[5.16.8][Intel] Kernel breaks higher refresh rates on eDP monitor
Hello,
Doing an upgrade yesterday to get KDE 5.24, I noticed that only 60Hz refresh rate was available for my eDP panel. At first I thought this was a KDE/Wayland issue, but testing X11 and looking at xrandr output it seemed like the issue was further upstream.
I have an MSI GE76 with a 360Hz display. Its an Optimus laptop with Intel/NVIDIA:
00:02.0 VGA compatible controller: Intel Corporation TigerLake-H GT1 [UHD Graphics] (rev 01)
01:00.0 VGA compatible controller: NVIDIA Corporation GA104M [GeForce RTX 3080 Mobile / Max-Q 8GB/16GB] (rev a1)The Intel controller is the default driver of the eDP panel.
The HDMI port which is I believe directly tied in with the NVIDIA card can see the higher refresh rates of my TV. I only see it in xrandr when using PRIME.
Affected kernel: linux-5.16.8.arch1-1-x86_64
Downgrading to linux-5.15.13.arch1-1-x86_64 resolves the issue for me.
XRandr output on 5.15.13:

Re: [5.16.8][Intel] Kernel breaks higher refresh rates on eDP monitor
Sorry, forgot this thread.
https://bbs.archlinux.org/viewtopic.php?id=273676 but was inconclusive.
360Hz is excessively high and i seem to remember some modeline sanity check being too aggressive for even lower frequencies (but in xorg?)
Check your xorg log and system journal whether there's a warning for the mode to be filtered out (the verbatim string in google will then likely yield the offending patch)

Re: [5.16.8][Intel] Kernel breaks higher refresh rates on eDP monitor
Hello,
I have an MSI GE76 with a 360Hz display. Its an Optimus laptop with Intel/NVIDIA:
00:02.0 VGA compatible controller: Intel Corporation TigerLake-H GT1 [UHD Graphics] (rev 01) 01:00.0 VGA compatible controller: NVIDIA Corporation GA104M [GeForce RTX 3080 Mobile / Max-Q 8GB/16GB] (rev a1)
I have an extremely similar specs laptop to yours (Razer Blade 15" Advanced 2021), with those exact graphics devices.
I am experiencing the same issue and downgrading to 5.15.13 did indeed resolve it after nothing else did.
