Refresh rate not being saved *RADEON HD 2400*

**astute** · May 25th, 2008

I am currently feeding my HDTV via HDMI from a Radeon HD 2400 graphics card. Using ubuntu 8.04 and proprietary fglrx drivers the HDTV is automatically recognised and Xorg generates the required modelines using EDID:

..........

The screen always defaults to 1920x1080 at 30Hz (interlaced) on startup. I have changed this value to 25Hz (PAL) using System-> Preferences->Screen Resolution and in the ATI Catalyst Control Center. Whilst this makes an immediate adjustment, on reboot the refresh rate always defaults to 30Hz. I have tried changing the "Modes" line in xorg.conf to "1920x1080_25" / "1920x1080@25" / "1920x1080"x25 to no effect, sometimes causing X to start in failsafe mode.

The 25Hz preference is stored in ~/.gnome2/monitors.xml, but seems to be doing nothing:

Code:

<configuration>
    <clone>no</clone>
    <output name="default">
        <vendor>???</vendor>
        <product>0x0000</product>
        <serial>0x00000000</serial>
        <width>1920</width>
        <height>1080</height>
        <rate>25</rate>
        <x>0</x>
        <y>0</y>
        <rotation>normal</rotation>
        <reflect_x>no</reflect_x>
        <reflect_y>no</reflect_y>
    </output>
</configuration>

Any suggestions gratefully received.
