Red Hat Bugzilla – Bug 208088
Laptop with ATI Mobility Radeon X700 shows no display
Last modified: 2007-11-30 17:11:44 EST
Description of problem: When installed from scratch, an Acer Aspire 5020 laptop
with an ATI Mobility Radeon X700 PCI-Express graphics card shows no output to
the laptop screen.
Don't know if this is reported against the right XOrg component - sorry.
Version-Release number of selected component (if applicable): Not sure which
component to report the version of.
How reproducible: Every install
Steps to Reproduce:
1. Install from scratch
2. Boot up laptop
Actual results: Blank screen
Expected results: X should work on LCD screen
Additional info: Have found that the display is actually going to the external
montior for the laptop. Using this, I am able to change the detected driver
(radeon) to the fglrx (vendor supplied driver for fglrx cards) driver and the
laptop LCD will begin working.
The bug was happening with an x86_64 install as well as with an i386 install.
Yum updates were done on both installs, but issue was happening before and after
the yum updates.
Please attach /var/log/Xorg.0.log from a blank-screen startup.
also, rpm -q xorg-x11-drv-ati.

XOrg log after boot to blank laptop screen
The screen will render properly on an externally attached screen.
These 3 bug updates are done from a fresh install of FC6T3
The laptop user is reporting that the latest yum update has resolved the
problem. I will verify if this is the case and update the bug as appropriate.
Yeah, I expect this was fixed in 6.6.2-4. If you can verify that I'd appreciate it.
User has done fresh install to have blank screen.
yum update provided new xorg-x11-drv-ati package
Screen now works a treat.
P.S. Hope I resolve this bug properly - I don't normally close my own bugs.
