xorg-server (2:1.13.3-0ubuntu5) UNRELEASED; urgency=low
* Add no-nv.patch: Don't autoprobe -nv on linux.
+ * Refresh drm_device_keep_trying.patch
+ - Make platform devices work correctly, try to obtain busid from
+ path if possible. Fallback if not possible (tegra). (LP: #1161981)
+ - Set empty busid for usb devices, and parse pci path more strictly.
