Hi Aaron~ I downloaded the mainline kernel 5.3.0 from the ppa you provided and installed as follows:
wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3-rc2/linux- headers-5.3.0-050300rc2-generic_5.3.0-050300rc2.201907281631_amd64.deb wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3-rc2/linux- image- unsigned-5.3.0-050300rc2-generic_5.3.0-050300rc2.201907281631_amd64.deb wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3-rc2/linux- modules-5.3.0-050300rc2-generic_5.3.0-050300rc2.201907281631_amd64.deb sudo dpkg -i *.deb I left my blacklist.conf unchanged (r8822be blacklisted, rtwpci not blacklisted). I rebooted and selected the mainline kernel from GRUB and added the rtw88.debug_mask=0x3ff linux cmdline option. But with r8822be blacklisted, wifi does not work even on mainline 5.3.0. I have attached the output from journalctl -b0. Here are the realtek kernel modules that are loaded: junbuntu@pj:~$ lsmod | grep rtw rtwpci 24576 0 rtw88 442368 1 rtwpci mac80211 847872 2 rtwpci,rtw88 cfg80211 708608 2 mac80211,rtw88 Should I try again but this time remove r8822be from blacklist.conf (and also do not blacklist rtwpci)?
