Hi, I've got said Lifebook, with SXGA+ screen. When I run the 915resolution-program and try to change the Mode "3c" to 1440x1050, it will not complain, but the mode will still be the old one when I list the modes and resolutions again. So Xorg only runs with 1280x1024, which is unusable. Also, when I start X, it complains about missing agpgart-device: (EE) GARTInit: Unable to open /dev/agpgart (No such file or directory) (WW) I810(0): /dev/agpgart is either not available, or no memory is available for allocation. Using pre-allocated memory only. (II) I810(0): Checking Lid status enabled Is there a reason why it will not detect my I855-chipset? What can I do?
