@Zaf9670 Please run "armbianmonitor -u" on the board and share the link

Sounds like an error with X. @ALL above: Did you recently update any packages? Please pastebin or attach the content of the ~/.xsession-errors file. Go and search for it if necessary "sudo find / -name .xsession-errors*"

With this, I will use the box to run a simple file synchronization service. I want to use the internal eMMc, what is the best way to use it?

updating so far, i installed arch linux on tv box @RaptorSDS I really want to learn how to do this, where are these pins? What adapter is this? Is this adapter the common one for reading electronic chips? I will love to help you with the information, in return I receive the knowledge Also, eMMC is unstable, I install and configure armbian normally, but when trying to update armbian, every now and then it freezes during the update and after restarting it no longer enters the system. After reporting the system crash here on the forum recently, I found myself on a mission to install a system that I feel comfortable with, Archlinux. With the idea of using the sdcard, with the command dd if=armbian-blabla.img of=device bs=1M oflag=direct status=progress I installed Armbian on the sdcard. With that, I already installed U-Boot and the Armbian boot, I just had to download the armv7 rootfs from archlinuxarm.org I had problems with the root password and file permissions. After copying the arch rootfs to the card, I discovered after trial and error that the files were corrupted. The solution was to redo the entire process. Now the system starts correctly, however, ssh would not start with the boot, and my board is an R29, I do not have HDMI access (and I suspect that not even the USB gadgets work, but I have not tested it yet). The solution was simple. With Armbian on the internal eMMC, I mounted the sdcard along with the dev, proc, sys and run partitions, and in chroot with the sdcard I configured ssh, pacman with pacman-key --init and pacman-key --populate archlinuxarm, and installed sudo to be able to do the basics. In addition, it was necessary to manually configure fstab and copy network settings (to make things easier) from armbian to arch.

A quick google search seems to suggest that the Orange Pi Lite is prone to overheat. Obvious question that you did not mention in your original question: Do you have a heatsink installed? Is there sufficient airflow? In general, are you sure you want to use this board with a mate environment? Even if you get to work around the heat issues. RAM and CPU are likely to cause this to be a bit of an underwhelming experience.
