No, it's compiled into the kernel. It is a 16MB card according to the startup messages in kern.log though. My other machine has 32MB according to kern.log and that has similar symptoms, but I haven't investigated that one so thoroughly. I've tried adding mem:16M to the kernel's video options, and then mem:8M but neither made any difference. The FB bits of my kernel config are below. Have I got something wrong there? I think CONFIG_FB_MATROX_I2C is superfluous and that isn't enabled on the second PC. Maybe the problem is due to having VESA enabled too? Or because I use fb consoles? # # Graphics support # CONFIG_FB=y CONFIG_FB_CFB_FILLRECT=y CONFIG_FB_CFB_COPYAREA=y CONFIG_FB_CFB_IMAGEBLIT=y CONFIG_FB_SOFT_CURSOR=y # CONFIG_FB_MACMODES is not set CONFIG_FB_MODE_HELPERS=y CONFIG_FB_TILEBLITTING=y # CONFIG_FB_CIRRUS is not set # CONFIG_FB_PM2 is not set # CONFIG_FB_CYBER2000 is not set # CONFIG_FB_ARC is not set # CONFIG_FB_ASILIANT is not set # CONFIG_FB_IMSTT is not set # CONFIG_FB_VGA16 is not set CONFIG_FB_VESA=y CONFIG_VIDEO_SELECT=y # CONFIG_FB_HGA is not set # CONFIG_FB_NVIDIA is not set # CONFIG_FB_RIVA is not set # CONFIG_FB_I810 is not set # CONFIG_FB_INTEL is not set CONFIG_FB_MATROX=y # CONFIG_FB_MATROX_MILLENIUM is not set # CONFIG_FB_MATROX_MYSTIQUE is not set CONFIG_FB_MATROX_G=y CONFIG_FB_MATROX_I2C=y # CONFIG_FB_MATROX_MAVEN is not set # CONFIG_FB_MATROX_MULTIHEAD is not set # CONFIG_FB_RADEON_OLD is not set # CONFIG_FB_RADEON is not set # CONFIG_FB_ATY128 is not set # CONFIG_FB_ATY is not set # CONFIG_FB_SAVAGE is not set # CONFIG_FB_SIS is not set # CONFIG_FB_NEOMAGIC is not set # CONFIG_FB_KYRO is not set # CONFIG_FB_3DFX is not set # CONFIG_FB_VOODOO1 is not set # CONFIG_FB_CYBLA is not set # CONFIG_FB_TRIDENT is not set # CONFIG_FB_GEODE is not set # CONFIG_FB_S1D13XXX is not set # CONFIG_FB_VIRTUAL is not set -- TH * http://www.realh.co.uk _______________________________________________ directfb-users mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
