I used the restricted module installer from the desktop. You have to wait for the driver to download and the installer my vanish or seem like it crapped out on the download, but it should still be going. Check in /var/cache/apt/archives/partial/ and there should be where the driver is downloading, once it moves up to /var/cache/apt/archives it will install (or maybe not, can't remember) or you just start up the driver manager again and activate it again and it will install. Works fine from fresh install of Ubuntu 8.10, but the restricted driver installer thing is flaky.
Edit: Making own thread for own problem instead of hijacking this one.
Well it seems i have to install U 8.10 then - I wanted to avoid that I guess there is still a tiny fault in the packageing. The problem is my test system has got only 1 GB ram and in live mode thats too few memory for running my script... My nvidia script definitely runs fine there. Will tell you when it is done.
Well now the script is fixed, the patch is much bigger than before, because it changes a few files more. Also it adds a divert for libglx.so, which is only in the xorg 7.4 dir. The default installer works, but it does not use dkms.
