Hi,
The question has troubled me very long. I don't know the where is the trouble. In
my thought,Xv driver belong to the
DDX layer of Xserver, and kde or gnome are the app(window manager) build upon Xserver.
Is it right?
If it's right, the Xv driver only connected directly with Xserver, and Xserver
communicates with window manager
as s/c. So the same Xv driver should have same effections when we use it at kde or
gnome. But I find that in Xv
driver, some methods of the offscreen video memory allocation is good when we use
gnome but they are very bad
when we use kde. At kde, the window manager may impropriate the video memory you has
allocated in Xv driver
temporarily or maybe they only have been exchanged( I can't make clear what happen,
but the desktop is dirty ). The
situations are very often when I used at virtual screen and only come out when I use
the capture. But they never come out
at gnome.
I have questioned the driver, but why the driver has different effects at gnome
and kde, maybe the problem is really at
the driver but why there are different effects? Do you meet this situation or give me
some advice? Thank you very much!
Regards,
Hzeng
