[00:27] <MatinalSun> tomreyn The kernel is 4.4.194 in the SDK offered by Rockchip. It is customized for aarch64 RK3399.
[00:49] <tomreyn> MatinalSun: hmm, okay, that's not a kernel we support here, you'd need to use an ubuntu kernel and unmodified OS installation so we could help out.
[00:53] <MatinalSun> tomreyn But where can I find an image that could run on the RK3399 board？
[00:54] <MatinalSun> I found an issue on XFCE forum same as my problem. this is the link :

[00:56] <tomreyn> MatinalSun: i assume there is no official support for this SBC
[00:56] <tomreyn> i.e. you'd need to get help from the hardware vendor
[00:59] <MatinalSun> And I test lubuntu and normal ubuntu yesterday. It all can use double-click to open the files.
[00:59] <MatinalSun> hmm,RK doesn't support ubuntu due to copyright issue. I am going to contrast the difference between these rootfs.
[01:37] <MatinalSun> Double-click in Xubuntu18.04 also work fine
