Well, i just read on the Tech News board a new Kernel, 2.6.29 which has many improvements over the 2.6.25 version im using.
Im wondering, why doesent the kernel updates through regular Yast update function?
Is there another way of updating the kernel manually?
Thanks
What ver. of openSUSE?
Currently 11.1 is:
2.6.27.19-3.2
Give us a terminal output of:
zypper lr
and
:
uname -a

For any openSUSE release, the kernel will not be upgraded in such a way.
Only bugfixes will be integrated and released as updates. There are
kernel packages in the build service, though, including 2.6.29.
The latest kernels from the build service (release branches, vanilla
(unmodified), Factory HEAD) can be found here:
http://download.opensuse.org/repositories/Kernel:/
Use with caution, for experienced users. Kernel packages can be installed
in parallel.
Kind regards,
Andreas Stieger
im currently using 11.0
Could you guys give a little tutorial about how to install this new kernel ?
thanks

I think you should ask what kind of issues you could experience and what
is the “vanilla” kernel vrs the std one -ie is there things missing that
are normally compiled into the std kernels - before you do this.

sorry but i didnt understand a thing there, i mean, ive read that newer kernels are much better, 50% faster boot, etc
Um… I wouldn’t believe such rumors. Every new Kernel will provide new functions, bugfixes, modules etc., but still one should only upgrade a Kernel when needed. 50% less boottime? I don’t think so…
A Kernel can be upgraded just as any other package: activate the respective repository and install it via YaST or zypper.
Note that several kernels can be installed at the same time when they have different names, for example:
kalle@hoppers:~> rpm -qa | grep kernel
kernel-rtpae-2.6.25.20-jen70
kernel-pae-2.6.25.20-0.1
...]
…so you have to choose which one to boot in GRUB.
50% less boottime? That’s nonsense. 5 seconds, maybe 10.
It can be done, but as already said, this is for experienced users. You should know, that a distro is built as a whole, around a kernel. That’s what you’re breaking if you opt for a newer kernel.
Suppose it does bring you a 50% reduction on boottime…First, this is measured from GRUB till login screen, it would give me about 25 secs. But after that, the changes require that a apply a patch to and rebuild Vmware’s kernelmodules, that the NVidia driver is reinstalled etc.
BUT then again: i replaced the HDD in my laptop by an SSD, standard kernel speeded things up already, but the 2.6.29 kernel realy does make a difference.
So if it’s speed that you want, boot and run from SSD. My laptop “beats” it’s recent equivalents with HDD and a double amount of RAM. Not only in booting (full KDE4 desktop in 40 secs.) but also in starting apps. A slight delay exists when installing hundreds of small packages.
The kernel initialisation during boot time is the first part of the bootprocess which only takes 5 to 10 seconds at the most. The rest is loading services and modules.
The more services and modules you need the longer the bootprocess will take.
So it’s you that decides how long the bootprocess will take from grub to login screen, not the kernel.
So upgrading the kernel to that latest version will not improve the bootspeed. And another thing, suse build some suse specific features in the current kernel such as the bootsplash and support for hardware devices that might not be available in the kernel in other distributions etc…
You will loose all these thing, keep that in mind.
oh, seems ill be sticking with my current kernel then, too much issues for so small advantage
thanks everybody for the help and info
