What is the difference between:

Hello,

Quick info: I’m running openSuSE 11.1, with the GRUB Bootloader, and I’ve been trying to find out how exactly the bootloader options affect my visual startup. The reason I need to know this is because when I choose the normal Linux start-up I get no visual at all, but when I use the Failsafe mode I get graphics pretty much as good as I need them. Only problem is I need the rest of Linux to start up as it normally would.

Below is the information and options I have recorded out of YaST - Boot Options

openSUSE 11.1 - 2.6.27.21-0.1
resume=/dev/disk/by-id/ata-MAXTOR_STM3500630AS_6QG0KA1C-part1 splash=silent showopts

Failsafe – openSUSE 11.1 - 2.6.27.21-0.1
showopts ide=nodma apm=off noresume edd=off powersaved=off nohz=off highres=off processor.max_cstate=1 x11failsafe

Could anyone explain how these two lines are differently affecting boot options?

Well, they’re all kernel parameters I believe, and they’re probably
largely documented online. The resume=/dev… is telling your system, if
it resumes, where the RAM data are stored (in a swap partition most
likely). The other two options on the first I’m not sure about.

Failsafe basically disables everything that could really cause a failure
including resume, power-management stuff, high resolution stuff, and
advanced hard drive features. What those all do exactly will probably
take a little investigation but I’m sure the data are out there.

Good luck.
