[gentoo-user] kwin opengl compositing w/ nouveau?

[Doug Hunley]

Me again ;)

I just ran 'startx' on my machine for the first time in a dog's age
and had to switch the rendering engine to XRender from OpenGL to get a
usable desktop (couldn't see the desktop. was a bunch of black
squares). I'm not sure what changed, and the online wiki/forum  pages
I just spent two hours reading were stale and of little help. Anyone
see anything stupid herein:

At this point, I don't care if it's OpenGL or OpenGL ES (kwin_gles)
that we get working.. I just want to use something 'better' than
XRender again (it lags badly for me)

Thanks!

Two things come to mind, given some recent trouble I've had on the
radeon side of the coin here, and with an intel system or two in the
past. The DRM related drivers seem to be prone to misbehaving when
they're not configured as modules. I haven't managed to sort out why,
so you may see if a change there helps, though it'll likely cause mode
changes throughout the booting process. The second thing that comes to
mind is that you don't include any relevant entries from glxinfo
(glxinfo | grep ender) or Xorg.?.log (notably anything flagged as an
error, 'grep EE /var/log/Xorg.0.log' grabs that, plus a bit of cruft),
notably from a session where things aren't working properly, as the
majority of issues trace back to direct rendering being disabled due
to some incompatibility that gets noted in the log (often in
delightfully cryptic prose).

That's um.... ok. I guess I can try that

I'll do this and get back w/ you. Might be a few days, as I rarely
have occasion to 'startx' on this box

thx!

I converted nouveau to a kernel module:
$ lsmod
Module                  Size  Used by
nouveau               579746  -2
cfbfillrect            12485  -2
cfbimgblt              12313  -2
cfbcopyarea            12313  -2
drm_kms_helper         27209  -2
ttm                    57762  -2

switched the kwinrc to OpenGL, ran startx. KDE loaded (I saw the
splash screen and heard the startup noise) but then nothing was shown
on the desktop (so I couldnt run glxinfo as I couldnt see anything)

Ive attached Xorg.0.log and xsession-errors herein. Bad.tgz has
versions of these files from OpenGL whereas good.tgz has versions from
XRender.

FWIW, the only 'EE' in the Xorg log is missing 'fb' and 'vesa' modules

Also  I do not have an xorg.conf if that makes a difference
