I wonder if anyone has anyidea about this, I posted previously and got no reply. May laptop is 1.8 celeron + ati, I upgraded system > no X, tried reconfiguring X to no avail (X wouldn't boot at all, just seemed to lock up). I downgraded back to kernel26-2.6.23.8-1-i686.pkg.tar.gz, and kde loaded fine, but virtualbox wouldn't load (no front-end gui), no error logs generated, the command just hangs in the terminal. looked everywhere for the /usr/bin/vbox_build_module to rebuild the kernel module but dosn't seem to exist on the computer. Did an updatedb etc first to try and find it. Checked out the forum and of course all the posts mention to use that file. doing a pacman -Ql <package name> also it seems the file needed to rebuild the kernel module is not in any of them. Any Idea's appreciated. Richard
