Description Sandeep K. Shandilya 2006-07-17 14:12:46 UTC

Description of problem:

Starting X with low resolutions with the VESA driver causes the previous video
buffer to displayed momentarily. This could be a security issue. The user can
see what was on the previous X session.

RHEL 3 update 6 i386

How reproducible:
always.

Steps to Reproduce:
1.modify xorg.conf to use the VESA driver.
2.startx and run a few client apps
3.quit X windows
4.start X again
  
Actual results:
The screen displays content from the previous session.

Expected results:
The screen needs to be blank till GUI comes up.

Additional info:
This behaviour is not seen when the manufacturers driver is used.

Any update on this one?

Comment 5 John Feeney 2007-07-12 17:28:47 UTC

With RHEL3 now in maintenance mode, where only critical customer issues
can be fixed, this bugzilla has been closed as wont fix due to its severity
level and a lack of recent activity.
