dmesg

Hi, 

My system has an intel igpu and dedicated AMD gpu. If I want to render with the
intel GPU, it does not work. If I try DRI2 and try to set the offloader and
sink, I get the following error from xrandr:
X Error of failed request:  BadValue (integer parameter out of range for
operation)
  Major opcode of failed request:  139 (RANDR)
  Minor opcode of failed request:  34 (RRSetProviderOffloadSink)
  Value in failed request:  0x46
  Serial number of failed request:  16
  Current serial number in output stream:  17


If I use DRI3, and I try DRI_PRIME=1 glxinfo -B, I get the following error:
libGL error: Different GPU, but blitImage not implemented for this driver
libGL error: failed to load driver: i965

and glxinfo displays information about my AMD gpu.


dmesg is attached.

Please let me know if you need anything else.

Thanks,
sarnex
