7-4800H, 16GB RAM, 512GB SSD, RTX 2060 6GB, Phantom Black by Hideo ᠌

I’ll write more about installing Linux, in case it helps someone and you don’t have to sit for several nights with red eyes. The main problem is the non-working touchpad. The problem is discussed, for example, on launchpad bug 1887190. Answer 254 helped me, which describes how to patch the kernel. It seems that you need to rebuild the kernel no younger than version 5.8. I collected 5.92022. The touchpad worked. Accordingly, if you do not sign the kernel, then you need to disable secure boot in the BIOS. The second major problem is installing the video card driver (out of the blue). In the bios, you need to set the forced use of a discrete graphics card. Fresh versions of drivers do not get up (neither from the repositories, nor from the nvidia website. I only installed the driver version 440 from the ppa with drivers, which is easily googled. But even with this driver, everything is fun. The screen backlight is not adjustable from the keyboard, and after waking up from sleep, the screen loses some of the colors (everything becomes high-contrast). You can deal with highlighting in many ways, passing parameters to the kernel, configuring xorg. Conf, and so on. But none of this helped me. Only the brightness controller script works, which was posted on the github by the user momen84. With the violation of colors after waking up, the situation is still incomprehensible. It is recommended to pass the parameter to the vga kernel equal to 0 (in the hornbeam settings). It seems that the truth has become better, but sometimes the laptop has to be put to sleep again, and only after the second awakening do the colors return to normal. Despite all this circus, I am very pleased with the laptop, it is a pleasure to work with it))
