bottom and about a 1" band down both sides. It's connected via
HDMI to a 44" Samsung, as it has been for a couple of years.

I don't think it's a myth issue as the toolbar on the desktop
is the same way. It stops about an inch from the screen edges.
It seems to not know the tv/screen size anymore.
<br>
Ignoring the fact that it is not using the full screen the
aspect ratio is wrong, things are now squished top to bottom.

I don't understand what could have changed. This has been
working fine since I updated to v29 on Jan 1st. And on v0.28
for several months before that. I have not made any changes. I
did try rebooting several times and now it is always coming
back up like this.

Here is version info fixes/29 [v29.0-71-g339b08e]

There is a lot about waiting for video buffers and VDPAU

This log shows some errors about not being able to find
channel 4_1. I know that issue and I'll fix that.

This pc has an NVIDIA card in it and I'm wondering if the
driver has gotten corrupted. Not sure what to do about that.
<br>
<br>
Any suggestions?

What is the NVIDIA card and what is your linux kernel version ?
<br>
<br>
I recently had a problem on Xubuntu 16.04 LTS with an older
NVIDIA (Geforce 210) card caused by the the latest update
(Meltdown/Spectre) to kernel 4.13.0-26-generic
#29~16.04.2-Ubuntu SMP Tue Jan 9 22:00:44 UTC 2018 x86_64 x86_64
x86_64 GNU/Linux
<br>
which tries to install NVIDIA driver 384.111, the NVIDIA
install crashes. Previously I was using NVIDIA 340 driver.

That could be the problem. It is 16.04 (updated sometime in Dec)
and it is an older system going on 9 years old now.
<br>
The video card is ASUS GeForce 8400 GS DirectX 10 EN8400GS
SILENT/HTP/512M 512MB 64-Bit GDDR2 PCI Express x16 HDCP Ready

This is from dmesg - Linux version 4.13.0-26-generic
(buildd@lgw01-amd64-031) (gcc version 5.4.0 20160609 (Ubuntu
5.4.0-6ubuntu1~16.04.5)) #29~16.04.2-Ubuntu SMP Tue Jan 9 22:00:44
UTC 2018 (Ubuntu 4.13.0-26.29~16.04.2-generic 4.13.13)

How can I tell what driver it used to use and what driver it is
using now?

<p>From your pastebin you were using Nvidia 340.102, the 340 series
is the last to support your graphics card - it requires the Nvidia
legacy driver (later drivers do not support the graphics card).<br>
</p>
<p>The only solution I have found is to use the ubuntu graphics ppa
(which has 340.104 driver which has been patched to support latest
kernels) from
<a class="moz-txt-link-freetext" href="https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa">https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa</a></p>
<p>So from a terminal do :</p>
<pre class="command subordinate">sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt upgrade followed by a reboot.
</pre>
<p>Note Nvidia driver installation can be a bit problematic at
times, if this happens, I found the following usually fixes the
problem.</p>
<p>1. Purge the Nvidia drivers (sudo apt remove nvidia* --purge)</p>
<p>2. Reboot</p>
<p>3. Reinstall the Nvidia drivers , nvidia-340 in your case (sudo
apt install nvidia-340)</p>
<p>4. Reboot<br>
