On my system the X-Server isn't freezing but the flash video is freezing if I try a fast-forward. Setting EnableLinuxHWVideoDecode to 0 in /etc/adobe/mms.cfg will solve the problem for me too.
I'm using a GeForce 8600 GT with nvidia-current 295.20-0ubuntu1, adobe- flashplugin 11.1.102.63-0precise1 and xserver-xorg-core 2:1.11.4-0ubuntu5 on a 64 bit system. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/879978 Title: Xorg freeze on playin video in flashplugin To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/879978/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
