Each time I boot into Fedora, I normally have a gnome-terminal open automatically with a screen session, but lately, that's not happening anymore. So I am opening a terminal manually to run screen, and I get
bull•~» screen -S xyz [21:40:44]
Directory '/var/run/screen' must have mode 755.
So each time, I chmod it accordingly, yet it continues the issue continues to happen after a reboot. All I did was give the screen executable the suid bit
bull•~» ls -l $(which screen) [21:41:10]
-rwsr-sr-x. 1 root screen 438840 Dec 20 07:03 /usr/bin/screen
so that I could share screen sessions with multiuser enabled. I've always done this, and it's never been an issue before.
