Internal/Primary screen stays black after standby
I´m fairly new to bazzite but i like it really much so far. Running on a Legion Slim 5 laptop with one external screen attached via HDMI. Everything is working fine, but one issue is driving me nuts: in energy options i set standby when closing the lid even when external screen is attached. So far so good. Closing the lid sets my laptop to standby. Opening the lid wakes my laptop, but i only get a signal to my external screen (attached via HDMI). The internal (primary) screen stays black. Tried to restart X, no success. Strange thing is: when i unplug the external screen then i get signal to my internal screen. Even more strange thing is: you might think reattaching the external screen then would solve the issue. But it isn´t. After reattaching the external screen the internal screen goes to black, and there is only signal to my external screen. Only thing that works for me is to reboot to make both screens work again.
Tried searching for my symptoms but all i found was black screen after boot, update or login.
What did i miss? What else can i check? Is this a bug or maybe a misconfiguration?
Any tips are highly appreciated. Thanks!

Latest insight: when standby mode is called from the startmenu then there is no screen issue after waking up. So my issue seems to only appear when standby mode is called by closing lid action. Any ideas on this?
