16 I converted nouveau to a kernel module:
17 $ lsmod
18 Module Size Used by
19 nouveau 579746 -2
20 cfbfillrect 12485 -2
21 cfbimgblt 12313 -2
22 cfbcopyarea 12313 -2
23 drm_kms_helper 27209 -2
24 ttm 57762 -2
26 switched the kwinrc to OpenGL, ran startx. KDE loaded (I saw the
27 splash screen and heard the startup noise) but then nothing was shown
28 on the desktop (so I couldnt run glxinfo as I couldnt see anything)
30 Ive attached Xorg.0.log and xsession-errors herein. Bad.tgz has
31 versions of these files from OpenGL whereas good.tgz has versions from
32 XRender.
34 FWIW, the only 'EE' in the Xorg log is missing 'fb' and 'vesa' modules
36 Also I do not have an xorg.conf if that makes a difference
