There I change GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="i8042.nopnp=1 pci=nocrs" 3. sudo update-grub 4. restart Need to mention, until the above, the touchpad was not detected by the kernel(less /proc/bus/input/devices), and my system starts much longer after that. Sincerely think this operating system could be better. I'll delete this appeal if you won't admit it a bug --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.21 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: freesdx 1410 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2021-12-10 (2 days ago) InstallationMedia: Ubuntu 20.04.3 LTS "Focal Fossa" - Release amd64 (20210819) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 046d:c534 Logitech, Inc.
