some open gl apps freak out.

I'm still researching, but I think this problem has to do with SDL.

here's part of a post that I believe applies to me...

Frozen bubble outputs:
[SDL Init] [Graphics...] [Levels] Fatal signal: Segmentation Fault
(SDL Parachute Deployed)
Segmentation fault

Tuxracer:
Fatal signal: Segmentation Fault (SDL Parachute Deployed)
Segmentation fault

Foobillard:
Fatal signal: Segmentation Fault (SDL Parachute Deployed)

GLTron and Chromium work fine, so it appears to be just SDL and not
OpenGL.

Anyway,  Im using the nvidia driver with dual screens. A gforce3 as
primary agp card and gforce4 as secondary pci card. I suspect that
there is a conflict going on somewhere between using the nvidia
driver, openGL and SDL. and it might have something to do with
the upgraded xfree86.  I'm using xfree86 verssion 4.4.0

I do see a few errors in my log file...
(EE) NVIDIA(1): Cannot read V_BIOS
(EE) NVIDIA(1): Unable to initialize the X Int10 module; the console may not
(EE) NVIDIA(1):      be restored correctly on your TV.

I'm not sure if these are serious errors or not, or if they have
anything to do with some open gl apps either freaking out with
the parachute thingy or just running totally choppy and freezing up.

Can anyone give me some inpute on how to go about solving this?

Re: some open gl apps freak out.

yes glxgears work on both monitors. Something weird though is,
my secondary, using gforce4, use to be like lightening with glx gears.
now it's like it's barely turning.
315 frames in 5.0 seconds = 63.000 FPS
Broken pipe

On my primary with geforce3 glx gears kicks butt.

Everything was working great yesterday and all I did was install
a few file managers to try them out. Worker, Rox and emelfm. I
didn't do anything with them other than with Rox I set a few run
actions to open jpeg files with kwickshow and text files
with kwrite. I tried removing all three file managers thinking maybe
they had something to do with it. I rebooted a few times.
I guess that's what I get for logging in as root to fiddle with stuff.

I did do a pacman -Syu before noticing the open gl problem. I remember
it upgraded Bash. Could that have changed something to do
with gl or sdl?

Re: some open gl apps freak out.

Try also reinstalling nvidia drivers. If you are using nvidia-installer do it with nvidia-installer -f (from cli not gui of course).

Re: some open gl apps freak out.

Thanks tons! reinstalling the nvidia driver fixed the problem. smile Well
I should say mostly fixed the problem. glxgears isback to kicking butt
on both monitors/cards. open gl works great on the secondary
gforce4 pci device. on my primary geforce3 agp device I still
get the sdl parchute thing with foobillard but that doesen't really
bother me. I'm alittle concerned about this message from the
installer.

WARNING: Your driver installation has been altered since it was initially
         installed; this may happen, for example, if you have since installed
         the NVIDIA driver through a mechanism other than the nvidia-installer
         (such as rpm or with the NVIDIA tarballs).  The nvidia-installer will
         attempt to uninstall as best it can.  Please see the file
         '/var/log/nvidia-installer.log' for details.
-> Uninstalling NVIDIA Accelerated Graphics Driver for Linux-x86 (1.0-6106):
-> done.
-> Uninstallation of existing driver: NVIDIA Accelerated Graphics Driver for
   Linux-x86 (1.0-6106) is complete.

Originally, after installing arch,  I downloaded the tarball and
installed the driver with the sh Nvidia_______.run command. Since
then the driver has been updated and I used the nvidia-installer
--update to update it.

Did I mess up by originally installing the driver without using the installer?

Re: some open gl apps freak out.

I get that message every time I install nvidia drivers. It doesn't bother me. I don't know what causes it though.

Even if I run nvidia-installer --uninstall it gives me that error.

Re: some open gl apps freak out.

Actually when I think about it, I never even installed the installer as
being seperate from the driver. It was just part of the install of
the driver. I guess I could interpet that warning as meaning, like
hey! i might not be able to uninstall the stuff I installed the first time, but i'll try smile

Re: some open gl apps freak out.

This message can usually be ignored. It's because you upgraded/reinstalled your x package (somehow) after nvidia installation. Every time you upgrade kernel and x you should also reinstall nvidia. It places its own opengl libs in x subdirectories (and replaces x libs) and reinstalling/upgrading x removes them again (that's probably the reason for low fps in glxgears - it was using native x opengl libs instead of nvidia's). If you have to force nvidia installation use -f option instead of --upgrade for nvidia-installer. The rest depends on your x configuration.

Re: some open gl apps freak out.

That makes sense because I did upgrade xfree86, but afterwards
i reinstalled the nvidia driver. This problem occured after that.
Somehow the driver must have got curupted or something happened to it, or i did somthing it didn't like.

Anyway If i see this problem again I'll know to reinstall the nvidia
driver as being the first thing to do. Thanks guys
