Review on 🎮 Lenovo Legion 5 Gaming Laptop with AMD Ryzen 7, 16GB RAM, 512GB SSD, and NVIDIA GTX 1660Ti by John May

Use case - AI and GPU accelerated machine learning for Windows and Linux. Memory upgrade from 16GB to 64GB with Crucial Dual SODIMM 64GB Kit, model CT2K32G4SFD832A. SSD replaced with Dual ADATA XPG SX8200 Pro 1TB Dual Boot (Fn F10) Windows and Linux. Both hardware upgrades work great with no hiccups. Currently installing Ubuntu 20.04 (installing in safe graphics mode). No other distro worked. I've tried Debian Buster 10.4 and Proxmox with no success. I think they fail due to graphics incompatibility. The current version of Ubuntu 20.04 (Kernel 5.4) has some problems with the device. Touchpad and brightness do not work. The community was actively involved in finding the issue and suggesting a workaround. I used the gist of jbuncle/build-patched-kernel.sh to rebuild the kernel to version 5.9 which included patches for the touchpad. It took 45m but he built 5.9 and fixed the touchpad and brightness. Excellent work! In general, there are some inconveniences with Linux, but they don't stop the show. I am very satisfied with the background noise in sleep mode. The 144Hz display is really good and bright enough for anything but sunny days outside. Update October 28, 2020: When using Ubuntu 20.04 (Kernel 5.9), the Bluetooth driver disconnects about every 10 minutes. The workaround is to pair the device again or just use wired headphones. Update from October 29, 2020: Attention! CrystalDiskInfo reports that the temperature of the second NVME SSD reaches 74°C during CrystalDiskMark writes. Be sure to use a good heatsink and make sure it works. My drive (ADATA XPG SX8200 Pro) uses a manufacturer supplied heatsink. Drives cool down after completing the flash write tests. When using CrystalDiskInfo, use F5 to update temporary files. Update 12/7/2020: Linux does not display on HDMI, although external monitor is recognized. The Windows output works as expected. There must be a problem with the NVidia driver since v455. v440 seems to turn on the backlight but there is no image either. This is indeed an indicator as I was hoping to use gpu-pass for the client VM. Update December 11, 2020: Tried several updated Linux distributions. They can get close to almost anything that works, but none of them are perfect yet. I'm sticking with Ubuntu for now, but look forward to the HDMI output being fixed. HDMI is being worked on for some other distros like Manjaro and OpenSuse, so it might come to Ubuntu soon too.
