I've make a fresh install with Ubuntu 12.04. Unfortunatly i've a problem with colors and brightness settings. Before reinstall of Ubuntu, i used Ubuntu 10.10 with same graphic card, and same nvidia drivers. Note: Only nvidia proprietary drivers works for my GeForce 8600 GTS.
- With nvidia-settings: adjust colors, brightness: no effects
- With xgamma -gamma 0.5 : no effects
- Try to use f.lux or redshift: no effects
I try solutions found on internet like here but no working to.
Any idea ?
