Description Benjamin S. Scarlet 2004-07-14 07:58:56 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510

Description of problem:
When using the nv driver to drive an MSI card with a GeForce FX 5200
connected via DVI to an LCD screen, starting the X-server produces
only a solid color or garbage, depending on options and extensions used.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Configure X server for "nv" driver and DVI out (some combination of
Option "CrtcNumber" "1"
Option "FlatPanel"
2. Start X-server

Actual Results:  Screen garbage. Usually a solid blue screen, but
depending on whether I try disabling fancy extensions, sometimes
vertial cyan stripes or such. No cursor, no apps. "ps" shows the gdm
greeter happily up and running and this is a fresh install so I don't
think it's an app problem. Switching to the vesa driver makes it work,
but not at acceptable resolution.

Expected Results:  Should have gotten a gdm greeter, or at least a
cursor. No screen garbage.

Additional info:

I realize that since this is the "nv" driver, I'll probably just get
directed to go to the "nv" driver maintainer (who, last I knew, worked
for nvidia). However, with the whole XFree86 -> X.org thing, I'm not
clear on where I should file this bug to get it to the right person.

Hi Benjamin,

The canonical bug tracker for X.Org X11 is the "xorg" component
in freedesktop.org bugzilla, located at http://bugs.freedesktop.org

It isn't yet clear who is the official "nv" driver maintainer anymore
upstream, but the best place to file bug reports related to the "nv"
driver is in a central location, which the official X.Org bugzilla
is probably the best currently.

While it is true this is an open source driver in a sense, in
practice, it really isn't very open source, because the driver
source is heavily obfuscated.  It uses hexadecimal I/O addresses
and values rather than symbolic register names and values, thus
making it next to impossible for anyone outside of Nvidia to make
meaningful modifications to the driver.  ;o(

Hopefully Nvidia is still planning on maintaining and updating
the "nv" driver for the future, and will track bugs in the X.Org

Please paste the URL here if you file a report in freedesktop
bugzilla, and I'll track the issue there also.

Thanks for the report.

Status update:  Doing an upstream bug scan/update, and this bug report
does not have an associated upstream bug report to track.

Our Fedora development contains a new release of xorg-x11 which may
resolve this issue, but requires testing by the original reporter.
If the problem still exists in rawhide xorg-x11, whoever is still
experiencing this issue can file a bug report in X.Org bugzilla
as mentioned in comment #1 above, and we will track the issue in
the upstream bugzilla.

Setting status of bug to "MODIFIED" pending testing of rawhide
xorg-x11 by reporter.

Note to QA: Please change bug status to "RAWHIDE" when Fedora Core 3
ships, unless there are additional comments present indicating the
problem still exists.
