Ctrl+Key shortcuts not working (Linux)

[beelze]

Just built from scrcpy-9999.ebuild. Ctrl+Key shortcuts not working, instead it acting like plain key is pressed (i.e. Ctrl+V entering v letter in input field).

Related to #300?

It works for me on Debian 😕

[beelze]

No, it's a PC box. Is there any way to debug keypresses to help resolve an issue?

[rom1v]

If you can compile from sources, finding the guilty commit would help (since I cannot reproduce).

If v1.4 works, there are very few commits to test. Anyway you can git bisect.

[beelze]

Just prepared to bisecting or whatever, but decided to rebuild before and check again.

Well, there are some news: in fact, LCtrl-key generally working fine, but RCtrl+key – not. (Perhaps last time I've used only RCtrl). For instance, RCtrl+v produces v in input field; RCtrl+s produces s in input field and then opens recents.

Another problem: I've found that pasting stops on first non-latin[?] character. I.e. trying to paste abcЭЮЯ123 produces only abc

Funny problem: Almost all non-modifier keypresses are «doubled». I've tried to press aABbCC and got aaaABbbBcCCC in input field. Backspace and right/left arrow keys are «doubled» too.

BTW, is there any way to get device clipboard to computer?

That's not expected. RCtrl works for me.

Are you sure your RCtrl key works?

Yes, that's "expected" (only ASCII chars are supported).

Funny problem: Almost all non-modifier keypresses are «doubled». I've tried to press aABbCC and got aaaABbbBcCCC in input field. Backspace and right/left arrow keys are «doubled» too.

Maybe you can help on this issue: #109 (comment). I'm not able to reproduce.

See #145.

Are you sure your RCtrl key works?

Absolutely. Everyday I'm using LCtrl+C but RCtrl+Ins, in particular. Here's xev output for pressing LCtrl+c and, immediately after, RCtrl+c, maybe it would be helpful:

Thorougly checked, I've found that only alpha chars, arrows, Backspace, Del and Enter are «doubled». Digits and punctuation chars are not. Maybe it will help. Looks like a different problem.

[beelze]

That's not expected. RCtrl works for me.

As I mentioned previously, it isn't «not working at all».

RCtrl+s produces s in input field and then opens recents.

You may find this interesting and relevant.

I've checked Ctrl+key in openboardview and mpv (both libsdl2 dependent too), both L/RCtrl works fine. (Though I almost not looking into code)

[spvkgn]

Same here in Ubuntu 18.04 (MATE Desktop) with v1.10 and prebuilt server. Can't paste clipboard - both LCtrl-v and RCtrl-v just produces v letter. And all other Ctrl-key not works as well.

[rom1v]

Does it still happen?
