unable to load driver: r200_dri.so

**Thaidog** · 02-18-2009, 08:16 AM

I am trying to get direct rendering working on my system with an ATI 9000 Pro 128Mb card but it looks like the correct driver is not on the system:

unable to load driver: r200_dri.so

gentoo_icc tylerm # LIBGL_DEBUG=verbose glxinfo | grep rendering
libGL: XF86DRIGetClientDriverName: 5.3.0 r200 (screen 0)
libGL: OpenDriver: trying /usr/lib/dri/tls/r200_dri.so
libGL: OpenDriver: trying /usr/lib/dri/r200_dri.so
libGL error: dlopen /usr/lib/dri/r200_dri.so failed (/usr/lib/dri/r200_dri.so: cannot open shared object file: No such file or directory)
libGL error: unable to load driver: r200_dri.so

gentoo_icc tylerm # locate r200_dri.so
gentoo_icc tylerm #

I installed the xf86-video-ati driver.

lspci -v looks like this:

r200_dri.so is the 3D driver and it's separate from xf86-video-ati. xf86-video-ati provides card setup and 2d/video accel for all radeons. 3D accel is handled by a separate 3D driver. You'll need to install mesa or the libgl1-mesa-dri package for your distro.

It appears that the mesa package is already installed:

I do have some r300 stuff though:

gentoo_icc tylerm # locate r300
/usr/src/linux-2.6.27-gentoo-r8/drivers/gpu/drm/radeon/r300_cmdbuf.c
/usr/src/linux-2.6.27-gentoo-r8/drivers/gpu/drm/radeon/r300_reg.h
/usr/src/linux-2.6.27-gentoo-r8/drivers/gpu/drm/radeon/.r300_cmdbuf.o.cmd

/usr/include/drm/r300_reg.h

Ok i found iout the problem but I stil have not resoved the issue. This page at the bottom describes the issue:

http://www.mobygeek.net/blog/category/gentoo/

I did not have /usr/lib/drm directory so I made it and then make a symlink:

gentoo_icc dri # ls
r200_dri.so
gentoo_icc dri # ls -l
total 0
lrwxrwxrwx 1 root root 43 Feb 18 10:44 r200_dri.so -> /usr/lib/xorg/modules/drivers/radeon_drv.so

But I still am missing something:

gentoo_icc tylerm # LIBGL_DEBUG=verbose glxinfo | grep render
libGL: XF86DRIGetClientDriverName: 5.3.0 r200 (screen 0)
libGL: OpenDriver: trying /usr/lib/dri/tls/r200_dri.so

Well, like the error says, you're missing r200_dri.so, which is the DRI driver for the r200 chips. I'm not sure what package that belongs to in gentoo, but it should be libgl-dri, or something like that.

**tomciaaa** · 04-07-2009, 01:14 AM

Just that others googling up to this thread know: installing media-libs/mesa is of no use if "radeon" use flag is not set. This could happen if you tried to use "flgrx" but later decided to switch. Then mesa is not recompiled and most likely you WILL NEED to issue:

emerge -va media-libs/mesa

Hope that helps some of you, because I spent an hour figuring this one out.

You should also upgrade from mesa-6.5.2. It's _quite_ old.
