@Juanito: Thank you very much! I confirm that in both TC12 (32 and 64 bits) the Xorg is running OK.
FYI: in TC12-x86, Wayland was not updated. But it is excellent for me that Xorg does not depend on it.
X.Org X Server 1.20.6
X Protocol Version 11, Revision 0
[ 185.644] Build Operating System: Linux 4.19.10-tinycore i486
[ 185.644] Current Operating System: Linux box 5.10.3-tinycore #2021 SMP Mon Dec 28 16:16:18 UTC 2020 i686
X.Org X Server 1.20.11
X Protocol Version 11, Revision 0
[ 25.169] Build Operating System: Linux 5.10.3-tinycore i686
Also Xorg is now compiled for i686. Good for me, I do not have functional physical i486 neither i586. Even my Dell-Mini10 (from 2008) has i686 CPU (as Intel Atom N270). But qemu 3.1 start with CPU i486. Not big problem to change to -cpu=max, -machine=q35 etc.
But does this mean that the new minimum CPU target for TC12+ will be i686 ?
