As the title states, how do I find, set, and maintain the screen's supported resolutions after rebooting via the CLI?
My Setup:
-----------------------
Raspberry Pi 5
- Raspberry OS Lite - Bookworm (I prefer to have as light weight OS as possibly, within reason)
Display - 43" TV
No keyboard/mouse
GUI setup - Openbox-----------------------
When I check "xrandr" with:I only get one resolution outputI have tired to set the mode with I then tried the gui version of "xrandr" and installed the "arandr" and connected up a keyboard and mouse to it..
I open up "arandr" and find these resolutions but...
----------------------
3840x2100
4096x2160
2560x1440
1920x1080
1920x1080i
1280x720
1024x768
800x600
720x480
720x480i
640x480
-------------------
But, "arand" doesn't give me a save option to maintain what I set it too.
If there is additional information can provide to help please let me know while I continue to look for a solution.

My bad, I didn't realize i was in this forum. I thought i was under the "troubleshooting" section
