screen flashes
Last modified: 2010-07-18 16:59:41 UTC
I run Ubuntu 9.04 (Jaunty) 2.6.28-15 generic recently installed and wheneve I try to watch a movie on totem the screen flashes continually. This did not happen before upgrading from Ubunto 8.10
Are you using compiz or similar? If so, try disabling it.
Is there any option without disabling the compiz
We just need to know whether the flashing stops if you disable Compiz. You can re-enable if afterwards if you want, subject to further tests.

Go to System → Preferences → Appearance. Click on the "Visual Effects" tab and select the "none" option.

I have tried this and found that 'none' was already selected. I did try the 'normal' setting but got the message 'desktop appearance could not be changed'. I'd be grateful for any other suggestions.
what do you mean by "screen flashing"? If you had a screencast, or short explanation on how to reproduce the problem, it would be appreciated.
Don’t know if I see the same type of flashing or if it is separate. I first observed it during 2.30 cycle under Ubuntu Lucid. I get black dropouts on many keypresses that Totem reacts to like 0, 1, and 2 to scale or Ctrl-R and Ctrl-T. Also, upon clicking the title bar and switching workspaces. Hard to record screencast, only ffmpeg at 30 fps caught a number of dropouts. Has noisy audio. Didn’t intend to record it, but with it you can tell I’m pushing some buttons so I left it in. http://www.alice-dsl.net/~towolf/totem.mp4 (754k) - xvimagesink used. - Movie Player using GStreamer 0.10.28 - visible using both compiz and metacity (w/ composition off) $ xvinfo X-Video Extension version 2.2 screen #0 Adaptor #0: "Intel(R) Textured Video" number of ports: 16 port base: 80 operations supported: PutImage
