Thanks for the info? I had tried rebuilding with hostonly, but still
was same size, so it must be defaulting to sloppy on one machine?
Both are same Dell Lattitude 5580, so assume they have the same
video cards.
One with big kernels shows lspci
01:00.0 3D controller: NVIDIA Corporation GM107 [GeForce
940MX] (rev a2)
00:02.0 VGA compatible controller: Intel Corporation HD Graphics
630 (rev 04)
Actually, just checked, and small img files only shows
00:02.0 VGA compatible controller: Intel Corporation HD Graphics
620 (rev 02)
Seems will have to do more checking.
Thanks again.
