 |
|
I have this nvidia intel optimus hardware thing in my laptop which works now with this software PRIME thing using DRI_PRIME=1.
The problem is, that I can't use a xorg.conf to activate this intel TearFree option which is deactivated by default since this xrandr provider offload thing doesn't work then.
Confusing? Yes - and annoying.
So is there a patch that enables this TearFree option by default for this intel driver?
Thanx for every hint. |

And the Intel doesn't have a separate xorg.conf? It does if you use Bumblebee.
Could you please elaborate how Prime works? |

I've spent too much time in this bumblebee thing and our friends from Arch say, that using nouveau means using PRIME thing, not bumblebee thing, and I WANT using nouveau since these proprietary nvidia drivers cause...
...right: Tearing.
I have no single idea what all these things do. I only follow slavishly this howto which says

Don't see both graphic adapters in xrandr --listproviders?
Delete xorg.conf! |
Wich I did and it works so we go back to this intel thing, which has to be patched but I really have no idea how to do this.
Perhaphs it has to do with these lines in configure.ac
| Code: | AC_ARG_ENABLE(tear-free,
AS_HELP_STRING([--enable-tear-free],
[Enable use of TearFree by default [default=no]]),
[TEARFREE="$enableval"],
[TEARFREE="no"])
if test "x$TEARFREE" = "xyes"; then
AC_DEFINE(TEARFREE,1,[Enable "TearFree" by default])
xp_msg="$xp_msg TearFree"
fi

but - as I've already written, I have no idea of these things... |

Edit:
This is the HOWTO I reffered to.
These guys from Arch are really hard-working in writing down secret knowledge and I hereby want to laud them for this.
And the good thing is: it often works  . In my case "Discrete Card as Primary GPU" does'nt work. Don't know why not, but as I formely said: concerning this PRIME thing I know less than nothing. It could have to do with my xserver version but this is just a guess from someone who knows...
...you know what.
I have a working version with these proprietary nvidia drivers which cause...
...you know that too. |
