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 Option "externDisp" Option "internDisp" 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): 4.2.0-8 (+ Xconfigurator-4.10.7-1)
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 ;-(
