  • incorrect tv-out resolution on ati x1250

    Hi guys,
    I'm running on Ubuntu Lucid with radeon driver, the graphic cards works pretty well exception made from the fan always working (the smaller problem) and the tv-out resolution that is lower than expected for example 1024x768 ona 1440x900 lcd. I've tried it on several tv and with different vga cable, so I think it's not a device problem. I tried almost every xrandr command with no success. My question is: has one of you managed to make it works? should I try radeon hd driver? is there any hope to get it working?
    thanks!

    I doubt that radeonhd would make a difference.

    Can you provide the Xorg.0.log? There may be helpful information inside.

        The driver isn't able to get an edid from your monitor for some reason. check your dmesg.

            How are connecting your tv to your computer? S-video or VGA? There is no EDID when using S-video and you are limited to 1024x768.

            According to your log:
            (II) RADEON(0): Output VGA-0 connected
            (II) RADEON(0): Output LVDS connected
            (II) RADEON(0): Output S-video disconnected
            (II) RADEON(0): Using fuzzy aspect match for initial modes
            (II) RADEON(0): Output VGA-0 using initial mode 1024x768
            (II) RADEON(0): Output LVDS using initial mode 1024x768

            Only the LVDS and VGA ports are connected. The VGA port has no EDID so it defaults to 1024x768.

                If you are sure the monitor can support it, you can manually add the modeline you want if the driver is not able to get the edid from the monitor. E.g.,

                xrandr --newmode 1440x900 88.75 1440 1488 1520 1600 900 903 909 926 +hsync -vsync
                xrandr --addmode VGA-0 1440x900
                xrandr --output VGA-0 --mode 1440x900

                  thanks for the ad
                  Now the resolution option (1440x900) is aviable but when I try to enable it the monitor doesn't show nothing....

                  here is the updated dmesg

                  in the meanwhile thanks for the patience (also for reading my bad english )

                      here is the xandr output

                      Code:
                      jumba@jumba-laptop:~$ xrandr --verbose --output VGA-0 --mode 1440x900
                      screen 0: 2640x900 699x238 mm  95.85dpi
                      crtc 0:     1440x900   59.4 +0+0 "VGA-0"
                      obviously the screen was still black...
