Can you provide the output of lsmod and dmesg with the laptop attached to the dock and 1.173.3 installed? I still can't see how any of the updates between those versions are to files which would be used by your laptop.
For reference, here is is the list of files added or updated between 1.173.2 and 1.173.3. The amdgpu files won't be used at all by the bionic 4.15 kernel, but you have Intel graphics hardware anyway. You do have an Intel wireless card, but not one which uses the wireless firmware which was updated. The others are not for devices which would be found in a laptop. amdgpu/vegam_ce.bin amdgpu/vegam_me.bin amdgpu/vegam_mec.bin amdgpu/vegam_mec2.bin amdgpu/vegam_pfp.bin amdgpu/vegam_rlc.bin amdgpu/vegam_sdma.bin amdgpu/vegam_sdma1.bin amdgpu/vegam_smc.bin amdgpu/vegam_uvd.bin amdgpu/vegam_vce.bin iwlwifi-9000-pu-b0-jf-b0-34.ucode iwlwifi-9260-th-b0-jf-b0-34.ucode mellanox/mlxsw_spectrum-13.1620.192.mfa2 qed/qed_init_values_zipped-8.37.2.0.bin -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1811860 Title: Display ports on Lenovo docking station stopped working after upgrade of linux-firmware 1.173.2 -> 1.173.3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1811860/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
