Red Hat Bugzilla – Bug 495273
UMS:RV370:Radeon X300 assorted fail

01:00.0 VGA compatible controller: ATI Technologies Inc RV370 5B60 [Radeon X300 (PCIE)]
needs to boot with nomodeset, or the display is skewed and distorted. It looks like the stride of each line is incorrect, resulting in almost diagonal stripes across the display.
With nomodeset, the display is almost correct. I have two heads, and the problems are:
- No matter what xrandr options I try, it will only function in mirrored mode.
(FWIW, I see this problem on R580 too).
- The output of the 2nd head is 'shifted' to the left leaving a 2 inch black stripe on the right edge of the screen.
All this is in rawhide, but you may also want to know that the mirror-mode-only bug also appeared in F10-updates very recently.
Created attachment 339153 [details]
X log (with nomodeset)
Does the KMS display look like the screenshot in bug 495297 ?
Could you also boot with drm.debug=1 and dump dmesg (if possible, +Xorg.0.log) via ssh ?
Regarding the mirror-mode only, you may need to add a Virtual line in your xorg.conf to match your total resolution, for instance :
Virtual 3520 1200
Please add the xrandr output as attachement as well.
Could you try again with more recent kernel/xorg-x11-drv-ati packages as well ?
Thanks in advance,

here's the situation with the latest packages..
(various jpegs at
with modesetting enabled, I get strange looking output during boot.
(left head: dsc02051.jpg right head: dsc02052.jpg)
once gdm starts, I can make out the display, though it doesn't look right.
(left: dsc02053.jpg & dsc02054.jpg)
It comes up in cloned mode still. If I use the display config tool to turn off
mirroring, I end up with the display looking like dsc02055.jpg and dsc02056.jpg
Everything looks fine. I can even disable mirroring, and get two independent heads. Though for some reason, it will only let me choose a resolution up to 1280x1024
Trying to set it to 1680x1050 gives me a popup saying
"required virtual size does not fit available size: requested=3360,1050, minimum=(320,200), maximum=(2560,1200)

I see this with kernels 2.6.29.x from updates-testing on rv380 Radeon X600 PCIE.
Earlier kernels are fine.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.
More information and reason for this action is here:
Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue.

This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '11'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 11's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 11 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Closing per comment 8.
