Want to work differently with a sub-display during pc game
I want to do notes or research or other things while playing PC games. 2019/08/28 Add some method about virtualization History When I captured Splatoon, I noticed that it’s convenient that I can serch information while loading. In addition, specified for foreign game, I want to search dictionary. All pc games that I currently have will stop when the screen is inactive, so I can’t do this. Even if there are two screens with great pains, it does not make much sense. -
Enable Ubuntu 19.04 Server to start over LAN (Wake-on-LAN)
History
I decided to suspend the file server during the daytime on weekdays to save electricity, so I have to manually cancel the suspend on a public holiday weekday. This itself is unavoidable, but at least, I want to be able to turn on remotely via LAN from the main machine rather than the power button . So I try the fanction called Wake-on-LAN.

'Turn off returning from suspend by the mouse'
There is a strange phenomenon that the main PC returns from the suspend without automatically. I was observing it, and it seemed to wake when the refrigerator groaned.

So disable to return by mouse.

In my case,I use Windows10 reluctantly for only PC games, so I want to do something as much as possible on Linux,
but it would be a rare case. -
Install ZFS to Ubuntu Server 19.04 and build RAID1
Circumstance
Less than half a year to move the PC to homebrew NAS. Because of lack of budget, My NAS has single HDD,
but now, I want to buy additional HDD and build mirroring to save my dataAt first, i was going to build a raid1 with ext4 and motherboard function, but after research, I decided to install a file system called ZFS. The reasons are following,
- The file system itself supports RAID
- Many useful functions such as transparent compression and snapshots
- It eats cpu and memory, On the other hand, I can think that make good use of my NAS’s specs.
