you need 2.6.34.
Now at 2.6.34-rc3
Good.
Some headway. The radeon driver as well as drm_kms_helper and a number
of other things are loaded and associated with the radeon driver.
However early in the boot process - I think when the modeset happens
because my Intel i915 does this also - the screen goes black. On the
Intel the screen shifts to a smaller font. Here I'm just seeing a
blank screen so far. The monitor can't find the signal and then turns
off.
When you boot, the BIOS is using an old VGA text mode. The Linux
kernel, at some point fairly early in the boot process, will now enable
the new DRM framebuffer. The screen should go black momentarily, but
should come back quickly in a much higher resolution text mode as the
kernel continues to boot.
Can you mention what sort of cable connects your video card to your
monitor? Is it VGA? DVI? HDMI? DisplayPort?
I have had black screen issues with the VGA connector on my HD 5750.
DVI works perfectly for me. HDMI works almost perfectly, but with some
sort of issue with timings so that I end up with a pink/purple vertical
line on the left side of my monitor.
Independent of actually getting graphics should we be able to switch
fonts at this point?
Needless to say, it should have been working and you shouldn't have
gotten the black screen. No intervention on your part -- say, to change
fonts or resolution -- should be required.
I can't find a package called libdrm_radeon in portage. Is this
possibly part of xorg-server-1.7? I do have libdrm and xf86-video-ati
but neither show a kms flag. Again maybe that's on newer versions?
(I'm not a Gentoo user; take the following with a grain of salt.)
You need a libdrm built with radeon DRM support enabled. Neither libdrm
nor xf86-video-ati will have their package names modified to indicate
KMS or Radeon support.
You should find out what documentation is installed on your system with
those packages. For example, if libdrm was built with radeon support,
the docs packaged with libdrm will probably indicate that explicitly.
If you don't know where to find the package documentation on your
system, is their a forum or mailing list for Gentoo that you know of
where you could ask questions? Especially with Gentoo, I'm sure you
would get immediate responses letting you know how to get libdrm with
radeon support enabled.
If the version number on xf86-video-ati is 6.12.191 or higher, it will
have at least some Evergreen support. Best would be version 6.13, though.
I'm not against going to a testing xorg-server but a number of Gentoo
people are having trouble so I wouldn't go there without a good
reason. Keep in mind this is a brand new machine. I have nothing
invested in terms of work on it so most anything is OK at this point
if it's going to produce positive results. I'll investigate unmasking
the newer stuff, but I don't see libdrm_radeon anywhere as of yet.
If the "testing" xorg-server is 1.7.5 or higher, you should try it --
especially if you really are in the experimental frame of mind that you
claim to be! The main differences between version 1.7 and later
versions like 1.7.5 and 1.7.6 were bug fixes; my own experiences have
been very positive with these latest versions. (Obviously, there are
plenty of folks out there who are having very real problems with the X
server, though, so I'm certainly not guaranteeing that later versions
will work as good for you as they have for me!)
Good luck,
Dave W.
