hp pavilion dv7 hdmi not working

i have a hp pavilion dv7 i can not get the hdmi to work. 13.1 it works with windows.

That doesn’t tell us much at all. Which graphics chipset do you have? If ATI/AMD or Nvidia, are you using proprietary drivers, or the default open source drivers?

/sbin/lspci -nnk |grep VGA -A3

Another thought: Does your laptop have hybrid graphics?
The requested ‘lspci’ output and the following will help us confirm

xrandr --listproviders

Additional steps may then be needed to get the hybrid graphics working as expected, (including the HDMI output which is normally-connected to the discrete graphics device).

/sbin/lspci -nnk |grep VGA -a3

Your output shows that you are indeed using hybrid graphics. Since you are using the open source radeon driver, I believe you can use vgaswitcheroo to switch between the Intel and AMD card.


I’m not aware of any good openSUSE documentation on the subject, but here’s are Linux Mint and Ubuntu guides that may be useful to you

I know little about hybrid graphics (and would actively avoid it if purchasing a new laptop), but I believe that if the proprietary driver is installed, it now supports switching via its own ‘control centre’ utility. However, this may depend on the particular hardware involved.

Hopefully, others more familiar with your hardware can advise further from here.
