Hey,
Was able to bring up a pretty smooth armbian installation for a lightweight desktop. Tips for others:
Underclock Memory for stability
cat /etc/rc.local
#!/bin/sh
echo 1560000000 > /sys/devices/platform/dmc/devfreq/dmc/max_freq
For bluetooth blacklist the following modules:
blacklist pgdrv
blacklist btusb
blacklist btrtl
blacklist btbcm
blacklist btintel
NVME boot, use armbian-installer, but I had to manually change the firmware to this one: https://wiki.radxa.com/Rock5/install/spi#Simple_method to get NVME boot to work
For GPU acceleration install panfrost. (See rock5b ambian page)
To get my widescreen monitor to work I needed to switch to the daily kernel.
The best browser experience seems to be the brave arm64 build.
One thing that is annoying is the mouse pointer is constantly flickering while using brave. Does anyone know a solution to this?
