I found this from Kraptor in another thread (164589) dealing with flicker: 1) The file nvidia-kernel-nck: - You use the 169.12 driver, so it os the nvidia-new driver, it must be specified correctly. - You must tell the driver it is a mobile card, if not the PerfLevelSrc may not work. - So you must have these lines (and I only have these two, not three like you): alias char-major-195* nvidia options nvidia_new NVreg_Mobile=1 NVreg_RegistryDwords="PerfLevelSrc=0x2222"
2) The location of nvidia-kernel-nck: - You may have (like me) two versions of this file. One in /etc/modprobe.d/ and another in /etc/modutils/ - The file in /etc/modprobe.d must be the one that applies when the driver is loaded and is the file we talk about. - The file in /etc/modutils/ must contain only next line: alias char-major-195 nvidia I don't have this second file, and in fact don't have the directory called /etc/modutils. Is it necessary, and should the settings be the same as mentioned in 2) if my driver is different from the one he is talking about ? -- laptop video output garbage https://bugs.launchpad.net/bugs/234292 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
