[Bug 1518473] Re: /sys/class/backlight/acpi_video0/brightness is broken
link-dupont really nailed it! I am having the same issue on an HP Elitebook 8770w with ONLY an NVIDIA Quadro K3000M, using the proprietary driver version 387.34 on Fedora 27, Kernel 4.14.3-300 I tried all: acpi_backlight=video acpi_backlight=vendor acpi_backlight=native to no avail, so removed all of that and installed inotify-tools, I do have /sys/class/backlight/acpi_video0 so I ended up with the following script in /home/YOURUSERHERE/Scripts/backlight_inotify.sh #!/bin/sh path=/sys/class/backlight/acpi_video0 luminance() { read -r level < "$path"/actual_brightness factor=$((100 / max)) printf '%d\n' "$((level * factor))" } read -r max < "$path"/max_brightness nvidia-settings -n -a BacklightBrightness="$(luminance)" inotifywait -me modify --format '' "$path"/actual_brightness | while read; do nvidia-settings -n -a BacklightBrightness="$(luminance)" done And then created file brightnessfix.desktop under /home/YOURUSERHERE/.config/autostart [Desktop Entry] Name=Brightness Fix Exec=/home/YOURUSERHERE/Scripts/backlight_inotify.sh Terminal=false Type=Application Name[en_US]=backlightfix.desktop It is a very effective workaround, thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1518473 Title: /sys/class/backlight/acpi_video0/brightness is broken To manage notifications about this bug go to: https://bugs.launchpad.net/system76/+bug/1518473/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I can confirm the problem, I installed kubuntu yesterday and it take about 30 seconds to get a usable desktop. I will try "empty session" solution and report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1509334 Title: [sru] plasma-nm blocks temporarily on startup w/o bluetooth device – KDE/Plasma very slow to launch (Kubuntu 15.10) To manage notifications about this bug go to: https://bugs.launchpad.net/plasma-nm/+bug/1509334/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
