UNFORTUNATELY this laptop shipped with G-SYNC enabled, which means that the Intel GPU is completely disabled and everything goes through/is controlled by the NVIDIA GPU. I would rather have no G-SYNC but having the Intel GPU driving the display output and backlight. I'm sure that it would be a much less painful experience. Well... Enough with ranting! Since you suggested that this may have been fixed by a recent kernel update, I have tested a Fedora 28 Workstation Live Image that comes with the 4.16rc6 kernel. But the problem persists. >From what I could understand, even if the 4.16 corrects the underlying issue, the nouveau driver still needs to be changed and manually recompiled as suggested by the OP because backlight support for Pascal-based cards is not enabled by that switch statement. The "NV_DEVICE_INFO_V0_PASCAL" clause is missing in the "nvidia_backlight.c" file. Is this assessment correct? Also, feel free to ask me for any further information that may help you to fully support backlight control for Pascal GPUs. I may need some instructions on how to gather some lower level information, but I'll gladly do it if you think that it may help.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
