Hi, folks. Time for some crowdsourcing!
So I'm trying to poke this rather infamous F16 / F17 bug:
https://bugzilla.redhat.com/show_bug.cgi?id=745202
What I'd like to get more info on is exactly what cards are affected by it.
The bug causes corrupted rendering of GNOME Shell elements on older NVIDIA GeForce cards, when using the nouveau driver. So far there seem to be two similar but slightly different forms of corruption discussed in the bug. The one that seems to be associated with NV30 cards looks like this:
And the one that seems to be associated with NV40 cards looks like this:
In both cases, there's clearly incorrect rendering of text in GNOME Shell elements like the top panel, the overview, and the User menu - but *not* in regular applications. In the NV30 case at least, the top panel is often an incorrect color (not black).
The cards under 'suspicion' are all those listed in the 'NV30 family' and 'NV40 family' here. Broadly, that's GeForce FX 5xxx, GeForce 6xxx cards and GeForce 7xxx cards, but it's a bit more complex than that - there's some Quadro (workstation cards) included. You can verify your exact card and compare it to the 'NVxx' model number given in that chart by looking either for a line "NOUVEAU(0): Chipset: "(foobar}" in /var/log/Xorg.0.log, or doing 'glxinfo | grep renderer' and looking at the result.
If you have any of the chips listed as being in the NV30 or NV40 families, can you please test an up-to-date F16 or F17 with gnome-shell - a live image of F17 is fine, the Alpha should be okay for testing this. PLEASE USE NOUVEAU. The bug is relevant to nouveau only. It does not happen with the proprietary driver, we know that, and we don't need reports from the proprietary driver. Also, the bug only affects Shell, so you have to test Shell - it doesn't happen in fallback mode, or KDE, or Xfce, or LXDE. Please post the following info:
* Your exact code name, as given in the Xorg.0.log or glxinfo | grep renderer output
* Whether you tried F16 or F17
* Whether you saw the corruption
If you see some other bug or some other form of corruption, that's interesting too, but please state that: it's important to know whether you actually hit the precise corruption discussed in 745202 (so, whether your screen looks like one of the two screenshots). If you're not sure, post a screenshot.
I'm particularly interested in reports of cards in the above two families which do *not* show corruption in Shell (but remember, USE NOUVEAU!), and reports from NV30, NV31, NV35 and NV36 cards, if anyone still has any of those.
Thanks a lot, everyone!

I think the fan is dead on that one, though. But I have a spare fan sitting here ready...
