- Thanks to the great new Intel driver my external widescreen monitor Samsung
215tw with the native resolution 1680x1050 works fine out of the box after
system start.
- But if I start my laptop without the external monitor connected and plug it
afterwards it is recognized but the maximum resolution is 1280x1024 and the
default refresh rate 75 which is to high for my monitor. It is possible to
enable the monitor with [EMAIL PROTECTED] but it looks awful.
It seems that Xorg sets an Virtual size on start which is as high as the
needed resolution (x resolution value * x resolution value) but if a Display
with a higher resolution is connected it can only use resolutions which are the
same or lower than the virtual one.
There are two possible solutions imho.
Xorg should use the maximum virtual size if it doesn't need so much mem or
the better one: Xorg should be able to change the virtual size on the fly if a
monitor with a higher resolution is hotplugged.
