    Install older kernel?

    I using an Acer 751h netbook with the intel dma500 chipset. To get the corrent resolution for this machine I need to install poulsbo. This worked okay with karmic 9.10 and the .14 kernel. However newer kernels such as .20 or .21 don't seem to work. Can I install the .14 kernel into the Lucid and if so, how?
    Thanks for your time.

    Re: Install older kernel?

    The 'pat' answer would by 'yes, you can' but, I don't know if using a kernel built for Karmic is going to work in Lucid. Pulling the kernel via Synaptic, kpackagekit, or the CLI would require that you add the repository back for Karmic, update the package cache, and then pull/install the desired kernel.

    But again, I don't know what this would do.

      Thanks for your answer Snowhog. I am dual booting 9.10 with Lucid as an experiment for the time being. So I'm willing to try and see what happens. If it doesn't work out, I'll just re-install.
      But how do I 'pull' the .14 kernel from Synaptic? Do I have to use the search function in there? Is it a (fairly) simple process.

        You have to add the appropriate 'karmic' repository. Given that you are using Lucid now, your Ubuntu repositories will now reference Lucid, which is why you can't find the lower, Karmic kernels via a search.

          An example

          Making an additional sources list:
          Code:
          kdesudo kate /etc/apt/sources.list.d/karmic_sources.list
          Dropping there:
          Code:
          deb [url]http://archive.ubuntu.com/ubuntu/[/url] karmic main restricted
          
          deb [url]http://archive.ubuntu.com/ubuntu/[/url] karmic-updates main restricted
          Saving and exit.

          Updating package database
          Code:
          sudo apt-get update
          Now there are - among other things:
          Code:
          apt-cache search linux-image
          ...
          linux-image-2.6.31-21-generic - Linux kernel image for version 2.6.31 on x86/x86_64
          ...
          Installing:
          Code:
          sudo apt-get install linux-image-2.6.31-21-generic linux-headers-2.6.31-21-generic linux-backports-modules-2.6.31-21-generic

          Gain

          Lower CPU load. Here the average CPU load (idle) is lower 10-15 % with the older kernel.

          Loss

          KMS/DRI2 - is it loss ? Here the gain seems to be greater than the loss.
