Half height of the external display (left rotated) remains unlocked.

[invano]

The issue affects the latest release of i3lock and has not been tested on previous releases.

I use i3 and i3lock on xubuntu 14.04 (Trusty Tahr) with 2 displays:

1. Laptop display
2. External display placed as "right of" the laptop display

If the external display is rotated 90° to left, i3lock does not draw its overlay in a good way on it. In particular, the overlay is perfectly drawn on the laptop display but it only covers 50% of the height of the external display.
Since only half of the external display is "locked", i3lock does not completely secure the underlying tiles/windows.

However, as soon as a key is pressed and the password validation routine starts working, the new overlay containing the login animation finally occupies the entire screen.
To have an unsecure lockscreen again it is enough to login with the correct password and then lock the screen again.

What’s the output of i3lock --version (“latest” is not a version number :)) and what’s the output of xrandr?

[Airblader]

Are you running a compositor? Does not running it fix it?

What’s the output of i3lock --version (“latest” is not a version number :))

With latest I mean i3lock 2.7:
i3lock: version 2.7 (2015-05-20) © 2010 Michael Stapelberg

and what’s the output of xrandr?

Where DP2 is the external display rotated.

Are you running a compositor? Does not running it fix it?

No compositor is running but I will check with it as soon as I get the opportunity.

Please run sudo apt-get install xtrace, then use Ctrl+Alt+F1 to switch to a text console, log in, run DISPLAY=:0 xtrace -o /tmp/xtrace.log i3lock -n, use Ctrl+Alt+F7 to switch to X11 (do not enter your password), then switch back and cancel the i3lock process using Ctrl+C.

Then, compress /tmp/xtrace.log using bzip2 -9 /tmp/xtrace.log and provide /tmp/xtrace.log.bz2 please.

[stapelberg]

(If xtrace prints “Error parsing xauth list data”, add the -n flag, i.e. DISPLAY=:0 xtrace -n -o /tmp/xtrace.log i3lock -n)

[invano]

The xtrace log is available here: https://www.dropbox.com/s/2bw2gv5901gguyt/xtrace.log.bz2?dl=0

From the logfile, i3lock creates a 3120x1920 window:

000:<:00b9: 44: Request(1): CreateWindow depth=0x00 window=0x04e00003 parent=0x000000c6
x=0 y=0 width=3120 height=1920 border-width=0 class=InputOutput(0x0001)
visual=CopyFromParent(0x00000000)
value-list={background-pixmap=0x04e00000
override-redirect=true(0x01)
event-mask=KeyPress,KeyRelease,Exposure,VisibilityChange,StructureNotify}

From the xrandr output you provided, that matches up the X server’s root window size:

Screen 0: minimum 8 x 8, current 3120 x 1920, maximum 32767 x 32767

Hence, I think i3lock is behaving correctly here.

I’m not sure why you are running into the problem you’ve described. Could you boot from a live linux distribution and run i3lock there to make sure it’s not something in your setup?
