Description Richard Schwarting 2008-06-08 15:37:42 EDT
Description of problem:

If I try to switch from X to a console (eg. alt F2), the screen goes black.  If
I do "modprobe vga16fb", then switching back gives me a visible console.  This
is on a "Silicon Motion, Inc. SM720 Lynx3DM" on an Acer TravelMate C100.  

LaundPad has more information in its own bug at

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

How reproducible:


Steps to Reproduce:
1.  Boot up.
2.  Try to start X (which fails for reasons in bug #443544)
3.  Try to return to a console
Actual results:
* the screen is black; you can still login and pass commands to the console, but
you can't see anything on the screen.

Expected results:
* I can see the console and see the characters on the screen, like when vga16fb
is loaded.

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

Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.

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

Thanks in advance.

Sadly, unable to access a web browser from home, I ended up reinstalling Ubuntu.  I intend on trying Fedora 10 on the laptop, and if the issue reoccurs, I'll open the bug.

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  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bug reports from releases that are no longer maintained.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 '9'.

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 9'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 9 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 please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

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: 
Comment 4 Bug Zapper 2009-07-14 13:43:15 EDT
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
