first a little context. I updated from 18.04 and run Xubuntu specifically. i updated to 19.04 and my wifi works and everything but for some strange reason for a few weeks now, no matter what i do, i cant get rid of this error. It pops up in the quick black screen that appears before my login prompt shows up. no matter what i cannot find anything to fix it, my wifi still works but that error appearing drives me up the wall. iwlwifi 0000:00:0c.0: BIOS contains WGDS but no WRDS if you want specifics theres the whole thing from the logs.
