--- Comment #15 from Tommaso Fonda <[email protected]> --- I have news. Today I booted my affected laptop and brightness control is working fine. I had not installed any system updates since opening this bug... So I am unsure whether the issue is still present and comes e.g. from some kind of race condition and thus may not always appear, or if it got fixed for good somehow. I'll reboot the machine a few times today and in the next few days to see what happens. -- You are receiving this mail because: You are watching all bug changes.
