HW = Chipset: "ATI Radeon HD 4250 " (Chipset = 0x9715)

Config is mostly taken from a working amd64 + radeon system.
linux-firmware is installed. No errors or warning in the the xorg
logs, but startx returns a blank screen on both the VGA and HDMI
outputs. It also fails with no xorg.conf. There's no process called X
or anything related to X, if i ssh in from another machine and run
'pgrep -lf X' as root.

When using fglrx;
proxy adam # tail Xorg.0.log
[ 458.503] (II) fglrx(0): Desc: ATI FireGL DRM kernel module

Try with this simplified xorg.conf:

Section "Device"
Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
#Driver "radeon"
EndSection


You can toggle video drivers also and tell what happened. By the way, you
realise you also need to setup correct kernel modules and disable
conflicting ones when changing from fglrx to radeon, right?

Really - i thought changing the X driver was all that was required. Is
that do with with KMS?

Anyway, i think i'll focus on just using fglrx as its what i use
successfully on my laptop.

FYI, this is fixed. I ran 'strace startx > startx.strace.out 2>&1' and
this showed;
/usr/bin/X: symbol lookup error:
/usr/lib64/xorg/modules/drivers/fglrx_drv.so: undefined symbol:
GlxInitVisuals2D

Which means that i forget to eselect opengl set 1, though it wasn't
logged to Xorg.0.log (so it was logged to STDOUT, but i couldn't see
that as the screen was blank).

Then after fixing that;
which: no keychain in
(/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/usr/x86_64-pc-linux-gnu/gcc-bin/4.5.3)
/etc/X11/xinit/xinitrc: line 63: exec: xterm: not found
/etc/X11/xinit/xinitrc: line 61: xterm: command not found
xinit: connection to X server lost

So i emerged keychain and xterm and it now works. Of course i didn't
need xterm as i'm running gnome, so i could have just kicked that off
instead.
