@herwich I am in the same situation as you, since I also need to be on 18.04 for now.
I am having trouble with the display driver as well. My model is equipped with an NVIDIA T500 (same as yours), but installing any NVIDIA display driver higher than version 390 fails and drops be in tty mode. Have you had success with using display drivers other than nomodeset? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-5.4 in Ubuntu. https://bugs.launchpad.net/bugs/1942759 Title: No touchpad detected on 'HP ZBook Firefly G8 (1G3U1AV)' after fresh install Status in linux-signed-hwe-5.4 package in Ubuntu: Confirmed Bug description: Ubuntu 18.04.5 LTS The touchpad is not detected with or without the Logitech M705 mouse plugged in. cat /proc/bus/input/devices Outputs: I: Bus=0019 Vendor=0000 Product=0003 Version=0000 N: Name="Sleep Button" P: Phys=PNP0C0E/button/input0 S: Sysfs=/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0E:00/input/input0 U: Uniq= H: Handlers=kbd event0 B: PROP=0 B: EV=3 B: KEY=4000 0 0 I: Bus=0019 Vendor=0000 Product=0005 Version=0000 N: Name="Lid Switch" P: Phys=PNP0C0D/button/input0 S: Sysfs=/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0D:00/input/input1 U: Uniq= H: Handlers=event1 B: PROP=0 B: EV=21 B: SW=1 I: Bus=0019 Vendor=0000 Product=0001 Version=0000 N: Name="Power Button" P: Phys=PNP0C0C/button/input0 S: Sysfs=/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0C:00/input/input2 U: Uniq= H: Handlers=kbd event2 B: PROP=0 B: EV=3 B: KEY=10000000000000 0 I: Bus=0019 Vendor=0000 Product=0001 Version=0000 N: Name="Power Button" P: Phys=LNXPWRBN/button/input0 S: Sysfs=/devices/LNXSYSTM:00/LNXPWRBN:00/input/input3 U: Uniq= H: Handlers=kbd event3 B: PROP=0 B: EV=3 B: KEY=10000000000000 0 I: Bus=0011 Vendor=0001 Product=0001 Version=ab41 N: Name="AT Translated Set 2 keyboard" P: Phys=isa0060/serio0/input0 S: Sysfs=/devices/platform/i8042/serio0/input/input4 U: Uniq= H: Handlers=sysrq kbd event4 leds B: PROP=0 B: EV=120013 B: KEY=20 0 0 1500f02100000 43803078f900d401 feffffdfffefffff fffffffffffffffe B: MSC=10 B: LED=7 I: Bus=0003 Vendor=046d Product=101b Version=0111 N: Name="Logitech M705" P: Phys=usb-0000:00:14.0-4/input2:1 S: Sysfs=/devices/pci0000:00/0000:00:14.0/usb3/3-4/3-4:1.2/0003:046D:C52B.0004/0003:046D:101B.0005/input/input14 U: Uniq=101b-fc-92-33-df H: Handlers=mouse0 event5 B: PROP=0 B: EV=17 B: KEY=ffff0000 0 0 0 0 B: REL=1943 B: MSC=10 I: Bus=0019 Vendor=0000 Product=0000 Version=0000 N: Name="HP Wireless hotkeys" P: Phys=hpq6001/input0 S: Sysfs=/devices/virtual/input/input15 U: Uniq= H: Handlers=rfkill kbd event6 B: PROP=0 B: EV=3 B: KEY=80000000000000 0 0 0 I: Bus=0019 Vendor=0000 Product=0000 Version=0000 N: Name="Intel HID events" P: Phys= S: Sysfs=/devices/platform/INT33D5:00/input/input16 U: Uniq= H: Handlers=rfkill kbd event7 B: PROP=0 B: EV=13 B: KEY=81000300000000 5000004000 1e294000000020 0 B: MSC=10 I: Bus=0019 Vendor=0000 Product=0000 Version=0000 N: Name="Intel HID 5 button array" P: Phys= S: Sysfs=/devices/platform/INT33D5:00/input/input17 U: Uniq= H: Handlers=kbd event8 B: PROP=0 B: EV=13 B: KEY=2000000000000 0 0 0 0 1000000000000 0 201c000000000000 0 B: MSC=10 I: Bus=0019 Vendor=0000 Product=0000 Version=0000 N: Name="HP WMI hotkeys" P: Phys=wmi/input0 S: Sysfs=/devices/virtual/input/input18 U: Uniq= H: Handlers=kbd event9 B: PROP=0 B: EV=33 B: KEY=4000000000 0 1000700000000 2102400 0 0 B: MSC=10 B: SW=0 I: Bus=0003 Vendor=04f2 Product=b6bf Version=0013 N: Name="HP HD Camera: HP HD Camera" P: Phys=usb-0000:00:14.0-2/button S: Sysfs=/devices/pci0000:00/0000:00:14.0/usb3/3-2/3-2:1.0/input/input19 U: Uniq= H: Handlers=kbd event10 B: PROP=0 B: EV=3 B: KEY=100000 0 0 0 I: Bus=0003 Vendor=04f2 Product=b6bf Version=0013 N: Name="HP HD Camera: HP IR Camera" P: Phys=usb-0000:00:14.0-2/button S: Sysfs=/devices/pci0000:00/0000:00:14.0/usb3/3-2/3-2:1.2/input/input20 U: Uniq= H: Handlers=kbd event11 B: PROP=0 B: EV=3 B: KEY=100000 0 0 0 ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-5.4.0-81-generic 5.4.0-81.91~18.04.1 ProcVersionSignature: Ubuntu 5.4.0-81.91~18.04.1-generic 5.4.128 Uname: Linux 5.4.0-81-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.24 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Mon Sep 6 11:37:52 2021 InstallationDate: Installed on 2021-09-06 (0 days ago) InstallationMedia: Ubuntu 18.04.5 LTS "Bionic Beaver" - Release amd64 (20200806.1) SourcePackage: linux-signed-hwe-5.4 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.4/+bug/1942759/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
