hello, i have problems with unblanking in console and x11 in qemu based hypervisors.
the screen does not unblank as a whole on mouse move or when typing to console. https://gitlab.com/qemu-project/qemu/-/issues/2067 https://bugzilla.proxmox.com/show_bug.cgi?id=4786 first stumbled on this in debian 12 installer, and since then, it rendered quite some installations unusable, as you get stuck when you can't refresh the screen anymore. it's a little bit weird that nobody seems to complains besides me, but i can easily reproduce this on debian 12. going back to kernel 5.15 does not show the problem, as there is no screenblanking support in there. not sure if this is related to the builtin vnc in qemu/proxmox or if it's the driver itself. but it's annoying, as you cannot leave debian installation alone for a while, as you need start from scratch after blanking. regards roland sysadmin https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/MAINTAINERS?h=v6.8-rc2 DRM DRIVER FOR BOCHS VIRTUAL GPU M: Gerd Hoffmann <[email protected]> L: [email protected] S: Maintained T: git git://anongit.freedesktop.org/drm/drm-misc F: drivers/gpu/drm/tiny/bochs.c there has been blanking added here: https://lists.freedesktop.org/archives/dri-devel/2021-April/303933.html and there was this fix https://lists.freedesktop.org/archives/dri-devel/2022-September/370781.html
