I don't know if this will help find the solution to this problem, but for what it's worth, here's a solution that worked in my instance & I would very much like to know why it worked. System; Lenovo V155-15API (V155 Series) Processor; AMD Ryzen 5 3500U Graphics adapter; AMD Radeon RX Vega 8 Memory; 12288 MB (Windows partition)
Dual booting Windows 10 & Ubuntu 19.10 (Ubuntu being main OS on separate partition) Problem that developed in Ubuntu, hibernate/sleep/resume (including lid close) not working correctly consistently, requiring a power off reboot. After failing to find an answer to the problem in Linux, I eventually booted into Windows to find the problem even worse there, no hibernate/sleep/resume at all, a power off reboot the only option. Solution (So far); I downloaded the AMD Driver Auto-detect tool & let it install the drivers it detected as needed or needing updating. After this I rebooted into Windows & found hibernate/sleep/resume to be working perfectly. Thinking this to be a Windows only fix, I rebooted into Ubuntu with the intention of finding drivers suitable for fixing the problem in Linux, but before doing so, found to my surprise that hibernate/sleep/resume were now working perfectly in Ubuntu as well. Is these drivers somehow being shared via the EFI partition? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1849084 Title: Freeze on system-resume caused by kwin and amdgpu driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kwin/+bug/1849084/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
