[nvidia-glx-new] only stripes with NVS140M

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please attach your X server configuration file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.0.log) to the bug report as individual uncompressed file attachments using the "Attachment:" box below. Could you please also try to run without any /etc/X11/xorg.conf and let Xorg autodetect your display and video card? Please also attach the /var/log/Xorg.0.log from this attempt. Thanks in advance.

Could it be the EDID of the display? That's at least what I guess to be the cause at the moment. The attached part of my Xorg.0.log suggest that (to me). (Gutsy with nvidia did not have this problem on the same machine.)

Hm, our displays have the same EDID.

That would be an explanation why another person with nearly the same notebook and the graphical card does not have this problem.

The nvidia driver has an option that makes it ignore the EDID (see: http://us.download.nvidia.com/XFree86/Linux-x86/171.06.01/README/appendix-b.html for the option Option "UseEDID" "boolean").

I am not a xorg.conf expert (far from it) but there should be a way to teach / tell the nvidia driver to ignore the display edid (nv knows how to use it and the gutsy nvidia driver did so, too) without (!) losing the edid for external displays like beamers.

Can somebody help?

This option did not solve the problem.

X starts only in low resolution mode.

The nvidia beta driver (see http://www.nvidia.com/object/linux_display_ia32_173.08.html) works - more or less. Solutions, links and descriptions can be found here: http://ubuntuforums.org/showthread.php?p=4842513#post4842513

There seem to be some problems with this driver: a) after I attach the beamer my computer "slows down" b) the use of desktop effects and an external beamer crash Hardy. I will now test this beta driver without the beamer. Let's see what happens ...

Indeed the beta driver work.

So I hope they will be published in the repositories as they become final.

To prevent the drivers from repositories to be loaded at startup I had to add the following into /etc/default/linux-restricted-modules-common

DISABLED_MODULES="nv"

Here, nvidia loads without these settings as the default driver. Because of the kernel-update yesterday I switched back to nv.

What kernel-update?

Do you use Hardy?
Don't you simply have to rebuild the kernel module after a kernel update?

ad1) Kernel now is 2.6.24-17-rt
ad2) Yes - 8.04 LTS - Ubuntu Studio Version
ad3) I would have had to reinstall it or build a new kernel module - but because of beamer-troubles (see above) I threw nvidia out completely. I'll wait for the next release and try again then ...

Thanks for updating the bug report. Since this has enough information for a developer to begin work I am going to set it as confirmed and let them help you from there.

since it requires a new driver version, setting the priority as low.

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.

Everything has been working fine since I upgraded from Hardy to Gutsy ... and Natty doesn't trouble me with this bug either. There could (!) be a problem with the nv drivers in Natty, too, regarding compiz - but that's a different story I'd say.

I would close this bug or mark it "obsolete for all versions of Ubuntu before and after 8.04" - if I knew how to do this. The simple solution, after all, is: dist-upgrade!

Darn: An "edit-button" would be nice to have here. One cannot upgrade from Hardy to Gutsy - I meant upgrade from Hardy to Intrepid. Sorry.
