Question how do I pausing boot messages?


On fedora 11 I get a kernel panic type message almost immediately after the grub. I'm sure the error is telling me what is wrong but it scrolls too fast and the message is buried.

Is there any way to slow down the boot messages, log them to a file, or page pause them?


It's a weird problem as it only happens when I put in a new graphics card. DSL linux boots fine. It's only Fedora.

Have a look at your /var/log/boot.log file or /var/log/messages file or try typing dmesg.

The pause/break key should work.

Is it really during boot or when the GUI is starting? If it is the GUI, check /var/log/Xorg.0.log.

Alternatively if you have a frame buffer enabled and the machine crashes on that, it is more complicated as I understand this cannot be disabled in Grub. (Or can it??)

It's not getting far enough to check any logs. The boot file is blank, nothing written in the /var/log/messages file and dmesg is no good as to check I need to access the HD from another computer.

You need to activate boot.log
I believe in fedora it is in
/etc/syslog.conf

So it should. In case it doesn't or is difficult to time, you can put a symbolic link to /sbin/sulogin in the boot scripts at the point where you want booting to stop so you can see what's happening -- especially useful if it's immediately before graphical mode starts.

You can use the 'linux rescue' option from the install DVD to set the 'initdefault' line (/etc/inittab) to 3 instead of 5 for bootup. This gives you a basic cli console.
You can then try


system-config-display --noui --reconfig

X -probeonly

startx

in that order
