Do not see the options above


#1

My TV is 14 inches.
Ubuntu does not see integer.
I just see the folder.
If I put the course above you can see a few letters of the options above.
How can I see full ubuntu on TV so I can use it?
Thank you

You can follow below step to have a try.

HDMI Overscan

root@Khadas:~# echo 10 10 1909 1069 > /sys/class/graphics/fb0/window_axis
root@Khadas:~# echo 0x10001 > /sys/class/graphics/fb0/free_scale
Tips: window_axis parameter valued as: left + bottom + right + top

  • left + right = 1919
  • bottom + top = 1079

If you want this change as a permanent. You can modify the file /etc/initramfs-tools/scripts/local-top/khadas_init.sh

 echo 0 > /sys/class/graphics/fb0/free_scale
 echo 1 > /sys/class/graphics/fb0/freescale_mode
 echo 0 0 1919 1079 > /sys/class/graphics/fb0/free_scale_axis
-echo 0 0 1919 1079 > /sys/class/graphics/fb0/window_axis
+echo 10 10 1909 1069 > /sys/class/graphics/fb0/window_axis

Hi fym73,

You should execute echo 10 10 1909 1069> / sys / class / graphics / fb0 / window_axis NOT root @ Khadas:~#echo 10 10 1909 1069>/sys/class/graphics/fb0/window_axis.

Please try the following commands.

  • Change to root user:
khadas@Khadas:~$ sudo -i
[sudo] password for khadas: 
  • Then execute:
root@Khadas:~# echo 10 10 1909 1069 > /sys/class/graphics/fb0/window_axis
root@Khadas:~# echo 0x10001 > /sys/class/graphics/fb0/free_scale

Good Luck!

Thanks.

Casi se ve lo de arriba. Falta un poco más para verse todo.
Algún cambio?
Gracias


#6

root@Khadas:~# echo 10 10 1869 1049 > /sys/class/graphics/fb0/window_axis
root@Khadas:~# echo 0x10001 > /sys/class/graphics/fb0/free_scale

Así se ve bien de los lados y de abajo.
Pero falta que se vea completo de arriba.
Algún cambio?
Gracias

Hi fym73,

Sorry, I can not understand you well. I use Google translater, but still confused.:disappointed_relieved:
So could you please post it in English?

Thanks.

You do not see the entire screen of Ubuntu mate.
I put this:
root @ Khadas: ~ # echo 10 10 1869 1049> / sys / class / graphics / fb0 / window_axis
root @ Khadas: ~ # echo 0x10001> / sys / class / graphics / fb0 / free_scale
Now it looks good by the sides and the bottom.
It is missing all the way up.
What do I have to put in order to see the complete top?
Thanks

Hi fym73,

What’s the resolution of your TV?

Thanks.


#11

HD ready
I believe that
1366 x 768
Thanks


#12

Hi fym73,

I don’t have 1366x768 display screen now, but you can try the followd commands:

root@Khadas:~# echo 10 20 1909 1059 > /sys/class/graphics/fb0/window_axis
root@Khadas:~# echo 0x10001 > /sys/class/graphics/fb0/free_scale

#13

With your advice already looks good.
That looks good
root @ Khadas: ~ # echo 10 30 1869 1049> / sys / class / graphics / fb0 / window_axis
root @ Khadas: ~ # echo 0x10001> / sys / class / graphics / fb0 / free_scale

What do I do to keep it permanently?
I open the file khadas_init.sh
I give display.
Can not be modified.
It is read only.
How do I modify the file? Thanks


#14

Modify the khadas_init.sh file
Modify line 9
Remove echo 0 0 1909 1079> / sys / class / graphics / fb0 / window_axis
I put echo 10 30 1869 1049> / sys / class / graphics / fb0 / window_axis

The changes were saved.
I deleted Ubuntu.
I turn it on.
It looks bad.
It looks like before.
What do I have to put in the khadas_init.sh file?
Thanks


#15

Hi fym73,

After modify khadas_init.sh, you need to update the initrd, try the following commands.

# mkinitramfs -o /boot/initrd.img "4.9.40"
# mkimage -A arm64 -O linux -T ramdisk -a 0x0 -e 0x0 -n "initrd"  -d /boot/initrd.img  /boot/uInitrd
# reboot

#16

Where do I put that code?
In what file and on what site?
Sorry for the inconvenience.
Thanks


#17

I put it in the khadas_init.sh file.
Still the same.
Nothing changed.
What do I have to put in order for these changes to be permanent and where?
Thanks


#18

Hi fym73,

You can put them in /etc/rc.local too.

root@Khadas:~# vim /etc/rc.local

Add them here:

# Setup LED: breathing if bootup completed
echo breathe > /sys/class/leds/red/trigger

echo 10 20 1909 1059 > /sys/class/graphics/fb0/window_axis
echo 0x10001 > /sys/class/graphics/fb0/free_scale

exit 0


#19

Yes now.
Perfect.
Thank you very much.
Have a good day.
