Hello, I appear to have reproduced this issue on Kali rolling with a newer xbrlapi/brltty package version than the original report.
Environment: - Distribution: Kali rolling - Desktop environment: XFCE - Display manager: LightDM - Session type: X11 - xbrlapi package version before workaround: 6.9.1-1 - Package state before workaround: xbrlapi installed, brltty not installed - Relevant Xsession script: /etc/X11/Xsession.d/90xbrlapi Symptom: The system reached graphical.target quickly, but after graphical login the desktop appeared to stall before XFCE’s core desktop clients launched. Boot timing was not the issue: Startup finished in 3.151s (kernel) + 5.686s (userspace) = 8.838s graphical.target reached after 5.685s in userspace Before removing xbrlapi, the graphical login/session timeline showed: 12:18:12 lightdm --session-child started 12:18:16 gnome-keyring-daemon started 12:18:16 xfce4-session started 12:20:31 xfwm4 started 12:20:31 xfsettingsd started 12:20:31 xfce4-panel started 12:20:31 xfdesktop started So xfce4-session started, but the core XFCE desktop clients did not launch until approximately 135 seconds later. After purging xbrlapi and rebooting, the same session startup path became fast: 12:33:00 lightdm --session-child started 12:33:03 gnome-keyring-daemon started 12:33:03 xfce4-session started 12:33:04 xfwm4 started 12:33:04 xfsettingsd started 12:33:04 xfce4-panel started 12:33:04 xfdesktop started So the delay collapsed from approximately 135 seconds to approximately 1 second. This appears consistent with the earlier finding in this bug: xbrlapi can block the Xsession startup path when brltty is absent. Additional details: - /etc/X11/Xsession.d/90xbrlapi was present before the workaround. - The xbrlapi package was installed, but brltty was not. - Purging xbrlapi removed the startup delay. - The issue was observed with XFCE under LightDM/X11 rather than GNOME/GDM, but the symptom and workaround appear to match this bug closely. I am adding this as a data point because the issue appears to still affect newer package versions, at least in Kali rolling, which imports the Debian brltty/xbrlapi packaging. Regards, earthenvessel
