![]() ![]() Save the file and then type this command in the Terminal: sudo update-grub In the Terminal run this command: gksudo gedit /etc/default/grubĬhange the line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"īy adding a space after the word “splash” and then add the parameter that worked. To work, then make the change persistent. If one of the parameters allows xbacklight Repeat the steps with all the parameters if necessary. The arrow keys, go down to the line that starts with: linux /boot/vmlinuz.ro quiet splash $vt_handoffĪdd a space to the end of the line and then add the first parameter below: If no menu shows then hold down the shift key while starting. The effect will only last for one session. You can try testing the kernel parameters in the GRUB file. If it doesn't work, then try each kernel parameter again and see if xbacklight now works. Where X is the value you got from testing. In the "Command" window put: xbacklight -set X In the new window, under "Name" you can putĪnything you want. Go to Menu → Preferences → Startup Applications. If the setting is not right then decrease the value by 5 or 10 at a time. Then open the Terminal and type: xbacklight -set 100 I would suggest installing xbacklight from the synaptic package manager. ![]() Maximum brightness: echo 648 | sudo tee /sys/class/backlight/intel_backlight/brightness (PS: need to turn on notifications, I think - didn't get this for a few days!)ĭid you try using this command without removing the sudo? You don't need to type "sudo su" first. I will now try the code in terminal you've suggested and report back with my results. just before it reaches max setting, the screen flashes bright for a split second, then dims again to its default level pressing repeatedly now shows the "thermometer bar" returning to max setting. ![]() pressing about 5 or 6 times shows that "thermometer bar" setting decreasing and the screen brightness diminishing up to a point, then although the "thermometer bar" continues to decrease, the screen does not dim any further pressing once shows the "thermometer bar" at max setting an onscreen display appears with either keystroke combination Just a note on the default behaviour of the and key combinations in Petra - this is before I do anything to the settings: I've just re-installed Petra on this system (too much experimentation with different settings and I have no idea where I am now, so starting fresh) and will try your suggestion before I do anything else. I had googled before and found that page (sorry I failed to mention that). You will find a Standard VGA Adapter listed there, where there is supposed to be an Intel HD graphics adapter listed.Thank you for your reply, Roblm. Your issue lies in the device manager under the display adapters device manager category. ![]() You may as well try the driver on the discussion below first, and if it doesn't work, then substitute the hardware ID's for the Intel graphics adapter your model has.Īny notebook I have ever owned lists the monitor as a Generic PnP monitor. The only suggestion I can offer would be to try this workaround which is to modify a W10 driver to work on W7. The problem is that Intel only developed W10 graphics drivers for platforms with the 7th gen core processors and Kaby Lake chipsets.
