      I have the correct version of libdrm:
      Code:
      $ nm -D /usr/lib/libdrm.so.2.4.0 | grep Fd
      00000000000032c0 T drmGetDeviceNameFromFd
      but xf86-video-ati still refuses to install in gentoo:
      Code:
        CC    radeon_dri2.o
      radeon_dri2.c: In function ‘radeon_dri2_screen_init’:
      radeon_dri2.c:339: warning: implicit declaration of function ‘drmGetDeviceNameFromFd’
      radeon_dri2.c:339: warning: assignment makes pointer from integer without a cast
      It might work if xf86drm.h was actually included in radeon_dri2.c.

        Your build is not finding the proper libdrm. xf86drm.h is included in radeon.h

          And in fglrx ?

          Thanks
          oh yes... in radeon you have working Xv in fglrx its broken!

          only openGL viedeo rendering works Good in FGLRX...

          at fglrx you have openGL3+ but,, its broken some extansions effektet in wine are broken... fglrx is broken at openGL...

          i think catalyst 9.12 will fix this problem because of openGL3.2 and the special wine openGL exstansions.

          at radeon+kms+openGL2 its broken to yes its broken but amd tells fglrx stable and radeon openGL2 is only an experimental unstable feature-test..

          overall you can use openGL1,5 with radeon and good openGL2.1 with fglrx or in the near future openGL3.2... OpenGL3.0 and openGL3.1 are not realy usefull.

          radeon have DRI2 fglrx only dri..

          radeon have KMS fglrx does not have KMS

          radeon do not have flash viedeo acceleration.. fglrx have viedeo acceleration..

          radeon have EAX Desktop Acceleration FGLRX only have XAA acceleration

          Radeon have working Compiz fglrx has (2sec bug)lags and in my test crashes.



          so you have the Choice between Cancer and Influenza...

            You're right. I don't know how, but I had an ancient libdrm in /usr/local. Sorry for the noise.

              Using sidux (2.6.32 kernel and Xserver 1.6.5 ATM), everything built properly. I stopped kdm and went into TTY1, reloaded the modules and was greeted with the console at native resolution. No errors in dmesg. So far, so good.

              Tried to start kdm, and was greeted with a very garbled screen. Everything looks good in Xorg log:

                >radeon have DRI2 fglrx only dri..

                you can't really compare them.

                  Right. The fglrx driver does not use the DRI2 protocol but provides most of the same benefits, including Redirected Direct Rendering.

                    I have tried to use KMS on x700 but as i didn't want to build git releases i used http://ppa.launchpad.net/xorg-edgers/ubuntu/ as a software source and did all updates from it with kpakckagekit.

                    How surprised i have been when I saw it working out of the box after the update (a rebot later of course). It's not the most important feature but it's still great.

                    I have noticed a few problems tough.
                    If you try to switch to a tty during kde loading, coming back to X will give you a broken kde with only a gnombe background : no taskbar or anything. I have killed X to restart kdm and not to switch during kde load. Kde started correctly but I was unable to launch kde apps. I rebooted and it was fixed.

                    One other thing : booting without radeon.modeset=1 willnot work. X tries to start and crashes instantly.

                    Thanks for the good work on this driver.
