Hi all, seems like i have a strange problem. I'm using gentoo for amd64 with a nvidia quadro fx500, i've installed nvidia drivers. Kernel modules and nvidia drivers and extension work correctly ( as detailed in xorg log files). If i login in fluxbox or blackbox opengl works correctly (glxgears at 4000 fps), but if i try the same test after login in kde-3.3, glxgears runs at 20 fps ! even kde GL screensaver run very very slowly. I was thinkingit could be a qt problem (ie: qt compiled without opengl support), but i verified that opengl flag has been used during qt compilation. Any suggestion? (about kde configuration) Thank ___________________________________________________ . Account management: https://mail.kde.org/mailman/listinfo/kde. Archives: http://lists.kde.org/.
