Pause Unpause Linux Boot Screen 1

Pause

How many time you wanted to pause unpause linux boot screen to check out some errors? This screen goes away too fast and you’re then prompted with login screen. Once logged in, you’re too busy doing something else that you completely forgot that error that slided through boot screen too fast. This is a quick and easy solution to pause boot screen so that you can read it without crunching though logs later on.

Best solution:

Ctrl+S to Stop
Ctrl+Q to Resume

Works best in Laptop.

If you have a full fledged keyboard, try

Scroll Lock and Scroll Unlock buttons.

Other suggested solutions are

Pause/Break button combination

(p.s. never worked for me, you some people reckons it worked for them.

Once you’re logged in,open a terminal window and type in

dmesg | less

and you see something like this:

[   12.814960] RPC: Registered udp transport module.
[   12.814962] RPC: Registered tcp transport module.
[   12.814964] RPC: Registered tcp NFSv4.1 backchannel transport module.
[   12.856736] FS-Cache: Loaded
[   12.868714] Key type dns_resolver registered
[   12.912022] FS-Cache: Netfs 'nfs' registered for caching
[   12.952379] Installing knfsd (copyright (C) 1996 okir@monad.swb.de).

Now you can just use SPACE BAR to scroll through the logs to find what you’re after. Quite ugly, eh!

GUI alternate is to use System Log Viewer and look for dmesg/message logs by date/time. System Log Viewer is built into pretty much any modern Desktop Environments (i.e. Gnome, KDE, MATE. XFCE, LXDE etc.).

Mine gives some errors like below:

15/10/13 10:23:43 PM    testing    kernel    [    0.294180] ACPI Error: Invalid/unsupported resource descriptor: Type 0x00 (20120913/utresrc-650)

15/10/13 10:25:19 PM    testing    NetworkManager[4730]    <warn> bluez error getting default adapter: The name org.bluez was not provided by any .service files

I think I’ll just ignore those errors for now!

Hope that helps.
