Title:
Unity/compiz fails to load on Intel i865 IGP (OGL 1.3) in 13.04 and
13.10, mesa/unity_support_test is incorrect
Status in “unity” package in Ubuntu:
Confirmed
Bug description:
When I log into a desktop session in Ubuntu 13.04 and 13.10 (both the
Live CD and a fresh install), the top panel and launcher both seem to
completely fail to load.
When viewing console output via one of the virtual terminals, I can
see that compiz is failing to load the OpenGL plugin.
compiz (core) - Error: Plugin 'opengl' not loaded.
Right-clicking on the wallpaper still brings up the right-click menu
as expected, but performance is extremely slow.
I am using an Intel i865 IGP (82865G), which supports the OpenGL 1.3
standard. This appears to be where the bug lies.
unity_support_test gives an incorrect report of the IGP, stating that
it supports OpenGL 1.4. This was not the case with Ubuntu 12.10, the
last Ubuntu release where Unity worked on this computer.
Ubuntu 12.10's unity_support_test yields the correct test result (GL
version is 1.4+: no), while 13.04 and 13.10's yields an incorrect test
result (GL version is 1.4+: yes).
Could potentially be an issue with the version of mesa included with
13.04 and 13.10.
Ubuntu Version: Ubuntu 13.04, 13.10 i386
What is expected to happen: Unity loads, unity_support_test returns "GL
version is 1.4+: no"
What happened instead: Unity does not load, compiz fails to load opengl
plugin, unity_support_test returns "GL version is 1.4: yes"
IGP/GPU: Intel Extreme Graphics 2 82865G (i865 chipset)
