[opensuse] How do I manage kernels in opensuse
I would like to try out the realtime kernel but I have problems getting my Nvidia drivers working. I have the kernel-source installed. I wonder: -How do I manage kernel symlinks in openSUSE? -How do I get the Nvidia driver working? In Gentoo I would switch the kernel symlink to the rt kernel and reinstall the Nvidia driver then reboot in the new kernel. What is the openSUSE way? -- Regards, Aniruddha Please adhere to the OpenSUSE_mailing_list_netiquette http://en.opensuse.org/OpenSUSE_mailing_list_netiquette -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

While running the new kernel, invoke the nvidia installer? Joe -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I tried that by removing and reinstalling the nvidia driver with zypper. unfortunately this didn't work. What else can I try? It should also be possible to do this before rebooting if you change the symlink to the kernel source.

AFAIK the suse tools will manage the suse nvidia packages, which are built for the suse kernels - but if you're using the -rt kernel, you're going to be downloading the driver from nvidia.com and doing a manual install. Also, IIRC there are ways to build for a kernel you're not running, you'd have to run the nvidia installer with the help option to get the exact syntax needed, as I've never done that, but only remember seeing something about it in the nvidia installer options.

Thank you for answer. By looking around in yast2 package manager I determined that kernel-rt is at version 2.6.22.5-31. My current kernel is version 2.6.22.9-0.4. The current symlink points to 2.6.22.9-0.4. Changing this to linux-2.6.22.5-31-obj (with ln -sfn linux-2.6.22.5-31-obj) should solve the Nvidia driver issue.

The drivers built for the suse kernel won't work with the -rt kernel. I'd expect at the very least, no hardware-accelerated 3D, and perhaps a crash upon attempting to load the drivers.
Is there an easy way to manage kernel symlinks in openSUSE?
The ln command seems easy to me - but then again, I guess I'm not familiar with whatever "symlink management" software you've used before. In any case, I've not had to do any sort of manual kernel symlink management on suse. The kernel versions I've built all coexist happily in /usr/src/ along with the suse supplied kernels and the init scripts are smart enough to load the correct modules on boot.

There's no reason to switch the kernel symlink. You should be able to just add the new kernal to the grub files in the /boot directory (this allows you to boot to either the regular kernel or the realtime kernel by just selecting a menu item at boot time. read up grub... unfortunate the complete documentation in one of those dispicable Texinfo files rather than a man file. Unless you use emacs regularly, pinfo is easier to use than info, so pinfo grub. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Ok I can do that :). I also discovered that there is a kernel source available kernel-rt. You only see it when you search for it in zypper (in yast2 it's invisible).

Whatever method you use check symlinks /boot/vmlinuz for kernel, /boot/initrd for initrd. and /usr/src/linux and /usr/src/linux-obj for sources. I installed it recently, but I can't recall did installation changed symlinks. I can't recall why I didn't used it. Did nvidia compilation failed, or server didn't started. -- Regards, Rajko. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The last two links should not be required. In fact, these links should not be used at all. Use /lib/modules/`uname -r`/{build,source}. Th. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Aniruddha, That will be no problem. The kernel will install in /boot and the source will go in its own directory in /usr/src. I have 11 different kernels and kernel sources available for booting on a openSuSE 10 server. Like Rajko says, what determines which kernel is "active" is the sym links in boot that point to vmlinuz and the /usr/src/linux symlink that points to the "active" kernel source tree.

I don't know how to do it in Yast anymore. Yast changed between opensuse 10.0 and 10.3. The good responses I have obtained from the list suggest a manual download of the kernels and patches and then installing from the command line with "rpm -ivh" Evidently, as you have found, you can do it with smart. However, I have never used smart, so I can't speak to it. See my earlier post of "HowTo Install New 2.6.23.1-900.ccj58-default kernel and SAVE my present one too" Good luck. -- David C.
