Description Ihar Areshchankau 2020-01-18 18:00:28 CET

Description of problem:
Screensaver doesn't accept keyboard input.

Version-Release number of selected component (if applicable):
Linux localhost 5.4.12-desktop586-1.mga7
xscreensaver-5.42-1.mga7
libxscrnsaver1-1.2.3-3.mga7
xscreensaver-common-5.42-1.mga7
xfce4-screensaver-0.1.8-1.mga7
mageia-theme-screensavers-7.0-2.mga7

How reproducible:
Wait for screen-lock timeout and try to unlock the screen.
On fresh installation this works well. The trouble appears after updating the system.

Steps to Reproduce:
1) Install Mageia Linux using Mageia-7.1-Live-Xfce-i586.iso, add an unprivileged user with a not empty password ().
2) Update the system.
# urpmi --auto-update
# reboot
3) Repeat 2nd step until the system will up to date.
4) Boot the updated system up.
5) Login as unprivileged user.
6) Run shell.
7) Leave the system in peace until screen will be locked (over 10 min default).
8) Move a mouse and click buttons - unlock screen appears.
9) Try enter password - input doesn't accepted.
10) Press [Unlock] button - Checking... Incorrect password message appears.
11) Press [Switch User] button and enter password - the system unlocked.
12) Try enter some commands to the running shell - input doesn't accepted.

Remark: New icon "Screensaver" appears in "Settings" window near by "XScreenSaver" after the system upgrading.

This looks the same as bug 25008; can you please look at that to see whether you think it is the same thing. If so, this can be marked as a duplicate.
25008 is extremely long, so here are some comments that seem most useful:
 0, 18, 33, 36.
The two bugs have in common:
 i586, Xfce, the problem appears *after updating the system*.

I would recommend:
- explore the possibility that >1 screensaver/lock is running (c.33)
- then disable every screensaver/lock you can find.

It seems that there are two screensavers at one time...

(In reply to Lewis Smith from comment #1)
Thank you for recommends! I'm trying c.33 now and will report for results. It seems that my issue really is a duplicate.

Comment 4 Ihar Areshchankau 2020-01-19 19:46:47 CET

$ ps alx | grep screensaver
	0:00 xscreensaver -no-splash
	0:04 xfce4-screensaver
	0:01 chbg -xscreensaver -mode smart (...)

After uninstalling first screensaver the system works well:

# rpm -e xscreensaver-5.42-1.mga7
# rpm -e xscreensaver-common-5.42-1.mga7

Thank you!

Thank you for your +ve attitude, the screenshot (a picture is worth a thousand words), the 'ps' output, and your effective remedial action.
