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.
