Description Julian Sikorski 2007-03-26 13:25:13 EDT
Description of problem:
As per summary, as adding vga=791 changes the terminal resolution to 1024x768
when using normal kernel, it does not work with xen one.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. yum install kernel-xen
2. add vga=791 to the boot parameters
3. reboot into xen kernel
Actual results:
Terminal runs at poor VGA resolution

Expected results:
Terminal uses selected vesa mode

Additional info:
It is especially a problem in case of LCD screens, which would otherwise be able
to run at their native resolution.

If i  xen kernel with options as listed below, i do see a 80x60 console till
linux console loads up ( init prompt on screen )

This report targets FC6, which is now end-of-life.

Please re-test against Fedora 7 or later, and if the issue persists, open a new bug.
