Hi,
I am sorry for the confusion. There is no bug and I just wanted others to know that if NuTxY is installed in xfs file system, then other Linux distributions will not recognize NyTyX in the same system. However, if ext4 file system, which is now normal for most of the distributions, is used, there is no such problem.
Hope it is clear now. Apologies for wasting your time.
BTW, I have installed Gnome, Mate, KDE5, LXDE and XFCE4 in NyTyX with ease and am studying each so that I may try the same with LFS/BLFS.
Regards.
VSN
