I'm guessing you're hitting some dual mode adapter limit.

Please file a bug over at [1], add drm.debug=14 module parameter, and
attach dmesg from boot to hitting the issue.

Dunno if I can 'help' get everything going - - - - but I do have some

Start up a terminal as your user and run $ xrandr --verbose and then if

Intel UHD resolutions

2021-09-10 Thread Randy Dunlap

Hi,

I would like to use QHD resolution (2560x1440) with my shiny new
computer and display. That resolution works if I boot Windows 10
(cough).

What do I need to do to use that resolution in Linux?

I first tried openSUSE 15.3 (kernel 5.3.18-59.19-default)
then I build a v5.14 kernel and tried that.
Both of them max out at FHD (1920x1080).

I am booting with "i915.force_probe=4c8a" on the kernel command line.

My desktop is XFCE4.

CPU is:
processor   : 0
vendor_id   : GenuineIntel
cpu family  : 6
model   : 167
model name  : 11th Gen Intel(R) Core(TM) i9-11900 @ 2.50GHz

microcode   : 0x40
