Now brightness settings are correctly saved, but I have a new problem: changing brightness level doesn't produce any effect (both with or without Nvidia driver installed) Today I received many Ubuntu updates (kernel included), and I also installed freshly released Nvidia 381.09 driver (via “Graphics Drivers” team - Proprietary GPU Drivers PPA).
I can adjust the screen brightness, but after restarting the screen brightness of my laptop resets to maximum. Ubuntu 17.04 doesn't save my brightness settings. Firmware attacks are much more dangerous than OS-based attacks because firmware is invisible to OS-based security solutions.ĪMI’s Zero Trust firmware security solutions can help maintain firmware integrity and strengthen organizations’ Zero trust strategy.Non-Optimus laptop ASUS G752VS (Nvidia GTX1070)
But without secure firmware running on the infrastructure, Zero Trust strategy weakens significantly.įrom your car to airport kiosks and power grids, nearly all technology is powered by firmware and for that reason, firmware attacks are on the rise. Zero Trust security is essential for protecting an organization’s infrastructure and business critical data in today’s digital transformation.
