This is getting weird. I haven't rebooted in a few weeks now. I tried
to watch a video a bit ago and it was slow again. It was down to about
2 or 3 frames per second. It is awful. If I go tell it to switch to
opengl, it gets fast again but after a while it will go back to being
really slow. Why do I have to keep telling it to use nvidia's opengl
when it says it is using it and I have switched to a few times? If it
is using it, why does it slow down until I tell it to switch?
I did do a huge KDE upgrade the other day. I don't recall seeing
anything else X related being updated but I could have missed something
in that LONG list. I did do a baselayout upgrade and portage itself has
been upgraded a few times.
Any ideas on why this thing keeps doing this? Would a reboot even help
in this situation?
When it gets very slow start up top and see what's using the CPU. My bet is
the Xserver. I have a GeForce 9400 GT 512MB and the xserver will happily use
90% while nothing much is happening. Start a KDE4 app which constantly updates
(ktorrent, kps are good 3rd party examples) and the xserver goes crazy.

Nope, it wasn't that here. This is what top says:

It was glxgears that was taking up the most CPU time but I think the
rest of it was processing the video. Thing is, nothing has been updated
and I have not even logged out of KDE since it was working this
morning. So, without me doing a single thing, it has stopped working as
it should. It's like the card is being bypassed as far as it using its
own CPU to process the picture.
Oh, look at this miserable mess:
2 frames in 8.5 seconds = 0.236 FPS
2 frames in 8.7 seconds = 0.230 FPS
2 frames in 8.3 seconds = 0.241 FPS
2 frames in 8.1 seconds = 0.246 FPS
2 frames in 8.1 seconds = 0.247 FPS
2 frames in 8.1 seconds = 0.247 FPS
2 frames in 8.3 seconds = 0.241 FPS
Trust me, to see those little wheels turn that slow is really boring.
Going back to single user and switch this again. I have noticed that
telling it to switch to nvidia's opengl while in single user mode does
seem to last longer. Going to re-emerge the drivers to while I am at
it. Can't hurt anything.
Still open to ideas cause this is weird.
