Comment # 19 on bug 1195094 from Stefan Dirsch

Just found that in the latest release of nvidia driver

diff -u NVIDIA-Linux-x86_64-525.089.02/
NVIDIA-Linux-x86_64-525.105.17/NVIDIA_Changelog
[...]
 ======== Release 470 Entries ========

+    * Fixed a bug that could cause fullscreen PRIME Render Offload
+      applications and/or X to crash when an NVIDIA GPU is driving
+      multiple displays with Reverse PRIME.
+
+    * Added support for console restoration when using simpledrm.
+

Not sure what this means ... and it would be only relevant for the 470.xx
legacy driver, i.e. not for the current driver 525.xx ?!?
