Created attachment 137408 [details]

And it helps if I actually attach the log file.. doh

Comment 2 Adam Jackson 2006-09-29 17:51:13 UTC
rpm -q xorg-x11-drv-ati

I suspect the DAC hack added in -2 is turning off your output when it shouldn't.

Comment 3 David Nielsen 2006-09-29 18:07:17 UTC

I don't get that.. -2 should be the most recent one.. -11 ?? 

Comment 4 David Nielsen 2006-09-29 18:13:53 UTC
okay I removed the driver and reinstalled the -2 one released today, same problem.

Comment 5 Adam Jackson 2006-09-29 18:25:31 UTC
Try this test RPM:


(For the curious: changes the if (!bConnected) check in
radeon-6.6.2-dac-fix.patch to if (0), which should prevent us from turning off
the DAC, which would be one obvious source of black screens.)

Comment 6 David Nielsen 2006-09-30 18:04:24 UTC
well I tried booting after todays update since I saw an update from Dan Walsh to
selinux-policy that simply read "Fix rhgb". Regardless, this time rhgb pops. Can
anyone confirm the now non-brokenness of the behaviour?

Comment 7 Adam Jackson 2006-10-02 15:25:17 UTC
dwmw2 reports that the workaround in comment #5 works for him.  Adding to
6.6.2-4, and closing.
