Which version of system do you use? Khadas official images, self built images, or others?
Ubuntu 22.04 emmc
Please describe your issue below:
`I am using Khadas Vim4, ubuntu 22.04. I need to customize Ubuntu for myself. For example, I want to have my own logo on the splash screen, I want the screen to open as a mirror by default, I want the bottom bar to be eliminated. I need to do these in Ubuntu’s configuration files. That’s why I need to do these once and adapt the operating system to myself. I couldn’t find the source and some of the information in the Khadas documentation is outdated. How can I access the config files? How can I find the file related to the change I will make? If anyone has any advice…
I need to make changes to the config file. I can use the screen in mirror mode on my computer on Ubuntu22.04. However, when I press the mirror option in the settings window in Khadas VIM4, it does not take any action and closes the settings window. For this, when I use the
$ xrandr --output <projector> --same-as <desktop>
command, which has the same meaning as the settings I just mentioned, there is no change.
I managed to change the logo on the boot screen,
I replaced the logo.bmp and logo.png files in
with the logo images I wanted and rebooted. Now the image I choose appears on the boot screen.
Other than that, I don’t want to make the changes I want to present something visual on my personal computer. I want to turn off the bottom bar, Bluetooth, and the use of the ctrl+alt+T keys on the keyboard on my Khadas (I want to turn off the functions of some keys on the keyboard). For this, I need to make changes to the config files and save the image of the final version. For example, in which config file will I find the changes I will make for the mirror setting I want to make on the display? Or in which config file can I find the keyboard related settings? I can’t find any information about these on the internet or forum.
Thanks to your help, I solved most things.
I cannot set the screen to mirror. I installed gnome-randr as you said. However, as far as I see in the github repo, there has been no development regarding mirror. If you have different information, what command should I use to project the same image on both screens connected to Khadas VIM4?
In this link, there is a possibility of adding dual feature while there is no dual feature in Vim3. Can I add the mirror feature to the system by making any changes in the location(/usr/local/bin/hdmi.sh) you mentioned here ?
You have activated this feature in Vim4. Where do you activate the Join Display feature in Settings > Display > Display Mode? Can I add a mirror feature by making changes to this file?
Ok, but I’m interested in vim4. If you have an answer about that part, I would like to know. Where do you activate the Join Display feature in Settings > Display > Display Mode? Can I add a mirror feature by making changes to this file?
