#18262 new enhancement
Not enough video memory to restart gnome after loading from save state

Description
After saving state, upon reloading a black screen is shown and VM is totally unresponsive.
This is fixed by increasing the default video memory from 16mb to something like 48mb.
Took me a long time to figure out - maybe the default should be larger.

In this particular case I'm refusing to take the easy way out. This should be investigated.
It is for a VM which just uses 800x600 from what I can tell (and 3D is disabled which would change the game noticeably), which needs 2M for the framebuffer. In practice one needs VRAM for at least 2-3 framebuffers for double/triple buffering, but that should still easily fit into the default. For larger screens the situation is different, but that's something for the GUI to detect and offer an easy adjustment.

In this particular case, I agree. But generally speaking, the defaults should change. It has saved us a lot of headaches, just by increasing the VRAM to 32 MB, if not more...
Replying to 0x7766:
Couldn't agree more! The default of 16 MB for VRAM is a "joke" these days. And bumping from 16 to 32 MB isn't that much of a penalty on the overall host RAM usage, in the days of multi-GB allocation for the guest alone.
