[Kernel-packages] [Bug 1775065] Re: No brightness controls and /sys/class/backlight empty after upgrade to Bionic on laptop with GeForce GTX 1060 Mobile (kernel parameter acpi_osi= is a workaround)
I have bought a new laptop and downloaded the latest LTS version of Ubuntu. When I tried to install the dual boot for the first time, it failed, then after adding "nomodeset" to the grub menu I managed to install the same. But after installation there is no gui brightness control as well as the brightness button is not working. I tried a lot of methods to fix this, but none worked.

[Kernel-packages] [Bug 1775065] Re: No brightness controls and /sys/class/backlight empty after upgrade to Bionic on laptop with GeForce GTX 1060 Mobile (kernel parameter acpi_osi= is a workaround)
Got a similar problem on a HP Zbook G5. I have 2 graphics cards: Intel + Nvidia. I use the Nvidia proprietary drivers 415. The difference in my case is that I have an entry in "/sys/class/backlight", namely: "intel_backlight" and that I can control the display brightness using the gnome GUI slider, but also my backlight hotkeys are not working and none of the following kernel parameters solved the issue: "acpi_backlight=vendor" "acpi_backlight=video" "acpi_backlight=video0" "acpi_backlight=none" "acpi_osi=Linux" Since many people are experiencing this annoying bug, it would really be great if it could be solved. Anyhow, thanks for any of your efforts to solve this issue! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1775065 Title: No brightness controls and /sys/class/backlight empty after upgrade to Bionic on laptop with GeForce GTX 1060 Mobile (kernel parameter acpi_osi= is a workaround) Status in linux package in Ubuntu: Confirmed Bug description: This is a case of "Backlight control does not work, and there are no entries in /sys/class/backlight" for what lspci reports as "NVIDIA Corporation GP106M [GeForce GTX 1060 Mobile] (rev a1)" where the kernel parameter acpi_osi= is a workaround.

[Kernel-packages] [Bug 1775065] Re: No brightness controls and /sys/class/backlight empty after upgrade to Bionic on laptop with GeForce GTX 1060 Mobile (kernel parameter acpi_osi= is a workaround)
I can confirm this very same problem in my laptop, which is a Thinkpad P1 with a Xeon E-2176M and hybrid Intel / NVIDIA card working in "Discreet" mode (that is, only the NVIDIA card is enabled) using the proprietary NVIDIA driver installed via the nvidia-driver-390 package (390.87-0ubuntu1). The NVIDIA card is a Quadro P2000 Mobile according to lspci: 01:00.0 VGA compatible controller: NVIDIA Corporation GP107GLM [Quadro P2000 Mobile] (rev a1) I'm currently in Ubuntu 18.10 Cosmic Cuttlefish with kernel 4.18.0-10: $ cat /etc/os-release NAME="Ubuntu" VERSION="18.10 (Cosmic Cuttlefish)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 18.10" VERSION_ID="18.10" HOME_URL="https://www.ubuntu.com/; SUPPORT_URL="https://help.ubuntu.com/; BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/; PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy; VERSION_CODENAME=cosmic UBUNTU_CODENAME=cosmic $ uname -ar Linux rosmon 4.18.0-10-generic #11-Ubuntu SMP Thu Oct 11 15:13:55 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux And just to confirm, what I'm seeing is this: 1. Pressing the media keys for brightness cause not visible effect (no brightness change), with errors showing up in the journal: oct 23 11:37:47 rosmon gsd-media-keys[2532]: Failed to set new screen percentage: GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._gsd_5fpower_5fmanager_5ferror.Code0: Screen backlight not available oct 23 11:37:47 rosmon gsd-media-keys[2532]: Failed to set new screen percentage: GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._gsd_5fpower_5fmanager_5ferror.Code0: Screen backlight not available 2. Installing xbacklight allows me to effectively change the brightness from the command line (e.g. `xbacklight -set 50`, `xbacklight -inc 10`...) 3. The /sys/class/backlight directory is empty, suggesting that the ACPI interface was not initialize, which I believe is why the media keys don't work and throw that error in the journal (media keys -> gsd-media- keys -> gsd-power-manager -> GUDev -> /sys/class/backlight ACPI interface): $ ls -l /sys/class/backlight/ total 0 4. Booting with acpi_osi= or acpi_osi=Linux causes the /sys/class/backlight directory to be populated with a thinkpad_backlight directory, and the media keys to respond showing the OSD for the brightness, but does not change brightness at all when used: a. The brightness bar is always shown at "random" values between 0 and ~20% b. /sys/class/backlight/thinkpad_backlight/actual_brightness is always 0 Also, in this setup where /sys/class/backlight/ is not empty, xbacklight does NOT work. I hope this is helpful, as it's kind of annoying to have to use xbacklight to change brithgness. I was myself looking into a fix for this, but I can't figure out whether this should be fixed in the NVIDIA driver, some kernel module or somewhere else, so I figured I'd comment here and hope for the best. PS: I can do more tests if needed.

[Kernel-packages] [Bug 1775065] Re: No brightness controls and /sys/class/backlight empty after upgrade to Bionic on laptop with GeForce GTX 1060 Mobile (kernel parameter acpi_osi= is a workaround)
Yes, this was after an upgrade to Ubuntu 18.04 LTS (Bionic Beaver) from Ubuntu 17.10.1 (Artful Aardvark). The bug is fixed in the mainline kernel; I have added the appropriate tag and marked the bug as confirmed. ** Tags added: kernel-fixed-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Tags added: apport-collected ** Description changed: This is a case of "Backlight control does not work, and there are no entries in /sys/class/backlight" for what lspci reports as "NVIDIA Corporation GP106M [GeForce GTX 1060 Mobile] (rev a1)" where the kernel parameter acpi_osi= is a workaround. (The workaround is also recorded on Ask Ubuntu at https://askubuntu.com/questions/1030526/brightness-on- laptop-msi-gt72vr-in-ubuntu-18-04-with-nvidia-gtx-1060-mobile- does/1043598#1043598.) The problem is new for me after upgrade to Bionic, although the cause might be the corresponding update to the NVIDIA drivers. I will add attachments following the instructions at https://wiki.ubuntu.com/Kernel/Debugging/Backlight, though most of them seem to be uninteresting. If I can provide further information, please let me know.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.17 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

Although step 3 at https://wiki.ubuntu.com/Kernel/Debugging/Backlight asks for the output of ls /sys/class/backlight, it gives no output, so I do not include an attachment. Steps 9, 10, and 12–16 either cause no changes or do not apply. Step 11, as noted, is a workaround. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed in Ubuntu. https://bugs.launchpad.net/bugs/1775065 Title: No brightness controls and /sys/class/backlight empty after upgrade to Bionic on laptop with GeForce GTX 1060 Mobile (kernel parameter acpi_osi= is a workaround) Status in linux-signed package in Ubuntu: New Bug description: This is a case of "Backlight control does not work, and there are no entries in /sys/class/backlight" for what lspci reports as "NVIDIA Corporation GP106M [GeForce GTX 1060 Mobile] (rev a1)" where the kernel parameter acpi_osi= is a workaround.
