PC freezes in GDM after 4.13 kernel update

Hi, I just installed the 4.13 kernel update and rebooted the computer. However, after GDM showing up my mouse and keyboard don't work, I don't know if it freezes or if it is a problem with my Microsoft wireless keyboard and mouse driver. The mouse and keyboard work for like 2 seconds then I can't use them anymore. Is there a way to use a fallback kernel without chrooting the system like I could with Ubuntu/Fedora?

Also, if you haven't cleared your cache, you can downgrade the kernel.

Is there a way to downgrade the kernel without chrooting it? I can't find my backup DVD because I just moved in and it's the only computer in the house right now

You can downgrade if you have Not cleared Pacman cache, If you have it's not possible.

Do you use grub? If so, Press E in grub to edit boot parameters, you want to add single as a kernel paramater, and then you can press ctrl+x to boot into a shell.

The line should look something like this: '''linux /boot/vmlinuz-3.2.0-24-generic root=UUID=bc6f8146-1523-46a6-8b\
6a-64b819ccf2b7 rw quiet' You want to add single to the end, --> linux /boot/vmlinuz-3.2.0-24-generic root=UUID=bc6f8146-1523-46a6-8b\
6a-64b819ccf2b7 rw quiet single

The wiki covers downgrading packages --> https://wiki.archlinux.org/index.php/Do … g_packages

If you cd to /var/cache/pacman/pkg you can benefit from alt-tab completion, see all cached packages, since Linux and Linux headers contain a bunch of numbers, might be hard to type it correct. If u ls you can use shift + pageup/dwn to scroll in cli and then downgrade to you're cached kernel of choice.

If you have cd to /pkg folder it's as simple as executing pacman -U 'package you want to downgrade' and hit enter.

I still advice you to read the wiki before downgrading, Pacman handles dependencies when downgrading, but not version conflicts.

Re: PC freezes in GDM after 4.13 kernel update

Thanks a lot for the detailed explanation, I forgot about the "single" command, I have systemd-boot but it worked! I had to downgrade VirtualBox and a module too. Do I have to make a bug report? When I know it will be safe to update my kernel?

Re: PC freezes in GDM after 4.13 kernel update

I would recommend you install linux-lts so you have a fallback kernel for when issues like this occur.
Unless someone reports the bug upstream it is unlikely to be fixed.  Without knowing the cause of the bug and tracking its progress in being fixed
it is impossible to know when the issue will be fixed and you could upgrade to a kernel not affected by the issue.
