Hi Christophe,

Actually i have the same problem after update guix pull & guix reconfigure to 
the last gnome version. 


Looking to /var/log/message in real time using tail -f /var/log/messages, i 
found there is an ugly segfault after more or less 1 minute in one of gds 
service 
(/gnu/store/qmjsxby7knqmy4h0rr9ahjm6713f150n-gnome-settings-daemon-47.2/libexec/gsd-usb-protection)
 launched by gnome at startup : gsd-usb-protection .gsd-ubs-protect , 
org.gnome.settingsDaemon.USBProtection.desktop ... This service is not 
accessible from dconf editor of gsettings

I found that it's possible to desactivate this gsd-usbprotector gnome service 
by modifying the corresponding gnome.session file : 


RequiredComponents=org.gnome.Shell;org.gnome.SettingsDaemon.A11ySettings;org.gnome.SettingsDaemon.Color;org.gnome.SettingsDaemon.Datetime;org.gnome.SettingsDaemon.Housekeeping;org.gnome.SettingsDaemon.Keyboard;org.gnome.SettingsDaemon.MediaKeys;org.gnome.SettingsDaemon.Power;org.gnome.SettingsDaemon.PrintNotifications;org.gnome.SettingsDaemon.Rfkill;org.gnome.SettingsDaemon.ScreensaverProxy;org.gnome.SettingsDaemon.Sharing;org.gnome.SettingsDaemon.Smartcard;org.gnome.SettingsDaemon.Sound;org.gnome.SettingsDaemon.UsbProtection;org.gnome.SettingsDaemon.Wacom;org.gnome.SettingsDaemon.XSettings;


BUT ... this is a readonly file in /gnu/store, so i'm actually blocked. I don't 
know how to modify this file to remove org.gnome.SettingsDaemon.UsbProtection

I guix rollback to go back to the previous working gnome version :(

Best regards,
Src.
