HD3850 Xorg log

On both X1600pro and HD3850 AGPs switching VT or quitting X will result in a blank but functioning VGA console, CRT monitor will go into standby.

Does not happen with radeonhd/vesa/fglrx drivers.

On the X1600 switching back to the X VT would revive the monitor - this does not work with the HD3850.

Running the vesa driver first totally fixed the problem for the X1600, but although it fixes the vga console on switch/quit for the HD3850 it does not fix the loss of display when switching back to X with <ctrl> <alt> <F7>.

The monitor goes in and out of dpms standby OK with both cards.

bash-3.2$ dmesg | grep -i vga
Console: colour VGA+ 80x25

I guess means I am not using any vesa/radeonfb.

If I connect svideo TV out on the HD3850 I do not loose that display when the monitor is not displaying console.

The commit - "Fix console switch on R500" fixes the vga console issue for me.

If I still had the R5xx then I expect it would totally OK.

I still have the RV670 problem that after switching to a console I get a black display when switching back to the X VT.

The monitor remains on and X is fully functional AFAICT.

Maybe this should be filed as a separate R600 bug and this one closed?

Must have forgotten to close this one, as I haven't seen this for ages.
