i've been dealing with this for a good while and had a nice kludge that seemed to work, even if it was a bit odd, but somehow after a power outage last night, even my kludge doesn't work.

i'm not sure if there's some bit of instruction that i missed in setting up my nvidia card or if i've just got some odd sort of junker of a card, but after getting everything set up, my tvout would only function after booting with the 'nv' driver, then recompiling nvidia, changing my XF86Config-4 to point to my custom config file (using the 'nviida' module), and restarting gdm. i had actually written a script for this so that i could ssh to the box and just su to root, run the script and have TVout working just fine. now nothing works. i get no picture using Svideo or my SVID->RCA adapter. i get a console up until X starts at which time i get nothing, with either the nv or nvidia module running it.

if anyone has seen this problem and knows of an anwswer, i'd be much appreciative of advice/assistance/help that could be offered. i'd LOVE to have it working the way it's advertised (i.e., nvidia TVout works when it comes up with no external interference from me...). on the other hand, i'd settle for having my kludge being functional again.

my (formerly working) kludge is as follows:
Code:
mythtv@mythtv:~$ cat nvidia.sh
#!/bin/bash
#
# ugly kludge to make our nvidia driver work properly on boot
#

# the nvidia script will not be able to rmmod the nvidia module if it is still loaded, so we want to ln to our old nv config, then restart X to make the nvidia module unused
ln -sf /etc/X11/XF86Config-4.old /etc/X11/XF86Config-4
/etc/init.d/gdm restart

#the nvidia script automatically overwrites (!!!) whatever is linked to /etc/X11/XF86Config-4 with it's idea of what you should have, so we need to re-link that file before we let the nvidia driver do anything...
ln -sf /etc/X11/foo /etc/X11/XF86Config-4

# install the nvidia driver (again!)
install-nvidia-6629-debian.sh

# the above script automatically restarts gdm, but we need to change our XF86XConfig-4 to use our nvidia version with proper parameters...
ln -sf /etc/X11/XF86Config-4.my_nvidia /etc/X11/XF86Config-4

# restart gdm (again!) to use the new config
/etc/init.d/gdm restart


oh yeah, i forgot to mention that i've tried both the 6629 and the 7174 versions of the nvidia driver now.

well, after looking through a few other peoples XF86Config-4s, i made a few adjustments to the one that i was using, first try was a no-go, second try was a no-go and i noticed that my XF86Config-4 symlink was pointing to the wrong file in the first place, so i went back and made the original changes again (as in the first try), and tried to rebuild the module and run it, and it wouldn't due to the nvidia driver being loaded.

so, i re-symlinked to the config using the nv module, rebooted (only way i can convince the nvidia module to unload itself), and tried it again. cha-ching, after running my kludge script, i have a TV cloning whats displayed on the monitor (which has now been removed). i'm unsure if it will work again on reboot, and since the A&M game is on tonight, i'll stand by the old adage "if it ain't broke, don't fix it.". at least for tonight, anyhow. i'll try a reboot in the morning and update this thread with the results, as well as my currently working XF86Config-4.

after the reboot i've found that my config will not work when only the TV is hooked up, i get a black screen and thats it. i think it might need to have a monitor hooked up, then reboot and run my kludge script. this, however, is completely unacceptable for a computer thats supposed to sit in the living room with it's only human-interactions being with a remote control and a DVD-ROM drive...

heading to test my monitor-attached theory...
