Three-screen layout only works when applied for a second time about autorandr

[phillipberndt]

What's the output of autorandr --debug --dry-run -c before the first run?

If you reorder the activation order in the output, does one work right away?

[siwyd]

Sorry for the delay, didn't have time before to test this.

This is the output of first changing to 'mobile' (only laptop screen), then trying to activate the 3-monitor output. Changing to mobile is no problem. Then, on the first go, you can see 'configure crtc 1 failed'. On the second go, it's working.

I'll try and reorder the outputs in the profile and give feedback.

Okay, so I managed to make it work by rearranging the config:

This works:

output eDP1
off
output DP1
off
output HDMI1
off
output HDMI2
off
output VIRTUAL1
off
output DP1-1
mode 1920x1080
pos 0x0
rate 60.00
output DP1-2
mode 1920x1080
pos 1920x0
rate 60.00
output DP1-3
mode 1920x1080
pos 3840x0
rate 60.00

And this works as well:

output DP1
off
output HDMI1
off
output HDMI2
off
output VIRTUAL1
off
output eDP1
off
output DP1-2
mode 1920x1080
pos 1920x0
rate 60.00
output DP1-1
mode 1920x1080
pos 0x0
rate 60.00
output DP1-3
mode 1920x1080
pos 3840x0
rate 60.00

eDP1 is my laptop's display by the way. Seems like a timing related issue. Moving the turning off of the laptop display to the top seems to fix it some how. Despite the command working, it is actually still giving an error:

xrandr: Configure crtc 0 failed
Failed to apply profile 'work' (line 610):
  Command failed: xrandr --output DP1-2 --gamma 1.0:1.0:1.0 --mode 1920x1080 --panning 0x0 --pos 1920x0 --rate 60.00 --reflect normal --rotate normal --output DP1-3 --gamma 1.0:1.0:1.0 --mode 1920x1080 --panning 0x0 --pos 3840x0 --rate 60.00 --reflect normal --rotate normal (line 610)
This appears to be a bug. Please help improving autorandr by reporting it upstream.

Maybe it suffices to retry the failed command after waiting some time? I just pushed the retry_commands branch, please give it a try..

[siwyd]

Awesome! Will try it tomorrow when I have access to the 3-screen setup. Feedback soon!

[phillipberndt]

FYI, @telefax reports in #48 that the branch works for him.

[siwyd]

Thx for the update, Phillip. I've tried the new branch, but for some reason it wasn't working just yet when docking my laptop. By not working I mean the behaviour was similar to before. I need a bit more time to do some debugging. I will try to come to work early some time to try out some things.

[phillipberndt]

Alright, take your time. I'll leave this open/unmerged until then. (Maybe it suffices to increase the sleep time, or add a second retry?)

[siwyd]

Yeah, I did that, but it didn't seem to have any positive effect.
Unfortunately it's a week ago, and I didn't document my findings properly
:) Gotta try all that stuff again in a organised manner.

Hey Philip,

I'm incapable of continuing debugging this at the moment, I'm gonna go ahead and close it at the moment. Anyway, @telefax was helped by this report and bugfix so that's a good thing :) Thanks for your effort.
