It doesn't work on my AMD Renoir laptop though.. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1886937 Title: limited hardware support AMD 4700u HP Envy x360 13-ay003nd Status in linux package in Ubuntu: Confirmed Bug description: Suspend/Hibernate: screen goes off, nothing else happens. After user interaction, screen turns on. Login screen is shown. Sometimes screen does not turn on: physical reboot required. kernel upgrade to 5.8rc3 or 5.8rc4 has no effect. Brightness: Adjusting brightness has no effect, nightmode has no effect. Partial solution: kernel upgrade 5.8rc3 or 5.8rc4 solves this partially, brightness can be adjusted and nightmode works But after a reboot brightness is always at max. Also brightness cannot be lowered as much as normally expected. CPU & fan: CPU is always high, 5.8rc3 solves this partially, fan is still always on and quite high (after clean Ubuntu install, nothing configured or installed).
