Disable screen blanking on text console
To verify what timeout the kernel uses (in seconds) for virtual console blanking via
$ cat /sys/module/kernel/parameters/consoleblank
To change that timeout (in minutes, 0 means disable blanking)
$ setterm -blank VALUE
You can give more parameters to setterm
$ setterm -blank 0 -powersave off
To permanently/automatically disable virtual console blanking on startup you can either
- add the consoleblank=0 kernel parameter to the kernel command line
- add the setterm -blank 0 command to an rc-local or equivalent startup script
- add the setterm output to /etc/issue since /etc/issue is output on every virtual console
setterm -blank 0 » /etc/issue
