Valve have been busy, as the latest Steam Beta Client makes some important improvements to the Linux client. The Steam Controller has also seen some improvements, like supporting configurations for XBox 360, Xbox One, and Generic X-Input controller configurator support.- Improved interactions between the Steam runtime and host distribution libraries, which should let Steam work out of the box with open-source graphics drivers on modern distributions. If using an older distribution or running into problems, use STEAM_RUNTIME_PREFER_HOST_LIBRARIES=0 to revert to previous behavior.- Unify close-to-tray behavior with other platforms. If using a distribution that doesn't have proper compatible tray support, use STEAM_FRAME_FORCE_CLOSE=0That particular bug was one I specifically wrote about , as Valve had let it sit at the bottom of the pile for very close to 4 years. I'm actually amazed they fixed it. Funny that they fix it after I highlight it. I've tested it on Ubuntu, and it perfectly closes to the indicator in the top panel now. The only problem is that the indicator menu is now blank, so you have to have an icon somewhere else to click on to bring Steam back up.- Added idle detection, friend status will now automatically switch to Away/Snooze- Fixed Steam not obeying SIGTERM, Steam will now gracefully exit when logging out of a session- Fixed keyboard input and cursor switching in overlay for Vulkan applications- Update Vulkan loader in the Steam runtime to enable Xlib support- Updated libxcb in the runtime with a fix for DRI3-related crashes on open-source graphics drivers
