    Need help improving visual quality


    Currently I am running KDE.

    I have truetype fonts installed, but many items appear fuzzy/slightly out of focus, even the truetype fonts.

    I have an LCD whose native resolution is 1280x1024. I used fglrx (kinda like xfree86, but for radeon drivers) to configure the display. I plugged in the appropriate frequencies listed in the manual that came with my monitor, and the display fits perfectly with 1280 x 1024 resolution. I suspect some of the visual problems may be from its refresh rate, which is SUPPOSED to be 60Hz. However, X windows says it is running at 75 Hz. The monitor can handle this, but I believe it would look better if I could change the refresh rate to 60 Hz while leaving the rest the same.

    Any idea how to do this?

    Thanks

    First, try it out by running "xrandr -r 60". That will set the refresh rate to 60 Hz for the current X session, but it will not be saved. It's good for trying it out, though.

    I got this in reply:

    X Error of failed request: BadValue (integer parameter out of range for operation)
    Major opcode of failed request: 157 (RANDR)
    Minor opcode of failed request: 2 (RRSetScreenConfig)
    Value in failed request: 0x3c
    Serial number of failed request: 12
    Current serial number in output stream: 12


    Interesting, eh?

    An amusing addendum:

    Although I DID have truetype fonts on my system, when I updated my video driver the newer XF86Config-4 file didn't have the path in it. I found this by thumbing through it trying to find a place that I could change it.

    Things look a lot better now, but still....fuzzy I guess you could say.

    What output do you get if you run only xrandr, without args?

    It seems that XFree86 is only configured to give you 75 Hz. Can you post the Monitor section from /etc/X11/XF86Config?

    I thought modern distros had abandoned XF86Config-4. Oh anyway, if you have XF86Config-4, then that's the one that is authoritative, so post from it.

    Sorry to frustrate you my friend

    XF86Config-4 was made by fglrx, which I need to run for my radeon driver.

    Here is the monitor section, although I could have sworn I posted it last night (hmmm....musta not hit submit)

    Is it my imagination or is every last line commented out?

    Thanks your help as usual.
