Bug Description

Binary package hint: xserver-xorg-video-nv

My display is Grainy / Blurrred / Distorted with nv driver on hardy RC at 1024x768. I will upload an image

The display looks like it has been 'greyed out' in a windows 95 style (except the cursor looks fine).... What I mean by this: the text looks a bit like it has had a layer of dots placed over it and so it is hard to read - it gives a blurred and grainy appearance.

Some things I noted:
1. See the attached screenshot from when using the driver and compare it with the photo of the screen
2. The cursor renders fine
3. 800x600 resolution looks fine

This is on a Samsung X10 with an nvidia GeForce FX Go 5200 64mb. Other people seem to have had this working on other distros in the past. I am using 8.04 daily build from 20th April

The vesa and nvidia drivers can do this fine at all resolutions. The nv driver looks fine at 800x600 but terrible at 1024x768.

I have tried turning off the composite extension, and not loading the glx module

I am reluctant to use the nvidia one because it breaks suspend for me...

Reducing color depth to 16bpp works around this issue. The problem is not new: I saw it already a year ago on Fedora 7 live CD.

I can confirm this problem;
the 16bpp workaround works but that's not a solution (at least for me) because seems to be slower than 24/32bpp.
(nvidia break suspend also on my amd64 system).

(Some have reported that changing to a 16bpp color depth works around the issue.)

Thank you for reporting this issue about xserver-xorg-video-nv. Starting
with Lucid, Ubuntu is transitioning to using the -nouveau video driver
by default instead of -nv. The reason for this change is because
upstream development for the -nv driver has been quite slow. We are
quite pleased with the upstream development speed for -nouveau, and hope
this will translate into swifter bug fixes as well.

Because of this, I'm closing this bug report at this time. I'm marking
it wontfix because what you describe is probably a valid issue, but we
do not have further plans to work on it in Ubuntu. If you would still like
to see this issue investigated, I would encourage you to file it
upstream at http://bugs.freedesktop.org/.

Nobody is supporting xf86-video-nv and it will be going away at some point in the future. If your problem persists with nouveau or the proprietary driver provided by nVidia, please re-file accordingly. We apologize for the inconvenience.

This is part of an automated bulk action; if you believe that this bug was closed in error, then change the targeted component and reopen it.
