I am unable to change graphics card on Kali Linux 4.6.0, Debian 4.6.4-1kali1 (2016-07-21) x86_64 GNU/Linux with Gnome. Machine running is a HP Pavillion DV6.
I have tried:
Reinstalling AMD drivers: does nothing even after multiple reboots
Uncommenting grub config files: does nothing even after multiple reboots
Using vgaswitcheroo: executes commands yet commands does absolutely nothing, integrated graphics remain + and Pwr while discreet is dynoff (see output 1 at bottom of page)
Using DRI_PRIME: errors (see output 2)
and many many more...
I am really running out of ideas and have gone through every post I could find on SE and other forums...
# sudo cat /sys/kernel/debug/vgaswitcheroo/switch 0:DIS: :DynOff:0000:01:00.0 1:IGD:+:Pwr:0000:00:02.0
2. editting conf
# DRI_PRIME=1 glxinfo |grep renderer Error: unable to open display
