I now found out that by changing TV_FORMAT the frequency gets changed, like it is supposed to, however the picture still stays b/w on my PAL tv.
xrandr --output TV --set TV_FORMAT NTSC-M --auto xrandr --verbose .... TV_FORMAT: NTSC-M .... 1024x768 (0x7e) 26.9MHz h: width 1024 start 1025 end 1088 total 1120 skew 0 clock 24.0KHz v: height 768 start 769 end 800 total 801 clock 30.0Hz xrandr --output TV --set TV_FORMAT PAL --auto xrandr --verbose .... TV_FORMAT: PAL .... 1024x768 (0x8a) 22.4MHz h: width 1024 start 1025 end 1088 total 1120 skew 0 clock 20.0KHz v: height 768 start 769 end 800 total 801 clock 25.0Hz -- Can't set TV_FORMAT anymore using xrandr https://bugs.launchpad.net/bugs/246802 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
