Disabling IPv6 leads to black screen on reboot

us flag

I tried disabling IPv6 using /etc/sysctl.conf and after a reboot I cannot get into any of the two DE that I have installed. Tried both GNOME and KDE Plasma. The SSDM login screen does show up but after successfully logging in I get a black screen.

Ctrl + ALt + F2 does work and if I remove the lines that are supposed to disable IPv6 using Vim and reboot, everything seems to work normally.

This is what I added at the end of the file:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

My question is, how can I even begin to troubleshoot this?

Does reverting the changes solve the problem?

Yes but there is no way to disable the IPv6 otherwise.

A search for "disable ipv6" here suggests that is not true. Also, the solution that you mentioned on this question is incomplete. Did you follow all of the steps for this particular solution?

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.
