Hi everyone,
I updated my system today:
[2022-06-09T08:40:01+0200] [ALPM] installed libverto (0.3.2-4)
[2022-06-09T08:40:01+0200] [ALPM] upgraded krb5 (1.19.3-1 -> 1.19.3-3)
[2022-06-09T08:40:01+0200] [ALPM] upgraded libgpg-error (1.45-1 -> 1.45-2)
[2022-06-09T08:40:01+0200] [ALPM] upgraded grub (2:2.06-5 -> 2:2.06.r261.g2f4430cc0-1)
[2022-06-09T08:40:01+0200] [ALPM] upgraded libx11 (1.8-1 -> 1.8.1-1)
[2022-06-09T08:40:01+0200] [ALPM] upgraded qt5-base (5.15.4+kde+r146-1 -> 5.15.4+kde+r151-1)
[2022-06-09T08:40:01+0200] [ALPM] upgraded upower (0.99.18-1 -> 0.99.19-1)
After a reboot I couldn't login into any of my accounts anymore. I even created a fresh account in order to exclude any local account settings, which might interfere with any of the above libraries but it still didn't work. The login-manager lightdm is shown but after login the screen either goes black or XFCE's default background image is shown four times in the upper left, upper right, lower left and lower right corner of the screen. The mouse cursor is visible and responds to mouse movements but other than that the screen is "empty" (no icons, etc.). After looking through the above packages I decided that libx11 might be the cause and downgraded it:
[2022-06-09T09:02:35+0200] [ALPM] downgraded libx11 (1.8.1-1 -> 1.8-1)
After that the error disappeared. (I didn't try to downgrade the other suspect qt5-base.) Is this a known bug? Here's my system setup:
$ xrandr

Thank you for the solution! I had exactly the same problem on Desktop and Laptop! On desktop I have nvidia + XFCE, while on laptop I have Intel + XFCE. Both of these were solved by downgrading libx11 to an older version.

No one's the real thing. Some of us just have fewer lies to tell.

Thanks, just rebooted and got your issue, I was looking at the pacman log and suspected libx11. (intel driver here)

Hi,
pfff, I struggled the whole morning with this... Had exactly the same issue.
To add a bit more, this was only happening when logging in on xfce. Since I'm using gdm I could try to login to gnome and that worked fine.

Yes, this is more than likely an XFCE bug! https://gitlab.freedesktop.org/xorg/lib … issues/157
