xen-3.2.1 kernel-2.6.18 dom0 x64 (Dual-Core AMD Opteron(tm) Processor 8220) domU 32bit: 2.6.18 kernel debian 5.0 (lenny) on lvm partitions The domU was created by xen-create-image from xen-tools. Inside the domU I have installed the X related packages (xfce4, gdm, etc.) with aptitude. Now, when I login via "ssh -X", I can start xclock and other X applications, but when trying to start glxgears or glxinfo I get: $ glxgears libGL: XF86DRIGetClientDriverName: 4.0.1 r200 (screen 0) libGL: OpenDriver: trying /usr/lib/dri/r200_dri.so glxgears: ../../src/xcb_io.c:461: _XRead: Assertion `dpy->xcb->reply_data != 0'' failed. Aborted What is missing? Or is it possible to use OpenGL applications (remotely) inside a domU at all? Btw. has anybody here experience with *remote* (not xen related) OpenGL apps? I usually face two kinds of message: libGL error: open DRM failed (Operation not permitted) libGL error: reverting to (slow) indirect rendering or libGL error: open XF86DRIAuthConnection failed (Operation not permitted) libGL error: reverting to (slow) indirect rendering (but in this case the application seems to run...) -- Zsolt _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
