Cannot change linux ttys

[oblivikun]

when pressing ctrl+alt+f1-f6 i cannot switch to a diffirent tty like in other wayland compositors such as sway. i have tried manually adding the bindings in the cagebreak config but it does nothing

[sodface]

It works for me on Alpine with Cagebreak version 2.3.1. What distro are you running?

[oblivikun]

gentoo linux musl, wlroots compiled with vulkan,libinput,drm and x11 backend support

[oblivikun]

im running cagebreak 2.2.3

[oblivikun]

i should probably update cagebreak then check

[oblivikun]

still occurs on cagebreak 2.3.1

[sodface]

We have musl in common. My wlroots version is 0.17.3.

[oblivikun]

im running wlroots 0.17.2, il try updating it

I've actually been switching ttys with those keys a lot recently on my laptop, and it's fast. I'm doing it on my multi monitor desktop and it's a little slow to switch back and forth but it does work.

[sodface]

Well I should say on the desktop it's fast to switch to a different tty but then a bit slow for the Cagebreak session to reappear when I switch back to tty1. By slow though I only mean about 1-2 seconds.

[oblivikun]

still running into that issue

[sodface]

And sway works ok on the same hardware?

[sodface]

Did you back out those key bindings from your config?

[oblivikun]

yes, on sway i can change with the keys, but on cagebreak i have to manually call it with the chvt command

[sodface]

Weird. I'm on my laptop now and it's working fine, same component versions as my desktop.

[oblivikun]

it apears that it may be the C-A key combination that is not being recognized, as i can change ttys by binding L-[1,2,3] to exec sudo chvt (number)

[sodface]

cagebreak/keybinding.c

Line 511 in ace4ff0

keybinding_switch_vt(struct cg_server *server, unsigned int vt) {

There's a couple if's there, one of which might be false?

[oblivikun]

i removed that if statement and im still not able to switch ttys

[sodface]

I don't know if it matters, but I'm starting cagebreak from tty1 (no login manager) and in my .profile I have:

 exec dbus-run-session -- cagebreak -e > cagebreak.log 2>&1

[oblivikun]

im not running cagebreak with socket or dbus, will try that.

[oblivikun]

still no luck

[sodface]

I'm running out of ideas. Sway seems to use the same function to change vt:

https://github.com/swaywm/sway/blob/cc342107690631cf1ff003fed0b1cdb072491c63/sway/input/keyboard.c#L272-L276

But a difference in how the vt number is calculated... not really sure what that's doing.

[oblivikun]

then i will copy what sway does

[sodface]

I guess I should have asked if you started with the example Cagebreak config? Mine has:

definekey top XF86_Switch_VT_1 switchvt 1
definekey top XF86_Switch_VT_2 switchvt 2
definekey top XF86_Switch_VT_3 switchvt 3
definekey top XF86_Switch_VT_4 switchvt 4
definekey top XF86_Switch_VT_5 switchvt 5
definekey top XF86_Switch_VT_6 switchvt 6

[oblivikun]

after applying the logic that sway did, it worked

[sodface]

Hmmm, and your non working config had the above default key bindings?

[oblivikun]

yes

Hi,
Sorry for the long response time. I have two questions that might help us figure out what's going on here:

1. What does pressing ctrl+alt+fn+f1-6 do?
2. You said that "applying the logic that sway did" makes it work. What do you mean by this exactly?

Cheers,
