Hello How should i enable Nouveau driver in a custom kernel. Here is how i compiled my kernel: 1_make localmodconfig 2_make menuconfig and then went to: device drivers --> Graphics support --> Nouveau Support 3_make 4_make modules_install 5_make install and after booting the kernel i tried loading Nouveau by following commands: 1_insmod drm.ko 2_insmod drm_kms_helper.ko 3_insmod ttm.ko 4_insmod nouveau.ko but in the last step it gives me Unknown symbol in module here is the result of "dmesg | tail" after i tried insmod nouvea.ko: drm: module verification failed: signature and/or required key missing - tainting kernel [ 212.330197] [drm] Initialized drm 1.1.0 20060810 [ 255.336591] nouveau: Unknown symbol i2c_bit_add_bus (err 0) [ 255.336610] nouveau: Unknown symbol mxm_wmi_call_mxds (err 0) [ 255.336625] nouveau: Unknown symbol mxm_wmi_supported (err 0) [ 255.336644] nouveau: Unknown symbol i2c_bit_algo (err 0) [ 255.336719] nouveau: Unknown symbol wmi_evaluate_method (err 0) [ 255.336777] nouveau: Unknown symbol wmi_has_guid (err 0) [ 255.336904] nouveau: Unknown symbol mxm_wmi_call_mxmx (err 0) I don't know in what step i did wrong. thank you.
