Dear forum users,
I carefully read each post vs my vmware folder shareing problem under Solus xfce OS and finally I get SHAREFOLDER works as describes the follows:
It is confirmed that after install open-vm-tools, the daemon as service would be start with the system startup, but no shared folder though I've setup a win10 folder namely QFTPsvrRoot at vmware configuration tab. At the /usr/bin of Solus, I found a routine called vmware-hgfsclients and executed with a result of the shared folder name QFTPsvrRoot. At the stage, I found Solus already got Win10 folder, and what I have to do is to make it accessable at the Solus. So, try another routine at /usr/bin namely vmhgfs-fuse by typing vmhgfs-fuse --help, and then a short help context appears. I did accordinly as "sudo -S vmhgfs-fuse .host:/QFTPsvrRoot /mnt/hgfs -o allow_other -o nonempty -o auto_unmount" provided a hgfs folder hgfs was created under /mnt. After this, QFTPsvrRoot folder is ready at /mnt/hgfs. So, I modified the statement line as "echo [root passwd] | sudo -S vmhgfs-fuse .host:/QFTPsvrRoot /mnt/hgfs -o allow_other -o nonempty -o auto_unmount".
Finally, add below one line to the /etc/fstab file
.host:/QFTPsvrRoot /mnt/hgfs fuse.vmhgfs-fuse allow_other,defaults 0 0
Each time the system startup, the shared folder is automatically mounted, and so it works.
As systemd is a complete new kernel module other than sysV, vmware tools is no longer support for the guest OS, and instead open-vm-tools is suggested by vmware. Actually, one may just install xf86-video-vmware package in the guest OS terminal, the Solus screen will then works fine.
In summary:
Install open-vm-tools, then xf86-video-vmware, by which my Solus xfce and plasma works fine now.
Thanks to all for helps!
