I can never log into desktop. its always stuck at black screen, even in rc9I tried the rc9 and also got the black screen. I then remotely logged into the router IP I had set for the Rock64 (4G). I then used PUTTY and a SSH tunnel. The Rock64 had completed the boot and was running. I then used a VNC remote after installing tightvncserver, my favorite. The xstartup file under the .vnc folder has to be modified, but the Rock64 works well. The best I can tell is that the black screen is caused by the inability to frequency sync with the display. The programmers could fix this with a config.txt file where the monitor specs could be specified to sync. I have done this on the RPi SBCs with ubuntu MATE to fill out my screen. By all indications the Rock64 rc9 MATE version was trying to sync at 75 Hz and couldn't. This is probably true of all the release candidates (RCs) for ubuntu MATE.
For anyone wanting the xstartup edit, it is below:
#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#x-window-manager &
# Fix to make GNOME work
# export XKL_XMODMAP_DISABLE=1
# /etc/X11/Xsession
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
export XKL_XMODMAP_DISABLE=1
export XKB_DEFAULT_RULES=base
/usr/bin/mate-session
Your fix, can the ROCK64 then use 3D acc?
Sorry, this is not a fix, but a way to remotely have a desktop. I don't think 3D acceleration would work in this case. I just want people to have a way of seeing what is going on with the MATE desktop. This desktop is way beyond the LXDE. It is also beyond MATE on any RPi that I have. Just seeing it in action should give the people here hope that the ROCK64 is NOT a dead end product. You will have to wait until the GPU/monitor frequency sync problem is fixed before using the 3D acc. BTW, the RPi 2, 3B and 3B+ also have a somewhat similar problem, but have a table of monitor settings, pixel width, height and frequency in a (fat32 partition) config.txt file to force the GPU to sync and size. T'aint elegant, but it works really well if you pick the correct settings
Okay, it was just so i could understand. My self i thing ROCK64 is a nice product.
Have just, tried the new RC build it works very nice and the performance is great. It needs 3D acc but i wait, and i will be very happy for ayufan when he get it to work :-)
But still big thanks from here, for the great work ayufan!
