Re: [Dorset] Editing grub menu config
This is what we said a month or so ago. On Sunday 01 Nov 2009, Andrew Morgan wrote: Hi Terry, I have just had to do the same thing on my work laptop which is now running Ubuntu 9.10. I'm not sure if this is the same in Kubuntu but here's the way I did it: Install StartUp-Manager. This can be found in Ubuntu Software Centre, or by running 'apt-get install startupmanager' if you prefer. This creates a launcher in System/Administration called StartUp-Manager. I think once you run this you'll work out how to change the default operating system, its the big obvious drop-down list box marked 'Default operating system'. :) I did change the Bootloader menu resolution (Advanced tab) which worked fine, but this simply ended up with the text becoming smaller. Would be useful if you have a lot in the list though. The other thing I did was edit /etc/default/grub and un-comment the last line: GRUB_DISABLE_LINUX_RECOVERY=true This gets rid of the (recovery) menu options. The difference between these and the normal ones is that the options 'quiet splash' are removed and 'single' is added. I have never used a recovery option and I'm sure I can edit the grub entry if I need to do this, also it looks slightly neater. This method didn't require any coffee products or logos, and you may have noticed that I have not quoted any text so I can't be accused of top- or bottom- posting. Aren't I good? :) ps. My work laptop shuts down/reboots in about 3-4 seconds! I was amased. But then it isn't much more than a default install + mpd. -- Terry Coles 64 bit computing with Kubuntu Linux -- Next meeting: Dorchester, Tuesday 2010-01-05 20:00 Dorset LUG: http://dorset.lug.org.uk/ Chat: http://www.mibbit.com/?server=irc.blitzed.orgchannel=%23dorset List info: https://mailman.lug.org.uk/mailman/listinfo/dorset
