Red Hat Bugzilla – Bug 77695
Init display problems on Toshiba Tecra 8000
Last modified: 2007-04-18 12:48:22 EDT
Description of Problem:
The display isn't initialised properly on startup on a Toshiba Tecra 8000
laptop, when using the default setup as provided by Xconfigurator. In
particular, an external monitor reports "signal out of valid sync range" when
starting the X server on boot or after logout. It is then necessary to cycle
through the different display modes (internal, external or both) via Fn+F-key to
get a display.
To make a long story short, the problem appears to be related to
which are added to XF86Config-4 by Xconfigurator. Everything works a lot better
if these are disabled. (But of course, they will be re-enabled if Xconfigurator
is executed again, which is fairly annoying.)
Version-Release number of selected component (if applicable):
Does the same occur in Red Hat Linux 8.0?
I don't think I'll be able to upgrade to 8.0 on this host anytime soon ;-(
Defering bug report for future review. Please feel free to reopen if the
problem persists in Red Hat Linux 'phoebe' beta release or a later official
