Hi! I'm a Brazilian deepin user and I like testing deepin on different computers, including low-end hardware.

Recently I had a problem with ZRAM on deepin 25. My previous systemd configuration was creating dependency problems with swap.target, and /dev/zram0 was not always being created correctly.

I fixed it by creating ZRAM only after the device is available, using the kernel ZRAM interface when necessary, and then activating the swap with a higher priority than the disk swap.

My final configuration uses:

• /dev/zram0
• ZRAM compression
• swap priority 100
• a persistent systemd service
• disk swap kept as fallback

After fixing it, ZRAM starts correctly at boot and the system remains stable.

I tested this especially because I like running deepin on older and low-memory computers.

I'm still learning Linux and my English is not perfect, but I wanted to share this because maybe it can help another deepin user. :)
