[opensuse] OpenSuse 13.2 and grub2
I performed a new installation of OSS 13.2 on a laptop. As per default, it uses grub2. When the machine boots, I see a menu with options "Opensuse", and "Advanced". If I choose (or let the system choose by default) OpenSuse, then the machine proceeds to boot, comes to the GUI login screen, and at that point my keyboard and mouse do not work at all. If I choose "Advanced" from the grub menu, and then choose the latest kernel that is displayed, everything works fine. My question is whether there is away to see what options are being used by the various grub menu entries once the machine is up and running (as it is now and I'd rather not reboot it if I do not have to)? The old GRUB used a text based configuration file, which was fine but limited. The new one is much more dynamic in that most of the configuration is done via scripts, but it would be nice if it writes the "final results" and menu options etc somewhere for debugging purposes. If not, then is my only option to trace through the code of all the scripts to see what those options are presenting or reboot the machine and then examine the menu options?

cat /proc/cmdline I think that is what your asking. Greg -- Sent from my Android phone with K-9 Mail. Please excuse my brevity. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Greg Many thanks Greg. That does indeed show me that options used to boot

Press 'e' on the line in the grub2 menu when you have highlighted which "version" you want to boot into- Opensuse or Advanced. Hit "F10" to boot.

Thanks BC. Yep, I was afraid that was the only way and I would have to wait for the next reboot of the machine to find out. -- --Moby They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety. -- Benjamin Franklin -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Not quite. I thought that you wanted a quick view but now that you REALLY want to look then look inside /boot/grub2/grub.cfg (and read the beginning of this file as well) :-) .

The final result of running all those scripts , and yes they get arcane!, is written to /boot/grub2/grub.cfg. As BC says, you can see the single item you've chosen at run time, but if you want to see the whole of the menu and all the other settings & options and compare the the various menu entries side by side, you need to look there. -- /"\ \ / ASCII Ribbon Campaign X Against HTML Mail / \ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Thanks Anton - yep, I see it. I should now be able to compare the different boot option parameters after chasing down where and what some of the variables in the kernel line in grub.cfg are. -- --Moby They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety. -- Benjamin Franklin -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yep and it's so clear and transparent, the configuration just jumps out at you! /<sarcasm> -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
