"Maximum number of clients reachedCannot open display:" kubuntu 22.04.1 LTS

pl flag

Since today, after some time I can't open anything. If I reboot I can open everything as usual.

If i try to open in the terminal this is what I got:

"Maximum number of clients reachedThe futex facility returned an unexpected error code."

I did

sudo lsof | awk '/libX11.so/ {clients[$1]++;} END {for(c in clients){printf "%s\t%s\n", clients[c], c;}}'

and the result was

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.
