Hi Aaron, I appended r8822be driver to blacklist.conf and then manually ran "sudo update-initramfs -u -k 5.0.0-21-generic" and rebooted. Still no wifi, however.
I have attached the output of dmesg. BTW this notebook has Realtek ethernet hardware, which is why kernel driver r8169 is loaded. Also, I don't know if this is relevant, but I have disabled all linux power management on this AMD Ryzen 7 gaming notebook b/c of issues when this computer enters power-saving mode. In "/etc/default/tlp" I set "TLP_ENABLE=0" and also appended the following parameter to my GRUB commandline: ahci.mobile_lpm_policy=0 Best, Jun ** Attachment added: "dmesg_linux-5.0.0-21.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1838133/+attachment/5279800/+files/dmesg_linux-5.0.0-21.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838133 Title: realtek r8822be kernel module fails after update to linux kernel- headers 5.0.0-21 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1838133/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
