Ubuntu Dapper + 7800 GT > OpenGL doesn't work

The most common cause for an X segfault when loading the glx module on a Debian based system is /etc/init.d/nvidia-glx.

You could try reinstalling the driver with the --force-tls option, first set to new, and if that doesn't help, 'classic'.

The only thing that I see in your bug report is that you specified a kernel source path of /usr/src/linux-headers-2.6.15-26-386, which shouldn't be neccesary at all. However, that is unlikely to cause the X segfault you're experiencing.

You also have some ACPI errors in your bug report, which may or maynot lead to instability, but they would be unlikely to cause the X segfault:
[17179590.444000] ACPI-0158: *** Error: Method execution failed
[\_SB_.PCI0.SBRG.TPM_._HID] (Node dffe4f40), AE_AML_NO_OPERAND
[17179590.444000] ACPI-0158: *** Error: Method execution failed
[\_SB_.PCI0.SBRG.TPM_._UID] (Node dffe4f20), AE_AML_NO_OPERAND

GLX still crashes but there is a change : GLX was commented (#) in the "xorg.conf", so the installer wrote a new GLX line in last place :

Section "Module"
Load "i2c"
Load "bitmap"
Load "ddc"
Load "extmod"
Load "freetype"
Load "int10"
Load "type1"
Load "vbe"
Load "glx"
EndSection

This way, I can boot Ubuntu but craches each time GLX is requested.

I post the last report (zipped)...

netllama, I have to say you're a really great guy!

Problem solved! It was the ACPI, I have just truned the ACPI Services out and now GLX works. I didn't think about that before.

Thank you, thank you

If disabling acpi fixes the problems, then you're hitting either a kernel or BIOS bug.

Thanks,

I've just one more question for you : is it possible to use XGL/Compiz with the official 8762 driver? Because all info I found about XGL/Compiz and Ubuntu tell to install nvidia-glx...

Thank's, xelios.

nvidia-glx is the official driver. It just has some packaging, pre & post installation script changes, but the core driver is the same.
