Comment # 18 on bug 1208239 from Patrik Jakobsson

Hi Luca,
Again, sorry for they late reply.

From your logs I can see that the Intel driver is properly loaded. I'm not sure
if the benchmarking numbers are sane or not since I don't have a similar system
to compare with. intel-gpu-top shows an idle GPU but perhaps that is because
you didn't have a GPU load running when capturing the output.

Since this bug is about HDMI not being properly recognized I think you should
file a separate bug for the performance issues. The reason HDMI was not
properly recognized at first was that 15.4 didn't support ADL-P. And the
problem with 15.5 was a bad cable.

I think we can close this bug. Please reopen if you feel differently.
