Other behavior is that when it ends booting and before login into the system, if I change to a console (with Ctrl+Alt+F1 for example), the screen shows the console for less than a second and goes black again and if I go back to the GDM screen (with Ctrl+Alt+F7) it tries to show the GDM screen for less than a second before going black again. > It seems more likely that the first thing you see is the GDM login > screen.

Remember that when I turn on the computer after this happens I don't see even the Asus screen at the beginning. > Have you configured your system to use a graphical framebuffer > console?

So, it seems to be something related with the normal way to shutting down the computer from the Gnome desktop environment. > c) What happens if, after logging into gnome, you switch to a console > (i.e. ctrl+alt+f1), login and run "halt"? > Off course it works the same way as point (a) :-) > I wouldn't suggest you try installing KDE, but as a last resort you > might play with installing KDM.
