I am trying to reinstall Debian Buster/Testing on a Samsung NC110 netbook after installing a new hard disk. I have got as far as installing the base system and the packages for xfce. Now when I try to boot I get past the grub screen, put in the password for the encrypted disk, the boot appears to proceed normally until the desktop manager login screen should appear then the screen goes black and the keyboard becomes unresponsive.
I get the same symptoms using a different desktop manager and I get the same lock up if I use startx. The system has worked fine for a long time up to last July (i.e. 2018). The system is not crashing, lightdm goes into this loop: systemd[1]: Starting Light Display Manager lightdm[2822]: Could not enumerate user data directory /var/lib/lightdm/data: Error opening directory '/var/lib/lightdm/data': No such file or directory systemd[1]: Started Light Display Manager systemd[1]: lightdm.service: Main process exited, code=exited, status=1/FAILURE systemd[1]: lightdm.service: Failed with result 'exit-code'. systemd[1]: lightdm.service: Service RestartSec=100ms expired, scheduling restart systemd[1]: lightdm.service: Scheduled restart job, restart counter is at <>. systemd[1]: Stopped Light Display Manager The only errors that show in Xorg.0.log are: [ 420,876](EE) modeset(0): [DRI2] No driver mapping found for PCI device 0x8086 / 0x0be1 [ 42.877] (EE) modeset(0): Failed to initialize the DRI2 extension I.e. the graphic controller is a VGA compatible controller: Intel Corporation Atom Processor D2xxx/N2xxx Integrated Graphics Controller (rev 09) Questions, for a start: 1. What is supposed to provide the mapping for PCI device 0x8086 / 0x0be1? 2. Is this error likely to be causing the UI to lock up?
