[Why] Although compositors will add their own modes, Xorg won't use it's own modes and will only stick to modes advertised by the driver. This mean a user that used to pick 1024x768 could no longer access it unless the panel's native resolution was 1024x768. [How] Revert commit6d396e7ac1("drm/amd/display: Disable common modes for LVDS") and commit7948afb46a("drm/amd/display: Disable common modes for eDP"). The panel will still use scaling for any non-native modes due to commit978fa2f6d0("drm/amd/display: Use scaling for non-native resolutions on eDP") Reported-by: Marek Marczykowski-Górecki <marmarek@invisiblethingslab.com> Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4538 Acked-by: Alex Deucher <alexander.deucher@amd.com> Link: https://lore.kernel.org/r/20250828140856.2887993-1-superm1@kernel.org Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
