Dell Precision M6700 laptop running Debian 12 (bookworm) with default desktop
External monitor connected to HDMI port shows blank white screen except for very top edge. I can see the mouse cursor when it is moved to the very top. Settings->Display detects the second monitor, and I can select from a list of resolutions, but nothing changes the symptoms.
If I connect the external monitor to the laptop VGA output, it works correctly (but only at 1024x768).
output of lspci:Output of xrandr with second monitor connected to HDMIoutput of nvidia-detect:Using Debian package manager Synaptic I found a large number of packages dealing with the tesla-470 driver. Do I need all of these, or just the 'nvidia-tesla-470-driver'?
TIA,
Frank
