Not sure this is related with the OP's problem, I have noticed that on my |
| 20 |
system I can scroll up in a console if it displays the output of a command, |
| 21 |
e.g. ls, but I cannot scroll up on the boot messages. Also, I cannot scroll |
| 22 |
up on the log messages on VT12. Is there something that I need to set up in |
| 23 |
the kernel? In the old days (perhaps different machine?) I used to be able to |
| 24 |
scroll up in both. |
| 25 |
|
| 26 |
$ cat /usr/src/linux/.config | grep SCROLLBACK |
| 27 |
CONFIG_VGACON_SOFT_SCROLLBACK=y |
| 28 |
CONFIG_VGACON_SOFT_SCROLLBACK_SIZE=128 |
