Can't Switch To Integrated by optimus-manager

Hello, I’m trying to switch my graphics to integrated by optimus-manager. When I switch to nVidia, It’s working perfectly. But when i try integrated, I’m getting sometimes a black screen, sometimes Dell logo. But It’s being impossible to access desktop without restart. Can some1 help me?

Here is my working nVidia switch log: nvidia switch htt37ps -
Here is bad integrated switch log: intel switch htt37ps -

-sorry for bad English, not a native speaker-

I have no expertise in these things
but what I see in the info you provided is
that it is very much truncated
by your choice to only provide “Info” level log entries

Hardware information would be conducive (inxi … )
as well as full logs of something not working.

People here cannot see what you can see - only what you give them - the more information the better …

Inxi output:

CPU: 6-core Intel Core i7-8750H (-MT MCP-) speed/min/max: 900/800/4100 MHz
Kernel: 5.15.85-1-MANJARO x86_64 Up: 5m Mem: 2156.2/15716.1 MiB (13.7%)
Storage: 1.14 TiB (1.6% used) Procs: 293 Shell: Zsh inxi: 3.3.24

inxi has got quite a few switches
Look for how to post, how to provide good information.
these are the literal search terms … that I’d have to use
to find the posts to then link them here to give that information to you
… while you can do that “work” just as well
