Video problems

[0pul3nce]

Hello can anyone help me...i've got flash videos in firefox that start glitching. I can never have two or more windows open without the glitching, sometimes i get it with just one video. (noticable when varying from small to large)

I've got a powerful system, which can cope when in vista..with numerous videos playing. So i'm confident hardware is not the issue.

I've done an update on my graphic driver to Nvidia 180.44

I've not found help in the forums i've read so far, and i think it's because i'm running Linux-x86_64.

Please advise me how to fix this bug.

Have you got the DVD playback packages installed (Section 4/5 of the link you posted)?

sudo apt-get install libdvdcss2 libdvdread4 libdvdnav4

Try running totem from the console to see if you get any error messages.

totem /path/toDVD/

I forgot there is another 'Vsync to Blank' to enable in Compiz, you will need to get 'compizconfig-settings-manager' from the repo then:
System > Preferences > Compiz Settings
General Options > Display Settings > Sync is at the bottom.

I redid the apt-get dvd stuff just in case. It now does play past the point it did so perhaps its fixed.

One final last hurdle and I'll be at the point where my windows machine was.
I thought everything was good until I restarted my computer and it loaded up all the display settings wrong. It doesn't want to start with the dvi-d as the default/primary monitor. So I have to take the analogue output which is normally plugged into the projector and plug it into the monitor. Then once I can see what I'm doing much jiggery-pokery and frustration occurs until I get it the way I wanted it only for it to forget everything next time I restart the comp. I've tried doing "Save to X Configuration File" but it gives the error "Unable to create new X config backup file '/etc/X11/xorg.conf.backup'." and the config doesn't seem to take as everything falls apart next restart.

"Save to X Configuration File" is the one in nvidia x server settings?

You need to be root to save to xorg.conf:

gksudo nvidia-settings

and your saved settings should stick.

do you ever feel that sometimes linux just takes the ****, just to annoy you? to answer every one of your solutions with a another problem? You've single handedly managed to fix all my problems to date but with each one has come another. The latest is that before iplayer played fine fullscreen, but now since changing the xorg.conf, it has become choppy fullscreen. it seems fine played normally in the window but it changes going fullscreen. avi videos and that play fine fullscreen as do dvds. but i cant see how i've changed things for iplayer

[Greenwidth]

I can't think why that would have changed flash playback.
Can you post your xorg.conf, and the backup for comparison.
The files are in /etc/X11/

If you:
sudo nvidia-settings (check Vsync in OPenGL section is ticked)
close settings
Try iPlayer again fullscreen any difference?

[Meuro]

I've tried putting iplayer on either screen but there is no improvement. (it should be noted that in twinview, the second screen has to be to the left of the first otherwise it will not fullscreen properly(http://ubuntuforums.org/showthread.php?p=7458326). So i tried the separate desktop thing and it switched round which was the primary monitor (ubuntu is forever trying to make the analogue output the primary and the dvi-d the secondary when i want it the other way round so i tried some poking about and editing of the conf which royally broked it) meaning I had to start again with a new xorg.conf and the problems remains. I've put the xorg.conf as it is now below just in case there is somehting in there to provide enlightenment.


i tried changing the OpenGL settings and there is no difference.

Theres nothing in there that I can see would be a problem, i've no experience with twinview though.

For the monitors swapping you could try adding to System > Preferences > Startup Applications (Add > paste into command)

nvidia-settings --load-config-only

For Flash add this to the end of your xorg.conf

Section "DRI"
	Mode 0666
EndSection

Section "Extensions"
	Option "Composite" "Enable"
EndSection

Both will need a restart (X or PC)

These may or may not be useful but beyond that I'm out of ideas..
