Public bug reported: I have Lenovo ThinkPad e590, which connected via USB Type-C to Lenovo Dock station. To doc station connected network cable, USB mouse, keyboard, power, and two monitors.
On previous kernel versions (include 5.0.0-37) it works ok. But after update to any version on 5.3.0 I can't use it with doc station: 1) If I boot with connected Dock station then 2 external monitors are black and laptop monitor the same black 2) If I boot without connected Dock station then Laptop works ok. At the moment when I connect USB Type-C cable to laptop screen become black, and 2 external monitors show the image, but it hangs: I can move the mouse cursor but all other UI hangs, even the clock does not work, only REISUB helps. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Description changed: I have Lenovo ThinkPad e590, which connected via USB Type-C to Lenovo Dock station. - To doc station connected network cable, USB mouse, keyboard power and two monitors. + To doc station connected network cable, USB mouse, keyboard, power, and two monitors. - On previous kernel versions (include 5.0.0-37) it works ok. - But after update to any version on 5.3.0 I can't use it with doc station: - 1) If I boot with connected Dock station then 2 external monitors are black and laptop monitor the same black + On previous kernel versions (include 5.0.0-37) it works ok. + But after update to any version on 5.3.0 I can't use it with doc station: + 1) If I boot with connected Dock station then 2 external monitors are black and laptop monitor the same black 2) If I boot without connected Dock station then Laptop works ok.
