Public bug reported:

Binary package hint: xserver-xorg-video-s3

This bug exists at least since 10.04 lucid, maybe earlier (have not
tested it before).

I am using the S3 savage driver for a S3 Savage/MX card on an HP XE3-GC
laptop. When playing videos (no matter which player as long as the Xv
acceleration is used), I encounter the following problem: whenever the
LCD is the primary screen (with its hardware resolution of 1024x768),
the video "input" width processed by Xv is limited by the ratio of the
actual resolution divided by the LCD hardware width (1024). If I set the
resolution to 800x600 for example (to be able to use the TV output in
full screen mode), I only can see 800/1024 = 0,78 of the real video
width, no matter if the video is displayed in a small player window or
enlarged to full screen. On the right of the video display, the
remaining width is filled with a black (or sometimes blue) bar. Using
s3switch to change the output to TV keeps this limitation, which makes
watching video on a TV or projector a pain!

If the CRT (external VGA out) is the main display (e.g. by using the
laptop in its docking station), I can change the resolution to whatever
I want and still have the full video width. Because of distances,
however, I could not yet check if the output transition CRT --> TV keeps
this full width also for the video output.

In any case, the xvinfo program does not show any limitation - but this
limitation should only concern the OUTPUT resolution anyway, not the
"source" width of the video being processed.

Xv / XVideo accelerated video width is limited by / depending on the screen resolution on S3 Savage, but only if the laptop LCD is the primary screen
