Hi to everyone, I've got an Asus 1215N. I use Mandriva 2010.2 x86_64. Recently I've compiled kernel 2.6.38 from kernel.org.
In my linux distribution i915 and nouveau kernel module are blacklisted, and I've uncomment this 2 line in /etc/modprobe.d/blacklist-mdv. So I can load both this 2 modules: # lsmod | grep i915 i915 487045 2 drm_kms_helper 34769 2 nouveau,i915 drm 215732 5 nouveau,ttm,i915,drm_kms_helper i2c_algo_bit 5705 2 nouveau,i915 button 6065 2 nouveau,i915 i2c_core 30375 7 nouveau,videodev,i2c_i801,i915,drm_kms_helper,drm,i2c_algo_bit video 12802 2 nouveau,i915 # lsmod | grep nouveau nouveau 675181 0 ttm 66834 1 nouveau drm_kms_helper 34769 2 nouveau,i915 drm 215732 5 nouveau,ttm,i915,drm_kms_helper i2c_algo_bit 5705 2 nouveau,i915 button 6065 2 nouveau,i915 i2c_core 30375 7 nouveau,videodev,i2c_i801,i915,drm_kms_helper,drm,i2c_algo_bit video 12802 2 nouveau,i915 I've this in /etc/fstab: # cat /etc/fstab | grep debugfs none /sys/kernel/debug debugfs defaults 0 0 When both i915 and nouveau are loaded in the kernel I can see this in /var/log/messages : kernel: VGA switcheroo: detected DSM switching method \_SB_.PCI0.P0P4.GFX0 handle kernel: nouveau 0000:04:00.0: power state changed by ACPI to D0 kernel: nouveau 0000:04:00.0: power state changed by ACPI to D0 kernel: nouveau 0000:04:00.0: enabling device (0000 -> 0003) kernel: nouveau 0000:04:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 kernel: [drm] nouveau 0000:04:00.0: Detected an NV50 generation card (0x0a8b00b1) kernel: vga_switcheroo: enabled kernel: [drm] nouveau 0000:04:00.0: Attempting to load BIOS image from PRAMIN kernel: [drm] nouveau 0000:04:00.0: ...

I've see this in messages: kernel: fbcon: Remapping primary device, fb1, to tty 1-63 kernel: i915: switched off Any suggestions to make other steps to enable the nvidia card? What I can do now? Thanks
