Hi Everyone :) I just beginning new post in new year with Xubuntu fresh installed on X260. A bit of problems around. This post will relate to one problem I found recently. Problem:   I cannot bring bring `brightness` back after return from suspend. Summarize solutions:   1.1. Create this file by command `sudo touch /usr/share/X11/xorg.conf.d/20-intel.conf`   1.2. Add this to file Section "Device"         Identifier  "card0"         Driver      "intel"         Option      "Backlight"  "intel_backlight"         BusID       "PCI:0:2:0" EndSection   1.3. Restart or may be logout and login   2.1. Edit this file by command `sudo vi /etc/default/grub`   2.2. Modify previous to with this GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux apci_backlight=vendor"   2.3. We should restart, i guess Fi...

I'm got new machine from new workplace, It's HP Probook. It's look quite good but I have got a problem about changing screen brightness doesn't work. So I google and found this https://askubuntu.com/questions/332657/cannot-change-brightness-setting-using-function-buttons-or-using-the-brightness, This blog put me through that problem. So this is my note sudo vi /etc/default/grub for this var GRUB_CMDLINE_LINUX="", set value "acpi_backlight=vendor" sudo update-grub restart then , yeh, many thanks for https://askubuntu.com/users/183206/aaditya-bagga
