This behaviour is also present on at least the previous generation mechanical docks, as I regularly disconnect and connect my ThinkPad W550s (2015) to mine. Always have to zap X before suspending the machine prior to disconnecting from the dock, or else open the lid to a black screen where the only way out is to zap X. Reconnecting to the dock is similar; have to zap X before the console shows on all monitors. Back when this machine ran Linux prior to August 2017, monitor detection in this way only worked to a certain extent. It was highly kernel driver-dependent from what I can remember, though the desktop environment or window manager probably played a role here too. This is all with i915kms (doesn't matter which Linux kernel version of drm-kmod), by the way. --=20 Charlie Li Can't think of a witty .sigline today=E2=80=A6 (This email address is for mailing list use only; replace local-part with vishwin for off-list communication) --o73Acp8El6q9qQ54W7cagnrtMzvuq1u2h-- --oHF2Ffe1aEKSQUDP1Vb1klyCXY5L1STDl Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEE/3/Cqr5a+41PbEb+jnB43vIDq2wFAlwknTEACgkQjnB43vID q2y2MQ/7BRVRVxJO5gQt6lBz3ovJXWiKXicLNpVQTtq9JITTa7r19wUu2fOxdCTa tZ4rrUXGGerN7PHu1m6k+n4Tf26ra03hGJUNJ2Fw9NMashYlTjz+4mFEyIOTZ2P3 Fp2kI+H/6Ix2FXYClkmES1RsIayYPE4SJecik1DxiILwdHGOgnVFn16wg+d+P8sA ItEgnIDPLugL8DLpYN/n35YQKu/d/+EO6LNHWhlk0i6mH7Iu/RsNmvHCi0CuMaBp XoUy9pFqGLJVqkwAyxQj4mLgVeld1K3LXmzUT0jXHo/4RphqsU1UFJSOjLc/T7zO bcpFHTXAUcXqv95RwoOVaqAe34wRhJF90yjLKXS/ojH9xnmpZbW0I04pYZiUrw9B ylYH7hHX1c5zpV5s0LY30YmvXDCaCmXxe7A/oludGp893Fm12YAGVOAcUx/1e7lR BXrgwvEC216VZcgeQEsvbK8WITEpV7V0zsuT0R48HwAGT/lcSuEv3C8v2waUdAQX TBaCwzYULBjhiCHAt1Bd/1O9y5VFRGGIng4fEMfAfvvySQ2UEBlBmGoKpmzANAY4 EtYrZ+wKhjmcveyR3VSOkk255rs1O2domyi51SXCQmc63ROK7l04rZJyoUyzkftk b59PEY/pvrIGzsup2WOgtfbn5VDdCe0Bs+HKmLuIKPhrz23UX3k= =uBf8 -----END PGP SIGNATURE----- --oHF2Ffe1aEKSQUDP1Vb1klyCXY5L1STDl--
