help from ATI RADEON_HD users
 
Dear fellows,

My F11 was working fine with radeon_hd driver until last week.
Today I notice the rendering of images on display sucks, you known, tooooo slow...

Searching for errors on Xorg.0.log I found:
Code:

(EE) AIGLX error: dlopen of /usr/lib64/dri/r600_dri.so failed (/usr/lib64/dri/r600_dri.so: cannot open shared object file: No such file or directory)
(EE) AIGLX: reverting to software rendering

so, the "software rendering" above explains why it is slow.

What I don't known is what happened to file "/usr/lib64/dri/r600_dri.so". In fact it is not there !

I don't known what is the package this file belongs to.
If I figure out what package is I can re-install it. Anyone knows ?

I try to force a re-install of some related packages, but no luck:
Code:

yum reinstall mesa-dri-drivers mesa-libGL xorg-x11-drv-radeonhd
Another strange thing is there is no evidence of any missing files on my system:
Code:

for pkg in $(rpm -qa); do
  rpm -qV "${pkg}" | grep -q missing
  if [ "$?" = "0" ]; then
    echo "missing file on package ${pkg}";
    rpm -qV "${pkg}" | grep missing
  fi
done

The above code returns nothing....

Well, I guess the simplest way to fix this is to re-install the associated package that "r600_dri.so" belongs to. So, please, if anyone could help me by given me the output of "rpm -qf /usr/lib64/dri/r600_dri.so" (or "rpm -qf /usr/lib/dri/r600_dri.so" if you have a 32 bits system) I appreciate very much.

best regards,

Use a xorg.conf file and adjusts options or try radeon.

Which card?

Ignore that error (of missing .so) ... there is no such 3D driver for r6xx/7xx

Hi Amani,

I was using radeon_hd driver (xorg-x11-drv-radeonhd) until something broke. Now, to get at least a decent 2D performance I switched to radeon (not hd) and removed /etc/x11/xorg.conf letting X to use defaults. No 3D effects....

I don't known exactly what happened here, because I am not the only one who has the root password for this machine and I didn't setup the 3D on this machine.

Are you sure there is no 3D driver for RV670PRO (Radeon HD 3850) ?

But, for sure, this machine was running 3D acceleration and openGL programs (and compiz) are working just fine....I was playing the World Of Goo demo until 2 weeks ago...(www.worldofgoo.com, nice, it is for linux, try it)

And what about the missing file ? If the file was not supposed to be there, them what ? It is a bug ?

Missing file... there was a discussion on this at phoronix forums. It is still in development and can be safely ignored. There are detailed instructions for trying the latest development stuff.

fglrx will not work in F11.
