For historic reasons, if fglrx detects the compiz program, it falls back to
"indirect mode" OpenGL.
This fix works in combination with a soon to be released fglrx driver (version
latter than 8.84.60).
With this patch, Unity will work on systems with the fglrx driver.
Symptoms:
With a non-patched version of fglrx the following fails:
- running "compiz --replace" with the Unity plugin enable will fail at
startup.
- running "unity" also fails at startup.
Make a copy of the compiz binary (in /usr/bin) and name it "compiz-hack".
If you run "compiz-hack --replace" with the Unity plugin enable, then Unity
will not fail.
Evidences of fglrx working with this compiz patch:
- running "compiz --replace" with the Unity plugin enable should not fail
at startup.
- running "unity" should not fail at startup.
- The following examples in Nux should run:
gputests/texture_copy_blur
gputests/texture_blur
- auto-pilot reported PASS:
