Description yybvsursmq 2011-02-02 03:16:46 UTC

Description of problem:
Trying to upgrade or install Fedora 13 or Fedora 14 on my Thinkpad T20 gives me a black screen when using graphical install. If I use text mode it installs but then running it gives a black screen.  Fedora 12 installs and runs just fine.

This makes my T20 unusable for Fedora.

Version-Release number of selected component (if applicable):
Fedora 13, Fedora 14

How reproducible:
Always.

Steps to Reproduce:
1. Attempt upgrade or install of Fedora 13 or 14 in graphics mode.
2. Upgrade or install in text mode and then boot into new O/S
3.
  
Actual results:
Black screen either on install in graphics mode or running installed by text mode.

Expected results:
Proper upgrade or install with working system.

Additional info:
Possibly some sort of X or video driver support for T20 video got zapped in the transition from Fedora 12 to 13 which wasn't fixed in 14?

Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information especially concerning your hardware we require that will be helpful in our diagnosis of this issue.

When you install Fedora in a text mode, start X after from the text mode (run startx as a normal user). If it fails, still /var/log/Xorg.0.log, /etc/X11/xorg.conf (if there is any), and the output of dmesg program from the failed attempt to start X would be useful.

We will review this issue again once you've had a chance to attach this information.

Thank you very much in advance.

Sorry for taking so long to get back to this bug.

I freshly installed Fedora 14 off of the full DVD using the basic VESA driver and that went OK.

Rebooting and starting X from the text mode still showed a black screen.

I rebooted again by hitting the power switch and all of a sudden it all worked.

Really really strange, and this still doesn't mean that this worked.

Xorg.0.log from the boot time where there was a black screen was at 0 length; nothing got written.  Also, the gdm log was 0 length.  dmesg didn't show anything useful; it found the Intel drivers with no errors.

I don't know what else to say about this; I seem now to have a working system, but this should not have happened.

I guess this bug can be closed since I can't provide any more info.

Then it must be something else than Xorg issue ... even in the most disasterous situations we go to great lengths to provide plenty of logs.

Closing, but feel free to reopen if you will find out something new.
