    If you want scrollback in a framebuffer console, use tmux like a normal person, you probably want to anyway.

      "That code is now in Linux 5.9-rc6 and the performance is back on track with Linux 5.8 while I will have out more benchmark numbers soon on the revised Linux 5.8 vs. 5.9 performance state"

      There still may be regressions in 5.9 if its at 5.8 levels of performance, given that the FSGS patch was making things quite faster from what I remember... but let's wait for the benchmarks....

        Now Linux has matched MS-DOS levels of scroll back!

          Why the hell would I want to use something this overcomplicated if I could just press shift+Page Up/Down... I will rather use the good old GNU Screen.

            Scrolling on Linux console and many terminal emulators: Shift-PageUp/PageDown = 2 keystrokes:
            - hold Shift
            - press PageUp/PageDown

            Quit with any key.

            Scrolling on tmux: Ctrl-B, PageUp/PageDown = 3 keystrokes:
            - hold Ctrl
            - press B (and release Ctrl)
            - press PageUp/PageDown

            Quit with Ctrl-C.

            And what if I don't want the green bar at the bottom?

            Furthermore how can I tell the kernel to redirect all its output to tmux and launch tmux at boot?
            Otherwise how else am I supposed to scroll through kernel/systemd messages in case something goes wrong? .-.

              Yea, I never could get used to tmux either.

                I am on debian Sid/unstable. It seems debian removed soft scroll even from their 5.8.0.2 kernel (5.8.10). 5.8.0.1 works fine though.

                  Yeah, good luck scrolling the kernel output when your system cannot even reach the init.

                    You wouldn't have that problem if you ran Linux on a VM or via WSL like all the cool kids. Luckily Windows is rock solid so I can scroll my command prompt when the kernel crashes.

                    That's a joke.
