I am using Gnome, if that's what you mean by 'which desktop'. The monitor is BENQ 2400 Eco (FullHD).
Ok. GNOME should definitely have a tool for the display/screen setup. Question is still open, whether "xrandr --auto" did help to enable the external monitor. (In reply to Simon Herrmann from comment #14)
Apart from this it's an Intel/NVIDIA combo. Always kind of problematic. Things get easier when disabling one of the devices in BIOS/Firmware - if possible.
I don't see an option in the BIOS for choosing or disabling a graphics adapter.
Ok. Meanwhile I believe I can rule out an issue with the Intel/NVIDIA combo. Seems Intel is enabled and connected to the external outputs. NVIDIA probably is only used for better rendering performance (optional). (In reply to Simon Herrmann from comment #15)
BTW, most likely the desktop was confused by the strange monitor layout (internal display having a different and even bigger resolution than the external one), made some unlucky/wrong assumptions and failed completely in the end.
Actually I chose this monitor layout, because the one before was incorrect. Could that really prevent the monitor from showing something? I hope not... (as it works on Ubuntu just fine)
Can't say. Please try 'xrandr --auto' as outlined before and above.(In reply to Simon Herrmann from comment #12)
Picture of the setup
Thank you for the drawing, that is actually my setup, because my external monitor is left of my Laptop screen. But the external monitor is much bigger than the internal display. Gnome does not seem to know about differently dense panel resolution ;-)
Oh. You did this by intention. Wow! -- You are receiving this mail because: You are on the CC list for the bug.
