Comment 6 for bug 1897491

I have encountered this problem in the armhf board too. I employed Xubuntu 20.04 on both RK3399(aarch64) and RK3288(armhf). Then I found that the lightdm-greater cannot work in RK3288. The log is the same as Steve said. I attempted to avoid this problem by logging in automatically. It's a trick to use Xubuntu with a problematic greeter since it still goes to a black screen if I want to change users or reactiong. Do you find any solutions to resolve this problem?
