Description Fabio Erculiani (RETIRED) gentoo-dev 2009-09-20 06:31:30 UTC
** PLEASE **
Stop resetting OpenGL implementation to users, this is probably one of the epic bugs popping up so often. When changing OpenGL profile for build/compilation purposes, please remember to reset it back to user setting!

In xorg-server-1.6* (did not check previous ones) there is a function called "switch_opengl_implem" used in pkg_postinst:

- it does not seem to be used by something since after that there is only ewarn, ebeep and epause
- if it is required to switch to xorg-x11 opengl profile (for setting up symlinks for example), please consider to check for an already set implementation and then switch back to it
- consider the eselect opengl option "--use-old" if useful

I'm preparing a patch for these ebuilds

Reproducible: Always

After 2 hours, we've been able to figure out that it's NOT an ebuild nor Gentoo issue. Our apologies ;)
auto-killing myself.
