I have an ASUS EAH3450 (0x95C5:0x1043:0x01F4, Newegg N82E16814121259), Option "HPD" "Off" Option "UseAtomBIOS" "On" - Without any device options, no connected monitors are detected and X doesn't start. - With only HPD Off, the DVI monitor is detected, but the VGA is not. - With only UseAtomBIOS On, the VGA monitor is detected, but DVI is not. - With both, both monitors work.
Please start 'X -logverbose 7' without these options and post the logfile (yes, it will shut down immediately). Also run 'conntest' as described in the README, once per monitor attached.
xorg.conf contains: Section "Device" Identifier "video" Driver "radeonhd" EndSection "X -logverbose 7" output is attached as radeonhd.log For conntest, I ran "rhd_conntest 02:00.0 -s -x 256" for each case: conntest-none.log: no monitors connected conntest-dvi.log: only DVI connected conntest-vga.log: only VGA connected conntest-both.log: both connected While shuffling cables, I remembered that I have a KVM switch on the VGA (duh), so I also did: conntest-vganokvm.log: only VGA connected, no KVM conntest-bothnokvm.log: both connected, no KVM In this case the VGA output is now detected properly, and an Xorg.conf containing just: Section "Device" Identifier "video" Driver "radeonhd" Option "HPD" "Off" EndSection now drives both monitors. I should have tested that earlier, sorry! Is there an option to override detection on VGA?
I still have the flickering problem. Sometimes, using xrandr to toggle the refresh rate between "60.0" and "59.9" makes it less frequent, which makes me suspect a driver issue, but it could be the monitor too, I don't really know.
Could be electrical values. However, if AtomBIOS isn't working for you...
It flickers both with or without AtomBIOS. Sometimes the screen jitters to the right for a split second too. I tried a poweroff and cold boot but it doesn't change. The vesa driver doesn't flicker. If it would help to check DVI voltages or timings on a scope, I can do that, but it will take me a few days. -jim
