Description David Zeuthen 2008-04-24 16:59:24 EDT
This is with rawhide as of today (Thu Apr 24 2008)


using Intel 965 and an ADD2 dual DVI output card driving two 1680x1050 monitors.
X.org conf file is stock (no DRI2)

$ LIBGL_DEBUG=verbose glxinfo 
name of display: :0.0
libGL: XF86DRIGetClientDriverName: 1.9.0 i915 (screen 0)
libGL: OpenDriver: trying /usr/lib64/dri/i915_dri.so
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 4, (OK)
drmOpenByBusid: Searching for BusID pci:0000:00:02.0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 4, (OK)
drmOpenByBusid: drmOpenMinor returns 4
drmOpenByBusid: drmGetBusid reports pci:0000:00:02.0
libGL error: drmMap of framebuffer failed (Invalid argument)
libGL error: reverting to (slow) indirect rendering
display: :0  screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)

Maybe this is related to bug 444068.

Actually it's G33, not 965.

Bah, hardware limit is 2048 and upstream hasn't worked around that yet and
probably never will.
