Google Chrome OS 0.8.75.0 (Official Build bccc7c1d) dev x86 test Google Chrome 7.0.540.0 (Official Build 61029) WebKit 534.10 V8 2.4.

Please specify Area- Profile picture screen

What steps will reproduce the problem? 1. Sign in as new user 2. When the take profile picture is shown up, Ctrl + Alt + l 3. Click on sign out on the screen lock screen. 4. Login as the use

What is the expected output? Should not show a crash. or should not allow user to lock the screen during the profile picture screen

What do you see instead? Chrome shows the restore on crash bar. Crash on signing in valid use

avayvod@, please investigate the crash part of this bug, we want to keep the screen lock functional

Ctrl + Alt + l stopped working for me on yesterday's build (both on image screen and afterwards). Is it a known issue?

Ok, Ctrl + Alt + l does work, guess it was due to slowness of the UI. However there's no sign out button anymore - login screen is shown with logged in user pad activated and I only can enter user's password. At this point debug Chrome crashes with the following stack trace:

Ctrl+Alt+L doesn't work for me. What I observed and described in #4 was our testing shortcut which works in Debug mode and shows login screen.

ctrl-alt-l has been removed and replaced with short press of power button. You also need to enable screen locker in settings.

I looked at the stack trace above, and it looks like what you've got is not screen locker. ScreenLocker uses ScreenLocker::OnLoginSuccess but not ExistingUserController::OnLoginSuccess. I don't know what happened, but looks like you've got login screen instead of screen locker.

Anyway, I just tested with TOT build from yesterday.

When I pressed power button, I've got the screen locker. I could unlock the screen, but camera stopped working. Log message had following message.

camera.cc(3)] VIDIOC_QBUF failed. errno: 22, Invalid argument camera.cc(318)] Calling StopCapturing when capturing is not started.

Singout button indeed caused the crash tab, but I've got the same crash tab when I shutdown straight (pressing powerbutton longer).

Bulk move to R9.x

Mitsuru, could the crash bar be related to sign out before Chrome browser actually appears? I don't see any process crash except for Chrome shutdown when sign out on profile picture screen. However, since Chrome hasn't fully started actually, it could think it had crashed upon the next start even if it was shutdown normally during sign-out.

Landed as r68344 on ToT.

Issue 9776 has been merged into this issue.
