Bug 150333 – screen size reported incorrectly to wm in xinerama mode

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Carl Michal 2006-10-06 16:56:15 UTC]

If I login in text mode, and then start up a dual-head xinerama session
with startx (with XSESSION=Gnome in rc.conf), the window manager seems to be terribly confused about the size of the composite screen.  I can move the mouse everywhere, but I can't move windows into places.  I've tried this with both twm and metacity and they both show the same problem (started up metacity, then killed it to try twm).

If I just start the X server with: X at the console, either window manager behaves properly.

Having tried a couple more things:  if the session is started from gdm, there is no problem.  

If XSESSION is set to Xsession, and started from startx there is no problem.

I only see this if XSESSION=Gnome, and it is started with startx.

looks like this is a intel driver bug, which version is it ? (adding x11 herd, maybe they know something about this)

[Comment 3 Rémi Cardona (RETIRED) 2007-12-22 14:01:44 UTC]

Carl,

Do you still see that bug? If so, don't hesitate to reopen this bug with an up to date emerge --info and the version numbers for gdm, xorg-server and whatever video drivers you are using.

Thanks
