Ubuntu 11.10

[idragosani]

I upgraded my Linux installation to Ubuntu Studio 11.10 tonight (64-bit).

TVP Animation 9.5.20 runs on this version, however, it takes a loooooong time to start up, several minutes, in fact.

I did an strace against the running process and this is what I see for many iterations:

ioctl(6, VIDIOC_G_FMT or VT_SENDSIG, 0x7fff7c328430) = 0
ioctl(6, VIDIOC_S_FMT or VT_RELDISP, 0x7fff7c328430) = -1 EIO (Input/output error)
ioctl(6, VIDIOC_G_FMT or VT_SENDSIG, 0x7fff7c328430) = 0
ioctl(6, VIDIOC_S_FMT or VT_RELDISP, 0x7fff7c328430) = -1 EIO (Input/output error)
ioctl(6, VIDIOC_G_FMT or VT_SENDSIG, 0x7fff7c328430) = 0
ioctl(6, VIDIOC_S_FMT or VT_RELDISP, 0x7fff7c328430) = -1 EIO (Input/output error)
ioctl(6, VIDIOC_G_FMT or VT_SENDSIG, 0x7fff7c328430) = 0
ioctl(6, VIDIOC_S_FMT or VT_RELDISP, 0x7fff7c328430) = -1 EIO (Input/output error)
ioctl(6, VIDIOC_G_FMT or VT_SENDSIG, 0x7fff7c328430) = 0
ioctl(6, VIDIOC_S_FMT or VT_RELDISP, 0x7fff7c328430) = -1 EIO (Input/output error)
ioctl(6, VIDIOC_G_FMT or VT_SENDSIG, 0x7fff7c328430) = 0
ioctl(6, VIDIOC_S_FMT or VT_RELDISP, 0x7fff7c328430) = -1 EIO (Input/output error)
ioctl(6, VIDIOC_G_FMT or VT_SENDSIG, 0x7fff7c328430) = 0
ioctl(6, VIDIOC_S_FMT or VT_RELDISP, 0x7fff7c328430) = -1 EIO (Input/output error)
ioctl(6, VIDIOC_G_FMT or VT_SENDSIG, 0x7fff7c328430) = 0

and then once it does come up, I see this in the console:

select(1024, [6 7], NULL, NULL, {0, 16700}) = 0 (Timeout)
read(6, 0x2182754, 4096) = -1 EAGAIN (Resource temporarily unavailable)

Let me know if there is anything else I can provide to help diagnose this

Can you please, try to start TVPaint without your webcam. And see if it starts more quickly and if you still have these messages.

Wow, TVPA started instantaneously with the webcam unattached.

I still see these from the strace:

read(6, 0x2182754, 4096) = -1 EAGAIN (Resource temporarily unavailable)

[Eric Scholl]

I don't know what it could be for the second error message. I am upgrading my ubuntu right now to see if I can get the same errors.

Everything else seems to be working OK now. Thanks!

[Eric Scholl]

Everything seems to be ok here. TVPaint starts quikly and without error message, even with the camera.

Try to update your ubuntu, reboot and reinstall TVPaint. It's the only things I can say for now.

I had done a re-installation of TVPA already. Something is screwy with the webcam (Logitech HD camera, don't remember the model number), maybe a flaky kernel driver or something. Without the webcam plugged in, I think TVPA starts up even faster now than in the previous version.

Edit: the error messages don't appear under normal usage, just when I used strace to trace system calls call by the process.

[Eric Scholl]

Yeah, it seems that TVPaint starts really faster in Ubuntu 11.10 than in 11.04

Is the webcam available in TVPaint when it's started ? (it need to be plugged in before starting TVPaint).

I didn't check to see if the webcam is available inside TVPaint. I don't use it with TVPA anyway so not having it available isn't an issue at all. I'll continue investigating tonight and see if I can figure out why the camera is causing a problem.

Interesting, Eric... I reattached the webcam after I got home today and the problem has gone away! TVP started right up, and the camera is available without any issues inside TVP (I can even capture HD images through the camera). Maybe reattaching the camera re-initialized the driver correctly.

[Eric Scholl]

I'm happy to see that the problem is resolved

I tried update to 11.10 few days ago and it was absolutely worse.

I think 10.10 contains too many bugs now. Wait a month before update is a good way.

[idragosani]

I ended up reverting back to 11.04 for a variety of reasons, everything is working together much better
