Does the corruption occur if you boot into runlevel 3 and run "startx"

Yes, booting into level 3 and then starting X results in the same display
corruption. Killing the x server returns you to a text mode with similarly
corrupted output. A reboot is required to return the display to something readable.
I have a Via C3 system with the trident cyberblade/i1 graphics chipset. When X
starts (graphical install or system boot) I get a white screen. Dropping to a
terminal I get a corrupted display with vertical bars. If I blindly log in I get
text mode screen with a one character wide blue border. I like to see the
priority get bumped.
I had the same issue when I tried to upgrade to FC4 T3. I ended up not
upgrading and went back to FC3 where I have no problems with the video.
I tried to upgrade to FC4 and the same vertical bars in graphical.

Your problem appears to be different, albiet of similiar nature. I'm running a
few HP Netserver LPr's with the Cirrus Logic GD5480 GFX, and believe me, your
display is much, much more readable than mine!
This is really frustrating for my poor fleet of netservers - Fedora Core 4
brought back support for the NetRaid card (Megaraid) and took away the gfx!
Good luck with this guys, any assistance with this problem would be greatly
I have an Intel G440LX with a Cirrus Logic GD5480.
I experienced the same problem as original poster: boot to X and display is
The solution in bug 161242 (using the libvgahw.a compiled for fc3) made my
display work. I believe this bug is a duplicate of bug 161242. The people
working on that bug believe it is a gcc bug.
Thanks for the update James.
