Bug Nautilus slow SMB Performance gvfs-smb
If you use Samba as File Share (NAS) Samba mounts often hang by listing huge amount files like Photos. Known Problem is the gfvs-backend is hanging up on switching between smb protocol (smb1-2-3) versions! Faster is to use the cifs Kernel mount without the gnome-backend communication open Terminal enter: id myusername mkdir /home/myusername/nas/ with known id do: Workaround edit /etc/fstab insert: sudo nano /etc/fstab insert at the end !! //192.168.1XX.XXX/nas /home/myusername/nas cifs file_mode=0777,dir_mode=0777,username=myusername,password=XXXX,domain=home.local,uid=10XX 0 0 Now over 50MB’s per second should by possible over gigabit cable. If not needed disable Samba Logging!

Android OS vs Linux Widevine Support on ARM64
If you use a odroid device like my odroid n2 you should know that the OFTEN needed DRM Browser Plugin “Widevine” in NOT available by default for ARM64.

Its much simpler to setup Android and use the Apps like Amazon Video or else.. Google does NOT offer a Widevine to ARM64 CPU Support by default. Try x86 TV Sticks or Boxes like the intel tv stick if […]
