Bug ID: 205169 Summary: AMDGPU driver with Navi card hangs Xorg in fullscreen only. Product: Drivers Version: 2.5 Kernel Version: 5.4.0-rc2 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: drjoms@gmail.com Regression: No
I have another problem logged with Navi + AMDGPU drivers. It's triggered independently and reliable. https://bugzilla.kernel.org/show_bug.cgi?id=204725
With that said, starting strictly and specifically with kernel version 5.4.0* I have new problem.
I successfully load into Xorg. I can start OpenGL and Vulkan games in non full screen. But once I start them - input devices hang, screen freezes. Machine is responsive over SSH/ethernet. I can raise skinny elephants.
I tried opening a few games in non full screen mode and in full screen mode. And i reliably hit bug everytime anything with OpenGL goes full screen on native resolution of the screen.
I noticed, issue is less likely to happen if program goes full screen in non native resolution.
I will attach details in files for DMESG, lsmod and some other things directly as message, if they are short enough.
