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?

it is normal until now, watch this thread for an solution

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.

Code: Select all

~> Xgl :1 -ac -accel glx:pbuffer -accel xv

Exact same problem here, compiled everything just now ....

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.

any nvidia user getting same results???

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

steve_d555 · Post by **steve_d555** » Mon Feb 13, 2006 11:25 pm

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.

Ok, here you go.
Any effect, including wobbly runs great in both kde and gnome - no stuttering at all. Glxgears went form 4600 to 7900. Only one problem: compiz managed windows don't appear in kicker which makes using kde a bit difficult, but gnome runs fine. (too bad I don't like gnome)
I don't have doom3 installed anymore, so can't test that.

The specs:
- full ~x86 system
- GCC 3.4.5
- CFLAGS="-O2 -march=pentium-m -fomit-frame-pointer -pipe"
- nvidia-glx-1.0.8178
- nvidia-kernel-1.0.8178-r3
- my card: Geforce Go 6600
- used the hanno overlay that was available at the time of compiling, which is xgl-overlay-200602130.tar.bz2

For extra fun, play with the friction and spring_k settings (use gconf-editor for that) for some really wacky wobble effects.

ok cool I've got xgl up and running, compiz starts just fine and turns my xgl server background blue... but when i run gnome-window-decorator nothing happens, so i cant move apps about ???

Exact same problem here too. It's probably a new issue from using code off of CVS.

have a look on page 7 of the thread "XGL part 2" there is a fix for that issue, it just involves tweaking a few files and recompiling xgl

Works perfectly with

That happened to me too. I tried a lot of different things and eventually it stopped doing that, but I don't know what fixed it. I stopped putting "gconf" in the command line for compiz, put a "sleep 1" in between each statement in the script I use to start Xgl, and I added "decoration" after "gconf" to active_plugins in gconf-editor. I also start gnome-window-decorator before any apps.

See if one of these scripts works for you.

To start Xgl in a window (change "gnome-terminal" to whatever app you want to start inside it):

Code: Select all

Xgl :1 -ac -accel glx:pbuffer -accel xv:fbo &
sleep 1
LD_LIBRARY_PATH=/usr/lib/opengl/xorg-x11/lib/ DISPLAY=:1 compiz --replace decoration move resize place menu fade switcher cube rotate zoom scale &
sleep 1
DISPLAY=:1 gnome-window-decorator &
sleep 1
DISPLAY=:1 gnome-terminal &

Or, emerge gnome-light, and then kill your xorg. Some of you may need to run "/etc/init.d/xdm stop" to cleanly shut down regular Xorg so that you can start fullscreen Xgl with this script. Trying to run this while KDE is already running results in gnome-session complaining that there's already an active session manager. Once you're down to the textmode/framebuffer linux console, run this script:

Code: Select all

Xgl :1 -ac -accel glx:pbuffer -accel xv:fbo &
sleep 1
DISPLAY=:1 gnome-session &
#DISPLAY=:1 startkde &
sleep 4
LD_LIBRARY_PATH=/usr/lib/opengl/xorg-x11/lib/ DISPLAY=:1 compiz --replace decoration fade move resize place menu switcher minimize cube rotate zoom scale &
sleep 1
DISPLAY=:1 gnome-window-decorator &

all works... but no wobbly and no Italian keyboard layout...

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?)

Hmm. That is odd. I get a glxgears increase and I am able to run 2 movies and quake3 at the same time without slowdown. However, when compiling everything slows to a crawl and nothing is possible in XGL.

I get this aswell

. My 6600GT goes from 11kfps to 6kfps from xorg 7 to xgl. And i get unusable graphic dostorsions

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

Does this mean that the graphics card isn't capable of running xgl?

I have the same card, so it shouldn't be that. I can't help you with the error, though, as I've never seen it. Maybe something to do with 64-bit mode?

For me, xgl itself works, but I get the black windows with glxcompmgr and compiz.

has anyone got it working on an MX card?

any geforce MX users got around the black window bug?

ive got a geforce 4 mx400 and from all the threads ive read no one with a geforce MX card can get compbiz to work
