Welcome back to the Manjaro community
As a new or infrequent forum user, please take some time to familiarise yourself with forum requirements, and the many ways to use the forum to your benefit.
Note: By virtue of using the Manjaro forum you acknowledge and agree to follow Rules and Guidelines outlined; so, you really should read them:
Required Reading

Work with us, not against us
It is important to provide as much actionable information as possible in your first post, rather than simply indicating there is a problem. Please also be prepared to provide output from commands if/when asked.
Simply waiting for others to ask you questions is counter-productive – typically, nobody has a 
at their disposal – and your clear, concise and accurate input is often relied upon in order to help you.
Please help others to make informed suggestions based on information you provide.
System Information
While information from *-fetch type apps might be fine for someone wishing to buy your computer, for Support purposes it’s better to ask your system directly; 
Output of the inxi command (with appropriate parameters, and formatted according to forum guidelines) will generate information useful for those wishing to help:
Suggested inxi command (use either):
inxi -zv8 |
(short-form) |
inxi --filter --verbosity=8 |
(long-form) |
| inxi man pages | (manual) |
If running `inxi` within a `chroot` environment
- Add
--color=0to the long-form command, or… - Change the short-form command to
inxi -zv8c0
