Change to Lower Resolution

[Cucuk Cabut]

Dear all,

 

I have been install the cubietruck using "Armbian_4.5_Cubietruck_Ubuntu_trusty_3.4.109_desktop" image.

It looks working, but i can't see desktop display.

 

Everytime the cubie boot, the monitor will showing "change resolution to 1440x900"

 

How to change the cubie resolution to the lower one?
or should i use monitor with higher resolution then i can change it?

 

please advise.

According to my notes I have done this some time ago:

nano /boot/boot.cmd

# example:
# change example from
# disp.screen0_output_mode=1920x1080p60
# to
# disp.screen0_output_mode=1024x768p60

mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr   

In my case it was also necessary to force VGA mode.

Hey EtlARM!

How did you force to VGA mode?

 

If I only change the line with the resolution it only changes to 720p -.-

 

Please help me:)

Hi Steevo!

 

According to my notes I have done this:

bin2fex /boot/script.bin /boot/script.fex
nano /boot/script.fex

#change these lines
screen0_output_type = 4
screen0_output_mode = 4
fb0_scaler_mode_enable = 1

fex2bin /boot/script.fex /boot/script.bin

I also wrote down these links, as they probably provided some information about the reason I did the changes above...
