I thought I might be working through my last few big problems, but
instead I found another one.
After installing Lubuntu Quantal on a newly formatted disk and setting
up LTSPsome weeks ago, I have been working only with a certain
two-machine test setup. In contrast to past troubleshooting, I have not
been swapping in multiple server or client machines.
But to address something I was working on, I tried a different client,
and this one failed to boot altogether. Then I tried a couple more
different clients (different makes/models), and they had the same
behavior. That behavior is that after the client displays the blue
splash screen, which then drops to black-and-white (normal behavior, I
think), it then goes to a blank (black) screen. It does not display the
GUI login screen.
If in lts.conf I set SCREEN_07=shell, then I can successfully log in to
a shell. I also see there among the on-screen boot messages "Starting
load fallback graphics devices [fail]."
The last entry in dmesg also refers to the above failure.
The only client that works displays a (boot) message on/through the
splash screen: "lpc_ich 0000:00:1f.0: I/O space for GPIO uninitialized."
Anyone recognize this problem?
