Recently I moved to Windows 10, willing to play some games. I had to turn on some options in BIOS of my Dell Precision 7520, to redirect all video through Nvidia Quadro M2200, and to HDMI. Now I am back to Ubuntu, turned on switchable graphics in my BIOS, switched to Intel using prime-select intel, but can't enable my desk monitor through HDMI.

Unfortunatelly, I also used a command prime-switch intel not knowing exactly its purpose.

Ubuntu 23.10

My current BIOS settings are:

Enable Switchable Graphics checked

Discrete Graphics Controller Direct Output Mode checked

prime-select intel prime-switch intel

How to properly configure the system to use Intel VGA (low-power consumption) and multi display?

You mention Ubuntu, but give no details as to what Ubuntu product, and what release of that unstated product. Why not tell us. – guiverc Feb 13 '24 at 08:04

Does this answer your question? How can I switch back to Nvidia card from Intel with Nvidia-prime – Daniel T Feb 13 '24 at 08:19
@DanielT no, as I wrote, I run this command, with no success, except that system switched to Intel, but no output to HDMI – qba-dev Feb 13 '24 at 10:09
In your question you ran the command prime-select intel; prime-switch intel. Clearly you only ran it because you wanted that the "system switched to Intel". If you want to switch back, you could have tried prime-select nvidia ; prime-switch nvidia – Daniel T Feb 13 '24 at 10:14
I don't want to switch to Nvidia. My system must run Intel, not Nvidia. – qba-dev Feb 13 '24 at 10:18
That won't work unless your laptop has a MUX switch: https://wiki.archlinux.org/title/hybrid_graphics – Daniel T Feb 13 '24 at 10:43
But it worked fine until yesterday. – qba-dev Feb 13 '24 at 18:20
