Brightness keys3/11/2023 ![]() Please try that driver and then let us know if the problem persists, however, as mentioned, the FN key is added by the OEM so in this case I would also recommend to get in contact with Asus*. This information is offered for your convenience and should not be viewed as an endorsement by Intel* for the merchants or services offered there. * Please be aware that the content on that site is not controlled by Intel*. I found the following support site with drivers: To avoid potential installation incompatibilities, we recommend that you first check with your computer manufacturer and use the driver software provided. Computer manufacturers can change the features, incorporate customization, or make other changes to the graphics driver software or software packaging. Now, I say to use their driver because we supply generic versions of graphics drivers for general purposes. If this was a graphics problem then the solution would be to use the latest graphics driver from the system manufacturer. Having the grub menu working is also a minimal safety net when tempering with boot settings, so it makes sense to address this first if you see this too.Thank you for your response and I understand that you are currently experiencing issues with the "FN" brightness of your system.įirst, I would like to start by letting you know that the FN or function key is added by the different system manufacturers and not by Intel ®. After this, update-grub needs to be run (which the above dpkg-reconfigure will do as well). I recovered it by editing /etc/default/grub to contain GRUB_TERMINAL=console, GRUB_TIMEOUT_STYLE=menu, and GRUB_TIMEOUT=10. I fixed Failed to Set MokListRT: Invalid Parameter by following (a KDE Neon adapted version of) Shibiwan's answer on Ubuntu 20.04 Failed to Set MokListRT: Invallid Parameter.Doing this might have interacted with the effectiveness of my fix: To adjust the screen brightness, look for an icon that corresponds to brightnessoften a sun logo or something similarand press the keys. I saw two more boot-level issues after the upgrade and I fixed them too. Often, these keys are part of the row of F-keysthat’s F1 through F12that appear above the number row on your keyboard. What else I did (may have interacted with the above fix) I was using older driver (390), because it was the only one that allowed me to play sound over HDMI. I think this is a common problem, but one to which I have not yet managed to find a solution After replacing the LCD screen of my Dell Inspiron 6000, the brightness controls (ie the FN + up/down cursor keys) have been reversed - for example, pressing the increase brightness key makes the screen dimmer, even though the on-screen control thinks it is getting brighter. Both were applied before on my machine and remained active after the upgrade, so not related. ![]() Also, MacBook Air 3,2 by default may fail to boot usable graphics altogether in Nvidia drivers, which is fixed by setting certain PCI-E registers in grub as per Proprietary NVidia drivers with EFI on Mac, to prevent overheating. In particular, you need to add X-related device option settings EnableBrightnessControl=1 as per Brightness not working after installing NVIDIA driver. Note that Nvidia drivers on MacBook Air 3,2 have a whole set of other, unrelated issues, some specifically related to brightness control. ![]() KDE Neon, Nvidia video drivers, kernel 5.4.0-54-generic.Macbook Air 3,2 (very old, tends to have EFI boot issues related to graphics).brightness 0.8) allowed me to change brightness, but system keys still do not work and using xrandr resets screen colour (night colour mode) Renato Miotto's solution (via xrandr -output.Problem was as described above, first found after upgrade to Ubuntu 20.04 (brightness worked before).However, I add more details on my setup and what else I did below. Moreover, package names after dpkg-reconfigure auto-complete in my bash, but your settings may vary.ĭoing this should always be safe and quick, so it would not hurt to try this before you do anything else. If you are unsure, run uname -r to get the kernel name. Brightness Keys: adjust brightness for all displays at once Volume Keys: adjust the volume of the active monitor Input Hotkeys: set hotkeys to switch to other HDMI, DisplayPort or USB-C ports The brightness keys can also adjust only the monitor with the cursor on it. Obviously, you should run this with the package of your current boot kernel. The same familiar keys can now control your external monitors. For me, the problem was solved by simply rebuilding the initrd another time after booting into the new kernel: sudo dpkg-reconfigure linux-image-5.4.0-54-generic ![]()
