    kernel upgrade?

    I use kubuntu 8.04 on my compaq evo n600c. Performance is good, but system crashes a lot.
    After a lot of searching i found a topic on the ubuntu forum with a lot of people having the same problems, the seem to be kernel related. My system has the 2.6.24-2 kernel. I try'd generic and real-time. So i was patiently waiting for a kernel upgrade, but i guess this won't be released for 8.04.
    I was pretty surprised to find out that 8.10 has a kernel that is much more recent.
    My problem is that kde 4 does not runs as smoothly as kde 3 on my laptop, so i want to stick to 3.

    Is there anyway to install the most recent kernel via package manager or should i compile this myself?

    Thanks for helping me.

    Yes, I think you are out of luck. You'll need to build it. The reason kernels are not backported is that you can introduce regressions in some platforrms/hardware, etc.

    Are you sure you'd rather not upgrade to Intrepid? In my oldish machine, KDE 41.latest with no desktop effects (Kompiz) is as fast as KDE 3, the only difference I notice is a slower logout. But bootup is a lot faster with Intrepid (I think, due to the new kernel 2.6.27 and xorg).

    In short, I think upgrading will be less pain, and compiling the kernel a nice geekish experience :-)

    Personally, I would try to avoid the vanilla kernel, and use the Ubuntu kernel from Intrepid (I am sure Ubuntu customizes things, adds unofficial modules, etc). If you really are going to take the plunge, these three articles show you how:

      You might also want to consider a kernel downgrade

      8.04 was shipped out with the 2.6.24-19 kernel, was it not? Or even the 17 version? Why don't you try those and see whether your laptop behaves. Still a damn sight easier than cooking your own kernel (but not half as much fun).

        Thanks for your answers! I was afraid that i would have to do it myself...

        There's an other thing that keeps me from upgrading and i wonder how you guys work around:

        In kde 3 i have a lot of options in the system settings menu. I can change my monitor settings and hardware settings, can change alsa / oss settings etc. In KDE 4 all these options are removed!
        How should i configure my system without these options? I know my way around in the terminal, but i don't want to use it for every simple change. I don't want to search for hours how to change my xorg settings using the terminal, and i dont want to search for hours to find out how to change a simple alsa setting using the terminal.

        How do you do these things?
        Thanks again!

          Well, the short answer (IMHO) is no: there is now way to make 8.10 as configurable as 8.04, and yes, I see your points. Also, you may have spent some effort getting sleep to work, etc., the usual laptop tweaks. I would probably wait for 2009.04 (which is exactly what I am doing on my eeepc).

          I think your best shots are Toad's excellent idea (try downgrading if possible, or just booting from older kernels if you see them in Grub), and upgrading just the kernel, in that order.

          Cheers!

            Alot by trial and error! Okay, not a very helpful answer, but an accurate one.

              To do a "downgrade" you could do a:

              Code:
              sudo dpkg -l|grep 2.6.24-21
              to see which bits and pieces you need and have installed for your machine. Here is my output although ymmv:
              ii linux-headers-2.6.24-21 2.6.24-21.43 Header files related to Linux kernel version
              ii linux-headers-2.6.24-21-generic 2.6.24-21.43 Linux kernel headers for version 2.6.24 on x
              ii linux-image-2.6.24-21-generic 2.6.24-21.43 Linux kernel image for version 2.6.24 on x86
              ii linux-libc-dev 2.6.24-21.43 Linux Kernel Headers for development
              ii linux-restricted-modules-2.6.24-21-generic 2.6.24.14-21.51 Non-free Linux 2.6.24 modules on x86/x86_64
              ii linux-ubuntu-modules-2.6.24-21-generic 2.6.24-21.33 Ubuntu supplied Linux modules for version 2.
              ii virtualbox-ose-guest-modules-2.6.24-21-generic 24.0.6 virtualbox-ose-guest module for linux-image-
              ii virtualbox-ose-modules-2.6.24-21-generic 24.0.6 virtualbox-ose module for linux-image-2.6.24
              Now you just install those bits for kernel 2.6.24-19. In my case that would mean

              sudo apt-get install linux-headers-2.6.24-19 linux-headers-2.6.24-19-generic linux-image-2.6.24-19-generic linux-restricted-modules-2.6.24-19-generic linux-ubuntu-modules-2.6.24-19-generic virtualbox-ose-guest-modules-2.6.24-19-generic virtualbox-ose-modules-2.6.24-19-generic
              It is not easy to read, granted. But then you just reboot and select the 19 kernel in grub (call up with ESC).

              After all, your notebook hasn't always misbehaved, or has it?

                Hmmm, i will see what works for me.
                I have a tiny spare disk, i can try to install 8.10 on that one and see if i can live with it.
                If not, a downgrade is a good option.

                Thanks for all help!
