--- Comment #9 from Kunal Joshi <kunal1.joshi at intel.com> ---
I was able to reproduce the bug.

uname -a
5.3.0-rc5+ #9 SMP Fri Aug 30 10:45:22 IST 2019 x86_64 x86_64 x86_64 GNU/Linux

I am using edp panel which supports two modes 48hz and 60hz.





The command  xrandr --rate 48  successfully ran but still the refresh rate was
60hz,but after running this command i915_display_info shows the mode as "".

Then i tried with igt test *testdisplay,*This test traverses through all
support modes and sets the mode,i gave a delay of 10 seconds so i could ssh on
to the system and check i915_display_info.

I found that both mode were successfully set and we can see it in the attached
files 48hz and 60hz and also the dmesg log.

sudo ./tests/testdisplay -s 10



So i think the problem is with xrandr implementation
