How to locate the problem of being unable to enter the Deepin desktop environment?

I need some helps here.

You should try to describe the exact problem that you currently have and try to provide detailed information so other people can guess what's going on.

e.g.

• The exact issue you had
• Reproduce steps
• Error message that you've seen (if any)
• Software or system version
• Hardware spec (if you think it might relate to hardware)
• Any other info that you might think it can be helpful

So it happens when you attempt to login to DDE from a display manager? If so:

• Which distro are you using? If it's not a rolling release version, which version of that distro you're using?
• Which display manager are you using?

[topazus]

Thanks for your reponse. Yes, it appeared when I login to DDE from gdm display manager on Fedora 42.
