Unfortunately, you don't have a GPU with drm drivers, but are using a
drm layer for "dumb framebuffers" (simpledrm). This replaced fbdev
drivers in Fedora 36 (see
https://fedoraproject.org/wiki/Changes/ReplaceFbdevDrivers).
From what I've read, it depends on graphics config in the BIOS, and
supports whatever mode is set up on boot, or some VESA layer.
Have you ever gone into the BIOS settings on the laptop? If not,
resetting might help.

installed drm_info and got this:
