deepin Hello everyone
I recently tested Deepin 25 (Stable ISO from June 26, 2025) on real hardware. My system is an Intel Xeon E5 with integrated UHD Graphics. All hardware was detected correctly and worked out of the box. Graphics, networking, display – everything was recognized without any problems. That part is really impressive. Big thanks to the Deepin team for the solid device support.
However, I’d like to share some problems I ran into during real-world testing.
1. Keyboard layout issue with encryption (LUKS)
Before installation, I edited the GRUB boot entry (with the e key) and added de_DE.UTF-8 to the kernel line. I also selected a keyboard layout without accent keys because I really need the " character. The German layout was applied but the key for " still didn’t work. Even when switching to US layout, that key remained completely unresponsive. It looks like something is broken deep in the input system. My impression is that Deepin 25 was primarily optimized for Chinese or Asian keyboard layouts, which makes sense locally but causes trouble for international users.
2. Installation flow could be improved
The current order of steps in the installer can be confusing. I think it would help a lot if the keyboard layout selection came first in the graphical installer. That way users can enter their names and passwords correctly from the beginning. My suggested order:
- Keyboard layout
- Username
- Computer name
- Password
- Sudo password
- Disk partitioning and encryption options
This would prevent many common input issues and make the installation smoother overall.
3. No more global single-click setting
In Deepin 23, you could set single-click for the entire system. In Deepin 25, this is limited to the file manager only. Many users prefer single-click for faster workflow. Also, people with limited motor control rely on it. I hope this option can be brought back system-wide.
4. UI design feels less unique than before
The interface is modern and well designed, no doubt. But I feel Deepin 25 lost a bit of its unique identity. Some parts now look very close to Windows, which may confuse long-time Linux or Deepin users. I personally liked the more distinct look and feel of Deepin 23. It would be nice to bring back some of that original character.
Final thoughts
Deepin 25 has great potential. Hardware support is excellent, and the AI integration is promising. But the issues with keyboard input and system behavior during installation really need attention. I hope my feedback can help improve the system further.
Thank you to the entire Deepin team for your work, and I wish you continued success with the project
