Description Rob Rosenthal 2005-03-26 13:28:29 UTC

Recently tried installing FC3. However, right quarter of monitor not being used
and bottom quarter distorted, making it impossible to view/navigate that portion
of screen.  Mouse-click on bottom quarter produced what appeared to be an inch
and a half high cursor. Navigating by keyboard and by guess, able to proceed
with installation of FC3. On reboot, screen corruption persists. Changing
hardware settings to Generic LCD 1024-768 with 60Hz refresh rate and rebooting
did not solve problem.

Installation media (tried two sets from different sources) checked out fine. 
Problem occurs every time I've tried to install FC3.

correctness problems aren't blockers.

it's unclear what version of Xorg you are using.  it would be helpful if you
could confirm that the problem still occurs with CVS or a 6.8.99 snapshot.

Comment 2 Adam Jackson 2005-11-12 20:08:55 UTC

reporter: need more information on you before we can resolve this bug.

suspect this was a symptom of gcc miscompiling libvgahw on some fedora versions.

Comment 3 Mauricio Martinez 2006-01-24 05:08:28 UTC

Similar problem here.

Linux kernel 2.6.15, GCC 3.3.4, Glibc 2.3.4

KM2M motherboard (Athlon XP) ProSavage8 card.

In Xorg 6.8.2, most resolutions work OK. However, 1024x768 @ 44.9 has a 4-pixel 
missing column  at the right edge (the problem seems to be corrected with 
"UseBIOS" "True", but not supported well by my old monitor).

In 6.9.0, 1024x768 @ 44.9 the screen appears totally scrambled (independently of 
 any modules I load). Other modes seem to work ok, but are unsupported by old 
monitors.

Comment 4 Erik Andren 2006-05-31 01:49:17 UTC

Whats the status using a current version of xorg (7.1)?

Comment 5 Eero Volotinen 2006-10-02 00:30:00 UTC

I have about same problem running gentoo's latest xorg-7 and 7.1
and latest savage drivers from gentoo portage.

Comment 6 Tormod Volden 2007-04-25 09:49:18 UTC

Is this still a problem? The gentoo bug was closed as WORKSFORME.

Comment 7 Tormod Volden 2007-06-03 03:18:59 UTC
