Thanks for your info.
1.
Without any xorg.conf file I don't know why it shows
'ati' as main driver in the header section of Xorg.log and
not radeon.
(==) --- Start of built-in configuration ---
Section "Device"
Identifier "Builtin Default ati Device 0"
Driver "ati"
EndSection
Section "Screen"
Identifier "Builtin Default ati Screen 0"
Device "Builtin Default ati Device 0"
EndSection
Section "Device"
Identifier "Builtin Default vesa Device 0"
Driver "vesa"
EndSection
Section "Screen"
Identifier "Builtin Default vesa Screen 0"
Device "Builtin Default vesa Device 0"
EndSection
Section "Device"
Identifier "Builtin Default fbdev Device 0"
Driver "fbdev"
EndSection
Section "Screen"
Identifier "Builtin Default fbdev Screen 0"
Device "Builtin Default fbdev Device 0"
EndSection
Section "ServerLayout"
Identifier "Builtin Default Layout"
Screen "Builtin Default ati Screen 0"
Screen "Builtin Default vesa Screen 0"
Screen "Builtin Default fbdev Screen 0"
EndSection
Shouldn't there be radeon or radeonhd somewhere since this
is a radeon chip set or maybe the drivers are similar?
2.
Using /etc/X11/xorg.conf with only this contents:
Section "Device"
Identifier "Card0"
Driver "radeonhd"
EndSection
I did not observe any differences in performance or errors.
Also there were no difference between using "radeon" or "radeonhd"
The errors I got are:
(EE) Failed to load module "xtsol" (module does not exist, 0)
:
[drm] failed to load kernel module "radeon"
(EE) RADEON(0): [dri] RADEONDRIGetVersion failed to open the DRM
[dri] Disabling DRI.
:
(EE) RADEON(0): Acceleration initialization failed
3.
Moving the three libraries: libdri.so, libdri2.so, libdrm.so.2
had no impact on performance and I got an additional error:
(EE) Failed to load /usr/lib/xorg/modules/extensions/GL/amd64/libglx.so
It looks like extension glx needs to load these files.
Before removing these libraries glx was reported to be successfully loaded.
It's interesting that just scrolling through a text window causes CPU load
to go up to 100%.
I haven't started to view any video yet. I would think that XVideo
or GLX will be needed for this.
and yes I ran into this trap when I was testing earlier:
>> Warning: Do not simply test it via the recommended Xorg -config
>> ~/xorg.conf.new , because the old Ctlr+Alt_Backspace key sequence by
>> default no longer kills the server
I got the Xserver to hang and had to do a hard (power) shutdown.
