- I am having some serious issues with the Switchable graphics setup on my HP Envy 1103-tx Laptop.
This laptop comes with:
Intel HD Graphics 4000
AMD Radeon HD 7670M
The ATI card is getting really hot making the laptop uncomfortable for use.
To fix the issues I have tried a few things but they didn't really complete:
Setting Power Profiles using echo "low" > /sys/class/drm/card1/device/power_method which failed with an Invalid argument error. No additional kernel parameter set.
Turning Off the card using echo OFF > /sys/kernel/debug/vgaswitcheroo/switch which did nothing at first and after adding radeon.dpm=0 to the kernel parameters the command lead to a crash with black screen and error log which got fixed after a hardware reboot.
