Public bug reported:
Xubuntu since 6.06 (I believe..)
Graphics performance was never excellent, but o.k.
With 9.04 graphics performance is *poor*. Scrolling in Ooo-Files or PDF's is so
slow that I can see the single scrolling steps.
Switching desks is *slow* and hangs some times.
glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Mesa DRI Radeon 20061018 AGP 4x x86/MMX/SSE2
CPU usage is always down to almost 0%, so there are no processes slowing
the system down, as far as I can see. On scrolling / desk-switching it
jumps up to 100%. Compositor is off.
I am unsure if it is the same issue as reported with the INTEL-chips.
By the way: all information in xorg.conf has gone to some unspecified
location. Why not leave a note there like it was done in httpd.conf when
everything moved to apache2.conf?
