Late reply, hope the people here have already solved the initial issues. Side note: I still don't know how to fix the brightness issue for non X11 users. I have been using the discrete graphics mode preset inside the BIOS, and I am able to plug in a second monitor in my HDMI port with no issues. I changed my session into X11 and added the Option "RegistryDwords" "EnableBrightnessControl=1" line into the "Device" section of this file: /etc/X11/nf, which can be created by using the Nvidia X Server settings program. Of course using Wayland will not work with a X11 config file. This one drove me really crazy, but it turned out that I did not pay attention which Display Manager my Ubuntu session was using. It seems that this is somehow already integrated in my Ubuntu version (21.10). I could hear some fan noises when I changed into the red mode (power mode), but the fan noise disappeared when I changed into white (automatic mode) or blue (silent mode). I am not quite sure if this one works per default. Just change the value inside /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode to 0 or 1. Oftentimes you can change the values inside of them from 0 to 1 or vice versa. You can find the configuration files under /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00. Have a look here for the GitHub source code. This module seems to support a wide variety of Lenovo devices. The kernel developers added an ideapad kernel module, which contains some files that you can configure to your beliking. How would I solve the brightness and external monitor issue in both modes?Īfter some time I am now back with updated infos, which I hope will help future owners of the Legion 5 (whatever exact model it might be):Īs it seems, there is no need for Lenovo Vantage in GNU/Linux in general. Furthermore, plugging in an external monitor via HDMI works with discrete mode, but not with hybrid mode. In hybrid mode however, I could change the screen brightness. One big issue I had with the graphics drivers was that I could not change the screen brightness in discrete graphics mode. When analyzing the wattage/power consumption of my hardware, nothing changes. The 3 power modes (red > white > blue) switched by clicking FN+Q don't actually do anything in Linux but only change the LED on the power button. Once I turned on battery conservation mode in Windows (to charge the battery only to 55-60%), I can't find any way to disable or re-enable it in Linux. the feature to turn on/off the camera (instead of your face, a grey camera is visible in a live video chat to others) is not working. You might say it is a bad product, but I actually use it quite a lot. I can't find any alternative to Lenovo Vantage. I tried to install Ubuntu on my Legion 5 17" with a 1660ti and a Ryzen 7 4800H. This feature is only available on 20 models.I know that parts of this question were asked before, however, none of the questions featured all problems that I have encountered and the answers were rather unhelpful in my case. Accepted values are 2-7, where 2 is the fastest and 7 is the slowest. Values represent a few seconds each, where 0 is the fastest and 9 is the slowest.ĭetermines how quickly the fans accelerate or decelerate when it is time to change fan speeds. Only available in Discrete Graphics Mode (Hybrid Off).ĭetermines how often LegionFanControl should check the current temperature before deciding to change fan speed or not. Removes laptop control of the fans so they run at their factory maximum speeds. Some users may want to disable this behaviour if they use other tools to manage their Windows Power Plan switching events Will also switch corresponding Windows Power Plans if they existĬhoose whether switching the Legion Power Mode will also switch the corresponding Windows Power Plans if it exists.
