With a fresh installation of Fedora 32 on a ThinkPad X1 Extreme, my screen flickers occasionally. The flickering to and from a black screen happens every couple of minutes, and takes a fraction of a second.
On Windows and Ubuntu 20.04, this does not happen, and so this appears to be a Fedora-specific issue.
The flickering happens regardless of whether the nouveau or proprietary NVIDIA drivers are used, and also regardless of whether Xorg or Wayland is used.
Solutions and/or ideas for things to try would be very welcome.
