EVGA 01G-P3-N959-TR Nvidia GeForce 9500 GT 1GB 128-Bit DDR2 PCI Express 2.0 x16 video card to replace the integrated Intel i5-660 graphics has resolved the problem. Possibly relevant, glxgears FPS increased to a range between 500- 1400 FPS with the add-in video card. Currently using the Nouveau driver with this card, not the Nvidia proprietary driver. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxx http://lists.xen.org/xen-users
