Ubuntu on Asus ROG Zephyrus G14 2021 (Setup guide)

Here is a way to do a robust install of Ubuntu (+ optional Windows 11 dual boot and LUKS encryption) on an Asus laptop, with minimal usable hardware support, without a significant amount of tinkering that may break in future or require frequent technical attention.

In summary, the key thing is to have an up to date kernel, which usually means disabling secure-boot and installing the latest stable (6.0+) using mainline or xanmod, and as well as making sure the latest nvidia driver and dkms is installed.

Specs:

• Model Asus G14 2021 (GA401QC)
• AMD R7 5800 8 core 16 thread (onboard Radeon graphics)
• NVIDIA RTX 3050 4GB (60W +15W boost)

Setting up RetroArch on a Raspberry Pi

I just put the finishing touches on my Raspberry Pi 3 emulation machine running RetroArch. I was not a huge fan of RetroPie due to the reliance on Emulation Station - more moving parts meant that there were more things that could potentially break. I just wanted something that would run raw RetroArch, no frills.

This tutorial is mostly recreated from memory and was most recently tested with a Raspberry Pi 3 running Raspbian Stretch and RetroArch 1.7.7. If there is a mistake or a broken link, PLEASE message me and I will fix it.

Step 1: Install Raspbian

I used Raspbian Stretch Lite from this page. Write the image to your SD card using something like Win32 Disk Imager, or if you're using OSX/Linux follow a tutorial on how to write the image using dd.

How to make Windows 7 USB flash install media from Linux?

StackOverflow

• Install ms-sys - if it is not in your repositories, get it here. Or alternatively, make sure lilo is installed (but do not run the liloconfig step on your local box if e.g. Grub is installed there!)
• Check what device your USB media is assigned - here we will assume it is /dev/sdb. Delete all partitions, create a new one taking up all the space, set type to NTFS (7), and remember to set it bootable:

# cfdisk /dev/sdb
or fdisk /dev/sdb (partition type 7, and bootable flag)

What is this all about?

This tutorial will turn your Raspberry PI into a simple Bluetooth audio receiver, which plays music through connected speakers. It's like a regular car audio system, but it can be used anywhere and it's a good value.

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

# Backup
docker exec CONTAINER /usr/bin/mysqldump -u root --password=root DATABASE > backup.sql

# Restore
cat backup.sql | docker exec -i CONTAINER /usr/bin/mysql -u root --password=root DATABASE
