I just installed Chimera RC on a Gigabyte Z590 machine (incidentally
it looks like I could autoconfigure wireless with providing firmware).
When I installed xorg and fluxobox, the display was low resolution.
Apparently it is a low resolution default. lxrandr offers no other
accessible resolution.

I here paste the return of inxi on my current machine and then on the
installation of Chimaera. Neighter machine has a v ideo card. I'm not
sure that to make of this.

The old machine with good resolution

   Graphics:
     Device-1: Intel HD Graphics 630 vendor: Gigabyte driver: i915 v: kernel
     bus ID: 00:02.0 chip ID: 8086:5912
     Display: server: X.Org 1.20.4 driver: loaded: modesetting unloaded: fbdev
     failed: vesa resolution: 1920x1080~60Hz s-dpi: 96
     OpenGL: renderer: Mesa DRI Intel HD Graphics 630 (Kaby Lake GT2)
     v: 4.5 Mesa 18.3.6 compat-v: 3.0 direct render: Yes

On new machine with poor revoltuion

  Graphics:
    Device-l: Intel vendor: Gigabyte driver: N/A bus ID 00:02.0
    chip ID: 8886:4c8a
    Display: serve: X.Org 1.20.11 drive: loaded: vesa
    unloaded: fbdev,modesetting resolution: 1024x768-76Hz s-dpi: 96
    OpenGL:  renderer: llvmpipe (LLM 11.0.1 256 b its) v: 4.5 Mesa 20.3.5
    compat-w 3.1 direct render: Yes

Help intrpreting this would be much appreciated.
