Red Hat Bugzilla – Bug 818291
Newer kernels boot to black screen, NVIDIA GeForce 7050
Last modified: 2013-02-13 07:50:34 EST
Description of problem: Kernel image 3.1.0-7.fc16.x86_64 boots fine. Anything newer and the display fails, giving me only a black screen. Trying to switch to a text terminal with ctrl+alt+Fkeys has no apparent effect. So, there's no way to log in locally (thus the "high" severity).
Version-Release number of selected component (if applicable): Kernel image 3.3.2-6.fc16.x86_64 is known to fail. (Other recent updates also fail, but I haven't kept track of exactly the first one to fail. Sorry. When a new images came out in rapid succession, I assumed that one of them was going to fix the problem, and just applied them.)
How reproducible: Try to boot from kernel image newer than 3.1.0-7.fc16.x86_64.
Steps to Reproduce:
1. Start computer
2. Let GRUB default to newest kernel image
Actual results: Black screen. (No "X". No cursor. No TTYs.)
Expected results: Twinkly Fedora logo on calming blue background.
Comparison of messages and Xorg.0.log from a successful and a failed boot show almost no differences. There are no unique errors reported when display fails. (Meaning, there are errors in the logs, but they occur during successful boots, too.)
Oddly, a failing kernel image detects an HDMI connector, but no DVI. A working kernel image detects a DVI connector, but no HDMI. However, while there is an HDMI connector present, there is *not* a DVI connector, and, for added fun, the monitor is actually connected to a D-SUB connector.
Some logs available. Let me know what might be useful.

The attached failing log includes lines about the HDMI port, while the working log doesn't.

I have seen this problem too with F16 (64 bit) and still have the problem with the latest Fedora 17 64-bit, including all updates.
During boot or at least within 5 minutes I get a black screen. There is no way out other than to reboot. Ctrl-Alt-Delete sometimes works. It also happened during install/upgrade with Anaconda.
I have a GeForce GT220. It doesn't matter if I use the HDMI, DVI or both outputs.
My only workaround is to install the driver from nvidia.com. I have to re-install it after every kernel update. When I boot in text mode I have a few minutes more before the system freezes to a black screen. Just enough to install the driver from nvidia.com.
Erwin: you have a card of a completely different generation, and therefore your bug is very unlikely to be the same as Mike's. 'It boots to a black screen' is a very generic symptom and is a very poor indicator that two bugs are the same bug. There have been, over the years, thousands of completely different bugs for which the symptom was 'it boots to a black screen'.
Especially since in your case, apparently, it doesn't really *boot* to a black screen, but somehow winds up at one shortly after boot.
Please file a separate bug, with all information requested at https://fedoraproject.org/wiki/How_to_debug_Xorg_problems . Thanks.
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '16'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 16's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 16 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" and open it against that version of Fedora.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
