For us (mips port), it is a long history of problem. The problem is that: the older version of GNOME, or Mate, can work with vesa driver, while current GNOME cannot. Without amd/ati non-free firmware, radeon/amdgpu cannot work at all. So on mips platform with AMDGPU (aka, Loongson-3), it has nothing on display at all, even console. The reason is that there are no vesa driver on MIPS. > > Holger > > > > -- > Holger Wansing <hwans...@mailbox.org> > PGP-Fingerprint: 496A C6E8 1442 4B34 8508 3529 59F1 87CA 156E B076 > -- YunQiang Su
