Result of strace -e inject=prctl:error=ENOSYS /usr/lib64/libexec/kscreenlocker_greet --testing

This shows the lockscreen and allows to unlock via password.

That means it's most likely the sandbox. To find out which syscall got blocked, please run: strace -Z /usr/lib64/libexec/kscreenlocker_greet --testing -- You are receiving this mail because: You are on the CC list for the bug.

After reboot I did several standby/unlock cycles - smooth as it used to be. Will the fix go into the next tumbleweed update ? Amazing response! Keep the good work going!

The issue is that this is a side effect of an OpenGL issue, most likely with the proprietary driver and probably related to suspending. It's not unlikely that in the case where kscreenlocker fails, other applications also misbehave.

I do also get problems kwin compositing after suspend now. It works fine until it restarts, but then OpenGL compositing wont work at all. When running it in a terminal I get: qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 180, resource id: 251658247, major code: 20 (GetProperty), minor code: 0 qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 181, resource id: 251658247, major code: 20 (GetProperty), minor code: 0 QGLXContext: Failed to create dummy context No provider of glXCreateContextAttribsARB found.

Please open a separate bug report for that, against the Nvidia driver. -- You are receiving this mail because: You are on the CC list for the bug.
