[SOLVED] RadeonHD 4830 with the radeonhd driver

It no workee.

I've got the following config working with the "ati" driver:

Section "Device"
        Identifier  "HD4830"
        Driver      "ati"
EndSection

Section "Screen"
        Identifier   "HD4830"
        Device       "HD4830"
        DefaultDepth     24
EndSection

Section "ServerLayout"
    Identifier    "Server"
    Screen        "HD4830"
EndSection

If I change "ati" to "radeonhd", X fails to start with (EE) No devices detected.  The odd thing is that, when failing, these lines show up in /var/log/Xorg.0.log:

(--) PCI:*(0@2:0:0) ATI Technologies Inc RV770 LE [Radeon HD 4800 Series] rev 0, Mem @ 0xd0000000/268435456, 0xfdce0000/65536, I/O @ 0x00009c00/256, BIOS @ 0x????????/131072
...
(II) Primary Device is: PCI 02@00:00:0
(EE) No devices detected.

This seems like a contradiction to me.

Google hasn't been much help, either pointed at the forums here or the web at large.  I've made sure all vestiges of catalyst are gone, I've power-cycled multiple times (the radeonhd manpage said that might be necessary) and X still fails to start.

Any ideas?

Odd. RV770 has been supported since 1.2.2: http://www.x.org/wiki/radeonhd
And Arch has 1.2.4. Unless RV770 LE is different? But I doubt it.

Oh, and BTW: http://www.bit-tech.net/news/hardware/2 … re-gimped/

Try making a new config with aticonfig, Xorg -configure, and hwd -xa.

Thanks.  I'm confused as to your suggestion to use aticonfig, though.  Isn't that tool specifically geared towards catalyst setups?

Also, I did some more digging and found this: http://article.gmane.org/gmane.comp.fre … eonhd/5513  The short version is that radeonhd 1.2.4 apparently doesn't recognize the 4830, though that's not quite how I interpreted the messages I saw.  I think I'll try applying that hack myself.

[ Edit: following the links to the bug report indicates that xf86-video-radeonhd-git should work; I'll try that instead. ]

Good find.

aticonfig might work, but you'd have to obviously change the Driver line to radeonhd. aticonfig sets lots of values to automatic settings, and I'm not sure whether they depend on fglrx to work. Maybe, maybe not, I don't have an AMD card. Since you found more info, you should probably be fine without this.

xf86-video-radeon-git confirmed to work.
