 Posted: Wed Jan 16, 2013 6:53 pm Post subject: Nvidia 3D acceleration - KDE 4.9.3 problems |
 |
|
After a global update, my NVIDIA Corporation G86 [GeForce 8400 GS] stop working properly. Not only acceleration is dead. I mixed up every configuration involving opengl until X start but KDE hangs up soon after load the desktop.
I touch EVERYTHING and sincerely don't know what is wrong.
I'm using the ebuild for proprietary drivers for nvidia and configure the kernel and xorg.conf following the Gentoo/Nvidia guide from the docs. I suspect from eselect options but I think I try every possible configuration. The results vary from X dying without start to KDE working with vesa, no acceleration, no desktop effects, mplayer unable to play 720p files.
The actual configurations from eselect are
| Code: | # eselect kernel list
Available kernel symlink targets:
..
[6] linux-3.5.7-gentoo * |
| Code: | # eselect mesa list
i915 (Intel 915, 945)
i965 (Intel 965, G/Q3x, G/Q4x)
r300 (Radeon R300-R500)
r600 (Radeon R600-R700, Evergreen, Northern Islands)
sw (Software renderer)
[1] classic *
[2] gallium

| Code: |
# eselect xvmc list
Available XvMC implementations ( * is current ):
[1] nvidia *

With this configurations I get the following Xorg.0.log errors

I'm desperate. Help please.

With the suggested configuration the X server don't even start.
Thanks anyway.
I don't know why mesa is installed. The Nvidia driver must replace the mesa implementation, doesn't?

Uups, then your proprietary doesn't load ?. Mine shows:
# lsmod|grep nvidia
nvidia 9371893 48
i2c_core 25551 2 nvidia,i2c_nforce2 |

You won't fix that by configuration probably, revert kernel to previous version ( remember to reemerge nvidia-drivers after each kernel update) and check if it is solved, then you can try with never kernel like 3.6.x ( or reemerge previous nvidia-drivers before global update if kernel revert wont fix it)
You can also check if you disabled in BIOS your first builtin card ( I suppose you have some intel ), if not then disable it totally.
ps. to check what u lately installed u can use qlop (from portage-utils):
qlop -lu | grep nvidia
qlop -lu | grep sources

I do fix it. But now I have more questions than before.
I change my USE= flags in the make.conf from this:
| Code: |
USE="qt4 kde dvd alsa cdr -gtk -gnome -introspection -semantic-desktop -dep -handbook"
|
to this:
| Code: |
USE="qt4 kde dvd alsa cdr sse sse2 sse3 3dfx ssse3 -vdpau opengl 3dnow mmx jpeg2k -gtk -gnome -introspection -semantic-desktop -dep -handbook"
|
And rebuild kdelibs, that from some reason haven't enabled opengl use flag by default. However, compiling mesa with vdpau flag (including opengl) mess the things up. I mean, with opengl and vdpau use flags enabled, rebuilding kdelibs doesn't solve the problems.
I can't find this in any tutorial but I think it should be. It's really a nasty, very hard to find and solve problem.

Pls precise your problem:
"Compiling mesa with vdpau flag (including opengl) mess the things up" - how it messes ?
"rebuilding kdelibs doesn't solve the problems" - what problems ?
There is some simple super short vdpau totorial -> http://wiki.gentoo.org/wiki/VDPAU

Sorry. My english isn't very good and maybe I couldn't explained myself very well.
The problem is the one described in the first post of this thread. X and KDE doesn't work with nvidia native drivers if you compile it (nvidida and kdelibs) with using the default use flags. However, using the opengl and -vdpau use flags, KDE works fine even with 3D acceleration from the driver.
In other words, the problem is solved, but I don't know why.
If you doesn't understand, please let me know and I will try it again.
