Red Hat Bugzilla – Bug 199133
vesa(4) displays previous session briefly
Last modified: 2007-11-30 17:07:10 EST
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.
Version-Release number of selected component (if applicable):
RHEL 3 update 6 i386
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
The screen displays content from the previous session.
The screen needs to be blank till GUI comes up.
This behaviour is not seen when the manufacturers driver is used.
Need to clear X video buffers to prevent the retention of previous screen
session when starting new X session. Dell bug#199133 linked to IT.

Any update on this one?
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.
