The flickering appears always for any pclk < 20, independent of screen resolution or refresh rate.
I could reproduce with 2 different boards: 945GME and 82945G/GZ. On the first one I had to add newmodes forcing the pclk >= 20 in order to avoid the flickering: xrandr --newmode "640x480_20" 20 640 664 720 800 480 483 487 500 xrandr --addmode TV1 "640x480_20" xrandr --output TV1 --mode 640x480_20 On the 82945G/GZ the flickering wasn't appearing in any resolution so I forced pclk <= 19.99 in order to get it flickering. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/480220 Title: [i945] [i945][karmic] S-Video: PAL output is garbled To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/480220/+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
