NVIDIA Releases 550.90.07 Linux Graphics Driver Update Featuring Multiple Bug Fixes

While awaiting the highly anticipated NVIDIA 555 release featuring explicit GPU synchronization and numerous other enhancements, NVIDIA has provided a minor update to the 550 series today, designated NVIDIA 550.90.07, which encompasses various bug resolutions.

NVIDIA 550.90.07 highlights include an enhancement in the nvidia-modprobe command’s capability to ascertain if kernel modules are pre-loaded, remedying an issue that obstructed nvidia-persistenced from activating persistence mode on select systems, applicable to Linux, FreeBSD, and Solaris platforms.

The current release also rectifies an error leading to X server crashes when graphic applications demanded single-buffered drawables with certain functionalities like Vulkan sharpening activated, addresses a race condition that could cause crashes following Xid errors appearing simultaneously across multiple GPUs, and resolves a problem potentially triggering a kernel panic due to an unhandled spinlock release. These improvements affect Linux, FreeBSD, and Solaris systems as well.

Moreover, for all compatible systems, this update mends an issue where additional X screens inappropriately claimed displays assigned to an earlier X screen in the configuration.

For Linux systems, the update fixes an issue that could lead to data corruption when utilizing the GLX_EXT_buffer_age OpenGL extension on X.Org with PRIME render offloading. Additionally, it temporarily blocks the use of the GLX_EXT_buffer_age OpenGL extension on Xwayland to circumvent a bug that could cause corruption.
