Red Hat Bugzilla – Bug 457647
switching between X and VTs with KVM shows VTs dim and poor contrast
Last modified: 2008-10-16 20:07:54 EDT
Description of problem:
Systems attached to kvm (keyboard-video-mouse) have incorrect contrast on
Version-Release number of selected component (if applicable):
Boot F9 into runlevel 5. Use ctrl-atl-Fn to switch to a virtual terminal. The
virtual terminal is extremely dim.
Steps to Reproduce:
1.Boot F9 into runlevel 5
2.Use ctrl-atl-Fn to switch to a virtual terminal
3.The virtual terminal is extremely dim
VTs are difficult to read
VTs have good contrast, which is the case if F9 is started in runlevel 3.
This may be hardware specific. The KVMs are are brand "Kontron", the machines
are Dell 1425 and Dell 1950, both of which use the radeon driver.
I plan on differentiating the KVM brand and video driver next week and posting
more information at that time.

Two blades using ATI/RADEON chipsets show the problem. Other machines running F9, and attached to the same kontron KVM, do not have the problem.
Something in recent yum updates fixed this problem for both machines. I recommend closure.
