  • Radeon driver options?

    I was wondering if there is any documentation of some sort that lists all the various driver options one can utilise to adjust various driver options. Xorg.conf is used no more, but I have seen on occasions options such as radeon.dynpm=1 or something like that, which can be entered as a boot parameter to enable dynamic power management. I've also seen "vblank_mode=0 <program>" to disable vsync, or even "RADEON_HYPERZ=1 <program>" which can be entered into the terminal to enable HYPER Z for that specific program. Hence I was wondering if any one knows where to find a comprehensive list of such options, or if such documentation even exists or not.

    While the open source driver will work with little problems without an xorg.conf one can use one no problems (on Debian testing anyway. This is particularly usefull when using some weird configuration.

    I recently set up an xorg.conf on Radeon 3870 for a 20 inch monitor that did not send out the EDID data correctly to enable an 85hz refresh rate.

    For the driver options try the radeon manpage, "man radeon'

        Thank you to both Blacksmith and DanL. I had been aware of radeon manual but not for xorg.conf. Shall spend some time learning a few more things.
