guidol Posted December 22, 2023 Share Posted December 22, 2023 Normally when you have installed a XFCE-Desktop image for the Pinebook A64 you could set the display brigthness with the following pkexec command to a readable higher level - like I did in the past (possible brightness values are 1-10 - on startup this is only set to 2): pkexec /usr/sbin/xfpm-power-backlight-helper --set-brightness 8 read-out command for the current value: pkexec /usr/sbin/xfpm-power-backlight-helper --get-brightness but on standard CLI-install pkexec and xfpm-power-backlight-helper are missing, so to use this command-line (in /etc/rc.local) you have to install these 2 packages: sudo apt install xfce4-power-manager pkexec 0 Quote Link to comment Share on other sites More sharing options...
Gunjan Gupta Posted December 22, 2023 Share Posted December 22, 2023 quick look into xfpm-backlight-helper shows it is manipulating files in /sys/class/backlight. If the goal is to do it from /etc/rc.local, probably you can do the same as well. 0 Quote Link to comment Share on other sites More sharing options...
guidol Posted July 1 Author Share Posted July 1 (edited) @Gunjan Gupta Today I did try the following images Armbian_community_24.8.0-trunk.205_Pinebook-a64_noble_current_6.6.31_gnome_desktop.img and Armbian_community_24.8.0-trunk.205_Pinebook-a64_bookworm_current_6.6.31_minimal.img on my 14" (1080p?) Pinebook non-Pro A64, but I do get only a black screen It didnt help to use echo 8 > /sys/devices/platform/backlight/backlight/backlight/actual_brightness or the pkexec-command The screen lights up, but to information on the screen. I had only (sometimes) access via a USB-Ethernet-Adapter. But at some boots the ethernet wasnt recognized and the onboard-Wifi doesnt sho up The last version I could get my screen to work - with a CLI-version of bookworm - is 24.2.0 of armbian (after update?) I dont know how to switch via 720p/1080p for the different screensizes of the Pinebook A64 non-Pro (I have 14" and not 11.6") BTW: after updateing the 24.2.0 of armbian via apt update/upgrade the system is also non-working (Black screen and no ethernet and no Wifi) Its has updated to kernel 6.6.31 and this was also the "death" to some of my OrangePi installations The "Community Editions" are at this time unuseable (because non-tested) - this could end in a bad reputation also for the supported devices - as I think. For me its software-obsoleszenz - rendering working hardware into a paperweight Edited July 1 by guidol 0 Quote Link to comment Share on other sites More sharing options...
guidol Posted July 2 Author Share Posted July 2 Like on the OrangePi's which have problems with the latest Community Edition (kernel 6.6.x and their armbian-firmware) I went back to the most actual stable image before kernel 6.6.x (non-Community Edition?) for the Pinebook A64 which can be found at https://armbian.hosthatch.com/archive/pinebook-a64/archive/Armbian_23.11.1_Pinebook-a64_bookworm_current_6.1.63.img.xz You do get a non-Desktop system with Armbian 23.11.1 Pinebook-a64 bookworm current kernel 6.1.63 then do a Kernel-Freeze in armbian-config -> system apt update/upgrade and you will end with a stable Armbian 24.5.1 Bookworm with Linux 6.1.63-current-sunxi64 This will recognize my 14" Screen, WiFi and Ethernet (USB) 0 Quote Link to comment Share on other sites More sharing options...
