Bug GUI Armbian on Pinebook


Recommended Posts

Want Armbian t-shirt or a cup?

Most likely because 3D acceleration needs to be disabled. Its not working very well on some versions.

 

Try this - run this as root and reboot:

echo 'Section "Device"
Identifier    "Default Device"
Option        "AccelMethod" "none"
EndSection' >> /etc/X11/xorg.conf.d/01-armbian-defaults.conf

Ok, this is my new file /etc/X11/xorg.conf.d/01-armbian-defaults.conf

 

Section "Monitor"
    Identifier        "Monitor0"
    Option            "DPMS" "false"
EndSection
Section "ServerFlags"
    Option            "BlankTime" "0"
    Option            "StandbyTime" "0"
    Option            "SuspendTime" "0"
    Option            "OffTime" "0"
EndSection
Section "Device"
    Identifier    "Default Device"
    Option        "AccelMethod" "none"
EndSection

But the problem persists :(

As a temporary workaround  and until further investigation you can use armbian-config to switch back to the sunxi64-legacy kernel which contains 5.4 branch.

 

I downloaded Armbian_20.08.1_Pinebook-a64_focal_current_5.8.5_desktop.img and booted it from an sdcard, and seem to have the same issue: the armbian login window just briefly shows up, before the screen seems to go off.

 

If you just blindly type into the black screen you can see in syslog via ssh that you still log on..

 

Indeed switching to 5.4.62 seems to be a temporary workaround; now the armbian login screen does not disappear, and things seems to work normally..

 

I have no clue what's going on here, indeed sth with the new kernel?-)

Yes, I reboot many times and the problem persist... The computer load XFCE4, this connect the Wifi and after 5 seconds the screen is black...

maybe you should - like on my Pinebook- set the display brightness via /etc/rc.local?

#set display brightness
pkexec /usr/sbin/xfpm-power-backlight-helper --set-brightness 8

I did read out the actual dim value as 2:

#read-out display brightness
pkexec /usr/sbin/xfpm-power-backlight-helper --get-brightness
2

and I did set (via /etc/rc.local) a for-me-default value of 8
A value of 10 (max.?)was to bright for me :)

Changed back to kernel 5.8.5, and changing the brightness like this just shows me a brighter black screen ;-) Issue remains the same, no output to the pinebook's screen,  can login by typing my password in the black screen, see the login happening via ssh..
