Upgrading my Alienware 17 R4 laptop to the 465.24.02 driver breaks the backlight control. The backlight is very bright (probably 100%) with the 465.24.02 driver and cannot be changed. Reverting back to the 460.67 driver restores the backlight control.

This regression is still present in 465.27.

Still present in 465.31. Downgrading to 460.67 still fixes the issue. Is this regression confirmed/being looked into? For the record: Backlight doesn't work at all / Laptop Issues / Arch Linux Forums

This regression is still present in 470.42.01. The last working driver I’ve found is 460.73.01. @amrits - @aplattner - Can you please acknowledge that you’ve seen this bug and are going to look into it?

regression still present in 470.57.02

nvidia-dkms 460.67-1 was working fine with 5.12.15, but then I upgraded to linux-5.13.4 and it breaks, I’m getting this error when upgrading: ==> dkms install --no-depmod -m nvidia -v 460.67 -k 5.13.4-arch1-1 Error! Bad return status for module build on kernel: 5.13.4-arch1-1 (x86_64) Consult /var/…

[image] 460.67 Incompatible with Kernel 5.13 at the moment Linux I know this isn’t entirely uncommon, but I figured I’d let everyone know that at the moment, the Nvidia proprietary driver isn’t compatible with kernel 5.13. DKMS fails with: CC [M] /var/lib/…

Same issue here: everything works with 460.67 and breaks from 465 on. OS: Arch Linux GPU: GeForce TX 1060

Linux 5.13.4 - Nvidia driver 470x, brightness issue present Downgraded to Linux 5.12.9 and nVidia driver 460x. Brightness control now works again. Kernel parameter (acpi_osi=) (pcie_aspm=force) works for me. There isn’t a lot of documentation on this regression. OS:Arch Linux 5.13.4 (Downgraded:…

I’m also experiencing this issue on a Dell G15 5515 with a NVIDIA GA106M (RTX 3060 Mobile). I haven’t been able to get the backlight to work with either linux 5.10.54 or 5.13.4 with the nvidia 470.57.02 driver. I am now compiling the Linux 5.12.9 kernel now to try to use with the nvidia 460x drive…
