Hi James, Ward, Adam! Thanks for your help! To James: Yes, I've an intel card. I followed many guides. My card is : Identifier "Card0" Driver "intel" VendorName "Intel Corporation" BoardName "Mobile 4 Series Chipset Integrated Graphics Controller" BusID "PCI:0:2:0" To Ward : attached you'll find Xorg.0.log, xorg.conf and lspci.out To Adam: I tried 'eselect opengl list', but the only answer has been [1] xorg-x11 * I'm going to try exa. Thanks a lot, Massimiliano >
