Re: changing bootup parameters
Good time of the day, Jude. You worte: No point in doing that at all. If you want to see those messages after login as root or as sudo root do dmesg dmesg.log. Then less dmesg.log will let you view those messages one screen at a time. Also for a You can shorten that to dmesg |less - no need to file redirection (in some cases like no free space it even can be more useful, IMHO) :o) Sthu. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Thanks Sharon. Try editing grub at the boot screen and appending:- video=uvesafb:mode_option=1024x768-24 NOTE: modify the resolution and colour depth to suit. That works for me - I run Nvidia drivers so YMMV Also remove quiet if you want boot trivia If that solves your problem (the framebuffer making the boot messages too small to read) edit /etc/default/grub to make the changes. Don't forget to # update-grub afterwards.

Re: changing bootup parameters
Can you disrupt something if it is out of the ordinary while the system boots up? If not, you may as well wait until after login to find out what happened. The only possible case I can conceive of where what you want to do makes any sense is if a change was done to the system; the system is being rebooted, and there is a high probability you will never make it to login without disrupting the boot process to change something.

I suspect you speak for many users Jude, for which reason I put a boot splash up for them. Some of prefer to know what's happening as it happens though. That's why plymouth, and the quiet parameter are options. And that's the beauty of Debian. We have choices instead of having our options limited due to a narrow definitions of needs being foisted on us. Instead of having a choice between a blackbox recorder *or* a windscreen - we can have both. This allows people to know about minor problems or warnings before they become show stoppers, without having to parse dmesg (or /var/log/dmesg.0).
