I have this problem today the first time. It is an Samsung notebook with NVidia chip. I using a new Lucid i386 installation (no upgrade from older Ubuntu version) from a USB-Stick (with PAE-Kernel). The second boot works perfect. No Strg-Alt-Fx work but the Power Button. === Xorg.1.log === X.Org X Server 1.7.6 Release Date: 2010-03-17 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.24-27-server i686 Ubuntu Current Operating System: Linux michael-laptop 2.6.32-24-generic-pae #42-Ubuntu SMP Fri Aug 20 15:37:22 UTC 2010 i686 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-2.6.32-24-generic-pae root=UUID=b9a28d98-8a98-4df4-bc12-18af03ac4703 ro quiet splash Build Date: 21 July 2010 12:47:34PM xorg-server 2:1.7.6-2ubuntu7.3 (For technical support please see http://www.ubuntu.com/support) Current version of pixman: 0.16.4 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.
