Version: (using KDE KDE 3.4.2) Installed from: Gentoo Packages Compiler: gcc-3.3.5 I'm not sure whether this is a kde or an xorg/x11 bug, the gentoo people say it's KDE. Ok, here we are ... Summary: Xinerama setup, two screens, KDE-3.4.2: I found that any opengl widget (glxgears [xorg], qt opengl examples [qt], opengl screen savers [kde]) is displayed on primary screen (left) only. If moved to the secondary screen (right), any opengl-widget "vanishes" and reappears only if moved back to the right screen. Note on opengl screen savers: they seem to take the second screen into account (e.g. fireworks), but it's just black, no display at all ... A detailed description can be found here: http://forums.gentoo.org/viewtopic-p-2688188.html#2688188 Another report to bugs.gentoo.org is here: http://bugs.gentoo.org/show_bug.cgi?id=104304 Any hints what's wrong?
Different setup: SuSE 8.x, KDE-3.4.0 (compiled from sources), Qt-3.3.4, XFree-4.3.0 xinerama enabled, Matrox G550 -> glxgears works fine on both screens
Reassigning to kwin. Maybe Luboš has an idea.
Unless you can prove it works outside of KDE, which I doubt, this is either opengl or X problem, so please first test without KDE and then either reopen or report to them.
You're right, doesn't work under plain X either. Should have checked before reporting anything -- sorry. Daniel
