Updating the Linux Kernel
 
I'm in the process of updating SuSe 9.2, but have omitted the kernel update for the time being, because twice in the past, this update apparently corrupted Grub to the point that it prevented either SuSe or Windows XP from booting and I lost a large amount of data. It would be nice to have the latest kernel, but I'm unwilling to do this again, unless I know how to do this safely. I would rather have the old kernel, than to continue making the same mistake. However, due to other problems, I currently only have SuSe installed and operative, and since this had something to do with Grub, I believe that I can only update now, or never. I vaguely recall past advice, something about copying the original Grub file(s) and kernel, but I'm far too unsure of exactly what to copy and how to use it, to consider proceeding without some detailed instructions. Can anyone help me with this?

Trying to play safe I would make a SBM (smart boot manager, use google) boot floppy and a grub boot floppy. Between those you should be able to run just about anything, and recover from not a few mistakes.

I Googled and found websites for both, but I shall have to wait until the current update finishes to proceed. Have you actually used these to be able to recover from a situation such as I described? How about the original kernel, should I copy it to a floppy also? If so, where do I find it?

As I mentioned in the other thread, the update fixed the sound problem. But one thing that it didn't fix, that I hoped that it would, is the video output to the TV. In Windows, there is specific Nvidia settings to obtain Dual View, so that you can have apps on different screens. But so far, I've not found anything like that. Also the video on the TV jitters up and down rapidly. I have a feeling that this has to do with the resolution setting, because in Windows it is only 60mhz instead of 76mhz in Linux, which is the only value available in Linux. I do not know what the resolution should be in Linux for the TV, but I do know that the maximum for the KDS monitor is supposed to only be 60mhz. Is there some place that would let me control this myself?

You will need to read the grub manual (eg on the web) to configure and use it because so much depends on individual circumstances. One thing you can do is boot the grub floppy and do something like
Code:

kernel (hd0,<some_number>)/boot/somekernel root=/dev/a<some_number+1>
boot

and see what happens. Grub has the cat command to read any text file on your harddisk too. And, tab completion is neat.

This is the part that I don't care for. If I were more competent with Linux, then I wouldn't mind, but I am far from competent and am not yet comfortable dealing with anything much more than the desktop environment. I believe that I will put off any updates to the kernel, until my understanding improves.

You should upgrade the whole system to 10.0 because there are less bugs and problems with the newer versions.

I've been upgrading since 9.0 (I started Linux with Linspire 4.5 --> Mandriva 9.2 --> SuSE 9.0)

*--> = then*

I have never experienced a GRUB error when upgrading JUST the kernel. Furthermore, the Linux kernel 2.6.13 is not broken as 2.6.8 was a bit.

I have SuSe 10.0, but have stayed away from it, because of some remarks that others have made about it. Plus, the one time that I did try to install it, the entire system was inoperative. This was probably due to something that I did wrong, but I tend to stay with whatever works. I'm am curious about your statement about the 2.6.8 kernel being broken though, what was wrong?

it was really bad with games, I don't know, but when I was running games on 2.6.8. Games like America's Army & Enemy Territory were performing worse than 2.6.13 kernel (SuSE 10.0). Anyother thing is that Cedega didn't work well with it with the locking up of system, etc.

Re: Updating the Linux Kernel
 
That may well be true. I have had problems with game performance, and with some games that don't initiate at all. However, the games that I actually care about do work okay, so I wouldn't update just for the others.
