I installed Ubuntu 22.04 on my laptop Lenovo Legion s7 no dual boot only Linux. After installing the Nvidia drivers from Ubuntu Software & Update version NVIDIA driver metapackage from nvidia-driver-525 (proprietary)

After installing drivers and rebooting wifi adaptor and bluetooth not found, and touchpad is not working.

I tried to delete nvidia drivers, with sudo apt-get --purge remove "*nvidia*"

The biggest issue is that I can not update or upgrade anything because of lack of internet. I can not even use ethernet.

I can not even connect to internet sharing it via usb from phone. But the usb is working.

Troubleshooting:

ifconfig -a


Command 'ifconfig' not found, but can be installed with:

sudo apt install net-tools

sudo lshw -c network


[sudo] password for eadmin:

Please edit your question to show the result of the terminal commands: `sudo modprobe iwlwifi` and also: `sudo dpkg -s linux-modules-extra-$(uname -r) | grep Status` Can you select an earlier kernel version at the GRUB menu and boot into it? Does the wireless work in the earlier version?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
