xloem Posted June 20, 2020 Share Posted June 20, 2020 Armbianmonitor: https://siasky.net/vABcWfjCPFO6ggdrJIjhrwKshybBrbSSA_9MFXcr3FKPDA/armbianmonitor-2020-06-20T08:51-04:00.log I'm not familiar with the a64 graphics driver and some tty graphics software of mine is failing on Armbian Ubuntu Focal after working fine on the Bionic image. Earlier I was able to mmap() /dev/fb0 to display graphics in a tty. On Focal 20.04, running linux 5.4.43-sunxi64 , mmap() on /dev/fb0 is failing with EPERM (operation not permitted). Is this new error something anybody knows about or could give a link to find a possible driver change that's responsible? It seems there might be a few different video drivers on this system and I haven't looked at them before. /sys/class/graphics/fb0/name contains sun4i-drmdrmfb /sys/class/graphics/fb0/device/modalias contains of:Ndisplay-engineT(null)Callwinner,sun50i-a64-display-engine Thank you.
