I have a Toshiba laptop that I am using with an external monitor. After jumping through many hoops to get this to work in the first place, I have a problem. My previous configuration was as follows:

LVDS:

  • Disabled

VGA:

  • Enabled
  • Recommended Resolution (something like 1800/900)

Before I disconnected, I reconfigured it so that VGA was disabled and LVDS was running at the recommended resolution. It worked fine, and I shut the computer down. When I turned the computer on again, I got to the KDE login screen fine (I'm using KDM). But when I try to log into KDE, I get a black screen (though I hear the login sound). When I shutdown the computer and reboot, I can log into GNOME just fine. But when I try to log out of GNOME, everything hangs again.

Does anyone know what is going on? does anyone know of a solution to this problem?

NOTE: When I was using the external monitor, my resolution and monitor settings only took place after I logged in. Before then, it used the default settings of mirroring screens, which made the login screen bloated. This may have something to do with it.

    Did you save the new resolution settings as default (System Settings | Display and Monitor ...set as default)? Feb 14, 2012 at 13:25
  • No. What does that do?

  • @SlobodanKerda: If you put that in an answer, I'll accept it. It worked perfectly.

OP solved this by setting the display configuration as the default (System Settings | Display and Monitor ...set as default).

  • I know. I have done that, but I asked this before I was that comfortable with SE.
