Xenialpup64 7.5
Frugal with save folder.

Cpu-frequency scaling tool
set to use the intel_pstate scaling driver.

This driver only has powersave or performance governors.
That is by design, so normal.

It defaults to performance.
If changed to powersave.
The change is shown as being made.
However it does not actually change.

The change is suppose to be recorded in /etc/init.d/wcpufreq

wcpufreq file has only this in it
Code:
#!/bin/busybox ash

Subject description: xenialpup64 7.5 screen too dim
 

HP 15bs162sa laptop, Intel i5-8250U quad core with Intel UHD graphics 620 chip built in, 4 Gb ddr4 memory, 1Tb hard disk, UEFI, Intel radio chip 3168NGW (AC3168).

Still sorting out my new laptop (running xenialpup64 7.5, frugal with save folder, usbstick).
Wireless and printing sorted, now it's the graphics turn.
The screen is rather dim and the keyboard keys for controlling brightness do not work. Windows 10 has complete control using the "Intel UHD Graphics Control Panel". Intel say the chip is supported on linux but they do not themselves supply a driver and I lost my way trying to follow there links for someone that does.
I did find files called "brightness" , "max_brightness" and "actual_brightness" in /sys/class/backlight/intel_backlight/. The brightness" file has the number 300 in it (and nothing else) and the file called "max_brightness" has 1500 in it. So tried changing the 300 to 500. Instant success! BUT it is not persistent and reverts to 300 on next restart.
So now I know it's possible to change the brightness, can anyone tell me how I should be doing it. I'm guessing there must be a program somewhere that can, but where?

Another minor problem I have is that the cpu temperature icon always says 27 degrees and only shows cpu frequencies when clicked. Haven't got anywhere with that yet.

All help/advice gratefully received!

If you try the following syntax does it brighten the screen?

echo 500 > /sys/class/backlight/intel_backlight/brightness

If so, you could put that command into a /root/Startup script and it should set the brightness each time you boot or restart the X server.

Go to menu->setup->Screen/Graphics wizard->monitor gamma calibration
In each color entry adjust equally
Negative number - to lower brightness
Positive number - to increase brightness.
Apply
exit
After closing program:
Select Yes to save current configuration.

@Greengeek: It works.
I have made several files that write different numbers to "brightness" (300,500, 600, 700, 800). Just click on the files to vary the brightness - and putting the best one in startup works. Many thanks!

@bigpup: Also works - but colours look a little washed out. Sticking to Greengeek's idea.

Thanks for the help folks - best forum I've come across.

it took me a lot of trawling to resolve the brightness control on my lenovo x230, I also found how to get cpu frequency control

see the last 2 arguments on the end of my grub

Code:
  kernel /xenial64_7.5/vmlinuz   psubdir=xenial64_7.5 pmedia=atahd pfix=fsck intel_pstate=disable acpi_osi="!Windows 2012"

Greengeek and Ledster
I had the same problem with adjusting the brightness on my laptop and using your advice I now have three files to adjust my brightness at a click. Thanks!

Great, glad to hear that worked.

Some other users will find that their machines do not use "intel" backlight and will need a different script - the following one might work for some users:
Code:
echo 5 > /sys/class/backlight/acpi_video0/brightness


However - the actual number which represents max brightness will be different for different hardware. On many machines it is possible to discover what value your machine sees as the max brightness level by running the following code:
Code:
 cat /sys/class/backlight/acpi_video0/max_brightness


On my machine I also used a different method - I used "xbacklight" and put a couple of icons in the system tray to increase or decrease backlight intensity as required (see pic below). The good thing about xbacklight is that it allows you to increment and decrement the brightness rather than setting an absolute value. This means you can bind an "increment" script and a "decrement" script to the keyboard keys that should normally have these functions.

Hopefully xbacklight will be available in the xenial repos.
