The system: OS: Linux Mint 15, Graphics card: Nvidia GeForce 9500 GT, Drivers: nvidia-310 proprietary drivers.
The problem: My monitor has a recommended refresh rate of 60hz, and I want to have it set at that. As stated I'm using Nvidia proprietary drivers and I can set the refresh rate to 60hz either from there or with
xrandr, but everything resets after boot or login.
At the moment I have automatic login in my account. I put a line in
xrandr sets my refresh rate back at 60hz. At boot the system sets the refresh rate correctly, i.e. the login screen has the correct refresh rate set, then, during login, it sets it to 75hz, and, once again, xrandr sets it back to 60hz. This simply prolongs the boot time with 1-2 minutes, which is really not pleasant.
The culprit: The thing that caused all this was the installation and starting of Tux Racer, after which the system started setting the refresh rate at 75hz. I've had the same problem on Ubuntu 13.04 where this started after playing TeeWorlds, but the result was the same.
To note is that this happens only on an account where the game was played, all other accounts do not exhibit such problems. Creating a new account would solve this problem, but I'm not really keen of porting my home folder, having used the system for a while.
Any help would be highly appreciated.
If possible, I would also like an explanation why this happens.
