Linux won't start after driver installation

Question

linux

I installed Lubuntu for myself, but the headphones did not work, I decided to install the driver, I found a topic on rutracker, with drivers from realtek, there were also drivers for linux, I downloaded it and installed it, after rebooting, where there should be a screen for entering passwords, a black screen appears with a bunch of errors, the keyboard and mouse do not work, what should I do?

Answer 1

Solutions:
1) Yubunta has a Recovery download, try it through it.
2) Press any key at boot to exit to the grub menu. Edit the boot line by adding init=/bin/bash . Next, after booting, remount the root with the command mount -o remount,rw /. After uninstall/fix the kernel.
3) boot from LiveCD or USB, mount HDD, restore kernel or kill driver. The kernel is in the /boot directory . Drivers in /lib/modules/ <kernel version>

Answer 2

No more downloading obscure drivers =)

Answer 3

How to start the system? Is there any way to revert the changes?

Answer 4

a black screen appears with a bunch of errors... what to do

Read and understand (using, for example, Google) what kind of errors.
The next time (apparently, after reinstallation), do not just mindlessly copy and execute commands, but try to understand what they do and what they can lead to.

Answer 5

Well, it's most likely that the hornbeam has flown, dig in the direction of restoring the hornbeam (GRUB) =)

Answer 6

You drop this thing. This is ubuntu. Everything is in standard turnips, and what is not there, there is a launchpad for that. Never put anything from the source, especially xs from where.
