I have a notebook with NVidia GT520M (which uses Optimus technology) and after a long and bloody fight I finally put it to work through Ironhide.
Last night I let my notebook be out of battery by accident. After reboot and login, the default screen changed from 1366x768 to 1024x768 and the screen brightness init with 0 (screen totally black, brightness adjusted by the keyboard controls). Note that the login screen is Ok, perfect resolution and brightness...
How can I change back this values? And what happened :-T ?
Thank you all!!
I can't access NVidia settings, always crash Ironhide.
When I change the resolution by xrandr or "Screen" interface it'll ok, but I always lost the configuration after reboot.
After I install Ironhide for the first time, I reboot the system several times, and it was ok.
