I have 60" Mitsubishi TV connected to the HDMI output of
a home-brew box running MythTV on Fedora 17. I have not been
able to do any updates lately for fear of losing the one
kernel that can see the Mitsubishi.
When I boot into 3.5.3-1, it works - I get the Fedora (Gnome)
desktop on my TV connected to the HDMI output.
When I boot into 3.6.10-2, it doesn't see the TV. I can hook
up a smaller monitor to the VGA output, and that works. When
I start System Settings / Display -> Detect Monitors it only
detects the VGA monitor.
The two cases are otherwise the same - the difference is just
kernel I select in the Grub screen. I don't dare to update
Fedora (at least not the kernel), because then I'll lose the
one working kernel.
I also booted up the F18 Live disk (KDE). Same deal: I get a
desktop on the VGA monitor, but nothing on the TV.
Also, the newer kernels don't seem to detect the correct
resolutions on the (admittedly old) VGA monitor.
I also tried replacing with TV with 27" monitor, also
connected to HDMI - same result: 3.5.3-1; 3.6.10-2 doesn't.
Does this ring a bell with anyone? I do have Xorg.0.log
and /var/log/messages copied from a non-working setup.
What video card? Which video driver?
I have F18, latest updates, with an Nvidia card and Nvidia
driver working with HDMI output, video and sound.
