The problem is, that they freeze as soon as the system tries to start the X system. It happens even before any log is written. This happens almost every time (for some reason it sometimes work, but 99% it fails). When i change the graphic driver in xorg.conf from intel to vesa it mostly works, but still i sometimes get a flickering screen, but this can mostly be resolved using ctrl+alt+backspace (sometimes you have to try this twice). We use the 1024x768 and 24 bit colors, so this shouldn't be the problem. Does anyone know a fix for this problem? ______________________________________________________ This is an issue with the graphics, it gets initialized in the wrong way ( driver ) The installer does not recognize the correct video chip during install. If you boot the system in runlevel 3 and then change the driver to i810 in the device section of /etc/X11/xorg.conf : Section "Device" Identifier "Videocard0" Driver "i810" EndSection Good luck, Edwin
