Hello, |
2 |
I've got a new laptop and see a strange behaviour when disconnecting |
3 |
and reconnecting my USB-C screen. |
4 |
Here are the steps that I am doing. I have a dual screen setup with |
5 |
xrandr, with my notebook screen being the primary screen and a second |
6 |
large external screen connected via USB-C to my notebook directly. |
7 |
Now I disconnect the USB-C cable and do not do anything software wise, |
8 |
i.e. my X-Server is still pretending to run on two screens, I can move |
9 |
the screen outside of my notebook screen (into the area where the |
10 |
external screen). |
11 |
Now I reconnect the USB-C cable but the screens stays blank (the the |
12 |
screen it says "No USB Type-C connection from your computer"). The only |
13 |
way to get a signal again is to first use xrandr to only use my |
14 |
notebook screen, and at the exact time udev gets a DRM event, and |
15 |
suddently my external monitor appears within xrandr as connected (I did |
16 |
not touch the cable, I only ran an xrandr command to use only the |
17 |
notebook screen). Right after the DRM event I can run the xrandr |
18 |
command to use both screens, but it is annoying to degrade first to one |
19 |
screen, because all windows are moved around and I do not end up with |
20 |
the same window setup as before. |
21 |
|
22 |
Using the same screen with the same experiment as described above but |
23 |
with a different notebook the screen is able to pick up the signal |
24 |
again, so it's not purely a problem with the external screen. |
25 |
Any idea what is going on and how I can workaround it? I just want to |
26 |
disconnect the cable and reconnect it without the need to switch any |
27 |
xrandr setup. |

Thanks for your ideas and help |
