My guess is that the HDMI connector is wired to the Nvidia card, while the panel to the IGD. You could confirm what is the actual wiring either asking from DELL, or if possible in Windows by disabling the Intel driver, leaving only the Nvidia driver enabled. You could also check if there is a BIOS setup option to change the output, although it could be hard-wired without muxing capability. If the output is connected to the Nvidia card, you wouldn't need reverse PRIME to enable it. Depending on the connection (native HDMI or via an LSPCON DP->HDMI converter) you may also need LSPCON support in the Nouveau driver, not sure if it exists.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
