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.
