Cannot enable 1GB pages on Ubuntu 20.04
Hello,

I tried all the usual stuff, ran xmrig with sudo, tried the enable 1GB pages shell script, nothing really works. I can't seem to enable 1GB pages. 

```
:~/Desktop$ sudo ./1gb.sh 
vm.nr_hugepages = 256
1GB pages successfully enabled

:~/Desktop$ cat /etc/sysctl.conf | grep "huge"
vm.nr_hugepages=1280


```

Ran the miner as sudo and still nothing.
