Thanks Jakob I am one stpe further. Under X I got this:
t...@t500:~/priv/srcxorg/mesa/progs/egl$ INTEL_SOFTPIPE=true
EGL_DRIVER=~/priv/xorg/lib64/dri/EGL_i915.so ld-x ./eglgears
debug_get_option: GALLIUM_TRACE = (null)
debug_get_bool_option: GALLIUM_RBUG = FALSE
get chip id failed: -1
param: 4, val: 0
get fences failed: -1
param: 6, val: 0
debug_get_bool_option: INTEL_SOFTPIPE = TRUE
debug_get_bool_option: INTEL_DUMP_CMD = FALSE
libEGL Warning: Could not retrive kms information
eglgears: EGL version = 1.4
eglgears: EGL_VENDOR = Mesa Project
eglgears: eglGetModesMESA failed!
Is there any way to run EGL under X?
From the command line (tty1, resolution is native 1680x1050) I got an
assertion at intel_be_device.c:198 since the height, 1050 is not a
multiple of 8. Uncommenting the assert lets me run eglgears.
Thanks,
Kristof
