Bug Description

Binary package hint: grub2

After a fresh install of Natty on my new PC I noticed that upon booting the characters of grub and the 'scrolling list of messages' were completely illegible. Updates were made but it only showed white blocks where there should be messages. Boot up commenced successfully however.

After logging into the normal unity shell I typed Ctrl-Alt-F1 to go to tty1 and found the situation there similar. I could not read anything.

After some searching I found the following post: and followed the following instructions:

"For example i use Debian within VirtualBox at a resolution of 1280x800 for the console and also for the Xorg server. If you want you to start with this resolution also for GRUB 2 (remember in the past was very limited this feature, and if you are using VirtualBox or other virtualization programs the annoying result was in resizing the window and than enlarging upon the system goes into graphical mode, for example, with the splash screen: usplash, splashy and others), very nice, no more discrepancies between modes: the line to change into the /etc/default/grub file is GRUB_GFXMODE=1280x800 and then issuing update-grub. The resulting action is to write the line set gfxmode=1280x800 into the grub.cfg file."

I used a gfxmode=1280x1024 as this is the resolution of my screen. After this both the tty, grub and scrolling list of messages were legible again.

I think the problem is that the 'gfxmode' was set to a property that my new ATI card could not handle?

If any more information is required please let me know.

Just installed Ubuntu Server 14.04 on an older Compaq desktop for a POC. Install goes fine with no trouble, but I am glad I installed ssh during install because the screen was unusable. The answer here does not work.
