On a ThinkPad X13s with a 6.0.7 Kernel, when attaching an
external screen via a docking station or dongle, I get the
following error in the Kernel log and it doesn't work:
[...] Nov 18 20:14:25 x13sarm kernel: [drm:dp_ctrl_link_train [msm]] *ERROR* max v_level reached Nov 18 20:14:25 x13sarm kernel: [drm:dp_ctrl_link_train [msm]] *ERROR* link training #1 failed. ret=-11 Nov 18 20:14:25 x13sarm kernel: [drm:dp_display_process_hpd_high [msm]] *ERROR* failed to complete DP link training [...] The strange thing is: It worked once. I got the external screen detected and properly working. From the second time on I only got this message and the screen stays black. |
