ralf, if it is a simple procedure to enable the ATI graphics chip, i think that would be a helpful troubleshooting step... as far as i know, in this PPA <a href="https://launchpad.net/~falk-t-j/+archive/lucid">https://launchpad.net/~falk-t-j/+archive/lucid</a> , falktx has patched abogani's realtime kernel with the patches necessary to utilize the proprietary nvidia drivers... i use the PPA purge feature in ubuntutweak when testing a PPA with so many different packages in it... another easy trouble-shooting step would be to download KXstudio, run it live, and see if you can get to the desktop, and see if you can boot the -realtime kernel, see what graphics driver is being used, and what kernel version... <div class="gmail_quote">On Sun, Oct 3, 2010 at 1:41 AM, Ralf <<a href="mailto:ralf.mardorf@alice-dsl.net">ralf.mardorf@alice-dsl.net</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> <div> Hi all :) building a kernel-rt failed.
