[PATCH] nvidiafb: Fix initial display corruption on certain laptops
Reported by:Vincent Fortier (Bugzilla Bug 4768)
"At boot time the screen appears moved to the mid right portion of the actual
video pannel making the end of the line appears at the left edge... It simply
looks like moved half way to the right"
His particular hardware has a display with an unusual dimension (1920x1200) but
unfortunately has no EDID block. None of the entries in the global mode
database is correct for this particular display, and it particularly has
difficulty scaling up 640x480 (the default startup mode of nvidiafb) to
1920x1200 which causes the above described problem.
1, Add 1920x1200 to the global mode database.
2. Let nvidiafb base the startup mode from the flatpanel dimensions only if the
EDID block is absent, no boot mode parameter is specified by the user, and
a flatpanel/LCD display is attached.
