[mythtv-users] oversized screen resolution after upgrade from f8 to f10

[zablal baz]

Hey All,

Been searching through the forums and I don't see anything that quite
matches my problem.  If someone can point me at a thread or two where this
is discussed, I'd be grateful.

Everyone usually complains that their screen resolution is too low, but my
problem is reversed.  Under Fedora 8, my Nvidia card would run my Philips
47" LCD TV at XGA - 1024x768 at 60hz.  The manual for my TV confirms that this
should be the highest resolution when connected to a PC.  However, under
Fedora 10, with the same legacy driver (atrpms 96xx), xrandr shows the
screen resolution is set at 1280x720 at 50hz.

At first I thought to myself "well this is cool."  Then I noticed that this
effectively stretches out the desktop and display beyond the "borders" of
the screen.  I cannot access the menus or panels on my desktop, and it also
cuts off menu items in the setup utilities for mythtv.  I tried manually
forcing 1024x768 by making it the only mode in xorg.conf, but the nvidia
driver just ignores that and brings the display up in the higher resolution
anyway.  And xrandr does not even show 1024x768 as an option anymore.  I get
1280x720, followed by 800x600 and down.

On a side note: All of my videos are now stuttering and freezing when I play
them.  Could it be the two issues are related?


System specifics:
The nvidia card has a DVI port that uses a DVI-to-HDMI cable to connect to
an HDMI port on my TV.
