Thank for your replies, I had missed the rage3d forum. On this forum as on most sites compiling data for ati/linux, Radeon 7500 is not explicitly mentioned on the lists of supported hardware, however in a few places it is reported to work. Anyway the error I get clearly is not related to hardware.

I do load the glx module, here is my xorg.conf section:
Section 'Module'
Load 'ddc' # ddc probing of monitor
Load 'dbe'
Load 'dri'
Load 'extmod'
Load 'glx'
Load 'bitmap' # bitmap-fonts
Load 'type1'
Load 'freetype'
Load 'record'
EndSection

Actual results: GL falls back to using the 'swrast' driver. Expected results: GL is using the 'r300' driver. Additional info: - Issue has occurred intermittently during the F18 development cycle. Ok I tried to do everything to make my ati driver work,but simply I could not get it work. For couple days I hated freebsd. Now I decided to just use it without ati driver.

I found a couple of reports of this error msg, e.g. there:
http://lists.x.org/archives/xorg-modula … 00617.html
Invariably it was due to a wrong version of the libGL.so.
For me I have only one updated version of this file. Dc unlocker crack. However it happens to belong to ati-fglrx-utils 8.27.10-3. Since I replaced the 'fglrx' driver by 'radeon', I wonder whether there could be another version of libGL provided by another package that would be consistent with my radeon_dri.so ?
