Bug Description

Binary package hint: plymouth

I'm on an old ThinkPad: R30. Ubuntu 10.04 and previous have shown my full screen (XGA) during boot but since 10.10 the boot sequence only uses VGA (800x600)

I wrote VGA but I think it is 600*480 (checked /etc/default/grub) - I can see that dmesg og lspci reports a VGA card but the Triden card is XGA and I run Gnome at 1024*768 with no problems

Thank you for taking the time to report this bug and help to improve Ubuntu.

plymouth can only use the framebuffer device that the kernel makes available to it. Since in your case this is shown to be "ProcFB: 0 VESA VGA", the graphics will be rendered accordingly.

There is some work in progress for Ubuntu 10.10 to let plymouth pick up a framebuffer directly from the bootloader, and the behavior change you're seeing may be fallout from this. Reassigning to the grub2 package as a result, the issue will lie either there or with the kernel

Hi Per,

Perhaps the startupmanager package may help generate the appropriate splash screen in the right resolution. I lack time to explain this but it's worked for me in several configurations. Perhaps try this on a test VM or system and let us know.

Thx to Fabián for trying -
I installed the startupmanager and configured it for the proper resolution and splash and text, but it didn't help - yet. I'll try again
