Public bug reported:
I haven't been able to get DRI to work with this card and the ati driver
despite the fact that it's said to be supported.
glxinfo | grep "direct rendering" gives
direct rendering: No (If you want to find out why, try setting
LIBGL_DEBUG=verbose)
LIBGL_DEBUG=verbose glxinfo gives no additional information (verbose
hint seems to be ignored)
lspci lists two PCI display devices as unknown devices:
01:00.0 VGA compatible controller: ATI Technologies Inc Unknown device 5657
01:00.1 Display controller: ATI Technologies Inc Unknown device 5677
Xorg.0.log makes so mention of any of these being recognized as an X700 which
is what the card is supposed to contain.
The only thing close is the excerpt below but that corresponds to one of the
above devices and not what I was expecting anyway.
(WW) RADEON: No matching Device section for instance (BusID PCI:1:0:1) found
(--) Chipset ATI Radeon X550XTX (RV370) 5657 (PCIE) found
Then I'm told later in the log that DRI has been disabled and that there are no
DRI capable screens.
The full xorg log is attached.
