After much gnashing of teeth over this issue, after building and installing
vbox 6.1.34 and the oracles-ext package, all issues are gone. The framebuffer
problem is gone on headless access of Archlinux guests and the failure to
redraw widows on move that left artifacts is also gone.
So these issues are fixed in the new release. Good job devs.
Well,
Not quite. Running rdesktop on openSuSE 15.4 beta the resize-hint properly
sets the rdesktop window size, but the OS running in the screen on displays in
a portion of the window while the remaining parts of the windoes are blaock
Essentially, I start my VMs headless from a server using a short script
that launches the VM, e.g.
exec VBoxManage startvm leap_152 --type headless
To start my openSUSE leap 15.2. I then ensure the window size I want is
provided setting "setvideomodehint 1440 764 32". This has worked flawlessly
for the past decade at least. I use the command
VBoxManage controlvm leap_152 setvideomodehint 1440 764 32
But not running on openSuSE 15.4, there are problems that display the
window at the 1440 x 864, but the only regions that shows visible parts of the
desktop are the old FB resolution of 1024 x 768. The rest of the screen is
painted black. It doesn't matter what desktop or OS is running Windows, Linux
with KDE, fluxbox, iceWM. All exhibit the same behavior (but sometimes I can
get Windows to display fully in the 1440 x 864 screen. (after several tries
and reboots)
Checking with xrandr, at least xrandr shows the full window size as the
current mode. So something is preventing vbox from using the full size of the
window and instead uses one of the frame-buffer resolutions. Vbox version is
6.1.34 and host is Archlinux with kernel 5.17.7.
What would cause this problem where there has never been a problem before,
and more importantly, how do I fix or work-around the problem?
