Is there any way to tell if the USB-C port on my laptop will support DP Alt Mode? I've contacted the supplier but not had any reply.

I am running Ubuntu 21.04 with kernel 5.11.0-25

CONFIG_TYPEC_DP_ALTMODE=m

Laptop Acer Aspire A715-42G-R7NL

Wait till the supplier tells you. Or maybe the supplier has a support forum.

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.
