https://bbs.archlinux.org – I have Samsung NP300V5A laptop, with GeForce GT520MX installed. After nouveau installation I saw some errors I've never seen before, and I didn't find anything useful on the web on that matter. Any suggestions appreciated.dmesg|grep nouveau:[   11.002437] nouveau  [  DEVICE][0000:01:00.0] BOOT0  : 0x0d9110a1[   11.002439] nouveau  [  DEVICE][0000:01:00.0] Chipset: GF119 (NVD9)[   11.002440] nouveau  [  DEVICE][0000:01:00.0] Family : NVD0[   11.003658] nouveau  [   VBIOS][0000:01:00.0] checking P (HowTos)
