4. Known Problems
- Known issues with this version of the SiS driver:
- The driver will not work with upcoming laptops/notebooks
with 661/741/760 and 30xLV bridges as regards LCD output. This
is due folks at SiS at the very moment writing an entirely new
VBIOS for such machines whose data layout is not decided yet.
(This might affect machines with 650/740 as well within the next
year.)
- Xv does not work correctly in TV NTSC 1024x768 mode, if
the overlay is very large (or full screen). The effect are
flickering lines on the screen. This is a hardware problem. Do
not use this mode for video.
- YPbPr 720p output is blurry (at least at 1024x768; unknown
for other modes). This is a driver problem; solution currently
unknown.
- We have received a late report that enabling DPMS support with
the radeon driver can damage some Viewsonic monitors. DPMS is usually
disabled by default. You can verify whether or not DPMS is enabled by
running 'xset q' from within your X session.
