lightdm-webkit2-greeter 2.2.5-1 lockscreen don't show unlock screen

[alexwbaule]

Hello,

I have a Nvidia video card, with Nvidia drivers.

If i lock the desktop, when i try to unlock it, only the mouse is showed. I enabled the greeter debug, and got this in the seat0-greeter.log

Using the lightdm-gtk-greeter, this error don't happens.

(WebKitWebProcess:1927): Gdk-ERROR **: 22:46:16.862: The program 'WebKitWebProcess' received an X Window System error. This probably reflects a bug in the program. The error was 'BadWindow (invalid Window parameter)'. (Details: serial 167 error_code 3 request_code 155 (NV-GLX) minor_code 4) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)

There is another file, or some kind of debug to enabled to help find some solution ?

Tks.

Is it an abandoned project?

I'm unable to reproduce the issue using NVIDIA card and drivers. This kind of thing is extremely difficult to debug remotely. Which distribution are you using? If not Antergos or Arch, could you provide the versions of the following packages that you have installed?

• webkit2gtk
• gtk3
• lightdm

[alexwbaule]

Im Using Antergos.

What kind of information you need ? I Can provide to you. My Nvidia is: 01:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce 210] (rev a2)

Im using the Nvidia 340.107-29 driver version, from pacman.

I'm using the same packages as you on my system including NVIDIA drivers and yet I cannot reproduce the issue. Could you let me know which desktop are you using and what steps exactly do you take to reproduce the issue. Meaning, what exactly do you do to lock the system, what happens next, what do you do to unlock it and what happens after that?

[alexwbaule]

Hi @lots0logs , sorry about the delayed.

I have a Core i7 2600k, with 8GB RAM, with antergos about 3 or 4 years, up to date.

My steps to do a lock screen, is using the keyboard shortcut or a lock using the menu button from Gnome. If i left the PC in idle , and the lock occurs by timeout, i got stuck too in a black screen.

I will provide later, the packages version, that you asked.

Hi, I'd like to add that I am experiencing a similar issue that I suspect may be related. Whenever I do a lockscreen my screen turns blank and I can see my monitor auto cycling through its input ports.

However, when I move my mouse or press a key the video output is enabled again and I can see the lockscreen and log in normally.

My Nvidia is 01:00.0 VGA compatible controller: NVIDIA Corporation GM204 [GeForce GTX 980] (rev a1)

I'm currently using the nvidia 415.27-4 drivers from pacman.

I'm thinking this may be a light-locker or lightdm issue since running light-locker-command -l results in the same blank screen. I get the same result by running dm-tool lock.

However, running dm-tool switch-to-greeter produces the desired behavior, taking me to the login/lockscreen without a blank screen.
