The screen preview is *NOT* a snapshot of the screen. The screen preview already is a few very small pixmap images. It is the same code that Xconfigurator used to use called "Xtest", which has had the graphics updated to look like the modern desktop. Unless something was changed that I'm not aware of. Brent? If that's true then you folks managed to choose images that always look exactly like whatever my desktop looks like. Seriously, though, redhat-config-xfree86 has (since I first tried it in the pre-8.0 betas) always used the local desktop for the preview. I just tried it on a work machine across a cable modem (2.5Mbps down, .5Mbps up) and it took six minutes for the initial window to appear, during which time my desktop was useless. The cursor would move but windows would not update their contents, the focus would not change, etc. I just don't think anyone envisioned a sysadmin running this application remotely, especially across a slow link. (Really, I pine for an interactive text-mode application to do this, but someone's already filed that enhancement request.) /usr/X11R6/share/Xtest/pixmaps/desktop_icons.png /usr/X11R6/share/Xtest/pixmaps/panel_left.png /usr/X11R6/share/Xtest/pixmaps/panel_mid.png /usr/X11R6/share/Xtest/pixmaps/panel_right.png I'm not sure that the application is designed nor intended to be ran remotely. Brent will have to comment on that. redhat-config-xfree86 does take a snapshot of the current desktop in order to draw the preview screen. Alex originally wrote the program, so it's hard for me to say what exactly he had in mind. My guess is that he assumed that the tool would be run on the local machine. I'm not surprised that there might be some strange behavior by running it remotely. I agree that the behavior is a little strange, but I'm not sure it's bad enough to warrant fixing. Over a high speed network connection, it seems to run pretty fast. I think that using pretty much any X application of any complexity over a remote link is going to be pretty darn slow over a slow connection. |
