Was there an upgrade of nvidia-glx or the kernel? Also, do you use the
nvidia-* packages from non-free, or have you run Nvidia's installer?
Its the nvidia-* packages from non-free
Looking at my Xorg.0.log file, it appears that the nv driver is being

This is pretty normal, although you should specify the nvidia driver in
/etc/X11/xorg.conf, preventing all the probing of other drivers in the
first place. Do you even have an xorg.conf?
No xorg.conf, so its doing it automatically.
I am not worried about all the probing etc - unless it gets the wrong
answer. This is in essence a headless server which runs 24/7 so hardly
ever restarts. I have gdm3 start up and automatically start and restart
if it exits) mythwelcome, which just sits there on the "console" - which
effectively acts as my local TV screen. Its only used to run
mythtv-frontend.
(EE) Failed to initialize GLX extension (Compatible NVIDIA X driver

You will not be able to run OpenGL programs.
No matter - although I don't think it failed before.
I have the following in /etc/modprobe.d/nvidia-kernel-common.conf
alias char-major-195* nvidia
options nvidia NVreg_DeviceFileUID=0 NVreg_DeviceFileGID=44
NVreg_DeviceFileMode=0660
# To enable FastWrites and Sidebus addressing, uncomment these lines
# options nvidia NVreg_EnableAGPSBA=1
# options nvidia NVreg_EnableAGPFW=1
# see #580894
blacklist nouveau
Which I seem to remember was a previous attempt to ensure the nouveau
driver didn't load. However an lsmod definitely shows it to be there.
Blacklisting a kernel module only ensures that udev won't load it
(because it runs modprobe with the "-b" switch). It does not prevent
loading the module by other means (such as by the X server, who runs
modprobe _without_ the "-b" switch).
Does this mean that I really ought to make an xorg.conf ?
