XGL and NVIDIA

those things are normally not hardcoded , but added by the configure script , as it finds the current libstdc++ or compiler setting to be 4.02.

thats why i asked , if you checked all this, then probably it *IS* hardcoded - then you can search the code for it and replace it with the Var.

I dont think it is hardcoded because not alle ppl have 4.0.2 - i for example compiled it with 4.1.....

Hi,

I've got a "nVidia GeForce4 420 Go 32M".
Is it "normal" to get black windows with this card or is it a solution to solve this problem?

ok I've got everything compiled and installed but when i run the command "Xgl :1 -ac -accel glx:pbuffer -accel xv" i get the following:

before you ask, yes, opengl is working just fine in X so that cant be it.

It's working! I used Hanno's xgl-overlay-200602120.tar.bz2 and followed the wiki

Negative symptoms:
1. KDE runs slow on Xgl. I hope it's not because of gnome-window-decorator. Gnome runs fine. I'll try turning off some plugins. At least KDE runs, about a week ago KDE would crash Xgl.
2. Wobbly jerkiness. With wobbly, when I drag a window it starts wobbling, but if I stop moving the mouse the wobbly effect pauses leaving the window frozen in whatever distorted shape until I start moving the mouse again or stop holding down the mouse button. When I let go of the window, the wobbly effect stutters as it subsides. About a week ago the wobbly effect used to continue smoothly (even when the mouse isn't moving) and without stuttering.
3. Doom3 segfaults :-(

...and ppracer says "Couldn't find matching GLX visual". glxgears seems to be the only opengl app I can run.
4. xine-ui's UI window is garbled and video playback works, but with weird colored shadows. xine-ui's right-click menu crashes gnome-window-decorator

Positive:
1. No black windows.
2. glxgears gives double fps in Xgl!!! (3000 -> 6000) This is too good to be true, maybe Xgl is defaulting to 16 bit color or something like that.

Relevant specs:
GCC 4.1 beta 20060203
CFLAGS="-march=athlon-xp -mtune=athlon-xp -O2 -pipe -fomit-frame-pointer -fno-ident"
GeForce FX 5700
nvidia-kernel and nvidia-glx version 1.0.8178
hanno's overlay included two mesa ebuilds, I used the mesa-6.4.2-r1ebuild instead of unmasking the 6.4.3_alpha one.

My 5600xt only stutters a little when I let go of the wobbly window.
I don't run KDE but gnome runs fine.

glxgears goes from 1200 to 1900

I'm getting great results. I don't use DE's like Gnome but I have been testing with just compiz and urxvt and everything seems to work.
Check the end of the other thread (XGL Part 2) for fixes for the undefined symbol.

I am on a 6600GT and my glxgears went from 6000 to around 10000.

Is it just me or is xgl consideribly SLOWER then xorg 7?

I know it's a bad benchmark, but glxgears goes from ~4700 to ~2400 fps. This is on a Geforce 6600 with 256 megs. I always thought 4700 fps was low, but with xgl, it's even worse.

I'm also not getting any of those cool effects. Do I need to enable anything?

Better benchmark: I can't watch a movie while amarok is running, because of the framedrops. In xorg, this works fine.

Great how-to and overlay though. XGL seems to be running pretty stable as well.

BTW: anyone know how to make XGL start automaticly when using sdm / gdm / entrance (i.e. what modifications are neccessery to /etc/init.d/xdm?)

I'v build xgl on my amd64 laptop (hp nx9105, GeForce4 440 Go 64M) but when I start xgl it gives following error:

dlopen: /usr/lib64/xorg/modules/xgl/libglcore.so: undefined symbol: _tnl_arb_vertex_shader_stage

Fatal server error:
No GLX modules loaded
dlopen: /usr/lib64/xorg/modules/xgl/libglcore.so: undefined symbol: _tnl_arb_vertex_shader_stage

FatalError re-entered, aborting
No GLX modules loaded
Aborted

OpenGL is working !
Does this mean that the graphics card isn't capable of running xgl?
