I have an issue where the console is nothing but a blank screen after grub hands off screen management to the kernel.
This is occurring in both ubuntu server (both a fresh install & an upgrade from Jaunty) and a kubuntu upgrade from Jaunty.
This only happens when I have a vga=NNN option in the kernel command line. If the vga option is missing the console is visible but is in the basic console mode (80x24 IIRC).
Interestingly, it's not related to grub or grub2 as the upgrades still use grub afterwards and the fresh install uses grub2. Either way the symptoms are the same.
Additionally, the fact that the two server-based versions experience this indicates that it isn't an X problem since neither has X installed.
I have also experienced this when the installation is performed on a physical machine and with the install/upgrade performed as a guest within VMware Player.
Any thoughts? Others have seemed to experience this problem but have attributed it to some "modeset" in Intel graphics. None of the scenarios I've encountered have Intel graphics.
TIA
