Created attachment 137408 [details]

And it helps if I actually attach the log file.. doh
Comment 2 Adam Jackson 2006-09-29 13:51:13 EDT
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 14:07:17 EDT

I don't get that.. -2 should be the most recent one.. -11 ?? 
Comment 4 David Nielsen 2006-09-29 14:13:53 EDT
okay I removed the driver and reinstalled the -2 one released today, same problem.
Comment 5 Adam Jackson 2006-09-29 14:25:31 EDT
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 14:04:24 EDT
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 11:25:17 EDT
dwmw2 reports that the workaround in comment #5 works for him.  Adding to
6.6.2-4, and closing.
