Bug Description
Ubuntu 7.04 Feisty, laptop HP Compaq nx9105
External monitor only starts in the case it is already plugged in during startup. It runs then in "both" mode. However, when login screen is displayed, display is switched to external-only mode. There's no way out of this, known for me.
If external monitor is NOT plugged in during startup, and only plugged in after login, it is ignored. It only activates on shutdown.
The Fn-F4 key, that should switch the display mode, dosen't work. Other Fn keys work, however.

With Gutsy, it is like this:
With distributional X driver:
If the external monitor is plugged in during startup, it works, even Ubuntu startup logo is OK, until the graphical mode (GDM) is started. Then, blinking textual nonsense is displayed on the external monitor. Fn-F4 seems to switch to internal-only, then external-only. When both-monitors is enabled again, the image on internal LCD is garbled. Seems narrowed by 1/3 and overlayed on right side.
Interestingly, when the screen is blanked during inactivity, and then restored (e.q. by moving a mouse), the textual nonse on external monitor is greyscaled.
When rebooting, text mode is entered, so that external monitor can be read again, however if it faded to the greyscale before, the text is also grey, with limited visibility.
See pictures attached.
