Hello and welcome to the forums.

I have moved your post to its own thread.

Which version of Ubuntu are you using?

Can you open a terminal window, type in (or copy/paste) the following commands, and post back the results:

Code:

---

cat /proc/cmdline

---

Code:

---

for interface in /sys/class/backlight/*; do echo $interface; cat $interface/brightness; cat $interface/actual_brightness; cat $interface/max_brightness; done

---

Code:

---

sudo lspci -vnn | grep -A12 VGA
