![]() ![]() I think this could be done through the NVidia profiles option provided from nvidia-settings. Some people have tried to set the performance level manually, but report it's unsafe and may kill the GPU. If someone knows what to do in this situation, please share!ĮDIT : I did some further digging and it seems there is no obvious or safe solution. TL DR: NVidia settings are reset after reboot and tried everything I could find on the Internet to no good. I read all the related articles, but mainly people complain about brightness being reset or dual-monitor configs, which solutions involve some specific app that doesn't help me in any way. I tried to edit the etc/X11/nf, but it's empty - there are zero lines in that file. I tried gksu-ing and setting it, but it didn't work. After the reboot the setting is cleared and the problems still persist, so I have to manually set it again for the current session. The problem is this only works until I reboot. The fix is to go to nvidia-settings and change the power-mode from 'Auto' to 'Prefer Maximum Performance'. It has to do with the NVidia card going into low-power mode and then videos and 3D effects suffer from tearing and stuttering. I had the infamous flickering issue at one point and found a way to fix it. The setup runs smoothly overall except for when it comes to video and 3D performance in Ubuntu. I am running a GeForce GTX 770 on a Z87 Gigabyte mobo and dual-boot Windows 8.1 Pro and Ubuntu 12.04.3 LTS. ![]()
