Change resolution on daytona borad.

[YongSung Yoon]

Guys,

I'm using QNX 6.1.0A on Daytona Board(XScale).
There is 'devg-cotulla.so' for graphics drivers.
Our daytona has 640 X 350 LCD screen.
And 'cotulla.conf' describe our screen properties like below.

I want to know how I can change screen to other resolution mode. (ex more
smaller resolution.)
Can I do it though changing contulla.conf ?
If so, is there anyone who teach me how I can ?

If not, Should I change 'devg-cotulla' driver ?
'devg-cotulla.so' is included in Xcale BSP on prebuilt binary.
Where I get the source code of 'devg-cotulla.so' ?

Any idea ?
