Since upgrading to Karmic (Mythbuntu 9.10) my ATV is almost unusable. For the
first time in years, I am back to watching cable. Bah. A number of problems:1)
Video resolution is hosed. I output to a big screen projection TV (RCA MM52110)
using a component video cable. My TV doesn't have HDMI. It is a 4x3 screen.
When boot is finished and the desktop is showing, I have a small desktop in the
middle of the screen that is taller than it is wide. I use the nvidia settings
app and change the resolution to 1920x1080 and then the desktop more than fils
the screen. To be clear, that is what I had prior to upgrade. I never could
match the desktop size to the screen size. Unfortunately, it does not retain
the setings upon reboot. I adjusted xorg.conf, but no joy. I am using the 1.85
version of the nvidia driver. My other choice is 1.77. During the upgrade, I
believe that when i had an option, I used my existing version of config
files.2) Network is flaky, difficulty connecting to AP and when it does
connect, it SEEMS to be a poor connection.
3) VNC drops connection and then won't connect, maybe network related.If I can
get 1 and 3 fixed, I can keep troubleshooting. I have been working on this for
about 10 days with no joy. Has anyone sucessfully upgraded to Karmic and can
share their lessons learned? All this after Robert finally helped me get my
remote squared away. Thanks.

When my nvidia clocks were full speed I had those same symptoms.
However, it looks like your gpu and memory clocks are slowed down, 196
and 499 respectively. I run mine at 200 and 756. I use the following
to set all my nvidia related stuff.
These lines in /etc/modprobe.d/options.conf
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"
options nvidia NVreg_Mobile=0
These lines in /home/$user/.mythtv/session
#!/bin/sh
xset -dpms
xset s off
nvidia-settings -a GPUOverclockingState=1
nvidia-settings -a GPU2DClockFreqs=200,760
This line in the Device section of /etc/X11/xorg.conf
Option "RegistryDwords" "RMDisableRenderToSysmem=1"
These lines in the Screen section of /etc/X11/xorg.conf
Option "UseEvents" "1"
Option "NoLogo" "True"
Option "Coolbits" "1"
And this line in the Extensions section of /etc/X11/xorg.conf
Option "Composite" "Disable"
And running this to enable nvidia Xvmc
sed -i -e 's/^libXvMC.so.1$/libXvMCNVIDIA_dynamic.so.1/' /etc/X11/
XvMCConfig
I think that's all of my video related configuration items I use for
running Mythbuntu 9.04 with MythTV 21.
I hope that helps, but this could be a 22 issue. I have not tested
myth 22 frontends yet with the ATV(I'd mostly be worried about memory
usage with 22 and Mythbuntu 9.10). Although that is high up on my
priority list as there are some 22 backend features I'm looking to
implement in my setup.
