For all who used the workaround #61: The current update xserver-xorg- video-amdgpu-hwe-18.04:amd64 19.0.1-1ubuntu1~18.04.1 19.1.0-1~18.04.1 overwrites the file /usr/lib/xorg/modules/drivers/amdgpu_drv.so (file date May 21 09:16) and the bug returns again.
It is one step forward one step back ... Hence either apply the workaround #61 again or step back to my suggested workaround #54. -- 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/1849084 Title: Freeze on system-resume caused by kwin and amdgpu driver Status in kwin package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Status in plasma-desktop package in Ubuntu: Confirmed Status in xserver-xorg-video-amdgpu package in Ubuntu: Confirmed Bug description: This is a well investigated bug by me. Problem: a black screen freeze occurs by suspend-resume process Ubuntu version: Kubuntu 19.10 default plasma, or the backported 5.17 Kernel version: default 5.3.10 or the mainline 5.4.0rc3 xserver-xorg-video-amdgpu: 19.* or the newest from git, the 18.0.1-1 works well This freeze can be reproduced only if opengl 2.0 or 3.1 compositor is enabled in Plasma settings. Xrender is OK however I don't like screen tearing. On Ubuntu 19.10 Gnome desktop (X based) this doesn't occur even if the Gnome's compositor is enabled. (I don't know what is the default one there but I haven't disabled it) I think this is a Kwin / amdgpu driver related bug because of the differentiation. These can be fixed even in Kwin/opengl compositor not just in the amdgpu driver or in kernel. One possible solution: disable opengl compositor by suspend and re- enable it after login. Use fe.: Xrender before login / before the system restored from suspend. For Ubuntu's maintainers: Couldn't be this problem solved by a downstream solution? Maybe a proper script could be enough by resume and by suspend. There are a lot of bugs like this reported in freedesktop bugreport and the developers haven't got enough time for fix them fast enough.
