i just installed android x86 9.0c and i don't know why it doesn't boot on GUI mode and it boots only in commandline then after some seconds i can only see just a dash appearing and disappearing. I have tried to put my graphics settings to vboxvga and disabled 3D acceleration but it still doesn't work. What else i can do to fix this problem?
