On Virtualbox which has a real framebuffer, it sets the framebuffer size, however with kernel mode setting drivers, they provide a virtual framebuffer device that is the same size as your screen, and override the vga=xxx option.
Unfortunately, even if I did test on Nouveau before this release, it looks more like an issue with Nouveau and your card, and not something that will effect all Nvidia cards. The weston log (loginmanagerdisplay.log) showed nothing wrong, both weston-display-server and weston-desktop-shell are running, and it can't be a mesa issue, because Weston is being called with the pixman renderer for loginmanagerdisplay, I'll see what I can come up with though
In the mean time I am uploading a test ISO here http://sourceforge.net/projects/rebe...s/nouveautest/ which will finish in about an hour or so, which has menu option to pass the Nvidia workaround... When it's done uploading please try to start it just to verify?
Thanks for all the testing.
