hello,
my name is Dmitry Serpokryl and i'd highly appreciate if someone could
point me to the proper documentation about "How to set Xorg with several
proprietary drivers (ATI/nVidia) installed?"
right now the case is straight forward:
1) both "x11-video-fglrxG*" and "x11-video-nvidiaG*" packages contain
several duplicated files, so it's clear that they should be
repackaged/rebuilded anyway.
it could be a minor issue, but some of the duplicates are related to the
second point.
2) both "x11-video-fglrxG*" and "x11-video-nvidiaG*" packages place some
content into:
"/usr/lib*/xorg/modules/updates/"
and the case of this letter is the existence of:
"/usr/lib*/xorg/modules/updates/extensions/libglx.so"
which prevent (for example) the "AIGLX" for Intel cards and (according
to the "/usr/lib*/xorg/modules/updates/README.updates") there are no
"selection mechanism" capable to "match" the hardware with the
available drivers installed.
the question is:
"How to set the Xorg with mentioned proprietary drivers properly?"
in the end we should have the loaded "libGL.so" from "Mesa" for Intel
cards, from "x11-video-nvidiaG*" for NVIDIA and from "x11-video-fglrxG*"
for ATI, BUT! there should be some kind of a selection depending on the
"driver", because both (ATI and NVIDIA) could use the open source
solutions instead of proprietary ones.
right now i see only the way of an "ugly scripting" based on the output
from (and may be some other sane checks):
> lspci | grep -i vga
> grep -i driver /etc/X11/xorg.conf
which will set the "LD_PRELOAD=${LIBGL_SOLUTION}" with the optional
restart of the Xorg. this kind of a "solutions" we should use as a last
resort, because all games with the "LD_PRELOAD=" are definitely lead to
the wrong direction.
probably i should pick the disk of Ubuntu and look at their schema, but
it'd definitely prefer to follow the advises from this ML instead.
my apologizes for such a long letter.
regards,
sda
