Plymouth attemps to use video resolutions that HP DL165 G5 LO100i frame buffer does not support

plymouth doesn't set resolutions; the resolution comes from the kernel. Reassigning.

Are there kernel options to try that would work around this?

When I used the defaults in grub2 the display is scrambled from the time the system firmware finishes. No readable messages are displayed after the last firmware message.

When I used "fb=0" or "gfxmode=640x480" kernel messages as readable text appear for an interval of time after the firmware completes. Before the login prompt appears the display resolution is changed to an incompatible one.

Thanks

Uncommenting "GRUB_TERMINAL=console" in /etc/default/grub and then running "update-grub" does not improve this issue.

Uncommenting "GRUB_TERMINAL=console" in /etc/default/grub and then running "update-grub" and then running "update-initramfs -u" does not improve this issue.

I activated the serial console while leaving the KVM switch emulator running side-by-side. The video resolution on the KVM switch emulator display changed when

Begin: Running /scripts/local-bottom ...
Done.
Done.
Begin: Running /scripts/init-bottom ...
Done.

was displayed on the serial console.

System boots from md so it requires /etc/initramfs-tools/initramfs.conf to contain "MODULES=most" or you get

mkinitramfs: missing md root /dev/mapper/rootvg-rootlv /sys entry
mkinitramfs: workaround is MODULES=most
mkinitramfs: Error please report the bug

so adding fbcon and vgafb16 to blacklist.conf will not work.

alias fbcon off FTW

$ cat /etc/modprobe.d/inhibit-fbcon.conf
alias fbcon off

then run:

update-initramfs -u
update-grub

The alternate and server installation media have no work-around for systems where the fbcon, etc modules wreck the display.

Hi nutznboltz,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

In 10.04.1, working workaround is: "vga16fb.modeset=0" (found it on ubuntuforums)
