Bug#390739: blank screen (no output) with mga g400
Package: xserver-xorg
Version: 1:7.1.0-1
Severity: important
I'm using an MGA G400, and with the new update to xorg 7.1, my screen
suddenly stopped working. I can switch to the console at vt1, and the
screen comes back. And X appears to be running fine (all the processes
look ok, and I can hear WMMail make noise when mail comes in), but
when I'm on vt7, the monitor reports "no input signal" and nothing is
visible. Keyboard and mouse input seem to be fine, although it's hard
to tell when you can't see anything, but I can use ctrl-alt-bksp to
kill the Xserver. It all worked fine with 7.0, and nothing (that I
know of) has changed, other than the Xserver version.
I've tried reconfiguring without success. I'm generally pretty good
at figuring out odd X server problems, but this one has me stumped.
At this point, I'm pretty sure this is a bug, and not misconfiguration
-- though I'd be happy to be proved wrong. Anyway, I'm completely
without a usable X at the moment. Help!
One thing that might be relevant: I tried reconfiguring with
autodetect, and it seemed to want to use the on-board SiS controller
(piece of junk) on my motherboard rather than the G400. I'm wondering
if it's still somewhat confused even with the manual configuration.
But it used to work just fine!
I'll happily provide any log files or other information that isn't
automatically attached to this report, if it will help. Just let me
know what you want.
TIA
