I can't use Wayland yet due to an app compatibility issue: JetBrains IDEs (ex: IntelliJ) text is blurry, hurts eyes (https://youtrack.jetbrains.com/issue/IDEA-218458).

I suspect it is caused by oversampled screens (fractional scaling) not fitting into the maximum framebuffer size of 16384x16384, as evidenced by the following xrandr(1): $ xrandr | awk '/^[^ ]/ && $2 != "disconnected"' Screen 0: minimum 320 x 200, current 16384 x 4320, maximum 16384 x 16384 eDP-1 connected 5112x3195+0+0 (normal left inverted right x axis y axis) 366mm x 229mm DP-2 connected primary 7680x4320+5112+0 (normal left inverted right x axis y axis) 597mm x 336mm DP-3 connected 7680x4320+12792+0 (normal left inverted right x axis y axis) 597mm x 336mm ProblemType: Bug DistroRelease: Ubuntu 23.04 Package: xserver-xorg 1:7.7+23ubuntu2 ProcVersionSignature: Ubuntu 6.2.0-20.20-generic 6.2.6 Uname: Linux 6.2.0-20-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia zfs zunicode zavl icp zcommon znvpair .proc.driver.nvidia.capabilities.gpu0: Error: path was not a regular file. .proc.driver.nvidia.capabilities.mig: Error: path was not a regular file. .proc.driver.nvidia.gpus.0000.01.00.0: Error: path was not a regular file. .proc.driver.nvidia.registry: Binary: "" .proc.driver.nvidia.suspend: suspend hibernate resume .proc.driver.nvidia.suspend_depth: default modeset uvm .proc.driver.nvidia.version: NVRM version: NVIDIA UNIX x86_64 Kernel Module 525.105.17 Tue Mar 28 18:02:59 UTC 2023 GCC version: ApportVersion: 2.26.1-0ubuntu2 Architecture: amd64 CasperMD5CheckResult: unknown CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Fri Apr 21 18:51:29 2023 DistUpgraded: 2023-04-20 13:31:05,017 DEBUG Running PostInstallScript: '/usr/lib/ubuntu-advantage/upgrade_lts_contract.py' DistroCodename: lunar DistroVariant: ubuntu ExtraDebuggingInterest: Yes, including running git bisection searches GraphicsCard: Intel Corporation Alder Lake-P Integrated Graphics Controller [8086:46a6] (rev 0c) (prog-if 00 [VGA controller]) Subsystem: Dell Alder Lake-P Integrated Graphics Controller [1028:0aff] NVIDIA Corporation GA106M [GeForce RTX 3060 Mobile / Max-Q] [10de:2520] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Dell GA106M [GeForce RTX 3060 Mobile / Max-Q] [1028:0aff] MachineType: Dell Inc.
