Hello, On a newly-installed Gentoo guest within Virtualbox 6.1.14 (r140239) running on a Windows 10 host, the shared clipboard and any type of resolution resizing / full-screen fail with the VMSVGA video driver. When starting an Xorg session, the only service taht I see running is: /usr/sbin/vboxguest-service --foreground but I have no clipboard functionality. If I manually start it with `VBoxClient --clipboard` (either as my logged in user or as root), it works (although oddly it spawns two processes). The same method fails when trying to start the video capabilities with `VBoxClient --vmsvga`, either as my user or as root. Doing so results in a black screen and essentially no functionality within the X session, and dmesg shows: >>>>> [ 4.890156] 04:08:01.994550 main VBoxService 6.1.14_Gentoo r140239 (verbosity: 0) linux.amd64 (Sep 16 2020 17:04:28) release log 04:08: [ 4.890359] 04:08:01.995094 main OS Product: Linux [ 4.890612] 04:08:01.995324 main OS Release: 5.8.9-gentoo [ 4.890927] 04:08:01.995551 main OS Version: #3 SMP Wed Sep 16 14:02:04 CDT 2020 [ 4.891478] 04:08:01.995860 main Executable: /usr/sbin/vboxguest-service 04:08:01.995862 main Process ID: 1849 04:08:01.995863 main [ 4.894644] 04:08:01.999251 main 6.1.14_Gentoo r140239 started.
