After upgrading from ''6.1.6'' to ''6.1.10'' (I've skipped ''6.1.8'') I have the following problem: the greeter (lightdm) doesn't span the whole maximized VM window because the resolution is lower, but that should not be the problem, as far as I can remember this always happened on the first display of the greeter after boot.[[br]] But after logging in the screen remains black with a visible mouse cursor instead of displaying my desktop at 1920x1080. The workaround I'm using is sending the guest into runlevel 3 and then again into runlevel 5 so Xorg gets restarted and after doing that I can login successfully into my desktop at the desired resolution.[[br]] So I tool a look at Xorg.0.log soon after boot and then after the telinit workaround.[[br]] I think that the relevant differences are: {{{ 94c94 < (II) vmware(0): Modeline ""800x600""x60.0 42.75 800 850 900 950 600 650 700 750 -hsync +vsync (45.0 kHz eP) --- > (II) vmware(0): Modeline ""1920x1080""x60.0 152.77 1920 1970 2020 2070 1080 1130 1180 1230 -hsync +vsync (73.8 kHz eP) 129c129 < (II) vmware(0): Output Virtual1 using initial mode 800x600 +0+0 --- > (II) vmware(0): Output Virtual1 using initial mode 1920x1080 +0+0 }}} So it seems that 800x600 is available soon after boot while 1920x1080 is not and, after restarting Xorg, the other way around.[[br]] I've tried with Acceleration enabled and disabiled with the same result. I also tried with VBOXSVGA but it has far more Modeline than VMSVGA, including 1920x1080, so there is no such problem with in this case.[[br]] P.S.[[br]] I don't know if it's something related to the problem, since I moved to 6.1 and switched to VMSVGA if missing with the following two commands (see also Ticket #19392), but it seems they aren't working anymore: {{{ VBoxManage.exe setextradata '''' CustomVideoMode1 1920x1080x32 VBoxManage controlvm '''' setvideomodehint 1920 1080 32 }}} anyway the screen was set to the higher resolution available after login and not black.",defect,new,guest additions/x11/graphics,VirtualBox 6.1.14,,1920x1080 login,,Linux,Windows
