Powered by the latest and greatest Linux 6.14 kernel series for top-notch hardware support, Ubuntu 25.04 features the GNOME 48 desktop environment with the usual enhancements and look that Ubuntu users are used to, specifically the dynamic triple buffering feature for an extra boost on low-end systems.
GNOME 48.1 is here to add support to the Mutter window and composite manager to announce workspace changes to the screen reader and disable HDR (High Dynamic Range) support when using non-atomic (legacy) KMS drivers, along with the ability to fall back to the default color mode when an HDR monitor looses HDR capabilities.
LXQt 2.2 is here to further improve the Wayland session introduced in the LXQt 2.1 release with the ability to set the default compositor and the screen locker by distribution or system-wide, improved support for multi-monitor setups by handling screens by names rather than numbers, and support for the latest stable versions of the supported Wayland compositors.
KDE Gear 25.04 brings improved integration with the Orca screen reader to the Dolphin file manager, which also received support for navigating files with the arrow keys and selecting them using Enter to boost productivity, a new icon that features an actual dolphin, the ability to rename tabs, a more compact status bar, a tidier layout, and initial support for right-to-left (RTL) languages.
GNOME 47.6 brings some interesting changes to the Mutter window and composite manager, including a fix for a black screen issue that occurred on multi-monitor setups when using the NVIDIA graphics driver, support for presentation-time version 2, the ability to honor wl_surface.offset on cursor surfaces, and improved support for sharable surfaces when using NVIDIA as the primary GPU.
The NVIDIA 575 graphics driver series promises support for NVIDIA Smooth Motion, support for GLX front buffer rendering on Xwayland, support for the __NV_DISABLE_EXPLICIT_SYNC environment variable to also apply to GLX and Vulkan apps, and a new conceal_vrr_caps kernel module parameter to the nvidia-modeset kernel module.
