I've recently upgraded a machine with integrated Geforce4 MX video to 11.04 and now I can't change tv output format with nouveau.
xrandr --prop: Screen 0: minimum 320 x 200, current 800 x 600, maximum 4096 x 4096 VGA-1 disconnected (normal left inverted right x axis y axis) VGA-2 disconnected (normal left inverted right x axis y axis) DVI-D-1 disconnected (normal left inverted right x axis y axis) dithering: Off supported: Off On Automatic scaling mode: Full supported: None Full Center Full aspect TV-1 connected 800x600+0+0 (normal left inverted right x axis y axis) 0mm x 0mm overscan: 50 (0x00000032) range: (0,100) hue: 0 (0x00000000) range: (0,100) saturation: 50 (0x00000032) range: (0,100) flicker reduction: 50 (0x00000032) range: (0,100) mode: PAL supported: PAL PAL-M PAL-N PAL-Nc NTSC-M NTSC-J subconnector: SCART supported: Unknown Composite SVIDEO Component SCART select subconnector: Automatic supported: Automatic Composite SVIDEO Component SCART 720x576 50.0 + 1024x768 50.0 800x600 50.0* 720x480 50.0 640x480 50.0 400x300 100.0 320x240 100.0 320x200 100.0 Trying to set any of the non-numeric props triggers the reported error: xrandr --output TV-1 --set mode NTSC-M X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 150 (RANDR) Minor opcode of failed request: 13 (RRChangeOutputProperty) Value in failed request: 0x54 Serial number of failed request: 33 Current serial number in output stream: 34 The same error is reported for : xrandr --output TV-1 --set subconnector Composite >From the error it seems like it's expecting a numeric parameter for the mode prop, passing 0, 1, 2 and 3 return the same error. The numeric parameters work, like: xrandr --output TV-1 --set "flicker reduction" 100 After installing the xorg-edgers ppa the error is still present. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/738352 Title: xrandr S-video video mode not changeable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/738352/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
