Using docking staion, second external screen stuck with two resolutions.
Hi,
I'm running Ubuntu 18.04 on a Dell Lattitude 5480 with i-tec USB-C Dual docking station and two Iiyama ProLite XB2481HS screens. My second screen hooked up with DP <-> HDMI cable is stuck with two resolutions (800x600 and 1024x768) and is not being recognized by Ubuntu. This is what I'm seeing in dmesg Code:
[ 895.973941] i915 0000:00:02.0: DP-4: EDID is invalid: [ 895.973946] [00] ZERO 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 895.973948] [00] ZERO 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 895.973950] [00] ZERO 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 895.973952] [00] ZERO 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 895.973953] [00] ZERO 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 895.973955] [00] ZERO 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 895.973956] [00] ZERO 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 895.973958] [00] ZERO 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |
